PREFACE

While going round inspecting timber areas being worked by European firms in Nigeria, I have often been asked for a book with illustrations showing the different kinds of trees which might be felled, and also giving some account of the trees themselves, as well as the main work of the Forest Department. It is with the idea of trying to supply this want that I have mainly compiled this work, in the hope that, however imperfect it may be, the various timber getters and users in Nigeria may find it useful.

I have not attempted to give accurate descriptions of the trees, as this has already been done by Mr. Foster in his work Notes on Nigerian Trees and Plants, and I would refer readers to that volume, and to the botanical works, such as Useful Plants of Nigeria, issued under the authority of the Director of Kew Gardens, and the Flora of Tropical Africa, by Oliver; but only refer to some specific feature of the trees that are most common or useful, by which they can be recognized by an ordinary observer without botanical knowledge.

I wish to acknowledge with thanks the assistance given to me by the Central and Southern Secretaries for permission to use the annual Forest Report from the year 1906 onwards.

I wish also to express my thanks to the Under-Secretary of State for the Colonies for permission to use my Reports on the Forests of Sierra Leone and the Afforestation of Togo.

To Mr. H. N. Thompson, the Chief Conservator of Forests of Nigeria, I am indebted for much useful information obtained from his Report on the Gold Coast Forests.

To Mr. R. E. Dennett, Deputy Chief Conservator of Forests, who has given me much help and advice in compiling this work, and more especially for reading through the proofs, I tender my grateful thanks.

Two most valuable chapters on the Forests and botanical features of the Northern Provinces of Nigeria were written by Dr. J. M. Dalziel, to whom I owe grateful thanks for his encouragement in this work.

My greatest thanks are due to Mr. C. E. Lane-Poole, Commissioner of Forests, Victoria, for the use of the list of the Sierra Leone trees.

To M. Chevalier I return grateful thanks for his list of the Ivory Coast trees.

For the constant and unfailing interest and devotion to the work of Miss Christina E. Lacy, acting as amanuensis, I beg to extend my heartfelt thanks.

Further thanks are also due to my wife, who has lent not only practical assistance, but has been the mainspring of inspiration for the completion of this work.

WEST AFRICAN FORESTS
AND FORESTRY

CHAPTER I

THE FORESTS OF WESTERN AFRICA

From a large scale-map of Africa, the various British West African Colonies and Protectorates, as well as Liberia, French Ivory Coast, the late German Colonies of Togo and Cameroons, can be seen on the western side of that Continent. In fact, these territories are all within the Tropics, and also between the latitudes of 13° North in the Gambia to nearly the Equator in the Cameroons, and between longitude of 17° West to 10° East. Roughly speaking, Upper Guinea, as this part is usually called, covers an area of 100 to 200 miles wide by a length of over 1,500 miles, as a sylvan belt mainly of one type of vegetation, which botanically, however, only begins to alter as the boundary of the Cameroons is approached in the eastern part of Nigeria. Therefore one finds several trees extending right through this area, and also an almost unbroken forest all the way along the coast line, and roughly 100 to 150 miles inland. The width of the forest varies rather according to the aspect of the coast line, because the prevalent wind being south-west, the greatest rainfall, and thus the heaviest type of forest, occurs when the coast line runs at right angles to the prevailing wind. This occurs, for instance, near Calabar, Nigeria in the Cameroons, part of the Gold Coast near Axim, and Sierra Leone near Freetown. In some instances this effect is accentuated by the proximity of mountains near the coast, as, for instance, north of Calabar and north of Benin. One tree, which might be taken as a type, is the Rhodesian Mahogany, Afzelia Africana, which is found right in this belt of forest on its northern side. As the name implies, it is also found in Rhodesia, near the Victoria Falls. Mahogany, Khaya Senegalensis, is another tree found in the Gambia, also in Nigeria right up to the Cameroon border, over 1,500 miles away.

However, in this huge forest belt there are great variations in the rainfall, from 20 to over 175 inches in the Oban Hills of Nigeria. There are also, naturally, variations in soil and elevation, which make differences in the character of the forest. The proximity to the sea causes yet another difference in the type of vegetation, combined as it often is with low elevation.

Broadly speaking, then, one can differentiate several distinct types of forest, though owing to slight changes in a locality the one merges into the other and very sharp boundary lines cannot be drawn.

I. The Mangrove Swamps are usually near the sea coast, though not always at the sea coast; a strip of Evergreen Forest is usually found actually on the sandy dunes of the sea coast. The Mangrove Swamps also extend up the rivers near the coast as a fringe a mile or more wide.

II. The Evergreen Forest is usually found on the sea coast, also extending inland up the rivers, and also on low land up to an elevation of a few hundred feet, as, for instance, the forest on the banks of the Calabar River.

III. The Freshwater Swamp Forests are also found in this type of locality.

IV. The Mixed intermediate Forest is found usually where the rainfall does not exceed 60 inches, or in slightly hilly country, and contains a few deciduous trees. Typical trees of this forest are the Triplochiton Nigericum and Mimusops multinervis. It contains both evergreen and deciduous trees.

V. The Fringing Forest, or “Gallerie” Forest of the Germans, is found at the edge of rivers or lakes, where the rainfall is otherwise too low for the mixed deciduous forests.

VI. The Savannah Forest, sometimes so-called Dry-zone Forest, usually occurs with a rainfall of 30 to 50 inches. The typical tree of this is the Lophira alata.

VII. The Evergreen Forest of the hills, chiefly above an altitude of 2,000 or 3,000 feet. It is especially noticeable on Mount Itakum and the Boji Hills (elevation 5,000 feet).

VIII. The Open Orchard Forest, with shrubby trees of small growth.

These, then, roughly follow the Œcological Divisions according to Warming, which are as follows:

- Mangrove Swamp,
- True Savannah,
- Treeless Savannah, low and high grass,
- Bush Savannah,
- Tree Savannah,
- Savannah Forest,
- Sclerophyllus formations, such as
- Bush and Forest,
- Bamboo Forest.

Forests are in addition named after the locality, such as Benin Forests, Oban Forests, Ondo Forests. Again, yet another nomenclature is after the kind of tree represented, such as Evergreen Forest, where all the trees are evergreen all the year round; for instance, Calabar Forests, Ondo, South Benin.

The mixed forests and intermediate forests, where the trees are both evergreen and deciduous, growing side by side, such as Olokemeji Forests, Benin Forests, Obubra Forests, and Bende Forests. Thus summarising the Nigerian Forests, we get the following formations:

1. Nigerian Swamp | Evergreen: Mangrove, type tree.
2. Evergreen Forests | Lophira procera, Parinarium.
2a. Freshwater Swamp Forests | Cynometra mitragyne.
3. Mixed Deciduous, intermediate Forests | Triplochiton, Iroko, Chlorophora excelsa.
3a. Fringing Forests | Mixed, deciduous really.
4. Canopied Deciduous Forests (sometimes termed dense Savannah Forests) | Olokemeji: Berlinia, Afzelia.
5. Open Deciduous Forests | Paradaniella Oliverii, Eugenia Owariensis, Terminalia Togoensis.
6. Tree Savannah Orchard Forest | Lophira alata, Shea butter, Acacia; Iwu, Oyo, Ndeh.
7. Treeless Savannah | Grass, a few stunted bushes of Acacia Isoberlinia, North Ogoja.

CHAPTER II

THE GAMBIA

In the early part of the nineteenth century a considerable quantity of African Mahogany, obtained from Khaya Senegalensis, a dry-zone mahogany-tree, was shipped to England; in fact, this was the original source of African Mahogany, as also it was the first tree from which it was obtained. Even now this tree is one of the most prevalent in the strip of land on both banks of the Gambia, so far as British territory is concerned.

At the present time no mahogany is being shipped from the Gambia, but recently an Ordinance was passed regulating the cutting of firewood and forest trees.

Forests in the ordinary sense of the word cannot be said to exist in the Gambia, but no doubt a considerable amount of timber could be obtained from the dry-zone country. The total length of the colony is 300 miles, and approximately 5 miles wide, on either side of the Gambia River, which makes it in the aggregate a considerable tract of country, in all 4,500 square miles, of which the colony proper occupies 4 square miles.

So far only Rosewood (Pterocarpus erinaceus), Mahogany (Khaya Senegalensis), and small pieces of Baywood, probably also a mahogany, have been reported from the Gambia. In 1908 a certain amount of wood was cut for the making of charcoal by a man from the Canary Islands. In 1909, 102 tons of charcoal were exported, and in 1910, 176 tons, valued at £634. Since then no other returns are available, so apparently this industry has come to an end. There is no Forest Officer in the Gambia, and no proposals for Forest Reserves have been put forward by the Government. Part of the land near the mouth of the Gambia is swampy and covered with the usual Mangrove forests.

In the Bulletin of the Imperial Institute, vol. viii, 1910, p. 244, it is stated that the specimens of rosewood and mahogany forwarded to the Imperial Institute were reported on as follows:

Rosewood (Dalbergia sp.), reddish-yellow with darker lines and red pores, solid and compact, resembling rosewood except in colour. The timber would not pass as rosewood on the market. It has an agreeable odour, is hard and heavy, weighing 45½ lb. per cubic foot. It turned and polished well, sawed very easily, but was difficult to plane; planing left a smooth, bright surface.

Mahogany (Khaya Senegalensis) may be looked upon as inferior baywood, the wood light in colour, of poor figure, hard to plane, but when planed leaves the surface bright and woolly in alternate bands; very cross grained, sawed and turned easily. Weight, 41½ lb. per cubic foot. Should be very useful locally, but probably not of sufficient value for much export trade.

Even in this comparatively small colony a certain amount of forest land should be preserved, more especially that which is unsuitable for agriculture. In every country there is always some poor or rocky land which is not favourable to the growing of agricultural crops.

The oil palm is another useful tree, which yields the well-known palm oil and kernels; however, here the oil is required locally for alimentary purposes, and therefore only the palm kernels are exported.

The following shows the exports for five years:

Year. | Tons. | £ | s. | d.
1910 | 467 | 5,640 | 0 | 0
1911 | 443 | 4,756 | 0 | 0
1912 | 445 | 6,518 | 0 | 0
1913 | 545 | 9,026 | 0 | 0
1914 | 494½ | 7,814 | 17 | 11

It will be noticed that the very high prices ruling for part of 1913 and the beginning of 1914 had the effect of causing increased exports to be made.

Here, as in the case of other products, planting could be undertaken with advantage, as the yield of kernels and oil is good; even if the increased amount of oil produced was sold locally, the increased output of kernels would find a market in England, where they are needed.

It is a tree which allows cultivation of field crops to be made between the oil palms for several years before the palms become too big and shut out the light necessary for field crops. In the drier climate of the Gambia a planting distance of probably 16 feet would be sufficient to ensure a good yield, and yet give sufficient distance between the trees to allow room for them even when mature.

If an Agricultural or Forest Department, which at present does not exist in the Gambia, could not supply young seedlings or nuts for planting, one of the trading firms could secure them from one of the other West Coast Protectorates. Of course, in many cases, if the natives could be induced to believe that a good price would always be paid for kernels, they would no doubt make small plantations of oil palms themselves, as some fruit always falls to the ground in the picking, is thus not boiled, and so is suitable for furnishing seed for planting. It is, of course, inadvisable to plant boiled nuts, as many do not germinate, owing to the germ having been destroyed by the boiling of the fruit; others do, however, as can be seen in the young oil palms sprouting from heaps of uncracked nuts which the natives leave near the villages.

CHAPTER III

SIERRA LEONE

I. The Forests.

The Colony and Protectorate of Sierra Leone cover an area of approximately 34,000 square miles, or, to make it more comprehensible, it is almost the same size as Ireland. Probably in the earliest times the whole territory was covered with some kind of arborescent growth, varying from open savannah and deciduous forest to close, impenetrable evergreen rain forest.

Now scarcely 1 per cent. of this forest remains, one of the most important tracts being the Sierra Leone or Peninsular Mountain Forest, situated on the mountain due east of Freetown. The whole of this region was once covered with forest, now reduced to an area of approximately 48 square miles, or 30,000 acres. All this tract down to the 500-foot control line has been reserved as a permanent forest, so that eventually the whole peninsular forest will have an area of 75 square miles. Illustrations Nos. 2 and 4 show a general view of these forests.

Other important mountain forests are those situated on the Kassewe Hills, Kagnari Mountains, Kambui Hills, Panguma Hills, Nimmini Mountains, Loma Mountains, Bunbola Hills, and Maramper Hills. In addition to these areas, timber trees are felled at Kangahan and Yonni, as well as in the peninsular mountains and Maramper Hills, especially for local use.

Turning now to a consideration of the forests more in detail, one naturally first deals with the most accessible ones, i.e. of the peninsular mountains. From the beautiful harbour of Freetown, Sierra Leone, one sees the edge of these forests between Leicester Peak and Sugar Loaf Mountains. From these two points it skirts the hill station, extending thence roughly parallel to the sea as far as Kent; the largest wooded slopes face the ocean, only a narrow strip of forest being found on the landward side of the mountains near Burehtown and John Obey. The forest extends practically from the water’s edge on the estuary of the Bureh River right up the mountains to an elevation of 2,000 feet, with a rainfall of upwards of 160 inches per year. Silvan vegetation is very luxuriant, the giant trees standing close together, often entwined and joined to each other by various large creepers, the whole forming an almost impenetrable grove, into which only the diffused light of the sun reaches. The undergrowth is not very thick, except where old trees have fallen or where mature trees have been felled; this is partly owing to the dense shade of the tall trees, and therefore the trunks of these trees can be seen. A large Cedar Mahogany 23 feet in circumference was seen. This specimen of a mahogany was one of the largest trees found, and shows to what size the trees attain in this peninsular forest. One of the commonest trees found is the Red Ironwood, or sometimes called in Sierra Leone Ironpost, botanically known as Lophira procera. A picture of a large specimen of one of this species is shown as illustration No. 2. Another very common tree is a species of Mimusops, known as pearwood, or sometimes mahogany, when sold as timber. The African Violetwood, sometimes known as Blackwood, is comparatively common. Rhodesian Mahogany, usually called Kontah, botanically known as Afzelia Africana, is also found. Real African Oak (Oldfieldia Africana) is seen singly scattered throughout forests. A patch of true Gum Copal trees is found, as well as isolated specimens in some parts of the forest. Rock Elm (Chlorophora excelsa) is seen both in the forest and in the clearings made for farms. The Oil Palm (Elaeis guineensis) is sparsely distributed in the forest, but more frequent in the abandoned farms. The above-named trees are representative of some of the very large number of hardwoods and other trees of economic value in the forest. There are, however, also a very large number of softwoods found scattered amongst the other trees in the forest; a beautiful Whitewood (Alstonia Congensis) is, for instance, one of such softwoods. The Cotton Tree (Eriodendron anfractuosum) is probably the one most commonly found. Various Albizzias are also met with in a similar manner.

II. Notes on Timber Trees.

Taking now the different species of timber trees individually, the following are most important:

1. Real African Oak (Oldfieldia Africana), which is termed Tortorza by the Timanis and Paulai by the Mendis. As illustration No. 5 shows, this is a very large and tall tree. It often attains a bole length of 50 feet and a girth of 16 feet. It is found singly, scattered through the forest. The habit of its branches, open crown, and greyish bark make it look not unlike a European oak. In reality the bark is scaly, gradually peeling off in flakes. The tree in illustration No. 6 shows this characteristic peculiarity to advantage, and also shows a medium-sized tree, approximately 10 feet in girth. The tree fruits moderately, and has an indehiscent capsule not unlike the shape, size and colour of an oak-apple. The capsule has five faint ribs on its surface, but contains only three seeds. The little seedling, with light grey stem and white lenticels, is easily recognized. It usually has also only three leaflets on its leaves, instead of forming true digitate leaves as a full-grown tree. The sapling once started shows fairly rapid growth, and during the early years stands a good deal of shade. It should therefore be classified as a slight shade-bearer. African Oak is a dark reddish-brown wood, which is very hard and most durable. It has, of course, a much closer grain than ordinary oak. A very smooth surface can be obtained by planing the timber. Locally, small trees are cut for conversion by pit-saw into timber for boat keels. This timber was exported as teak from Sierra Leone 1827 to 1835 for use in the English Navy. It was afterwards lost sight of, though the natives continued to use it locally. During 1908 a few round logs of short length (12-16 feet) of this timber were exported to England and sold in a Liverpool market for 2s. 6d. per cubic foot (extreme measure).

2. Ironpost, or African Oak, or Red Ironwood (Lophira procera), is the most common tree throughout the peninsula. According to the Conservator of Forests in Sierra Leone, 80 per cent. of the trees of the peninsular forest are Lophira procera. All stages of growth are found, from the smallest seedlings to the largest tree, over 100 feet high and 20 feet in girth. In the forest the tree has an orange-coloured bark, which rapidly turns grey when exposed to the rays of the sun. The bole is not always quite cylindrical, especially near the base, where it often develops rather angular root protuberances. This seems to occur more often on rocky ground, such as that where the tree is found in the peninsula. For a similar reason the bole is not always straight, though in the ordinary way the tree has a comparatively small crown with short branches. Thus, in proportion to the size of the tree, the bole is very long, the twigs are thickish, and the long thin paper-knifelike leaves appear at the ends of them. Seedlings seem to come up wherever suitable conditions of reproduction are found. A clear bole is typical of these trees in the pole stage of growth. Illustration No. 2 shows a large specimen on the edge of the forest, and there are many large trees with the peculiar root protuberances, growing in the forest. The timber is very hard and of a dark red colour, which it retains when dry. The heartwood forms comparatively early in the life of the tree, and although the sapwood is white, it is almost as hard as the heartwood. For this reason comparatively small trees yield timber, and thus can be felled earlier than trees in which the heartwood forms later. Of course, in this connection it should not be forgotten that the market does not desire logs of too small a size, i.e. of 18 inches or under, when squared. Locally this is known as Ironpost, and is sold for house-building, and, as its name implies, it is used for the uprights of the house. The Public Works Department have a regular schedule of timbers which are used, and this timber is mentioned amongst them, and is bought from native contractors at 3d. per superficial foot for boards, and 3d. to 6d. per linear foot for beams and posts. This timber has been used as a substitute for real African Oak, when it is sold as African Oak. A regular supply of logs could be obtained from the peninsular forest.

3. Cedar Mahogany (Pseudocedrela sp.; termed Bissimi by the Mendis). This tree, which grows to a very large size, is not very prevalent. The largest tree, some 23 feet in girth, was found above the Gumah. The bole is usually very long and straight, which makes it very cylindrical. This last characteristic of the tree is all the more accentuated by its having no root projections at its base. This species appears to be one of the largest trees in the forest. It is apparently a very fast-growing tree, forming heartwood comparatively early, though the sapwood is rather wide (up to 10 inches in a tree 7 feet in diameter). This timber has not been exported, but wood from similar trees on the coast has been exported and sold in the European market as mahogany (scented). There is no reason to believe, therefore, that the wood from this tree would not fetch a similar price. Owing to this tree being so fullwooded, a larger proportion of the bole can be converted into logs than is the case with other kinds of mahogany trees which have large root flanges.

4. African Walnut (Lovoa Klaineana). This is a medium-sized tree of the Mahogany family, which, owing to the brown colour of the wood, has been termed African Walnut in the timber trade. Although not very prevalent, it yields one of the timbers suitable for export.

5. Satin Mahogany (Guarea sp.) is another medium-sized tree which is prevalent in most parts of the peninsula. The grain of the timber is of course similar to Mahogany, as the tree from which it is obtained belongs to the Mahogany family. The timber when planed has a satiny sheen on it, which may make it valuable in the European market. It has not been cut for local use.

6. African Pearwood (Mimusops sp.) is a large tree with a good bole of fair length. Only a moderate number of this species were found, but there are at least two, if not three, other species of Mimusops which yield a timber which has been sold as mahogany. The grain of the timber of the first-named tree is more open, sometimes figured, and of a lighter reddish colour than the other species. These other trees yield a dark-red timber of close grain, which is much harder than mahogany. These Mimusops are found at a higher altitude than most timber trees. The forest, therefore, above an elevation of 2,000 feet, is much more valuable owing to the presence of this tree. These trees attain a girth of 12 feet and a height of upwards of 150 feet. The bark of the trunk of the tree is smoother than that of mahogany.

7. White Mahogany (Canarium Schweinfurthii), also known sometimes as Gaboon Mahogany, is a very tall forest tree which attains a bole length of 70 feet, with a girth of 10 feet. It is not very plentiful, but is one of the light-coloured species of mahogany. It has a definite shipping value of 2s. 6d. in the round per cubic foot.

8. African Mammee or Mammy Apple (Ochrocarpus Africanus) is a large tree attaining a girth of 10 feet, with a bole length of 30 feet. It is moderately prevalent. The timber has a pretty grain, and is of a reddish colour, which is similar to mahogany.

9. Dita (Detarium Senegalense) is a large tree with the bole length of 30 feet and a girth of 12 feet. Although it is not a very common tree, it is a useful addition to the number of trees which yield timber similar to mahogany. The fruit is large, has an edible pericarp, and is sold in the market under the name of Dita.

10. Red Cedar (species of Sterculiaceæ) is a large and straight-growing tree, which reaches a girth of 10 feet. The tree has very characteristic root flanges, which can be seen in illustration No. 10. The timber has a mahogany-like grain, though of a somewhat more open texture. It is one of the most prevalent trees in the peninsular forest.

11. Kontah, or Mahogany (Afzelia Africana), is a large tree with oval crown and bole length of 30 feet. Only a few specimens were met with in the forest, though the tree often grows up in old clearings. The timber is of a reddish-brown colour, somewhat hard and very durable. It takes the place of an oak timber economically, although it is not really of that type. The grain of the timber has much longer and more open pores than oak, though it could probably be sold as an oak or teak substitute in the European market.

12. Rock Elm, also known as African Oak or Teak, is a common tree attaining large dimensions. Being a very durable wood of moderate hardness, it largely takes the place of European oak in the economy of the country, which, with its yellowish light-brown wood, rapidly becoming a nice old-oak brown colour, makes it a very similar timber, although, as the first name, Rock Elm, indicates, the tree is botanically a member of the Elm family. White ants occasionally attack its sapwood, but make no progress in the heartwood. The wood is not attacked by fungi to any extent. Wherever the rainfall is sufficient, seedlings of this tree come up in the old farms, and when cut down it sprouts again from the stump.

13. East Indian Walnut (Albizzia Lebbek) is a medium-sized tree which grows very quickly. The heartwood, which matures comparatively early, is a light-brown colour, similar to walnut. The timber has an open, pretty grain. It is one of the trees which comes up in old farms, provided rainfall is moderate.

14. Satinwood (Zanthoxylum macrophyllum) is a medium-sized tree with a clear bole of 30 feet, combined with a narrow crown and small branches. It is a very common tree in the peninsular forest, and it is also found growing up in the old farms, where the rainfall is adequate (60 inches). The wood is the typical light-yellow colour. The grain of the timber is very fine and hard, which makes it less liable to shrink than other more open-grained woods. The heartwood forms early, though where trees grow up very quickly, roughly only half of the diameter width of a tree is made of heartwood. That is to say, in a tree a foot in diameter, approximately 6 inches will be heartwood. In the evergreen forest there is another species of Zanthoxylum which attains a rather larger size than the first named. It is, however, not quite so prevalent as the other species. In common with other species of Zanthoxylum, it bears all round the stem extremely large woody spines. In this species the spiny protuberances are exactly like small round cones of wood, with a diameter 2 inches at the base. Yet a third species of Zanthoxylum Senegalense yields a similar satinwood, almost as close grained, which, however, is found growing as a small tree at the edge of the deciduous forest before the dry-zone belt is reached. This tree is characterised by its much smaller leaf, with pinnæ broader in proportion to their length than the former species. In a similar manner the woody protrusions on the stem do not project more than three-quarters of an inch from it, compared to those of the second-named species, which attain a length of 3 inches. The timber of this dry-zone Satinwood is just as valuable as the former species. It is fairly prevalent in the more open forest where it is found. It withstands the annual grass fires to some extent, and seedlings appear in the neighbourhood of mature trees.

15. Violetwood is a medium-sized tree with a smooth bark not unlike beech, and a bole of up to 20 feet in length and 12 feet in girth. It is, however, a little crooked in growth, but this is not an undesirable feature, because the texture of the grain often thus becomes figured. Specimens which were collected showed this growth, and a few species had a very pretty figured grain. It is quite a common tree in the peninsular forest. The fruit of this tree is a pod about a foot long and an inch wide, containing on the average eight oblong flattish beans. The wood is of a greenish-brown colour, and is very hard, heavy and durable, judging by the timber of fallen trees. The timber when planed has a scent of violets, hence the English name which I have given to it. The tree has not been cut for use as an export timber, though it is well worth a trial. It is not used locally, so that all available supplies of timber could be used for export.

16. Pterocarpus erinaceus (African Rosewood) is a small tree of the savannah forest, which is found in the Karina district and other parts of the country. It is one of the commonest trees, and occurs in small groups scattered throughout these forests. The timber is a reddish-brown colour and of a similar texture to the ordinary Camwood or Padauk, of which genus it is a member. The wood, however, of this species is much harder than that of the others, and the coloration is often partially streaked, both features being due probably to the much slower growth owing to the annual grass fires. From the neighbouring territory of Senegal the timber has been exported to France as African Rosewood, where it finds a good market; but it is doubtful if it could compete with the Bahia Rosewood in the English market, owing to its less brilliant colour; the timber is, however, worth a trial.

17. Baphia nitida (Camwood) is a small-sized tree, which is commonly found at the edge of villages and in old farms. It is a somewhat slow-growing tree, in which the heartwood forms none too early and in a somewhat irregular manner, occasionally small patches forming comparatively near the bark. The wood is hard, and the heartwood of a deep claret-red colour. The timber is close grained and of fine texture, which planes very smooth after being cut and dried. In recent years much smaller quantities of Camwood have been sent away (see Appendix I) than between the years 1827 and 1835 (see Appendix II), when between 5 and 802 tons were exported. In this connection, too, there can be no doubt that Camwood is obtained from the tree known botanically as Baphia nitida, because this tree is found in Sierra Leone, whereas Barwood, or the so-called Camwood of Nigeria, the produce of Pterocarpus tinctorius or Osun, which has not yet been reported from the neighbourhood of Sierra Leone, could not have been absolutely killed out between the years 1835 and 1900.

III. Trees Cut for Local Use.

1. Morinda citrifolia? (the Brimstone) is the most common tree, from which the largest amount of timber which is used locally is obtained. Growing, as it does, with a girth up to 20 feet and a bole length of 50 feet, the local sawyers can usually make a very large number of 12-feet planks 1 inch thick out of each tree. The chief use of this timber is for weather-boards, which are sold at 10s. per 100 feet. All the native houses in Freetown are faced with weather-boards of this kind of timber. After being cut down, shoots sprout out from the stump, forming in a few years small trees of useful size, especially in old farms. The name of this tree, Brimstone, denotes the wonderful sulphur-like colour of the wood. The durability of this timber for outside work and its termite-resisting qualities have given it a premier position amongst local timbers. The Brimstone has a fruit not unlike coffee, and bears seeds plentifully; it should therefore not be difficult to raise seedlings for making plantations. The trees grown from stool-shoots do not appear to attain nearly such a large size as those grown from seedlings in the forest.

2. Chlorophora excelsa (Rock Elm, African Oak) is a common tree which is cut for local use. The heartwood, which rapidly darkens from a light-yellow brown colour to a dark old-oak brown colour on exposure to air, is very durable for inside or outside work. Though white ants attacks and destroy the sapwood, they make little or no progress in properly seasoned heartwood. Locally it realises 10s. per 100 feet. It is plentiful, and has a distinct tendency to spread into old farms, where the seedlings have more light to develop than in the forest.

3. Iyawey (Red Cedar, or Isganwe) is also a common tree which is cut for local use. It is a large and straight-growing tree, and attains a girth of about 10 feet. Owing to the wood being comparatively soft, easy to saw and of a nice red colour, it fetches 12s. per 100 feet, which is more than is obtained for several other local timbers.

4. Oldfieldia Africana (Black Oak, Beechwood) is cut for local use, for sale as planks at 2¼d. per foot, and uprights and beams at 3s. per cubic foot. One of the chief uses of this timber is for the keelsons of the locally made sea-going boats. Owing to the difficulty of the local sawyers in handling heavy logs on the raised wooden pit-saw framework on which the logs are sawn, only comparatively small trees are felled, and consequently there is more waste, and undersized trees are prematurely sacrificed owing to the poor methods of the local sawyers. Less timber, especially heartwood, is thus obtained.

5. Parinarium sp. (White Oak) is a moderately common tree. It attains a good height and a girth of 12 feet. It has large root flanges reaching about 10 feet up the bole. Although a somewhat hard wood, it is used locally either as planks and posts or as beams and logs. It is said to be durable, and is worth 2s. per cubic foot when sawn.

6. Afzelia Africana (Mahogany, Kontah) is a medium-sized tree which is not very prevalent in the forest, but is much more so outside in the open forest country. The timber, which is hard, has an open grain with a good yellow-brown colour, not unlike Iroko. It is very durable, and used as planks and logs. In the plank it is sold at 6d. per superficial foot, and in the log at 3s. 6d. per cubic foot. This is considered one of the best local woods, partly owing to its grain being somewhat similar to mahogany. Seedlings appear in old farms where there are but few grasshoppers. Otherwise trees grown in a nursery are attacked by these insects, as well as by rodents of different kinds.

7. Daniellia Ogea (Blue Bessie) is sold as planks at 3d. per superficial foot. It is closely related to Paradaniella Thurifera; the former tree is more prevalent in the green forest, and the latter in the open deciduous forests, which attains a girth of 10 feet and a bole length of 30 feet, while the first-named species reaches a girth of over 20 feet and a bole length of over 100 feet. It is sold locally chiefly for house-building.

8. Griffonia palescens Koronko is felled for sale as planks at 2½d. per superficial foot.

9. Coula edulis? (Almond Wood) is a medium-sized tree which is cut into planks 1 to 2 inches thick and up to 12 feet long, and sold at 2½d. per superficial foot.

10. Rhizophora racemosa (Mangrove) grows in pure “stands” in the swamps near the sea coast, chiefly in the estuaries of the rivers. It attains a girth of 4 feet and a height of 80 feet. It is sold as poles 9 to 12 feet in diameter at the rate of 2½d. per cubic foot. Very large areas of mangrove forest occur, so that ample supplies of this kind of timber are assured. Locally it is often used for house-building, and is preferred to many other timbers.

11. Ochrocarpus Africanus (Mammy Apple) is a large tree attaining a girth of 10 feet and a bole length of 30 feet. It is evidently not so prevalent as it used to be, owing to the fact that the best trees have been felled. Seedlings, however, appear very readily from the large fruit when it falls in suitable germinating places in the forest. It is much prized locally on account of its pretty grain and red mahogany-like colour. It is sold as planks, joists or posts at 3d. or 3½d. per superficial foot.

12. Anisophyllea laurina (Monkey Apple) is a very lofty tree, attaining a girth of 12 feet and a bole length of 40 feet. Although moderately prevalent in the forests, it is very plentiful outside in the deciduous forests. It shoots up very strongly from the stump after an old tree has been cut down. Wood obtained from these stool-shoots is, however, not so good or of such large size as that obtained from seedling trees. The timber is a light-brown colour, but a very pretty grain, full of medullary rays, giving it a sheen not unlike oak. Locally it is sold as joists and posts at the price of 3d. to 6d. per superficial foot.

13. Lophira procera (Red Oak, Kokank, also known as Ironpost) is sold as planks, posts and beams at 3½d. to 6d. per superficial foot. It is chiefly used for house-building. A full description of this tree is given under the heading of the export timbers, so that nothing more need be added here.

14. Parinarium excelsum (Rough-skinned Plum) is a very common tree, which attains a girth of 12 feet and a bole length of 30 feet. It yields a hard timber with open grain. It is sold locally as planks or logs at 6d. per cubic foot for building timber. The fruit, which, as the name indicates, is like a green plum, is covered with white lenticels, making the surface very rough. The flesh is of a yellowish colour and soft, with a pasty nature. It has a sweet, pleasant taste. The wood, when freshly cut, has a sweet, beeswax-like scent, similar to that of the fruit.

15. Whismore, which is sold as planks at 2½d. per superficial foot, is another very useful timber, not unlike cedar in texture. The tree comes up very readily in old farms, and has very large tripinnate leaves. Apparently it grows very fast, though this does not appear to hinder the early formation of heartwood, which is of a very light brown colour, though the sapwood is quite white. It attains a girth of about 9 feet and a bole length of 50 feet. The bark forms very characteristic fissures, dividing it into more or less diamond-shaped pieces, rather reminiscent of the European Elm. Although the tree does not occur in actual groups, more than one will usually be found in the same locality.

16. Uapaca Heudelotti (Sugar Plum, Red Cedar) is a large tree with rather a spread of crown and numerous aerial roots. It attains a girth of 9 feet and a bole length of 20 feet. The timber has a close and fine grain, and is of a reddish colour. Locally it is cut and used for the ribs of sea-going boats. It is apparently quite durable for this purpose. It is very prevalent, and usually grows near waterways.

17. Pycnanthus Kombo (White Cedar) is a very large tree which attains a girth of 12 feet and a bole length of 80 feet. It is very prevalent, and can be recognised by the flat crown and long straight branches coming out at right angles to the stem. When cut it exudes a reddish-coloured mass of semi-liquid nature. The bark reminds one of the Mahoganies, though on the whole it is more fissured. The timber is soft and of a pinkish colour, though it gives more the impression that it is white and tinged with red. It has a very open grain with particularly long pores, reminding one of cedar (Cedrela). It is cut locally for sale as planks.

18. Pterocarpus Erinaceus (African Rosewood) is mentioned amongst the number of possible export timber-bearing trees. It is also used locally in the making of a musical instrument called Balangi, after the timber has lain some months in the ground. In the drier portions of the country it is a useful tree for house-building. It seeds readily, and is usually found in large quantities.

19. Baphia nitida (Camwood) is also one of the export produce bearing trees, but which has been used as a colouring matter for putting on the body from time immemorial. The local people, however, prefer to use cakes of the ground-up produce of the Barwood (Pterocarpus Tinctorius) from Southern Nigeria, which commands a higher price. That this product of Baphia nitida is the true Camwood is practically proved by the fact that this tree was first identified from Sierra Leone, whence it is all exported, and also by the fact that Barwood, or the Southern Nigeria Camwood, is not found in Sierra Leone.

Although the above completes the description of the most important local timber trees, there are many others which might be used with satisfaction. One of these trees, known as Yabonji by the Mendis, has a grain, colour and softness similar to white pine, and is sold locally as yellow pine. Erythrophlœum Guineense (Sassybark) yields a hard timber suitable for bridge-building, as it is very durable and grows to a large size, though not always with a very long bole. Mountain Mahogany, a species of Lonchocarpus, has a grain similar to pine, with resin-like canals in the wood. It grows to a large size, with a straight bole 50 feet in length and a girth of 10 feet. Combwood (Conapharingia pachysiphon) is a small tree, which yields a yellow wood similar in texture and grain to boxwood, though a little softer. Locally it is used for making native combs. There is also a so-called Leopardwood, termed Koligi by the Mendis, which has a curious striped grain a little reminiscent of a leopard’s skin; hence the name. The local inhabitants have various chewsticks, which are obtained from guttiferous trees or Vernonia species. Carapa Gayensis is found and used locally both as a timber and also the seeds for making an oil for the skin. In connection with all this local felling it should be noticed that there is scope for sawn timber of all kinds, more especially when it is taken in conjunction with the fact that over 2,000,000 feet board measure of planks, etc., are imported every year. A small mill placed near Bureh Town would probably be able to supply all wants as far as Freetown and the immediate neighbourhood were concerned, and water power might be available from the Gumah River, which flows down very rapidly to the sea. A mill, on the whole, is more economical in conversion than the local sawyer, as all slabs are left to rot in the forest, but these a mill would consume in power-making, or they would be resawn into smaller boards or shingles. At present there is no sawmill in the whole country, so that there is an open field for this venture, with a forest adjacent to the market and suitable conditions of labour.

IV. Minor Forest Produce.

No account of the Sierra Leone forest would be complete without a description of the two chief vegetable products of the forest, namely Palm Oil and Kernels and Gum Copal.

Turning first of all to Gum Copal, known botanically as Copaifera Salikounda, which is a true copal gum, not to be confused with the gum from Daniellia Ogea and other allied species, illustrations Nos. 8 and 9 show this tree standing in the open, and also the shape of the trunk at nearer inspection. It will be seen that it is rather a tall tree, with open thin crown and straight upward-spreading branches. The bole usually does not exceed 30 feet in length, and then forks or divides into three main stems. The curious marks on the stem, making the tree look as if it were attacked with some form of canker, are those made by tapping the trees for the gum. At the beginning of the dry season small squares of bark, about an inch across, are removed from the tree, beginning at the ground, upwards to 20 and 30 feet. At the corners of each little square gum gradually exudes during the dry season in the form of an ever-increasing sized globular tear, which hardens on exposure to the air. By the end of the dry season, as in February or March, it has attained a size of half an inch or so, and is then quite hard and white and nearly transparent. Only a few little pieces of bark adhere to its surface, and these are easily removed. Then these tears are collected in a bag, sorted, and then sold to the European firms in Sierra Leone and elsewhere. The average tree yields 1 lb. of gum copal per year.

In the peninsular forest a patch of Gum Copal trees is found near Bureh Town. In the Protectorate, irregular belts occur, such as that on the Kassewe Hills and north of Moyamba. On the banks of the Rokell River, too, it occurs in single specimens dotted along the bank. The smooth grey bark of the stem is not unlike Beech, except for the fact that it is pitted by the tapping squares, which occlude only very gradually.

The leaves are in pairs, but have such a straight inner edge that they appear like one leaf which has been cut in half down the middle. The main vein of the leaf is at one side of it. In this manner the leaf is unmistakable, though a Cynometra leaf is somewhat similar, and also a Bauhinia; but in the former the vein is more in the centre and the leaves are quite separate and not close together, and in the latter they are joined at the base. The tree appears to be easily killed by overtapping. Before the formation of the Forest Department, whole forests had been destroyed in this way, one of which I saw north of Moyamba during an inspection of the Gum Copal belt.

The timber of this tree is a red-brown colour, of hard texture, with a pretty grain. It is, of course, of the type of purple-heart. It is very durable and termite-proof, though a borer attacks it slightly. The wood of trees killed by overtapping proves to be quite sound and useful for any purpose where a hard timber is required.

The tree can be grown from the flat, round, paper-like seeds, which are bought at £1 a bushel in Sierra Leone. The tree usually bears well, and the seed is collected off the ground. Young self-sown seedlings are found, which shows that the seeds germinate readily too. It does not stand transplanting very well, but with care soon recovers. It grows rapidly, and reaches a tapable size in ten years, approximately. It does not seem very exacting with regard to soil. In the peninsula it grows on rocky soil, and in Moyamba on an alluvial soil.

Recently the exports have decreased, as the following figures show, chiefly owing to the destruction of the trees by overtapping. However, when the forests have recovered, the younger trees have matured, and the trees since planted are in bearing, and an increase may be expected. It is the most valuable, Gum Copal usually being worth 8d. to 1s. 6d. a pound, but if quite clean and white it fetches as much as 2s. 6d. a pound. Its chief use is for varnish-making, though the best grades are used for pharmaceutical preparations. It is far easier to tap than rubber, and the cost of preparation is therefore very low, so that it should prove worth cultivating on a large scale. The market for Gum Copal is a comparatively large one, and other sources of supply, such as those of Kauri Gum from New Zealand, are decreasing, or not entirely meeting the demand. It is only a question of time before the whole supply will have to be obtained from cultivated trees.

It stands a certain amount of shade during the first four years, but from the fifth year onwards it is distinctly a light-loving species. On the whole it is almost a gregarious tree, as usually groups of trees are found up to fifty or more, and in a whole forest the prevalent tree will be Gum Copal; for instance, in the Gum Copal belt near Susuwuru. A planting distance of 6 feet will probably prove advantageous, as the tree has a distinct tendency to branch low down on the stem if not forced to grow up straight by the presence of other trees. Then in the tenth year a judicious thinning out of the weakest trees by tapping to death would give additional space to the others and allow for greater girth increment for the other clean-stemmed trees. An early financial yield would also thus be obtained.

In the economy of the country, more important even than the Gum Copal is the Oil Palm (Elæis Guineensis), which is found in the Forest, scattered in groups and belts amongst farms inland, as at Blama, and near the sea coast, as at Sherbro, and also as isolated individual trees in the drier parts of the Protectorate. Towards the northernmost part of the country it is not seen at all, though climatically there is nothing to stop it growing if planted in suitable localities. It tends to spread with increasing cultivation of the ground, so long as the rainfall is sufficient and the soil moist enough for it. In the forest itself it is very sparsely distributed. Owing to the large population and the comparatively small area on which the Oil Palm is really plentiful, more palm oil is eaten than exported. This is most clearly seen in the quantity of exports of both products, which show a much larger proportion of kernels than oil.

The fruit usually ripens in January, February, March, or sometimes earlier, and is left for six months. Usually the trees have to some extent been cleared by the natives, then on a certain day the bunches of fruit may be cut. This takes place after the natives have cut the bush down for making the chief’s farm. It also ensures, incidentally, that most of the fruit is quite ripe, though this is not the reason why the natives may not begin cutting off the bunches when they like. The bunches of fruit are left in the forest at convenient places at the edge of the path, covered with palm leaves. After a week or so these are taken to the village, and all the drupes cut off with a machete. These are next put in large earthenware pots with a little water, which are then placed over a good fire. In about an hour the fruit is thoroughly steamed. The fruit is then piled into a trough of beaten clay with a palm-nut bottom, or even stones. Water is poured in, and the fruit is pounded with the feet and also with a small pestle. The oil gradually rises in yellow fatty masses on the surface of the water, and is collected with the hand and put into a clean pot. As soon as a pot is filled, it is placed over a good fire to boil. When it has been boiled thoroughly it is strained, the strained oil being that usually eaten or sold to firms for export. The residue of dirt and pieces of fibre is used as an illuminant in the native lamps. The nuts are placed in the sun to dry for two or three months, after which they are cracked with a stone or a piece of iron and the kernels collected in boxes or bags for sale. The fibre in the washing trough is thoroughly squeezed by hand and all oil extracted. The water is let out of the trough gradually, and all oil collected from the sides of it. It is also washed down with water to collect the more adhesive particles. Even so, there is a large percentage of waste. An oil is also made from the kernels by heating them in an iron vessel over a fire. This oil is used for the skin or for wounds.

In the ordinary way oil palms are not planted, though in moving to a new area where farms have not been made before the natives take oil-palm fruit with them, which get scattered as nuts; these germinate and form the nucleus of a group of oil palms in that locality. Considering the large population and its increasing need for the oil, the planting of oil palms appears to be remunerative.

Palm Wine-tree (Raphia vinifera) is used very largely where it is found in the extensive forests near the rivers and sea coast in swampy places. Piassava fibre is obtained from this source, but so far has not been used in Sierra Leone for this purpose, whereas in the neighbouring country some of the best piassava is obtained. The people are, however, otherwise occupied, so that until there is a greater population it is unlikely that this industry will be taken up. The approximate area of wine palms is 3,000 square miles in various parts of the whole country. Some of the best areas are found on the banks of the Mano, Morro, Maho and Rokell Rivers. The long fronds of the leaves yield the steering and pushing poles for canoes, also most useful rafters and scantlings for houses. The leaves themselves are made into mats for covering the houses. They are said to last seven years when properly put on. The fruit of the tree is used for stupefying fish, which can then be very easily speared by the natives. The tree is usually set on fire to draw the palm wine, though this more often happens subsequently to the taking of the wine. A tree does not last more than three years with severe tapping, such as it is subject to by the natives.

Borassus flabellifer (Fan Palm, Bottle Palm) is found in the northern, drier part of the Protectorate, but so far is not used to any extent for house-building, for which the timber is most suitable, being very durable, of good length, and can be split. The nuts of the large coconut-like fruit are useful as a substitute for vegetable ivory, though thus far no use has been made of them. The approximate area of distribution of this species of tree is about 4,000 square miles. Quite a trade is done in various kinds of bark, altogether from about fifteen different species of trees, of which most are collected in the Peninsular Forest. Amongst them is found the Sasswood, or that of Erythrophlœum Guineense, the notorious native poison, though it is not at all certain that nowadays in Sierra Leone it is used for this purpose.

V. The Forest Department of Sierra Leone.

In the course of 1911 a Forest Department was formed by the appointment of a Conservator of Forests; this has been gradually enlarged until there are now three Assistant Conservators of Forests as well. The chief work of the Department so far has been the drafting and passing of a Forestry Ordinance in 1912 and the demarcation of two Forest Reserves. The Peninsular Forest, with its new boundaries, comprises 75 square miles, and the Kassewe Hill. Other areas have been set aside, notably the Kagnari Hills and Kambui Hills as Forest Reserves, and Nimmini and Loma Forests examined previous to demarcation with a view to their reservation. The Gum Forests were closed to tappers with the consent of the chief, so that the trees could recover from previous overtapping. In addition to this work, some rubber planting has been done in the Gumah, and one Assistant spends all his time on this work, nurseries having been formed in different places—Mano, Bo, and Falaba. A large number of botanical specimens of the trees and shrubs have been forwarded to Kew for identification, so that gradually the silvan vegetation is becoming known. No planting of oil palms (Elæis Guineensis) has been undertaken yet, despite the large export of this product. Rubber planting has not been forgotten either. So far very little revenue has been received for timber-felling fees, which means really that in the past the forests have been destroyed, and now only small quantities can be cut. It does indeed make one pause and think what immense forests must have existed in the days of 1827, when so many loads of timber were exported, as shown in the table on p. 64. If those forests had been preserved then, they would be yielding high returns now, and the Department would be self-supporting, instead of having money invested first in plantations before returns are obtained. However, now that the Department has been formed, a definite Forest Ordinance has been passed, under which Forest Reserves can be made, and the future of the existing forests is thus assured. Sooner or later all of them will yield a monetary return, besides benefiting the country climatically and preserving the soil.

One can really look upon Forestry as a kind of Endowment Assurance, with returns which may begin at once with existing forests, or later with afforestation begun now. The return is always sure, more especially now, with continually rising timber prices. In Sierra Leone, of course, for some years money will have to be put into Forestry work before adequate returns can be made, owing to the reckless mismanagement of the forest in the early part of the nineteenth century. For the purpose of easy reference, a list of some of the most important timber trees is appended, and with both the Mendi and Timani names, when it is possible to give these, and an English equivalent is also given where one uses a name suggestive of the use of the timber.

So far the Department has not leased any areas for the exploitation of timber for export or local use, though there are several areas available, such as the peninsular forest. Even an organization of the sawyers and boat-builders would be a useful work, and machinery for cutting the various woods would lead to greater production and a saving of timber, of which so much is now wasted. Again, the enormous demand for firewood in Freetown, most of which is waterborne, could be more advantageously met with a small sawmill or movable plant in connection with the other wood-using industries already named. The mangrove swamps would provide material ready at hand for conversion. The railway requires firewood at certain points; there again is scope for improved methods of dealing with it, yielding profit both to the contractor and to the Forest Department.

Parkia sp. Gumni (Mendi).

The tree is much like the P. biglobosa, but is found growing wild in the forests. It differs in having well-developed buttress roots. The seed is not eaten.

Lonchocarpus. Mountain Mahogany. Ali (Timani); Jumbowill (Mendi), probably Peltophorum sp.

A very tall and straight tree, with a bole of 50 feet and a girth of 10 feet. It is found everywhere, especially on the edges of old clearings and in old farms. It has been felled for export, but no data are available as to its worth. The wood resembles pine, being soft and full of resin-like canals.

Lonchocarpus cyanescens.* Big-leaved Indigo. Jalei, Walwei (Mendi).

A valuable dye is obtained from the leaves, which takes the place of indigo and is sold at from 4s. to 4s. 6d. a pound in England.

A branched and gnarled tree growing on the sea shore, its roots often being washed by the tide. The timber is close-grained, hard and durable.

Cassia Sieberiana.* Bongbo or Bangbwei (Mendi).

A small tree bearing handsome yellow flowers. A decoction is made from the root to ease elephantiasis, also stomach troubles.

Copaifera Guibourtiana.* Sierra Leone Gum Copal. Akak (Timani); Kobwi (Mendi).

This tree was found growing on the ridges and low-lying land near York and Bureh Town, also in Ronietta, Karene District, and Kassewe Hills. It is noted for its gum. The dead wood works up very well, having a fine grain and red colour, and should be of value for export. Locally it has only been used for bridge-building. The average price paid by local traders for the gum appears to be 1s. a pound.

Copaifera salikounda.* Buini (Mendi).

A large tree.

Pterocarpus esculentus. Atont (Timani); Batwi (Mendi).

Pterocarpus erinaceus.* Rosewood. Katai (Timani); Bundwi Batwi (Mendi).

This is a small but valuable tree, confined principally to the drier parts of the country, particularly in the Karina forests. The wood finds a good market in France. Locally it is used to make a musical instrument called “Balangi.” The seeds are intoxicating when eaten raw.

Macrolobium sp. Jamostima (Mendi).

Macrolobium Palisotii. K’Pal (Timani); Bumbi (Mendi).

Macrolobium sp.?* Limba? African Violet Wood. Tunfall (Timani); Pfandi or Mbombi (Mendi).

CHAPTER IV

LIBERIA

I. The Gola Forest.

This comparatively narrow strip of Africa, extending from Cape Palmas on the east to the Mano River on the west, an area of 40,000 square miles, is a Negro Republic under the nominal protection of the United States. It is bounded on the west by the British Colony and Protectorate of Sierra Leone, and on the north and east by the French possessions of Senegal and the French Ivory Coast.

Some years ago a large rubber company was formed to exploit the wild-growing rubber vines and trees, and until recently fairly large amounts were secured. Apart from rubber, however, there are large forests, one of the best being the Gola Forest, on the western boundary and contiguous to the Sierra Leone Protectorate.

This Gola Forest is formed by the confluence of the Morro and Mano Rivers, being thus triangular in shape and approximately 250 square miles in extent. No natives actually live in it, though there are a few villages at the edge, such as Yandahun and Dambarra. The typical forest is seen in the view of the River Morro near the junction of the Mano. Here herds of elephants roam and make tracks through the dense growth of numerous trees; in fact, the only paths there have been made by the elephant. The Chief of Tunkia always has at least ten youths with him learning the art of elephant-hunting, for which a large fee for tuition is paid. In illustrations Nos. 10 and 12 views of the inner parts of the forest are given.

II. The Most Valuable Trees.

The chief species of trees suitable for cutting for export are the following:

1. Mahogany (Khaya ivoriensis), probably, a very well textured wood with some very pretty medullary rays and a thorough sheen on it when planed. Illustration No. 13 shows a specimen of this tree.

2. Satinwood (Afrormosia laxiflora), a large tree with smooth bark, which varies from light green or yellow to an orange-red shade, thus making it very conspicuous in the forest. See illustration No. 11, which shows one of these trees of medium size.

Fig. 10.—Large Brimstone Tree (Sarcocephalus sp.), Gola Forest.

Fig. 11.—African Satinwood (Afrormosia laxiflora). Gola Forest.

To face p. 66.

3. The African Oak (Oldfieldia africana), Paulai of the Mendis is more common in the southern than in the northern part of the forest. It attains a large size, but has not yet been exploited either by a European or a native firm. This is one of the most durable of African timbers. As it has already been described in the chapter on the Sierra Leone trees, further notes on this tree are unnecessary here. Illustrations Nos. 5 and 6 show this tree to advantage, especially its straightness of growth.

4. The real Satinwood (Zanthoxylum macrophyllum), not an uncommon tree, of small size. It is most easily recognised by its very long pinnate leaves. One leaf may attain a length of 6 feet. There is another species of Zanthoxylum which also has a similar kind of timber.

5. African Walnut (Lovoa Klaineana). This tree is not very prevalent, but is scattered in small groups throughout the forest.

6. Cedar Mahogany, a species of Guarea which attains a large size. It is none too prevalent, though it is scattered singly throughout the forest.

7. African Pearwood (Mimusops lacera) is a very good reddish timber, often with figure in the grain. Although much harder than mahogany, it has been sold as such.

8. The Iroko (Chlorophora excelsa) is common near the old farms, but is not so prevalent in the forest proper. It has not yet been exploited from here, nor is it cut locally.

9. The Red Ironwood Tree (Lophira procera) is very prevalent, and attains much the same size as elsewhere. It has not yet been exploited.

10. The so-called Mahogany, the timber of a tree, a species of Parinarium, known as Pauwilli of the Mendis. This is one of the most prevalent trees in the forest. It is also somewhat gregarious, as many as forty specimens being sometimes found in one group. The timber of this tree was exported from Southern Nigeria some years ago. It grows to a height of 150 feet, with a clear bole of 60 feet in height, and upwards of 18 feet in girth. Illustration No. 2 shows the trunk especially, and the base of one of these trees. A most typical scene in the northern part of the Gola Forest is shown in illustration No. 12, several of the trees in that picture being Pauwilli.

All the above-mentioned trees have been cut and exported in the log from various parts of Western Africa. There are, however, several other trees which might be cut and used as export timbers, as, for instance:

11. The White Mahogany (Canarium Schweinfurthii), which attains the same size as elsewhere, but is not so commonly found.

12. Rhodesian Mahogany (Afzelia bracteata?), which is fairly common and attains a medium size.

13. Brachystegia spicæformis, which yields a light-brown hardish timber with very pretty grain. (See illustration No. 104, which shows a very large specimen of this tree in Nigeria.) It is very prevalent, in fact one of the commonest trees in the Gola Forest, so that large quantities of timber could be obtained.

14. Wismah (Sierra Leone name) is also found, and apparently grows up very quickly in old farms.

15. The Red Oak (Berlinia auriculata) is quite prevalent, especially near the banks of streams. It attains a large size, and the timber has been sold as oak in the European market. Here it has not yet been cut.

In addition to the trees which can be felled for conversion into export timbers, there are others which may be cut for sale locally, such as:

16. The Brimstone (Morinda citrifolia?), one of the most suitable trees for the purpose. One of the largest trees was 5 feet in diameter, and had also a clear bole of 50 feet. On the whole it grows to a larger size in the Gola Forest than in Sierra Leone. Illustration No. 10 shows one of these trees from which a timber specimen had been cut.

17. The Hamon, which is apparently a species of Sterculiaceæ, although not of enormous size, has a straight bole, which divides up into four or five very large and thin root flanges. It is one of the most prevalent trees in the forest. Illustration No. 14 shows the peculiar formation of the roots of this tree.

18. Piptadenia africana, a very large tree with small and fine pinnate leaves. It is frequently met with, in fact one of the commonest of the trees in the forest. It yields a hard brown wood which is durable.

19. The so-called Mountain Mahogany, probably a species of Leguminoseæ. It attains a large size, and yields a timber not unlike that of Red Pine.

Up to the present no local or other sawyers have worked in this forest. Although only a few trees have been mentioned which could be cut for use locally, there are many others out of approximately a hundred different kinds which are found in the forest.

There are other products, such as oil beans, obtained from Pentaclethra macrophylla, a large forest tree; gum copal, obtained from Daniellia Ogea, one of the largest forest trees; palm oil and kernels from the Oil Palm (Elæis guineensis), which is found in all the clearings. Piassava, obtained from Raphia vinifera, is found on the banks of the two rivers, Morro and Mano. Rubber could be obtained from the African Rubber Tree (Funtumia elastica) and various rubber vines, such as Landolphia Owariensis, and others. Dika nuts could be procured, as the tree which bears them, Irvingia Barteri, is commonly found; also the Tallow Tree (Pentadesma butyracea), which bears a large number of oil-bearing nuts in its large fruit; the Dita (Detarium Senegalensis), which yields a mango-like fruit, eaten locally. Bitter Kola (Garcinia kola) is found, but not often sold in the local market. The rough-skinned Parinarium excelsum yields a fruit which is eaten locally; the African Star-apple (Chrysophyllum Africanum) is found in the forest, and also planted. In other villages the Akee, being obtained from Blighia sapida, is quite common in the forest, though the edible fruit is not used. The Mackay or Sea Bean (Entada scandens) is a huge creeper which grows to 350 feet in length and 3 feet in girth. Near Dambarra, from a stout specimen hung a complete pod containing fourteen beans.

III. Conditions of Working Timber.

The Mano or Bewa River forms the natural outlet for the extraction of timber, as the Morro River forms one boundary of the Gola Forest, and this river joins the former rather more than half-way through the forest. The Mano River reaches the sea about 80 miles from the end of the forest; thus logs of timber could be brought down the Mano straight into the sea.

Very good timber of various kinds of mahogany has been shipped from several ports, such as Sassandra and Grand Bassam on the Ivory Coast. Good prices, such as 1s. to 2s. 3d. per superficial foot, have usually been paid for this timber. There is therefore no reason why similar timber from Liberia should not fetch equally good rates, when properly cut, squared, and sold under similar conditions.

Conditions of working are very similar on the West Coast of Africa, but may vary somewhat in detail from place to place. However, if at the outset natives accustomed to working timber in Nigeria or the Ivory Coast were employed, good results would be obtained. Gradually a local native staff would be built up, so that the services of those from another part of the coast could be dispensed with and cheaper working thus assured; because imported labour, whether skilled or otherwise, is usually more expensive than that of the locality. Lower shipping rates should be paid from Liberia than from the Ivory Coast or Gold Coast, owing to the distance being less to the European markets where the timber is sold.

The other forests of Liberia should be thoroughly examined to see what amount of timber is there. It is usual to work several areas in conjunction, as the cost of management per unit of output (the log) is thus reduced.

A large but slow-growing tree, with a hard, prettily grained wood, rather uncommon.

Garcinia sp.? Mahogany.

The wood sometimes sold as mahogany.

Garcinia sp. Chew-stick.

The smaller roots are used as chew-sticks, but taking these in the drastic method in which it is done generally means death to the tree. It is found on summits of the mountains.

Flacourtiaceæ.

CHAPTER V

THE IVORY COAST

Thanks to Monsieur Auguste Chevalier’s very varied and extensive travels on the Ivory Coast, we have obtained very graphic descriptions of the belt of forest extending nearly 150 miles inland and parallel to the coast.

In his books Les Végétaux Utiles de l’Afrique Tropicale Française, Fasc. V., Première Etude sur les Bois de la Côte d’Ivoire, and Les Végétaux utiles de l’Afrique tropicale française, Fasc. VII (Première Partie), Documents sur le Palmier à Huile, on the vegetation of this French Colony, not only are there general descriptions of some of the best and most accessible forests, but also there are full descriptions of the individual trees, together with most of their botanical and most valuable vernacular names.

Considering that the area of the Ivory Coast is 130,000 square miles, and the forest belt about 150 miles wide, the mahogany industry should be still further developed than it is at the present time.

So far, on the average, the Ivory Coast has been noted for its figured mahogany, the Ports of Grand Bassam, Assinie (a town and river of Upper Guinea), and La Hou being the most noted, and having given almost their name to different classes of Ivory Coast mahogany. For several reasons this type of mahogany has fetched higher prices than that of the average from elsewhere. Sassandra, at the mouth of a similar named river, and also Cavally, on the Cavally, are minor ports for the shipment of mahogany.

First and foremost the wood obtained from what Monsieur Chevalier terms Khaya Ivoriensis is of a much more sheeny nature than that of either Khaya Senegalensis, Khaya grandis or Khaya Punchii.

In the next place, the method of working is most peculiar. Usually, individual natives cut a few trees at a time, standing nearest a waterway or lagoon; in fact, these were picked trees which the natives thought contained figured wood, and this had the effect of only a one-sided working of the forest, thus leaving many other valuable trees. On the average, the distribution of the numbers and of the various species is about the same as in other parts of West Africa. Apparently many of the ordinary trees have often been left standing, or at any rate most of those which are too inaccessible. A tree standing more than about a mile from water is too far for a native working almost single-handed, and only collecting a few labourers for hauling his logs to the waterway.

In recent years, however, British as well as French firms, with a larger amount of capital, have started to work the forests. Regulations have been drawn up by the local Government in a similar manner and of a similar nature to those in force generally on the West Coast of Africa. The Government also has built a railway passing through and near some of the forests north of Grand Bassam. Since its inception, a further impetus has been given to the mahogany trade. However, in the matter of water transport, the rivers of the Ivory Coast, such as the Tano, mostly flowing in British territory, but emptying itself into the sea at Assinie (the port for logs in French territory), the Yar or Abi, the Komoe, the Zini, and Bandana, the Sassandra and Cavally, can none of them be said to be at all good for the floating out of logs. La Hou is the port for the Bandana and Zini Rivers, after their junction; Sassandra is the port for the Sassandra and Cavally for the Cavally. At the mouth of each of them there is a shallow bar, and this in turn causes a bad surf, and in other parts the coast lacks harbours, and the formation of it is unsuitable for the shipment of timber. No doubt, as time goes on, an effective means will be invented for dealing with the passage of the logs through the surf, especially at the mouths of rivers. So far, from all accounts, the rivers themselves have not been cleared of snags and rocky obstructions for the transport of the timber. This factor again has reacted on the output, and many of the finest forests remain unworked. Owing to the fact of this accidental policy of only cutting the best mahogany trees, the intensive exploitation of the forests by cutting other species of trees (the timber of which has already found a market in Europe) has been greatly hindered. Among such timbers are the following:

- Khaya Ivoriensis,
- Chlorophora excelsa,
- Lophira alata,
- Afzelia microcarpa,
- Entandrophragma macrophylla,
- Canarium Schweinfurthii, or Occidentalis.

On the whole, English firms working on the Ivory Coast have been encouraged and not hindered, but some of the minor regulations appear to be rather irksome and vexatious in their working, and the firms have felt that their tenure of the forest rights was not quite so secure as elsewhere in West Africa.

The export duties placed on mahogany cut on the banks of the Tano in Gold Coast territory are almost of such a nature as to prohibit the profitable working of the Tano forests.

CHAPTER VI

THE GOLD COAST

Area, 80,000 square miles.

During 1909, a most interesting and exhaustive Report on the Forest of the Gold Coast, as well as Ashanti and the Northern Territories, was written by Mr. H. N. Thompson, the Chief Conservator of Forests of Nigeria. As a result of this Report, a Forest Department was formed in 1910. This Forest Department now consists of a Conservator, Deputy, and three Assistant Conservators of Forests. However, legislation for the proper preservation of the forest and creation of Forest Reserves has not been passed, so that the scope of the Forest Department’s usefulness has been much curtailed.

It would be quite superfluous here to try and describe the forests in such a masterly fashion as has been done by Mr. Thompson, but anyone who is interested in the Gold Coast Forests should read the Report for themselves. It will suffice to give an outline of the main features of the Forest Administration and a general description of the forests.

With the author’s permission I have given a list of the timber-trees, together with the botanical names, so far as they are known.

The people of this very rich country have in a short-sighted way very much hindered real progress in Forestry by refusing to assist in the creation of Forest Reserves. Forest Reserves are, of course, simply forest permanently set aside for the production of timber or other such forest products. The people of the Gold Coast have, apparently, judging by extracts from the local Press, got the idea into their heads that the making of a Forest Reserve necessarily means the ownership of the land on which the forest stands passing into the possession of the Government. This, of course, is quite a contrary view to the true conception of a Forest Reserve, which is an area set apart by the Supreme Government as a forest for the permanent production of timber, etc., and usually managed by the Forest Department of the country. It may be a State forest, a communal forest, a municipal forest, or even a private forest which is thus placed under Forest Laws as a Forest Reserve. The user (that is, the man who has the right of usufruct in it) is not generally in a position to protect it thoroughly, and to some extent foregoes present temporary profits for future permanent returns.

The diverse forms of forests named above, under the permanent management of the State, are seen in Switzerland, Germany, France, Russia, Japan, and India, not to mention Nigeria, so that it cannot be called an isolated system.

The cocoa industry has quite overshadowed that of collecting palm fruit, making palm oil, and cracking of palm nuts to obtain the kernels, with the result that these exports are small compared with Sierra Leone even, which is a much smaller colony, with a climate less propitious for palm-trees.

The following table shows the exports for the last five years:

| Tons. | £
1909 | 14,553 | 113,784
1910 | 14,252 | 185,058
1911 | 13,254 | 175,890
1912 | 14,629 | 205,365
1913 | 9,744 | 159,128

In the year 1913 forest produce, in the shape of logs, etc., to the value of £3,327,743 was exported. It would be disastrous to the country if a few loud-voiced, narrow-minded people were to prevent proper measures being adopted for the welfare of the country. Considering their previous education and small experience in these wide economic matters, it is only natural that they should take this view, but, on the other hand, that is no reason why the Supreme Government should not do what is necessary for the future permanent benefit of the country. A child is not allowed to play with fire, although it may very much like to see the flames; in the same way the British people, as locally represented by the Gold Coast Government, cannot allow the inhabitants of the district to play fast and loose with their priceless treasures, the African forests, well knowing that the country will be permanently injured thereby. Examples are to be found to-day of countries which have allowed their forests to be destroyed. Spain and Portugal are typical of this, and even in Africa one has the spectacle of France putting untold millions into Forestry in Algeria in order to restore the rainfall. Morocco and Mesopotamia are further examples of countries in a similar condition, where the forests have been destroyed. Palestine, with its ancient forests of Lebanon, is the most drastic example of forest destruction, quite apart from Turkish misrule. A similar process has taken place in the Soudan, and this locality is only now being laboriously re-afforested by the Forest Department there. In India, European countries, Canada, Australia, and in the United States it has been proved that it is only by a central Government Agency that the forests will be properly preserved both for this generation and the next; therefore, before it is too late, it behoves the Gold Coast people to recognise their responsibility to future generations and allow the necessary legislation, so that the forests may be preserved and rightly utilised.

CHAPTER VII

TOGO

Introduction.

During the latter part of 1911 I had the opportunity of visiting Togo. Since August 1914 it has been in the occupation of British and French troops, administered as a co-dominion.

Forest Station work has been the main work of the Forest Department since the inception, both under the District Officer and subsequently under the trained officer. There is only 1 per cent. of forests in the whole country.

Lome, the capital of Togo, formed my starting-point, and there His Excellency the Governor and the Secretary of the Colony advised me as to the best route and supplied me with many interesting details as to the system of taxation, etc.

Taxation.—In Lome every man above sixteen years of age has the choice of paying 6s. per year or working twelve days for the Government. On the coast it is found that the natives prefer to pay the tax, but inland the twelve days’ work is usually given. This Government work consists of plantation and road making, bridge-building, erecting rest-houses, and many other kinds of public work.

The subject may be divided into three sections:

(1) The Forests between or at the Stations.

(2) The Forest Department Plantations.

(3) District Plantations.

I. The Forests between or at the Stations.

Near Lome the ground is very sparsely covered with thorny shrubs and occasional Baobabs, Adansonia digitata, but on nearing the valley of the Schio the soil improves and small plantations of sugar-cane appear. Though no attempt has been made here to develop this industry, the natives of Tagblekovke and other places sell large quantities of the cane. Oil palms are seen on both sides of the line, chiefly, however, on the river banks, owing to the annual grass fires. Scattered silk cotton-trees also occur along the river banks, otherwise only the normal dry-zone vegetation is found.

The rainfall, however, is quite sufficient for the growth of a deciduous forest. The remains of fringing forests on the banks of the Rivers Schio, Lili and Haho consist of Pterocarpus erinaceus, Erythrophlœum Guineense, Terminalia Togoensis and a few specimens of Afzelia or Cynometra.

Passing on to the Haho-Baloë district, plantations occur at the junction of these rivers in an open plain of scanty dry-zone forest. A fringing mixed forest of the normal type, varying from 200 to 500 yards in width, was found on the banks of each river, and as it formed a complete fire protection, was left untouched. In the open forest the most common trees are the Pseudocedrelas, Pterocarpus erinaceus, Butyrospermum Parkii and Terminalia.

The rainfall varies at this spot from 28 to 39 inches annually. The higher rainfall is probably the true average, if considered in conjunction with the natural vegetation. A great change in the vegetation was noticeable between Nuatjä and Atakpame; the typical dry-zone trees, such as Pterocarpus erinaceus, Shea Butter, Lophira and others, were soon left behind, and on nearing the hilly country of Atakpame a more flourishing condition was evident. Oil palms were growing in profusion both on the banks of the rivers and also on the sides. Large cotton-trees, Triplochiton Nigericum, Iroko, Chlorophora excelsa, Sterculia cordifolia and other trees of this kind were seen. The rainfall is much higher here, averaging from 58 inches, spread over the months of April, May, June, July, August and September, and a little in October. This rises to 58 inches, falls to 52, 105 miles to the north of Atakpame, in the Sokode District. This is spread over the usual rainy season of West Africa; more rain, however, falls in September than in the northern part of Southern Nigeria during the same month. After leaving the hills of Atakpame behind, we took the road to Sokode, and between the Rivers Tagbadja and Au the following dry-zone trees were most prevalent: Lophira alata, Shea Butter, Terminalia Togoensis and Pterocarpus erinaceus. As we advanced the Shea Butter Tree ceased, but more Terminalia were seen; Pterocarpus in groups and Pseudocedrela Kotschyi became very prevalent. Fringing forests were seen in the level country which followed along the banks of the Ana River.

On the third day’s march I found a large specimen of Khaya Senegalensis and several smaller ones at a place just above the eighth parallel of latitude, below which the Khaya Senegalensis is rarely found. Beyond this were Paradaniella thurifera, Borassus flabelliformis, Fan Palm, Afzelia Africana and Shea Butter, and less of the species already mentioned.

These were succeeded by small pure forests of Berlinia Kerstingii, Afzelia, Ormosia laxiflora, Bauhinia reticulata, Erythrina Senegalensis, Parinarium polyandrum and Parkia Africana, syn. filicoidea. Nearing Blita rest-house, bamboos appeared, Agave rigida, and also a Ceara-rubber plantation.

It was interesting to find on inquiry that this plantation was the result of 1,000,000 Ceara seeds distributed to the natives in 1907. The vegetation on the banks of the rivers and streams consisted mostly of deciduous forest, with typical dry-zone trees at the edges. In addition, Pentadesma Kerstingii and Dalbergia melanoxylon were seen.

The last-named species has, according to German botanists, been confused with Diospyros mespiliformis, so far as the timber is concerned. The last two miles before reaching Sokode were covered with extensive plantations.

Dry-zone Trees.—Between Sokode and Bassari, a distance of 37 miles, are the Malfakassa Mountains, of which the summits are mostly bare, owing to the annual grass fires, but a dense growth of Berlinia Kerstingii, Terminalia and Afzelia Africana grow in the moister valleys.

On the more open ground the usual dry-zone trees were seen, and the Khaya Senegalensis on the banks of each of the four rivers.

The rainfall is the same as that of Sokode, about 52 inches, although the atmosphere is moister, which is partly due to the higher altitude.

The somewhat cooler temperature of the air causes heavy dews, and these also, in their turn, increase the moisture of the air. The differences are thus very marked between Sokode and Bassari as to the atmospheric moisture, and also as to the variation in the growth of the trees at the two stations.

After a short visit of two days I left Bassari for Jendi, 70 miles to the north-west. One range of hills on the way is noticeable for the pure formation of iron ore which “crops out” and causes the tree-growth to be small.

The vegetation becomes very sparse towards the valley of the Oti, 30 miles distant from Bassari, and this is owing to a great change in the climatic conditions as compared with Bassari, as well as the annual grass fires. The sole representatives of the dry-zone vegetation, which, near Bassari, had originally consisted of Khaya Senegalensis, Afzelia and Shea Butter trees, are the Baobabs, Adansonia digitata.

The rainfall is only 43 inches per year. The poor vegetation found near Jendi gradually gives way, between that station and Kete-Kratschi, to more typical dry-zone trees, such as Shea Butter, Lophira, Afzelia and Berlinia Kerstingii.

Oil palms were found on the third day growing near the banks of the streams, and more Afzelia in the open country. Mimusops multinervis and Diospyros were found near the River Volta, at the edge of a wide belt of evergreen forest.

The dry season is much prolonged in most years. On the average the rainfall is 46·8 inches. At the next station on the tour, Pfandu, the rainfall rises to 55 inches per year. Near the summit of the station hill the soil is poor, but excellent on the lower slopes.

The climatic conditions of Pfandu, a substation to Misahöhe, are unfavourable, and labour is less obtainable. The road between these two stations passes through very poor dry-zone forest, but on entering the Misahöhe mountainous region we came upon a fine evergreen forest. The most common trees noticed were Khaya Klainii, Mahogany, Iroko and Terminalia superba, the shingle-wood tree, also Triplochiton, Sterculia cordifolia, Carapa procera, Piptadenia Africana, Pentaclethra macrophylla, Detarium Guineensis, Brachystegia spicæformis, Berlinia acuminata, Afrormosia laxiflora, Satinwood, Alstonia Congensis, Ricinodendron Africanum and Eriodendron Nigericum. The mahoganies of this district were remarkably fine trees, mostly over 10 feet in girth.

A written permit, costing 3s. per tree, has to be obtained for cutting trees, and also permission from the Commissioner, before forest land may be cleared.

The high rainfall of Misahöhe, which is 62 inches per year, produces a very moist atmosphere.

After a visit of three days to the Misahöhe Station, I left for Palime, the terminus of the Lome Railway. On the way down the mountain, the contrast between the eastern and western slopes was very noticeable, a deciduous forest covering the eastern slope and an evergreen forest the western. For the first 10 miles from Palime on the way to Lome, mahoganies, oil palms and other trees abounded, but gradually gave way to the same drier type of forest as that seen on the Nuatjä railway-line.

This condition of vegetation continued until Lome was reached, a distance of 75 miles.

II. The Forest Department Plantations.

During 1907 there was a Forestry Conference in Berlin with regard to the afforestation of the Colony of Togo (which is wooded only to the extent of 1 per cent.), with the result that the area of Haho-Baloë was first chosen, and the plantation started at the junction of the rivers.

A fringing mixed forest on each bank of the river was left untouched, as they formed a fire protection for the plantation. Pseudocedrelas, Pterocarpus erinaceus, Butyrospermum Parkii and Terminalia were the most common trees found in the open forest between the rivers.

The altitude of this area above sea-level is about 480 feet. It slopes slightly from north to south and is triangular in shape.

Seedlings were first tried, but did not survive the first season, and since that time seeds have been sown, and this proved a great success. Eight species of trees have been used to form these plantations:

- (1) Teak, Tectona grandis.

- (2) Afzelia Africana, also called Rhodesia Mahogany or Apa.

- (3) Sasswood, Erythrophlœum Guineense.

- (4) African Mahogany, Khaya Senegalensis.

- (5) Khaya Klainii, Mahogany.

- (6) Iroko, Chlorophora excelsa.

- (7) Kapok, Ceiba pentandra.

- (8) Anogeissus Leiocarpus, Chew-stick Tree.

One-sixth of the total area, however, has been planted with teak; in all, 491,300 seedlings. The Erythrophlœum seedlings are most numerous, the wood of this species being hard, durable and termite resisting. It has been used with great success for piles and trestles in bridge-building.

Afzelia and the two mahoganies will be valuable and useful timbers, especially the mahoganies, as they are indigenous to the country, and there is not the element of speculation attending introduced trees.

In addition to the eight chief species named above, a few specimens of Detarium Guineense (the Dita fruit of Sierra Leone) and Cynometra were planted, but their growth is slow. A mixed crop, consisting of Parkia filicoidea, the Locust Tree, Prosopis oblonga, Anogeissus leiocarpus and Detarium Guineense (Senegalense), has also been planted.

The mixture is a good one, but the growth has been slow. The general appearance of the area where teak has been planted, in spite of the fact that the bush was left standing, is that of a teak plantation, for the teak has outgrown all the indigenous trees and formed a complete thicket.

Owing to the lack of drainage in the soil, as well as attacks of the borer, the Khaya Senegalensis has grown slowly. Slow growth is noticed also in the Apa, Afzelia Africana, but that seems to be typical of the tree.

During the first year the cost of planting (including building and labour) worked out at £4 4s. an acre, but by the third year this amount was reduced to £1 2s. The valuation of the whole plantation is at least £10,000.

The second Forest Department’s afforestation area is Mo-Kamaa, which is being planted in a similar manner and with similar planting methods to the area situated near the Haho-Baloë. Tax labour has been used to a large extent in these plantations. The situation is particularly suitable for planting operations, owing to its being protected on two sides by the rivers from the annually recurring fires of this locality. The altitude is about 500 feet above sea-level.

As in the case of Haho, nurseries were made for oil palms only, various species being sown in lines, between which the forest growth was left standing, so as to form shade for the seedlings. Approximately 600,000 seedlings have survived, about 400,000 Khayas and 200,000 teak.

Dry-zone mahogany, Khaya Senegalensis, and teak have been planted in addition to the oil palm. The Khaya, even up to 12 feet in girth, is found all over the locality, and near the bank of the Kamaa a few oil palms.

The teak has grown much faster than the Khaya, the average height of the former being 6 feet and that of the latter only 2 feet. The teak seedlings are beginning to outstrip the indigenous trees in the locality.

The mixture of these two trees, as far as can be judged, has been a great success. For, by the persistent foliage of the Khaya falling to the ground at a different period to that of the teak, the necessary protection to the soil, when the teak-trees are leafless, is thus given, and the Khaya (Mahogany) benefits by being drawn up by the quickly growing teak, and in both cases there is less tendency to form strong side branches.

With the advent of the proposed railway, the timber in this locality will be of great value; but even without this advantage the present value is at least £1,000.

The planting scheme contemplated is enormous, and includes an area of 96,000 acres. An actual start has been made with 295 acres.

It is an interesting fact that the mixed plantations in the afforestation areas have nearly all been made by the Forest Department, and the pure plantations by the Commissioners at the District Stations.

Approximately 300 acres are composed of mixed plantations and 256 of pure plantations.

The following mixed plantations are found in the Haho-Baloë afforestation area:

- (1) Sasswood and Teak.

- (2) Sasswood, Teak and Mahogany, Khaya senegalensis.

- (3) Sasswood, Teak and Khaya Klainii.

- (4) Sasswood, Afzelia and Cynometra Afzelia.

- (5) Sasswood and Afzelia Africana.

- (6) Sasswood, Khaya Senegalensis and Afzelia Africana.

- (7) Sasswood and Khaya Klainii.

The most profitable mixture of all these is the teak, Khaya Klainii and Sasswood, though all have something in their favour.

These mixed forests need much attention, as one species frequently outgrows another, one suppressing the other, and the mixture consequently no longer existing. More European supervision is required to remove suppressed or crooked trees.

III. District Plantations.

Avenues of trees suitable for street-planting have been largely made in Lome. The Terminalia catappa (almond-tree) is one of the most useful trees for this purpose; at least 12 feet of the stems are quite free from branches, and thus the trees cannot harbour many insects.

The coconut, though made use of for this purpose, is not so suitable, as it lacks height-growth; the Dracæna also, which does not improve the roadside, and a species of Ficus, probably platyphylla, which loses its foliage in the dry season, are neither of them a success. Near the Government House a large number of Casuarina equisitifolia have been planted; these have flourished well, as they can stand the ocean wind blowing almost continuously at Lome.

In the Experimental Gardens, which are situated 80 feet above sea-level, there are many interesting varieties.

The soil, a mixture of very poor sand with a great deal of iron, is not favourable to height-growth of the teak (Tectona grandis); the seeds, though in great quantities, are small and ill-developed. The mahogany, too, showed poor height and girth growth, the locality was evidently not suitable for it. Other trees that did not seem to thrive were Cedrela odorata, the Cigar-box Cedar Tree, Pithecolobium dulcis, Funtumia elastica, Bread-fruit, Artocarpus incisa, Ficus Vogelii, Borassus flabellifer, Bixa orellana, Acacia catechu, Casuarina equisitifolia, Manihot Glaziovii and Manihot dichotoma; but the oil palms, Elæis Guineensis, and Ficus elastica were doing exceeding well and were of a healthy green colour. Bamboos and the usual tropical fruits had also been planted. The Kapok tree (Ceiba pentandra according to German botanists, and Eriodendron Nigericum according to Kew botanists), which has been planted too far apart, has made very little growth.

Under the guidance of the Director I visited the Agricultural School at Nuatja, 50 miles from Lome. Experimental work of all kinds was carried on here. In the nurseries were to be found Kapok, Ceiba pentandra, cotton and oil palms. In a machinery shed were a cotton gin and press, and husking machines for other seed. Lectures are given early in the year, and as the season advances practical work takes their place.

A great drawback to the extension of the Atakpame District plantations (95 miles from Lome) is the shortness of labour, as the natives pay their tax instead of working.

The main plantations have been made on the east side of the station, on a slope facing south. Teak has been very largely planted here, no less than 25,400 seedlings since 1901, when the work was started. Others are Treculia Africana, African Bread-fruit, Sasswood, Mimusops multinervis, the hard red wood of the Olokomeji Reserve, Kapok, Ceiba pentandra, and Cashew Nuts. A new Piptadenia, named Kerstingii after Dr. Kersting, was tried, but most of the plants died. An avenue of Eucalyptus citrifolia, with its delicate foliage, has developed well and fully deserves mention.

The teak has grown well everywhere, except in a small swampy area, where the trees look unhealthy. The very large crops of seeds during the last three years have caused the height-growth to fall off in comparison with earlier years.

Most of the trees are planted too far apart, but nevertheless, seeing the whole hillside, east of the station, covered with a teak forest produces a very wonderful effect on the mind.

If the teak alone is taken as a basis of valuation, the total value cannot be less than £2,500.

The Sokode District plantations have a great advantage over those at Atakpame, as tax labour has been used almost entirely and the population is much larger than elsewhere. As soon as an experiment with regard to agricultural crops, fruit and forest trees proved satisfactory, plantations were at once made.

The orchards, farms and plantations begin on the south-east slope of the hillside, round the station to the south, finishing to the west and north-west of the office building. The plantations occur between the altitude of 1,000 and 1,260 feet. The variations of soil are very remarkable, from poor laterite to rich loam, from sand to swamp; but it is not to be wondered at, when the large area is taken into account.

As at nearly all the other stations, teak has been the most extensively planted tree, some 81,000 seedlings having been set out on an area of 115·9 acres. Oil palms have also been planted in great numbers. These are set some distance apart to get the full benefit of the sun and develop large crowns and stems. Some of the other species planted are: Khaya Senegalensis, Iroko, Funtumia elastica, Ficus elastica, Ceara Rubber, Para, Hevea Braziliensis, Manihot dichotoma, Manihot heptaphylla and Manihot Pianhyensis. Three or four species only of the following trees: Albizzia Cæsalpinia, including Sappan, Cassia florida, Cedrela odorata, Berlinia Kerstingii, Ceiba pentandra, Detarium Senegalense, Diospyros mespiliformis, Anogeissus leiocarpus, Eucalyptus, Melia azedarach, Morinda citrifolia, Ormosia laxiflora, Parkia Africana, Pentadesma Kerstingii, Poinciana regia, Pseudocedrela Kotschyi, Pterocarpus erinaceus and Aspidosperma Quebracho.

The mixed plantations are not very plentiful, but teak and oil palms have been planted together, though not systematically, and have proved a very profitable mixture, which is worthy of notice here. In its early years the oil palm is a shade-bearing tree, so that the shade of the teak does not hinder its growth. In the oil-bearing season the teak is leafless, which is beneficial to the formation of fruit in the oil palm. The dense foliage of the oil palm kills the adventitious shoots or side branches of the teak, so rendering pruning unnecessary. In the dry season the soil is protected most thoroughly by the evergreen foliage of the oil palm, and its masses of small roots conserve the moisture of the soil, while the wide-spreading roots of the teak allow the surface water to run away. For instance, teak and Iroko are not so suitable a mixture, as they both cast their leaves at the same time, though when planted together the teak tends to accelerate the height-growth of the Iroko, and also keeps it freer from the attacks of the gall bug.

If space permitted, many more instances of the advantage and disadvantage of these mixtures might be given.

Orchards have been largely planted at Sokode too. Oranges, limes, tangerines and Cola vera have done well, and the Spondias dulcis yields very large fruit. The date palms have not yet fruited. Fibre plants, including sisal hemp, and the Panama palms seem to be growing well; fibre for Panama hats is obtained from this palm.

A substation of Sokode, Bassari, was my next stopping place. The station is situated on the northern side of the mountain, overlooking the valley of the River Kamaa. The plantations, with the exception of the Ficus elastica, which is 200 feet higher up, are all planted below the station. The approximate altitude is 1,350 feet above sea-level.

The following species have been most extensively planted: Teak, Oil Palms, Afzelia, Khaya Senegalense, Iroko, Ebony, Kapok, Funtumia, Ficus elastica, Manihot heptaphylla, Manihot Pianhyensis, Aspidosperma Quebracho, Cæsalpinia Sappan and Cassia florida. Large orchards had been made, and these contained tangerines, lemon and many other kinds of tropical fruits; and very fine specimens of Eucalyptus trees showed how suitable this locality was for them.

About 200,000 trees have been planted here within ten years.

Funtumia, when planted with teak, grows well in this area, as the shade of the teak is beneficial to it; but planted alone, the leaves become a poor colour and drop prematurely. The same thing is noticeable when planted with mahogany.

In the case of Ebony, one of the knottiest forestry problems of Europe, viz. that of finding suitable trees for admixture, has been solved. Many of them died when planted pure, but the gaps being filled with teak, the ebony seedlings, put into competition with this fast-growing tree, have been “drawn” up quicker than they would have otherwise grown, and have done remarkably well.

The most northerly station that I visited was Jendi, approximately on latitude 9·30, at an altitude of 640 feet above sea-level. The method of planting was slightly different at Jendi, agricultural crops being grown for three years between the rows of forest-tree seeds, only the oil palms and teaks being planted out as one-year seedlings from the nursery.

Besides these two species, Khaya Senegalensis, Afzelia Africana, Date Palms, Ceara Rubber, and Rambong Rubber have also been planted. Altogether 457,200 seedlings are growing.

As firewood alone is worth 3d. a bundle, timber of all kinds is very valuable in this locality, the teak plantation alone being worth £200.

Kete-Kratschi, the station adjoining Jendi and overlooking the Volta Valley, is a specially interesting one, because it was started by Graf Zech, the late Governor of Togo, who was so desirous of seeing plantations made everywhere. At this station the plantations were first made half a mile away, and these have done better than the later ones planted to the east of the station.

Teak has been largely planted, and considering the poor soil and low rainfall, has done remarkably well. For the first time a parasite in the shape of a species of Loranthus was found growing on the upper branches of two large teak-trees, but no diminution in the growth of the teak was noticeable. Afzelia, Khaya Klainii and Khaya Senegalensis have been planted in large numbers, and experiments made with Albizzia lebbek, Poinciana regia, Acacia catechu and Ceiba pentandra. A few oil palms and Casuarinas have found a place in the plantations. Eight miles from the Volta Valley is the station of Pfandu, situated on an open, isolated hill with a sheer cliff to the east and sloping gradually away to the north-west and south.

The only variation here in the planting system was that Cassada was largely used as an agricultural crop between the rows of tree seedlings, which were put in the year after the Cassada had been planted. Though the Cassada afforded a shade for the young seedlings, the latter did not seem to show sufficient growth to warrant a further trial of the system. The teak especially thrives here, the tree having reached a height of 36 feet and a girth of 14 inches, and these trees have already been felled for house-building purposes. The plantation is valued at £550.

Ceara rubber is now being tapped on a large scale. Sasswood, Erythrophlœum Guineense, Iroko, Oil Palms, and Funtumia elastica have been planted in large numbers, and a few Afzelias, Diospyros mespiliformis and Kapok trees.

The hill station of Misahöhe overlooks the valley of the Chedscho and Agu, with the highest mountain in Togo opposite. The people have means to pay the tax here, so labour is scarce and prisoners are employed in keeping the plantations clean. The altitude of the highest plantation is 1,800 feet above sea-level. Manihot Glaziovii has been planted in greater numbers than any other tree; next comes Teak, then Para Rubber, of which one had been tapped with satisfactory results, Funtumia elastica, Oil Palms, Khaya Klainii, Sasswood and Cola vera. Small plantations of Ficus elastica, Cocoa and Anogeissus leiocarpus have also been made. One curious mixture was seen, Teak and Cola vera; the teak-trees tended to grow much faster, and the Cola benefited by the shade.

The most northerly and the driest stations are Sansane Mangu and Kalangasshi, where I was told 1,037 acres had been planted with Teak, Khaya Senegalensis, Ceara Rubber and Afzelia. It is proposed to form the third afforestation area of 15,000 acres at Kalangasshi.

In smaller quantities are to be found the Locust Bean, Parkia filicoidea, Manihot Glaziovii, Shea Butter, Iroko, Ficus elastica, Oil Palms, Funtumia elastica, Afzelia Africana and Kapok. Some teak and a few other trees had been planted at Bismarckburg, an old substation to Kete-Kratschi, and the same varieties at Ho, a substation to Misahöhe.

I was unable to obtain figures as to the number of trees planted at the above three stations, but teak is reported to be doing well at them all.

In addition to the species of indigenous trees planted, and also introduced, species such as Teak, Tectona grandis, and many others have been planted on a small scale.

Alstonia congensis.

Borraginaceæ.

Cordia Gharaf.

A fair-sized tree known only in one locality. A hard, durable wood used in building. There is no doubt that there are other species in Togo, and so far as the Cordia has been used, it has proved to be a most useful tree.

Ehretia cymosa. Okoni (Kratschi).

Found in the coast regions, growing to the height of 13 to 16¼ feet. Seldom met with. It has masses of white blossoms; the fruit is a berry about the size of a pea. The wood has not yet been proved.

Bignoniaceæ.

Spathodea campanulata. Adadasé (Ewe); Gbetschigbetschi (Atakpame).

A wonderful leafy tree, 97½ feet in height, with wide-spreading crown of foliage, and greyish-green warty trunk. In the flowering time the tree is a mass of crimson flowers—a beautiful sight in the coast woods and on the hill slopes. In Europe it goes by the name of tulip-tree. The buds are filled with a sweet, watery fluid, which the children use as squirts. The wood should be of great service, but does not seem to be used.

Newbouldia lævis. Lifui (Ewe); Akinale (Tschaudjo); Aboboë (Atakpame).

A medium-sized prairie tree, found plentifully also near the villages, where the small branches are used as material for fences.

Crossopteryx Africana. Tyenyeṓlo or Pasau (Tschaudjo).

Crossopteryx Kotschyana.

Found to the height of 32½ feet in the prairies of the coast zone and a few scattered inland. According to the opinion of an importer, this wood is one of the best of Togo. It is clear brown, very hard and heavy, and of fine texture. The natives make shuttles and tablets for the Koran from it.

Adina microcephala. Barā (Tschaudjo).

A tree of 97½ feet in height, growing on the river banks of Sokodé-Bassaris. The wood takes a very high place as to value, but it has a peculiar odour and an oily feeling to the touch. The fibres from the twigs are made into tooth-brushes.

Mitragyne macrophylla. Yŏwi or Togba (Atakpame).

A gigantic tree growing on the swampy banks of streams, with an excellent wood used by the natives for making doors, drums and barrels.

Mitragyne inermis. Intyú (Dyakossi); Shero (Dagomba).

Smaller than the last, found on ground which is occasionally under water. Its yellowish-white wood is used for beams and rafters. It forms also a beautiful, easily-worked furniture wood.

Mitragyne Africana. Séssëu (Atakpame).

A small tree which flourishes in swampy places and parts overflowed by the streams. Its blossoms are used as hay. The particularly valuable wood is proof against attacks of the termite, very hard, and much used in building. The wood of all the Mitragyne species are valued in Tropical Africa on account of their durability and being proof against weather and easily worked.

Sarcocephalus sambucinus. Akukobasa (Ewe); Kedjetjelo (Tschaudjo); Nyimo (Atakpame).

A small shrubby tree, with long, tendril-like branches, white fragrant flowers, and strawberry-coloured fruit. The wood is used considerably for mosaic work and inlaying.

Similar to the preceding tree in appearance, etc., but the fruit is cylindrical in form, like a small cucumber.

Gardenia medicinalis. Kau belia or abalia (Tschaudjo).

The same characteristics as the last; the fruit is much smaller, round, and furrowed.

Gardenia assimilis.

Gardenia Abeokutā.

These trees are all found in the higher forests as undergrowth, and are very similar in every respect.

Plectronia vanguerioides. Dädäfunde (Atakpame).

Medium-sized tree. Occasionally found as a shrub in the coast and mountain forests. The wood is only useful as firewood.

Pavetta Baconiana. Genferrebiesó (Mangu).

Pavetta crassipes.

Used as firewood.

Morinda citrifolia. Amakḗ (Ewe); Ketyĕlenga (Tschaudjo); Aké (Atakpame); Maticki (Ho).

A tree 32½ feet in height, with a broad, shady crown, seems to be bearing blossoms or fruit all the year round. The flowers are in the form of little round bunches; the fruit is greenish-yellow, spongy, and growing together in large masses—each fruit about the size of a pear. The white wood is not of much value, but the rootwood is sold in the native markets for making yellow dye. Two species of this tree seem to be known in Togo, one found frequently on the coasts, the best known, and another variety in North Togo, less common and with a much smaller fruit.

Compositæ.

Vernonia Senegalensis. Avenya (Ewe); Tusima or Tingma (Tschaudjo).

The only one of the family which attains a height of 19½ feet, and stem of 6 or 7 inches in diameter. The leaves are a greyish-green; the flowers, a yellowish-white, appear in great masses. The wood is fairly heavy, light brown in colour, and very easy to work. Of the many varieties from which the twigs and roots are used for brushes, this one is the most valuable.

CHAPTER VIII

NIGERIA

I. The Rivers, Ports and Forests of Nigeria.

Starting from Lagos, the first port of call, the coast is flat, sandy, and low-lying as compared with the typical seaboard of Europe with its cliffs. Long sandy beaches with scattered coconut palms in the background are more prevalent in this part of Nigeria than the water-covered mangrove swamps, showing rather a stunted growth. Westwards from Lagos there are the scattered mangrove formations in the estuary of the Yewa River, near which is the trading station of Badagri. Following the line of the coast, somewhat better mangrove areas are found towards the mouth of the Benin, Escravos and Forcados Rivers. The estuary of the Niger, extending from the last-named river as far as the Sombreiro, shows varied development of the mangrove type of vegetation, as well as the first admixture of other hardwood trees at the edge of the mangrove zone. On the way one passes the Ramos, the Brass, Nun, St. Bartholomew and St. Barbara, each forming outlets for the forests further north. Beyond the Sombreiro the estuaries of the New Calabar, Cawthorne and Bonny Rivers contain further mangrove areas, usually in the form of large islands. Eastwards of the Bonny River the mangrove to some extent gives way to comparatively large areas known as rain forests, owing to the comparatively heavy rainfall in those localities. The Andoni, Opobo, Kwaiebo form the outlets for these forests.

The Cross, Calabar, Kwa and Akwayefe are the most easterly rivers in Nigeria. In the estuary of each, more especially of the Cross River, the finest mangrove forests are to be seen. Next to these in point of height and straightness of bole are the forests on the banks of the St. Barbara and Forcados Rivers.

The Lagos River, with its present bar-draught of 19 feet, is followed eastwards by the port of Forcados, showing 19 feet. As subsidiaries, and northwards from Forcados, are the inland ports of Warri and Koko, both, and especially the latter, being timber-shipping centres. Sapeli, another 40 miles up the Benin River beyond Koko, was and still remains a timber port of some importance, and from it the trade name of one kind of mahogany, namely Sapeli wood, is derived. Brass, considerably further eastward, is practically a seaside port, to which some produce of the Niger Delta is brought. Degema, Bugama, Bakana, Okrika and Port Harcourt are inland ports all reached from Bonny, situated at the mouth of the river of the same name. Opobo, on the Imo, is yet another inland port with a 14-foot bar at the river mouth. Eket is the small port for the Kwaiebo River, whence small steamers run to Calabar. Oron, on the western side of the estuary, is also a port worthy of mention. Though Calabar is some 15 miles above the junction of the Akwayefe, Kwa and Cross Rivers, it is the chief port of Eastern Nigeria. It is situated on the side of a hill some 200 feet high on the bank of the Calabar River, which is half a mile wide at this point.

Turning now to the next type of forest met with after leaving the mangrove zone, the thick, heavy, evergreen rain forest is seen. On the western side in the province of Abeokuta it has very largely been destroyed, only comparatively small isolated areas remaining. In the Ondo province, however, some of the most extensive and heaviest timber areas of this type are found. A good network of rivers, such as the Ogun, Ona, Oshun, Oni, Shasha and Owenna, when flooded, form the outlets for timber worked in these localities. In the northern part of the Warri province and the southern part of the Benin province large representative areas of the evergreen type are found, though there they tend to mingle with the tall, mixed deciduous forests. To a small extent in the Owerri, but to the largest extent in the Calabar province, the rain forests find their finest development, culminating in the Oban Hills on the eastern side of the latter provinces. The rainfall there is 175 inches per annum.

The Sasswood is one of the first trees to appear when the mangrove swamp gives way to the evergreen forest. Other large trees are the mahoganies, found chiefly on the old banks; red ironwood, with its brilliant red fresh leaves in the late autumn. In fact, these leaves are often taken for flowers, owing to their very bright colour. They gradually, however, assume a dark green colour as the season advances. An unidentified species of gum-copal which grows to colossal dimensions is found scattered rather diffusely and curiously in these areas. Different kinds of ebony, with wood varying from brown to green black, are seen throughout the zone, though, as with other trees, a different species is found in the different provinces; on the whole, the blackest wood is found where the rainfall is heaviest.

The mixed deciduous zone, which consists both of deciduous and evergreen trees, mingles and gradually develops at the northern edge of the evergreen rain forest; in many cases the one goes over into the other almost imperceptibly, and it is only perhaps after half a day’s march that one realizes that one has left the evergreen type behind and reached the forests where half the trees lose their leaves every year. A very large development of these forests is found in the Abeokuta, Oyo, Jebu-ode and Ondo provinces. Very heavy inroads have been made in these forests, and it remains to be seen whether sufficient will be preserved to ensure the future fertility of the soil and the requisite rainfall. One of the most prominent species is the cotton-tree, with its great root buttresses and muscle-like protuberances from the stem. The Obechi, or Arere, is another magnificent timber tree, with soft white wood and maple-like leaves, which grows to huge dimensions. The African greenheart, which may grow 12 feet in diameter, is hard enough to break the blade of an axe. The Iroko, taking the place of oak in African economy, is another tree frequently met with, and it extends its area of distribution as the forests are opened up with clearings. East of the Niger this formation is only found to a small extent in the Onitsha province; a little larger in the northern part of the Owerri province, and still largest in the northern part of the Calabar and the southern part of the Ogoja province. In fact, the finest development of the mixed deciduous forests is found in the last-named province, just north of the Cross River, where it is really at the edge of the true deciduous forest. In this zone some three kinds of mahogany are found, in some places very diffusely scattered, in others up to a thousand mature trees in eight square miles, or in a third nearly every tree a mahogany on both sides of the road for over half a mile. The four species in this zone vary less from province to province than they do in the case of the evergreen forest zone, though the total number may be greater.

Beginning again on the western side, the open deciduous forest or dry-zone formation shows itself over a very wide extent in Oyo, Northern Jebu-ode, and in the Northern Benin provinces. East of the Niger it is of wide extent in the Northern Onitsha and Northern Ogoja provinces, but it also occurs in the northern part of the Owerri province as an artificial product of man’s destruction of the original forest. In some places this formation, owing to the trees being close together, more nearly approaches the deciduous forest. In others, owing to the poor and stunted nature of the arboreal growth, it more nearly approaches the open grass savannah formation. Only north of the Oyo province near Shaki, or north of Ogoja in that province, could it be said that this kind of formation is seen.

One of the most prominent kinds of trees found is the Shea Butter, the nut of which is used in the making of chocolate cream and margarine. This tree, varying in size from a large oak to a short, stunted, gnarled and burnt relic of better forest conditions, is found over very wide areas in the Oyo and northern part of the Abeokuta province. Strangely enough, this tree does not appear in the northern part of the Benin or Onitsha province, and only occurs again in the north-eastern corner of the Ogoja province. The locust-trees, with their open crown and feathery leaves and long pods similar to French beans, are conspicuous all through the zone, and near the villages are specially preserved. Mahogany is represented in this zone as another species which does not attain a greater girth than 10 feet and which is often gnarled and crooked owing to the annual grass fires. A medium sized Cedrela, or hard cigar-box wood, is found in isolated patches in the northern part of the Abeokuta and southern part of the Oyo province. The balsam-copaiba-tree is also very common in this zone in the North Benin, Onitsha and Ogoja provinces.

The forests of this zone are perhaps the least valuable from the financial point of view, chiefly owing to their geographical position and defective means of transport, but economically they are of great value to the agricultural community, both for their forest produce as well as their soil-preserving and rainfall-conserving properties. The chief timber areas are situated in the heavy rain forest and mixed deciduous forest areas, though a few have recently been taken up in the mangrove swamps.

As a minor, though important, development to the main forests are the evergreen hill forests, which find wide development in the northern part of the Jebu-ode, Ondo, Benin, Ogoja and Calabar provinces. On the whole, the species do not vary so much as might be expected, and in many cases it simply means a further distribution of certain evergreen trees beyond their zone of natural development, owing to suitable climatic conditions in these hills. For instance, the red ironwood appears next the mangrove swamp on the bank of the St. Barbara River, again in the evergreen forests near Calabar, and reappears in the hill forests of Oban, much further north. Probably the most typical trees of the hill forests are an unidentified species of gum-copal, as well as several species of Guttiferæ.

The fringing forests are found chiefly on the banks of the rivers in an area which is otherwise covered with the open deciduous or dry-zone formation. Two leguminous trees are most typical of this zone. Stray deciduous or evergreen trees from the other zones are also seen. Such forest is thick with a fair amount of undergrowth, and the trees form a close canopy. The fringes vary from a few yards to half a mile in width.

A further subsidiary form is found on the summits of the highest mountains, such as the Boji Hills, with their stunted satinwood trees, shrubs and grass. In some places there is yet another minor formation, that of the freshwater swamps. Some typical examples of these are found on the banks of the Calabar, Osse and Owenna Rivers. In most cases only one, or any how only a few species of trees are found, whereas in the major formations several hundred different species appear. The growth in these swamp formations, both mangrove and freshwater, is on the whole not so large as that of the evergreen forest. Again, the evergreen forest does not show such fine development or such height of tree as the mixed deciduous forests, though occasionally the greatest girth of bole is found in the evergreen forests.

II. The Mahogany and Timber Industries.

According to Nigerian law, timber includes planks sawn for logs and trees hollowed out or shaped for any purpose whatever. The timber-working industry, then, is a wide one, covering really three distinct fields of activity, though one or more may be combined. First, there is the felling of mahogany chiefly, and other furniture-wood trees for export. In the second place, the native, and to a slight extent the European firms, cut timber for local use, mainly in the forest, such as planks, canoes and posts. Thirdly, there is the Government, which under the auspices of the Forestry Department chiefly, and to some extent under the Public Works Department, cuts timber of various kinds, chiefly Iroko, for railway buildings and road bridges.

Turning now first of all to the export industry, which is most important at the present time, though the local demand for timber will soon dwarf that of the former, there is a definite sequence of action necessary in embarking on this form of economic development.

As soon as a firm decides on timber-getting, an application (made out in triplicate) has to be sent in with good maps or plans of the area, which is applied for, to the Conservator of Forests of that circle. It is understood that the area in question has been thoroughly examined by the firm before the application is made. A fee of £3 in stamps as well as a banker’s guarantee of £400 for each area of 100 square miles is also necessary before the application can be considered. The species of tree to be cut should also be stated, as well as the names of the villages and chiefs occupying or living in or adjacent to the area. Owing to the time taken in making the fullest inquiries into the occupancy and other rights, as well as ascertaining the financial standing of the firm in question, it is usually several months before the applicant hears that the area has been granted.

Before this the applicant should also forward a confidential statement, stating exactly what capital there is available to develop the timber areas. An additional banker’s reference to the Crown Agents will save unnecessary delay in the granting of the area.

Before the notification of the grant of the area, the licence is made out in the Conservator’s office, for which a £5 stamp as well as three good maps are necessary. Roughly, an additional £2 10s. is required to satisfy the legal fees upon registration, which follows immediately after the execution of the licence by the licensee of the grantees. It should be especially noted that anyone acting on behalf of a firm should be in the possession of a registered power of attorney, enabling him to act in the fullest possible way for the applicant or company acquiring land rights. This power of attorney should be registered beforehand, otherwise another delay will ensue whilst this is being done.

As soon as the area is granted, the applicant should mark all boundaries with the necessary marks, which also appear in the licence. Within six months after the granting of the area, work has to be begun. The first proceeding is to send in a list of trees, numbered serially from one upwards, stating the species, size (girth at 10 feet above ground), where situated, name of nearest village and chief occupying land in the vicinity, together with the amount of fees and royalties payable on the trees. The trees have been marked and numbered previous to the duplicate lists being sent in. It is usual to pay a cheque or bill for the fees and cash for the royalties, then one of the two lists sent in is returned to the sender marked “Permission granted.” Felling can now begin. On the whole, the general practice is to cut the trees down in the earlier months of the year and have nearly all completed by March or April. Logging, with a cross-cut saw or axe, and squaring with an axe and adze, follows as soon as the trees are felled, and, as it takes longer, continues afterwards right into May or June. Hauling begins as soon as sufficient logs are ready to be drawn and the hauling roads have been cleared. Usually different gangs haul to those employed on the tree-felling and squaring. Eighty or a hundred boys are lined up and haul on two ropes attached to the end of the log. The log, having been shaped at the end to allow easy hauling over the rollers or ground, is “snaked” along to the nearest waterside, river bank or creek. Here two timber-dogs are driven in the end for attaching the cane or rope to hold several together. In the smaller streams or creeks, single logs, or two joined together, float down to another station, where a bigger raft of 40 to 100 logs is made up. In a good many rivers the rise of the water takes place in July, and it is then that the largest number of logs float out. Another lesser rise for the most part, except in the largest, such as the Cross or Niger Rivers, occurs in October, when all logs possible are got out for that season.

Logs left by this last flood usually have to stay until the following year, when the river will rise again. Sometimes as many as three seasons elapse before it is possible to get out some logs. The higher reaches of the Owenna have an unenviable reputation in this respect. Several short rainy seasons following each other successively cause the same result. The Ijors are the chief “waterboys,” who contract to take logs down the creeks at 5s., 10s. or 15s. a log, according to distance and nature of the creek. The Ossiomo has also a bad name, owing to its swift current and the liability of losing the logs.

Most labour is engaged direct, though handed over to a contractor who is paid 1½d. to 1¾d. per foot of timber squared or logged brought to the nearest waterside. The labour, however, is paid by the European firm, which is entirely responsible for the payment.

The shipment of the logs is made at Koko, Warri or Forcados from Lagos and at Lagos itself, the first-named port taking the majority. Many firms have a branch store and office at this port, or another firm ships logs for others not represented at a fixed charge per log. Export entries showing numbers of logs, size and value are presented to the Customs Department before shipment. Koko, which used to be quite free from the Teredo borer, is now unsafe for logs after a fortnight’s floating in the water there.

The shipping companies do not particularly desire logs as freight, owing to their weight and unwieldiness in handling. Space is left between them to some extent in the hold. The hatches have to be especially long to take the biggest logs. From Lagos, Forcados, Calabar, etc., a freight rate varying from 35s., 40s., to 45s.[2] per ton for 2¾, 3 and over 5-ton logs. Koko, on the other hand, is only 25s., with 10s. extra for primage. This is the same with the other freight rates.

During the voyage the logs gradually dry, and often by the time they are put into the timber yard of the brokers they are split or cracked. Only the best logs, 30 feet long and quite sound at the start, stand all the rough handling they get. Auction sales take place about once a fortnight in the busy season, though sales by private treaty take place occasionally. Logs can sometimes be sold ex quay too, though by far the most of the wood is sold by public auction. The inclusive charge of landing, stacking and selling at the dock is roughly 10 per cent. of the value of the log. In fact, it is quite a considerable item of expense, and often makes the difference between profit and loss on the smaller and lower-grade logs. All logs are sold by the superficial foot, i.e. one foot square, one inch thick “sale measure.” Sale measure obtains only in the mahogany trade for square logs, and is roughly 20 per cent. less than the actual cubical contents of the log. Round logs are measured and sold by extreme (full) measure. A wane of six inches or less is left on the squared logs, because it makes them less liable to crack and split at the corners, and also it saves a good deal of timber which would otherwise be wasted.

Liverpool is the best mahogany market, though fair prices are obtainable for good logs in London. Hamburg used to be the market for Gaboon wood, and on the whole new woods were better received than in the English market. As a rule, figured mahogany always commands a good price, whereas plain wood, with the exception of roey or counter-top timber, only fetches a moderate or low price, unless the market is understocked at the time. The best wood is obtained from the Ivory Coast, and the next best is Benin or Lagos wood. Sapeli wood is very heavy, and found a market chiefly in Germany. Cross River wood has yet to be shipped and proved, though samples there looked very good and even showed some figure. So far, only the leased areas have been spoken of. Now we return to the Reserves, where, however, permits to cut trees can only be obtained. Here leases are usually not granted. The rules with regard to replanting do not apply in the same way, as all planting is in the hands of the Department. On the whole, stricter supervision may be exercised in the Reserves than on leased areas. Although a firm has no lease, the security of tenure for cutting the trees would be at least as good as under a lease. No other firm would be in the same position to fell and extract timber as the first one to whom permission was granted. The Government would not allow any other amounts of trees to be felled that would injure the working of the forest by the first applicant.

Local felling is conducted by one or two firms in their areas, which were in the first instance obtained for export timber. For the most part, however, the natives or native foreigners fell various kinds of trees such as Iroko, Chlorophora excelsa, Owussu, Sarcocephalus esculentus, Ume, Pterocarpus soyauxii and Pterocarpus Osun, Edat, Saccoglottis Gabunensis. Nearly half the permits issued are for Iroko, the main building timber of the Yoruba and Benin and Ibo countries. The Camwoods or Barwoods are felled next to obtain the brilliant red heartwood, chiefly from the roots, but also from the stem. A dyewood which produces a fast colour is obtained by rubbing a small pointed section on a flattish piece of the same wood. A yellow dyewood is obtained from Anyeran Afrormosia laxiflora.

The canoe-making industry absorbs a large number of trees. The native, chiefly Ijor, chooses the tree with great care as to straightness of stem and length of bole. It is felled near a river bank or otherwise reasonably accessible place. First of all two sides are flattened parallel to each other; at the same time the length of the canoe is chosen and the tree bole cut off at the required length. A narrow groove about half the depth of the diameter of the log is now made with small axes and an adzelike instrument. The log is then shaped externally like a canoe, especially both bow and stern. Next, more wood is cut away on the inside and some pieces of wood stuck across to keep the canoe open. A shelter is put over it during a hot day. As soon as the requisite amount has been cut out, dry palm branches are placed all round the canoe outside on the ground; longer cross pieces are fixed over the canoe of the required length for thwarts when the canoe is finished. Long stakes are driven into the ground opposite each of these on each side of the canoe, so that the natives can obtain a strong leverage over the canoe. Fire is now put to the palms, beginning with the bow of the canoe. The heat makes the wood expand and thus opens the canoe; at the same time the natives pull down the stakes at the side of the canoe and press the cross pieces into their places. This extends gradually the whole length of the canoe in the course of the day, which is the most strenuous of all, as upon the energy and care exercised on this day in making the canoe open out evenly in its entire length and the same amount each side depends its future success in the water. It may turn out lopsided, or, as is often the case, a hole may appear in the middle of the stern end, owing to the centre of the tree having been rather old and rotten. This can be covered over, and is often above the waterline.

Canoes vary in size from the Oguta canoe, in which the paddler has to keep one foot in the water to balance the canoe, to the twelve-puncheon canoe of the big traders. This last will have a great hollow dug out fully 6 feet deep at the stern end and over 60 feet long.

The sawyers cut the tree all round, fell it, and then cut it into 12-feet length logs, as far as the bole allows. The huge branches are left untouched. A large pit is dug quite close to the logs, and one by one they are placed over and sawn, first two sides and then into three large planks; finally these are cut into 12-inch planks one inch thick. Most of the work is done within four miles of the railway line or within twenty miles of a large town, such as Jebu-ode, Ife, Ibadan, Abeokuta. Truck loads of this timber may be seen at Ilugun or Ogunshileh, on the Nigerian Railway.

Permits are also issued for the making of smaller articles, such as verandah posts, culled out of a guttiferous tree; sleepers, sawn from Iroko (Chlorophora excelsa); sword-sheaths, made from Ogohen (Musanga Smithii); mortars, cut from Apa (Afzelia Africana); pestles, fashioned out of Eba (Lophira procera).

The dyewood industry in itself is chiefly developed on the banks of the Cross River. The trees are felled in the Oban forests, allowed to lie a year or two, then cut up into long 3- to 4-inch irregular-shaped scantling or poles. These are sold chiefly in the Oban market, after which they are cut into small sections. Women take these up and make lozenge-shaped bricks about a foot long in the greatest length. These are sold at 6d. each.

Under Government auspices, one of the first enterprises was the sawmill at Etehetem. A very hard redwood, termed Apassa by the Efiks (Mimusops lacera), and also mahogany (Ochrocarpus Africanus) were cut. Owing to the difficulty of expansion and the increasing cost of the logs, the plant is to be moved elsewhere. The railway had a small plant at Han, where timber and sleepers were cut for the Baro Kano line. At Ebuttemetta the railway also have a small mill for cutting chiefly Iroko, Apa, and a little redwood.

Of the various firms, Messrs. McIver had a small mill in Lagos, chiefly for sawing up mahogany logs not worth shipping to England. Later, in 1909, Messrs. Miller Brothers built a mill at Koko town; Agba (Copaifera sp.?) as well as mahogany logs have been cut; Ebbe and Obiache, and Obechi (Triplochiton Nigericum), the last-named being a good whitewood.

The Anglo-French Company have started a plant near Oron Eastern Circle to cut sleepers out of mangrove wood, Lagenaria and Rhizophora.

Lastly, the Government have started a new mill at Apapa, near Lagos, for cutting logs obtained near Akilla, on the Oni River, in the Abeokuta province, and the planing, grooving and recutting is done in connection with the Public Works yards and furniture-making establishment in Lagos.

The Akilla work is run entirely by the Forestry Department. Trees are felled, cut into logs and brought to the waterside; then, rafted with others, floated in kerosine tins on lighter wood to Apapa. A regular rate is charged per cubic foot. Work was started in August 1914, and already several thousand logs have been delivered at Apapa.

III. The Permanent Forests or Forest Reserves.

In the main, all Forest Reserves become the permanent forests of a country. So far as Nigeria, for instance, is concerned, certain definite and well-defined portions of the original forests have been set aside, by agreement with the natives, as Forest Reserves. If these areas had not been set aside, they would have been liable to destruction under the form of shifting cultivation which the local people practise. For instance, at Olokemeji there are several thousand acres in the middle of the Reserve which were cleared some years ago and have not yet grown up. This would have been the fate of the rest of the forest if it had not definitely been placed under the care and protection of the Forest Department. The same applies to other areas scattered over the country.

It is somewhat hard to define the meaning of a Reserve. Essentially it is an area permanently set aside for the production of timber or other forest produce. In many cases, however, the trees or the forests have to be preserved in the interests of the climatic conditions of the locality. If it is found that by cutting down a forest the rainfall decreases every year, the springs dry up, and the land becomes covered with grass, where actual grass fires kill all young vegetation and even hinder farming operations, then the forest must be reserved. To take some examples: In the colony of Sierra Leone there is a Peninsular Mountain Forest, a large and valuable Reserve, 80 per cent. of which is covered with red ironwood, Lophira procera. Then in the Protectorate there are the Kambui Hills, Kennema, then Nimmini, and the Loma Mountain Reserve. In the colony and Protectorate of the Gold Coast there is the Dunkwah Reserve. Some of the most improved reserves in the southern province of Nigeria are in the Western Circle. There are Olokemeji, Mamu, Ilaro, Oshun, Owenna and Ondo Reserves. Again, in the Central Circle there are the Okumu, Obagie, Gilli-gilli, the Uhi, and the Ogba Forests.

In the Eastern Circle there are the Oban, Ikrigon and Ajasso Reserves, in all aggregating about 2,000 square miles.

Contrary to the usual idea, we have seen that a Forest Reserve is in reality only a permanent forest, which is primarily maintained for the definite production of some forest or other product. It cannot be too much emphasized that it is definitely set aside to be used wisely; and for all the trees taken, suitable replanting operations are undertaken by the Forest Department. The name “Reserve” is in fact rather a misnomer. In the early stages of a forest administration it is convenient to talk about Forest Reserves as distinct from the rest of the country, which is usually covered with forest and termed “unreserved” forest. It may, later on, become agricultural land; it may also be reserved, in which case it becomes a Forest Reserve or one of the permanent forests of the country. The main point to be observed with a Reserve is that it is primarily for use, and not that the timber is to be reserved and not to be utilized by the general public. Even in those cases where the local demands of the people are great and have to be satisfied first, before any outside timber exporter is allowed to work the forest, it is utilized to the greatest extent compatible with its maintaining a yearly permanent output of timber or other forest product. Permanency of output is the watchword, and strict utilization of the increment-bearing capacity of the forest each year. The increment is of course the amount which each tree grows each year. This amount, added together over the whole area, makes up the quantity which may be felled, on the proportional area during the rotation, in any one year. Thus, to give a concrete example: If an area is 100 square miles in extent, and the rotation is 100 years, then one-hundredth of that area, or one square mile, may be cut over in one year; also, if the sum of the growth amounts to 40 cubic feet per acre per year, this means to say that an annual cut of 25,600 cubic feet can be made each year over one square mile of the area, in the case of a clear felling of all the trees, or spread over an area of 10 square miles in the form of a slight thinning of the trees. In the Temperate Zone, on moderate soil, 40 cubic feet of timber per annum is a good yield, so that in the Tropics we may expect a yield of quite double this amount; therefore it will be seen how readily the forest can grow and how much timber can be obtained permanently from the Permanent Forests or Reserves.

Another great advantage of the Permanent Forest or Forest Reserve, compared with the ordinary leased areas, is the fact that the planting is done by the Forest Department and not by the leaseholder. In an ordinary leased area this planting is a considerable source of expenditure and worry to the leaseholder, and even then satisfactory results are hard to be obtained. He is continually being reminded of his planting duties by the Forest Department, and he is continually striving to keep up the proportionate amount of planting, i.e. 24 trees for every tree felled, and this is by no means easy to attain. Although the annual leaseholder working in a Forest Reserve may be under greater supervision and more stringent forest regulations than in the ordinary leased areas, on the whole his prospects of getting out greater quantities of timber more expeditiously and cheaply are much greater than in the ordinary areas.

Particularizing some of the great concrete objects for which reserve is made:

Firstly, the permanent supplies of timber of all kinds, with a view to turning out approximately the same quantity year after year in perpetuity—in fact, if anything, gradually increasing the output year after year. This means to say that, although the forest is cut down, it is replaced at the same rate at which it is cut down. Putting it in another way, there must be as many blocks, or portions or actual “stands” in the forest as represent the number of years which elapse between the time a tree is planted and the time it is cut down. This period is known to foresters as “the rotation,” and in northern temperate countries, for Coniferous trees the time is usually reckoned at about 80 years. In the tropics, with mahogany, Iroko and other timbers, it may be only necessary to allow 60 years, or perhaps on very poor ground 100 years. In the case of teak in Burma, a rotation between 80 and 100 years is perhaps about sufficient to enable merchantable timber to be produced. Putting it in another way, in the forest, in order to have the permanent yield, there must be sufficient trees of each girth class, so that when the largest, say those over 12 feet in girth, are cut down, there must be sufficient of those between 10 and 12 feet, which will grow during a 10-year period (in which they are cut) from 10 feet to 12 feet in girth. At the present time it has been found convenient to classify each class as “under 2 feet, 2 to 4 feet, 4 to 6 feet, 6 to 8 feet, 8 to 10 feet, 10 to 12 feet, and over 12 feet.” The object of this is to clear away, or have cut, all those trees over 12 feet in girth. This makes room for younger, quicker-growing timber. Although, under the Nigerian Forest Law, the girth of mahogany has been reduced to 11 feet, and in some districts to 10 feet, eventually, as the older and more unremunerative slower-growing trees are cut down, it will be possible to reduce the girth still further. To put this question of the permanent yield in yet another way: All the trees from one year old, or from the smallest size to those over 12 feet in girth, represent what we may call the forest capital. Now, the object of the rotation is only to take the interest on this capital; that is to say, the amount which grows on all the trees over the whole area for one year. It would, however, not do to clip off little pieces from each tree over the whole area, as they would be quite useless as timber. Therefore this amount is calculated out as so many cubic feet per annum, or so many trees above a girth of 12 feet or 11 feet, or whatever the girth limit may be, and this amount, either in cubic feet or in the number of trees, is allowed to be cut down each year. Then we know that year after year this amount can be cut down again, and as the soil and other conditions improve and the rate of reproduction is hastened by proper cultural methods in improving the soil, by draining and other methods of amelioration, still larger results may be obtained.

Secondly, the object of these Reserves is to produce firewood, more especially in the neighbourhood of large towns; in fact, already in several cases, firewood plantations or Reserves have been made, such as those at Ibadan and on the sandy flats near Lagos. In these cases, trees five, seven or ten years old are large enough for that purpose, more especially of the following species, Cassia Siamia, or Albizzia Brownii.

Thirdly, to provide grazing land, more especially in the more northern part of Nigeria, where the object is to divide up the area, so that so many cattle may graze on each area in different years, or for different periods of the year, so as to give the pasture and small trees which may be growing a chance to revive and grow again. By this means the pasture is improved and made of permanent value. It is also possible under this system to undertake permanent improvements in these large pastures by a certain amount of drainage in the lower parts, and fire protection in the upper and higher parts. In this way the cattle obtain a better pasturage and reach maturity all the quicker. In times of bad season, too, some of the closed areas may be opened for pasturage, thus ensuring that the head of cattle may not be allowed to go down owing to death due to drought or lack of pasture. In this way the grazing reserve acts as a kind of insurance against loss of stock in bad seasons of no rainfall.

Fourthly, the production of oil seeds and nuts, such as the Oil Bean, Pentaclethra macrophylla, or the African Wood Oil-nut, Ricinodendron Africanus. It may also be the production of Cola nuts, which thrive in the forests in the shade, or in the partial shade, of other forest trees, and the Cacao Bean, which also, in certain localities, should stand in the partial shade of forest trees, more especially in the dry season.

Fifthly, the production of fibres, such as that from the tree known as Eso, Firmiana Barteri, the bark of which is used for making rope. Then there are the various creepers, such as Kakoba, Entada scandens, which is also used for making rope by the Hausa and Yoruba, more especially fly-switches by the Benin natives. Then there are the canes, such as Egbe, used for roofing amongst the Yorubas and Okakan, Eremospatha sp. (large Benin rattan), and Ikan, Eremospatha macrocarpa (small Benin rattan), also used for making rope, and a kind of string which both the Benin and Jekii natives use for tying lath pieces together in house-building and in making coverings for their canoes.

Sixthly, the production of domestic articles, such as sponges, Luffa Soudanica, or wrapping-leaves for food, termed Ewayon by the Yorubas, or thatching laths, Ebe by the Benin natives, and the roofing canes termed Itebe by the Yorubas.

Seventhly, the production of medicinal plants, such as those for native Ju-ju; and some, such as Cassia occidentalis, Cassia fistula, also useful to Europeans.

The main difference between the beautiful, untouched existing forests and a Forest Reserve is chiefly in the matter of management. In the unreserved forests a lease may be granted for five or seven years, and the leaseholder may fell a great number of trees, such as mahogany, Iroko, etc. At the same time there is nothing to hinder the natives or original occupier or user of the land from clearing the greater part of the forest, except the protected trees, and making farms throughout the area; thus, in fact, gradually hindering, or at least reducing, the possible output of timber from that area. No new seedlings come up in these areas which are farmed, and, in fact, the fires which are made in the course of clearing the land for farming operations kill the young growth of all kinds. In reality, in a Forest Reserve there is more permanency with regard to the output of timber than in the original forest; there is, in fact, absolute permanency. Although no actual lease may be granted for a period of several years in a Forest Reserve, yet, as a matter of fact and usual experience, after a year’s working it would be quite unlikely for a Forest Department to stop the timber merchant from working the forest again, or rather from allowing him much the same number of trees as he had in the former year, because not only would the revenue from the forest suffer, but timber experience would have to be gained with another firm, which means a loss of time as well as revenue. Thus, in the ordinary way it is more satisfactory to have the same firm working in that locality year after year, provided they pay an adequate price for all the timber trees which they have. They can then invest the proper amount of capital in plant and hauling appliances, and thus make a greater profit and exploit the forest to better advantage than if a fresh firm came in year after year.

To give a more concrete idea of what these areas mean, we will take it that on the average there are only 50 trees per acre which are of some value or another, either for timber for local use or for export, and taking the average rate of fee at only 4s. per tree (it should be noted that mahogany and so on are rated at £2 16s. per tree), it will be seen that the value of these forests is in all £12,800,000. This sounds a great deal, but when it is considered what a very large number of trees can now be utilized, either locally, in the form of planks and scantlings, and joists for posts, not to speak of all the various kinds of mahogany, Iroko, walnut, ebony and other substitutes which can be used for export, it will be seen that this value is none too great; in fact, to the timber leaseholder they would be worth at least ten times as much. Of course, in this calculation all sizes of trees above a girth of 4 feet are considered, for the sake of making the valuation as complete as possible. Naturally, the smaller girth trees would not immediately be utilized, but when we are totalling up the amount of forest or wood capital involved in the valuation, it is necessary to include them and put a value on them. If the necessity arose, even they could also be utilized and would at least bring in the amount of the lowest valuation per tree.

The Forest Reserves stand also in a special position to the local people, for, after all, these Reserves formed originally part of the forest from which were supplied all the major wants of the native, such as timber, firewood, oil nuts and seeds, fibres, domestic articles and medicinal plants; therefore, whatever the main lines of protection of a good forest, the needs of the people of that locality must have the first consideration. After these wants have been fully supplied, then any surplus in the way of timber or other commercial products can be sold or exported elsewhere. This leads us to consider the fact that a Permanent Forest or Forest Reserve leads to a permanent source of revenue from that particular forest. Owing to the fact that there is the permanent yield of timber established in that area, it means that permanent money is being obtained from those trees and being brought into the Treasury as part of the permanent revenue of the country. If there is any increase, owing to the increased value of the timber trees thus gained—and the more stability there is, the better for the country—better arrangements can be made with regard to the reproduction of the forests. If there is a greater revenue being obtained from the forests, even more money can be justly expended by the Forest Department for the buying of better implements for planting and the Forest Station generally, for the making of permanent improvements in the forests, such as draining, road-making and fire protection. If these forests are not protected and unreserved, then in the course of time they must completely disappear, owing to the fact that man is so constituted that if he sees land, which may or may not be suitable for agriculture, covered with trees, he naturally thinks it would be better to cut these down and see what agricultural crop will grow there, regardless of the fact that there may already exist, or he may have cleared, fifteen times as much land as he requires for farming operations each year.

In addition to all the above, there are the indirect effects of forests, which have been considered in the section dealing with the relation between Agriculture and Forestry. On the whole, it is better for the Central Government or Federal Government to manage the Forest Reserves, as by that means there is greater impartiality in their management and more stability and continuity in the Forest policy adopted towards them. In each case, however, it is essential to have either co-opted or elected representatives of the locality, either by the chiefs or by representatives of the people, so that the wishes and needs of the locality may be thoroughly considered.

Lastly, and by no means the least important feature of the Forest Reserve, is the æsthetic view. In the regions of Permanent Forests, healthier localities are afforded for the people, and they are also prettier and more pleasant. This applies not only to temperate-zone forests, but also to tropical forests. It is a well-known fact also that where there are permanent forests the value of the other land in that locality is always rated higher, and is worth more for leasing if adequately covered with a sufficient proportion of forest.

IV. Afforestation in Nigeria.

The Forest Department, not being content with obtaining a revenue out of the forests from the trees cut down for export or for local use, have spent and are spending several thousands of pounds each year in planting valuable forest trees. Going back historically before the time when the Forest Department had a sub-head in the estimates for “Labour for Plantations” or “Teak Plantations” or “Upkeep and Improvement of Forest Reserves,” we had the annual planting of many tens of thousands of mahogany-trees by the timber leaseholder. The whole of this was chiefly done in the Benin district of the Benin province. Although this transplanting of self-sown mahogany-trees into better situations near timber camps, or at the side of falling roads and into the spaces left by the fallen mahogany-trees, was by no means carried out very systematically or under very expert planters, the results are all the more creditable to those who so early started to reproduce the forests. It is most interesting to see in different parts on the banks of the Osse River young thrifty plantations now nearly twenty years old and nearly 30 feet high. In a similar way in the forest there are to be seen large numbers of somewhat smaller sized mahoganies growing singly or in groups, only needing a certain amount of clearing and tending to prevent their being overgrown by other forest trees. Scattered though they are throughout the forest, it is not too much to say that the prospective younger aged forest will be more valuable than that which originally stood in its place.

Easier to find, though in some way less attractive to look at, are the regularly made mahogany plantations of the Forest Department. In addition to isolated specimen trees which are found in the forest Arboretums at Calabar, Degema, Benin City and Olokemeji, several thriving plantations are found near Benin City in the Ogba and Obagie Reserves, in the Ilaro, Mamu and Olokemeji Reserves. In the last-named are the most extensive areas of all, and also, despite many failures owing to experiments on bad soil and seasons of extreme drought, the growth of the trees gives the greatest promise of mature trees, or at any rate merchantable trees, being grown in a comparatively short period. Plantations have also been made at Awka, Udi, Okwoga and Ida.

Already on the old town site of Ijaiye, mahoganies have been seen over 6 feet in girth which have grown up from self-sown seedlings within a period of about sixty years. The soil in this locality is none too good, and the rainfall on the average certainly does not exceed 50 inches per annum. Near 47 Benin villages small communal plantations of mahogany have been made.

All the mahoganies apparently, especially when grown in “pure” plantations, are attacked by a leading-shoot borer, which so weakens the leading shoot as to make it fall off, and the tree subsequently grows with two leaders. Later on this forms a large fork in the tree, which, when the time comes for felling, is by no means to be despised, forming as it does usually a very good “curl.” In other respects it is disadvantageous in reducing the length of the single straight bole. In this manner it has the effect of reducing the number of logs of long length and even shape and large size that can be obtained in one tree. In many cases, a log can be cut above from each limb forming the fork; but of course these are both much smaller than those from the bole, and are usually not nearly so straight, and one or other of the limbs is liable to be broken when the tree is felled. In the original forest only isolated trees are attacked by this leading-shoot borer, whereas in a plantation nearly all the trees suffer by its depredations.

Various species are being tried for admixture with the mahogany in order to hinder the spread of the attacks. At Olokemeji there is a mahogany plantation largely interplanted with two species of Mimusops multinervis and Mimusops Elengi. So far this appears most suitable, as the soil is kept thoroughly covered by the dense shade cast by the Mimusops, and there is a very considerable space between each mahogany-tree. However, the mahogany grows faster than the Mimusops, so that after the first few years it does not have so much effect. Even so, it tends to keep the bole of the mahogany clean and the state of the soil in mechanical and physical condition such as to be most conducive to the growth of mahogany.

A mixture occasionally seen in nature has yet to be copied—that of mahogany and Chewstick (Anogeissus leiocarpus). To some extent it is seen at Olokemeji, where the self-sown seedlings have come up in a mahogany plantation, but of course they were rather too late to effect the result, i.e. protecting the mahogany from the leading-shoot borer. At Ilaro a most typical Mahogany Reserve, an isolated plantation made amongst secondary growth, has more than held its own with little or no tending after the first two years, and yet the trees overtop all the surrounding growth. In some cases, both at Olokemeji and Mamu, either self-sown or planted Iroko (Chlorophora excelsa) is found growing amongst the mahogany. Owing to the attacks of the coccus on the Iroko hindering its height growth, it has not had as beneficial an effect as might have been expected. Transplanting self-sown trees from an overshaded locality in the forest, where they usually first appear in a more open locality, has proved on the whole most successful. Again, transplanting self-sown seedlings scarcely one year old from an overshaded locality into one with more light has accelerated the growth of the seedlings, preventing them being killed by the excessive shade, and at much less cost has thus established a small plantation in the Benin forests.

With the collection and planting of the seeds from the teak-trees originally planted about 1889 in the Ebuttemetta garden, a new area opened in the afforestation of Nigeria. Seedlings developed rapidly, and were found to grow at least 10 if not 18 feet in the first year. Although not always keeping up this promise of exceedingly rapid growth, more especially in height, the teak bids fair to become, as in Burma so in Nigeria, the most valuable of all trees. On the whole it has been by far the most extensively planted tree of any in Nigeria, excepting that in the case of mahogany many more have been planted in the Central Circle. Teak plantations are now found as widely apart as on the banks of the Cross River near Ikom, Inkum, Ndeh and Ikrigon amongst the historic stones, and in the Arboretum at Calabar. Near Ndeh, for over a quarter of a mile the river bank is quite enlivened by the large and showy leaves as well as the tall, thin stem of the teak. To a lesser extent, though appearing more picturesque, is the riverside plantation on the opposite bank just below Abragba. In a district with a rainfall of about 60 inches and a deep sand alluvial soil, the teak so far has proved quite at home in the Cross River districts of the Eastern Circle. Even amongst the thickly growing grass at Ikrigon they have survived after coming up from seeds sown at stake, and bid fair to become an established tree of that locality.

Teak has also found a place in the plantation near Mpot and the Oban Reserve. Going over now to the Central Circle, we have Oria, situated near the right bank of the Niger in the Benin province, with its rapidly growing teak plantations. Again choosing a local climate similar to that where teak is found has so far proved it to be a most suitable tree for this locality. Many other trees do not thrive or attain much size near here, so that the teak is all the more valuable for that reason. Near Benin itself, with its heavier rainfall and comparatively approximate to the sea (about 45 miles), it is doubtful if teak will do so well. Even so, growing more slowly, it would prove an additional most valuable tree to those already found growing in the district from which timber has already been obtained.

Again, in the Western Circle the very largest teak plantations are found: even from the railway carriage window you get an impression of the extent of these just before reaching the Eruwa Road station, and again just after leaving Olokemeji station, between 85 and 90 miles from Lagos respectively. Despite one or two fires, trees at Eruwa Road show quite average growth for the Southern Provinces of Nigeria. In seven years the trees had reached a girth of over 12 inches and a height of over 25 feet. Happily, they were not fruiting so profusely as at Olokemeji. This plantation is all the more interesting in that it was made primarily for the use of the Railway Administration to supply teak timber for sleepers and constructional work.

On closer inspection it will be seen that the Olokemeji plantations nearest the railway comprise six “falls,” “stands,” or “compartments” of 25 acres each, adjoining each other. Although the trees everywhere have not grown as well as on the better soil, these are far and away the largest plantations of any in Nigeria. Each “stand” is separated from the next by a broad ride and top and bottom by a broad road. Near by these are another two compartments of 25 acres each, though neither of these is entirely filled with teak, as also the first one in the other series. Nearer the bungalows there are the first made plantations of 1908, thriving, yet growing on the poor laterite soil. These stretch away nearly half a mile into the open deciduous forests at the back. What a strange contrast is presented in the dense, close growth of the teak plantation, with its soil covering of decaying and large brown leaves of the teak, compared to the stunted growth of Red Ironwood, small Bauhinia, some Paradaniellas and a few gnarled oak-like Shea Butter Trees! Such teak plantations open up a long vista of future developments in the conversion of the poor dry-zone vegetation into forests of valuable trees, both with and without extensive permanent improvements of the soil and subsoil. Even the large raceme-like clusters of the flowers, almost covering the whole of the teak trees in April and May, are not to be despised for improving the looks of a grassy lawn near a bungalow. A glimpse through the tall Terminalias on both sides of the Ogun, just before the curve is reached at Olokemeji village, reveals yet another teak plantation on the lower slopes of the easternmost of the two hills. Olokemeji means the “man of, or owner of, two hills” (oke means a hill, and meji means two, in Yoruba). Again, still further along in the valley of the stream, near the station, are some other older teak plantations from the years 1910, 1911. Here there is yet a different contrast. The broad, wide masses of the teak plantation are still on one side rather overshadowed towards the hillside by the giants of the mixed deciduous forests, such as the cotton-tree (Eriodendron Orientale) and Sterculia cordifolia and ebony (Diospyros mespiliformis). However, later on the teak, growing on better soil than is found in many parts of the Olokemeji Reserve, will no doubt equal it, if not surpass it.

Further to the south, in the Ilaro Reserve, teak has not proved to be so much at home; although growing well the first year or so, the rate of growth since then has been distinctly disappointing. The soil may have been too damp, and the rainfall of the locality may be a little high, and perhaps later on it may be proved that it can be grown on the higher land at a profit.

Further eastward and further northward, in the Mamu Reserve, the teak has grown as well, if not better than up the Cross River. Trees five years old have reached a girth of 24 inches and a height of 35 feet; with its good soil and comparatively high rainfall, probably rather more than 60 inches, Mamu bids fair to be one of the homes of teak in Africa. The older plantations on the river bank, some three miles away from those on the side of the Ibadan-Jebu-ode Road, have done nearly as well as those standing on inferior soil. So far the only damage done to any of the trees anywhere is that caused by a mistletoe-like parasite termed Afoma by the Yorubas, and known botanically as Polystachys odorata. However, only isolated trees having been attacked both at Olokemeji and Mamu, it is not difficult to combat its presence by cutting the trees down and burning the parasite. Still further north, on the bank of the Ogun just above the bridge on the Oyo-Iseyin Road, is yet another teak plantation. This was mainly formed by many of the seedlings in the nursery not being transplanted in time and being allowed to grow up altogether unthinned. Teak, however, forms such very persistent side branches, and has such a tendency to flower and fruit early in its existence, that only helps it to form a clean straight bole and retards the period of flowering by being planted close together. Also, nearly 5 per cent. of all the stems have a tendency to bend over and form stronger side branches than a leader, and have, in fact, rather a more shrub-like habit than that of a tree. Again, quite 1 per cent. grow very slowly right from the beginning and thus sooner or later get suppressed. For these reasons, then, more are required right from the beginning in order to form a full crop of clean-boled timber.

In the Ondo Circle there are some teak at Awshun, where, owing to rather a high rainfall and somewhat low-lying ground, the trees have not grown so very fast after the first year.

In addition to isolated specimens over twelve years old in the Olokemeji Arboretum region, the oldest trees of all are found in the Ebuttemetta gardens near Lagos. These trees are nearly thirty years of age, and show a girth of about 6 feet. By no means growing on good soil, or in a suitable locality either with regard to elevation or the close proximity to the lagoon and the sea, useful for the best growth of teak, they do not at all show the possible limits of growth of this tree. Already sample sections have been cut from one or two of these trees and reported on most favourably by the Railway Administration. Similar samples have been sent to the Imperial Institute for exhibition purposes. In a short time the first thinnings of the plantations will take place, and it will be possible to see for what purpose they are most suitable. At any rate, it is a termite-proof wood, and despite the fact that the white ants often attack the growing tree, they usually eat only the outer bark, leaving the tree quite intact and alive.

In all, about 300 acres have been planted with teak, and even at the low valuation of the cost of making them they are worth at least £45,000. In this case a nominal value of only 3s. per cubic foot is assumed. As has proved the case in Burma, probably on the best soils only a period of eighty years will have to elapse before the final filling of the trees is made on the better classes of soil, and one of a hundred on the poorer soils. At approximately regular intervals of every ten years after the first ten or fifteen have elapsed from the date of the making of the plantation, thinnings are made. With each succeeding period the trees cut out are of larger size, and thus of increasing value with each decade. These returns soon more than cover the cost of planting, and assume greater and greater proportion towards the end of the rotation.

Another tree with which a considerable amount of work has been done is the Iroko (Chlorophora excelsa). Here, despite many disappointing results, care and attention show that this tree is capable of reproducing itself in a comparatively short period. Beyond many specimens in the Arboretum at Olokemeji, a whole plantation was made by the Railway between that place and Eruwa Road. Seedlings come up in large numbers from fresh seed sown in a nursery. In fact, sometimes, as at Olokemeji, they have appeared thicker than grass. Subsequently, when transplanted, many thousands died, the roots being apparently unable to quickly adjust themselves to new surroundings and grow again before the leaves have transpired nearly all the moisture from the plant, and thus quite withered and dried it up. However, those which have survived show fair growth, even on poor laterite soil. This soil, of course, is quite unsuited, and certainly one of the poorest mediums in which to plant Iroko.

Natural regeneration or the sowing of seeds at stake seems to be the best method, as we have in nearly all the Reserves large numbers of young Iroko seedlings of all ages and sizes coming up. In that connection one of the most instructive Forest Reserves is that of Ikrigon, where the Iroko (Chlorophora excelsa) is the most prevalent tree. Here, where most of the land has been farmed at one time or another and where the rainfall on the whole is sufficient to induce a good forest growth, the Iroko has tended to increase in numbers all through this part of the country. It may also be said, of course, that the natives have directly helped in this process, by leaving some of the less straight and more branched Iroko-trees standing. They have used the best for canoe-making. In this manner seed-bearing trees have been available, and with part of the ground having been cleared for farms, the conditions have been most suitable for the reproduction of the tree. Subsequently the farms have been abandoned and the young trees have grown up amongst the weeds, creepers, and other inferior tree species, such as Albizzia, just according sufficient shade and protection for the young Irokos, and yet not too dense or thick to prevent them from sooner or later emerging and overgrowing the rest of the trees. Although, of course, many trees growing up under these conditions branch somewhat low down, they do not suffer nearly to the same extent, and sometimes not at all, from the attacks of the leaf coccus. This has two effects: not only does it not hinder and retard the sapling’s growth, but also all the sooner it reaches the higher zone or greater distance from the ground (as far as its upper foliage is concerned), so that these attacks do not occur. Again, the competition of the various weeds, Albizzias, creepers, etc., has the effect of so stimulating the growth of the young Iroko that in such positions it reaches a much greater height in a quicker time than when planted in pure plantations. From numerous observations it appears that after the first year the height growth may exceed 6 feet in one season. Even later this is kept up, and if the rest of the forest growth remains comparatively thick, no side branches can be formed on the bole of the Iroko, so that clean-stemmed trees are the result. As it gets older the Iroko stands less shade, and thus any small branches which do form are soon killed by the surrounding trees. Thus it is seen how we find these very straight, long-boled Irokos in the forests. Again, too, it is not very expensive, and at least much cheaper, to undertake partial cleaning and pruning amongst the self-sown Iroko-trees, especially to eliminate forks low down in the stem. Various experiments undertaken in the Ikrigon, Olokemeji and Mamu Reserves showed how quickly the sapling Irokos respond to this treatment. In some cases, trees only 2 inches in diameter and forked have reached nearly 4 inches in diameter and nearly doubled in height in one year. Another advantageous feature of the Iroko is the rapid, satisfactory, and smooth way in which the occlusion of the wounds made by pruning takes place. Even in the case of a very crooked tree covered with several branches, in fact almost forming a crown, these may be marked but not all cut until the following year. Surfaces of less than 2 inches will be nearly occluded over, and a tendency of the tree towards a crown will be almost obliterated at that point and be forming much higher up the tree.

Apparently, the more northward the tree is found the less liable it is to attack by the leaf coccus. Whilst it is found in the Olokemeji, Ilaro and Mamu Reserve, it is less frequent in the Ikrigon Reserve. In the Sokode it was quite unknown. This last-named place is in Togo, and the plantation is situated in a latitude of over 9° North.

In the Ilaro and to a lesser extent in the Mamu Reserve it has been remarkable how rapidly the Iroko increases in girth when given plenty of space after being freed from the surrounding forest trees. In these trees, when showing a girth of from 4 to 8 feet, the diameter increment is most rapid. In most cases it averages over 6 inches in girth, and in one case at Ilaro it was as much as 11 inches in one year. This rapid growth in girth is all the more valuable as the trees of this size growing in the high forest have usually nearly completed their height growth. Thus the bole is comparatively long and clean, and the extra growth is put on evenly all the way up, tending to make it more cylindrical than before.

With the protection of the forests alone as Forest Reserve both in the evergreen and mixed deciduous forest zone, not only are many Iroko-trees preserved and allowed to grow to their full size, but also large numbers of self-sown seedlings come up in the abandoned ground and augment the value of the forests. This is an additional reason why the farming in a Reserve cannot be continued for any length of time. The old farms become more and more filled up with valuable young Iroko-trees, which would be at any rate damaged, if not killed, by the farming operations.

Even without taking into consideration the number of planted trees, the Forest Department has practically guaranteed certain future quantities of Iroko timber in the number of small trees which have been preserved and the potential value of the little ones grown up since the Reserves were made. Only in one part of the country is this anything like the case, and that is in the Ahoada district, where the natives use the Iroko-tree as a boundary mark between the different village lands and also between many farms. To a minor extent this can be seen in the Onitsha district, where the Iroko-trees have been preserved inside the villages, thus giving them the appearance of being the woods of the country while the rest of the land is bare. It is, however, just the reverse. They form the towns and villages amongst the trees, which are thus preserved from the axe and fire of the local farmer. Despite the fact that a fair number of large oversized Irokos have been cut each year in the Olokemeji Reserve, there are many more of the smaller size now coming on than were in existence when the first fellings took place.

Another tree which has received a considerable amount of attention is the Cigar-box Cedar (Cedrela odorata), and to a lesser extent the Toon (Cedrela Toona). Although both are exotic trees, the former especially shows very quick growth. Despite the unevenness with which it is liable to come up from seed, the rapid growth of the tree soon compensates for this disadvantage. In three or four years it may be from 18 to 24 feet high and 8 to 16 inches in girth. Both the largest individual specimens as well as plantations are found in the Olokemeji forest as well.

More in place in the firewood plantations near Lagos and Ibadan is the Casuarina (Casuarina equisetifolia). At Olokemeji this tree has only done comparatively well. Also an exotic, it is most useful for planting near the sea-side on sandy soil, and in places with a smaller rainfall. It will also stand a comparatively dry atmosphere. The wood of this tree is very hard, almost like Ironwood. It is sometimes known as the Australian Beef Tree. Its numerous small branches on the stem make the wood rather knotty and of less value for general construction work. However, its heating power as a firewood is very great. Amongst all the forest trees it is one which yields the greatest amount of acetic acid, which forms the basis of an explosive.

Another Australian tree which has been used to a lesser extent for Afforestation purposes is the Blue Gum of various kinds. Eucalyptus citriodora and E. amygdalina have proved to grow the quickest of any planted in Nigeria. Many others have been tried, but most have not survived. Specimen trees and small groups are seen as far apart as Onitsha, on the banks of the Niger, Ikassa, near the mouth of the Nun branch of the Niger, the Botanical Gardens, Calabar, the Olokemeji Arboretum and Forest Plantations, not to forget the streets of Lagos. In a similar way Casuarinas are seen near Government House at Calabar and in Lagos, besides the forest Arboretums and plantations.

Another exotic from India, Lagerstrœmia (Lagerstrœmia flos Reginæ), has grown well both on the banks of the Ogun and on poor laterite soil of the Olokemeji Forest Reserve. For the sake of the flowers alone it is worth planting to ornament a garden or the edge of a plantation. The masses of mauve flowers last a considerable time and blend most beautifully with the foliage and any green grass near by. Although of branching habit when planted 10 feet apart, if planted closer it will grow straighter and with cleaner bole. The timber is hard and very durable. So far this tree has proved a valuable introduction, especially for planting poor soils and river banks liable to inundation.

A later, though an exceedingly good introduction is that of the Satinwood (Swietenia chloroxylon), which gives promise in the Olokemeji Forest Reserve of making a valuable addition to the number of timber trees of indigenous and exotic origin. This tree yields the Ceylon satinwood, which is usually worth at least £12 per ton. The almost silvery-white tufted formation of the leaves is reminiscent almost of the Eucalyptus, though the leaf is rather smoother and not quite so narrow in proportion to its length as most of the Eucalyptus family.

Some years ago the seeds of Pinus Mercusii were planted in several places, including those of higher elevation. Although it many cases the seed germinated, the seedlings subsequently died.

Another exotic, the Swamp Cypress or Bald Cypress, or, as it is known in England, the Deciduous Cypress (Taxodium distichum), was tried near Benin City some years ago for swamp planting. Here, as in the other case, the seeds germinated and the small trees reached the height of about a foot and then subsequently died. The swampy ground where they were planted may, however, have been rather too acid or sour for them. The climate, of course, was no doubt considerably hotter than that of the Southern States of the United States, in which country this tree is indigenous.

The original Spanish Mahogany, or Swietenia mahagoni, was intended for Afforestation purposes with a view to its yielding on the average a more highly valued wood than that of the African Mahogany. However, in Africa generally, and in the Olokemeji Arboretum, it has proved a very slow growth and more liable to attack by the leading-shoot borer than even the indigenous mahogany-tree.

For the comparatively dry laterite soil of the Olokemeji Forest Reserve, Indian Rosewood or Blackwood (Dalbergia latifolia) has proved a valuable introduction. Growing comparatively fast and of somewhat branching habit, it soon covers the ground. It is, of course, better in mixture with others in order to produce clean stems. Latterly the larger trees have been attacked by a borer and considerable damage has been done. Still, in spite of it the trees have gone on growing, and apparently are capable of outgrowing the damage without an enormous loss of increment. In all, several acres have been planted with this tree.

Indian Walnut (Albizzia Lebbek) has found a foremost place in the firewood plantation at Ibadan and Ede, as well as in the forest plantations at Olokemeji. Its rapid growth and comparative indifference to soil make it a comparatively valuable tree for Afforestation purposes. Although it is usually only considered suitable for firewood, there is no doubt that its wood can be used as a substitute for walnut, as it is in India. Already, in fact, it is largely a forest escape in Africa, and is found in many of the old farms and cultivated places. Its greyer, almost silvery-grey, foliage easily distinguishes it from that of Albizzia Brownii, which has larger leaves.

A South American exotic, the Lignum Vitæ (Guaiacum officinale), is found in isolated specimens in the Olokemeji Arboretum and forest plantations. With such a very slow-growing tree, which may show half an inch growth in a year, it is difficult to be patient and wait for the many years before it will attain even a size large enough from which to cut the smallest bowl for a game of skittles or bowls. Its very yellow small foliage is most distinctive and not unlike box (Buxus sempervirens), but the leaf is flatter and does not curl like box.

One of the most valuable introductions in the forest plantations at Olokemeji and in the firewood plantations at Ibadan is the Siamese Cassia or Bombay Blackwood (Cassia Siamea). Almost indifferent as to soil and not requiring a heavy rainfall, and casting a heavy shade, it soon grows on the laterite, covers the ground, killing weeds, and rapidly attaining the size of a tree. In the plantations at Olokemeji, the trees reached a height of over 20 feet and a girth of about a foot in five years. It is one of the few trees that will thoroughly kill the Econ grass. The masses of yellow flowers which appear in the crown of the tree and also in the leader rather interrupt the height growth, but make a magnificent show at the end of the dry season. It continues to flower and fruit for the larger part of the year. Either as a firewood tree or as a timber tree, it should always be worthy of a place in all Afforestation areas where the rainfall is none too heavy. The hard, almost black wood is of value in India, so that it should prove of value in Nigeria when the trees are large enough for cutting into planks or boards. Amongst the exotic trees which have not yet found a place is the Trinkomali Wood (Berrya Ammomilla) and Indian Rose Chestnut or Ironwood (Mesua ferrua), seedlings which were obtained from seeds of the large trees in the Botanical Gardens at Victoria. If they grow well in Nigeria, the somewhat heavy and flexible Trinkomali Wood or Petwun and the Ironwood should both prove of value for local industrial work.

Although found as specimen trees in the Olokemeji Arboretum, Copaifera officinalis has not been formed in plantations, though small groups of the West African Gum Copal (Copaifera salikounda) are seen in the Ogba plantation of the Central Circle. Both these trees are doing very well, more especially the latter, which have reached a height of over 12 feet in six years. The former had produced some tears of gum three-quarters of an inch in diameter in the tenth year of its growth. In addition to these two, there is the Cameroon Gum Copal (Copaifera Demeusii), seedlings of which were obtained from the Botanical Gardens at Victoria. Considering that the last-named tree is indigenous in a territory so much closer to Nigeria than either of the first-named Gum Copals, it is highly probable that this one will grow better than either of the others. Up to the present it is not known, however, how the yield of the Gum Copal compares with either of the former. As far as West Africa is concerned, the Sierra Leone Gum Copal has proved to be the most prolific in this respect.

The Indian Almond (Terminalia catappa) is seen more as an avenue tree, mostly in towns such as Lagos, but also in the Mamu Forest Reserve. It is certainly one of the best shade trees for planting at the side of roads. Its rather formal habit, with the almost even whorls of branches, fits in with the straightness and even width of a road. By many it is not realized that the nuts can be comparatively easily cracked and the kernel inside is good to eat.

Michelia champaca is another most suitable tree for avenues. The chestnut-like leaf and the large, almost magnolia-like flowers are of a white colour, giving it a “distinguished” appearance such as is necessary for a roadside tree. The flowers, too, are used for making scent.

Both as a shade tree and for its gum the Balsam of Peru (Toluifera Pereiræ) is also worthy of a place both in avenues and in plantations. Some seedlings were obtained from the Botanical Gardens at Pretoria, where the tree has grown comparatively well. Not so suitable for plantations apparently at Olokemeji is the Sugar Palm (Arenga saccharifera). However, in isolated places small plantations have been made with the Sago Palm (Corypha elata), such as in the swamp opposite Calabar and the small grove of the Betel Nut Palm (Areca catechu) near Lagos. Both these give promise of being useful acquisitions to the palms of economic use in Africa.

Before leaving the exotic trees, mention must be made of the Thuya (Thuya occidentalis), which were obtained from the Canary Islands by Major Cockburn and planted on the hill at Obubra. Although somewhat slow growing, they have thrived in that climate and do not suffer from disease. This is the only example of a Conifer which has been successfully introduced into Nigeria.

Amongst the other indigenous trees of which plantations have been made there is the Cedar Mahogany (Pseudocedrela Kotschyi), Emi gbegiri, Yoruba, which apparently grows but slowly in Olokemeji. It is much the same with the self-sown seedlings and with root suckers, both of which have proved disappointingly slow in that locality.

Then also at Olokemeji we have the dry-zone Mahogany, Khaya Senegalensis, Oganwo of the Yorubas and Ogwangu of the Benis, growing in a small plantation and raised from seed brought by H. N. Thompson, Esq., from the Shaki district in 1910. So far the growth has been comparatively rapid, though the tree is occasionally attacked by the leading-shoot borer, which makes it fork comparatively low down.

Of the African Walnut and the Long-capsuled Mahogany, Lovoa Klaineana and Entandrophragma Candollei, most isolated specimens and groups appear to have been planted in the leased areas of Benin. In addition to these, some other specimens and small plantations are found in the Calabar, Degama, Benin and Olokemeji Arboretums, as well as in the plantations of the Ogba and Olokemeji. Thus far only the Long-capsuled Mahogany has been planted in these; the difficulty of obtaining seed of the African Walnut has precluded its wider distribution in the various plantations. Long-capsuled Mahogany grows very fast, usually with an undivided stem and a big tuft of long pinnate leaves near the top of the tree. Stump shoots form very readily and soon attain a large size, as is noticeable in the specimen in the Benin Arboretum.

The plantations of Ebony (Diospyros mespiliformis), Kanran of the Yorubas, have been made in the Olokemeji Forest Reserve. Although, of course, very slow growing, it demands further attention, as it yields a good black ebony.

Amongst the soft woods there are plantations of Triplochiton Nigericum, Arere of the Yorubas and Obechi of the Benis, in the Olokemeji Forest Reserve. At first growing rather slowly, they bid fair to prove one of the most rapid growing trees. A mixture where teak was introduced to fill up the blanks will be interesting to watch in its future development, as to whether the teak will eventually outgrow the forest maple.

Although the firewood plantations at Ibadan and certain parts of the plantations of Olokemeji have been filled up with West African Walnut (Albizzia Brownii), Ayinre Bonabona of the Yorubas, they will prove probably of greater value for the production of timber than for firewood. However, as a firewood tree it has yielded several cords of wood from one tree after only seven years of growth. So far it has certainly proved to be the tree which produces the greatest amount of firewood in the shortest period of time. It sprouts well from the stump, so that for a time its reproduction is very easy and assured.

The Oil Bean (Pentaclethra macrophylla), Apara of the Yorubas and Opaga of the Benis, is found chiefly reproduced artificially, either by being sown at stake or planted along the sides of the roads in the Owerri and Benin provinces. Considering the hardness of the wood, the tree grows not excessively slowly, though, of course, compared to a softwood it is slow.

Camwood (Pterocarpus Osun), Osun by the Yorubas, Ume by the Benis, has found a place in the Mamu Forest Reserve, its congener Pterocarpus Indicus having been planted in the Olokemeji Forest Reserve. However, as far as the size and habit of growth is concerned, the African Redwood or Barwood appears to be much superior to the Indian Paduak. The latter usually soon develops a triple stem with many small side-branches, whereas the African species always shows an undivided stem. In rate of growth “Osun” seems to be rather slow compared to many other trees. Self-sown seedlings come up readily in suitable localities, such as the Ikrigon Reserve, and on the whole develop more quickly. Anyhow, the continual demand in increasing amounts of this red dye-wood necessitates the careful preservation of the tree in the forest, as well as its continual reproduction by natural regeneration or plantations in the Forest Reserve.

Amongst the Mamu Forest Plantations there is that of African Oak (Afzelia Africana), Apa (Yoruba), Aligna (Benin), one of the few survivals of the efforts made to reproduce this tree artificially. The many insect and rodent enemies give isolated plantation seedlings very little chance to develop.

Although Shea Butter (Butyrospermum Parkii), Emi Ori or Emigidi (Yoruba), has been tried as a plantation tree, the germination of the nuts is very poor, and the rodents attack them unmercifully. Apparently root-suckers form the chief means of reproduction for this tree. They are very prevalent and very persistent once they have sprouted. The forest fires destroy a great deal of the flower in the early part of the year, preventing formation of the fruit, and thus the means of reproduction by seed is very much reduced. The improvement in trees protected from fire at Olokemeji is most marked.

At Degema there is a plantation of Mimusops Djave (?), or Aganokwi of the Benis, which shows comparatively fast growth; in eleven years the trees had reached a height of about 25 feet and a girth of 2 feet 6 inches. Although it sprouts well from the stump, it is easier to raise from seed, but the seedlings require great care in transplanting.

At Olokemeji, Shinglewood (Terminalia Superba), Afara, by the Yorubas and Egoyn Nufwa by the Benis, is being tried in a mixed plantation. The growth has been rapid, and would probably surpass that of teak after the first five years.

Over considerable areas of the Olokemeji and the Ibadan plantations the Yoruba Chewstick, or Ayin of the Yorubas (Anogeissus leiocarpus), has been planted. Its growth has been moderately rapid, reaching a height of about 8 feet in four years. In addition to the value of its wood both as a chewstick and from the fact that a mordant for dyes can be made from its ashes, the young plant kills all the Econ grass growing round it with its leaf fall. This makes the tree one of the most advantageous for Afforestation purposes. Its light-green foliage and delicate, graceful build, and slender bole and branches, make it also valuable as an avenue tree in the dryer parts of the country. In its similarity to the European birch it might almost be called the birch of Africa.

With the Dika Nut (Irvingia Barteri), Oro by the Yorubas and Okherli by the Benis, small sample plots have been made in the Mamu Reserve and isolated specimens planted near the Calabar Arboretum.

Although not for Afforestation purposes but for the production of Palm Wine, Raffia vinifera, Ako by the Yoruba, Augor by the Benis, has been planted and seeds distributed amongst the villagers of the upper parts of the Cross River districts. When these are grown there will not be such a demand for cutting down the oil-palm-tree for making palm wine as there is at the present time.

Allowing only a value of 3d. per tree on all the trees planted during the last fifteen years, all the mahoganies and plantations are worth £240,000.

In two circles and parts of a third a great deal of work of an Afforestation nature was undertaken years before any actual forest plantation could be made. These are the communal rubber plantations of the Ireh Rubber (Funtumia elastica). In the Central Circle, near over 700 villages and towns, plantations varying from a hundred plants to ones covering several acres and containing many thousands, were made, aggregating in all the setting out of over a million trees in a period of about five years. In the Eastern Circle, in over a hundred villages, and in the Ondo and Western Circles over two hundred village plantations were made. Subsequently Para Rubber (Hevea Braziliensis) was added and substituted for the Funtumia wherever the climate was suitable for it. Now the communities concerned have a very valuable asset, which they can tap from year to year and augment at their leisure. Whatever happens to the forest or the immediate neighbourhood of the village, there will at any rate remain the rubber plantation, giving grateful shade to the roadsides and the ground near the villages. In one case a village planted over 1,200 Para rubber-trees, which even as a commercial asset are by no means to be despised.

In addition to these efforts on the part of the natives, acting under the advice and guidance of the Forest Department, there are the numerous rubber plantations in all the Forest Reserves. In the earlier days these were planted with Funtumia, where, for instance, in the Mamu Forest Reserve nearly one square mile of land is planted with this tree.

Then, again, there are the district plantations, more especially in the Eastern Circle, where in many cases Para Rubber was planted instead of Funtumia. These areas are for the most part smaller than those of the Forest Reserve or Communal Plantations. They served more as demonstration areas to show how rubber would grow in that locality.

Furthermore, near almost each native court in the Eastern Circle rubber plantations, in many cases of Para and in others of Funtumia, were made.

The general cost of the Communal District and Native Court Plantation was practically limited to the amount involved in payment of the native Forest staff. These men, however, had other duties to perform, and on the average certainly not more than one-third of their time was occupied in the making of these plantations. For the making of the other plantations of the Forest Reserve about £2,500, or sometimes £3,000, has been spent annually in making them and in the cost of their upkeep once they have been made. Owing to the long dry season in Nigeria the number of plants failing to survive it is somewhat high, and this very considerably increases the cost of the final establishment of the plantation. For some years the cost in many cases amounted to £10 per acre for the first year and £1 or £2 for subsequent years, for the cost of “beating up” and keeping the plantations clean. With the greater experience gained both in regard to the habits of the different trees and in the methods of reproduction most suitable to various parts of Nigeria, the cost has been somewhat lessened. However, even so, the cost compared to European or English plantations is not abnormally high. In Africa there is no land to buy, and no wire-netting is needed for the plantations, and the land usually planted has not a “letting” or “sporting” value, as it has in England. The buying out or compensating of the native rights of the usufruct of the soil is not so very expensive, especially when it is spread over comparatively large areas, as it usually is in West Africa. Then, again, even with the cost of £10 per acre, the total value of a crop after fifty or sixty years would certainly not be less than 3s. per cubic foot of the timber, which thus allows ample margin for 5 per cent. compound interest on the original outlay, and a profit besides. In many cases the timber would be worth a great deal more, and also the value of the intermediate thinnings is not inconsiderable. Both these factors have been left out of the account, in order not to in any way exaggerate or make too optimistic estimates of the value of a forest plantation. But beyond the financial side of the value of forest plantations, more especially in a tropical country like Nigeria, is the very valuable indirect effect they have on the whole welfare of the country.

First of all, plantations in forest groves improve and beautify a locality, whether on the level or amongst hills.

In the second place, the forest induces a greater rainfall in itself and its immediate vicinity.

Then the rainfall which actually falls in the forest is partly re-evaporated to fall again, thus making extra rainfall, and also the rain which actually reaches the ground in the forest is only gradually absorbed, thus making the flow of springs and rivers regular.

Both on the level and especially on slopes, a covering of trees, such as a forest, hinders the washing away of the surface soil or tilth of the land.

Forest trees only require one-twelth of the mineral matter out of the soil that an agricultural crop does, covering the same area.

In a forest plantation there is always greater humidity in the air, and thus many plants of economic value, such as cocoa, can grow in its vicinity, which would otherwise not be possible to be grown in that locality.

A forest acts as a moderating influence on the temperature of the air, being lower inside the forest than outside, when the sun is very hot. Conversely, when it is cold outside in the “harmattan” season it is warmer in the forest.

Nearer the interior of the forest certain better grasses and pasture are found, which are of incalculable value, in a drought, to the cattle in that locality.

During the long period of the rotation, usually at least 60 or 80 years, in most forests there are large accumulations of leaf mould or litter, which on occasion can be used in reasonable quantities for manuring neighbouring agricultural lands. This is of incalculable benefit where the ground outside the forest is comparatively poor and dry.

It has been proved also that in these long forest rotations the mineral rock and subsoil have time to weather, and add further mineral matter to the enrichment of the soil.

The forest, too, provides grateful shelter and sanctuary for game animals and birds of all kinds, thus providing, especially in Africa, the largest source of meat which the native has.

When all these indirect advantages and good effects of the forest are added together and a definite value put on them, and then considered in addition to all the timber and firewood the forest produces, it will be seen how wonderfully and providentially beneficial the forests really are, and also how absolutely essential they are in a country like Africa.

Just as effective, and cheaper, except perhaps as regards time, than the artificially made forest plantation, are the protected forests; even in the worst case, starting with a poor country growth and small dry-zone shrubs and trees, after ten years there is a compact, close-growth, medium-sized tree with straightened stem and less branching habit, and the ground comparatively free from grass. During a further period this forest can be thinned out by removing the poorer shrubs and trees and allowing seedlings of more valuable species to come up. They will often do this in the shade of poorer and more hardy trees. Still later, as the soil-moisture conditions improve, the humidity increases as well as the rainfall; still other species come in or can be introduced artificially. Eventually, by the end of the first rotation there is probably quite a different forest to that in existence at the time of the annual grass-fires, and one which is more akin to the original forests before the advent of Man with his firestick.

Quite apart from any money which has been spent on direct forest plantations, the indirect effect of the protection afforded to the trees in the various forest reserves is of almost incalculable value. If the figure should be calculated out even at a low rate of only £1 per acre, then the total value is £768,000 for the Reserves already made. Again, considering this result has only been attained after about fifteen years’ work, it will only go to show the vast potentialities and resources that may be eventually created, or preserved from destruction, in Nigeria.

V. The Forest Department.[3]

European Forest Officers are of two ranks, the scientifically trained Conservators of Forests and the executively trained Foresters.

The scope of this paper will only cover the former, as very few of the latter are Europeans, and most of them Nigerians.

From Oxford, Cambridge and Edinburgh, graduates in Forestry can usually be procured. The training at these centres covers roughly a year or a year and a half’s work on the elementary subjects, such as Botany, Mathematics, Geology, Mensuration, Surveying, and Political Economy. In addition, a year or two years’ work on the professional subjects, Silviculture or the growing of Forests, Forest Protection, Forest Utilization, Forest Botany, Forest Entomology, Forest History and Forest Policy is required. At the end of the course, six months’ practical work in Scottish or English forests follows, during which period working plans and market conditions are especially studied.

After being accepted for appointment in Nigeria, a further three months’ course is taken at the Royal Gardens, Kew; and six months’ practical work on the Continent was (before the war) usually required. At Kew, the object is to acquire a working knowledge of the most important Botanical Orders which contain the African trees. The continental course shows the student forests which have been under a definite scheme of management for over a hundred years. It takes one, in fact, right through the life-history of a tree from a seedling in the nursery-bed to the well-grown financially mature tree, marked ready for the axe, a period of about eighty years.

The initial appointment is for three years on probation, after which it may be confirmed. The initial salary of an Assistant Conservator of Forests is £300 per annum, rising by increments of £15 to £400 per annum. The first appointment dates from the day of sailing, the passage being paid by the Nigerian Government, and salary on half-pay begins from the date of departure until the arrival in Nigeria, when full salary begins to accrue. Intending candidates should bear in mind that an early selection for appointment entitles them to seniority over other candidates who, owing to their being fully qualified, are appointed immediately, and thus reach the Colony before them. Locally, a commuted travelling allowance of £42 per annum is drawn to compensate for the extra cost entailed in inspecting the forests. A limited number of carriers, or other means of transport, are provided by the Government. For the purpose of more rapidly getting about, a bicycle, motor, or horse may be kept, and an allowance is given for maintenance. The cost of living is high, even when furnished quarters or a bungalow are provided.

Lagos is the first port of call in Nigeria, and there is a railway journey of 123 miles before reaching Ibadan, the temporary headquarters of the Forest Department. Olokomeji, 90 miles from Lagos, is the old headquarters, and from here the forestry work of the Southern Provinces is directed. Zaria, situated some 450 miles from Lagos, is the headquarters of the Forestry Department in the Northern Provinces.

A newly appointed officer would be liable to be sent to either of these last-named places; but owing to the larger number of men being stationed in the Southern Provinces, the majority are sent to that centre. Olokomeji is in the middle of a Forest Reserve 26 square miles in extent, and is also the headquarters both of the Western Circle and of its northern division. In each circle there is a Conservator of Forests in charge, and he has an assistant to manage each division. In the event of a shortage of staff it may happen that a new man is put in charge of a division and thus has an opportunity of learning all about the work much more quickly than would otherwise be the case. In the ordinary way he only corresponds with his Conservator and the timber interests of his division on purely local matters.

Since 1901, a moderately large Arboretum has been planted at Olokomeji, containing quite a number of indigenous trees growing under natural conditions, according to the type of climate found in that locality, and also some exotic trees which grow in similar climates in Asia or South America. In a comparatively short time the new Forest Officer can get a very fair idea of the most important timber trees found locally, as well as elsewhere. In connection with the work of renewing the labels on specimen trees, ocular demonstration of all these trees is obtainable. The local Ranger can usually supply the vernacular names, and here is a wide field for linguistic qualifications. Yoruba is the local language, Benin is spoken by a large number of people in the Central Circle, and Hausa by nearly all itinerant traders throughout the country. Ibo, another language, is spoken by nearly 3,000,000 inhabitants, while many of the Cross River people (Eastern Circle) speak Efik; some, however, speak New Calabar or Ibibio, while again, in a large part of the Niger Delta, Brass or Ijor is spoken. Sooner or later the language of the locality should be acquired, and in fact this is prescribed by Government order as a necessary preliminary to the granting of the first increment.

The routine office work includes simple book-keeping, analysis of records, appointments of staff, the engagement of native labour and all payments. The executive work outside is carried out by the Forest Guards, Foresters, and Rangers, who require constant supervision. Owing to the distance, only some of them can report at Forest Headquarters each month, and the rest must be seen when the Forest Executive Officer makes his tour of inspection. If possible, travelling should take the place of indoor work for at least ten days a month.

At first sight, on examining the tropical forest, it appears like a very mixed collection of different kinds of trees; on closer inspection, however, similarities and contrasts are apparent, such as Ebony, Diospyros mespiliformis, with its thin, black scaly bark, and that of the somewhat regularly, deeply fissured bullet-wood tree, Mimusops multinervis, and its white latex, which the former does not exude.

In walking through a forest, it is normally best to make the carriers precede. Owing to their tendency to lag, and their desire to sit down at inconvenient times, it is an advantage to have them in front. Frequently one may have to stop and examine a flower or leaf, and it only adds to the carriers’ labour if the whole column has to stop whilst seeds and specimens are being collected. A march of about 15 miles is sufficient, and takes up the better part of the day, if an examination of the forests is being made on the way. In most parts villages are eight to ten miles apart, sometimes nearer; so the carriers can stop and purchase food. In the larger forests, however, a distance of over 20 miles is sometimes covered without sight of a house; in that case the people of the last village are asked to bring food for the carriers, and the carriers themselves are given a day’s food as well, which has to be cooked on reaching camp. In some places the chiefs provide food (yams, etc.), which is distributed to the carriers, or in some places 3d. a day per head is allowed them for purchasing food. So long as the carrier gets food and his load is not excessively heavy, he is quite cheerful and walks well. He will pick his way in mud, over roots, and up the steepest rocks in the hill forests.

Current wages vary from 9d. to 1s. a day, the head-man getting from 1s. to 2s. a day. Local felling-permits being issued both by the District and Forest Officers to natives for felling timber for local use, at District Stations a call is paid the District Officer to discuss current forest questions and examine the permit books. At the same time there is an opportunity of seeing what further development of forest work is possible in the district. The local Forest Guards, Foresters, or Forest Rangers report themselves, usually giving a very good account of the local forest conditions. Since the demand for local timber has been growing, a stop may have to be made to supervise the marking or girdling of suitable trees for bridge-building under the auspices of the Public Works Department. On a journey through the mahogany forest, the different camps of the timber firms have to be visited. These firms have hundreds of square miles for the purpose of exploiting mahogany and furniture woods. At the same time the checking and inspecting of the stumps of all the trees felled has to be gone through. The young mahogany seedlings are also seen, and from the number of these it is known whether sufficient have been planted to take the place of those cut down. The very rapid growth of these trees can here be studied to advantage; trees now 40 feet high have only been planted a few years. The relative value of the direct planting of seedling trees as compared with the natural regeneration of the forest by self-sown seedlings can be observed with ocular clearness. In one part of the forest one sees natives standing on a platform hacking away with an axe into a huge 50-feet mahogany; in another place a similar tree, fallen, its 90-feet bole already sawn into three round logs: while in a third locality may be seen a native, axe or adze in hand, squaring mahogany logs with a 4-feet side. Later in the season eighty or more natives are engaged in dragging one of these logs on round billets of wood (for rollers) along a track, roughly cleared to the height of a man, to the nearest natural water-way; still later (that is, in July or August), when the rivers rise, the logs may be seen floating singly down to the rafting-place on the main creek, where rafts are made with logs four or eight abreast, each fastened to the next, from a timber-dog at either end, with cane. From here, riverine natives such as the Ijors take the logs to the nearest river or ocean-going steamer port.

The administrative work of the Department is in the hands of the Senior Conservators of Forests, under whom the Conservators manage their circles. The Chief Conservator of Forests, the head of the Department, initiates and controls the whole policy of the Department, being relieved of all details of administration. In order to ensure continuity of policy and action, a Working-plans Division has been formed. A working plan for the forests is a scheme of management laid down for a number of years; no change can be made in such a plan without special reference both to the head of that division and to the head of the Department. With only one year’s service, followed by leave of absence, continuity of action would be broken if it were not for a definitely approved plan.

The Forest Department has supplied the Railway, Marine, and Public Works Department with timber of various kinds. In some cases the timber is obtained by departmental working, and in others is cut by native contractors under the supervision of the Department. In the first instance, the conditions under which timber is to be supplied to other departments are put before the Secretariat, and when once the work has been begun, the local Forest Officer deals direct with the department concerned.

Forestry progress in Nigeria has been less tardy than in several other Colonies, though many forests have been destroyed owing to lapse of time before the formation of a department. In 1904 there were eight, and there are now twenty-four administrative appointments. The amalgamation of Northern and Southern Nigeria into one administration should accelerate the development of Forestry. It is as yet only in its initial stages, and scarcely more than a thousand square miles of forests, out of nearly a hundred thousand which exist in some form or another, have been permanently set aside for further timber production. The revenue-earning capacity of the Forest Department has been somewhat diminished by the war; but with recent legislation more local revenue should be obtained, which should more than off-set any loss already sustained. Provided the financial position of Nigeria remains strong, the prospects of the Forest Department are quite bright.

Although Nigeria has by far the largest Forest Department, very similar conditions of service obtain in the other West African Colonies of the Gold Coast and Sierra Leone; but there are no Forest Officers in the Gambia.

VI. A Review of the Botanical Features of Northern Nigeria.

By Dr. J. M. Dalziel.

The Northern Provinces of Nigeria exhibit in an interesting manner the transition, now familiar in West Africa, of physical characteristics from the tropical forest to the border region “that just divides the desert from the sown.”

So far as the progressive stages may be stated in terms of geographical latitude, we may place the northern limit of the forest belt at about 8° North latitude. A convenient natural boundary in a portion of the area under consideration may be accepted in the lower course of the Benué River from its tributary, the Katsina River, or even as far up as Ibi, to the Niger at Lokoja. On the other hand, the southern limit of the desert is taken at about 17° North latitude, or higher, and thus falls some three or more degrees beyond the northern boundary.

Between these arbitrary limits lies the greater part of Northern Nigeria and practically the whole of Hausaland, presenting physical features which vary through grassy plains and rolling downs, orchard-bush and thin-crowned forest, laterite plateaux and hilly woodlands, to the mountains of the Bauchi Highlands. The vegetative covering over a very large area can be classed as one or other type of savannah, tree and bush savannah, or open orchard and treeless savannah, with intermediate grades. Local topography alters the type here and there, galleries of evergreen vegetation occupying the intersecting belts of permanent streams or fringing a marsh, wide meadows bordered by low forest, but occupied entirely by grasses of few species, with scattered islets of foliage, or, again, outcrops of bare laterite and isolated domes and turtle-backs of crystalline rock, “inselbergs” and “kopjes,” introducing features of their own.

The Niger Delta displays admirably the high evergreen or moist tropical forest. This probably connects itself through the Kameruns with the great Central African forest of French and Belgian Congo, which is again said to be continuous through the gap between Ruwenzori and Lake Albert with that of British East Africa.

West of the Niger Delta the coast, including Lagos, Dahomey and Togo, is sandy, and bush rather than high forest commences almost on the shore. Ascending the Niger, one finds that the true “rain forest” ends, but not abruptly, in the neighbourhood of Asaba; a gradual transition occurs, first to an intermediate type, partly evergreen with many large trees, but mingled with those that lose their leaves in the months of little rainfall. This change is apparent even on the river-bank, and below Lokoja a more open but still semi-evergreen forest clothes the valleys, but shows already more of the deciduous element on the hills. Farther north the voyage from the mouth of the Kaduna River to the Zungeru light railway terminus at Barijuko, as often experienced in previous years, reveals again the progressively deciduous character of the foliage, resulting in a still more open forest.

The river-bank, however, possessing permanent moisture and its own local climate, is an inadequate index of the general features over the country at large. To travel by land from Baro to Zungeru, and thence either through Kontagora to Sokoto, or by Zaria to Kano and Gummel, is to have the complete vision of the West African savannah in its various degrees, and, except for local interruptions associated with considerations of altitude or geological outcrop, etc., or with the lines of perennial streams, to have it in its regular sequence.

Leaving out of account for the present the region south of Lokoja and of the south bank of the Benué, which in part represents the “Zone Guinéenne” of Chevalier, we find that the two routes suggested above will take one through country almost entirely of the types included by the same writer within the “Zone Soudanienne,” with an approach at places along the Anglo-French boundary to the conditions occurring in his “Zone Sahélienne.” It would be difficult and misleading to express these zones definitely in terms of latitude, but one might hazard the statement that the Guinea Zone passes to the Soudan Zone somewhere between 8° and 10° North, and the latter extends either to the northern boundary or verges on a drier belt beyond the latitude of 12° or 13° North. If a complete botanical survey were possible, one could then subdivide each belt into its different areas and provinces, with their special floral characteristics, but at present one must be content to indicate broadly the general composition.

The Soudan Zone, indeed, includes the greater part of Hausaland and is representative of the typical West African savannah and savannah forest. It merges into the drier sandy “steppe” conditions in the north and into the mixed deciduous and semi-evergreen forests farther south. The only giants in height are the silk-cotton-trees (Eriodendron orientale), but baobabs of enormous girth are common, and the largest timber trees are probably the Maje (Paradaniellia Oliveri) and the Kawo (Afzelia Africana), fair specimens of the dry-zone mahogany, Madachi (Khaya Senegalensis), occurring also in favourable situations.

Across the central part of Northern Nigeria, let us say from Kontagora and South Sokoto through the whole of Zaria and South Kano to South Bornu (but excluding the Bauchi plateau, of which I cannot speak from personal knowledge), the plants named in the list here given might be regarded as the average association of species, trees, shrubs and herbaceous, the chief Natural Orders being represented as follows:

Solanaceæ by the “Thorn Apple,” Datura Metel, by numerous species of Solanum, some edible, e.g. the several cultivated varieties of the native bitter tomato, Gauta, varieties of S. Melongena; others poisonous, e.g. Gautan kura, Solanum incanum, and others; also by two common weeds of the genus Physalis, and the popular herb simple, Dandana, Schwenkia Americana.

Scrophulariaceæ by Scoparia dulcis, of world-wide distribution, and by several parasitic species of Striga, of which the most familiar is the Makasar adwa, S. Senegalensis. Besides numerous humble weeds of cosmopolitan genera, e.g. Moniera, Ilysanthes, etc., mostly occurring in damp places, two or three species of Sopubia may be taken as characteristic of the bush-lands.

Acanthaceæ by a variety of weeds, etc., of the genera Blepharis, Monechma, Justicia, etc., to which the following may be added as characteristic of the Order in Hausaland: Nelsonia campestris, a soft herb of slightly acid taste, Peristrophe bicalyculata, an occasional fodder plant, and Dyschoriste Perrottetii, the mucilaginous seeds of which are used to remove spicules from the eye.

Pedaliaceæ by the locally cultivated Ridi, Sesamum Indicum, and other wild species of Sesamum, by the weed Ceratotheca sesamoides, and by the half-shrubby Rogeria adenophylla.

Aroideæ by Culcasia scandens, by the Kinchia with yellow rhizome, Stylochiton Dalzielii, Amorphophallus Barteri and A. dracontioides, Anchomanes Dalzielii, and other species.

Cyperaceæ by very numerous species of Cyperus, e.g. the edible Aya, C. esculentus, and the uncultivated Aya aya, C. rotundus, C. Fenzelianus, etc., and several of Pycreus, Fimbristylis, Kyllingia, Bulbostylis, etc.

Gramineæ by the predominant tribe, Andropogoneæ, with numerous other genera—Eragrostis, Aristida, Digitaria, Pennisetum, Chloris, etc., and by a single locally distributed bamboo, Oxytenanthera Abyssinica. The chief cereal is Guinea Corn, Dawa, Sorghum vulgare; both species of sugar-cane, Rake, Saccharum officinarum, and Takanda, Sorghum vulgare, var. saccharatum, are cultivated.

The Filices are poorly represented by the widely distributed Adder’s Tongue, Ophioglossum vulgatum, the water-fern, Cratopteris Thalictroides, by Adiantum lunulatum, A. Schweinfurthii, and a few species of Nephrodium asplenium, etc., by no means typical of the region.

Having thus given a bird’s-eye view of the floral composition in the central region of Hausaland, one may proceed to examine the variations revealed in passing south to the semi-evergreen forests and north to the drier open savannahs.

Southwards the transition is gradual, and nowhere abrupt, from forest savannah with annual bush-fires and consequent tendency to revert to grass, to forests in which the number of species is greater and the deciduous element is more mingled with evergreens, either by the persistence of species which in a drier region are deciduous, but retain their foliage where the increased rainfall allows of this variation, or by the appearance of species which always possess the evergreen habit. Bombax buonopozense is an example of the former and probably also Afzelia Africana and several others.

Some of the added constituents either absent from or more rare in the area of lesser rainfall are:

Anonaceæ: Xylopia parviflora, Hexalobus Senegalensis, Popowia Mannii.

Capparidaceæ: Ritchiea sp., Capparis viminea, etc.

Bixineæ: Oncoba spinosa.

Sterculiaceæ: Cola laurifolia.

Rutaceæ: the Fasa kwari, Zanthoxylum Senegalense.

To face p. 196.

Leguminosæ: Tetrapleura Thonningii, Piptadenia Africana, Erythrophlœum Guineense, Cynometra Vogelii, Pterocarpus esculentus, Dialium Guineense, Millettia sp. near M.

Bignoniaceæ: Spathodea campanulata.

Acanthaceæ: Acanthus montanus, Asystasia Coromandeliana, etc.

Verbenaceæ: Vitex chrysocarpa and V. Angolensis.

Piperaceæ: Piper umbellatum and Piperomia pellucida.

Gesneraceæ: Streptocarpus nobilis.

Moraceæ: Chlorophora excelsa, Ficus Vogelii and other spp., Myrianthus serratus.

Ulmaceæ: Trema Guineensis.

Ampelideæ: Leea Guineensis.

Polygalaceæ: the cultivated Polygala butyracea and the dwarf species, P. Clarkeana.

Balanophoraceæ: the root-parasite Thonningia sanguinea.

Amongst Monocotyledonous Orders the Scitamineæ are more in evidence, Palisota thyrsiflora (Commelinaceæ) appears (along with a Begonia on moist rocks—B. rostrata), and the water-loving Aroid, Cyrtosperma Senegalense.

The Oil Palm, Elæis Guineensis, becomes locally common, ferns become epiphytic, and the Elk’s-horn fern, Platycerium Æthiopicum, appears.

Northwards the savannah forests, with plenty of broad-leaved trees and shrubs, or the open park-like formations with surface well covered with grasses and herbs, give way in some places to still drier Acacia forests, and in others to open areas of scrub, nearly treeless, the soil possessed by grasses and low, scattered shrubs, often thorny. Nevertheless, good pastures are often to be found, frequented by the Fulani in the comparatively short rainy season, and only at some points towards the French boundary do the conditions approach those described by Barth in the latitude of Zinder and Timbuctoo. For example, part of North Bornu, with a rainfall sometimes not exceeding 10 inches, may exhibit features entitling it to rank with the upper region of Chevalier’s “Zone Sahélienne.” A typical association in these scrub regions is familiar to the Hausas in three of the plants mentioned below, viz. the Sabarra, Guiera Senegalensis, the Magariya, Zizyphus jujuba, and the Dashi, Balsamodendron Africanum. Sokoto, with an average rainfall of 25 or more inches, still possesses thinly treed savannahs and bush-lands, with a vegetation composed of grasses, small sedges, low shrubs and the commoner leguminous and other weeds.

Nor does the transition occur evenly across the whole region. In the eastern part between Kano and North Bornu the Acacia type prevails, and whole areas may occur occupied largely by Acacia Seyal, with yellow or rusty ochrey bark. On the western side Acacias, though present, do not appear to prevail, and between Kano and Sokoto there exists a stretch of broad-leaved forest in which most of the species found in Central Hausaland reappear, but after all these differences may be found to hold only over limited areas.

The wide and well populated circle around large northern towns, highly cultivated and more or less stripped of trees to supply fuel does not quite display the natural conditions of the bush, where uncontrolled fires prevent natural regeneration of forest on cleared land, and where open grassy formations with stunted vegetation tend to encroach on the higher types of tree savannah.

The species more characteristic of the northern drier belt within the Soudan Zone—if an arbitrary limit is allowed we may place it about 12° North latitude—may now be briefly indicated, though it will be understood that many of them are already present farther south.

Capparidaceæ: most of the species of Capparis, Boscia and Mærua existing farther south here prevail; the low shrub Boscia Senegalensis is common, while Cadaba farinosa is a characteristic shrub.

Simarubeæ: the Aduwa, Balanites Ægyptiaca, is a typical species of this region.

Burseraceæ: the Dashi, Balsamodendron Africanum, a shrub yielding African Myrrh, is familiar, with its congener B. pedunculatum.

Rhamnaceæ: the Kurna, Zizyphus Spina-Christi, usually planted in towns, the Magariya, Z. jujuba, and the Magariyar kura, Z. mucronata, the last two being very characteristic of the open savannah.

Anacardiaceæ: the Danya, Spondias sp., a fair-sized tree with yellow, plum-like fruit having a leathery rind, is abundant.

Leguminosæ: Acacias are the most typical, but are not as a rule markedly flat-topped, e.g. A. Seyal, A. Senegal, A. albida var. saccharata, Dichrostachys platycarpa, forming thorny thickets, while Entada Sudanica, Acacia Sieberiana, A. campylacantha, Albizzia Chevalieri and others are also evident. Parkinsonia aculeata is found in towns; the Tripoli or Senegal Senna, Filasko, Cassia obovata, is common, and the Tsamiya, Tamarindus Indica, becomes a predominant tree.

Rosaceæ: the Ginger-bread Plum, Gawasa, Parinarium macrophyllum, is more familiar.

Combretaceæ: the Geza, Combretum sp. near C. altum, a shrub or small tree, with several gum-yielding trees of the same genus; the low shrub Sabarra, Guiera Senegalensis, is perhaps the most typical plant of the nearly treeless savannah.

Cucurbitaceæ: the half-wild Gurji, Cucumis Melo, var. agrestis, is common, and the Bambus, a variety of water-melon, is known in the North.

Rubiaceæ: a characteristic species is Randia Nilotica, a thorny shrub; Gardenia Sokotensis is a new species found on low rocky hills.

Apocynaceæ: the Kariya, Adenium Honghel, an unarmed cactus-like shrub, deciduous, with rose-coloured flowers, planted in towns, is characteristic.

Asclepiadaceæ: the small milk-weed, Glossonema Nubicum, and the twiners Oxystelma Bornuense, Pergularia tomentosa and Leptadenia lancifolia, are all abundant, while the Karan masallachi, Caralluma Dalzielii, generally planted farther south, is found wild on bare rocky places.

Euphorbiaceæ: very typical are the two milk hedge Euphorbias, Aguwa, E. sepium, and Fidda sartsi, E. lateriflora.

Moraceæ: species of Ficus planted for shade grow to a large size, especially the Chediya, F. Thonningii, and the Durumi, F. syringifolia; other species generally start as epiphytes.

The Gramineæ is the prevailing Natural Order of Monocotyledons, and includes all types—little annuals, perennial-rooted Andropogons, etc., and the Burugu, Panicum stagninum, which blocks the streams. The fragrant Nobe, Cymbopogon Sennariensis, is a characteristic tufted species, whilst the bur-grass Karangia, Cenchrus catharticus, has long since spread far southward.

Rice and wheat are cultivated; the Bulrush Millet, Gero, Pennisetum typhoideum, tends to displace Sorghum, and a wild rice, Oryza silvestris, is found. The cultivated sugar-cane is the Takanda, Sorghum vulgare, var. saccharatum.

Of Liliaceæ the onion and garlic are features of cultivation. Several bulbous herbs not peculiar to the North are common, e.g. Dipcadi occidentale, Urginea spp., etc.

The Goriba or Dum Palm, Hyphæne Thebaica, is predominant, accompanied also by the Giginya or Deleb Palm, while the Date begins to appear.

Within the limits of the Soudan Zone of vegetation many different types of savannah may be found, besides the expected alterations in botanical groupings resulting from the presence of perennial moisture or due to elevation and rocky outcrop. Leaving the latter out of account, a few notes may be made of some of the varieties familiar to travellers in the Northern Provinces.

1. Tree Savannah or Savannah Forest.

Across a considerable area of Central Hausaland, e.g. occupying a large part of the Zaria plateau west of the Bauchi Highlands, the country, where not cleared for farming, is covered with an open deciduous forest of fair height. This is a fairly closely wooded type, and although it contains few truly evergreen elements apart from those lining the streams, there is, perhaps owing to differing vegetative periods for different species and to the double flowering season noted for many trees in West Africa, practically always a fair amount of foliage present. A proportion of the trees have well developed stems and fairly high crowns, with a leafy canopy which filters but never excludes direct sunlight, and the average height of the larger trees is from 30 to 40 feet. In the best developed portions of such forest the grasses do not predominate, but frequent clearings or patches of stony outcrop lead to the open conditions in which hardy perennial grasses take root, and annual burning results in the encroachment and multiplication of areas of the lower bush savannah referred to below.

This variety of forest is typically seen in Zaria province, e.g. between the village of Ruka and the Koriga stream, near which point a sudden drop in elevation occurs, and is familiar in parts of South Sokoto, Kontagora and Nassarawa, etc. Lophira alata has its chief habitat here, but perhaps the prevailing and most characteristic tree is one called Doka, which has been identified as Isoberlinia doka, Craib, et Stapf. It has broad, shining leaves, and large, flat 5-6 seeded pods which dehisce with curling valves. It seeds abundantly, and young seedlings spring up quickly in the forest or by wayside clearings, etc. Along with it will be found its congener, the Fara doka, Isoberlinia Dalzielii, Craib, et Stapf., less abundant, and differing as to its more obvious features in having leaves not shining, a paler grey bark and a general slight degree of pubescence of all parts. Both species exude a coarse red resin, which does not appear to be of value.

Most of the arborescent species mentioned in the list of the average association detailed above are to be found, sometimes harbouring epiphytic Ansellias and a few woody climbers but no typical lianes, and an undergrowth composed of Leguminous and Composite herbs and undershrubs with some grasses. This type of forest probably at one time covered a much wider area and had a greater extension northward than at present. As mentioned above, a large proportion of its constituents may again be found in the Duru forest between Sokoto and Kano, while within the memory of officials of the present administration areas of woodland previously visible from Sokoto have been denuded for firewood. It tends progressively to give place to the following more open variety of savannah.

2. Bush Savannah.

This is probably the form of “bush” with which travelling officials, hunters, and others are most familiar in every province, and is, when not overloaded with tall grass, deserving of the term “open orchard savannah.” It is composed of scattered shrubs and small trees of short growth and of a considerable sameness, the whole picture being practically filled in with grasses, which may grow to a height of 6 to 8 feet in the rains, but which are swept off by bush-fires in the dry period, leaving bare the intervening spaces, soon to be reoccupied by suffrutescent plants with persistent rootstocks, and later by weeds and the same grasses as before. This resurrection is not due to seeding, which is itself abundant, but mainly to the fact that the majority of bush grasses have perennial underground stems, which, once given occupation, are difficult to dislodge, and, assisted by the recurrent fires, which kill off the seeds and the seedlings of broad-leaved trees, have everything in favour of their natural progress to predominance.

The commoner bush grasses of this habit found here are: Andropogon Gayanus, Cymbopogon Ruprechtii, C. diplandrus, C. giganteum, C. hirtus, C. rufus, Andropogon tectorum, A. apricus, Rottbœllia exaltata, Pennisetum pedicellatum, etc. In clumps, generally found in special situations, e.g. near river banks, etc., are Vetiveria zizanoides, Saccharum spontaneum, Arundo donax, etc. It is possible that some of these species which now cumber the soil might be put to use in supplying the raw material for paper.

The prevailing shrubs and small trees of this formation are generally somewhat as follows: Bauhinia reticulata and B. rufescens, Detarium Senegalense, several species of Combretum with the dwarf C. herbaceum; also Afrormosia laxiflora and occasional Acacias, e.g. A. Sieberiana, Entada Sudanica, Dichrostachys nutans; bright flowering species, such as Cochlospermum tinctorium; several shrubby species of Hibiscus; Cassia Arereh, C. Goratensis and other species, Lonchocarpus laxiflorus, Securidaca longipedunculata, Grewia mollis, Feretia canthioides; the Gardenias—G. ternifolia, G. erubescens, etc.; Stereospermum Kunthianum, Sarcocephalus Russegeri, Parinarium curatellæfolium, Psorospermum Senegalense, Ximenia Americana, Anona Senegalensis, Pseudocedrela Kotschyi, Strychnos spinosa and other spp., Bridelia ferruginea, Hymenocardia acida, Gymnosporia Senegalensis. Occasional larger trees will often be species of Terminalia, Prosopis oblonga, Butyrospermum Parkii, Lophira alata, Vitex Cienkowskii, Sterculia tomentosa, Pterocarpus erinaceus, or even Afzelia Africana and Paradaniellia Oliveri.

In the above association remark must be made of the Taura, Detarium Senegalense, which is here rarely of dimensions meriting the designation of tree, and therefore very different from the large timber known in the southern forests and found also on the forested slopes of Patti at Lokoja; of the Makarfo, a tree of twisted habit, not often over 30 feet high, with flaking bark, apparently much inferior to the Afrormosia laxiflora, if it is this species, in the greater mixed deciduous forests farther south; and of the Tsada, Ximenia Americana, which is here unarmed, has rather thin, glabrous leaves, sometimes almost shining, and thus differs in habit from the coastal variety, if the identity is certain, which is spiny, has dull leaves sometimes half-succulent, and is appropriately called by the French “Citron de la mer.”

3. Park Savannah.

The open park-like formation is another which is typical of this region. It is, perhaps, best seen where the population is not quite sparse, as in the latter case the previous type tends to take possession. The Shea Butter Tree is the one which more than any other gives the tone to this type, but Parkia filicoidea and, especially in the North, the Tamarind are perhaps equally representative. The two first-named, though not necessarily indicating the proximity of a village, have probably in most cases owners, and the intervening spaces may or may not be more or less cultivated. Open park-like country may, however, occur apart from any contemporary interference by man, and wide stretches of it appear alternating with scattered orchard bush or with open grass-land. The grasses are of the previously mentioned types, with many species of Eragrostis, Aristida, small annual tufted grasses and sedges, along with Cassia mimosoides, Oldenlandia grandiflora, O. Senegalensis and other Leguminous and Rubiaceous weeds. Other trees which well maintain the park-like appearance are Terminalia macroptera, occasional species of Ficus, Vitex Cienkowskii, Acacia Arabica and A. Sieberiana.

In flat, wide-stretching meadows which are often marshy in the rains, this formation also maintains its character, single trees or island-like clusters of tree and shrub dotting the expanse of heavy grass which is burnt to desolation by the yearly fires. These islets are generally found to be composed of Giyaiya, Mitragyne Africana, with shrubs such as Feretia canthioides, Sarcocephalus Russegeri, and scrambling undershrubs added thereto, while the edge of such a meadow or “fadama” is in some cases fringed with deciduous high woods, in which occasionally timbers like Khaya Senegalensis and Paradaniellia Oliveri may appear along with the vegetation characteristic of Type 1.

4. Evergreen Fringing Belts.

Along the water-courses which intersect the savannah lands will be found dark evergreen strips of foliage, which, when extending beyond the stream-banks and forming a fairly dense canopy, whatever the nature of the underwood, are generally implied in the Hausa word “kurumi.” The streams may not be always truly perennial, but the verdure remains because the moisture in the soil persists long enough to maintain the non-deciduous type, although bush-fires may reach their very margins. Where a perennial stream of any magnitude occurs, species will be found whose distribution in the Soudan Zone is confined to such localities, but which are widely represented in the South.

Instead of enumerating the constituents of these strips of fringing forest, we may briefly refer to the vegetation of the River Benué, which has been already indicated as in some degree marking the boundary between the semi-evergreen or mixed deciduous forests and the drier tree savannah and open bush lands. The evergreen galleries along the streams or fringing the swampy glades may be taken as on the whole botanically similar to the bank foliage of the Benué and its backwaters, creeks and tributaries. One feature of this type is the abundance of woody climbers, often concealing the foliage of their supports, and conspicuous to the eye in the flowering season are the Combretaceæ, which are here scrambling and climbing shrubs instead of erect trees, e.g. the flame-flowered Combretum racemosum, C. constrictum, etc., Quisqualis Indica and others; also two or three species of Landolphia with other rubber vines, and of Mussænda, scarlet-fruited Connaraceæ, Uncaria Africana, climbing by its old flower-stalks becoming woody hooks, and Alchornea cordata, the most typical liane of these formations. Other twiners are the showy moon-convolvulus, Calonyction speciosum (Ipomæa bona-nox), the Cowhage, Mucuna pruriensis, Dioclea reflexa, Entada scandens and numerous Ampelideæ. These tend to form a dense and sometimes impenetrable tangle, but where trees of timber size occur the undergrowth is more scanty and a variety of forest weeds appear, in which the Scitamineæ may be prominent.

The Benué region is rich in trees, of which the following species may be mentioned: Goron ruwa, Irvingia Smithii, and Gedar kurumi, Pterocarpus esculentus, Trichilia retusa, the large timber tree called Kiriyar kurumi (undetermined), Erythrophlœum Guineense, Millettia sp., Sanagana and M. sericeus, Cynometra Vogelii, Anthocleista nobilis, Berlinia Heudelotii, Baphia nitida, Chlorophora excelsa, Cola laurifolia, Parinarium subcordatum, Kigelia Æthiopica, Uapaca Guineensis (here a large tree and sometimes prop-rooted), Ficus spp. Smaller trees and shrubs are: Spathodea campanulata, Voacanga obtusa and V. Africana, Morinda citrifolia, Xylopia parviflora, Zanthoxylum Senegalense, Oncoba spinosa, Vangueria euonymoides, Ixora radiata, Polysphæria macrostyla, Garcinia ovalifolia, Myrianthus serratus, Elæis Guineensis and Raphia vinifera. Not all of these extend far beyond the Benué, but the majority of them will be found in one or other fringing belt far into the deciduous region, and perhaps the two which best represent this extension of the semi-evergreen to the savannah are the woody climber Alchornea cordata and the tree Irvingia Smithii.

In a general view, Northern Nigeria, thus lying beyond the equatorial belt, possesses plant features which, apart from river and stream fringes, range between the mixed deciduous and xerophilous habit, and in the dry season the prevailing character of the open savannah forests is a monotonous drab or grey, intersected by the dark lines of greenery following the streams or encircling the swamps. The climate is largely of the continental type, with a temperature ranging from 120° F. to 40° or less (exclusive of thermometer readings on the Bauchi plateau), and a rainfall which throughout will usually fall between 30 and 50 or 60 inches, with diminution to 20 or even 10 inches in the most northerly provinces. Such a climate, with the concomitant regularity of two, not four, well marked seasons, the dry and the wet, is entirely that associated with the occurrence of savannah formations, scattered bush with prevailing grasses, suffrutescent herbs and small trees, much open grass or thinly timbered park-land, with stretches of thick woods which are generally not heavily grassed and never cumbered with impenetrable undergrowth.

Trees which are valuable timber species in the moist southern forests often scarcely attain reputable dimensions in the deciduous zone.

These conditions also, which are doubtless partly the result of ill-considered human operations, put certain definite restrictions on cultivated species and determine the character of the natural products of the wild. The staple cereal is Dawa or Sorghum, instead of maize, with Gero or Pennisetum typhoideum in the North. Possibly the limit of Guinea Corn as a staple of native cultivation is also the limit of the savannah forests, i.e. of the region of trees of secondary size, short of the region of Acacias, of Geza, Combretum altum, and of scrub, where Bulrush Millet is the commoner. Both species are generally cultivated along with beans, Vigna Sinensis. The sweet potato displaces the yam and cassava; industrial cultivation is represented by cotton and indigo. Of forest products, the most representative are Shea nuts and gum arabic, rather than rubber and large timber; and lastly, both cattle-grazing and horse-breeding are important industries proper to the region.

VII. Some Trees of Hausaland.

By Dr. J. M. Dalziel.

A few notes on some of the better known trees of Northern Nigeria are here given, the Hausa name being appended in most cases.

Afrormosia laxiflora, Harms (Leguminosæ). Makarfo.

In the mixed deciduous forests towards the coast this appears as a large timber tree, in certain regions dominant both in abundance and size, and is also a constituent of the moist evergreen forests. In Northern Nigeria it never forms a straight stem, never attains the dimensions of a timber tree, and has generally a twisted stem and main branches. Its habit, therefore, rather than its mere presence, affords a striking instance of the changes accompanying the limited rainfall of the savannah forests, and its distribution probably does not extend beyond the northern boundary. The trunk has a somewhat pale piebald appearance, resulting from the flaking of large pieces of the bark exposing lighter portions below. The centre wood is so dark in colour as to have led European foremen of works to report it as lignum vitæ, and the wood is hard enough to earn for it in some districts, along with other trees, the designation “break axe.” It has shining leaves, whitish flowers and thin, flat pods.

Afzelia Africana, Sm. Kawo; “African” or “Rhodesian” Mahogany, “Mahogany Bean,” etc.

A large tree, common to nearly all types of forest in West Africa, tropical high forest, mixed deciduous and savannah. In Northern Nigeria large specimens may still be found, though these do not generally have tall, straight stems, but show the wide-spreading umbrella crown common in drier regions.

Paradaniellia Oliveri, Rolfe. Kadaura or Maje.

This has previously been classed with Daniellia thurifera, Bennett, the so-called West African Copaiba Balsam Tree.

In the Northern Provinces of Nigeria it is one of the largest trees, 50 to 80 feet, with strong, straight stems and affording good timber for local use. The chief native use of the oleo resin is to fumigate garments. Its distribution probably stops short of the northern boundary.

Isoberlinia doka, Craib, et Stapf. Doka.

A tree which is the prevailing type in the savannah forests of Central Hausaland, generally 30 to 40 feet high, with broad, shining leaves, rather small white flowers and large flat pods containing five or six discoid seeds. The valves of the pods curl up after dehiscence, and young seedlings spring up vigorously where not choked by grass, farm clearings in Zaria province being often quickly occupied by them.

A coarse red resin exudes from injuries or punctures of the bark.

Isoberlinia Dalzielii, Craib et Stapf. Fara doka.

Another new species of similar occurrence and habit, differing in having a more grey appearance associated with a slight pubescence, leaves not shining and pods less smooth. A species of the wild silkworm, Anaphe Moloneyi, and perhaps others, are found on them.

Pterocarpus erinaceus, Poir. Madobia; “Senegal Rosewood,” “African Kino,” etc.

A tree generally of 30 to 40 feet or more in open savannah forests, easily recognized by its bright yellow flowers, the regular venation of the leaves, and the bristly, flat, one-seeded pods. The blood-red resin is a variety of Kino, and in districts where the Camwood is not found, the bark of Madobia is sometimes sold as a substitute. The wood is hard and fine-grained.

Cassia Sieberiana, DC. and C.; Kotschyana, Oliv. Marga or Gamafada.

These are small trees with conspicuous yellow flower racemes, having a superficial resemblance to laburnum. They are abundant in the dry savannah regions as well as in savannah forest, and flower freely in the dry season. The pods are long and cylindrical and do not dehisce. Cassia Arereh, Del., is similar, but the leaves are more acuminated and the pods split up longitudinally.

Detarium Senegalense, Gmel. Taura.

A good timber tree in the mixed deciduous and higher savannah forests, as also in the mountainous peninsula of Sierra Leone. Fairly large specimens of timber dimensions occur in the rocky forest overlooking Lokoja, but the Hausa Taura, hitherto identified as botanically the same, is of a very different habit, abundantly represented in the open bush savannah as a shrub or small tree having somewhat flattened fruits, oval, less succulent than, and one-half or one-third the size of, those shed by the forest specimens.

Tamarindus Indica, Zinn. Tsamiya; “Tamarind Tree.”

A very familiar tree in the northern Hausa States and Bornu, as well as in French territory to the north, but much less common on parts of the border-line between Southern and Northern Nigeria, so that probably its actual distribution is local and interrupted. Barth places its limit at Tagalel, in Damerghu, or about 15° North latitude.

In Hausaland it is a conspicuous tree, less from its dimensions than from the beauty of its foliage, sometimes umbrella-spreading and at others compact, and giving a good deal of shade when in full leaf. The ground becomes littered with the small leaflets in the dry months, and as a rule little undergrowth is to be found beneath it.

In Sokoto and Kano provinces, and elsewhere in the North, specimens with a dense, compact and symmetrical crown are common, the branches often reaching to within 3 or 4 feet of the ground. The fruit has familiar medicinal and culinary uses, but rarely develops the soft rich pulp of the Indian specimens. One of the wild silkworms, Anaphe sp., feeds on the leaf, the silken nest being called “Tsamiyar Tsamiya.” A familiar association which did not escape the notice of Dr. Barth is that of tamarind and baobab, in which case the former is often without a proper bole and spreads itself half scandent amongst the stout branches of the baobab.

Parkia filicoidea, Welw. Dorowa; “West African Locust Bean.”

A characteristic tree of the savannah forests, and one of the most typical members of the open park-like formations. It appears to be scarce in Bornu, but abundant from Zaria to Katsina, and its northern limit is probably about 14° North latitude.

The pods afford both food and fodder, the fermented cakes called Daudawa, made from the seeds, being an article of local commerce. In the bush, far from villages, Dorowa trees are ownerless, but elsewhere they are generally private property.

Burkea Africana, Hook. Farin makarfo.

A tree of 30 to 40 feet, of irregular distribution in open savannah forests, fairly common between Yola and Bornu as well as in Southern Sokoto. It has light, silky foliage, flowers in pendulous, creamy spikes, and dark, almost black, bark. The hard wood is used for handles of axes and hoes.

Prosopis oblonga, Benth. Kiriya.

A common tree of the savannah region, extending beyond the Anglo-French boundary, but better developed in the Benué region, where fair timber specimens occur. The wood is hard, with red centre wood, and takes a beautiful polish. It is recognized by its acacia-like foliage, spikes of creamy flowers and stout brown pods, with seeds sometimes used like those of Dorowa.

Bauhinia reticulata, DC. Kargo.

A shrub or small tree, one of the commonest constituents of the bush savannahs; readily recognized by the cleft leaves, rusty bark and flat, twisted pods. The tough bark forms an emergency tie-tie, and its long vast fibres furnish strong cordage, which is its chief use in Northern Nigeria. The bark and leaves, containing tannin, have astringent uses.

Acacia Sieberiana, DC. Fara kaya, or “White Thorn Acacia.”

A very widely distributed species in the deciduous zone, not usually gregarious and occasionally flat-topped. It is easily recognized by its generally dark foliage and pale bark, the flowers not yellow, but in small, creamy-white balls, and by the long white thorns. It yields a soluble gum, which is perhaps not of the best quality.

Acacia Arabica, Willd. Bagaruwa; Indian “Babool.”

One of the commonest species, especially in the northern Hausa States and Bornu, and a source of gum arabic. The flowers are in bright yellow balls and the foliage is a good camel food. The jointed pods are “Sant” or “Gambia” pods, used all over the Soudan for tanning.

Acacia Senegalensis, Willd. Dakwora.

Usually only a shrub, not often over 10 feet, sometimes gregarious, and characteristic of the thin bush savannahs; it has grey bark, flowers in white spikes, and three sharp recurved stipular hooks at the base of each leaf.

This species yields probably the best gum from Senegal to Somali, and the root-bark affords a very tough fibre.

Acacia albida, Del., var. saccharata, Benth. Gawo.

A fair-sized tree, confined to the open dry country in the North, extending into French territory, and an important camel food, but not a gum yielder. The flowers are in creamy-white spikes and the pods are yellow and twisted. It is peculiarly deciduous in the wet season, and bursts into foliage just at the cessation of the rains.

Acacia Seyal, Del. Dussa; “Talh of the Soudan.”

A rather small tree, not often over 20 feet, but gregarious and very abundant in North-east Hausaland and Bornu, less common, but local, in Sokoto, etc. It has a yellow or ochrey bark, white thorns and brilliant yellow balls of flowers, and the pods are narrow, sickle-curved and constricted between the seeds. The gum is of good quality, but not equal to that of A. Senegal.

Acacia campylacantha, Hochst. “Farichin shafu” (= Falcon’s claw).

A fairly tall tree with white flower-spikes and strongly curved spines suggesting the native name. It is sometimes gregarious in limited forest patches, and the gum is said to be good in colour, cleanliness, etc.

Fig. 41.—A Baobab (Adansonia digitata).

Fig. 42.—Giginya or “Fan Palm” (Borassus flabellifer, var. Æthiopum), with Water-lilies (Nymphæaceæ).

To face p. 208.

Albizzia Chevalieri, G. et P. Katsari.

A tree of 30 to 40 feet, common in the more open savannah formations, especially in the northern districts. It has whitish flower-balls, with long, pinkish stamens and thin, flat pods. The bark is sometimes used for tanning.

Entada Sudanica, Schweinf. Tawatsa.

A small tree of the savannah forests and open plains, easily distinguished by the peculiar jointed pods, each embossed seed section falling out and leaving the empty marginal frame. The flowers are in yellowish axillary spikes, generally two or three together.

Mimosa asperata, Linn. Kaidaji.

Forms dense thorny thickets fringing the open bush streams. The flowers are in pinkish balls, and the leaves possess the sensitive quality in a mild degree.

Lophira alata, Banks (Ochnaceæ). Mijin kade.

An “African Oak” and one of the most familiar trees of the savannah forests and open country. It is apparently very similar to Lophira procera, the “Red Ironwood” timber tree of the southern forests; frequently stunted by forest fires. The seeds yield an oil and the bark is medicinal. The flowers are in handsome white panicles, appearing about November or December, and the leaf and habit often give it an appearance resembling the Shea Butter Tree, but the leaf is beautiful and finely veined. An extraordinary fact is the widespread belief of pagan tribes in the efficiency of the leaf as a charm.

Eriodendron orientale, Steud. (Malvaceæ). Rimi; “Silk-cotton Tree.”

A giant in the evergreen forests, and still a comparative giant in the dry zone. In Northern Hausa towns the only very tall trees are Rimi; the wood is light and the stems are sometimes hollowed out for canoes: the floss of the seeds is Kapok, and has the usual local uses. Barth says its distribution eastwards stops at 11° East longitude, and that it is therefore absent from Bornu proper.

Northwards it apparently scarcely extends beyond the Anglo-French boundary.

Bombax buonopozense, Beauv. Gurjiya; “Red-flowered Silk-cotton Tree.”

A member of the evergreen forests, but quite a common tree of the open country and savannah forests, sometimes more or less gregarious, and extending at least beyond the Anglo-French border. It reaches about 40 feet or more in height, with crowded spines on the bark and tulip-like red flowers appearing during the deciduous period, generally after the middle of December and in January.

Adansonia digitata, B. Juss. Kuka; “Baobab.”

A characteristic tree of the dry savannah regions, often grouped in inhabited areas, with enormously stout stems, but in height limited to 40 to 60 feet. Specimens of 30 to 40 feet girth are not quite uncommon, the swollen stem, with soft, spongy wood, being an adaptation to a dry climate, by storing water to meet excessive transpiration by the leaves.

The bark is smooth and often has a shiny purplish tinge. Apart from fibre from both bark and wood, the dry fruit pulp and the seeds are prepared in various ways as food and drink. Large specimens are still found at Maradi, north of the Sokoto boundary, but chiefly stunted trees are met with at Zinder.

Sterculia tomentosa, G. et P. (Sterculiaceæ). Kukuki.

A member of the semi-evergreen forests and common also in the dry zone as a medium-sized tree with soft, palmate-shaped leaves and pods four or five together, splitting to expose the black seeds with yellow arils. A watery juice from the bark refreshes thirsty travellers and a kind of gum tragacanth exudes from the trunk.

Hannoa undulata, Planch. (Simarubeæ). Namijin gwabsa or Takandar giwa. (One of two species called by the latter name, vide Cussonia.)

A common tree of no great size in the savannah forest. The leaves are pinnate, with five to seven leaflets on long stalks, the flowers, in creamy, fragrant panicles, appearing in October or November, and the fruit is a black plum with unpleasant taste.

Irvingia Smithii, Hook. fil.

A tree of evergreen and mixed deciduous forests which invades the ravines and fringing belts in the savannah region as far at least as Kontagora. In the Benué region it is a fairly large tree of 40 feet or more, often gregarious, as in a patch of moist forest opposite Katsina Allah, along with Pterocarpus esculentus. The scarlet fruits are known as Goron ruwa or Goron biri (i.e. Water or Monkey Kola), and are eaten by monkeys.

Balanites Ægyptiaca, Del. Aduwa; “Desert Date.”

Typical of the Soudan and of the northern drier provinces of Nigeria and extending into French territory; characterized by its bifoliate deciduous leaves, spiny habit in dry soil and evergreen bark. The yellow oval fruit has a thin layer of sugary, bitter-sweet pulp, and the kernel yields Betu oil.

Boswellia odorata, Hutch., and B. Dalzielii, Hutch. (Burseraceæ). Hano or Ararabi.

Two new species of “Frankincense Tree,” yielding a fragrant gum resin. They reach 30 feet or so in height, have white bark which peels off in thin sheets, racemes of white flowers and pinnate leaves with serrate leaflets.

Commiphora Kerstingii, Engl. Dali or Bazana.

A small tree, commonly used as a fence support around native compounds. The bark is smooth and green, and the soft wood can be hollowed out for quivers.

Balsamodendron Africanum, A. Rich. Dashi.

A shrub commoner in the northern regions, extending beyond the Anglo-French boundary. In arid regions it forms a good hedge, with some resemblance to the blackthorn. The leaves and bark are fragrant, and it yields a gum resin which is a variety of African myrrh.

Khaya Senegalensis, A. Juss. (Meliaceæ). Madachi; “West African Mahogany” of the dry zone.

A large tree for the dry savannah region, but one of the smaller of the mahoganies. In the North, where dry conditions prevail, it tends to favour the banks of streams or the edges of marshy meadows, and is never buttressed, but often acquires a good spreading crown. Good timber specimens have been found on the Gurara River, but apart from this, and perhaps some other favoured localities, it does not as a rule exceed about 4 feet to 4½ feet in girth. It occurs from Gambia to Nigeria and Kamerun, and is again found as a West African element in the flora of Uganda and Mozambique. Northwards it reaches North Sokoto, but apparently does not extend to Zinder. The bark is a reputed bitter tonic in native medicine.

Pseudocedrela Kotschyi, Harms. Toman or Tonas; “Dry-zone Cedar.”

In Northern Nigeria this is rarely more than a small to medium-sized tree of 20 to 30 feet, and not usually of good straight growth, probably from the effect of annual fires, but yielding a fine wood. The leaflets are undulate-margined, the flowers are in graceful panicles, appearing about February and March, and the dry, erect capsules, full of winged seeds, split from above downwards in five valves. Occasionally little copses of the species occur, as it seeds freely and numerous seedlings arise—most of them, however, doomed to perish in the next bush-fire. In protected localities it might be fostered into a useful timber tree. Natives find various medicinal uses for the bark.

Trichilia emetica, Vahl. Jan sayi.

A fairly common tree across Central Hausaland, not often much over 20 feet in height. It has medicinal properties; the white flowers are fragrant and used to rub the teeth, and the seeds yield a less important oil.

Trichilia retusa, Oliv.

A large timber tree with tall, straight stems, found in the Benué region. The flowers are white, appearing about January, in axillary racemes or below the leaves; the leaflets are generally five or three, with wide, shallow indentation at the tip.

Odina Barteri (Anacardiaceæ). Faru.

A fair-sized deciduous tree of the savannah forests, with pinnate pubescent leaves and inconspicuous flowers in pendulous, clustered racemes. It yields a sort of resin, and the small fruits, tipped with four sharp points, are eaten by birds.

? Spondias sp. Danya.

A very common tree of the drier savannah forests, very abundant in the North; it has light foliage of pinnate leaves with small leaflets and a yellow, very pleasantly flavoured fruit, with a tough rind like that of the mango. The fruits litter the ground in the months of May and June. The wood is very hard and used for making a heavy kind of basin known as akushi.

Anogeissus leiocarpus, G. et P. (Combretaceæ). Marike.

This is one of the “Chew-sticks” of Yoruba, and while occurring in fringing forests and evergreen patches, it is very common in the open savannah regions, but probably does not extend beyond the northern boundary. It may be 50 feet in height, and possesses light, graceful foliage, pale bark and small yellowish flowers in globose heads, forming tiny dry two-winged fruits. It affords an inferior gum and is much used medicinally.

Terminalia sp., near T. macroptera, G. et P. Baushe.

A fairly large tree, 40 feet or more in height, with the oval winged and embossed fruits of the genus, along with its congeners, e.g. T. Elliotii, Engl. and Diels, T. Baumanii, Engl. and Diels, etc., very abundant and typical of the savannahs of Northern Nigeria. Bows and sticks are made from the roots.

Terminalia macroptera, G. et P. Kandari.

A smaller tree with much broader leaves, typical of open park-like formations.

Combretum spp.

Several arborescent species of Combretum are truly characteristic of the open and bush savannahs, and are well represented even in the northern parts, where, however, in some districts, they are replaced by Acacias. They are practically all gum-bearing; the flowers are small and yellowish in axillary spikes, but the genus is generally easily recognized by the fruits having four papery wings and the usually whorled arrangement of the leaves. The Northern Nigerian species have not all been fully determined, and the native names are at present somewhat confused and may include more than one species. Most of them in this region are shrubs or small trees, occasionally reaching 30 feet or so, with smooth or hoary foliage. The Taramniya is generally C. leonense, Engl. and Diels; the Chiriri of Sogoto includes probably C. Hartmannianum, Schweinf., and other species; the Dalo is C. glutinosum, Perr., or near it.

Parinarium curatellæfolium, Planch (Rosaceæ). Rura.

A small tree, very common in the bush and forest savannah, usually only about 10 to 15 feet high, with pale leaves and a dry, pear-like fruit. Of its congeners, P. macrophyllum, Sabine, the Gawasa or Gingerbread Plum, is its representative in most northerly provinces, and P. polyandrum, Benth., with grape-like bunches of purple not edible fruit, is common in the southern parts of the deciduous region.

Eugenia Owariensis, Beauv. (Myrtaceæ). Malmo.

A small tree, generally about 20 to 30 feet in height and always found in moist places, by streams, etc. It has shining, odorous foliage, white, fragrant flower-clusters, and a small black-purple, succulent fruit.

Cussonia Nigerica, Hutch. (Araliaceæ). Gwabsa or Takandar giwa.

A new species, occurring in the open and bush savannahs as a small tree from 10 to 15 feet in height, with peculiar bare, raking branches, producing at their ends clusters of digitate leaves or of long catkin-like spikes of inconspicuous flowers. Incisions in the rough, fissured bark yield a clear gum. (For the native name compare Hannoa undulata.)

Cratæva Adansonii, G. et P. (Capparideæ). Ingidido.

A small tree, occasionally 20 feet high, fairly abundant in the North, of local distribution and common in towns. The leaves are trifoliate and can be used as a vegetable; the flowers are white and the fruit yellow, spherical, and about the size of a small orange.

Zizyphus spina-Christi, Willd. (Rhamnaceæ). Kurna.

A small tree characteristic of the dry open regions and commonly planted in northern towns. It is generally about 10 to 20 feet high, spiny, with leaves three-nerved, and a rather dry, edible berry of pleasant taste.

Z. jujuba, Lam., is the Magariya, and is similar, but in these regions generally has less of a stem and is more shrubby and thorny, and is not, as a rule, planted, though the fruit is even pleasanter.

Sarcocephalus Russegeri (Rubiaceæ). Tafashia.

A shrub, or occasionally a small tree, common in moist meadows, but found also in the open dry bush. The flowers are in rather large creamy balls, and the coarse red, succulent fruit is the analogue of the Sierra Leone peach, S. esculentus, Afzel, which grows to a large tree in the evergreen forests.

Mitragyne Africana, Korth. Giyaiya.

This is a characteristic tree of swampy areas in the deciduous regions, found by streams and marshes or forming island-clumps with a few lesser shrubs and weeds in the grassy meadows, which dry up in the rainless months. It is generally from 20 to 30 feet in height and has close, spherical heads of whitish flowers and smooth, but not shining, leaves with regular venation.

Crossopteryx Kotschyana, Fenzl. Kasfiya.

A small tree of 15 to 20 feet, with foliage resembling that of Giyaiya, bunches of whitish flowers, and abundant small black, pill-like fruits, which remain attached long after they are ripe.

Adina microcephala, Hiern. Kadanyar rafi.

A fairly tall tree of 30 to 40 feet, found in stream-banks in the savannah region. It has whitish balls of flowers and tapering smooth leaves.

Morelia Senegalensis, A. Rich. Innuwar bauna.

An evergreen shrub 10 to 20 feet high, common on stream-banks, and found both in the semi-evergreen forests and in the fringing belts of the deciduous region. The flowers are white and somewhat fragrant, and the fruit is spherical, tipped by the tubular remains of the calyx.

Butyrospermum Parkii, Kotschii. (Sapotaceæ). Kadanya; “Shea Butter Tree.”

A typical tree of the savannah hinterlands, and one which gives the park-like character to many parts of Northern Nigeria, it barely extends to the northern boundary, and is rarer on the Bornu side. It is generally 25 to 30 feet high or more, with a dense crown and a curiously corrugated bark. Flowers, in white, head-like clusters generally appear about December. The brown, chestnut-like kernels are ripe about July. The milky juice and the coarser venation of the leaves readily distinguish this tree from Lophira alata.

Diospyros mespiliformis, Hochst. (Ebenaceæ). Kanya or Kaiwa; “African Ebony.”

A fairly large tree, up to about 40 feet in height, in the savannah forests and open country, extending north to beyond the Anglo-French boundary, larger in the mixed deciduous forests farther south and in fringing evergreen belts. The foliage is dark and the bark blackish; the inconspicuous whitish flowers, of separate sexes on different trees, are attractive to bees. The wood is white, with a black heartwood, and the spherical yellow fruits (“Monkey Guava”) have a crisp rind and sweet edible pulp, with four or five seeds.

Strychnos spinosa, Lam. (Loganiaceæ). Kokiya.

A small thorny tree with opposite three- to five-nerved leaves, conspicuous by its round yellow fruit, which is orange-like, but has a hard rind and flat seeds embedded in a pleasant acid edible pulp.

Cordia Abyssinica, R. Br. (Boragineæ). Aliliba.

A shrub or small tree with broad leaves and white flowers, valued for the sweet yellow berries, which are used in making sweetmeats.

Kigelia Æthiopica, Decne.; var. Bornuensis, Sprague (Bignoniaceæ). Rahaina or Rawuya.

A species of “Sausage Tree,” of irregular distribution in Northern Nigeria, known in Sokoto, etc., but commoner in the Benué region and in Bornu (possibly more than one species occurring). It grows to a fairly large size, with dense foliage and pendulous racemes of lurid purple and spotted flowers and large, yam-like fruits.

Stereospermum Kunthianum, Cham. Jiri or Sansami.

A small tree of the savannah forests, with smooth pale bark, beautiful pink caducous blossoms and long slender pods.

Vitex Cienkowskii, Kotschii et Peyr. (Verbenaceæ). Dinya.

A fairly large tree, chiefly of open forest country and extending at least as far as the Anglo-French border. The bark is somewhat smooth, the crown of digitate leaves fairly dense, and the black, damson-like fruits are used in making molasses and sweetmeats. The natives value the wood as strong and suitable for local use.

Uapaca Guineensis, Muell. Arg. (Euphorbiaceæ). Ka Jafogo.

In the open country a rather small tree, with the habit of a Ficus, but becoming a large tree, sometimes prop-rooted, in the Benué region and in some ravines.

Chlorophora excelsa, Benth. and Hook. (Moraceæ). The “Iroko” or “Odum.”

Some of the splendid Nupé canoes are made of this, but the tree really belongs to the southern forests, though it occurs in the Benué region and perhaps in some northward extensions in river valleys.

Celtis integrifolia, Lam. Zuwo or Dukki.

This is a fairly large tree of the savannah forest region, found as far north at least as Sokoto. The leaves are edible and are used as fodder.

Ficus or Urostigma spp.

This genus has not yet been fully elaborated, and the native names cannot in all cases be definitely applied to distinct botanical species. The following appear tp be fairly established: Chediya, Ficus Thonningii, Bl., one of the commonest shade trees, planted in towns and abundant far North in French territory; Durumi, F. syringifolia, Warb., perhaps equally common, with shining heart-shaped and pointed leaves; Baure, F. gnaphalocarpa, A. Rich. (the rough-leaved species with soft figs which are sometimes considered edible); Uwar yara, F. Capensis, Thunb. (sensu lato), recognized by the wavy or indented-margined leaves, and especially by the figs being borne in dense clusters on the trunk; Gamji, F. platyphylla, Del. (the source of “Red Kano Rubber” and the host of one of the wild silkworms, Anaphe sp.). Kawuri probably includes F. kawuri, Hutch., and F. glumosa, Del. Wa is a species with broadly cordate leaves, strongly veined, and Shirinya is a narrow-leaved species. F. Vogelii, Mig., is a glossy-leaved rubber-tree, more abundant in ravines and in the moister forests farther South.

The Gamji and Shirinya, and perhaps some of the others, almost invariably begin life as epiphytes.

Most of the species have abundant aerial rootlets, and the latex of F. Vogelii, of Gamji, and perhaps of Kawuri and Shirinya, yields rubber of varying quality.

Raphia vinifera, P. Beauv. (Palmeæ). Tukuruwa; “Bamboo Palm,” “Wine Palm.”

This well-known palm is found in ravines in the savannah region as far as Zaria province, but is a proper member of swampy patches and moist forests of the South. Roofing poles and palm-wine are its products most used in the North.

Borassus flabellifer, var. Æthiopum, Warb. Giginya; “Deleb,” “Palmyra” or “Fan Palm.”

The most characteristic palm of Hausaland, with tall, straight and often beaded stems. The germinating shoots from the planted nuts are a vegetable called muruchi, and the wood and leaves have the familiar uses in house-building, mat and basket weaving, etc.

Hyphæne Thebaica, Mart. Goriba; “Dum” or “Gingerbread Palm.”

The typical palm of the more northerly Hausa provinces, characterized by its forked stems and obliquely fan-shaped leaves. The kernel and the rind of the nut are used in certain food preparations, and the fronds have the usual applications for plaited utensils, etc.

Phœnix dactylifera, Linn. Dabino; “Date Palm.”

Introduced by Arabs and confined (with a few exceptions, e.g. at Yola Mosque) to the Northern towns.

In Kano it may be possible to see the three palms, Deleb, Dum and Date, together, but the last is in no sense a tree of Hausaland.

CHAPTER IX

THE NIGERIAN TIMBER TREES

INDIGENOUS TREES OF NIGERIA

B. Southern Provinces.

Palmæ.

Raphia Hookeriana. Hooker’s Palm or the Piassava Palm. Aiko (Yoruba); Iya (Efik); Angor (Benin); Ori (Oban, Ekoi).

It is found chiefly in the Calabar, Warri, and Ondo provinces of Nigeria, mixed with R. vinifera at the edges of estuaries and rivers in the evergreen forest zone.

One of the main differences between this palm and R. vinifera is that the fruit is much shorter (at the most 1½ inches long and ¾ inch in diameter) and more stumpy in shape, coming abruptly to a point at the tip. R. vinifera, on the other hand, is much longer, reaching 2½ to 3 inches in length and ¾ inch to an inch in diameter, and it is very elliptical in shape. The bunches of fruit of this palm, R. Hookeriana, are much smaller, rarely exceeding more than a foot in length, and containing 50 to 75 nuts, whereas R. vinifera may have bunches 3 feet long, each containing 500 nuts or more. In the stem, too, this palm is smaller, often not reaching more than 6 to 9 inches in diameter, with a total height of 20 feet, whereas R. vinifera will reach over a foot in diameter and a total height of over 60 feet. The natural cleaning of the stem begins much later in this palm, and does not reach anything like the height of that of R. vinifera. In many specimens, in fact, the stem remains always more or less covered with the very upward tending branches. In this respect it reminds one a little of R. Ruffia. The leaves, however, are more similar to R. vinifera, but only about half the size, especially in length; they are not quite so wide, nor are the leaf stalks quite so large.

The timber is very similar, but more fibrous and of a looser texture than that of R. vinifera. It is a little easier to cut. In the older specimens the foliage still retains its dark green colour compared with the dry, yellowish hue which R. vinifera takes on as it gets older. It is a somewhat slow-growing, shade-bearing tree. It likes a somewhat rich soil, but can, however, stand in water, and apparently withstands floods. Natural regeneration appears to be good.

The timber has not been cut for export nor for local use. The fronds are occasionally used for a similar purpose as that of R. vinifera, and sometimes the leaves also.

Native Use.—The fronds and leaves are used in a similar way to those of R. vinifera. The base of the leaf stalk is cut off into lengths up to 6 feet (it almost encircles the tree and extends much further up than in the case of R. vinifera) and laid in stagnant water. After the intervening substance between the fibres has got more or less soft and partly rotted away, the whole is taken out and the fibres cleaned with a kind of comb. These are then dried, and packed together in bundles of 20 pounds upwards, and sold to the European factory as Piassava. This industry is more widespread in the Eket district of the Calabar province, but it has taken a great number of years of thought and careful attention to bring it up to its present dimensions. The cutting of the leaves is undertaken mostly by the men and the rotting and cleaning of the fibre mostly by the women. Before the war Piassava fibre was rarely worth more than £28 per ton. It is now worth over £70. Unless, however, a price of at least £20 per ton is offered in Liverpool market for this fibre, it is doubtful if the industry can be made profitable for everyone concerned, producers included.

Raphia vinifera. The Palm Wine Tree, or Tombo Palm, or Bamboo, the last named being the name used by the English-speaking Jekris. Ako (Yoruba); Emmaha Augor (Benin); Oukot (Efik).

It is found in the Abeokuta, Ondo, Benin, Warri, Owerri and Calabar provinces and the Colony of Nigeria, at the edges of the streams and rivers in the evergreen forest zone, where it grows in large groups and pure forests.

It is a medium-sized palm, growing separately with one stem, which clears itself of the leaf fronds for about half its height between the twelfth and fifteenth year. The trunk then is comparatively smooth, except for the very large scars of the leaf stalk. The fronds are the longest of any of the African palms, reaching sometimes a length of 40 feet, roughly sickle shaped; in section they reach about 2 inches diameter at the broadest part, and are a yellow-brown colour. The leaves come out from the stalk almost at a right angle, thus making them much wider and, owing to their greater length, much finer and heavier foliage than that of the Oil Palm, or even the Coconut Palm. In fact, an isolated specimen growing well could be not unfavourably compared to the Royal Palm in the grandeur of its spread of leaf and the beauty of the outward-spreading, fan-shaped bold crown. Both the male and the female flowers are very conspicuous. The bunches of fruit, up to 3 feet in length, hang down like enormous elongated bunches of yellow grapes. The nuts are covered with a smooth yellow hard skin, set in scales very similar to those of a cone, except that each scale is tightly joined to the next. When the fruit decays, or is boiled, the scales come off as well as the yellow, fibrous matter, which gives a yellowish tinge to the water. The main difference between the base of the Oil Palm and that of the leaf of this tree is the extension of it more than half round the bole in the case of R. vinifera, and also flatly and smoothly down the stem. On the other hand, in the Oil Palm the leaf grows more abruptly out of and away from the stem. Owing to the Tombo Palm stem being smaller (on the average only 9 inches in diameter), the base of the frond extends nearly all round the tree, the lower one overlapping the higher one, and each placed in revolving fashion round the trunk, one above the other. The leaf scars of the Oil Palm are much smaller. Owing to the greater length of the leaf of this palm, the crown does not appear to be such a tuft of leaves at the top of the tree as in the case of the Oil Palm. In old age it appears more as a cylindrical mass of leaves occupying the upper half or third of the tree.

The timber is more fibrous and soft than that of the Oil Palm. The fibres, however, are dark brown, almost black when very wet or after they have lain in water for any length of time.

On the whole the tree is slow-growing, even slower than the Oil Palm. It stands a good deal of shade in the earlier stages, but later on is apparently a light-demanding tree. It grows in freshwater swamps and at the edges of such places. Although it thrives best in certain localities, it can be planted and does grow on solid and comparatively dry land near Calabar. In the Calabar province they are often planted as an avenue leading up from the main road through the farm to the house. It will stand floods. Natural regeneration is good, and with the spread of propagation it tends to be more widely distributed. In the Calabar and Ogoja provinces seeds were distributed to the natives for planting for the production of palm wine to take the place of that obtained from the Oil Palm. The timber has not been used for export, nor has it been cut for local use. The leaf stalks, however, have been used for building labourers’ lines and in some European houses. In a similar way the leaves themselves have been used as a roofing material after being made up into small mats.

Native Use.—The tree is tapped near the base of the leading leaves, or at the base of the male inflorescence, for the production of the sap, which is collected in calabashes. These are placed in position every evening and emptied every morning, and replaced in position. Occasionally the chimpanzees climb up the palms, drink the wine in the calabash and replace it. A native once shot a chimpanzee, finding it was the thief of his palm wine and not a human being. The wine is of a white, sometimes almost creamy colour, and when fresh is quite thin and foamy. It has a rather pleasant, sweet, and almost sharp taste. After being kept a few days it begins to ferment, and even moderate quantities are intoxicating. Either fresh or fermented, it is sold in bottles or calabashes in the local markets. The supply scarcely, if ever, exceeds the demand. The natives often put pieces of the bark of Tala, Saccoglottis Gabunensis, in the wine to give it a more bitter taste. Occasionally also the bark of mahogany and other trees is used. Tala, however, is the correct bark to use, and it forms an article of local commerce for this purpose. Owing to the comparative inaccessibility of some of the “stands” of this tree away in the swampy regions near the estuaries of some of the larger rivers, such as the Benin and the Siluko, there are still vast areas where neither the leaves are cut nor the palms tapped for wine. The seeds are boiled and placed in the bottom of a canoe, and when sufficient canoes have been got together, each with its quota of boiled nuts, these are trodden with the feet of those in the canoe, and both the nuts and the scaly shell as well as the small amount of yellow flesh are thrown in the water of a half-stagnant river. This yellow substance partly blinds and stupefies the fish, the smaller ones of which come half floating and swimming to the surface, the larger ones being washed along near the bed of the river. These are caught in convenient places where the river has been staked all across its width and bamboo netting put down, except for an opening where a flexible net is used. Some of the people go about in small canoes, netting the fish that come to the surface. One of the most famous spots to see this is in the Osse River, in the reach just below Noami, where the combined fishery forces of the Jekris and, to a lesser extent, Sobos and Ijors, for a day or two in succession in April each year, carry on this work. The catch of fish obtained is enormous. Unless, however, it can be soon smoked and dried, much of it goes bad. This method of getting fish is also used by individual natives in stagnant backwaters of rivers and in isolated pools. The poison apparently does not spoil the taste or other quality of the fish. Occasionally this palm is also used for getting out the Piassava fibre, but it appears to be more difficult, and it is doubtful if it is as valuable as the fibre obtained from R. Hookeriana. Owing, however, to the fact that both species grow in the same locality and often quite mixed together, it is highly probable that part of the Piassava obtained is taken from this palm. In order to stimulate the flow of sap, a fire is often made at the base of the tree, which burns all the lower leaves and even part of the top, and thus induces an extra flow of sap, but of course to the detriment of a continual yield, as the tree subsequently dies.

In many parts of the country there is a regular local industry in the making of roofing mats from the leaves of this palm. The small ones, about 3 feet long, are, however, sold 25 for 3d. and the big ones, over 6 feet long, 25 for 6d. In some places they are cheaper. As a roofing material they are very durable, and will last at least seven years. If, however, they are put on very thickly, overlapping more than two-thirds of their width, and the roof is thoroughly smoked from the inside, it becomes nearly black, and will last fifteen years. For native houses it is one of the most used roofing materials, except in the Benin country, where the large Ewayon leaves are used. Roofing mats are, of course, being superseded by galvanized iron in the more civilized places. The leaf stalk is used both as a pole for pushing lighters or heavily laden canoes through comparatively shallow water, or as a boat-hook, or pushing and guiding pole for the smaller canoes in getting up swift, winding and comparatively narrow rivers.

Raphia Ruffia. Roofing Palm.

Chief Characteristics.—It does not form a proper stem, like other raphias; the long, thin leaves sprout out from the ground, and only when the tree is some years old is there any trace of a stem, which is quite short. The petioles are thin, compared to the length, and the leaflets are thin and narrow.

Distribution.—It is found in the Calabar and Ogoja Provinces of Nigeria. It is often planted near watercourses in damp valleys to provide roofing material for the natives, who make mats from the leaves (Ikom, Obubra districts).

Phœnix reclinata. Swamp Date Palm. Elekikobi (Yoruba); Ukukon (Benin).

A common tree of the Warri province of Nigeria. It is usually found in or at the edge of the mangrove swamp, where it appears to thrive. It is often rather bent in shape, and does not exceed 10 feet in height. It is usually partially gregarious, though the groups of this species are much smaller than those of P. spinosa. The natives in this locality scarcely use it at all. The fruit is rather smaller, and it bears in a less prolific manner than P. spinosa.

Phœnix spinosa. Wild Date Palm. Okun (Yoruba); Ukukon (Benin).

It is a common tree in the Ogoja, Benin, Ondo and Ibadan provinces of Nigeria. In appearance more like a very thin stemmed Oil Palm, on nearer approach the bluish-green, almost silvery, more open, shorter and rather sharply pointed fronds readily distinguish it from the Oil Palm group. The fruit is the shape of a very small date, many of which are borne on thin fibrous twigs of a very stout stalk. It is usually found in the open deciduous or savannah forest zone.

The natives use the stems for rafters and house-posts; the fruit and bark are used medicinally; and the leaves are used for making sieves, hats, mats and bags.

Calamus deerratus. Benin Cane or Rattan. Erogbo (Benin).

It is found in the Benin province of Nigeria. It is one of the rarer canes of the forest, has a yellow flower, and is found near Okenuhen. The canes are used for fences and house-building.

Eremospatha macrocarpa (Mann and Wenal). Small Benin Rattan. Ukan (Yoruba); Ikan (Benin).

It is found in the Benin, Calabar, Ondo and Abeokuta provinces of Nigeria.

It is a common ½-inch thick cane, which attains a length of nearly 200 feet. It grows in clumps and climbs up over the surrounding trees. The fruit is yellow and rather like a small larch cone which has not opened. It is used for making rope and baskets, tying timber rafts, house-building, etc.; in fact, it is the best cane in West Africa.

Eremospatha sp. Large Benin Rattan. Okakan (Benin).

It is found in Ondo, Abeokuta, Benin, Warri, Brass, Owerri, Calabar and Ogoja provinces of Nigeria.

It is a large creeper, nearly an inch in diameter and attaining a length of nearly 200 feet. It is usually found partly growing on other trees in more or less open places at the edge of the forest, near river banks, in the evergreen forest zone; it is also found at the edges of swamps in the same region. It often forms dense cane brakes. One of the most typical features of this cane is the reddish-orange cone-like fruit, which is borne in large clusters on the terminal shoot of the creeper.

The light-yellow, long spikes of the male flowers are most conspicuous early in the season, especially when seen from a canoe when passing down a river like the Osse.

The natives strip off the bark and long shoots of fish-hooklike spines, and use the comparatively smooth canes as supports for the canoe mats and for making tying material for house-building; it is also used for making rope. When whole, it is used in making bridges as well as for joining logs together for rafting purposes. When cut into short lengths and bent at one end, it can be used for walking-sticks.

It is rather a slow-growing creeper, and usually ten or twelve grow out of one root stock. In 1904 this cane was examined in England as a substitute for rattan, but it was found to be more brittle, and the internodes were found to be too close together to be attractive as walking-sticks. Still later, in 1908, it was tried for basket work, but was found to be too coarse both in structure and texture of grain.

Elæis Guineensis. The Oil Palm, the West African Palm. Ope, Ipa ukoro (Yoruba); Udin (Benin).

It is found in all the Southern Provinces of Nigeria and as far North as Zungeru, in the Northern Provinces. It belongs to the evergreen forest zone, though it will spread with cultivation into the mixed deciduous and dry zones.

It is the common palm of all the farms and forests of the moist and mixed zone of Nigeria. It bears a bunch of fruit containing as many as two thousand individual fruits in one drupe. In the drier parts there may be only as many as one hundred seeds. There is one forked palm on the right-hand side of the line about seven miles from Ibadan, just beyond Moor Plantation. This is a very rare occurrence, and I have only seen one in twelve years’ travelling in Nigeria. The male inflorescence is not unlike a very close horse’s tail, turned up on end. The orange-brown-coloured female flowers are very small, and do not last long (a few days). The male flowers always appear first, and above the female in each case. The natives say some trees only bear male flowers, but it is doubtful if this is ever true, except in very isolated cases. It bears fruit in the fifth year, and will go on for about a hundred years. There is a most marked difference in the height of a tree which has grown up in the “high forest” and one which has come up in an old farm, the former being fully 100 or even 150 feet high and the latter only 20 to 30 feet in height. In a similar way the bole of the forest-grown palm is only about 3 feet in girth, whereas the farm-grown palm may be over 6 feet in girth. It goes without saying that the latter bears larger bunches of fruit and the individual nuts are larger and also more numerous.

Between the twelfth and fifteenth year the tree begins to clear itself of the lower leaves, thus forming a clean bole up to the tuft of fronds at the top.

Owing to the fact that the bunches of fruit form in the axis of the leaf stalk, they are compressed very tightly, and thus ripen comparatively slowly. By cutting off the leaf immediately below the fruit, the ripening period is shortened by three weeks. This is, of course, partly due to the increased amount of light. Cutting leaves, however, above the fruit, or at all excessively in number, leads to a deceleration in growth, so that pruning should only be moderate. Both in the forest and in the open, epiphytic ferns, figs, and other plants grow amongst the leaves on the stem, and more especially later at the top of the tree. The trees are rarely, if ever, cleaned of these hindrances to healthy growth, but naturally they retard the flowering and ripening of the fruit. The leaves are also used for making brushes for sweeping the ground.

Native Use.—Oil is made from the pericarp of the fruit, and from the kernels, for rubbing on the skin. The leaf stalk is used for roof-poles.

Natural regeneration is good, although the Oil Palm thrives best in a deep, moist soil with considerable mineral content. It is, however, found growing amongst rocks on laterite and poor sandy land, and that in such case the rainfall is deficient, i.e. below 40 inches. A few small plantations have been made. It is noticeable that self-grown seedlings grow much slower than those transplanted. In the first year the self-sown seedlings grow only one pair of leaves, whereas those transplanted grow five or six in the same period. Apparently the Oil Palm does not thrive unless the soil is kept well covered and a good surface tilth maintained. With a planting distance of 20 to 24 feet there is considerable scope for the planting of other crops between. The chief difficulty appears to be to grow these at a profit without impoverishing the soil or hindering the quick development of the Oil Palm. On suitable soil the most profitable crops appear to be the following: ground-nuts, beans (three or four kinds), Egusi Bara, Citrullus vulgaris.

A fuller consideration of this subject, and the Oil Palm generally, will be found in the separate section about it.

Elæis Guineensis, var. Thompsonii. The Palm of Everlasting Life or King Palm. Eviromilla (Benin). This is the meaning according to the Benin name.

It is found in the Colony of Lagos, and Abeokuta and Benin provinces of Nigeria. On the whole, it is an uncommon tree, but there is no doubt of its being an indigenous tree to this part of Africa. The leaves are long and very compressed, being set at an acute angle to the leaf stalk and of smaller size than in any other species. It gives the palm almost the appearance of a Cycad. It also looks as if the leaves had closed up with the cold or were not fully developed. The leaves also are of a much darker green (almost olive-green) than the ordinary palm. Amongst the Benis it is considered the Sacred Oil Palm Tree, the nut obtained from it being especially revered. From the Resident’s office is seen one of these trees which was planted in the Benin City Arboretum some nine years ago. It is a very slow-growing palm, having scarcely one quarter of the rate of growth of the ordinary oil palm. The stem is much thinner in proportion to the height than the ordinary oil palm; and it does not attain more than half the height of an oil palm. When growing in a group, it gives quite a funereal appearance.

The nuts are used by the natives as “Ju-ju” of divination to see into the future. It is said that “the nuts talk,” in the Benin country, where the tree is held to be that of everlasting life.

Elæis sp. Ope trumfo (Yoruba).

Abeokuta province, Yoruba country.

Elæis sp. Small Oil Palm. Ope Ifu No. I (Yoruba); Ogiedi (Benin).

Abeokuta province, Yoruba country.

Elæis Guineensis, var. Lisombe. Palm, or Lisombe Palm, or Soft-shelled Palm. Ogeddin (Benin).

The main difference of this species is in the small oblong, pointed fruit on a much smaller drupe, and the larger quantity of oil obtained from the pericarp and the very small kernel in the nut. It is also much softer to crack. The foliage looks a fresher green than the ordinary variety; also the leaflets are placed at an acuter angle to the leaf stalk than the other.

It is not very prevalent in the Benin, Abeokuta, Calabar and Ogoja provinces of Nigeria.

Silviculture.—The nuts, when sown, do not germinate true to species, except for a few per cent. It is planted in the Indem country of the Ogoja province.

Native Use.—The oil is collected in a similar way to the other, but is liked more by the natives of Benin. The kernels are used for making oil as well.

Hyphæne. Dum Palm or Forked Palm. Kaba, Kodago, Kwalo (nut), Goriba (Dr. Dalziel’s Hausa list).

It is found in the Zaria and Niger provinces of Nigeria.

The only branched palm in West Africa. It attains a height of 30 feet. It is more or less gregarious in habit, though the individual groups of palms are not very large. It is apparently somewhat fire-resisting, though this may be due to its being found amongst the dry-zone vegetation. The stem is short and the two forks often crooked, so that little or no use is made of the wood by the natives. The seeds are turned into buttons, and so have recently obtained a value for this purpose. They were first sent to England from the Soudan, where apparently the tree is much more common than in West Africa.

Borassus flabelliformis, var. Æthiopica. Palmyra or Black Run Palm, Fan Palm, Bottle Palm, Arac Palm. Agbon, Olodu, Igoti (Yoruba); Oluwa (Benin).

It is a common tree in the dry-zone forest regions of Ibadan, Benin, Onitsha, and Ogoja provinces of Nigeria. This palm, with the swollen upper part of the bole making it appear more like a large inverted bottle, is thus not to be mistaken for any other. The huge fan-shaped leaves distinguish it from either the Coconut Palm or the Oil Palm. In the distance, too, the leaves appear more silvery-green, and not the yellow-green of the Coconut, or the bright, fresh green of the Oil Palm, or the sombre dark green of the Wine Palm. A large mass of coconut-shaped nuts, but with a smoother, more yellow surface, and more cylindrical in shape, without the ridges of the coconut, are another feature of this tree. At the base of each nut the old sepals of the flower remain, appearing like large dark-brown leaf scars. The young seedlings are easily seen amongst the grass, sticking up as they do like little silvery-green fans of varying size, in detail showing the folds of a fan most distinctly, the leaf opening out in a similar way to a fan. The bole is dark brown and practically smooth, showing no leaf scars, and only faintly lined vertically down the stem. The base is only slightly swollen, and the roots do not form a large mound round it, as is the case with the Oil Palm, and to some extent with the Tombo Palm. Inside the fruit there are two or three large, flattish nuts.

The timber is fibrous, hard, but very durable and quite termite proof. Although the upper part of the stem is hollow, long sectional pieces, four by two, and even thicker, can be cut out. It planes up with a smooth surface, and the grain looks very pretty with the thick fibres. It nails fairly well and splits longitudinally.

It is a light-loving tree, moderately fast growing for a palm. It is usually found growing gregariously in groups of a few acres up to hundreds of acres in extent. However, it is rarely thick enough to thoroughly shade the ground. Natural regeneration is good, even though in most areas annual grass-fires run through the trees and to some extent char the fruit. No plantations have been made of these species.

The timber has not been exported, but locally it has been used for house-building, as well as for fences near the railway. The natives occasionally use it for house-building, but they do not know how to tap it for the wine. The leaves are sometimes used for making temporary shelters. The fruit is sometimes eaten, and has a pleasant taste. The nuts might be exported for making into buttons.

Cyanastraceæ.

Cyanastrum cordifolium. Ikoto.

It has an edible fruit. Found in the Benin province of Nigeria.

Liliaceæ.

Dracæna sp. Dragon’s Blood. Ewanenimi (Benin).

It has a very long, thin leaf of the usual monocotyledonous type and with a somewhat branched stem, with thin papery bark.

It is fairly common in the Benin country. It is one of the few monocotyledonous trees of the forest, and thus easily distinguishable from other trees. The parallel veins of the leaf are very long and laid fairly close together. The stem is very porous and not woody, being more fibrous in type. It reaches a girth of about 4 feet and a height of 40 feet.

Native Use.—The leaves are used by the natives medicinally; and occasionally the sap is used to blind people.

Dracæna surculosa. Dragon’s Blood. Ope, Igbo.

Is found in Olokemeji.

Dracæna cylindrica. Boundary tree. Peregun (Yoruba); Ukpogun, Ogihu (Benin).

Found in the Olokemeji Reserve.

Dracæna cylindrica. Boundary tree. Peregun (Yoruba); Ukpogun, Ogihu (Benin).

It has a wider and shorter leaf than the Ewanenimi tree, but again with the parallel veins, which are, of course, typical of the monocotyledon. It does not really form proper timber, but the stem is of a spongy, fibrous nature. It reaches a girth of about 5 feet and a height of about 50 feet. It usually has one stem, which is unbranched for a very considerable length, but sometimes a whole group will grow up in one place.

Both this and the former species are propagated very easily by cuttings. In fact, it is possible to take the end of a branch complete with the leaves and put it in the ground, when it will grow. It likes a comparatively deep moist soil, though it will stand any amount of drought without actually dying. It stands pruning well and grows moderately rapidly.

It is useful for making live fences.

Native Use.—Both Yorubas and Benis use the tree for boundaries, simply sticking cuttings in wherever it is wished to mark a place. “Ju-ju” places are also marked in this way. The leaves are used medicinally in Benin.

Dracæna Perrottetii. Boundary tree. Ope, Kanakan (Yoruba).

Found in the Mamu Forest.

Dracæna sp. Boundary tree. Oro Igbo (Yoruba); Uruaro (Benin).

A common Dracæna found in the Benin and Abeokuta provinces of Nigeria. It is often used for making fences to farms and boundaries for village or farm land, and for marking special “Ju-ju” places. The Benin people state that it has more latex than the other species of this genus.

Marantaceæ.

Clinogyne, syn. Donax cuspidata. Yoruba Soft Cane. Toto (Y.).

It is found in the Abeokuta province of Nigeria. It is a small soft cane which grows gregariously in groups from a quarter to half an acre in extent in the Olokemeji Reserve, to a height of about 5 feet, and has large, alternating, very fine parallel-veined leaves. Inflorescence, raceme or panicle-like bracts, deciduous. Some species yield starch or fibre. Toto is found quite abundantly in the middle of the Olokemeji Reserve. It is used for mat-making, and considered most valuable.

Orchidaceæ.

Polystachya sp. (Lindl.). Eme-ela (Yoruba).

It is found in the Olokemeji Reserve in the Abeokuta province of Nigeria.

Polystachya odorata. Afoma (Yoruba).

This is a parasitic plant, very similar to mistletoe, which attacks many kinds of trees and has recently been found on the six-year-old teak at Mamu and Olokemeji, in the Abeokuta province of Nigeria.

Ulmaceæ.

Celtis solenostigma. Hard Celtis (large). Ita (Yoruba); Ita, Uta (Ikale); Ohianamemme, Ohia (Benin); Omoin, Itako, Ita gangan (Egba).

It is found in the Abeokuta, Ibadan, Ondo, Benin, Owerri, and Ogoja provinces of Nigeria, in the mixed deciduous forest zone, where it is usually very prevalent. In many places it is almost gregarious.

It is a large tree 10 feet in girth, with smooth stem and large, long, thin buttresses. It has a bigger leaf (6 inches) than the other Ita, with a very prominent mid vein on the leaf.

The fruit is dark coloured. The root buttresses are very long and thin, extending sometimes 15 feet up the trunk of the tree. They are, however, shallower and thinner than in the case of mahogany and cotton trees. They merge gradually at an angle of about 15 degrees into the stem. The bole may reach a length of about 90 feet, and is usually very straight. The crown is compressedly spherical, rather shallow in proportion to the size of the tree, but fairly wide-spreading. Occasionally, if the bark has a yellow tinge, especially in smaller specimens, the tree may be mistaken for Opele, Schrebera Golungensis.

Timber is white and very hard, and splits well when it is dry. When dry it is inclined to be brittle, though it shows considerable lateral strength. The texture of the grain is fine, and it planes up with a smooth surface. It is liable to split with nails, but it saws well. Under cover it is durable; in the open, unless very carefully dried, it is liable to decay. When thoroughly dry it hardens very considerably, and is not attacked by white ants, especially when used in a suitable place. When dry it will float, but the wood is liable to become discoloured by contact with water.

As firewood it burns slowly, gently and steadily, giving out much heat. It is a fairly rapid-growing tree, at first shade-bearing and later somewhat light-demanding; in the older stages it scarcely protects the soil. Up to the pole stage it is a soil-improving tree, the leaves making a rich humus. Natural regeneration appears to be good. It does not sprout from the stump. Considering its size it is fairly wind-firm. No plantations have been made of this tree.

The timber has not been exported, not has it been sawn up for local use. Considering its prevalence, it deserves a trial.

Native Use.—It is considered the best firewood in Benin, and also used as firewood among the Yorubas.

Celtis sp.? Soft Celtis (small). Ita ita (Yoruba); Ohia (Benin).

It is found in the Abeokuta, Ibadan, Ondo, Benin, and Ogoja provinces of Nigeria, in the mixed deciduous forest zone, where it is very prevalent.

It is a medium-sized tree up to 4 feet in girth, with medium sized, thin leaves and white-coloured twigs. The stem is slightly scaly and yellowish-green in colour, especially in the upper parts. A very common tree in the deciduous forest. With its yellowish-green bark in the upper part of the bole it is very similar to Opele, Schrebera Golungensis, and can often be mistaken for it. The trunk, however, is not slightly pitted, as is the case with Schrebera. On the whole, this tree is shorter, reaching a height of about 40 feet. The root buttresses are much slighter than in the case of C. solenostigma, though they are of a similar shape, being very thin and merging gradually into the trunk to a height of about 5 feet from the ground.

Timber is white and fairly hard, but not durable. It hardens somewhat on exposure to the air. The texture of the grain is fine, but occasionally cross-grained. It planes moderately well, and takes nails moderately well also, more so than C. solenostigma. It saws easily and splits well.

As a firewood it burns steadily and slowly, giving out great heat. It does not crackle nor cause sparks.

It is a moderately fast growing, at first shade-bearing, and subsequently a light-demanding tree. During most of its life it is a soil-protecting and soil-improving tree. Natural regeneration is good. It sprouts a little from the stump, but not strong enough for purposes of reproduction.

The timber has not been exported, nor has it been sawn up for planks for local use. Being smaller than C. solenostigma, after trial it may not be found so useful, but it could be used for similar purposes.

Native Use.—Firewood of the best kind, and occasionally used as side house-posts.

Trema Africana. African Elm. Ehunogo, Ehrunbogo (Benin); Affi (Ibadan and Oyo); Afoforo (Egba); Offun (Lagos).

It is found in the Abeokuta, Ibadan and Benin provinces of Nigeria, in the mixed deciduous forests, where it is moderately prevalent.

It is a medium-sized tree with nettle-like leaves, which wither rapidly. It has a very thin, smooth bark. The fruit is small, thin and long, and is eaten by pigeons. It grows up where old trees fall in the forest, and is also a common tree in old farms. Medium-sized specimens are in general appearance, from a little distance, very similar to Iroko, and it can be mistaken for this tree. The crown, however, is narrower, and the foliage is somewhat thicker, and the leaves and branches are placed rather closer together than those of Iroko. The bark is slightly fissured, and does not show lenticels like the Iroko, especially not on the roots. In proportion to the size of the tree, the root spurns are larger than in the case of Iroko. It it usually found growing singly, whereas groups of Iroko are often common, or anyhow several are found in one locality.

The timber is white and of medium hardness, but very durable indeed. It is termite proof. It planes well, but does not split easily. It saws well and takes nails fairly easily.

It is of fairly rapid growth, at first shade-bearing, and later a somewhat light-demanding tree, with soil-protecting and soil-improving qualities. Natural regeneration only appears to be moderate. It sprouts from the stump.

The timber has not been exported, not has it been sawn up for local use.

Native Use.—The timber is used amongst the Benis as rafters and ceilings for house-building, as it is uncut or squared.

Trema affinis or T. Africana. African Elm. Afofero (Yoruba).

Found in the Abeokuta province of Nigeria.

Moraceæ.

Antiaris toxiaria. False Oroko. Oro Aiyo, (Egba) (Yoruba); Ogiovu (Benin).

It is a common tree in the Calabar, Ogoja, Owerri, Warri, Benin, Ondo, Ibadan and Abeokuta provinces of Nigeria.

It is a large tree, reaching a girth of 15 feet and a bole length of 70 feet, of very cylindrical shape. There are large surface roots, which stick up out of the ground on roadsides, but form only low root spurns. The bark is grey, smooth and almost shiny in the sun. The crown is heavier and less open than Iroko, but otherwise in habit it is similar. The leaves on the whole are smaller and the foliage generally is of a lighter green than the Iroko, except when the latter puts on new leaves in February or March. The fruit is a little spherically shaped nut with a papery covering easily removed, disclosing a round nut with small markings all round it. Two kernels are found inside on cracking it. The slash is yellowish white, and gradually a little thin white latex exudes. The tree usually appears after a few years on abandoned farms. The leaf is rough to the hand, almost as bad as Ficus asperata, but there are no hairs on the under surface. On the whole the branches are much flatter than Oroko, though the top of the crown is round. The timber is soft and white all through. Termites attack it. It is very light and might almost pass as a substitute for cork. It has large and wide medullary rays, more especially in the root. In cross section the root looks almost porous.

Native Use.—Amongst the Yorubas the bark is used medicinally and the wood for doors, benches and matchet handles.

It grows very fast and likes light. Scale insects like to make their nests in a junction of a branch with the stem, where there is quite a hollow. In youth the firm and almost horizontal branches are quite a contrast to the long, up-shooting or drooping branches of Oroko. It has not been cut either for local use or for export.

The roots are used for making corks in the Calabar district.

It is used often as a “Ju-ju” tree, like the Iroko, chiefly in the Calabar Division. The hunters sit near the tree, when in fruit, because the Maxwell’s Duika, Yellow-backed Duika, Red-headed Duika, etc., eat the fruit. The bark is used in sections for making bags by sewing the two ends together, as well as one side.

Antiaris sp. Ovu (Benin).

It is a common tree in the Benin and Ondo provinces of Nigeria. It is medium-sized, reaching a girth of 9 feet and a bole length of about 50 feet. The leaf is larger, but the crown appears thicker and heavier than Antiaris toxiaria. The seed is the same size as Antiaris T., but the root spurns are very slight, even less than Antiaris T. The branches spread out from the stem, thus making the crown longer and narrower than Antiaris T. In this respect the Antiaris sp. is more like the Oroko than the Antiaris T.

The timber is white and soft. No proper heartwood. It splits well.

It is a shade-bearer and is often found in the thick forest. It grows much slower than Antiaris T.

It has not been cut for local use or exported to Europe. Perhaps it could be tried for wood pulp.

In Benin the branches of this tree are used for making figures of their ancestors, which are placed outside the house. The bark is used for making bags in a similar way to that of Antiaris T. It is also used for making rope or string for tying bags.

Antiaris sp. Cedar-like Lauro. Oregbon I (Yoruba); Opputtu (Benin).

It is a common tree found in the Benin and Abeokuta provinces of Nigeria. It is very similar in habit and shape to the Antiaris toxiaria, but it does not attain nearly such a large size. The tree exudes very fine, white latex in a very small quantity. The timber is soft and white and not durable.

To face p. 250.

It is a soil-protecting and soil-improving tree, and stands a good deal of shade. The tree has not been cut for local use, nor has it been tried as a timber for export.

Ficus sp. Common Fig. Obobo (Yoruba); Ohau (Benin).

It is a common tree of the Calabar, Ogoja, Owerri, Warri, Benin, Ondo, Ibadan and Abeokuta provinces of Nigeria. One of the most typical features of this tree is its free growth, open crown, and green, yellow and orange-coloured bark from the base upwards. It is a medium-sized tree, attaining a girth of 10 feet. The small red-coloured figs attract pigeons especially, as well as other birds, to the trees in the fruiting season. The leaf is small for a Ficus and oval in shape. The wood is white and soft. The white latex which exudes from the trunk when cut distinguishes this tree from the satinwood, Afrormosia laxiflora, with which it might be confused owing to the similar shades of green, yellow and orange-colour of the bark. It is chiefly found in the secondary forest, also near villages in the evergreen forest zone. Owing to the parrots and pigeons carrying the seed, reproduction from this source, both in epiphytic and tree form, is very good, but it is most usually found growing alone in an open place, without any support from other trees. It is very fast growing and impatient of shade.

The wood has not been used locally nor for export, nor does the native apparently have any use for it, as it soon rots when cut down.

The native occasionally eats the ripe fruit.

Ficus exasperata. Emido, Oboba (Yoruba).

This tree is found in the Abeokuta province.

Ficus Thonningii. Opoto (Yoruba).

This is one of the smaller fig-trees of the mixed deciduous zone. As with the others, it is not used as a timber tree, but occasionally for fences.

Ficus triangularis. Abadan (Yoruba); Obadan-nikwi (Benin).

It is a common tree in the Benin, Ibadan and Abeokuta provinces of Nigeria. It is chiefly found in the mixed deciduous forests. It is of no use as a timber tree, but is used occasionally for fences by the natives.

Ficus Vogelii. Lagos, Abba or Abbo Rubber. Abadon (Yoruba); Obadan (Benin).

It is the common tree of the Calabar, Ogoja, Onitsha, Benin, Ondo and Abeokuta provinces of Nigeria. This is the most common fig-tree, and is usually found along the sides of roads in the native villages. The very large, shiny leaf (not quite as glossy as Ficus Indica) is one of the most typical features of this tree. In Benin it is usually deciduous for about thirty-six hours, and the pinkish tips of the fresh leaves and the great rapidity of their development are remarkable. The bark is dark brown and rougher than the other species. In the Benin Forestry Compound there is a large specimen. On the whole, it is less common in the evergreen forest than near villages or roads. In the forest it is most often found as an epiphyte growing on oil palms, Sasswood, and oil-bean trees. The timber is white and soft; it has not been used for local purposes nor for exports. The “Balata rubber” of the Upper Niger district is obtained by roughly coagulating the latex of this tree in the air, with or without reagents, such as the latex of Bauhinia reticulata, or salt. The natives use the tree for making fences by sticking in pieces of the stem of suitable length, and in a similar manner it is used as a shade tree on the sides of roads in the villages. This is more especially the case in the villages in the dry zone, where other shade trees are scarce. Pigeons and parrots spread the seed, and thus its reproduction is assured.

Ficus platyphylla. Gambia Rubber.

It is also found in the upper reaches of the Ogan River, in the Ogo province of Nigeria.

Ficus asperata. Sandpaper Leaf. Ekpin (Yoruba); Ameme (Benin).

It is a common tree in the Ogoja, Owerri, Benin, Onitsha, Ibadan, Ondo and Abeokuta provinces of Nigeria.

It is often found as a small, scrubby tree, though when fully grown it reaches a girth of 8 feet, especially in the Benin province. The rough leaves are harsh to the touch.

The pigeons are very fond of eating the fruit and seeds.

The wood is white and soft.

The leaf is of the usual Ficus style, with a short stalk and deeply dentated, making almost a five-lobed leaf.

The leaves might be useful as a substitute for sandpaper. It has not so far been cut for export or local use.

Native Use.—The leaves are used for cleaning calabashes by the Yorubas and Benin people.

Ficus sp. Ograw (Yoruba).

Found in the Abeokuta province.

Musanga Smithii. Cork-wood or Umbrella Tree. Agbawo or Aga (Yoruba); Ogohen (Benin); Oro (Brass).

It is a very common tree, found growing in new clearings amongst the evergreen and mixed forests of the Calabar, Ogoja, Owerri, Onitsha (?), Warri, Benin, Ondo, Ibadan and Abeokuta provinces of Nigeria.

It is a medium-sized tree with an umbrella-shaped crown. It is the most distinctly gregarious tree of any in the forest, often alone covering many acres of land, supported on a series of aerial roots, the centre one of which is really the tap-root. The tree looks altogether top-heavy when mature (it is short-lived). It reaches a girth of nearly 5 feet. The bark is thin and of a light brown colour, spotted here and there with large yellow lenticels. The large pink sheath containing the immature staminate flower is often found lying on the forest pathway after the storm. The leaf is reminiscent of the horse chestnut, but with about eight digits. The young leaflet is of an orange-red colour. It is doubtful if it passes an age of thirty years.

The timber is white and soft, with no distinguishing heartwood, but with brown pith half an inch in diameter. When properly dried it has a fine, smooth grain and is usually free of knots. It dries much harder than when freshly cut. It splits well, but it is rather brittle.

It is the quickest growing of all the African forest trees, and certainly reaches timber size before any other. Regeneration by seed is prolific, seeds often germinating after lying dormant for over a hundred years, when a heavy forest is cut down. It is a light-lover, protecting the soil with its heavy foliage, and enriching it by making a good mould when it falls to the ground. It will stand a little shade as a young seedling. Very few trees will grow under it, though it is a useful “nurse.”

The timber is used for floating other wood heavier than water, but it has not been exported or cut for local use. The roots are used medicinally, and hunters tap the tree for water in the dry season.

Native Use.—As the Yoruba name implies, a group of the aerial roots is used for a native chair. Young 6-inch stems, split in half, cut about 4 feet long and dried, are used upright to form the walls of temporary farm-buildings. The wood is also used in place of cork, and for making matchets and knife scabbards in the Benin and Ibo countries respectively.

Chlorophora excelsa. African Oak, African Teak. Iroko (male), Iroko (female), Oba’s Tree, Rock Elm. Iroko (Yoruba); Uloko, Oroko Ulokoodigpe, Uloko-nushinogbon (Benin); Odji (Ibo, Asaba); Ofryio (Efik); Nsan (Oban, Ekoi).

It is a very large forest tree, reaching a girth of 30 feet and a bole length of 90 feet under favourable conditions. The male tree is usually thinner and of more compressed build, whereas the female shows more spreading growth and larger size; it is also quicker growing than the male. The female has stout, finger-thick, solid catkins, whereas the male has thin, long, open catkins up to 6 inches long. The timber of the male is darker brown and closer grained than that of the female, and also harder. The sapwood is wider in the female tree, but there is also a very wide difference between trees of both genders when they are grown in the open, old farms, or in dense, high forest, the latter yielding the hardest and closest-grained timber. The crown is almost umbrella-shaped and open, so that the leaves appear large in proportion, and it is usually possible to see through it. Three or four large limbs form the mainstay of it (see plate No. 37). The yellow lenticels on the stem, especially in younger specimens, and also on the red roots, are typical of the tree. The slash is yellowish, with little red spots in it. A little white latex flows out too.

In proportion to the size of the tree the root spurns are not very large, reaching 3 or 4 feet up the tree, and being well rounded, do not spoil the shape of the base of the bole. In older specimens the bark becomes brown, and finally almost grey in colour, and scales off to a slight extent. Although it forms very large side roots, it has a tap-root going to considerable depth. The loose seeds are small and flat, being not unlike those of alder, but rather larger and thinner.

It is found in all the Southern Provinces of Nigeria, both in the evergreen and mixed forest zones, where it is none too prevalent.

Timber.—Sapwood is yellowish white, and the heartwood of a yellow brown to dark brown (oak to teak brown). It is moderately hard, very durable and termite-proof. It does not plane very well, being sometimes cross-grained; it can, however, be worked up to a smooth finish. The grain is rather open and the pores very long. It has, however, an oily feel, and a certain amount of sheen. It takes nails with difficulty, splits moderately well and saws easily. It soon darkens on exposure to the air and light, becoming in this respect much darker than oak in a similar period. When seasoned properly it does not warp excessively. If taken green from the forest zone into a drier climate it will split. In the past a good deal of timber has been used in this state.

It is a moderately fast-growing, at first shade-bearing and subsequently a light-demanding tree, with soil-protecting and soil-improving qualities. It is deciduous for a few weeks in the year, generally in February or March, but specimens vary a great deal in this respect. Natural regeneration is very good, and in suitable localities it tends to spread more and more with the advance of the native farms into the forest. It stands transplanting very badly. Nursery sowings, however, show an enormous percentage of germination, the seedlings often coming up more thickly than grass. The ground pig eats the roots of transplanted seedlings, especially in localities where there are less desirable trees. It will grow as much as 6 feet in one year, and wherever it has much light in the forest, self-sown seedlings will grow 3 or 4 feet each year. The leaves are attacked by a minute coccus which causes them to swell up into an irregular shape, including the bud, thus stopping the growth for that season. Inside each of these swellings there are several of the young insects. Only the younger trees are attacked, and from the pole stage onwards trees do not appear to suffer nearly so much. In localities, too, where the trees grow very rapidly they appear to be less attacked, if at all. It is not very susceptible to fire, though in the mixed deciduous the base of the stem is often burnt. It is one of the most storm-firm of all the African trees. The bole is very cylindrical, especially if the tree which has been growing in the forest is given plenty of space to grow. The increment put on the bole is very great, being as much as 11 inches in circumference in one year.

In 1906 sample logs of this timber were sold in the Liverpool market as Iroko at 5d. per superficial foot, sale measure. Since that date it has been sold as African Oak and African Teak at a similar price, and appears now to be fairly well established in the market. As there are large supplies in many districts, such as the Yoruba country, Onitsha, Ahoada and Ogoja districts, there should be no difficulty in keeping the market supplied with moderate quantities year by year, at perhaps, though, slightly increasing costs. Locally the tree has been felled and sawn up for planks, scantlings, rafters, beams and general constructional work. By the Railway Administration it has thus far been considered the best wood for sleepers. Amongst the natives it is often worth more than it is to the European, the price varying from half a crown to 4s. 6d. per cubic foot for sawn boards 12 feet long, 12 inches wide and 1 inch thick.

Native Use.—The most valued of all woods for wall-plates and door lintels, treasure-boxes, washing-basins for chiefs. Doors, too, are made of it in Benin. Women place little pieces of chalk, yams, plantains, cowries, coco yams at the base of the tree, and it is said they will be blessed with children. Chiefs sacrifice a goat with a mat and a fine white cloth to propitiate the witches, who are supposed to hold their court in the Iroko tree and try to catch one of the sons of the chief.

Treculia Africana (Decne). African Breadfruit. Afon (Yoruba); Ije (Benin); Ijeni (fruit).

This tree is usually found near the edge of the villages of the Calabar, Benin, Ondo and Abeokuta provinces of Nigeria.

It grows to a large size, with a bole length of 20 feet and a girth of 9 feet, but it is usually a rather open-crowned, spreading tree. For its size the foliage is not over-dense. The leaves are single and roughly lanceolate, with a dark-green and rather shiny upper surface. The most conspicuous feature of this tree is the huge green, perfectly spherical-shaped fruit. Immature fruits of all sizes, from a cricket-ball upwards to a size of 18 inches in diameter, are seen growing close against the stem of the trunk and bigger branches of the tree. Some years ago, one of these ripe fruits fell off a tree at the edge of the Benin market and struck a woman on the shoulder with such force that she died a few days later. The natives subsequently cut the tree down.

The chief use of the tree is the fruit, which is placed in water to rot so that the seeds can be more easily extracted from the concentrically arranged fibres growing from the centre of the fruit outwards to the periphery. These are subsequently cooked and eaten, often being beaten up in a soup. From the outside the fruit looks as if it were made up of thousands of little green fibres closely packed together from the centre of the fruit, with the ends sticking out on the surface, thus giving it a rough feeling to the touch and making it appear as if it were full of holes.

The junction of a branch with the stem shows a large swelling all round the base of the branch, which thins out to its regular size about 6 to 9 inches away from the trunk.

The tree is comparatively slow-growing, but of a soil-protecting and light-loving nature. In the dry season, great quantities of dew condense on this tree, so that underneath the soil is kept moist. Probably more dew falls on this tree than Myrianthus arboreus, which shows a similar feature.

Thus far the wood has not been used for any purpose.

Treculia sp. Small-fruited African Breadfruit. Izenagan (Benin).

Found in the Benin province.

Morus sp. Aye (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province in Nigeria.

Myrianthus arboreus. Shapo Obibere (Yoruba); Ihege (Benin).

It is a small to medium-sized tree, with short stem rarely exceeding 8 feet in height, and a much-branched, heavy crown, with very large leaf, cut up in the form of a large digit, much more pronounced than the horse chestnut. The leaves, on falling, rot and form a heavy layer of black humus. In the dry season the dew condenses to such an extent on the leaves that the tree drips in the morning, and the neighbourhood of such trees is always moist when the rest of the forest is dry.

The large, rough, elongated, pear-shaped fruit, like an overgrown sweetsop, is quite characteristic of this tree.

It is found in the Ondo, Benin, Owerri, Warri, Calabar and Ogoja provinces of Nigeria.

It is scarcely big enough for timber, but would make a good undergrowth for a light-loving species such as mahogany or teak, and would kill all weeds on good soil. Usually found on good soil. The timber is white and soft.

No botanical name. Iragbo-Amuje (Yoruba); Igogo (Benin).

It is a large tree with almost hard white wood, more the texture of Triplochiton. The fruit is a drupe, with a small nut inside. Termites do not attack the wood. It is a quick-growing tree, which comes up very frequently in old farms.

It is a common tree in the Benin country.

It is a shade-bearer.

Native Use.—In the Benin country it is used for door lintels and cross-pieces in house-building.

Urticaceæ.

Urera. Ela (Yoruba); Akinrankiri (Benin).

Found in the Yoruba and Benin countries.

Proteaceæ.

Faurea speciosa. Red-brown timber.

Found in the Calabar province.

Olacaceæ.

Heisteria parvifolia. White Nut (?). Ikereoha (Benin).

It rarely exceeds the height of about 8 feet and a girth of about 1 foot.

This is a small shrub with red flowers of four petals at right angles to each other, in the middle of which a white-coloured fruit forms. On peeling off the white skin, a black nut is disclosed, which is edible. It tastes more like a hazel-nut. The red flower is the most distinguishing feature, and makes this plant show up amongst the evergreen zone.

It is found in the Ondo, Benin, and Calabar provinces of Nigeria.

It is a shade-bearing and slow-growing shrub, with soil-protecting and soil-improving qualities. It serves a very useful purpose amongst the undergrowth in the forest. Natural regeneration appears to be fair, but no plantations have been made with this species. The nuts have not been tested in the export market. Amongst the natives the nuts are very popular, and it is the only use which they have for this shrub. This chiefly refers to the Benin district.

Heisteria sp.?. Benin Nut, Edible Nut. Evialegbi (Benin).

It is found chiefly in the Benin province of Nigeria, though probably its area of distribution extends to the Ondo and Ogoja provinces as well. It is a tall, comparatively thin-boled tree in proportion to its height. Attaining a girth of about 8 feet, the bole is 40 feet in length. The bark is dull green and not very thick, being more in the nature of cortex than real bark. The most typical feature of the tree is the fruit, which is a spherically-shaped nut with a pointed tip. When dry, it is marked with shallow groves about half a millimetre apart, all converging to the tip. When cracked, the kernel obtained is rather pleasant to the taste, with plenty of oil. The timber is a yellowish colour and moderately hard. It is fairly durable, though it is attacked by a small wood-borer when it is left lying in the forest. It is a moderately fast-growing tree, but is a shade-bearing, soil protecting and improving tree. Natural regeneration appears to be poor. No plantations have yet been made with it, but its yield of nuts should be tested. The timber has not yet been exported, nor has it been cut for local use. So far, the chief use of the tree is the nut, but even here proper tests have not yet been made, and it is only the natives who really know the tree. The exact oil content has yet to be tested.

Coula edulis. Nkula in the Gaboon, Gaboon Nut. Omumu (Benin).

An edible nut containing oil. It is nearly round in shape, but slightly depressed at the top, with a soft shell.

Chief Characteristics.—The tree is of medium size, with narrow crown and small leaves, the fruit being borne on the upper side of the branches. It is moderately common near Ugo and also on the Siluko road (both in Benin). This is apparently a rare tree in reality, and it may be mistaken for Ivialegbi.

The timber is brown with a red tinge, almost hard.

Native Use.—The nut decorticated is sold in the native markets and eaten as a delicacy.

Value.—According to report made some years ago, it was valued at £7 per ton in Liverpool. It was difficult to get sufficient for a sample.

Loranthaceæ.

Loranthus leptolobus. African Mistletoe, or Red-flowering Loranthus.

Found in the Yoruba and Benin country.

Menispermaceæ.

Cissampelos Owariensis. Ebewaki (Benin).

A medicinal plant.

Cissampelos Pareira (L.). Jokoye (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Anonaceæ.

Enantia polycarpa (Kew). Abeokuta Bark, Kanda or Canta Bark. Ghido (Yoruba).

Found in the Egba province.

Enantia chlorantha. African Yellow Wood. Yaru (Yoruba); Ehranbabogo (Benin).

It is a common tree of the Ondo, Benin, Owerri, Ogoja and Calabar provinces of Nigeria.

It is a medium-sized tree, attaining a girth of 5 feet and a bole length of 25 feet. The most peculiar feature of the tree is the fruit, a bundle of reddish clubs all coming out of the twig at one point. The stem is dull green, with scattered lenticels here and there. The bole is uneven near the base and almost divided by large spurns, which makes it difficult to cut out a square log. Standing in dense shade usually, and often with a piece of the bark removed, showing the yellow cambium layer or wood, it is easily distinguished from other trees.

The yellow wood is similar both in the sap and in the heartwood. It splits well, even into tiny thin, lath-like pieces. It is soft, but planes up into a smooth surface. The medullary rays are often prominent, and make the wood look very pretty. The sheen of the wood also adds to its appearance.

The tree is a shade-bearer and rather slow-growing; perhaps in more open localities it would grow faster. Natural regeneration does not appear to be good, though more extensive observations on this point may reveal more. Small quantities of seed are borne each year. It sprouts a little from the stump, but this method of reproduction cannot be relied upon. Cuttings have not yet been tried. It likes a good moist soil of the evergreen forest and lower parts of the mixed deciduous forest. It has not yet received a place in the forest plantations.

Samples of the timber have been tried in England and used with good effect as a substitute for American “Whitewood,” to which it is similar in texture. Its small size rather hinders its more extensive use. In the Benin district it is used as cross-pieces and rafters in building; wooden shovels are also made from it. It is occasionally used to make a yellow dye, especially the bark. Native caps are made from the bark, which is fibrous. It is also used for verandah-posts and door-frames.

Dennettia tripetala. Igberi (Yoruba); Ako (Benin).

It is a common tree in the Benin, Ondo (?) and Abeokuta provinces of Nigeria.

It is a medium-sized tree, reaching a maximum girth of 6 feet, with a short bole and a much-branched crown. Most commonly seen as a shrub-like tree in the mixed deciduous forest. The flower has three petals, with red colour inside and brown outside. The flowers grow on the stem or the twigs with little or no stalk, usually two or three in one place.

The timber, which is white and soft, is eaten by termites. There is no proper heartwood.

It is a shade-bearer, and rather slow-growing tree. It likes good soil, and is rather an indication of a loose, good and deep soil.

It has not been exported or used locally.

Native Use.—The fruit, which has a peppery taste, is eaten. The chiefs only eat the fruit after it has become red and really ripe. The small boys use the new young leaves uncooked to make the mouth warm when the rain falls.

Dennettia sp. Agedegbo, Ako (Benin).

This tree was determined from specimens obtained in the early part of 1917 from Olokemeji, where it is somewhat common. Owing to the fact that only immature and mature fruiting specimens were sent, it may be identical with Dennettia tripetala. It is, however, a much smaller tree, and the fruit is not nearly so large and is a more oblong shape than D. tripetala. It is a small, much-branched tree and yields a hard, whitish-yellow wood which might be used as substitute for lancewood. The Benis eat the fruit, but the Yorubas have no use for the tree.

Xylopia Æthiopica. Negro Pepper. Eru (Yoruba); Unie (Benin); Atta (Efik).

Is a medium-sized tree with silvery smooth, grey trunk, and found growing near the banks of rivers in all the southernmost provinces of Nigeria.

To face p. 260.

It is stated to be useful for oars and masts for small boats, according to the report on the Exhibition of 1867. Since that date, however, it has not been used for this purpose. The bole reaches a girth of about 5 feet and a length of about 45 feet. The crown is narrow and comparatively long, but rather compressed and compact. The foliage is dense and comparatively close together. The root spurns are slight and narrow, not extending very far up the bole. In proportion to its height the trunk is thin and very cylindrical in shape, though occasionally near the base it may not be absolutely round and tends to bulge out rather more on one surface than the other. The fruit, when ripe, is like a bunch of black keys, or little short, round-ended pieces of wood, all projecting out of one central stalk or fork, which is the most typical feature of the tree. The cortex is comparatively thin, and remains smooth even in the mature trees. The bole tapers only very slightly, and does not divide or send out any branches until the crown is reached.

The sapwood is white, as also the heartwood, except that the latter tends to have a very light yellowish-brown tinge, especially as it seasons. It is moderately hard, showing great elasticity, planing with a smooth surface, splitting moderately well, taking nails and not warping or shrinking to any great extent. Even fresh it is comparatively a dry wood. It saws well and shows considerable textile strength, as also strength in compression, is moderately heavy and termite-proof. The texture of the grain is very fine and even, and the grain is very straight.

This tree is somewhat slow-growing, shade-bearing, soil-protecting, and soil-improving. Natural regeneration is moderate. It does not sprout from the stump. It stands a certain amount of flooding, but it seems to demand a good soil with plenty of moisture, including a very moist atmosphere. No plantations have been made of this tree.

The timber has not been felled for export, nor has it been cut for local use, but it appears to deserve a trial as a substitute for lancewood, or other woods which show considerable elasticity. It should be noted that it belongs to the same family as that of the lancewood. Owing to the straightness and comparative evenness of the bole for a very considerable length, it might be suitable for shafts or even telegraph poles.

The fruit is used as a kind of comestible amongst most of the natives, as it has a peppery taste which is not unpleasant.

It is usually dried and sold in the native markets, several bunches for a penny. By some it is almost looked upon as a medicine.

Xylopia parviflora (Eng. and Diels). Small-flowering Negro Pepper. Sesedo, Issa oku (Yoruba); Aghako or Oziza (?) (Benin).

This tree is found in the Abeokuta and Benin provinces of Nigeria, where it is none too prevalent. It is a medium-sized tree with a very straight, thin and tall bole. Except for its size it is very much like X. Æthiopica; the fruit is much smaller and scarcely to be seen from the ground. The timber is grey-white, and the heartwood, though occasionally a light brown, is scarcely to be distinguished from the sapwood. It is hard, durable, and said to be termite-proof. It does not take nails easily, nor does it split well, but it saws comparatively easily. Natural reproduction by seeds appears to be poor. It scarcely sprouts from the stump. It is a shade-bearing, soil-protecting and soil-improving tree.

The timber has not been exported. The bark and roots are used medicinally.

It is used locally for house-building, as verandah-posts or supports for the roof. It has considerable tensile strength and stands compression better still.

Anona Senegalensis (Pers.). Wild Custard Apple. Abo (Yoruba).

This is found in the Oyo and Ogoja provinces of Nigeria. It is a small, shrub-like tree, with a short stem of about 4 or 5 feet, and has a very oval leaf, almost ovate in shape. It bears a yellow fruit which divides up into the typical segments common to this family. It resembles the Sugar Apple, has a delicious taste, and the fruit is most refreshing on a hot day at the end of the dry season. The tree is fire-resisting. Being deciduous, it is not a soil-improving tree. It is soil-exacting, but is also found in rocky localities. The tree is not very prolific, but sprouts very strongly from the stump and to a less extent with root suckers. The small timber is occasionally used for house-building.

Anona palustris (Foster). Alligator Apple. Afe (Yoruba).

The wood is supposed to be soft, and to have been introduced into the country some years ago.

It is found in the Abeokuta province of Nigeria. The fruit is edible, the foliage dense and heavy. In the dry season the dew condenses on the leaves and towards morning drips off on to the ground, thus keeping the immediate vicinity of the tree quite moist. The leaves, when decayed, make a rich humus. It is one of the most valuable soil-improving trees.

Anona Mannii.

It grows in the forest region of the Central and South Provinces of Nigeria. It is a medium-sized tree bearing large green fruit close to the stem.

Popowia Mannii.

A specimen of this Popowia has been found in Alasko, near the Oha River in the Ibadan province of Nigeria.

Anona Afzelii. Probably the same as Dennettia sp. Ako, Aggedegbo (Benin).

It is found in the Abeokuta, Benin and Warri provinces of Nigeria.

It is a medium-sized tree of the more swampy parts or moister regions of the evergreen forest zone. The leaves are a very large size, often reaching a length of 1 foot. The wood is yellowish-white and soft and not very durable. Owing to the very dense foliage, quite a thick layer of humus is formed in the shade of the tree, so that its soil-improving properties are very great. It would be a valuable tree for underplanting mahogany or any deciduous tree, both with a view to providing soil cover and improving the soil.

The natives do not use this wood.

Hexalobus grandiflorus (Benth.) Afara (Yoruba).

Found in the Abeokuta province.

Uvaria Afzelii. Gbogbonshe (Yoruba).

It is found in the Abeokuta province of Nigeria. A small tree with hard wood.

Uvaria Busgenii. Paddlewood. Umaja or Umazza (Benin); Uruiju Arogu (Yoruba).

It is found in the Calabar, Ogoja (?), Benin, Ondo and Abeokuta provinces of Nigeria.

It is a large tree, and reaches a girth of about 10 feet with a good bole and limbs. The crown is narrowish, being formed by many small branches. The bark is light green, scaling off and leaving yellow patches with a red edge to each; otherwise it is smooth and almost shining. It is a common tree of the evergreen forest. With the exception of slight hollows near the base of the stem the bole is quite round.

The timber is a faint orange-colour with a reddish tint. There is very little difference between the heart and sap wood, except that the former is a lighter colour. It splits well and planes into a smooth surface. At the corner of a square block pieces are liable to split off. The grain is a little open and the pores are rather long.

Termites (white ants) make no impression on it. The timber is hard, with a certain amount of rigidity, and yet has no resilience.

It is a slow-growing tree and shade-bearer. Judging by the number of small trees found, reproduction from seed must be good. It does not sprout from the stool, and root suckers are thrown up after the trees have been felled. It likes moist and deep soil, which must be moderately good, e.g. the red soil of Benin and sandy loam of Badagry district.

In 1906 samples of the wood were sold in the Liverpool market as Sabicu and realized 1s. to 2s. per superficial foot. It has also been used for European house-building in the Calabar province.

Native Use.—It is chiefly used for making paddles. It is also used for joists and posts by the Benin people.

Uvaria Chamæ (Kew). Eruju (Yoruba).

It is a large shrub with sweet-scented flowers. Lagos Island.

Artabotrys sp. Ako gbogbonshe (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Monodora tenuifolia. African Nutmeg. Lakosin (?) (Yoruba); Unyenghen (Benin).

In younger trees there are a few narrow white streaks in the dull green bark, which gives it quite a distinctive appearance.

Chief Characteristics.—It is a medium-sized tree with yellow flowers tinged with white, most conspicuous after they have fallen to the ground. The flower has three petals with wavy edges, and reminds most people of an orchid. In fact, many have asked whether it is not an orchid. The leaves are light green, especially on the under-side, though darker as the rainy season advances. The fruit is a spherical drupe, containing several small nuts or seeds. The tree flowers before the leaves come fully out, so that it looks very handsome indeed. It is, in fact, one of the prettiest of all the flowering trees. It flowers at the end of February or at the beginning of March. It reaches a girth of about 2 feet and a bole length of about 10 feet, though it is often much branched from about 4 feet from the ground.

It is quite common in the Abeokuta province of Nigeria, especially in the Olokemeji Reserve and on the road between that place and Mamu, in the Benin province, as well as being found in the mixed deciduous forest zone.

The timber is hard and white and fairly durable. It is tough and does not split well.

Although it stands a little shade it is a somewhat slow-growing, light-loving tree, but does not protect the soil. Natural regeneration appears to be fair. It sprouts well from the stump, often in this way forming quite a clump. On these stool shoots it bears flowers and fruit early. It transplants badly, more especially when placed in the open. It is somewhat exacting as to soil, demanding a certain amount of moisture as well as depth. It is somewhat fire-resisting, sprouting out again after such injury.

As it does not really reach timber size, it is not of much use for local constructional purposes.

Native Use.—The smaller trees are used as walking-sticks and the larger ones are sometimes used for hoe and axe handles. In clearing the land for farms, stool shoots are left standing, to act as supports for the tendrils of the yams after they have been planted.

Monodora myristica, var. grandifolia. Calabash Nutmeg. Lakoshe or Abo Lakoshe, Ilakosin, Igbo (Yoruba); Ukposa, Eddo Binoyoba (Benin).

It is found in the mixed deciduous forests of the Ibadan, Ondo, Benin, Owerri, and Ogoja provinces of Nigeria, where it is somewhat prevalent.

Chief Characteristics.—It is a large tree, up to 7 feet in girth, with open crown and thin foliage. The flowers are very conspicuous when they fall, having three very large pointed red petals streaked with white, almost reminiscent of an orchid. The edge of the petal is wavy, too. On the tree, the flowers hang from the under-side of twigs with very short petioles. It is the most handsome and largest flowering tree amongst the Monodoras. It is, however, never quite so much covered with flowers as the M. tenuifolia. The flowers are considerably larger, being quite half to one inch longer. The bole reaches a length of about 15 feet, but is often branched lower down. The fruit is a large drupe, containing a number of small nuts.

The timber is whitish, hard and somewhat tough, and does not split well.

It is a moderately fast-growing, light-demanding tree. With the exception of the period when it loses leaves, it is a soil-protecting and soil-improving tree.

Although it scarcely reaches timber size, it might be tried for smaller constructional purposes, such as handles, posts, or rails. The quantities, however, are not very large.

Native Use.—The nut is ground up and used in soup.

Monodora brevipes. Yellow-flowering Nutmeg. Ause, Lakosin (Yoruba); Iyoha (Benin).

Grows abundantly throughout the Tropics. The seeds are useful as condiments or as medicine.

Myristicaceæ sp.

Pycnanthus Kombo. White Cedar. Akomu (Yoruba); Omocham (Benin).

It is found in the Calabar, Ogoja, Owerri, Benin, Ondo and Abeokuta provinces of Nigeria.

It is a very common tree, especially at the edges of roads and in old farms. It is not so common in the original forest. It grows up to 15 feet in girth. It has a very cylindrical bole, with long, straight, outstanding branches growing close together, more or less forming a flat crown. The leaves are large and pinnate, and the small fruit, which grows in clusters, half opens, disclosing a bright red interior with one round seed covered with pink, mace-like fibre. The slash is pinkish-white, and heavy, sticky white latex streaked with red exudes very freely after it has been cut.

The timber is soft and white and not durable. It has not so far been used either for export or locally.

Lauraceæ.

Ocotea cf. Egg-shaped fruit tree. Agkwokhau (Benin).

Found in the Benin province.

Capparidaceæ.

Cratæva Adansonii (Guill. et Perr.). Egun oran (Yoruba).

Tree 30 feet high with yellow flowers. Found growing at Fiditi, Oyo province.

Capparis Thonningii. Ekkana, Awoa (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Rosaceæ.

Parinarium sp. Babu (Yoruba); Oria (Benin); Oko (Ibo, Owerri); Oguru (Brass); Edat (Efik); Ukpoi, Edat, Mpuri (Oban, Ekoi).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria, and Asaba district, Benin province.

It is a large tree with irregular surface to the bole, muscular-like protrusions being seen here and there, as well as similar shaped depressions. The crown is wide and flattish, and of light foliage. The fruit is a large, nasty-smelling, apple-shaped drupe.

The timber is white, with apparently little difference between sap and heart wood, and it is hard and tough, not splitting at all easily.

It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree, said to be termite-proof. It has considerable resiliency, and stands a certain amount of bending strain.

The timber has not been used for export, nor has it been sawn up for planks for local use.

Native Use.—The Yorubas use the timber for making mortars for food.

Parinarium sp. Red Mahogany. Abue (Egbado, Yoruba); Dabadogun (Benin).

It is plentiful in the Benin and the Abeokuta provinces of Nigeria.

Chief Characteristics.—It grows into a large tree, but is often seen as a small tree, suppressed by other quicker-growing trees. The dense, somewhat spreading crown is a typical feature of the tree. Its large leaves attract attention, especially compared to the size of the tree. The bole is often crooked and covered with dark green cortex, with only a limited amount of fine bark.

It has a hard, red wood, not unlike mahogany, but with a more fibrous grain. It is durable, especially when left in a wet place. It works up with a good surface and very pleasing colour, making it thoroughly worthy of being a substitute for mahogany. Being a shade-bearer, soil-protecting and soil-improving tree, it should eventually find a place in the forest plantations. Despite its slow growth, its other silvicultural qualities are worthy of attention.

It has not yet been exported, not has it been felled for local use. For the former it appears to deserve a trial.

Native Use.—It is used for firewood.

Parinarium robustum. Sometimes called Mahogany Nuts, Nikko Nuts; Benin Mahogany. Ugibisaro (Benin); Aiyeni (Egbado); Aiye, Aghaghe, Aiyeni (Yoruba).

It is found in the Abeokuta and Benin provinces of Nigeria, in the evergreen forest zone, where it is not very prevalent. It is a large forest tree, reaching a girth of over 12 feet and a bole length of about 70 feet. In the dry season, in the distance, the leaves show the typical dried-up yellow appearance of the Parinariums, especially being somewhat shiny in appearance. The fruit is not unlike a very large, very dark green plum, but rather more flattened and not so round. The inside nut is compressedly spherical, showing five large eyes or holes out of which seeds germinate.

The sapwood is yellowish-white and somewhat broad in proportion to the size of the tree, and the hard wood is mahogany-red coloured, but with more fibrous grain. It planes up with a smooth surface and splits fairly easily, especially when nailed. It is moderately hard and quite durable, and is not supposed to be attacked by white ants (termites). Like most of the Parinariums, the fresh wood smells something like honey, and the timber tends to darken on exposure to the air, thus improving in colour.

On the whole it is a shade-bearing tree and not very fast-growing. It has soil-protecting and soil-improving qualities. Natural regeneration only appears to be very moderate. Like most of the Parinariums, the kernels of the fruit are pecked out by various birds. No plantations have been made of this tree.

Quite by accident, in 1906 some logs obtained from this tree were cut and exported, and sold in the Liverpool market as Benin mahogany at 4d. per superficial foot. Since then, however, none has been cut.

Amongst the Benin natives the timber is occasionally used for house-building.

Parinarium excelsum. Essago (Benin).

It is found in the Ondo, Benin, Owerri and Calabar provinces of Nigeria, in the evergreen forest zone, where in certain localities it is very prevalent.

In appearance it is like the rough-skin plum of Sierra Leone, but a larger and taller tree. The leaf usually looks dry and grey, especially underneath. The crown is oval and very dense, with a mass of large limbs. The bark is covered with white lenticels, which make it look grey. It usually bears a large crop of fruit each year.

It reaches a girth of over 12 feet and a bole length of about 50. In proportion to the height, the bole is not so long as in the cases of many other forest trees. The fruit is more uneven in surface than that of P. robustum, and the surface is also more or less speckled with little white raised lumps, giving it a roughness to the touch. The fruit inside is yellowish-white, rather hard and not unpleasant to taste. Where it is found, especially in the more swampy parts, it is often almost gregarious in habit. It is an evergreen tree.

The wood when freshly cut smells like honey. The sapwood is yellowish-white and the heartwood is brown. On the whole it is much harder than P. robustum. Occasionally it appears cross-grained, and does not plane up with such a smooth finish. It saws less easily, and it is hard to drive nails into it. It does not split well. It is rather a heavy wood and does not float.

It is a somewhat slow-growing, shade-bearing tree, which thoroughly protects the soil and improves it with its leaf fall. Natural regeneration appears to be none too good. No plantations have been made of this tree.

It has not been felled for local use, but occasionally it has been used for firewood, which is of somewhat high calorific power. The fruit is occasionally useful to temporarily assuage hunger in the forest.

It was sold as African greenheart at 1s. 6d. to 1s. 9d. a cubic foot in the Liverpool market in 1906.

Native Use.—None, and the fruit is not eaten. Elephants eat the fruit.

Parinarium polyandrum (Benth.) (?). Plum. Ako Idofun (Yoruba).

Smaller fruit than P. curatellæfolium and very hard; similar flowers, the leaves rough and only slightly grey-green on the under-surface. Stem reddish-brown with long lenticels, leaves larger and longer.

It is found in the Abeokuta province of Nigeria.

Native Use.—The tree is used by the natives for building farmhouses.

Parinarium curatellæfolium (Planch.). Abo-Idofun (Yoruba).

A small tree 10 feet in height and 1 foot in diameter, with large umbelliferous flowers of a white colour. The leaves are rough and shiny on the upper surface, and with more white underneath than the P. polyandrum.

Native Use.—The fruit is edible, though not usually eaten. No use as firewood. The wood is used for building farm-sheds.

Parinarium Gabunense. Mahogany Nut. Abere (Yoruba).

Found in the Ondo province.

Chrysobalanus sp. Niko Nut. Igata (Yoruba).

Found at Ebuttemetta.

Leguminosæ (Cæsalpineæ).

Cassia Sieberiana. Cassia. Aridan-toro (Yoruba); Ezzi, Apagban (Benin).

It is commonly found in Benin, Ibadan and Abeokuta provinces of Nigeria, more especially in the latter. It is a small tree bearing large and long racemes of yellow flowers in February, making it very reminiscent of the laburnum. The tree is leafless at the time, so that the flowers are all the more conspicuous. The almost rectangular branching habit of this tree, combined with the rather thin twigs, is very typical. It yields a hard, red wood, but the sapwood is yellowish-white. The natives use the fruit medicinally and the timber for house-building. The pods are usually about a foot long and half an inch in diameter.

Cassia tora. Cassia. Ako Kere (Yoruba).

It is found at Olokemeji, in the Abeokuta province of Nigeria. Its medicinal use as a remedy for ringworm is not known to the natives of that locality.

Cassia fistula. Cassia. Bembedo (Yoruba).

It is rather an uncommon tree of the Benin province of Nigeria, one specimen being found in the Idah district; the longer (1 to 2 feet) and stouter (¾ to 1 inch) pod is most typical of this tree. It is otherwise much the same size as Cassia Sieberiana. The natives use the fruit medicinally, but look upon the tree as a “great medicine.”

Cassia podocarpa (G. and P.). Cassia. Asunwon (Yoruba).

It is found in the Olokemeji Reserve.

Shrub with yellow flowers.

Cassia occidentalis. Blackwater Plant. Rere (Yoruba).

It is a small shrub-like herb with large upright flowers, which is usually found growing in waste places at the edge of villages in the Yoruba country, in the mixed deciduous forest zone. A medicine to cure blackwater fever is made from this plant, though doctors now say it is not an infallible cure.

Ormosia laxiflora (Benth.). False Dalbergia. Shedun (Yoruba).

It is found in the Ibadan, Abeokuta, Onitsha and Ogoja provinces of Nigeria, chiefly at the edge of the dry-zone forest.

It is a small tree, 12 feet high and 18 inches in girth, with almost brick-red or orange-coloured bark, which is thin and often scarred by natives. It has a long, thin pod with thin, flat seeds. It reminds one very much of a small Dalbergia. It stands the annual fires well, though it gets singed each year. The base of the bole is often somewhat enlarged with the constant cutting of the bark both of the stem and the uppermost roots.

The timber is yellowish-red and not very hard, but rough to work up, being more in the nature of a turner’s than a joiner’s wood. The grain is often by no means straight, and the wood shows a little figure.

Withstanding the fires so well, it serves, or should serve, as a nurse for the introduction of more valuable species amongst the dry-zone trees, especially on the laterite soils. Natural regeneration is good and it sprouts well from the stump. Root suckers do not appear to be so prevalent as in many dry-zone species. It is a light-loving species, which does not protect the soil properly, though the foliage is comparatively dense for that type of tree. It is slow-growing. No plantations have been made.

It does not attain sufficient size for export, but it might be tried for local turnery work. It is useful for local hut-building.

Native Use.—House-building, and the roots when boiled are used in medicine as a tonic.

Afrormosia elata. African Satinwood, Yellow Satinwood. Ayin (Yoruba); Anyeran, Anyesan, Ehranobapotineddo (Benin); Egbi (Ibadan); Elo Uta (Ibo, Owerri).

A very conspicuous tree, with its orange-red trunk near the base, gradually shading off to yellow higher up, and towards the branches a light-green colour. Large, irregular-shaped pieces of bark fall off from time to time, in a similar way to the plane-tree of Europe, though with its reddish trunk it is not so much like the plane as Afzelia Africana. The root flanges or spurns are very thin and do not extend beyond about three feet up the stem of the tree. In plate No. 82 one of these trees, growing near Benin, shows the open, rather narrow crown with its few main limbs supporting it.

It is commonest in the Benin, but also found in the Ondo, Owerri and Calabar provinces in the moist evergreen forests. It is also seen in secondary forests of the same zone.

The timber planes well, but does not split. It saws easily, but takes nails with difficulty. It is sometimes figured, especially logs from the base of the tree.

It is pretty easily killed by fire at the roots, though otherwise it tends to spread with cultivation. The sapwood is almost white and the heartwood a yellowish-green, when fresh, but a dull yellow when dry. It is very hard and withstands the attacks of white ants (termites). Even the sapwood of a young tree had not rotted after six years near the bank of the Ogba, Benin province. It grows moderately quickly.

The flower is inconspicuous and small, and the pod is also small, being about 2½ inches long and ½ inch broad, containing two or three flat seeds. The tree does not bear very heavily, and in consequence natural regeneration is not very good, though such seeds as actually form properly seem to germinate well. In youth it bears some shade, but in middle age seems to be almost a light-demander.

Although when freshly cut the wood does not float, when thoroughly dry it would not be difficult to float it with a lighter species.

The timber was reported as satinwood and worth 3d. to 1s. per superficial foot in the Liverpool market in 1906, and that moderate quantities (of fair length and squares) would be taken.

Pterocarpus esculentus (Schum. and Thon.). Edible-fruited Padouk. Gbingbindo (Yoruba); Akpanagya, Uruhe (Benin); Nja (Efik).

It is one of the most common waterside trees of all the Southern Provinces of Nigeria; some of the rivers on the banks of which it is found are the Ovia, Ogun and Cross River. Belonging to the mixed deciduous forest zone, it is in the middle reaches of these rivers where it is most prevalent.

A typical feature of this small tree is the bright, yellow-coloured flower, which quite brightens up the banks of the rivers at the end of February or March. Another most peculiar feature is the odd, somewhat kidney-shaped fruit with its rough surface corrugations, containing inside a hardish nut about 1 inch in diameter. Either the nuts or the fruit are often seen floating down the rivers, especially where they are tidal. The leaves are more typical of the Pterocarps, otherwise the fruit is most unlike either those of the genus or even of the family. The bole of the tree is short, smooth and almost silver-grey in colour, though it is often discoloured with the mud from the perennial floods of the river. It is usually seen with more than one stem.

The timber is white and not over-hard. It is not very durable.

The tree is not very fast-growing, but is an evergreen, with a short period in which nearly all the leaves fall. It serves a most useful purpose in holding the banks of the streams wherever it is found, and it is noticeable that its roots appear to extend a long way back and that it is one of the last trees to be washed out by floods. It sprouts fairly well from the stump when cut, unless it is almost at once submerged by the floods, which points to the fact that it should be cut only at the beginning or towards the end of the dry season. Natural regeneration appears to be fair, but no plantations have been tried with this tree.

The nuts have not been examined to see what they contain, though they are of nutritive value.

For export it does not yield large timber, and for local use it is rather small, but for local huts it might occasionally be used where other timber is scarce, as in the dry zone. It makes a fair firewood in those places. Although the fruit is supposed to be edible, very few natives have tried it, and apparently it is only used in times of great scarcity.

Pterocarpus Osun. African Padouk or Barwood. Osun, Osun dudu (Yoruba); Ume, Ureben (Benin); Opepe (Ikala, Ijor).

It is found in the Ogoja and Calabar provinces of Nigeria, in the mixed deciduous forest zone, where it is none too prevalent. A specimen was found near Ibami, in the Obubra district. It is a small tree with small yellow flowers and rather small leaves. The branches are placed close together and the crown is very dark and thick. The bole is short, rarely exceeding 15 feet in length, and the bark a dark brown colour. The bole reaches a girth of about 5 feet.

The sapwood is white and the heartwood of a dull-red colour, but in proportion the sapwood is rather wide. It is moderately hard, fairly durable, but not termite-proof. It planes well, saws easily, takes nails; it does not split very well.

It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration does not appear to be very good. It is doubtful if it sprouts from the stump. It has not been cut for export, nor has it been felled for local use.

On the Cross River the Camwood was sold to the European merchants, at the rate of 409 billets per ton, for £4 10s., so that with the added cost of river and ocean freight and sale charges, there was no profit when it was being sold at £6 10s. per ton in the Liverpool market. Better prices are always secured if it is shipped in squared logs, 24 inches square and 24 to 30 feet in length.

Apparently it is not the Camwood used by the natives, because plenty of trees are seen scattered about in the neighbourhood of Obubra untouched.

Pterocarpus erinaceus. African Rosewood. Apepe, Ara (Yoruba); Oyo, Upeka (Benin).

This tree grows in the dry-zone savannah forests of the Ogoja province of Nigeria. It is of small size; the flowers, which are yellow, appear in March. The timber is of little value, the tree not being large enough to yield a useful timber, but it has been sold as African Rosewood. It has a beautiful rose-red colour.

Pterocarpus sp. So-called Camwood. Osun pupa (Yoruba); Akume (Benin); also spineless fruited Camwood.

It is found in the Calabar, Ogoja, Benin and Ondo provinces of Nigeria. On the bank of the Cross River, near the Ossizza factory, there is a large specimen, standing about 20 feet away from the water’s edge.

It is not very common, and chiefly found near river banks in the evergreen forest towards their northern limit. It is a medium-sized tree, reaching a girth of 9 feet at the most and a height of 70 feet. The bole length does not exceed 40 feet. The bark is light-brown, almost yellow-brown, with rough fissures and fibrous surface, more like an elm, though thinner. The branches are thin and light-coloured. In flower the tree is a mass of little yellow peaflowers, and numerous bees swarm round the crown of the tree, indicating its presence. Again, when the fruit ripens the crown is a mass of yellow-brown winged fruits all fluttering in the wind. They are always in bunches near the ends of the twigs. The fruit is round and flat, with no hairs on it, with a thin papery wing completely surrounding and joined to it, which makes it rather thicker and stiffer than the other species. It is not at all typical of the Pterocarpus genus. The seed in the centre has a rough surface. The trunk usually is not quite straight, having a slight bend or two in its length. In habit, more like a Combretum or young elm to look at. The crown is round, almost spherical, and does not usually occupy more than one-third of the height of the tree.

The sapwood is white; the heartwood is of a dull purply colour, which is inclined to stain into the sapwood after the tree is cut down and exposed to rain. On the whole the colour of the wood is deeper than that of the other Pterocarpus, but it is said to yield a less fast and poorer coloured red dye than that of the other species, P. Osun. It is moderately hard. It planes well, and is sometimes cross-grained. It takes nails easily, but does not split very well, though it saws with comparative ease.

Although it stands a good deal of shade in its youth, it is apparently a light-demanding tree with soil-protecting and soil-improving qualities. It is not very fast-growing. Natural regeneration appears to be poor, chiefly, perhaps, owing to the fact that the seeds are quickly eaten by small boring insects soon after they fall to the ground. It is rather exacting as to soil, and prefers the deep, moist, sandy loam. Only isolated specimens are seen.

The timber has not been exported yet, and despite the fact that it does not reach such a large size as P. Osun, it deserves a trial. For local use it should find a place for house construction in a similar position to which the Osun and others are used by the natives.

It has not been cut or used as a dye root, chiefly owing to its poorer colour. It is, however, used in house-building.

Pterocarpus. Cross River Camwood.

It is found in the Obubra district of the Calabar province of Nigeria. In habit it is very similar to the other Camwoods.

Pterocarpus Soyauxii. Large Fruited Camwood. Arakpa, Ume (Benin); Ukpa (Efik).

It is found in the Ogoja, Benin, Warri (?), Ondo, Ibadan (?) and Abeokuta (?) provinces of Nigeria.

It is a common tree in the mixed deciduous forests, reaching a height of 80 to 100 feet, with a bole length of 50 feet and a girth of 10 feet. The bark is a darker colour than P. Osun, but a little rougher. The leaf is smaller than P. Osun, but is unarmed. The most typical difference in this tree is the fruit, which is the largest of all, 2½ to 3 inches in diameter, with plenty of prickly thorns in the centre of each surface. The wood is a much darker red, quite a dull, almost purple red. The root spurns on the whole extend higher up the trunk than P. Osun (up to 4 feet). The slash is white, but thin red latex soon exudes out of it.

The wood is hardish, but the sapwood is very white and soft. The wood does not make the same kind of stain as P. Osun, though apparently it keeps its colour much better than P. Osun. When exposed to light, P. Osun loses it very quickly and becomes a dull-brown colour. The grain is open and varies a little in colour, giving it a pleasing effect. Termites do not attack it. It splits well.

It sprouts from the stump slightly, but such shoots do not attain any size. Seedlings come up readily from fallen seeds. The seeds are liable to be eaten by the “ground pig” almost at once. It grows moderately quickly, but is a light-lover. It has an undivided stem.

Samples were sent to Liverpool in 1916 and sold as African Padauk, and it was reported that “small quantities sell” satisfactorily. It has been cut for local use for buildings.

Native Use.—It is used for making wooden shovels, all out of one piece. Also in house-building as wall-plates at the top of the mud walls, also in the Oba’s house for uprights.

Erythrophlœum sp. Sasswood. Inyi (Benin).

This tree was determined from material from the Central Circle.

Erythrophlœum Guineense. Sasswood, or Sassy Bark, or Ordeal Bark. Erun obo (Yoruba); Oginyi (Benin); Akpa Etuidiwi (Efik); Arachi (Ibo, Asaba); Inyi, Ibo (Onitsha, Ibo, Owerri).

It is found in the Ibadan, Abeokuta, Ondo, Benin, Onitsha and Ogoja provinces of Nigeria in the mixed deciduous forest zone, where it is often very prevalent, more especially north of Ifon and Alabeta in the Benin province.

It is a large tree, reaching a girth of over 10 feet and a bole length of over 30 feet. The crown, however, is large and wide-spreading, but generally spherical in shape. Comparatively low down, the bole divides up into three or four main limbs. The trunk is seldom very straight, usually having a twist in one direction or another. The root spurns are moderately large, but are rounded in shape. The bark is dark-brown and thick, scaling off to a slight extent in old age. The fruit is a pod about 3 inches long and an inch wide, containing six or eight flattish black beans, black to brown. These burst when ripe, but the seeds only gradually fall to the ground. The fine pinnate leaves are close together and open out into dense foliage most typical of the Leguminoseæ. The upper part of the limbs and trunk is light-brown. The flowers are minute and not often seen.

The sapwood is dull yellow and the heartwood a dull red-brown. It is very heavy and hard, but not as hard as red ironwood or the Yoruba ironwood. It is very durable and quite termite-proof; although sometimes a little cross-grained, with good tools it can be worked up to a smooth finish by planing. Holes have to be made in it for nails. It saws well, but splits only moderately easily. In the saw mill it was found that the hardness of the wood blunted the saws, which needed constantly sharpening.

It is a slow-growing, shade-bearing, soil-protecting, soil-improving tree. Natural regeneration appears to be good, and it is moderately resistant to fire. Tends to condense dew in the dry season. It suppresses most other trees by shade. Amongst the dry-zone vegetation it clings to the banks of rivers, and is common on the upper banks of the upper reaches of the Ogun. No plantations have been made with this tree.

In 1906 sample logs of the sister tree, E. micranthum, were exported and sold in the Liverpool market as a species of oak, so that this timber deserves a trial as a substitute for teak or oak.

It was cut for the Public Works Department at Onitsha and found very suitable for decking of bridges. The small bridge over the Nkissi, near Onitsha, was built entirely with this timber.

Erythrophlœum micranthum. Sasswood or Ordeal Bark. Ovinni (Benin); Erinji (Ijor); Ihi (Ibo, Owerri).

It is found in the Warri, Benin and Calabar provinces of Nigeria.

As a small tree, one of the first to appear when the mangrove swamp gives way to the evergreen rain forest near the coast. On solid land it attains a large size, even larger than that of E. Guineense. The pod is a little larger than that of E. Guineense, and the bark smoother. The crown is dense and very large, almost spherical in shape, and reaching more than one-third down the length of the tree.

The timber is very similar in its qualities to E. Guineense, but has a straighter grain in the larger specimens. It is very durable.

It is a slow-growing, shade-bearing tree, with soil-protecting and soil-improving qualities. Natural regeneration does not appear to be very good, though numerous pods are borne on the tree almost every year. No plantations have yet been made with it.

For local use, it has not been cut in a similar way to E. Guineense. The natives occasionally use this tree for making canoes. In the 1906 timber report from the Liverpool market it was valued as a species of oak at 1s. 9d. per cubic foot, and was not considered so good as either red oak, Lophira procera, or white oak, Ostryoderris impressa.

Native Use.—The bark is boiled in water and a beautiful red-coloured liquid is produced. It is administered as an ordeal trial for witchcraft, and is not poisonous if given in large doses.

Brachystegia spicæformis. Agberigeddi, Ako (Yoruba); Okkwan (Benin); Etare (Oban, Ekoi); Ungu (Ibo, Owerri); Mpanju, Akpanya, Ikpanya (Efik).

This tree is found in the Abeokuta, Ibadan (?), Ondo, Benin, Warri, Owerri, Calabar and Ogoja provinces of Nigeria.

It is a rough, scaly-barked tree of huge size (see illustration), reaching a girth of 30 feet and a height of 150 feet. The crown is flattish, formed by a few wide-spreading limbs and numerous small branches. The foliage is moderate for a Leguminous tree. The yellowish flowers are almost unseen, being placed underneath the leaves. The dark-brown woody pods burst with a bang not unlike a gunshot, and release four or five flat black, shiny beans about ½ inch across. The foliage goes almost black on reaching the ground, killing all the small plants. A brownish gum exudes from the tree when cut, and this hardens into a reddish, opaque mass similar to Almeidina, and in fact is the source of this gutta percha-like substance.

Timber.—It is a rather hard, light-brown wood with pretty, almost evenly distributed streaks of darker brown shade in it. It is very durable. The white sapwood soon rots on exposure to the weather. It is suitable as a furniture wood.

Silvicultural Characteristics.—It bears a good deal of shade. It reproduces almost every year plentiful mature seed; grows fast, but not so rapidly as the cotton-tree, Ricinodendron and others. It is sometimes distinctly gregarious, as, for instance, south-west of Benin City.

European Use.—It has not been exported, but the P.W.D. have used it for verandah-posts and planks. It has been much admired for the good colour of the wood and the streaky grain.

Native Use.—By the Benin people it is not considered a good wood, but the gum is sometimes used.

Daniellia ogea. Gum Copal. Ogea (Yoruba); Ogea (Benin); Udeni (Ibo, Owerri); Mpanju, Ikpanya, Akpanya (Efik). Also known as D. oblonga and Cyanothyrsus ogea, but now called D. ogea.

This tree is found growing in the heavy-rain intermediary forest of Benin, Ondo country and Mamu Reserve. It is a very fine tree with straight rounded bole, often reaching a height of 120 feet before the first branch. The bark is light grey and slightly ringed. The flowers blue and not very noticeable.

Timber.—Of no commercial value, as it is soft and rots quickly.

Uses.—A good gum copal is obtained from it, the best in the ground, after the tree has rotted. It is used for varnish making; worth 30s. to 60s. a hundredweight.

Daniellia Fosteri. Gum Copal. Oguja or Ogea (Yoruba).

Found near Olokemeji and Ijebu-Ode. It yields a third-quality resin according to Holland in The Useful Plants of Nigeria.

Daniellia Punchii (Kew). Gum Copal. Ajia (Yoruba).

Daniellia caudata. Benin Gum Copal. Mogbara, Ashuwole (Yoruba); Ogea (Benin); Agbara (Ikale.)

It is found in the Ondo, Benin and Ogoja provinces of Nigeria. The bole is the straightest and most cylindrical of any of the African forest trees. It often attains a height of over 100 feet before the first branches are reached. The cylindrical shape is further enhanced by the few quite concentric rings on the bark, horizontally arranged round the trunk of the tree. The bark is otherwise quite smooth and of a silvery-green or light-green colour; for the size of the tree it is very thin, and the tree may reach a girth of 25 feet, and the bark then is usually only ½ to ¾ inch thick. The slash is yellowish-white; the sapwood is white and scarcely distinguishable from the heartwood, which gradually takes a pinkish tinge when it is dry. The flowers are blue and not unlike those of the fuchsia, and the tree is easily seen at the end of the dry season by the bare crown with its blue flowers. The path later on is covered with these. There are practically no root spurns, the stem emerging straight away from the ground. The crown is very flat, and does not usually occupy more than one-fifth of the total height of the tree. The branches are few and of slight and almost feathery build. The timber is soft, not durable nor termite-proof. It saws easily, does not split very well, and considering its softness it does not plane at all well nor with a very smooth surface. Natural reproduction by seed appears to be poor, although plenty of seeds seem to ripen; there is one seed in each pod. It is a light-loving, deciduous tree, but for eleven months of the year it is certainly a soil-protecting and soil-improving tree. It demands a deep, moist and somewhat rich soil, though judging by the various localities in which it is found it is doubtful if it is really exacting as to soil.

In 1906 sample logs of this timber were sent to the Liverpool market and considered to be a species of mahogany, but of no value. Natives have not used it to any extent for local purposes.

Piptadenia Africana. Light African Greenheart. Agboin (Yoruba); Sanga (New Calabar); Iteruku (Efik); Ebbome (Oban, Ekoi); Ekhimi (Benin).

This is a common tree in the Abeokuta, Ondo, Benin, Warri, Owerri, Onitsha, Calabar and Ogoja provinces of Nigeria. It is one of the most prevalent trees in the evergreen forests, but is also found in the mixed deciduous forests, especially, in both cases, near the edges of the waterways. It is a very large tree, attaining a height of over 120 feet and a girth of over 12 feet. The bole is often 80 or 90 feet in length and perfectly straight. The crown is thin, ovally flat, but wide-spreading. The thick, heavily foliaged and drooping appearance at the ends of the branches makes the tree a most handsome ornament to a station. At the root, flanges are comparatively long and widespreading, reaching often over 6 feet up the stem, having root spurns quite 12 or 15 feet away from the tree. The stem divides up into a few large branches which form the crown; the bark is yellow-brown and smooth, but when the tree is growing in the sunlight it becomes a much lighter colour and sometimes almost grey. The slash is yellow, with a light-brown tinge; the flowers are quite inconspicuous when they appear in January or February, being formed of little narrow spikes. One of the most conspicuous features of this tree is the thin, flat pod, which may grow as much as 1 foot long and nearly 1 inch broad. Six to eight seeds are contained in each pod, and these, including the wing, are 2 inches in length. The flat seed, which is found in the centre, is brown and shiny, and is only about one-sixteenth to one-eighth of an inch in thickness. It has a tiny string-like attachment to the centre, which distinguishes it from Newtonia on the one hand and Cylicodiscus on the other. The young green foliage is also most distinctive and attractive in its freshly salmon-pink colour, also the greenish tips of the older leaves. The leaves themselves are bipinnate; there are often twenty to twenty-four pairs of pinnæ, each of which is about half an inch long.

The sapwood is white and comparatively wide; the heartwood is a pretty light-brown colour, a little darker when fresh, but still retaining a good light-brown colour when it is dry. Although at first rather heavy and hard, it seasons as a comparatively light and scarcely hard wood; it planes well and saws fairly easily; takes nails moderately well, but does not split at all easily, especially when fresh; has an open grain and the pores are comparatively long. It is a durable wood and is almost termite-proof, especially when it is quite dry. When moderately dry the logs float in water. It weighs 53 pounds per cubic foot.

It is a light-loving species which does not protect or improve the soil, except in so far as it is a leguminous tree and its roots thus improve the ground. It is a moderately rapidly growing tree which stands a little shade in its youth. Natural regeneration appears to be only moderate. It sprouts well from the stump, and stump shoots appear to be very persistent. It is rather sensitive to fire and is easily killed by placing rubbish near its roots and then burning the heap. No plantations have yet been formed for this tree. In the forest the seeds fall to the ground and are soon eaten by a small boring insect. It likes a comparatively good soil, but is found on sandy soil which has great moisture; it does not like flooding, but will stand a little.

Locally, it is occasionally used as a house-building timber. The bark is occasionally chipped off for use medicinally. Europeans have cut it up and used it as verandah-posts, joists and verandah handrails. However, in an unseasoned state the sapwood was attacked by termites, and thus it was not entirely satisfactory. The heartwood when quite dry does not warp and appears to be very durable.

In 1906 sample logs of this timber were sold in the Liverpool market as “Greenheart” at 2s. 9d. per cubic foot. Since that date no regular supplies have been sent to the market, so that it has not been thoroughly tested as to its value as an export timber.

Isoberlinia Doka (Kew).

It is found in the Ogoja, Abeokuta and Owerri provinces of Nigeria.

It is a medium-sized tree with rather large, widespreading pinnate leaves. It is one of the few trees that are gregarious in habit, groups from half an acre to an acre in extent being found. The tree is used for house-building and withstands a certain amount of fire, as it grows at the edge of the dry-zone forest.

Berlinia acuminata. Red Oak. Apado (Abeokuta), Ewon Pala (Ikale), Adugbin (Ibadan) (Yoruba); Ekpagoi (Benin); Ajia (Ibo, Asaba); Obuba (New Calabar); Hanabali (Oban, Ekoi).

This is a common tree in all the Southern Provinces of Nigeria. Although it is found most frequently in the evergreen forest zone, a small, bush-like variety is also found in the open deciduous forest. The most conspicuous features of this tree are the large foot-shaped unripe pods; these stick out, isolated, at right angles to the general direction of the surface of the ground—this makes them appear all the more prominent and most odd in appearance. When the pods burst, the large flat beans are released, and each side of the pod curls up, but appears speckled white with round dull spots along the middle. The flowers are white, nearly 2 inches across, with one red streak in the centre. In the evergreen forest zone these flowers do not seem so conspicuous, but in the dry zone the tree is covered with blossom, making it one of the most beautiful. In the heavy forest zone the bole reaches the length of nearly 80 feet and the girth of over 20. With its smooth, shiny grey bark, at the first glance it is not unlike a beech-tree. The root spurns are usually quite small, and do not extend beyond 2 feet up the stem. The slash is white and of a yellow colour on the inner edge. The leaves are pinnate, with one odd leaf at the end, being usually nearly 3 inches long; the total length of the leaf is often over 1 foot. The freshly ripened beans are almost square in shape, flat, and nearly a quarter of an inch thick. Each side of the pod is usually the size of an average man’s foot, and sometimes larger; it is also not unlike it in shape, but the curve where the instep should be is very slight. The crown is spherical and very large, often occupying one-third of the total height of the tree. The foliage is comparatively dense, and it is not possible to see through the top of it. The tree loses its leaves for a very short time each year. In the dry zone it is often not much more than a shrub, or at most a small tree 35 feet in height.

The sapwood is white and wide. The heartwood is of a deep-red colour, especially when freshly cut; when dry it still retains a good red colour, and from this feature it has been termed “red” oak. The timber saws fairly well, but splits badly; it is somewhat hard to plane it up to a smooth surface, as it is sometimes cross-grained. The heartwood is termite-proof; it takes nails only moderately well. It is a moderately hard and durable wood; it does not warp very much. When the logs are dry they will float in water. The weight of the timber is 55 pounds per cubic foot.

Considering the prevalence of the tree, natural regeneration is poor—rodents may account, of course, for many of the beans; it sprouts well from the stump. In the dry-zone forest region root suckers appear too. It is a shade-bearing and soil-improving tree; it does not grow very fast. No plantations have yet been made with this tree, though it deserves a place in experimental plantations. It demands a good soil, and the roots go down to a greater depth than many of the other trees.

Locally it is used as a house-building timber, and occasionally the dried pods are used as firewood.

In 1906 sample logs of this tree were sold in the Liverpool market as red oak at 2s. per cubic foot. It was not considered as good as Aligna or as Erumacie. Since that date no further shipments of this timber have been made. A further testing of the market by small trial shipments of logs would thoroughly reveal its value as an export timber.

Berlinia auriculata (Benth.). Red Oak. Ekpagoize (Benin).

Found near the Okwo River in the Siluko sub-district of the Benin province. It is not quite such a large species as the B. acuminata.

Parkia biglobosa. African Locust. Aridan Abatta, Irugbo Abatta Iru (Yoruba); Ubgori, Lakobemi, Enymi (Benin); Inya (New Calabar); Ekok (Oban, Ekoi).

It is a very common tree in the Calabar, Owerri, Warri, Benin, Ondo (?) and Abeokuta provinces of Nigeria.

It is a large tree, with wide spreading fruit flanges. It has darker and heavier foliage and a wider crown than Parkia filicoidea. It often shows up on river banks with its light-red young leaves. It should be easily distinguished from other similar trees of this family by its cluster of beans, similar to French beans, when ripe. These are yellow, and the spice-like scent and the round balls of staminate flowers of a crushed strawberry colour are not easily forgotten. Often only the yellow pistil is found lying on the path. It likes a damp to wet soil, and is usually found growing at the edge of, or actually in, freshwater swamps.

Timber.—The wood is hardish, but is said to rot easily, though it appears to be rather doubtful, and probably only applies to unseasoned wood.

Natural regeneration by seed is good. The tree stands a good deal of shade in its younger stages of growth. No other trees will grow under it, and few can stand any or much of its shade.

European Use.—It has not so far been used by Europeans for export or local use.

Native Use.—The seeds are cooked and eaten to some extent by the Yorubas and Benin people.

Parkia filicoidea. African Locust. Irugba (Yoruba name for fruit); Igba the tree (Yoruba); Gumui (Mendi); Olibracha (Egba) (Yoruba).

This is a common tree in Abeokuta, Oyo, Benin, and Ogoja provinces of Nigeria. It is found in the deciduous forests. It reaches a height of over 60 feet, with a girth of 5 feet. One of the most distinguishing features of this tree are the very feathery leaves, which appear after the flowers. The large spherical balls of the red staminate flowers enliven the tree in the early part of the year; later in the year masses of pods, each about 9 inches long, hang down from the ends of the twigs. The base of the bole is often gnarled, partly with the slight root flanges and by the almost continual cutting of the bark by the natives. Normally the bark is brown and comparatively smooth. The bole is short, dividing about 20 feet from the ground into a large number of small branches. On the whole, as the tree advances in age the branches tend to become pendulous. The crown, spherical in shape, is inclined to be irregularly broken up—partly by the different length of the branches.

The sapwood is white and the heartwood a dull-brown colour; for the size of the tree the sapwood is wide. It saws indifferently well, splits badly; it is hard to plane; it is said to be termite-proof. The wood is hard and tough.

The tree is a light-loving but not soil-improving species, except in so far as the root globules take up nitrogen and free it for the use of other plants. Naturally, generation is none too good. Root suckers appear to some extent; it sprouts most readily from the stump. Perhaps the lack of young self-sown seedlings is due to the fact that the seeds are largely used by the natives. In a few places small plantations have been made with this tree. It is very fire-resisting, and apparently the fruit-bearing capacity of the tree is not reduced to any extent by the prevalence of the annual grass-fires in the localities where it is found. During the whole of its life it is a slow-growing tree.

The yellow pulp in the pods is eaten by the natives. The bark at the base of the tree is chipped off and used for making a tonic when infused with water. The tree is occasionally used locally as a house-building timber; for this purpose it is used chiefly as uprights in the main buildings.

The timber has not been tried for export, and it is doubtful whether its size warrants its use for this purpose.

Tetrapleura Thonningii. Angular Pod. Aridan (Yoruba); Igmikkia (fruit), Ikhememi (tree) (Benin); Osshosha (Ibo, Asaba).

The dark-green feathery foliage on its oval crown is very typical of this tree, especially when it is found near a roadside in the mixed forests. It is also often found on river banks at the edge of the dry zone or in other parts of the mixed forests. The indehiscent pods with four edges, leaving practically no centre, are most typical of the tree; they are shiny and have a peculiar medicinal smell. The fruit is known as Igmikkia, by which name the tree is most usually called by Europeans, in the Benin country.

The tree is prevalent in the Abeokuta, Ondo, Oyo, Benin, Onitsha, Owerri, Calabar and Ogoja provinces of Nigeria.

It is a shade-bearer and thoroughly protects the ground all the year round, except for about two weeks when the leaves fall. Natural regeneration does not appear to be good, seedlings being rarely found, and no plantations have been made with it, though if of more value it might be mixed with teak. The seeds always command a ready sale at a low price.

The wood is hard, brown, and splits badly. No use has yet been found for it. It is sometimes cross-grained, the sapwood white.

The natives use the timber for making doors, window-frames and benches. The seeds are sold in the Yoruba, Benin and Ibo markets; they are cooked for soup, which acts as a slight aperient or is of other medicinal value.

Millettia Thonningii (Baker). Ito (Yoruba); Ebakwe (Benin).

It is found in the Benin and Abeokuta provinces of Nigeria. It is a small tree really, reaching a girth of only 4 feet, with a short bole and a few somewhat slender and drooping branches. The twigs and new leaves are distinctly of weeping habit. In February, in the mixed forest, the bare tree shows up with its beautiful clusters of lilac-coloured, pea-shaped flowers, and later in delicate contrast to the fresh, light-green leaves. The trunk is usually not quite straight, being bent about 8 or 10 feet from the ground. The bark is smooth, thin, and almost of a silvery-grey colour. The branches are very whippy and difficult to break.

Timber.—The wide sapwood is white and the narrow heartwood green-brown when freshly cut. It is very hard, of fine grain and texture, and planes with a smooth surface. It does not split; is very rough and flexible.

It is a shade-bearer and grows slowly. The fruit is a small black and pointed pod which opens when ripe, having about three or four beans inside. It is easily killed by fire, but sprouts freely from the stool. It does not crack nor warp.

It has not been exported nor cut for local use, but it should be a good wood for turnery.

Native Use.—It is used for knives and axe-handles.

Cynometra Afzelii. Waterside Cynometra. Akushunmajadin, Alade (Ikale); Iku (seeds), Aka, Eggi (Yoruba); Ogabezzi, Ogikiomi Upakeka (Benin).

It is a common tree in the Benin province of Nigeria. On the whole it is smaller than C. Mannii, though it has a similar habit. It grows, too, in similar localities, though for the most part it is confined to the evergreen forest zone. It also grows more or less in gregarious groups. The shade of this species is just as dense, if not denser than that of the foregoing. The leaf of the Cynometra is distinguishable from most other leaves because the mid-rib of it is placed towards the inner or almost straight-sided edge of the leaf. In fact, if two leaves are held closely together, they almost look as if they were one which had been cut in half. Benin natives have no use for this tree except as firewood.

Cynometra Mannii. Waterside Cynometra. Ekkun (Yoruba).

It is a common tree on the banks of streams in the Ibadan and Abeokuta provinces of Nigeria. One of the most characteristic features of this tree is the pinkish-red colour of the fresh leaves, hanging at the ends of the drooping branches. In November each year the large, corrugated, single bean in each almost indehiscent pod is another curious feature of this tree. The trunk is usually short—in fact, often divided into three or four separate stems, almost at the base. Narrow fringes consisting almost entirely of this species are found on river banks. The dense shade cast by this tree prevents any other species from growing underneath. The timber is hard and difficult to split, and apparently it is not attacked by white ants. The tree is a shade-bearer. Natural reproduction from the seed is good, it being distributed often by water. It also sprouts from the stump. A few root shoots also appear. The tree has not been cut for local use nor has it been used for export. The natives use the wood for making posts and doors.

Cylicodiscus Gabunensis. African Greenheart. Osho, Aja, Iji (Il.), Ajaigi (Yoruba); Okan (Benin).

Distribution.—In the Abeokuta, Ondo, Benin, Warri, Owerri, Calabar provinces of Nigeria.

Chief Characteristics.—It is a very large tree of the evergreen forest zone, attaining a height of 200 feet and a girth of 30 feet. It is armed in its earlier growth up to the pole stage, when all the brown thorns disappear. Its long, brown pods, up to 3 feet long and 1½ inches wide, opening from one side only, with their long, thin, papery seeds, are most typical of the tree.

Compared to its size the bark is thin, and in old age it is inclined to scale off in small pieces. In the distance it looks practically smooth. This is one of the most gigantic and impressive trees of the forest, with its enormous bole stretching cylindrically up amongst and over the other trees, with a large, widespreading, somewhat flatly shaped spherical crown. The leaves are pinnate, with three of four pairs of little ovate pinnæ, with one odd one at the end. The flowers are minute, forming little, thin, knitting-needle-thick spikes of yellow bloom. These last only a few days, and only once in thirteen years have I seen the flower. The tree and pod are unmistakable, even when it is a large one. The numerous brown pods hang down amongst the foliage and appear to be much longer than those of any other Leguminous tree. This feature alone distinguishes it from any similar species. The bole divides up into a few large limbs and many small branches, making the foliage lighter and thinner than many other Leguminous trees, but not so thin as that of Piptadenia Africana. The root spurns are very slight and rounded, merging into the bole of the tree 1 foot to 3 feet above the surface of the ground. At the base of the bole the bark is sometimes cut off by the natives for “Ju-ju” purposes, and then an additional swelling appears there.

The sapwood is white and narrow, the heartwood greenish-brown when fresh, and yellowish-brown after it has lain in the forest for a few years. It is very hard—in fact, one of the very hardest of African timbers. Under cover it is very durable. In the open it does not last so long. It is termite-proof. The sapwood, however, rots in the open, and the heartwood softens very considerably. It is somewhat fibrous, but it planes up well, with a smooth surface. It does not take nails, saws well, and splits moderately well. It has considerable elasticity. It makes a very hot-burning firewood, but is inclined to crackle and make sparks.

It is a moderately fast-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration appears to be fair, but the seeds are often eaten by little boring insects, soon after they fall to the ground. It appears to be rather exacting as to soil, liking a deep, moist loam sand with good drainage. It is scarcely a fire-resisting tree, but very storm firm—in fact, one of the safest trees.

In 1906 sample logs of this tree were sold in the Liverpool market as African Greenheart at 1s. 8d. per cubic foot, and were stated to be good greenheart. Since then none has been cut or shipped to England. With the exception of its use for verandah-posts for a public building in Benin city, it has not been cut or sawn up in planks for local use. Considering the comparatively large quantity available, it deserves a fair trial both for export and local use, more especially for heavy constructional work, such as bridges, piles, uprights.

Amongst the Benis it is sometimes a “Ju-ju” tree, and is said to impart strength.

Leptoderris.

Owerri province of Nigeria. It is a medium-sized tree found growing near the Imo River, but not very common. It has a hard wood.

Baphia nitida (Afz.). Awenu or Irosun. Borri Borri (Yoruba); Otwa (Benin); Ubara (Efik).

Is a small tree, which is usually found near villages, being left by the natives when land is cleared. The white flowers are almost of pea shape. It has a small leaf, and does not usually get any larger than about four inches in diameter.

It is found in the Ondo, Abeokuta, Benin and Calabar provinces of Nigeria.

The real Camwood of commerce.

It is very slow-growing, and is not a hard wood, with dark-red heartwood of small size in proportion to the size of tree. It forms late, too. If the stem is wounded, even the sapwood becomes a rich red colour like the heartwood.

The probable origin of the word “Camwood” is taken from the Timani name, Cam, of the Baphia nitida tree in Sierra Leone. From another point of view this is all the more interesting, as the original exports of Camwood were made from Sierra Leone in the early part of the nineteenth century, and this name “Cam” brings together the tree from which the Camwood is obtained and the tree botanically known as Baphia nitida.

Native Use.—A piece of the wood and a leaf are placed on the ground where a woman has borne a child, whether it be on a road or in the house. Not used in Benin as a dyewood.

Baphia polygalacea. Walking-stick Camwood. Asana, Ossusu (Yoruba); Aswen (Benin); Mbomokuku (Efik).

It is found in the Abeokuta, Benin and Calabar provinces of Nigeria.

A small tree of typical Baphia habit, which is common in parts of the Benin district of the same named province. It has considerable elasticity, though it dries rather hard and does not give much in that state. It is a rather slow-growing tree, which lights the shade of the forest, and is also a soil-protecting and soil-improving tree. Natural regeneration appears to be good in several places. It sprouts slightly from the stump, when felled. No plantations have yet been made with this tree. The walking-sticks have not been exported to England for trial in the market.

The curiously shaped single root, sticking out almost at right angles to the stem, makes a good walking-stick; it is curved as well slightly, too. When the bark is peeled off and the stem partially charred, it looks very effective.

Baphia pubescens. Benin Camwood. Awewi (Lagos) (Yoruba); Ositwa (Benin).

It is a small tree, 30 feet high and 3 feet in girth, with usually half the bole sapwood white, and dark-red heartwood, which is hard and close-grained. The flowers are white, with yellow tips to the two petals. It is often seen just outside villages, or where two paths meet.

Native Use.—It is not used for dye, though apparently the wood is just as suitable as B. nitida.

Baphia sp. Camwood. Mogbara (Yoruba, Ikale); Owe, Aswen (Benin).

It has also been determined as Carpolobia lutea, and as one of the Oleaceæ.

It is a shrub with a stem of about 4 feet in height. The fruit is a small nut containing three small kernels. The wood is very hard.

Native Use.—The seeds are eaten.

Macrolobium palisoti. Ogaba (Benin); Nya (Efik).

It is a common tree of the Abeokuta, Ibadan, Ondo, Warri, Benin, Owarri and Calabar provinces of Nigeria. It only reaches a girth of about 2 feet and a height of 20 feet. The leaf has two pairs of pinnæ, with one end leaflet. The small pod containing two or three flat seeds is most typical of this tree; the seeds are ¾ inch in diameter and of a dark-brown colour; the flowers are white; the timber is cross-grained and rather hard; the sapwood is white and the heartwood of a dark brown. The tree is a shade-bearer, soil-protecting and improving. It is usually found amongst the undergrowth in the thicker parts of the evergreen forest zone. Natural regeneration is usually good. The wood is used locally in the Yoruba and Benin country for posts; it has not been sawn up for planks, nor has it been exported to England.

Macrolobium stipulaceæ.

It was stated it was found in the Calabar province.

Nr. Macrolobium sp. Ogabeszi (Benin).

It is found in the Benin province of Nigeria. It is a small tree of the evergreen forest zone. The foliage is very dense. The tree has a short bole of about 15 feet, and the crown is much branched; the pod is rather larger than Macrolobium palisoti. According to the natives, this is the “Ogaba” of the waterside. The timber has not been exported to Europe, nor do the natives use this somewhat hard wood to any extent.

Dialium Guineense. Pulley Wood, Velvet Tamarind. Awin (Ib.) (Yoruba); Ohiorme (Benin); Amoyin (Egba).

It is found in the Ibadan, Abeokuta, Benin, Calabar and Ogoja provinces of Nigeria. In the mixed deciduous forests it is very prevalent in certain localities. Of medium size, it rarely exceeds a girth of 5 feet. Where found, it often comprises over 10 per cent. of the standing stock of the forest.

The wood is used for small boats in Senegal. It exudes a red-coloured sap in small quantities.

The fruit, with its flat and round, velvety little pods, is most typical of this tree. These are of a very dark chocolate colour, and in the distance appear almost black. The bole is usually silver-grey. The slash is light-red, and the reddish, latex-like substance exudes when the bark is cut. The crown is dense and compressed, being mainly made up of a number of small branches. In proportion the leaves are small and make a very dense foliage. The rusty-red slashing marks, or other marks caused by damage to the trunk of the tree, show up most distinctively, especially against the grey surface of the cortex, are one of the most distinguishing features of this tree.

The sapwood is white, the heartwood is dull-red, rather larger in proportion than we should suspect, compared with the size of the tree. It is hard and tough, and does not split well. It planes up, however, with a smooth surface, is very durable and termite-proof. It does not take nails well, but saws fairly easily.

It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration appears to be good. It appears to be a little exacting in regard to soil. It is slightly fire-resisting, chiefly, perhaps, owing to the fact that few weeds or grass grow in its shade. No plantations have been made of this tree. It bears a good crop of fruit almost every year.

It has not been felled for export, nor has the timber been sawn up for local use. It was formerly used in the Congo for pulley-blocks, for which purpose it is said to be admirably suited. Amongst the natives it is sometimes used for house-building.

Nr. Newtonia. Boji Albizzia or Giant Pod.

It is rather an uncommon tree of the Boji Hills forest; the enormous flat, papery pod makes it easily distinguishable from any other tree.

The pod is about 15 inches long and 9 inches wide, with a slight depression in the middle of one side.

Pithycolobium altissimum. Bent Pod or Gambia Pod.

It is a medium-sized tree, found at the edge of swamps near the sea coast in the evergreen forest zone. It appears to stand a waterlogged soil.

The pods are used for tanning hides and making ink (Moloney). It has curious semicircular pods, which are typical of the tree, containing eight to ten seeds.

Afzelia sp. Waterside Ekpagoize. Ekpagoize (Benin).

It is found in the Benin province of Nigeria. It is a medium-sized tree, reaching a girth of 7 feet and a bole length of 40 feet.

This tree has often been confused botanically with Berlinia acuminata, but it is undoubtedly an Afzelia. The flowers are of a reddish colour and very pretty; the foliage is not quite so heavy as that of the other Afzelias; the pod is rather smaller than that of either Afzelia Africana or Afzelia cuanzensis. The wood is a reddish-brown colour, a little cross-grained, but more durable than the other Afzelias. It does not split well, and can only be planed with difficulty; the grain is very coarse and fibrous. Samples of this timber have been shipped to England and sold as red oak. The natives scarcely ever use the wood, partly because the tree is not very prevalent.

Afzelia cuanzensis. Bilinga, Red-arilled Afzelia. Aiyo (Yoruba); Aligna (Benin); Igbin (Brass); Onuru, Oshoshi (Ibo, Owerri); Mbarakun (Oban, Ekoi).

It is found in the Benin, Ondo, Abeokuta, Calabar, Owerri and Ogoja provinces of Nigeria.

It is a medium-sized tree, with a pod, which is usually slightly crumpled or bent, containing about six or eight black nuts, with a red aril at the base, and each nut is pointed more, and less rounded, than in A. Africana. On the whole it is found more in the deciduous mixed forest than on the edge or in the dry-zone forest region, where A. Africana abounds. The bark does not scale oft so much as that of A. Africana. It stands more shade than A. Africana. It does not reach such large dimensions, though logs up to 18 inches square and 24 feet in length could be obtained.

Up to the present the tree has not been cut to the same extent as A. Africana, though the wood is very similar and apparently just as durable.

No separate report has been made on the timber as to its value in the European markets.

Afzelia bella. Calabar Afzelia. Aligna (Benin).

It is found in the Calabar province of Nigeria. It is more common in the Cameroons.

It is a small tree, with large white flowers with a pretty, reddish streak in each petal. The pod is of usual Afzelia size and appears rather large for the size of the tree. The type specimen stands on the Calabar Golf Course, between the seventh and eighth holes. It is apparently uncommon, though more may be found on closer study of the forests. The fruits appear to have the same qualities as those of other Afzelias. In Nigeria it has so far not been utilized. The bark is not so scaly as that of A. Africana.

Afzelia pachyloba (nov. sp.). Forest Afzelia or Yellow Aril. Apa (Yoruba); Orodo (Benin).

It is a medium-sized tree, with long, pointed nuts with a bright sulphur-coloured aril instead of the orange-colour of Africana or red of Cuanzensis. It does not appear to be such a common tree as A. Africana, but much the same number of trees as that of A. cuanzensis.

It is found in the evergreen forests of Ondo, Benin and Abeokuta provinces of Nigeria.

The sapwood is white and the heartwood is brown. It is very hard, almost as hard as Lophira, according to the natives. Self-sown seedlings do not appear in large numbers.

It is used for similar purposes as A. Africana. It is a shade-bearing and soil-improving tree.

No separate report has been made on the timber, and so far it has not been exported to the English markets.

This may be the tree which yielded the so-called teak in the Benin forests some years ago, and fetched a price of 5d. per foot superficial.

The bark scales off in a similar way to Afzelia Africana.

Afzelia bracteata (T. Vogel). Benin Bilinga. Ekpagoize (Benin).

It has a red flower, is found in the Benin province, but is apparently rather rare.

The Benin name indicates that it is the Ekpagoi or Berlinia of the waterside. It is usually found near or on the bank of a stream. It is a large tree, which is otherwise similar to the other Afzelias.

The natives have apparently not tried it for building purposes.

Afzelia Africana. Yoruba Bilinga. Apa (Yoruba); Olokokima, Aligna (Benin); Ayibukpo (Efik); Adja, Arachi (Asaba Ibo).

Trade Name.—Bilinga, similar wood from the French Congo, so named for some years.

It is found in the Abeokuta, Ibadan, Ondo, Benin, Owerri, Onitsha and Ogoja provinces of Nigeria.

The round, orange-coloured aril at the base of the black nut is typical of this tree. It sometimes has a reddish tinge, but it is always round and completely surrounds the base of the nut, in contradistinction to A. cuanzensis, in which the aril is red and pointed and much thinner in build.

The spherically-shaped crown with its flattish top is most typical of this tree. The largish leaves and the paucity of their number make the foliage open, so that daylight can be seen through it. In the distance it appears dense.

The sapwood is white, and the heartwood a rich oak-brown colour. It is one of the most durable West African timbers. It planes well and can be worked up with a good finish. It does not split well. It is obtainable in logs up to 30 inches square and 30 feet in length.

Though slow in growth it would average that of many European trees. It stands a good deal of shade in its youth, but it is really more of a light lover than a shade-bearer. Self-sown seedlings are few; apparently rodents eat them. In a similar way it is difficult to make a plantation, many being eaten or dying in the transplanting. One of the most successful methods evolved is that of sowing seeds in lines about 4 feet apart; a large number then come up and provide ample for a crop on the same land. They are not transplanted. When of middle age it will stand fire and the shade of the tree keeps the ground moist.

It is a soil-protecting and soil-improving tree; good crops of seeds are borne almost every year. The flowers are reddish, with white edges to the petals. The reddish tinge is quite distinctive in this genus, the white being that of Berlinia.

The bark drops off in large scales in places on the trunk towards middle and old age, in a similar fashion to the European plane. However, they do not leave the stem as smooth, though the lighter patches where the bark falls off brighten the bole up and make it quite distinctive amongst the other trees.

The timber has been constantly used by the P.W.D. at Onitsha. In the Liverpool market it was stated that it might be marketable as oak, at a low figure, in 1906. A similar species was being shipped from Gaboon in 1914 and fetched a fair price.

Albizzia fastigiata (Oliv.). East Indian Walnut. Ayinre langara, Ayinre ogo (Eg.) (Yoruba); Uwowe Lugu, Uwowelabafun (Benin); Uyat (Efik).

It is a large tree, up to 7 feet in girth and of corresponding height. Fruit narrower than A. sp.; only half an inch, with four or five seeds in each. This species has the most durable wood of all the Albizzias, but is not termite-proof, and has heartwood of a brown colour and white sapwood. The smallest leaf of all the Albizzias is met with in this tree, having very fine pinnæ.

Although not indigenous to Africa, it is now found almost everywhere in all the mixed deciduous forests of the Southern Provinces of Nigeria. The bark is rather rougher than that of A. Brownii. The basal root spurns are narrower, though they do not project more than 2 feet up the stem. On the whole the foliage is thicker, and the crown gives the appearance of being a little denser and not so feathery as that of A. Brownii.

The wood planes well, splits fairly easily, takes nails and saws well. It is what the carpenters would call a wood easy to work. The grain is of fine texture and has a certain amount of lustre.

It is a fast-growing, light-loving tree, which does not protect the soil. The leaves, however, form a rich humus, which enriches the soil. Natural regeneration appears to be good, and with the spread of farms this tree tends to increase its area of distribution. It will stand a little shade in its youth. A few plantations have been made with this tree.

Up to the present the timber has not been exported, but deserves a trial as an African Walnut, though it is difficult to obtain large-sized logs. It has occasionally been cut for local use. It is used by the natives for firewood, and occasionally, when split, for temporary house-building in the farms.

Albizzia Brownii. African Walnut. Ayinre, Ayinre Bona Bona (Yoruba); Owewe nolemare, Ikpawudu (Benin).

It is a large tree, up to 7 feet in girth, with wide fruit 2 inches across, containing four or five seeds. There are three or four pairs of pinnæ to each leaf, which is the largest of all the Albizzia leaves. The heartwood is more like walnut in colour, though of course softer and with more open grain. It could no doubt, however, be used as a substitute for walnut.

It is a common tree in the mixed deciduous forests of the Abeokuta, Ibadan, Benin, Owerri, and Ogoja provinces, where it is tending to widen its area of distribution with the spread of cultivation.

The fruit is very papery and almost transparent. It is rather larger than Albizzia sp., Shemusholoshi, but of about the same length. Its smooth, almost orange-coloured bark in the earlier stages is almost typical of the tree. As it gets older, a somewhat more corky bark forms in large scales which can be stripped off. The lop-sided shape of the pinnæ is very typical of the tree, making the leaves look almost like those of a true Gum Copal. The main vein is near the straighter side of the leaf.

The sapwood is white and the heartwood a mahogany brown. It has rather an open grain, but a good deal of lustre, and is easily worked. It planes well and takes nails easily. It splits fairly well and saws quite easily. It is not quite so durable as A. fastigiata, but it is more durable than the other Albizzias, except A. sp., Shemusholoshi. It is not termite-proof. It has considerable tensile strength compared to the other species, and a certain amount of elasticity.

It is the fastest growing of all the Albizzias and a light-loving tree. It scarcely protects the soil, but the leaf fall makes a good humus. It stands a little shade in its youth. Natural regeneration is very prolific. No plantations have been made with this tree. It appears to be a little more exacting as to soil than the other Albizzias, but will grow on almost any soil.

The timber has not been exported, but deserves a trial as a substitute for walnut. Owing to the fact that there are considerable supplies, and that it reaches a size to produce logs of the requisite dimensions, it appears to offer some possibilities as an export wood. Locally it has often been used for cutting up into planks, and is liked among the Yorubas for this purpose. In other places it has been used as a house-building wood, as well as for firewood. It has also been used for making beams, planks and doors. The roots, leaves and bark have been used amongst the Yorubas for medicinal purposes.

Albizzia sp. Walnut. Owewe nolemare (Benin); Ayinre (Yoruba); Semusholoshi (Jebu); Akkihien, also Owewe lagebon (Benin).

According to Mr. H. N. Thompson, Chief Conservator of Forests in Nigeria, who has seen the fruit of this tree, it is most certainly an Albizzia.

Chief Characteristics.—It has been described by a German as not unlike a solitary-standing pine, with its dark foliage of small pinnate leaves, which are larger than Piptadenia Africana and yet smaller than Cylicodiscus Gabunensis. In the above description it is very similar in habit to Piptadenia Kerstingii. The dark brown bark, which is roughish, is light-brown on the upper part of the stem. The crown is flat, consisting of two or three wide, outspreading branches. It has the usual flat, papery pod. The leaves are used by the Benin people for soup.

Distribution.—It is found in the Abeokuta province of Nigeria.

Timber.—It is fairly close-grained, though not nearly so hard as either Piptadenia Africana or Cylicodiscus Gabunensis.

Use.—The Yorubas use the bark medicinally as a stomachic, and the trunk is usually swollen at the base owing to the cortex being removed so often.

Albizzia rhombifolia. Walnut. Ayinre, Ayinre langara, Ayinre ogo (Yoruba); Owowe (Benin).

It is found in the Ibadan and Benin provinces of Nigeria, in the mixed deciduous forests, where it is quite prevalent. It is a medium-sized tree, attaining a girth of about 6 feet and a bole length of 30 feet. It is commonly seen in old farms, and usually more than one is found in the same locality. The thin, yellow, spiky flowers are rather pretty. The fruit is rather smaller than that of the other species.

The sapwood is white, and the heartwood is a light yellow-green. It is soft and not very durable; it is attacked by white ants (termites). However, it saws well, planes well, takes nails easily and splits moderately well. It can be cut into good-sized planks.

Timber, yellowish-green, and yields large planks.

It is a fast-growing, light-loving tree, which scarcely protects the soil, and only slightly improves it with its leaf fall. Natural regeneration is good, the seedlings growing up rapidly in any open place in the mixed deciduous forests.

The timber has not been tried for export, nor has it been used to any extent for local use. It deserves a further trial both as an export wood and as a wood for local floor-boards. Its qualities are far from properly known.

Among the natives it is used as firewood.

Albizzia sp. Walnut. Ayinre Ayinre, Ayinretta (Yoruba); Ikpawudu, Owawelugu (Benin).

It is a large tree, up to 6 feet in girth. It has rather narrower pinnæ, but of similar round shape to A. Brownii.

It is a common tree of the mixed deciduous forests in the Abeokuta, Ibadan, Ondo, Benin, Onitsha, Owerri and Ogoja provinces of Nigeria.

The root spurns are very small. The bark gets rougher than that of A. Brownii in old age, the crown is longer and more feathery, and the leaves appear to be more of a silvery green.

The sapwood is white and the heartwood is of a yellowish-brown colour, tending to become a light brown when exposed to the air. It is comparatively soft; is not termite-proof. It is easy to work, planing and sawing well, and taking nails easily and splitting fairly well. It is, however, less durable than A. Brownii or fastigiata. When split and dried it is more durable than when cut up in the ordinary way. The wood hardens very considerably on exposure to the sun.

It is a light-loving, fast-growing tree. It scarcely protects the soil, but the leaf fall enriches it. Natural regeneration appears to be good. It tends to spread with the increase of farms, more especially on the poorer laterite soils. A few plantations have been made with this tree. The volume of produce per acre is less than in the case of A. Brownii, but apparently greater than any of the others. It is less rapidly growing than A. Brownii, but faster than the others.

The timber has not been used for export, and it is doubtful if it would repay the cost. Locally it has been used for planks, but it is not liked so much as that of A. Brownii or fastigiata. By the local people it is used for firewood, and occasionally for building temporary houses.

Anglocalyx ramiflorus (Taub). Ekiyawa (Benin).

It is a large tree, attaining a girth of 8 feet, but the trunk is not over-long in proportion. It is a shade-bearing, soil-protecting and soil-improving tree. The bark is a dark olive-green and smooth. It is found in the Benin province of Nigeria. Natural regeneration appears to be poor. The wood is yellowish-brown and floats when quite dry. The timber was valued at nothing in 1906 and stated to be a whitewood in the Liverpool market.

Native Use.—None.

Ostryoderris impressa. White Oak. Awaw or Erumacie (Yoruba); Ori, Ehrurumesi, Erurunuesi, Awaw, (Usshin) (Benin).

It is a common tree in the Calabar, Ogoja, Benin, Owerri and Abeokuta provinces of Nigeria. To be seen along the Benin-Siluku Road, as also in the Badagry district on the Ayobo-Osuke Road.

It is a straight-boled, tall tree, with flattish crown made up of few straight branches with large pinnate leaves, making it appear flatter than it really is. The bark is slightly scaly with fine fissures. The slash is red, exuding a red latex. It reaches a height of 150 feet with a girth of 12 feet. The white, papery, pointed, flat, lozenge-shaped fruit, with a small kidney-shaped seed attached to the centre of the surface of one side, is most typical of the tree. The spurns are almost non-existent, so that the tree can be felled near the ground without trouble.

The timber is white in the sap and brown-white in the heartwood, but not over-hard, very tough and not splitting easily. It is hard to fell, being very flexible. It planes moderately well. The colour darkens with age.

It is a light-loving tree after the first few years. It grows moderately rapidly. It is a soil-improving and covering tree. Natural regeneration appears poor, though many seeds are usually seen on the ground. Insects appear to eat them rapidly. No plantations have been made with this tree, but experiments would show whether it grows well from seed.

In 1906 a sample log was exported and sold in the Liverpool market as white oak at 2s. per cubic foot, and it was recommended for shipment by the brokers.

Native Use.—It is used as posts for frames on which yams are tied in the Benin farms. In temporary houses, small trees are trimmed and squared for the forming of the walls, instead of dried mud.

Dalbergia saxatilis. West African Blackwood (?). Awow (Benin).

It is a small tree of the mixed deciduous forest of Benin; it is occasionally used by the natives for hoe and axe handles.

Dalbergia sp. West African Blackwood. Emosobegan, Paran (Yoruba).

Found in the Olokemeji Reserve.

Dalbergia sp. North Benin Blackwood.

This is found near Aroko, in the Onitsha province, and near Ishoka, in the Benin province. It is a small tree with very hard wood. In habit very similar to Ormosia laxiflora, with its orange-coloured bark, which is rougher than O. laxiflora and not so scaly. The wood is used for axe and hoe handles by the natives.

Dalbergia hostilis (Benth.). Yoruba Blackwood. Ogan Oga (Yoruba).

This Dalbergia is fairly common in the Olokemeji Reserve, in the Abeokuta province of Nigeria.

Copaifera sp. True Benin Gum Copal.

This tree is found near the Uhi, close to the source of the Ossiomo River, Benin province. This apparently is rather an uncommon tree. The Benin natives do not know how to tap the tree for gum, nor how to use the gum.

Cf. Copaifera. Enyenewu. Enyenewu (Yoruba).

Found in the Yoruba country.

Copaifera sp. Boji Hills Copaifera.

So far it has not been tapped for the gum, the local people apparently not knowing its value.

Bauhinia rufescens (Kew).

Found in the Oyo province.

Bauhinia reticulata (D.C.). Dry-zone Bauhinia. Abafe (Yoruba).

This Bauhinia grows in dry, open country. It is a small, spreading tree bearing white flowers.

Uses.—The fibrous bark is used for tying, and an infusion from the leaves is used in coagulating rubber latex. The stem is occasionally used for making house-posts. It is a fire-resisting tree and shades the soil.

Bauhinia Thonningii (Schum.).

This is a small shrub-like tree of the upper part of the Benin province of Nigeria. It is found near Agbede. It has red flowers. The sap of this tree has sometimes been used for coagulating rubber.

Physostigma venosum. Calabar Bean or Ordeal Bean. Eseri (Efik).

It is found growing in the Calabar district. The seed is poisonous; used in ordeals and medicinally.

The most noticeable feature is the furrow (about ⅛ inch wide and deep) in the upper side of the bean. None of the closely allied Mimosa species show this peculiarity.

Entada scandens. Sword Bean, Match-box Bean, Mackay Bean. Kakoba, Akhuro (seed) (Benin).

This large creeper is found in the Benin and Calabar provinces of Nigeria. It is not very prevalent. The most remarkable features about it are the stoutness of the stem, which attains a diameter of nearly 1 foot and the total length of over 100 feet, and its immense pod, which is often over 3 feet in length. The pod is divided into segments, each nearly 2 inches square, and each containing one large bean, almost a square in shape, 1½ inches and nearly ¾ inch thick. These beans have occasionally been used for making match-boxes, for which they are admirably suited. The outer part of the stem of the creeper is very rough and almost corrugated, especially near its base; the leaves are very small, considering the size of the whole creeper. It is comparatively slow-growing. It grows in the dense evergreen forest, and when drawn taut over the first branches of one of the large trees it is not unlike the bole of a small tree itself. When cut, the two ends part with a bang, like the breaking of a ship’s hawser. The natives use the smaller parts of the stem for fly-switches, for which they are very good and durable. The creeper is, however, not cultivated.

Entada Soudanica. Ogurohe (Yoruba).

Found in the Ibadan province.

Entada Abyssinica. Unwanwanis (Benin).

It is found in the upper part of the Benin province near Ishoka. It is a large creeper with rather smaller bean than E. scandens. The beans have been used for making small match-boxes in Europe. The natives consider the bean a “Ju-ju.”

Dioclea reflexa. Ishe, Agbarin (Yoruba).

A climber, found in the Ibadan province.

Mucuna urens. Ox-eye Bean. Awipu (Benin).

Found in the Benin and Abeokuta provinces.

Mucuna sp. Preussii. Yerepe (Yoruba).

Found in the Olokemeji Reserve and Benin province.

Acacia pennata (Willd.). Acacia. Okwekwe (Benin).

It is found in the upper part of the Benin, Ibadan, Ogoja and Abeokuta provinces. It is a small, scandent shrub with very sharp thorns, but which yields one of the strongest fibres for making fishing lines or native rope. It forms almost impenetrable masses which are very unpleasant to go through without a matchet.

Acacia Sieberiana. African Rosewood. Sie (Yoruba).

This is a somewhat uncommon Acacia of the Oyo province of Nigeria. Being of medium size, its very handsome racemes of yellow flowers show up to great advantage. The bark is rough, the bole short, and usually divided 8 or 10 feet from the ground. The sapwood is white and the heartwood a rose-pink colour, which makes it not unlike the typical rosewood of commerce. The heartwood is comparatively wide, and it is very hard, durable and termite-proof. It saws well and splits moderately easily, but does not take nails at all well. Reproduction by seed is apparently poor; it sprouts fairly well from the stump. It is a light-loving species, but being of the leguminous family it is a soil-improving tree. The wood has not yet been exported, but locally it has occasionally been used for house-building, the forked stem being much appreciated by the natives.

Acacia Farnesiana (Willd.). Farnesian Acacia. Bonni (Yoruba).

It is found in the Abeokuta province of Nigeria. It is a small tree growing up to 6 feet in girth. It has a small pod containing eight seeds inside. The inside of the pod is white and the seed is brown. The flower is yellow, and is used by girls in decorating their ears. Usually found in towns, where it is planted. The seeds are sold in the market.

The timber is dark-red, surrounded by a narrow white sapwood. It is hard, like ebony. The bark is very much fissured and peels off in large scales.

The seeds of this tree and Jagiri are used with water for scraping the leather for making the fells smooth. Sold at Itaku and Shapon markets.

Acacia campylacantha. Confectioner’s Gum or African Catechu. Ede (Yoruba).

It is found in the Abeokuta, Oyo, Borgu, Niger, and Nassarawa provinces of Nigeria.

It is a very common tree, growing almost everywhere in groups. The stem is of a whitish to slight yellow colour, almost reminding one of the larch, but the whole tree is armed with short, sharp thorns. It reaches a girth of nearly 4 feet and a height of over 50 feet. The slash is light-brown, and a pale, yellowish-pink gum exudes from it. The tree usually forks about 20 or 30 feet from the ground, the other branches being rather crooked in shape. In February or March a mass of small yellow flowers appear, and in the autumn small pods cover the tree. The sapwood is white, and the heartwood varies from a dull red-brown to a rich, almost rosy red. In the latter case it is exceedingly pretty wood. The wood is moderately hard; it splits and planes badly, saws fairly well, and only takes nails indifferently. The wood dries rather harder and is more durable than when freshly cut and than would be expected. It is said to be termite-proof. A reddish colouring matter exudes from the heartwood, but this feature is typical of the cutch which is obtained from a similar tree in India.

Natural regeneration by seed appears to be good, hosts of young trees being found near the older ones. In fact, in localities of low rainfall it is tending to spread and fill up all vacant spaces after the annual grass-fires have burnt all the vegetation. It is a light-loving tree which does not protect the soil. The leaves are not unlike conifer needles, and enrich the soil to a certain extent, more especially as the tree is deciduous.

As a timber it has not been cut for export, but certainly the better-coloured wood, and that which has been more slowly grown, deserve a trial.

So far, the greatest use of this tree has been the production of the pink-coloured transparent gum which is one of the best of the confectioner’s gums in Great Britain. Very large quantities are exported every year from the Northern Provinces. Large round tears or lumps form on the stem of the tree when it is cut. Locally the tree is used for house-building, but it is not considered a durable wood.

Leguminosæ (Mimoseæ).

Acacia ataxacantha. Benin Rope Acacia. Ewon (Yoruba); Okwenkwen (Benin).

A common creeper of the mixed deciduous zone. It is found in the Abeokuta, Oyo, Ibadan, Ondo, Benin, Warri, Onitsha, Owerri, Calabar and Ogoja provinces of Nigeria.

It is usually found growing in large impenetrable masses 3 to 4 feet high. It is armed throughout with short but very sharp, bent prickles.

It often grows up in waste places where the bush has been cleared in the mixed deciduous forest zone.

Both the Yorubas and Benis use the inside fibres of this creeper for making a very strong kind of rope—in fact, it is the strongest of all native-made ropes. It does not get so stiff or harsh as that made of Eso from the Firmania Barteri.

Distemonanthus Benthamianus (?) (Baill.). Alinyan (Benin).

Found in the Benin province.

Erythrina suberifera (Kew). Attagbo (Yoruba).

It is a moderately common tree of the Abeokuta province of Nigeria. Its most distinguishing feature is the size of the leaf, which is similar to the tulip-tree. It reaches a much larger size than E. Senegalensis and has a girth of over 6 feet. The bark is a dark duck-egg-green colour, with a few white, shallow longitudinal fissures. The prickles on the stem are more scattered and much larger than those of E. Senegalensis. The slash is white and the bark thin when compared to the size of the tree. The wood is white and soft, and not durable. It cuts and saws easily, but does not plane well. It is a light-loving tree which does not protect the soil. It has not been cut for local use, nor for export. As a soft whitewood for interior use it ought to find a local market.

Leguminosæ (Papilionaceæ).

Erythrina Senegalensis (D.C.). Coral-flower. Ologun she-she (Yoruba); Esanigbakhehe, Ohehe (Benin).

It is a common tree in the upper part of the Onitsha, Benin, Ondo, Ibadan and Abeokuta provinces of Nigeria. One of the most typical features of this small tree are the small, pink, coral-like flowers which appear in February. The tree is armed with a few thin but very sharp thorns; the foliage is slight and open. On suckers or stool-shoots the leaf is much larger and almost lyre-shaped. It is usually found in waste places or in open clearings in the mixed deciduous forest. It yields a soft wood which is not durable. It is sometimes used for making fences.

Tephrosia Ansellii (Hook). Boro (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Tephrosia Vogelii (H. K. F.). Fish-poison. Were, Igun, Laye Igu (Yoruba).

This small shrub is apparently indigenous to Africa, but is usually seen planted in the fields of the Abeokuta, Oyo, Benin, Owerri and Ogoja provinces of Nigeria. It is not unlike a large upright vetch, but with a strong, green stem, almost woody in growth. It reaches a height of about 3 feet and flowers very profusely, and bears a large number of pods, not unlike those of the runner bean. The plant is cut down and placed in the water where it is desired to catch all the fish, chiefly in stagnant pools of rivers or ponds. The effect of the poison from it blinds and stupefies the fish so that they are easily caught. Under the Game Preservation Ordinance, its use has been prohibited, but with its widespread cultivation and general utility it has been found very difficult to eradicate the custom or the plant. Incidentally it is a very good green manuring crop for agricultural land. However, most natives are unaware of this fact, and it is usually only planted for the purpose of using it as a fish-poison.

Burkea.

A species of Burkea was found near the Oyan River in the Oyo province of Nigeria.

Lonchocarpus sericeus. African Wisteria. Ipapo, Apapo (Yoruba).

This tree is found in the Olokemeji, Ibadan, Ilesha and Calabar districts. It is a medium-sized tree, which bears lilac-coloured flowers. As the flowers appear before the leaves in the dry season, it is then very ornamental, and is in fact one of the prettiest flowering trees. The wood is very hard and the heartwood green when freshly cut.

Timber.—This is not of much service.

Uses.—Hoe-handles are made from the branches, and the bark is used in medicine.

Lonchocarpus sp. Mamu Lonchocarpus.

Found in the Mamu Forest.

Lonchocarpus cyanescens. Yoruba Indigo. Elu or Ela (Yoruba).

This is one of the intermediate forest climbing shrubs, but has been cultivated throughout the country.

Uses.—The well-known Yoruba blue dye is made from the leaves. The stem is sometimes used for house-building posts. It is a shade-bearing, soil-improving tree. Natural regeneration appears to be poor.

Cæsalpina Bonducella. Shayo (Yoruba).

The bean of this creeper is used in games amongst the Yoruba boys.

Mundulia suberosa (Benth.). Lakuta (Yoruba); Ugbehen (Benin).

It is rather an uncommon tree, found in the Olokemeji Reserve of the Abeokuta province of Nigeria. It is a small tree, a part of which is used for killing fish.

Indigofera hirsuta. Indigo. Epa ile (Yoruba).

It is found in the Mamu Reserve of the Ibadan province of Nigeria.

Indigofera stenophylla. Indigo. Aro Boro (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Pentaclethra macrophylla. The Oil Bean. Apara (Yoruba); Opagga, Ukpagga (Benin); Ataka (Ibo, Asaba); Opochala (Ibo, Niger).

It is a large-sized tree, reaching a girth of about 12 feet and a bole length of 40 feet. The root spurns are very extensive and often reach 4 or 5 feet up the stem, thus quite breaking up the base of the bole. The bark at first is a light yellow-brown, darkening in old age to a deep brown, and scaling off somewhat.

Chief Characteristics.—It has dense foliage and a heavy, branched crown, and very flat pods about 1 foot long and up to 2½ inches broad, containing seven or eight large, flat brown beans about 1 inch in diameter and ¼ inch thick. The pods open with a loud report not unlike the sound of a 12-bore gun.

Distribution.—It is found in the Lower Province of Nigeria, near the watercourses outside Abeokuta, Jebu, Ode, Benin, Onitsha, Owerri, Calabar and Ogoja.

Silvicultural Qualities.—The tree grows readily from self-sown or artificially sown beans, as is seen in the Avenue at Benin City, which was sown at stake in 1904. It bears pods in the twelfth year in the open, but later in the forest. It is usually very prolific, bearing at least some pods every year. The bole is not always very straight, and it has a distinct tendency to form strong side branches, and the crown is therefore a large oval one. The flowers are little yellow spike, which are very inconspicuous; they are borne on the old wood rather on the underside of the twig, in November or December and later. The tree stands dense shade, and it thoroughly covers the ground and prevents the growth of weeds.

It has a tendency to branch comparatively low down, when growing as an avenue tree, and thus does not grow so tall. This, however, has an advantage that the large pods have not so far to fall to the ground, and thus are not so dangerous to passers-by. The oil-beans have been collected and sold in England in small quantities.

The sapwood is of a dirty white colour and the heartwood of a dark brown, forming comparatively early in the life of a tree. The wood is very hard, but sometimes rather soft-grained, rather fibrous in texture, and the pores are somewhat wide and deep. It does not plane well, splits with difficulty; holes have to be made before nails can be put into it, and it saws none too easily. It is very durable and termite-proof. Considering its hard wood and comparatively early production of seed, and the huge pods, it is by no means a slow-growing tree. It reaches a height of 9 to 12 feet in twelve years. The pod is the stoutest and largest, but not the longest, of all African timber trees. The beans are collected in boxes and sold to the factories at 6d. to 9d. each. To be made quite safe for eating they have to be boiled nearly twelve hours, the outer husk of the bean being rather hard, though not very thick. The future will alone show whether this tree will prove of greater value for timber or oil production.

Uses.—The timber has been shipped to Europe and sold as greenheart at 1s. 6d. to 1s. 9d. per cubic foot. Locally, in the Benin City district and elsewhere, it is used for making mortars for beating yams and other food. The beans are eaten by the natives in most parts, though they are not considered a delicacy. The empty pods are used where firewood is scarce, as they burn well. It is, and has been, very extensively used as a shade-tree for public roads in the Owerri district, as well as in Afikpo and Benin. Some people object to the falling pods, but it is an excellent shade-tree, especially in the dry season, as it is an evergreen tree. It is a soil-protector, and would do for underplanting or interplanting teak.

Pterogopodium. Agba, Pink Mahogany. Asokale, Asu Kole (Ikale); Asre (Yoruba) (Egbado); Agba (Benin).

The scattering of the white flowers on the path or roadway is an indication of the presence of the tree, quite apart from the wonderful bole, exceeding nearly all others in cylindrical shape.

Chief Characteristics.—It is a very large forest tree, with clear bole of 90 feet and open crown formed with two or three large, upspreading limbs, flatly oval on the top. It is quite reminiscent of an old elm in the shape of the crown. The single-seeded winged fruit is most typical, no other species of Leguminoseæ having a similar seed except the nearly related Pterolobium (?). The bark is comparatively thin, silvery-grey in colour, with a few more or less well-defined ridges running horizontally round the trunk here and there. These are most typical, and it is the only tree which shows them. In some places they amount to small nodules of bark.

This tree is found commonly in the Benin and Ondo provinces of Nigeria, where it is prevalent, and in the northern part of the Benin province, and seen in almost gregarious patches in the secondary forest. The slash is yellowish-white, and in the younger trees a dirty pinkish sap exudes, but later on, especially from deep cuts, the gum copal forms and gradually hardens into solid lumps of various size.

Silvicultural Peculiarities.—It loves a deep soil with plenty of moisture, which may even be flooded or partially waterlogged during the rainy season. A chalky or limy soil seems to suit it best. It is a fast-growing, light-loving tree, though it stands a little shade in its youth. The light, feathery foliage does not shade the ground, though when in falls it enriches it. The root spurns are most slight, extending only from a few inches to 1 foot above the surface of the ground; in fact, sometimes the trunk appears to come straight out of the ground, like a round log on end. Natural regeneration is none too good, but this is chiefly due to lack of light in the mixed forests. No plantations have yet been made with this tree.

It has not been exported, but it deserves a trial as a furniture-wood for drawing tables and office equipment generally. It is sawn up into planks and boards at Koko Town, and contains a gum which makes the saws stick a little. It makes a good, soft wood for table tops, of a pinkish colour and clear, close grain. The gum is sold.

Native Use.—It has been used for canoe making in the Ondo province. The gum is used for an illuminant, and was at one time used entirely for this purpose. In 1906 logs of this timber were sold in Liverpool market as a kind of mahogany of light colour.

Prosopis oblonga. Yoruba Charcoal Wood.

It is found in the Ibadan and Ogoja provinces of Nigeria, and may yet be found in the Onitsha and northern part of the Benin provinces. On the whole, it is not common, and is seen singly. Two typical specimens of this tree stand in the Olokemeji Reserve Arboretum. It has small, pinnate leaves, very much like tamarind, but they are almost silvery-grey and hang down, instead of being green and rigid, as the tamarind. The twigs and branches are very slight, compared to the thick ones of the tamarind. The bark of the trunk is grey, too, with thin cortex, which becomes slightly fissured in old age. The trunk is straight and tall, compared to tamarind. The crown is longish and thin, with a few small branches. It is somewhat feathery in habit and is delicate in build compared to most dry-zone trees. It is one of the most typical of dry-zone trees. The seed is small, about the size of apple-pips, contained in a papery pod, from 1 inch to 1½ inches long. It stands the annual grass-fires comparatively well, despite the fact that the bark is none too thick.

Timber.—Hard, white wood, termite-proof and very durable. The bark is thin but rough, and small pieces can be pulled off with the fingers. It is a deciduous tree, though it does not lose its leaves for a long period. It is a light-loving tree, which does not protect the soil, though the leaves (few as they are) make a good leaf-mould. It is slow-growing, and does not reach a girth exceeding 5 feet. Natural regeneration appears to be poor, but further observations on this point may disclose more. No plantations have been made with this tree, though, with its desirable qualities, some experiments seem to be indicated. It does not sprout well from the stump, nor do any root shoots appear before or after it is cut down.

It has not been exported, and has only been used occasionally locally.

Use.—The timber has been used for sleepers in Togo, where it has proved the most durable of all timbers for that purpose. In the Yoruba country it has been used for making charcoal of the best kind for iron-smelting.

Detarium Senegalense. Hard Mahogany. Ogwega (Benin).

This is none too prevalent a tree of the Benin and Ogoja provinces, where it is found in the mixed forests. It reaches a girth of over 12 feet and a bole length of over 40 feet, but in proportion to its height, the crown usually occupies more than half of it. The crown is usually widespreading and spherical in shape. The fruit is like a mango in form, but after the surface begins to decay, the fibres, instead of being fine and all coming out from the central nut, as in the mango, spread out vein-shaped all round the nut, starting more or less as thick veins at the base, and then subdividing into thinner ones, spreading round the nut in an irregular manner. The decaying fruit has a most unpleasant, not to say distinguishing, smell. However, this is more than compensated for by the pleasant taste of it when served as stewed fruit.

The sapwood is whitish-yellow, and the heartwood brown-red. It is hard, with somewhat fibrous grain, yet planes up with a good surface. Takes nails, but does not split well. It is durable, and supposed to be termite-proof, except for the sapwood, which the white ants often destroy. It saws moderately easily. In older trees the wood sometimes shows a little figure.

It is a somewhat slow-growing tree and a shade-bearer, with soil-protecting and soil-improving qualities. In fact, in most cases it is only found on comparatively rich soil, and in this respect appears to be more exacting than many other trees. Natural regeneration does not appear to be very good, but this may be due to the fact that animals eat the seeds. No plantations have been made of this tree.

In 1906 samples of this timber were sold in the Liverpool market as mahogany at 2¾d. per superficial foot, 3s. per cubic foot. It was reported to be of very hard texture, a dirty brown colour, and only one log sold. Since that date, however, none has been exported. It has not been felled for local use. The fruit can be stewed, and makes a nice addition to the other African fruits.

Native Use.—The shell of the nut is used for making prayer-beads and strung on a wire.

Ormosia laxiflora. Shedun (Yoruba).

Found in the Olokemeji Reserve and Ibadan province.

Paradaniellia Oliveri. Ilorin Balsam, African Balsam of Copaivi, Balsam. Iya (Yoruba); Osia (Benin); Ozia (Ishan); Ozaba (Ibo Asaba).

Found in the dry zone of the Southern Provinces of Nigeria. A common tree, growing to a height of 40 or 50 feet.

Use.—Balsam of Copaiba.

Xylia Evansii. Bentpod.

It is found in the Ogoja province of Nigeria in the mixed deciduous forest zone, but it is by no means a very common tree.

A medium-sized tree, with the curious bent-shaped pod typical of the Xylia, found in the Obubra and Ikom districts of Nigeria, on the left bank of the Cross River. It has a hard, red wood, which splits well. The sapwood is white, but not very wide in an average-sized tree.

It is a slow-growing, shade-bearing tree, which thoroughly protects the soil and improves it with its leaves decaying year after year.

The natives have not used the tree, nor has it been felled for local use by Europeans. It has also not been tried for export.

Pandanaceæ.

Pandanus candelabrum. Screw Pine. Ebbo (Benin).

In some rivers of the Abeokuta, Ondo, Benin, Warri, Onitsha, Owerri and Calabar provinces of Nigeria it is a common watershrub or small tree. Often it is seen only a tangled mass of long prickly leaves, armed with spikes all down each side and half floating in and above the surface of the water. Sometimes, again, it is seen as a tree with two or three more or less complete whorls of branches on the uppermost part of the stem and a mass of drooping leaves from the crown. The white stem is supported by several soft, corky-looking aerial roots. It seldom exceeds 2 feet in girth and 30 feet in height. The white flower is very conspicuous, with its cone-like shape, which becomes more pronounced as the fruit begins to ripen and turns green. The scent is very pungent and overpowering. The trees form almost impenetrable thickets at the edge of the more sluggishly flowing rivers. These often impede navigation and have to be cut away.

The stem is very porous when dry, and cannot be said to yield timber, though the cork-like material might serve for a light substitute for it.

Natural regeneration appears to be very good.

The fibre has not been exported in any quantity, but it is very tough, and apparently very durable and of moderate length (average 3 feet).

Native Use.—When dried the leaves are used for making mats for wrapping goods as well as for sleeping-mats. In the Benin and Jekri country, long (2 feet) thin receptacles are made which are used for salt, which is sold in these bags in the market. The bag keeps the salt dry. It is sometimes planted near villages in damp places for the purpose of obtaining the mat material locally, where it is not found naturally in the swamps.

Humeriaceæ.

Aubrya Gabunensis. Brass Mahogany-bark Tree.

This is a very large forest tree of the Brass district, with a bark very similar to that of mahogany, but to which it bears no relationship.

To face p. 308.

The trees are sometimes cut down by the natives and used for large dug-out canoes. The timber is termite-proof, and the natives say that canoes made from this timber are very durable, though rather heavy, and liable to become waterlogged when filled with water. It is of a dull reddish-brown colour and has rather a coarse grain.

Rutaceæ.

Zanthoxylum Senegalense. Dry-zone African Satinwood. Ata, Odan (Yoruba); Ughahan (Benin).

It is found in the Ibadan, Abeokuta, Benin, Onitsha and Ogoja provinces of Nigeria, at the edge of the mixed deciduous zone and the lower part of the dry-zone forest region. It is only a medium-sized tree, attaining a girth of about 4 feet and a height of about 50 feet. The bole always remains armed with short, woody protrusions, each having a black thorn at the apex. In the upper part of the bole and the branches there are only thorns. The pinnate leaf has usually three pairs of pinnæ and one end-leaf. All the leaves are broader and about only half as long as those of Z. macrophyllum. On the whole, this makes the foliage appear thicker, and, in fact, gives greater shade than Z. macrophyllum. In proportion the bole is shorter and the crown larger and more spread out than in the case of Z. macrophyllum. The bole has a greater tendency to divide lower down into three subsidiary stems, thus spoiling the length of it for timber. The bunches of small, black seeds are smaller than those of Z. macrophyllum, and if anything the seeds are also smaller too.

The timber is very similar to that of Z. macrophyllum, the sapwood and heartwood being the same colour, except that the heartwood is often of a little darker shade, and bears a greater proportion to the diameter of the tree than in the case of Z. macrophyllum. On the whole it is harder, and more often shows a little figure. Although it does not reach such a large size, in many ways it is superior, the grain being rather finer, and showing more sheen, and if anything it works up to a finer texture when planed. It is just as durable and termite-proof. It is a light-loving tree, but will stand a certain amount of lateral shade. Owing to the prevalence of grass-fires, it is slower-growing than Z. macrophyllum, but if anything it shades the ground better, and considering where it usually stands, it is a slight soil-improving tree. Natural regeneration is fair. No plantations have been made with this tree. Samples of this timber have not yet been exported, though, as it is a sister tree to the West Indian Satinwood, it ought to command a similar price. It has not been felled for local use. The natives occasionally cut it for house-building timber, but it is not at all popular, owing to its being armed with spikes.

Zanthoxylum macrophyllum (Oliver). True Benin Satinwood. Atagbo (Yoruba); Ughahan, Okor (Benin).

It is found in the Abeokuta, Ondo, Benin and Calabar provinces of Nigeria, in the mixed deciduous forest zone, where it is very prevalent, especially in old farms.

Chief Characteristics.—It has a very large leaf, up to 6 feet long, with forty pairs of leaflets, each rather smaller than those of Z. Senegalense. There are no thorns on the branches, but many on the stem, which is thoroughly armed until old age, when most of the woody spikes drop off. It bears a large bunch of small, black, spherical-shaped seeds. It is a common tree in abandoned farms of the mixed deciduous forest zone. The thorns are more sharply pointed than Z. Senegalense and not so woody at first, but later form a thorn at the top of each wooden protrusion. One specimen found in the Olokemeji Reserve had very few wooden protrusions, each armed with a thorn, but there were larger leaves than Z. macrophyllum, though in all not quite so long. In old age the stem is almost smooth, and may reach a girth of nearly 6 feet and a length of over 30 feet. The crown is slender and broken up with three or four main branches. The base of the bole in old age is spotted with yellow lenticels.

It is a light-loving, quick-growing tree, which does not protect the ground, and only to a certain extent acts with its leaves as a soil-improving tree. Natural regeneration is very good, and on the whole, at the edge of the evergreen and mixed deciduous forest zone, with the increase of farms it is tending to spread in greater numbers than before, and in some places groups of them are found, whereas in the original forest only isolated specimens are obtained. No plantations have been made with this tree.

The sapwood is light-yellow and the heartwood of a darker yellow shade. In quickly grown trees it is not very large, but in the older trees comprises more than two-thirds of the diameter of the tree. The timber is hard, fine-grained, planing up smooth in texture. It does not take nails well, nor split well, saws, however, cleanly, and occasionally shows a little figure.

In 1906 samples of this timber were sold in the Liverpool market as Sabicu at 2s. to 2s. 6d. per foot, and reported of a very hard nature. Since then, however, none has been cut or exported. Locally it has not been used in any form. It should be noted, however, that this is a sister tree of the West Indian Satinwood, and considering that it grows to a larger size than that one, the timber should demand a still higher price.

Use.—In the Benin country the timber is used for making door-plates before putting dried clay on the top, and also used for doors.

Zanthoxylum sp. n. Dwarf Satinwood. Boji.

Chief Characteristics.—The fruit is a mass of red berries very similar to the Mountain Ash of Europe, but a small tree armed with a few scattered spines of short length, but not very woody, more in the nature of thorns. It attains a girth of 10 inches and a height of 15 to 20 feet.

Distribution.—It was only found on the summit of the Boji Hills from an elevation of 4,500 to 5,000 feet, where other vegetation gave out and only grass grew otherwise.

It has a very hard, yellow wood of the usual satiny nature. It made very good firewood on the mountain top.

Zanthoxylum sp. (Kew). Pterocarpus sp. African Satinwood. Urueben (Benin).

It is found in the Benin and Ondo provinces of Nigeria.

It is a common tree near the banks of rivers in the evergreen forest. It is of medium-size, reaching a girth of about 7 feet; the bole is long (40 feet); the root buttresses reach up the bole about 3 feet. The stalk has a few prickles, especially when it is small, but they disappear in old age. The leaf is smaller than P. osun, but much the same as Akume, Pterocarpus sp. The habit is typical of a Pterocarpus and not of Zanthoxylum. The bark is quite smooth and always unarmed. The fruit is ovoid and flat, with the seed at one end, rather different in this respect to Pterocarpus, and without the prickles on it. The slash is white, and soon red drops of latex-like fluid exude from the tree. The branches are upspreading and the crown is large, though narrow, the bole being about two-thirds of the total height.

The sapwood is white and the heartwood is yellow when young and dark-red, like P. osun, when old. It is hard, but splits well. Termites attack it. It is cross-grained and stands a little bending; otherwise it is brittle, when bent far.

It is slow-growing and a light-lover. It likes a good soil which is moist and has depth. It does not sprout from the stool. Seed reproduction is good, and the seedlings are found in the neighbourhood of old trees. It is a deciduous tree for three months in the year (dry season).

It has not been cut for local use or exported to Europe. It is used for making shovels for mud-puddling in the building of Benin houses; also for pegs in the walls of a chief’s house.

Toddalia sp. Oie (Yoruba).

A climbing shrub common in Tropical West Africa. The fertile stamens are equal in number to the petals. Leaves digitate.

Uses.—Condiments and medicine.

Ægle Barteri. Calabash Orange. Shange, Bale (Yoruba).

This is a small tree growing near the villages, cultivated for its shade and for medicinal purposes. The fruit looks like an orange, but the shell is hard and it is not edible.

Clausena Anisata (Oliv.). Alapari, Obuko (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Simarubaceæ.

Irvingia Barteri. Dika Nut, Wild Mango. Oro, Auro (Yoruba); Ogwi (tree), Okherli (seed) (Benin).

It is found in the Abeokuta, Ondo, Benin, Warri, Onitsha, Owerri, Calabar and Ogoja provinces of Nigeria.

With its smooth, shining, small dark-green leaves it is quite distinguishable from other forest trees. The very spherical shape of the crown and the short bole are also most typical of the tree. It is often found near river banks or in damp localities. Wherever found, it is usually preserved by the natives, though not actually cultivated or tended.

The flower is inconspicuous, but the fruit is like a small mango, becoming quite yellow when ripe, though much harder and of a much sharper flavour.

The wood is hard and durable; the sapwood is yellowish-white and the heartwood yellow. It is impervious to white ants.

The tree is a shade-bearer, especially in youth, but grows very slowly. Those planted near Leopardstown, Calabar, were only 6 to 8 feet high after ten years’ growth. It is true they received little or no attention and occasionally the grass was burnt near them.

No regular plantations have been made, though one plot was planted in the Mamu Reserve in 1910. Further experiments in cultivation, and especially pruning and tending to see how early the tree will bear fruit, are worth undertaking. A method to increase the size of the fruit, and with it the size of the kernel, might be discovered and thus make it a profitable tree to grow in plantations.

Reported on by the Imperial Institute in 1904, and kernels worth £14 a ton then in London.

Native Use.—House-building. The fruit is eaten, and then the nut is cracked and the kernel beaten up and served as soup. Fruit or nuts or both are sold in the markets of Benin and Yorubaland.

Irvingia Smithii. Benin Dika Nut (?). Akwekwe (Benin).

It is found occasionally in the Benin province of Nigeria. It is a tree with similar growth to Irvingia Barteri, but reaches a larger size, up to 12 feet. The bole length is also greater, 40 feet. The fruit is larger than Irvingia Barteri, but of the same shape. It is rather uncommon in the evergreen forest. The crown is smaller and occupies only the upper third of the stem. The branches are larger, too, and of lesser number in proportion than Irvingia Barteri.

The wood is yellow in the sapwood and brown in the heartwood, and hard. It is hard to split. The heartwood is very small, being only about 1 foot out of a diameter of 4 feet. Termites do not attack the wood.

It is a shade-bearer and grows slowly. It does not sprout from the stool, but reproduction by seed is good. The duikas eat the fruit.

It has not been cut for local use nor exported to Europe.

It is used, by tying four seeds together like Ogwega, for a game. The fruit is not eaten because it is not sweet.

Irvingia sp. Pwekupweku (Benin).

It is a common tree in the Benin province of Nigeria. It is a large tree, reaching a girth of 15 feet and very tall. The fruit is yellow, and large as an African mango, but with a very much sweeter smell and sweet taste. The branches are flattish, and so the crown is wide, with a long bole and shallow crown. It has a long, lanceolate leaf with insignificant veins. The wood is hard, with white sapwood and brown heartwood. It grows on good soil, which is moist and deep in the evergreen forests. It is a shade-bearer and grows moderately fast.

Native Use.—The fruit is used for killing rats after it has been cooked and mixed with palm oil chop. It is then given to them, and they at once fall down dead.

Simarubaceæ (Planch).

Hannoa undulata. Whitewood. Igigun (Egba); Igbo (Lagos); Orisi (Igbado, Yoruba).

It is found in the Calabar, Owerri, Benin, Warri, Ondo, Ibadan and Abeokuta provinces of Nigeria.

It is a very large tree, reaching a girth of 12 feet and a bole length of about 50 feet, which grows up very readily in old farms or clearings in the evergreen forest and lower parts of the mixed forests. It has a large, broad leaf, which is deciduous for about a month in the year. The flower, which is white in colour, is in the form of racemes (?). The bark is green, with grey streaks up and down, and the slash is white with yellow markings; it smells sweet, too. The fruit is oblong and black, more like a plum. The spurns are very slight.

The wood is very soft and white all through. It dries without warping, but if not cut properly is liable to be attacked by small borers of the furniture kind. It planes with a smooth surface. It is very light, more so even than Musanga wood. The grain is fine, though such pores as there are, are long. It splits well and adzes well too. It shrinks considerably in drying, but this might be obviated by girdling and drying very gradually in shade when cut green.

It is a very quick-growing tree, almost as fast as Ricinodendron. It is a light-lover, and is rather intolerant of shade, except in its youth. It grows best from seed reproduction, as the power from the stool is very slight and soon dies back.

It was sampled in 1912 at Degema, but has not been exported to Europe. A trial as a wood for making pulpwood seems indicated. It is split up into flat pieces for doors and mantelpieces, also for making the walls of temporary houses, each piece being set upright to the other, with any round edge on the outside.

Burseraceæ.

Pachylobus edulis. Native Pear (Ohan), Incense Tree, Elemi Gum. Ibagho (Yoruba); Onumu (Benin); Eben (Efik).

It is found in all the Southern Provinces of Nigeria, chiefly as a planted tree in the neighbourhood of villages, and on the sides of the roads leading to them, being more prevalent in the Benin and Oban than the other districts. It is a medium-sized tree, reaching a girth of about 7 feet and a height of about 70 feet.

The gum, which exudes when the tree is cut with a matchet, smells very much like incense when burnt, and is of a white colour. It is always planted in the villages, partly for shade, chiefly for food, especially in the Oban country.

The fruit is first of all a grey, and then a purple colour, and a very cylindrical plum shape, in all about 2½ inches long and rather more than 1 inch in diameter. It is very much like turpentine to taste, especially when not quite ripe, and in the centre of the fruit there is an oblong nut rather more than 1 inch in length, more or less round, with four ribbed edges, all culminating at the apex. The leaves are large, consisting of four to six pairs of pinnæ, which are shiny and dark-green on the upper surface, and almost silver-grey underneath. The trunk is often very much cut about and chipped, and little pieces of the white gum are often seen in the old scars. It usually bears fruit heavily every year.

The sapwood is white and the heartwood is of a faint pink colour. It is not very hard, but more like mahogany in texture and character. Owing to its irregular growth and branching habit, it is often rather knotty and cross-grained.

It is a shade-bearing, somewhat slow-growing tree, which only partially protects the soil, but on the whole improves it with its fall of leaves. Natural regeneration appears to be rare, chiefly perhaps owing to the fact that the natives pick the fruit even before it is quite ripe, and take it away to eat in their houses. It is usually planted by the natives as a transplanted seedling, about 3 feet high. Considering the poor flavour of the fruit, it is rather surprising that it is so widely planted and comparatively speaking so much tended by the natives in certain districts. It is moderately fire-resisting and dew-collecting, especially in the dry seasons, the ground in the vicinity of the trees often being quite damp with the condensed dew falling off the leaves.

It has not been felled for export or for local use. The tree, however, provides grateful shade in the more open parts of the country, in the neighbourhood of villages.

The gum has not been collected for export, but is considered of value. However, no tapping experiments have been tried.

Native Use.—The fruit is called a pear, and is liked by most natives, who eat it raw. It is sometimes sold in the markets at five for one penny.

Canarium Schweinfurthii. Pink Mahogany, Bastard Mahogany. (Sometimes sold as Gaboon Mahogany or African Elemi. Anikantuhu, Ako, Ibagbo (Yoruba); Onumukyukyu (Benin); also known as Ikwapbo. (The Benin name means Kyukyu or bird, Onumu or Incense-tree.)

Chief Characteristics.—Evenly striated bark of orange to light-yellow colour, turning grey on exposure to full rays of the sun. The seed is small and similar to that of Pachylobus edulis, but much smaller.

Distribution.—A few in the Western, more in the Central west and south of Benin, and most common in the Eastern Circle, especially north of Calabar, in the mixed deciduous forest zone, and to lesser extent in the evergreen forest zone.

It is a large forest tree, with a girth of over 12 feet and a bole length of about 90 feet. Being more or less preserved by the natives when found in the forests, in clearing for their farms, it is often now seen on the roadsides. The slash is white, and as the roots beside the road are often cut by the natives, the yellowish-white gum exudes, forming a small white layer on the surface of the root. This has a most pleasant smell, and is not unpleasant to taste. It is closely allied to, if not much the same character as, the “Balsam of Tolu.” The leaf is comparatively small, with three or four pairs of pinnæ, and growing more or less in tufts, this being reminiscent of the Mahogany family. The root spurns are very slight, and in this respect it is more like the European Ash, and usually there are one or two main roots which spread out, down the slightly enlarged bole at the base. Otherwise the tree is one of the most cylindrical in shape, falling away with the increasing height less than almost any other. It is a deciduous tree. The pores are very fine and rather longer than in the ordinary mahogany, and the wood is not so sheeny.

The sapwood is white, and in fast-grown trees often 6 inches through. The heartwood is of a delicately pink mahogany colour, darkening to a light-brown mahogany on exposure to the air and sunlight. It is not very hard, and splits fairly well. It planes up with a smooth surface. It saws well and also takes nails fairly well. It has very considerable elasticity. It is lighter than most kinds of mahogany. The logs will float as soon as at all dry.

In youth it stands a good deal of shade, but later on it is on the whole a light-demanding tree. It is a fairly quick-growing tree, but tends to become very slow when left alone in the open. It needs a rich soil, but is also found on poorer land. It needs more moisture than many others. Although not a soil-protecting tree, the leaves yield a fair amount of humus in their annual fall. Natural regeneration is fair, but it is rather susceptible to fire, and much of it is thus killed. No plantations have been made of this tree.

In 1906 a sample was sold in the Liverpool market as Gaboon Mahogany at 1s. 6d. per cubic foot full measure, and in 1907 sample logs of this tree were exported to the Liverpool market, where they were sold as light Benin Mahogany at 2d. per superficial foot. Since then none has been felled.

The natives occasionally cut the tree for planks, and use the wood for making canoes, chiefly owing to its lightness and elasticity.

Canarium sp. Rough-barked Canarium. Ekugbi, Ekugbo (Yoruba); Onumukyukyu (Benin).

Chief Characteristics.—A large tree, with larger fissures than C. Schweinfurthii, about 6 inches apart; the bark is inclined to scale off in between. The leaves are a little larger, but the gum is very similar and used for similar purposes.

Distribution.—It was found in the Olokemeji Forest Reserve.

It is deciduous for about three weeks in the year, chiefly November, but otherwise it is a soil-protecting and soil-improving tree.

The tree has not been felled for export or for local use. Nor do the natives appear to have used it for any purpose.

Canarium Mansfeldii. Gaboon Mahogany.

This species is found on the banks of the Upper Cross River.

Canarium sp. Oyife (Yoruba).

Found in the Yoruba country.

Canarium sp., syn. Schweinfurthii. Incense Tree. Anikantuku (Yoruba); Onumukyukyu (Benin).

Found in the Ilaro district and Benin.

Meliaceæ.

Carapa procera. Scented Mahogany Cedar, Crab Wood, Touloucouna Oil. Efu Iya, Abo-oganwo (Yoruba); Ibbegogo (Benin).

It is a common tree, found in the Calabar, Ogoja, Owerri, Warri, Benin, Ondo and Abeokuta provinces of Nigeria.

It is a small tree, growing to a girth of about 6 feet. The pinnæ and the whole leaf are both much larger than the mahogany leaf, even including that of grandifolia. It often grows with a divided bole, two small stems shooting upwards from about 3 feet from the ground. The leaves grow in very distinct tufts on the edge of the branches. The bark is smooth and a light-green colour, with a few vertical uprights when the tree is old. The fruit is a large, roughly round, woody drupe. The covering shell dehisces into eight parts, releasing about twenty hard, brown, round-cornered, almost square nuts. The seeds are eaten by porcupines. It is found in the freshwater swamps in the evergreen forest and in damp places of the mixed deciduous forest. The timber is pink when freshly cut, and the heartwood has the red-brown typical of the Mahogany family. The small size of the timber rather militates against its reaching the high value of mahogany.

The tree is a shade-bearer in its younger stages of growth, and even when older it still stands a considerable amount of shade. Self-sown seedlings are not often seen. Perhaps this is due to so many of the seeds being eaten by animals. The stump scarcely sprouts after it has been freshly cut. Considering the size of the tree, a very fair number of nuts ripen each year.

No use has been made of the seeds, though they yield a similar oil to that of the Crab Oil Tree of South America.

In 1906 a sample of the timber was sold in the Liverpool market as Mahogany Cedar, scented, at 2½d. and 3½d. per superficial foot.

Native Use.—The bark is used by pregnant Yoruba women and for sores and as a cough mixture. It is used underneath palm leaves as a roofing material in the Benin country.

Khaya grandifolia, later grandis (Stapf.). Big-leaf Mahogany, Benin Mahogany. Akor, Oganwo (Yoruba); Gadeau, Ogwangu (Benin); Odala (Ibo Asaba); Digiten (Brass); Dirinshi, Diki (Ibo Owerri); Asamogo (Ibibio); Upono (Efik); Obon (?) (Oban, Ekoi).

It is found in the Ondo, Benin and Ogoja provinces of Nigeria, at the edge of the mixed deciduous forest zone, where it is very prevalent in some places, such as at the edge of the Ifon Owo-Akure Road.

Chief Characteristics.—It is a large tree of the mixed forests. It attains a girth of 14 feet and a corresponding height. It is, however, taller in proportion than K. Punchii. It has long, upward-tending root flanges, though not so large as those of K. Ivoriensis or the Coast Mahogany. The crown is open compared to the other Khayas, except K. Senegalensis. It has conspicuously large pinnate leaves, with three or four pairs of leaflets quite 10 inches in length, each leaflet being 4 inches long. The stem is smoother than K. Punchii, and in that respect more like K. anthoteka. The leaves of this species are the most shiny of all; in fact, the others appear dull beside them. The bole, on the whole, is cleaner than K. Punchii and longer, though it forks or divides into a head in the characteristic Mahogany way. The shininess of the leaves is one of the greatest characteristics of this tree. The capsule is somewhat larger than K. Punchii. It is also a little thicker, and the tip is not so long or sharp. It opens out into five segments, as a rule, but sometimes there may be only four. The seeds themselves are a little oblong in shape and not quite so square as in K. Punchii, although they are just as thin and flat.

The timber is the typical Benin Mahogany, with somewhat long pores, first of all rather pink, then a rich mahogany-brown colour. Occasionally the sapwood is very wide in proportion to the size of the tree, but this is more in the case of very quickly grown trees. It sometimes shows very rich figure of a “roey” nature as well as “fiddleback,” more especially in the root buttresses. Here, owing to the storms to which the tree is exposed, the fibres of these buttresses become fractured and compressed, thus giving a broken and mottled appearance to the grain after it has been cut up lengthways. In this species the wood of the “curls” often shows a rather bolder roe than in the case of those obtained from K. Punchii or Ivoriensis.

On the whole this is the most quickly growing of all the Khayas. In its youth it stands a certain amount of shade, and, in fact, always, but it would appear to demand a good deal of light for its full and quick development. It is a thoroughly soil-protecting and soil-improving tree. The leaves make a rich humus. Natural regeneration is good, and, in fact, appears to be much better than in the case of the other Khayas. It sprouts from the stump a little. It appears to be somewhat exacting as to soil, preferring somewhat deep, rich and moist sites. In plantations it has already found a place. It has also been planted, mixed with other species of Khaya, in the small nurseries, plantations and lines of trees made by the timber-lease holders. It does not seem to be attacked so severely by the leading-shoot borer as in the case of K. Punchii. Owing to the fact that the seeds usually fall on more open ground, it is not eaten so quickly by the little boring insects.

The timber is being constantly exported and mixed up with the other species of Khaya. Being lighter, it floats higher on the water than the other species, more especially Entandrophragma. It has occasionally been used by the natives for making canoes, as also for sawing up into planks.

Khaya Punchii. Uhi Mahogany, Benin Mahogany. Oganwo (Yoruba); Ogwangu (Benin); Eggi (Ibo Asaba).

This tree does not attain such a large size as either K. grandis or K. Ivoriensis, but it often exceeds a girth of 12 feet and a bole length of 70 feet. The bottom log of a tree is often found to show figured wood. This is perhaps owing to the bark being constantly removed, and to the succeeding occlusion of the wounds following at different times, according to when the bark is removed.

Chief Characteristics.—It has a comparatively small leaf, with five or six pairs of leaflets. It has slight root spurns, or protuberances, or even in some cases none at all. It is generally particularly rough at the base, owing to the bark having been continually removed by the local people. Higher up, the stem is covered with brown-coloured bark, which is slightly pitted. The leaves are in tufts, though to a lesser extent than either K. grandis or Ivoriensis. The large masses of small white flowers remind one of lilac. It is of the same white colour. It flowers in February, when it is also in new leaf. Compared with K. grandis it usually has a shorter and somewhat more curved bole.

Distribution.—It is found in the Abeokuta, Ibadan and Benin provinces of Nigeria.

The capsule is of medium size, splitting open into five segments which remain attached at the base. On the whole it is rather thinner than K. grandis or Ivoriensis, but does not come to such a sharp point as either of those two.

The timber is very similar in grain and texture to the other Khayas, but if anything it is a little heavier and a little closer texture then either grandis or Ivoriensis, especially in those districts where it grows in the mixed deciduous forests, and where the base of the trunk is burnt with an occasional grass-fire.

Although not quite so fast-growing as the other Khayas, it is a fast-growing tree with soil-protecting and soil-improving qualities. Natural regeneration is fair, though the little thin, flat seeds are very soon attacked by a little boring insect when they fall to the ground. However, when rapidly gathered after having fallen, they retain their germinative capacity for a greater length of time than in the case of the Entandrophragmas. On the whole, if the locality is not too dry or fires too prevalent, this tree tends to widen its area of distribution with the spread of farms. The leading-shoot borer attacks this tree in its younger stages perhaps even more than the other Khayas, more especially when it is planted pure. In this connection it should be noted that this Khaya, as well as the others, is not gregarious in habit, being always found singly, though varying much in number per square mile. This factor rather indicates that pure plantations should not be made, or at any rate that it should only be planted in small groups mixed with other species, also in small groups, from a quarter to one acre in extent. In leased timber areas it has been planted mixed with other species. On the whole, it has not been exported so much as the other Khayas. It has been sold as Niger Mahogany.

Value.—3d. to 6d. per superficial foot from Sapoba, in the Benin province. The natives occasionally cut it for sawing into planks.

Khaya anthotheca?. White-barked Mahogany or White Mahogany, King of the Timber. Funfun (Yoruba); Ogwangu Nufwa, Ogigedu (Benin).

Many specimens of this tree are found in the mixed forests on the banks of the Ovia River in the Ifon district of the Benin province, and also isolated trees near the banks of the Owena River in the Ondo province.

The chief characteristic of this tree is the speckled white bark, which gives the stem generally a light, almost white or grey colour. The white patches in the bark occur irregularly scattered all round the bole, being chiefly confined to the lower half of it. In young trees the four very strong lateral roots show up prominently above the ground, leading away from the tree more or less at right angles and remaining above the surface of the ground for two or three feet. This feature to some extent persists even in old age, but then it is not so pronounced, as these roots tend to form more or less stout buttresses similar to the others, but coming out more abruptly and forming a more shelf-like protuberance from the stem.

The timber is supposed to be lighter, and of a lighter colour than that of the other Khayas. However, it appears to be only rather more of a pinkish-brown when freshly cut, taking on the typical mahogany-brown once it is exposed to the air. So far, it has always been sold mixed up with the other species cut in the same area, and realizes similar prices. It may perhaps have even helped towards the scoring of the higher average price of 6d. per superficial foot which was obtained from one area where this species is found.

Khaya n. sp. Mahogany. Ogwangu (Benin).

This was found in the Benin province of Nigeria. In the wood, it shows a considerable difference to the other Khayas, being a much lighter red-brown colour and of more open texture.

Khaya Ivoriensis. Coast Mahogany. Obi, Oganwo, Akpakor (Yoruba).

This species is supposed to be that from which most of the coastal mahogany is obtained, more especially in the more low-lying regions. The wood is of a richer and darker colour and somewhat heavier than that of the other species. The most typical feature, though, is the very sheeny nature of the wood and the very considerable size of the medullary rays, which, however, are not conspicuous, as in the wood from Nigeria.

Khaya Senegalensis. Dry-zone Mahogany. Oganwo (Yoruba); Ogwangu (Benin).

Chief Characteristics.—The tree has an open crown with a few upspreading branches, and apparently much less foliage than its “confrères.” The leaves are small, very grey, specially on the under-surface, giving them almost the character of Eucalyptus leaves. The bole is shorter than the other Khayas, with a slightly scaly bark and only a small thickening of the base and no root buttresses at all. The bark is darker than Khaya Punchii, though the scales are often grey. The capsule is almost frequently four-sectioned, though this is not an absolute rule, as other Khayas have been found bearing capsules dividing into three, four and five sections. It does not exude gum so readily as Khaya Punchii, and the gum is of a redder colour. Illustration No. 67 shows the lower part of the bole of a tree 10 feet in girth.

Distribution.—It grows on the banks of the Ogun River above the Iseyin-Oyo Road, Ibadan province, Akure, Benin and Ogoja provinces of Nigeria. It is found as one of the most prevalent trees near Obudu and in the Onitsha province north of Ogrugu.

Timber.—It is of redder brown colour than either Khaya Punchii or grandis, and has a greater sheen. The texture of wood is a little closer, and, owing to the annual grass-fires burning the stem, is slightly figured. Logs could not be cut much more than 20 feet in length, owing to the bole not always being straight, though the large branches would make small ones and curls.

Silvicultural Qualities.—It stands a great deal of drought, though in its drier area of distribution it is usually to be found near river banks. The seed keeps a high percentage of germination for some months after being picked. It demands more light than either of the other Khayas, and grows freely from the beginning. It has also a greater tendency to branch than the other Khayas, but this may be due to its being attacked more by the leading-shoot borer than the other species, as more of these insects are found in the open than in the mixed forests. It is almost gregarious, as groups of trees are usually found together.

Khaya sp. Orro (Yoruba); Geduloha (Benin).

This tree is found in the Ilaro district of the Abeokuta province. There appears to be some doubt as to whether this is really a distinct species, but the fact remains that the wood is very much darker and of rather a duller colour than most of the other Khayas. It shows also a very rich, wide roe, and in this respect the wood is more valuable than that of many other species. It is somewhat similar to the best counter-top wood obtained from the Entandrophragmas. It does not appear to be a very common tree, but it attains a girth of over 12 feet, and the bole is straighter and considerably taller than most of the Khayas.

Pseudocedrela Kotschyii. Dry-zone Cedar. Hard Cedar Mahogany. Emi gbegeri (Yoruba, Ibadan).

It is found in groups and isolated specimens in the Ibadan province of Nigeria, in the dry-zone forest and at the edge of the mixed deciduous areas, more especially in the Olokemeji Forest. With its somewhat regularly fissured bark, showing a criss-cross pattern, it is distinguishable from the other dry-zone trees. The silvery pinnate leaves in tufts and the charred base of the stem, combined with the grey trunk, all help to identify it. The little mahogany-like capsule, covered with silvery hairs when unripe, is another feature. When these burst open, leaving the empty capsule on the tree for a time, there is no doubt about its being of the Mahogany family. In the distance the grey, almost silvery-coloured bark makes it stand out as compared to others such as Dwarf Ironwood or the Shea Butter Tree. Reaching a girth of about 6 feet and a bole length of 25 feet, it is one of the largest dry-zone trees.

The sapwood is pinkish-red, when fresh, and the heartwood a rich red-brown, darkening slightly on exposure to the light. It is harder than mahogany and heavier. The grain is closer and on the whole finer, but with a similar sheen. It often shows a little figure. It saws well, planes smoothly, takes nails, and has a good appearance in the plank. It is said to be termite-proof. It is considerably stronger than mahogany.

Somewhat slow-growing, even from naturally growing root suckers, it is a light-loving tree, giving scarcely enough shade to protect the soil. In its youth it is a soil-improving tree. Natural regeneration is poor, root suckers being the strongest form of reproduction. It sprouts slightly from the stump, but not sufficiently for reproduction of a crop. A fair crop of seeds is found each year, but usually, owing to grass-fires, much of this is destroyed. Plantations are being made, but natural growth has been encouraged in places, and gives further promise of better growth.

It has not been exported, but it is occasionally felled for local use. It is one of the most valuable trees of the dry zone.

Entandrophragma utilis. Short-capsuled Mahogany, Sapeli or Heavy Mahogany. Ijebbo, Jebu, Ashuwole, Papala (Yoruba); Ogipogo, Ubilesan Onamakyuku, Plekkogo (Benin); Eplekgo (Jekri); Edem (Efik); Atori (Oban, Ekoi).

This tree is found in the evergreen and mixed forests of the Ondo, Benin, Calabar and Ogoja provinces of Nigeria. It is one of the most common mahoganies of the forest, and reaches the largest girth of any of the African trees. The biggest of all showed a girth of 56 feet, measured above the top of the buttresses, and one which showed 437 rings of growth had a girth of 52 feet, measured at 20 feet above the ground. This one, too, yielded 15 logs of various sizes.

The leaves are rather smaller and show the ribs rather more prominently than in E. cylindrica, but the growth, which is in tufts, is similar. It is deciduous for about three weeks in the year, in November, when inconspicuous flowers first appear and then the leaves. The capsule is about 3 inches long and nearly 1 inch in diameter. It is of the usual pentagonal shape, and there are five seeds, placed one over the other on each side of the central pentagonal core. The seeds are nearly square in shape, with a rounded back about an eighth of an inch thick. The wings are four times the length of the seed, making each about 2½ inches long. The seeds lose their germinative power in about three weeks, and are always attacked by a small boring insect.

The bole has comparatively slight root spurns, which terminate at about a maximum height of 20 feet from the ground. It is very straight, and may attain a height of 90 feet. The stem is, however, much more pitted than that of E. cylindrica. The bark is of a green to grey colour, very reminiscent at times of a beech-tree, especially at a distance. The crown is flatly spherical, being composed of a few very large limbs. The slash is white and brown; the sapwood is white and the heartwood of a red-brown colour, with a very strong cedar-wood scent when freshly cut. Even when the wood is seasoned and freshly planed, this scent is very noticeable. It saws and splits easily, planes up moderately, and takes nails fairly easily. It is not termite-proof, but the most common attack is by a lymexylon, if the logs are left lying unsquared in the forests. Many figured logs have been obtained from this species of tree. In the younger stages, the sapwood is comparatively wide. Natural regeneration is very good in some places. The tree grows very rapidly indeed. In its youth it stands a certain amount of shade, but later on it is a light-loving tree. It is a soil-protecting and soil-improving tree. Isolated trees have been planted and small plantations made in various parts of the country. Planted under proper conditions and with favourable seasons, an average growth of 6 feet in height may be expected. The young trees are occasionally attacked by the leading-shoot borer, but this is not very serious, particularly if a suitable mixture with other trees has been formed.

This timber has been one of the main export products of the Sapeli and South Benin forests. The chief market for this wood was, previous to the war, in Hamburg. However, from Hamburg, the markets of Copenhagen, Sweden, Finland, Russia and Austria were also supplied. Being almost half as heavy again as Khaya Mahogany, it costs more in proportion to bring over to Europe. Owing to the better and larger size of the logs which can be obtained from these huge trees, there was in these markets a greater demand for this timber for counter-tops than for Khaya timber. This to some extent counterbalanced the disadvantage of the extra weight. This timber was also considered of a duller colour and more liable to split than the Khaya wood. However, as many of the trees from which the largest logs have been obtained are mature, and over-mature, it is natural that the wood cannot be in a prime condition.

The timber is very popular amongst the local people for the making of canoes and for house-building.

Entandrophragma cylindrica. Heavy Mahogany or Cedar Mahogany. Jebu, Oro, Issisi, Alepo, Alopa (Yoruba); Ikwabobo, Agiekpogo (Benin); Atore (Efik).

It is found in the Abeokuta, Oyo, Ondo, Benin, Calabar and Ogoja provinces of Nigeria. It is one of the common mahogany-trees of the evergreen and mixed deciduous forest zone. It is the tallest of all African trees, the bole alone often attaining a height exceeding 100 feet. It is also one of the straightest and most cylindrical trees in Africa. The root spurns are very slight compared to the size of the tree, and do not extend usually more than 10 feet up the stem. The bark is smooth and not unlike the beech; in old age, however, it becomes slightly pitted and the bark scales off in places. The crown is deeper and more spherical than in the case of Entandrophragma utilis. The ends of the branches are most conspicuous, with their most pronounced tufts of leaves. The leaf is often about 4 inches long, but in young shoots may attain a length of nearly 3 feet, with over thirty pairs of pinnæ. The slash is white, with small, yellow, stone-like granules in it. The bark is thick.

The capsule is nearly 6 inches long and an inch in diameter. It is similar in shape to that of Entandrophragma utilis, and opens in a similar way. The seeds are rather larger and the wings considerably longer. It is deciduous for about a week in November, when the flowers, which are of a light-greenish colour, appear, and then the leaves.

The sapwood is white and comparatively wide, except in very old trees. The wood, when freshly cut, smells slightly like a red herring, and in colour is not unlike the flesh of kippered herring.

The heartwood is of a red-brown colour, rather dulling on exposure to the air and becoming a dark-brown colour. The pores are very long, much more so than either in the E. utilis or the Khaya genus. The timber splits well, saws easily, and takes nails moderately well. It is not always easy to plane it down to a smooth surface. It has a distinct tendency to warp unless properly seasoned. It is not termite-proof, but the attacks of the white ants are slow. The sapwood is more commonly attacked by a lymexylon. For interior work it is very durable; sometimes it has a very pretty, dull-brown wavy sheen.

Natural regeneration is good in many places. Isolated trees have been planted and small plantations made in different parts of the country. The growth on the whole is even more rapid than in the case of E. utilis. In favourable localities it will exceed an annual height growth of 7 feet. Although it will stand a considerable amount of shade in its youth, it is more of a light-loving tree in old age. It is a soil-protecting and soil-improving tree.

This is one of the chief mahoganies exported from the Benin and Sapeli forests, but it does not attain such an average high price as that of the Khaya genus. However, from all accounts it appears that the majority of figured logs have been obtained from this species; this compensates to some extent the disadvantage of this being the heaviest wood of all the mahoganies. It often floats just level with the water, and has sometimes been known to sink. In pre-war days it used to fetch 4d. per superficial foot, and the best market for it was in Hamburg; but, as also in the case of E. utilis, the wood was supplied to the markets in Austria, Russia, etc. It is common to make three logs each 30 feet long from the bole. Both this tree and E. utilis yield some of the best curls which are obtained from the mahogany.

The local people used to be very fond of using this tree for making canoes, and I have seen a canoe over 80 feet long and having a draught of over 6 feet. It has also been largely used in house-building.

Lovoa Klaineana. African Walnut. Abuwe (Yoruba); Ikwahobo, or usually known amongst the timber men and forest officers as Anamomilla in Benin, Apobo (Jekri, Ijor).

It is one of the most prevalent trees on the banks of the Ogba stream in the Benin province, and it is also found in the Ondo, Abeokuta, Owerri and Calabar provinces of Nigeria.

This tree grows to a large size, reaching a girth of over 12 feet and a bole length of over 60 feet. The root spurns are slight compared to Mahogany, extending only from 4 to 6 feet up the stem.

Chief Characteristics.—The small, almost quadrangular-shaped capsule, which splits open with four sides and centre square in section with only eight seeds, two placed on each face, is about the size of a little finger. At its base the bole is not entirely circular in shape, but tends to form four distinct narrow small buttresses, giving it almost a quadrangular shape. The bark is a dark brown colour, which gets rougher with old age and scales off to a small extent. Compared to the size of the tree it is not very thick. In the younger trees it is quite smooth and more of a yellow-brown colour. The leaves are pinnate, with three or four pairs of pinnæ. The four-sided capsule is a most typical feature of this tree, and distinguishes it from Entandrophragma. The leaves are of a dark colour.

The sapwood is white and the heartwood is a good walnut-brown, sometimes with very striking dark-brown or black streaks in it. The sapwood is comparatively narrow and the heartwood forms comparatively early in the life of the tree. The wood is only moderately hard; it planes well, and takes nails; it saws easily, and splits moderately well. It is, however, attacked by termites, but not when used for interior work. It shrinks but little and does not warp very much. The grain is rather finer than that of the ordinary mahogany, but the pores are often much longer. It has a pleasant lustre, but tends to darken a little with age, especially when not exposed to the brightest light. The tree is a moderately fast-growing, shade-bearing species, with soil-protecting and soil-improving qualities. Natural regeneration appears to be moderate. It sprouts slightly from the stump. Seed years are none too frequent. The seeds themselves are soon eaten by boring insects when they lie on the ground; even when picked up they soon lose their germinative capacity, and should be planted within a month of being gathered, as they are so liable to get dry. The tree is a little exacting in regard to soil, apparently demanding plenty of moisture, depth and a good deal of humus. No plantations have been made with this tree, but a great number of isolated trees have been planted by timber-lease holders in their areas.

In 1906 samples of this timber were sold in the Liverpool market as African Walnut at 1d. per superficial foot. Since then, however, the qualities of this timber have become better known, and it now finds a ready sale at rates varying from 2d. to 5d. per superficial foot. Although it is a mahogany by family, it is usual to sell it as African Walnut, as the colour and texture of the wood are very similar to walnut.

Native Use.—In the Benin province it has been used for canoe-making.

Guarea Thompsonii. Cedar Mahogany, Cedar or Close-grained Mahogany. Sidu (Yoruba); Obobonikwi (Benin); Akpaku (Ibo Asaba).

It is a large forest tree of the evergreen forest zone, attaining a girth of 12 feet, which is most commonly found in the Benin district of Nigeria.

Chief Characteristics.—The trunk is dark-brown with smoothish bark, which has a tendency to scale off a little. The pinnate leaves are shiny and form very distinctive tufts at the ends of the branches, though not quite so much as in Entandrophragma.

The fruit, which is quite soft, is a dehiscent capsule, of a dark brown colour; when ripe, three black seeds covered with red pulp are released. The seeds are ellipsoid in shape and smaller than those of G. sp., Obobonufwa. The seed is nearly half an inch long and covered with white streaks following round its narrowest circumference. The crown is very thick and dense compared with G. sp., Obobonufwa. The bole length is shorter, and the shape of it is not so regular nor so round as that of G. sp., Obobonufwa. The crown is flatly spherical in shape, reaching fully a third of the total height of the tree. The flowers are yellow and borne in long spikes about 1 foot in length.

The sapwood is white and the heart of a mahogany-brown colour, with a slightish red tinge when freshly cut, which rapidly goes a light brown colour, though not such a light brown as in the case of G. sp., Obobonufwa. It has a strong cedar scent when freshly cut, and even the old wood retains this scent when planed up afresh. The grain is fine, though a little fibrous. The pores are long and open. It has, however, a nice sheen, giving a better appearance than that of G. sp., Obobonufwa. It planes easily, but does not split very well. It takes nails fairly easily and saws without difficulty. It is not termite-proof. It has considerable tensile strength and elasticity. In proportion the heartwood is very large and forms comparatively early in the life of the tree. It has a closer grain than any of the mahogany of the Benin district.

The tree is a fast-growing one, at first shade-bearing, and later a more light-demanding species, with soil-improving and soil-protecting qualities. Natural regeneration appears to be fair, though the seeds are eaten by insects, and they do not appear to keep their generative capacity for a great length of time. It appears to be rather exacting as to soil, liking one with a fair degree of moisture, mineral content and of considerable depth. No plantations have yet been made of this tree, but isolated specimens have been planted by the timber-lease holders. It bears good crops of seed every few years.

Owing to the comparative shortage of mahogany trees on some areas, this tree is now felled as a timber for export, and is sold as Scented Mahogany at 3d. to 6d. per superficial foot. Locally it has been cut for planks.

Guarea sp. Cedar Mahogany, Scented Mahogany. Sida, Sendar, Odogbo, Akokogbo (Yoruba); Obobonufwa (Benin); Akpaku (Ibo Asaba).

It is a large forest tree of the evergreen zone, attaining a girth of over 12 feet, which is most commonly met with in the Benin district of Nigeria.

Chief Characteristics.—The bole is covered with smooth grey bark, which peels off very gradually in large pieces more like a plane; it is sometimes relieved by patches of yellow or red lichens. It has tufts of pinnate leaves at the end of the branches.

The fruit is a greyish-brown coloured, dehiscent capsule, which contains three large seeds covered with orange-coloured flesh. The seed is black, and wider and thicker than the G. Thompsonii, though the length is about the same; this makes it flatly ovate. The seed is covered with white streaks in the same way as Guarea Thompsonii. The root spurns are narrow and extend further up the stem than in the case of G. Thompsonii, though in the younger trees the stem is very cylindrical. The silvery-coloured bark is most typical of this tree, thus distinguishing it most clearly from G. Thompsonii. It is very similar in appearance to Sideroxylon Aylmeri of Sierra Leone, so that indeed it may be a species of Sideroxylon, or even the same.

It is found in the Ondo, Abeokuta and Benin provinces of Nigeria.

The sapwood is white and narrow and the heartwood light-brown, rapidly darkening to a more mahogany brown. When freshly cut it has a strong cedar scent, which goes off to a certain extent when it is dry, but on planing the wood up again there is always a slight cedar scent. It is closer grained than G. Thompsonii, but it has not so much sheen. On the whole the colour is poorer. It is not considered quite so durable as G. Thompsonii, nor is it termite-proof. It planes well and saws easily, splits moderately well, and takes nails without difficulty. It is of a very light colour for mahogany. It has a good, mellow texture.

It is at first slightly shade-bearing, but later a light-demanding tree. It grows comparatively rapidly. It thoroughly protects the soil and enriches it with its leaf fall. Natural regeneration appears to be only moderate, perhaps owing to the fact that the seeds soon lose their germinative capacity or are eaten by animals. It appears to be somewhat exacting as to soil, liking one with considerable depth, mineral content and a fair degree of moisture.

In 1906 sample logs of this timber were considered of a lower value than mahogany, and were sold as Scented Mahogany at 3½d. to 3¾d. per superficial foot. Since that date the timber has been regularly shipped from the Benin district and sold as Scented Mahogany, and it is usually worth from 2½d. to 6d. per superficial foot. Owing to the comparative scarcity of large girth mahoganies (Khaya sp.) in some localities, it is being felled in increasingly large quantities.

Trichilia Heudelottii. Rere, Ako Irere, Asana (Yoruba); Ovallo (Benin).

It is found in the Abeokuta and Benin provinces of Nigeria.

It has a smaller leaf than Trichilia sp., and is rather a smaller tree than T. Prieuriana. The heartwood is brown-red and very hard; the sapwood is white.

It is a slow-growing, shade-bearing, soil-protecting and soil-improving tree of the mixed forest zone.

Occasionally it is used as a house-building timber, when there is nothing else available.

Trichilia sp. Iseko (Yoruba); Ogiovalo (Benin).

It has a larger leaf than T. Heudelotii. It is found in the Abeokuta, Ondo and Benin provinces of Nigeria. The heartwood is brownish-red and the sapwood is white. It reaches rather a larger size than T. Heudelotii, attaining a bole length of about 15 feet and a girth of 5 feet. The seeds are very similar to those of P. Prieuriana. It is termite-proof.

It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration appears to be slight. It apparently demands a good soil, and is found in the mixed deciduous forest.

It has not yet been tried as an export timber, but it might be useful as a hard mahogany, both for export and for local use.

Amongst the natives it is occasionally used as a house-building timber, the tree having a fork at a convenient distance from the ground.

Trichilia Prieuriana. Awe, Eriagbo (Yoruba); Igogo (Benin); Somabari (Oban, Ekoi).

Chief Characteristics.—It is a dark-foliaged tree, usually found dominated in the mixed forest, with thin, scaly bark and thin, long leaves, with four or five pairs of pinnæ. The seeds are reminiscent of Guarea.

Distribution.—It is found in the mixed deciduous forests of the Abeokuta, Ibadan and Benin provinces of Nigeria.

Timber.—It has a hard, red heartwood of close grain and white sapwood; it does not shrink nor warp to any extent.

It is a slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration appears to be poor, perhaps owing to the fact that the seeds decay very rapidly when lying in the ground.

In the dry season the dew condenses very readily on this tree, and thus makes the ground very moist underneath.

It does not reach really export timber size. It has not been used either for export or locally. However, for smaller constructional work it deserves a trial.

Turræa Vogelii. Asha omode (Yoruba); Ovioza (Benin).

It is rather an uncommon tree of the Benin province of Nigeria. It is quite small, only attaining a girth of about 2 feet. It usually stands in the shade as part of the undergrowth of the evergreen forest.

The natives have no particular use for it.

Turræa heterophylla.

This tree is found in the Abeokuta province of Nigeria. It is a small tree which has been specially noticed in the Ilaro Forest Reserve. The Yorubas do not have any special use for this species of Meliaceæ. It is considerably harder than either mahogany or cedar mahogany.

Ekebergia Senegalensis (Juss.).

It is a medium-sized tree found in the Abeokuta province of Nigeria. It is distinguished by its white flowers, and is found growing in the Olokemeji Arboretum. The leaves are large for Meliaceæ, but the position of the flower-stalk and the bark are typical of this family. The natives have not used the wood thus far. It would make rather an ornamental shrub-like tree in a garden.

Melia Azedarach. Bead Tree or Persian Lilac. Eke Oyinbo (Yoruba).

A tree found growing plentifully. It is of medium size, bearing a very ornamental flower. It yields timber, gum, oil and medicaments, and is also used in the preparation of liquors. The fruit is poisonous.

? Mahogany. Onyemo (Benin).

This tree is somewhat uncommon in the Benin province of Nigeria. It is closely allied to the African Walnut. It is apparently a mahogany, so far as the texture of the timber is concerned, and the grain is very similar too. It is a medium-sized tree with a bark less pitted than that of the Entandrophragmas and with a more greenish tinge. The slash is white, the sapwood whitish-yellow and the heartwood light-brown, becoming darker on exposure to the air. It has occasionally been cut in Benin and used as mahogany.

Polygalaceæ.

Carpolobia lutea (Don). Oshunshun (Yoruba).

It is found in the Abeokuta and Benin provinces of Nigeria. A shrub-like tree.

Polygala arenaria. Okuturupu (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Dichapetalaceæ.

Chailletia floribunda (Planch). Kukumarugbo (Yoruba).

This is a small tree of the mixed deciduous forest zone. It is a shade-bearing and soil-protecting tree.

The timber is hard and durable. Locally it has not been used to any extent, though it might find a place in temporary buildings as verandah-posts or window-frames. The timber is said to be termite-proof. The flowers are very conspicuous and quite enliven the forest with their bright colours.

Euphorbiaceæ.

Ricinodendron Africanus. African Wood Oil Nut. Erimado, Ekku (Ib.); Funfun Puttuputtu (Yoruba); Okkwen, Okwen-seva (Benin).

It is a large or more often medium-sized tree with smooth grey bark, rather thin branches in more or less whorls, and open crown. The fruit has two lobes, with one seed in each lobe. The leaf is digitate, with a varying number of digits, from three to five. The leaves are rather smaller and much thinner and finer in texture than those of R. Rautenii. The root spurns are smaller, and do not appear much more than 1 foot to 2 feet above the ground, nor do the roots themselves usually extend above the ground. It reaches a girth of about 8 feet.

To face p. 332.

The timber is a little more closely grained than that of R. Rautenii, but otherwise very similar. On the whole the bole has a less good shape, tapering rather more in proportion to its height. The timber length of the tree does not usually exceed 25 feet. Natural regeneration is very good, though this tree does not bear seed so heavily as the sister species. It sprouts well from the stump, but the stump does not last. In its youth it will stand a little shade, but is really a light-loving tree, with soil-protecting, soil-improving qualities. It is not quite so rapid a growing tree as R. Rautenii, even though it is one of the quickest growing trees. It appears to like a moist, comparatively rich soil.

In 1906 samples of this timber were sold in the Liverpool market as a species of mahogany. It is, however, probable that these were logs from a different kind of tree, as the wood is too dull a brown colour to be really like mahogany. Locally it has not been sawn up for planks, but deserves a trial as a box-making and pattern-making wood.

Native Use.—It is felled indiscriminately with R. Rautenii and used for a similar purpose.

Ricinodendron Rautenii. Yoruba Coffin Wood. Ekku, Puttuputtu (Yoruba); Okwen-seva, Okkwen nebo (Benin).

A large tree, up to 12 feet in girth, with stout branches and roughly fissured bark reminding one of oak. The fruit is slightly three-lobed, containing three seeds. The leaf is digitate, with the number of digits varying from five to seven. The leaves are larger and thicker and with a rougher surface than those of R. Africanus. The crown is thicker, more widespread, and roughly spherical in shape. The roots usually come out of the ground near the base of the tree and form rough root spurns, extending 3 or 4 feet up the bole of the tree. The bole reaches a length of 30 feet.

It is one of the commonest trees in the moist secondary forests and at the edge of the mixed deciduous forests in Benin, Abeokuta, Calabar.

The timber of this tree was described as a “species of mahogany” and suitable for the Liverpool market in 1906.

Native Use.—By the Yorubas it is cut down and sawn up into planks for making coffins. Mostly medium-sized trees are used for this purpose. None of the natives apparently know how to use the nuts.

Ricinodendron sp. Species of Mahogany. Okwen seni (Benin).

The African oil-nut, with four nuts in each fruit, appears to be the same, but this larger number of nuts is the specially distinguishing feature, and has been given a distinct name by the Benin people. It is, however, rather doubtful if it is really a different species from R. Rautenii.

Native Use.—It is used in much the same way as the other two species.

Uapaca Heudelotii. Mahogany. Yeye (Yoruba); Oyen (Benin); Ile (Bonny and New Calabar).

It is found in the Owerri and Yoruba provinces of Nigeria. With its slightly curved trunk and large mass of widespreading aerial roots, extending almost to a quarter up the height of the tree, it is distinguishable from other trees of this zone. Usually found growing near water, or in regions that are flooded periodically. It sends out fresh red-coloured aerial roots. The leaves are somewhat shiny and give a greyish appearance in the distance. The bark is finely fissured and dark brown. Often covered with moss at the base. It attains a girth of about 10 feet and a bole length of about 25 feet.

It is a somewhat slow-growing, shade-bearing tree. It protects the soil and enriches it with the fall of its leaves. Its mass of aerial roots tends to moderate the speed of the flooded river and holds the banks up, preventing corrosion, and in many cases tends to help the formation of higher and more solid banks, owing to the deposit of sand between and near the network of aerial roots.

The timber is very similar to mahogany in grain, though a little harder. It has considerable elasticity. It is finely fibrous, and does not plane up with such a smooth finish, nor does it split well. It is termite-resisting and moderately tough. It saws with difficulty. The sapwood is stained with reddish colouring matter, and the heartwood is a dull red-brown. The pores in the timber are longer, and resemble mahogany in this respect; though, being fibrous to the touch, the difference is shown.

The timber has not been exported, nor has it been sawn up for local use. Occasionally it is used by the natives for house-building, and some of the crooked roots and branches are used as ribs for boats and building up canoes.

Uapaca Guineensis (Muell. Arg.). False Mahogany. Abo Emido, also known as Yeye and Yere (Yoruba); Onye (Benin).

Chief Characteristics.—Large aerial roots supporting the bole at a height of 8 to 10 feet from the ground. When cut, the slash is red; the sapwood is whitish, tinged with the red colouring matter of the heartwood, which is a dull red.

Distribution.—Banks of the Ogun, Olokemeji Forest Reserve.

In most respects the timber is similar to that of Heudelottii. On the whole, however, this species is a little harder than the other.

This tree is somewhat slow-growing and stands less shade than the Heudelotii. It is of the greatest value, with its aerial roots, in protecting and increasing the height and stability of the river banks at the edge of the dry forest zone. It is one of the few trees that are not washed out of the banks in the flood season, and even when they do fall over into the river they remain attached to the bank and lessen the force of the current. Natural regeneration is none too good.

The timber has not been exported, nor has it been felled locally for conversion into planks. Occasionally the natives use the smaller trees for house-building. They also consider the places in the rivers immediately near or overhung by one of these trees as the best localities for fishing.

Bridelia micrantha. Yoruba Ironwood. Ira Odan, Asa Gidi (Yoruba).

It is found in the Ibadan and Abeokuta provinces of Nigeria.

It is a small tree or shrub up to 8 feet high, with a large alternate leaf. The bark tends to be fibrous and can be stripped off in a similar way to the other Bridelias.

The timber is very hard, moderately durable, and said to be termite-proof. Its small size and somewhat crooked nature hinders its more extensive use.

It is occasionally of use for house-poles in temporary buildings, and makes good firewood, giving intense heat. The leaves yield a rich humus and improve the soil.

Native Use.—The bark is mixed with Hausa salts and then drunk with lime and water as an aperient.

Bridelia Zenkeri, syn. atroviridis. Yoruba Ironwood. Asha, Asha ragha (Yoruba); Oviaruza, Assivi, Ogangan (Benin).

It is a comparatively common tree of the Abeokuta, Oyo, Benin and Owerri provinces of Nigeria. The roughly fissured bark, scaling off in criss-cross fashion, in papery or fibrous layers, is most typical of the tree. The bole is short, seldom reaching a greater length than 15 feet. It is usually forked about this height and then spreads out, rather reminiscently of the elm. It yields the hardest wood of all the African trees, except perhaps Okuta (the stone).

It is occasionally used for house-building by the natives.

Bridelia stenocarpa. Benin Ironwood. Arasha, Asha, Aroro Ashasha (Ondo), Aiveygbo (Eg.) (Yoruba); Assivi (Benin).

This tree is found in the Benin and Calabar provinces of Nigeria, where it is somewhat prevalent, but found always singly in the forest. In habit it is not at all unlike the wych elm. The leaf is of similar size and shape, the bark peels off in fibrous layers, but is otherwise fissured in lattice-work fashion. For the size of the tree the bark is comparatively thin; the slash is light-brown, sometimes a whitish-grey. The sapwood is white and the heartwood is dark-brown and very hard. It saws well, but is almost impossible to split, and it will not take nails. It has a short bole of about 20 feet, is deciduous for a few days in the year, but is otherwise a soil-protecting and soil-improving tree. Samples were at one time on the way to be exported, but were sunk by accident, the wood, of course, being much heavier than water.

The natives occasionally use it for house-building.

Excœcaria sp. Orupa (Yoruba).

It is a small tree, up to 18 inches in girth, with smooth, yellowish-red bark, and has maple-like seeds in pairs joined at the base. The stem gives a greyer impression than that of Ormosia laxiflora, and it is also much smoother.

Distribution.—It is found in the dry-zone forest of the Ibadan, Abeokuta and Onitsha provinces of Nigeria.

Timber.—Not very hard and of a yellowish colour.

Native Use.—The bark and roots are used medicinally. It is sold in the Lagos medicine market.

Antidesma venosum. Aroro (Yoruba).

It is a small tree, about 9 feet high. Found in the Olokemeji Reserve.

Antidesma sp. Ogbamaton (Benin).

Found in the Benin province.

Tragia Manniana. Esisi (Yoruba); Ogangan (Benin).

Found in the Ondo and Benin provinces.

Microdesmis puberula (Hook.). The Benin Apata Wood. Apata (Yoruba); Ehranpata, Esanpata, Omomeran (Benin).

It is found in the Abeokuta, Ibadan and Benin provinces of Nigeria.

It is a small tree with hard wood of a brown colour. It reaches about 15 feet high with a girth of about 12 inches.

On the whole this is a slow-growing, soil-protecting and soil-improving shrub. It serves a useful purpose in the undergrowth and is of local value as well.

Native Use.—The wood is used for making the musical instrument known to the Benin as Apata, a kind of harp-shaped frame made of wire, but much smaller.

Microdesmis sp. Essunsun, Ubelluname, Ubellunowe (Benin); Njorgora (Oban, Ekoi); Akiti (Ibo Owerri).

It is a common tree of the Benin, Ondo, Ogoja and Calabar provinces of Nigeria. A medium-sized tree of about 6 feet in girth, attaining a bole length of about 40 feet. Its small, pretty five-petalled flowers fall off the tree and cover the path or neighbouring bushes; their scent is very pleasant and is reminiscent of honey and flowers.

The sapwood is white and the heartwood light red brown, rather hard, of close grain and close texture; it planes moderately well, but it is rather hard to saw and does not split. It is durable under cover, but does not last when exposed to the weather. It hardens very considerably when exposed to the air. The timber was used for verandah-posts in the Calabar district, but did not prove very suitable, as a large borer often attacked it. The timber is not absolutely termite-proof. The natives occasionally use the wood for house-posts.

Phyllanthus reticulatus. Iranje (Yoruba).

Found in the Olokemeji Reserve.

Phyllanthus sp. Awe, Erigaba (Yoruba); Eghogho (Benin).

Found in the Olokemeji Reserve.

Cyclostemon. Oyen (Benin). This may be the same as Uapaca Heudelotii.

It is a medium-sized tree of the Abeokuta and Benin provinces of Nigeria. It has aerial roots and likes a damp, moist soil. It has red flowers which come out in February. It yields a hard, reddish wood, which is rather fibrous.

Manniophyton Africanum. Ebumen (Benin).

This is a small creeper similar to that known as Okwe by the Benis.

Manniophyton sp. Okwe (Benin).

This is a long creeper found in the Benin and Ogoja provinces of Nigeria.

The nut of this creeper is most commonly seen in the cooked state in the markets, when it appears like a dark-coloured marble. The soft shell can be cracked between the fingers, and the hardish white nut is seen inside, being about 1 inch in diameter and very meaty. A few of these almost take the place of a meal. Thus far the plant has not been cultivated, the natives only picking the fruit as they find it in the forest. The fruit is four-cornered and contains one nut.

Palissya cordata. Ipa (Yoruba); Unwonwen (Benin); Abo Asha (Ibadan).

It is found in the Benin forest. A medium-sized tree, which might be examined with a view to being a source of dyeing material.

Macaranga Barteri. Arasa (Yoruba).

A small tree or shrub found in Tropical West Africa.

Claoxylon Barteri (Hook.). Itakun, Okare (Yoruba).

It has small flowers. Found near Ipetu.

Anacardiaceæ.

Spondias lutea. Non-indigenous Hog Plum or Yellow Plum. Iyeye, Akika Aka (Yoruba); Ogikan or Ogege (Benin); Nsukakara (Efik).

Although indigenous to India, it has become very widespread in its area of distribution in Africa, where it is found, partly planted or as a “garden escape,” in all the Southern Provinces of Nigeria. It is a medium-sized tree, reaching a girth of about 5 feet and a height of about 50 feet. The very evenly and comparatively deeply fissured bark, in comparison to the size of the tree, is the most typical feature of it. A very open crown, and few straight upward- and outward-tending branches, with very slight side branches and twigs also distinguish this tree from many of the forest trees. The little yellow fruit, about 1 inch long and ¾ inch in diameter, is very much like an elongated Mirabel plum. It is between an eighth and a quarter of an inch of yellow flesh when the nut or stone is reached inside. The leaves are thin and pinnate, with ten to twelve pairs of pinnæ on each leaf. Sometimes the bark is rough and almost prickly. The branches and cortex in smaller trees are more or less covered with little nodules which sometimes develop into small thorns. The fruit is sweet, but rather sharp to the taste, almost tart. It is, however, refreshing in the hot weather whilst on the march.

The timber is whitish-yellow, not very hard, although it is scarcely attacked by white ants, chiefly perhaps owing to the fact that any green piece of wood with some bark on it will grow when lying on the ground. It planes well, splits easily, and takes nails.

It is a rapid-growing, light-loving tree which does not thoroughly protect the soil nor enrich it very much with its foliage. Natural regeneration is poor. It is most readily propagated by means of cuttings, which may even be about 6 inches in diameter and quite as long as posts. With the spread of farms and other buildings it tends to become more widely distributed over the country. It demands a moist soil with a fair amount of depth.

The timber does not show such qualities as to justify its export, but occasionally the larger trees might be sawn up for planks for local use. It is very useful for making live fences, which grow fast and do not cast much shade. In fruit the tree also looks very pretty.

Native Use.—The tree is used for live fences for gardens and farms. The fruit is eaten, but not to an enormous extent, as it is said to form tartar on the teeth. Amongst the Yorubas, parts of the roots and branches are used for axe and hoe handles.

Spondias sp. Ekika Aja (Yoruba).

This tree may be the same as Pseudospondias microcarpa, but it has only been determined from a specimen obtained from the Oshun Reserve. This is somewhat further south and in a moister region than the Pseudospondias microcarpa.

Pseudospondias microcarpa. Okika (Yoruba).

It is a somewhat rare tree in the Abeokuta and Ibadan provinces of Nigeria. Apparently there is a small-fruited tree of this species in the Olokemeji Reserve. The tree itself attains a larger size than S. lutea, reaching a girth of 8 feet and a bole of 20 feet. The growth is less free and the bark is much darker and more fissured than S. lutea. It has not been felled for export; the natives have no particular use either for the wood or the fruit.

Anacardium Occidentale. Non-indigenous Cashew Nut. Kaju (Yoruba).

This tree has become a garden escape on the Ekoi plains near Lagos, where it forms dense thickets. It is not indigenous to West Africa. The tree bears well, and the Brazilians resident in Lagos make a jam out of the fruit. The nuts are roasted and regularly sold in the market, to Europeans chiefly. The branches of the tree are sometimes lopped off and cut into short pieces for firewood. It is usually of very sprawling habit, with a short bole only 3 or 4 feet long. It is not found in the forest proper.

Botanical name unknown. Blacksmith’s Charcoal Wood. Akkun (Yoruba); Azimommon, Onyenu (Benin).

It is found in the Benin and Abeokuta provinces of Nigeria, Obagie Reserve and Oyon River.

It is a large tree, with large leaves and compact crown. It has a very small, berry-like fruit; found growing on moist soil in the evergreen forest, sometimes found in the fringing forest of river banks of a dry zone.

Timber.—The timber is very hard, grey in colour and perhaps flexible. The bark is rough and finely fissured. It is inclined to peel off. The slash is pink. The wood is very fibrous, and in the cross-cut section the pieces between the fibres look like very small pinholes. The wood when freshly cut has a sweet, rather pleasant smell.

European Use.—It has not, so far, been sold for export or local use.

Native Use.—The stems of the small trees are used for axe-handles, and this tree is esteemed by the blacksmith for making charcoal. It is also cut into planks.

Anacardia sp. Rat Poison Mango. Akkum (Yoruba); Pweku Pweku, Azemome (Benin).

The Benin native name means literally “Rat-kill, rat-kill,” but I have never been able to discover exactly how the poison is used. It is rather a rare tree of the Benin forest of the Benin province. It reaches a height of about 80 feet and a girth of 9 feet. It bears a large fruit about the size and shape of a good mango. This is certainly one of the best fruits of the native trees. It has a much sweeter scent than that of the mango, and the taste is also much sweeter. From experiments made it is not poisonous to chickens, goats nor sheep, but none of them, except the chickens, took it at all willingly. The fruit is said to be very poisonous to man, but its delicious flavour tempts the tasting of it. Certainly, in very small quantities it is not poisonous, and it would be interesting to know in what quantities it is so. The slash is yellowish-white. The sapwood is white and the heartwood of a dull brown colour. It is a hard and heavy wood. It saws with difficulty. It is a shade-bearing and soil-protecting tree. The natural reproduction appears to be poor.

The timber has not been used locally, nor has it been sampled for export.

Celastraceæ.

Gymnosporia Senegalensis. Shepolo-hun (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Icacinaceæ.

Pyrenacantha sp. nov. Abara (Yoruba).

It is found in the Epe Colony of Lagos, Nigeria.

Sapindaceæ.

Lecaniodiscus cupanoides. Akika. Aka-Ishin (Yoruba); Utan-tan (Benin).

It is found in the Abeokuta, Ibadan, Ondo, Warri, Ogoja and Calabar provinces of Nigeria. It is a small, shrub-like tree, reaching a girth of about 1 foot and a height of 15 feet. The leaves are very small, the timber extremely hard and cross-grained. The wood is used by the natives for rafters, hoe-handles and sometimes mortar-pestles; the root is said to have medicinal properties.

Blighia sapida. Akee or Akee Apple. Ishin Ishin-oka (Yoruba); Ukpi nufwa (Benin).

It is found in the Southern Provinces of Nigeria. It has an edible aril, which is yellow in colour. It is cooked before being consumed. It is a very ornamental tree, and bears fruit when quite young, which, being orange-coloured, looks very pretty amongst the green foliage.

The fruit is more or less triangular in shape, and when ripe splits open up to the base, releasing three black nuts with a yellow aril. The fruit is orange-coloured with a pink flush. It is a medium-sized tree, reaching a girth of about 6 feet and a height of about 60 feet. The bark is smooth and grey in colour and comparatively thin. The crown is oval in shape and much more open than is the case with Phialodiscus sp. It has a moderately large pinnate leaf with two pairs of pinnæ. The flowers are small and comparatively inconspicuous. It is found chiefly in the mixed deciduous forest zone. It is most frequently seen in the neighbourhood of villages, where it has probably been planted.

The sapwood is white and the heartwood brown, moderately hard, durable and termite-proof. It planes well, though occasionally it is cross-grained. The wood is of fine texture and has a certain amount of sheen. It saws well, but does not split easily. It takes nails only moderately well. It tends to darken a little on exposure to the air.

This tree is moderately fast-growing, at first shade-bearing and subsequently light-demanding. It is also a soil-protecting and soil-improving tree. It appears to like comparatively rich soil, though it may also be seen on poor ground, where it does not thrive. Natural regeneration is not good, chiefly owing to the fact that many animals eat the seeds, besides human beings. It will bear fruit in the fifth year, more especially from stump shoots. It sprouts well from the stump and stands a great deal of pruning.

The timber has not been cut for export, and only occasionally has it been sawn up for local use. It is, however, worthy of further attention as a local building timber. As an ornamental tree it is worthy of a place in a large garden. With its open crown it is a comparatively clean tree, and does not harbour flies and insects.

Native Use.—In places of timber scarcity it is occasionally used for house-poles. The aril of the fruit is eaten after being cooked, but apparently this custom is much more prevalent in the West Indies amongst the descendants of the African slaves. In many parts of Nigeria it is quite unknown as an edible fruit.

Phialodiscus sp.?. Bush Akee. Awewe, Ishin Oko, Isinko (Yoruba); Ukpi nikwi (Benin).

Identified from a specimen in the Forestry Arboretum, Calabar.

Chief Characteristics.—The capsule splits into three and allows three black seeds to escape, with small yellow aril round the base. The whole fruit and the individual seeds are much smaller than Blighia sapida, though, as the Benin name indicates, this is so similar that it is called the black variety of Ukpi. The fruit is triangular in shape, otherwise very much the same size as African Oak, Oldfieldia Africana.

Found in the Calabar, Owerri, Benin, Ondo and Abeokuta provinces of Nigeria.

Blighia sp. Ishin Oko, Oko Ishin (Yoruba); Ukpi nikwi (Benin).

Distribution.—Ibadan, Abeokuta, Jebu Ode, Benin, Owerri and Calabar provinces of Nigeria. Probably same as Phialodiscus sp.

Chief Characteristics.—The very insignificant white flower-spikes, hidden away amongst the leaves, but attracting numerous bees in February and March, characterize this variety. It is a medium-sized tree, with light-green foliage, thin, lanceolate leaves, a thin grey bark, smooth and close and oval-shaped crown, through which one cannot see. The capsule is dehiscent, with three black seeds with yellow arils, smaller than Blighia sapida, but otherwise quite similar in shape, except that the capsule is more triangular than that of B. sapida, and shorter also and of a dark brown colour. It is not unlike the fruit of the real African Oak, Oldfieldia Africana, except that this is quite spherical in shape.

Timber.—White sapwood and light-brown heartwood, which is moderately hard. It does not plane well, and is sometimes cross-grained; the texture of the wood is fine, but is a little fibrous. It saws easily, but does not split well. The bole being very cylindrical in shape, comparatively long, even-widthed planks can be cut out of it.

It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration does not appear to be good. It is somewhat exacting as to soil, and does not thrive in a moist sand. It is somewhat fire-resisting. In the dry season a good deal of dew is condensed on the leaves, but not so much as in other genera, such as Anona.

The timber has not been cut for export, nor has it been sawn up for local use. It deserves, however, further trial as a local building timber. A specimen, from which the tree was determined, stands in the forest region of Calabar.

Use.—Native implements of various kinds.

Deinbollia pinnata. Oju Agbigbo (Yoruba); Ebegogogbo (Benin).

It is a small, shrub-like tree found in the Abeokuta and Benin provinces. The small orange-brown-coloured seeds are of similar shape to, though smaller than, Blighia sapida; they are, however, more elliptical. The stem of the tree, if found with the proper crook in it, is used for making hoe-handles. The leaf is pinnate. This tree only attains a small size, and is found as undergrowth in the mixed deciduous forest zone.

Cupania akeesia. Small Ukpi nufwa. Ishin-jeje, Ishin-gege (Yoruba); Ukpi nufwa (Benin).

This is a small, shrub-like tree, common in the Abeokuta and Benin provinces of Nigeria.

Rhamnaceæ.

Zizyphus mucronata (Willd.). Walking-stick Wood. Ekanesie adie (Yoruba).

This is a shrub-like tree of the dry-zone forest, but does not bear such a nice fruit as that of Z. jujuba.

Tiliaceæ.

Glyphea Grewioides (Hook.). Atori (Yoruba); Uwenyriotan, Uwemriotan (Benin).

It is a small tree, not much more than a large shrub, with small leaves, and very common in the undergrowth of the evergreen forest. It is not a hard wood.

It is found in the Benin, Calabar, Abeokuta, Ondo and Ibadan provinces of Nigeria. It is usually found as one of the smaller trees forming the undergrowth in the evergreen forest. It yields a strong, hard wood near the junction of the roots with the stem, though otherwise it is soft.

It is a shade-bearer, and usually grows in a moist place. Reproduction by seed, judging by the amount of self-grown seedlings found, must be good. It thoroughly protects the soil and enriches it. It thus serves a useful purpose in the undergrowth of evergreen forests.

Native Use.—It is used as a “Ju-ju” whip in Benin and for walking-sticks. Small stump shoots can also be used for yam supports and for making hoe-handles.

Cistanthera sp. False Hill Mahogany. Oro, Apata (?) (Yoruba); Abolo (?) (Benin).

It is found in the Abeokuta and Benin (?) provinces of Nigeria. It is a very common tree on the hill-sides of the Olokemeji Reserve, and to a lesser extent in the Ilaro Reserve. It is a medium-sized tree, reaching a growth of 8 feet and the bole length of about 40 feet. The bark is very curious, with occasional very small, long and narrow fissures and tiny pits scattered more or less a foot apart up and down the stem. It is almost gregarious in habit.

The timber is a red-brown colour with a white sapwood. It is very similar to mahogany and could probably be sold as such. It is moderately durable. A tree which fell down in the Olokemeji Reserve during 1910 was not absolutely unsound in 1915.

It is apparently a slight shade-bearer and rather slow grower. Reproduction by seed is evidently rather doubtful, as few or no self-sown seedlings are found in the neighbouring forest. It has not been cut for local use, nor for export, though sample logs should be tried on the Liverpool market to test its value.

The natives use the roots for medicinal purposes, but they do not use the timber.

Grewia carpinifolia. Itakum Okere (Yoruba).

Olokemeji.

Grewia tetragastris. Ora-Igho (Yoruba).

It is a shrub, reaching a height of about 5 feet, of the mixed deciduous forest in the Abeokuta province of Nigeria (Olokemeji Reserve).

Triumfetta rhomboidea. Boko pupa, Akobolobolo, Ilasa omodo (Yoruba); Nesuwa (Benin).

Triumfetta cordifolia. Esura (Yoruba).

Triumfetta sp. Apiko (Yoruba).

Corchorus acutangulus. Abo-jaga (Yoruba).

Corchorus olitorius. Eyo, Ganbe (Yoruba).

These are common plants in the Ogoja and Abeokuta provinces of Nigeria.

They yield long-stapled fibre worth about £27 a ton. Owing to the fact that they grow wild and are not cultivated by the natives, the difficulty is to be able to collect sufficient quantities in one locality to pay for the cost of retting, baling, etc., to make the fibre production a paying proposition.

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

It is a comparatively well-known fibre-plant, but has not, however, been cultivated, the natives having many other profitable crops to grow.

Bombacaceæ.

Eriodendron Orientale. White Silk-Cotton Tree, Blind Wood or Kapok, Cotton Tree. Araba, Eggun (Yoruba); Okha (Benin); Ukum (Efik); Akbo (Ibo, Asaba); Shakka (Brass).

It is a common tree in all the Southern Provinces of Nigeria, though it is not found in the most northerly part of the drier ones. With the exception of a few scented mahoganies, this is the largest African forest tree. Its huge root buttresses reach up over 20 feet from the ground. Its giant limbs, as thick as an ordinary tree-trunk, stretch out almost 100 feet from, and are supported on, the great column of the bole, often itself over 100 feet high. Large muscular-like protrusions join up the limbs with the trunk and the latter with the root buttresses, giving the tree a peculiar look. The flowers are white, with yellow stamens. The fruit is a soft, oblong, dehiscent capsule, opening when ripe and releasing black seeds about twice the size of B.B. shot. Attached to this seed is a ball of white fluff. This last is known commercially as Kapok. At the time of the bursting of the capsule of this tree the whole air near by appears filled with white flakes, and the ground later is white as if after a fall of snow. It is almost the quickest growing of all the African forest trees. It grows in the evergreen forest as well as in the mixed deciduous forest.

The timber is white and soft and inclined to have little yellow streaks. When dry it is brittle, though very fibrous to cut when fresh by either axe or saw. It soon rots when exposed to the weather. Natural regeneration by seed is good, especially on the banks of rivers. It tends to extend its area of distribution with the clearing of the heavy forest area in making farms. It is a light-demanding tree.

In Germany, before the war, African Kapok found a ready sale at about 9d. per pound. Samples of Kapok were sent to England and were valued at less than those of the East Indian variety.

The timber has been used as a “blind” wood for furniture, and had a regular market at Hamburg before the war. It has been tested in England for pulp-making, but the fibre is stated to be too short, and so it is of no use for this purpose.

Native Use.—The Kapok is used for stuffing pillows, for which 1s. apiece is charged. Large oblong pieces of the root buttresses are used as native doors and as drying slabs for fresh dyed clothes. Whenever timber fails it is used for fishing canoes (the cheapest kind).

Eriodendron anfractuosum. Cotton Tree, similar to Orientale. Araba Eggun (Yoruba); Okha (Benin); Shakka (Brass).

Was determined from Western Province material, but it is doubtful whether it is a different species from that found in other parts of Nigeria.

Bombax reflexum. Red-flowering Cotton Tree. Ponpola, Lauro (Ibadan, Yoruba); Obokha (Benin); Onihokha, Benin (when in flower); Titiro (Egbado).

It is found in the Abeokuta, Ondo, Benin, Owerri and Ogoja provinces of Nigeria, where it is often seen in the mixed forests and in clearings in the evergreen forest zone.

Chief Characteristics.—It has a larger leaf and thorns than the other Buonopozense (?) (Onikokha of Benin). The most typical feature is the very thick, tulip-like red flower of this tree. This falls to the ground, and is seen on roadways and pathways, indicating the presence of this tree. In February or March, when the flowers appear, the tree is bare, so that the bright-red flowers make it all the more striking. The tree is smaller than the Eriodendron Orientale, attaining a girth of about 12 feet and a bole length of 50 feet. The root spurns are much slighter, in most cases scarcely amounting to small buttresses. The cortex is more soft and spongy than E. Orientale.

The timber is white, very soft, not quite so tough nor fibrous as E. Orientale, but rather more porous. It planes more easily, dries rather better, splits with less difficulty than E. Orientale, and saws with less trouble.

It is a very fast-growing, light-loving tree, which does not protect or enrich the soil very much with its leaf fall. Natural regeneration appears to be fair, though, considering the enormous number of flowers almost each year, it is surprising that the tree does not spread more rapidly in new clearings in the forest.

The timber has not been tried for export nor for local use.

The bark, roots and leaves are used amongst the Yorubas for medicinal purposes. The bush deer eat the flowers, when they fall: the Benin native says if he does not call the tree Onihokha, the deer will not come and eat it.

Bombax sp.?, Bombax buonopozense?. Ponponla (Ibadan, Yoruba); Obokha, Onihokha (Benin).

It is found in the Abeokuta, Ibadan, Ogoja and Benin provinces of Nigeria, in the mixed forests, where it is not very common.

Chief Characteristics.—Compared to Bombax reflexum it has a smaller leaf, smaller thorns, but not so many on the stem. It has a similar red flower, opening, however, much more widely. It reaches about the same size as the Bombax.

The timber appears to be very similar in most ways to B. reflexum. It has not been felled for export, nor has it been used for planks for local use. Occasionally the leaves are used for medicinal purposes.

There appears to be some doubt as to whether this is really a separate species from that of B. reflexum. It is, however, sufficiently different to be considered quite a distinct variety, though perhaps not actually a different species.

Adansonia digitata. Monkey Bread, Baobab. Ose (Yoruba); Usi (Benin).

It is a moderately common tree in the Onitsha and Abeokuta provinces of Nigeria. Isolated specimens are also found elsewhere. The most typical feature of this tree is the huge thick trunk, tapering up into the branches, out of all proportion to the length of these and the twigs. These are much thicker than the branches and twigs of other trees. The green, elongated spherical-shaped fruits hang by a stalk, giving the tree the appearance of one decorated for a Christmas festival. The leaves are truly digitate and not unlike those of the cotton-tree, though they are thicker and darker in colour. The bark is very thick, spongy and fibrous, and of a light-grey colour. The bark, seeds and roots are used medicinally. The fruit is eaten in time of scarcity.

The fibre is used in England for paper-making.

Sterculiaceæ.

Sterculia Rhinopetala. False Chestnut. Ekko Okpon, Orodu or Orodo (Yoruba); Enwiwan (Benin); Otutu (Jebu); Awraw (Egbado).

It has a smooth, light-green bark, which remains soft, but is whitish with age. The wood is white and soft, and apparently there is no difference in the heartwood. It has a small seed with a wing on each side of it. For external work it is not durable, but when seasoned for internal fittings, such as doors or ceilings, it is more useful.

It is common in the Oyo, Benin, Calabar and Abeokuta provinces. It is found in the mixed deciduous forests, especially in the Mamu and Ilaro Forest Reserves. Also, wherever it is found there is a comparatively large number, though it is not gregarious in habit.

It was stated to be of no commercial value in the Liverpool market in 1906, but in a subsequent report it was said to be worth 1s. to 1s. 6d. a cubic foot, as walnut, though there must have been some mistake in the name.

Native Use.—The mushrooms which grow on its stem after it is cut down are used for soup. These are known as Epweperu.

Sterculia tomentosa. Okagbo (Yoruba); Ukpiwenwan (Benin).

This tree is found in the Abeokuta and Benin provinces. It reaches a height of from 40 to 50 feet. The fruit is ripe in December and January; it is kidney-shaped and covered with a dense collection of very fine reddish hairs. It grows in clusters.

Sterculia sp. Iwu (Yoruba).

It is found in the Abeokuta province of Nigeria and is a medium-sized tree which yields a white wood which is none too hard nor soft.

Sterculia tragacantha. African Tragacanth. Owun, Omunu, Omar, Ogidu (?) (Yoruba); Oporipor, Iporipor, Okoko (Benin).

Chief Characteristics.—It shows a brown slash when cut. The bark is very fibrous and the white sapwood is full of large open pits, which gives the wood the appearance of being entirely fibrous. It yields a pink-coloured gum, which hardens after a few days. It bears large oval-shaped leaves, which tend to be bunched at the end of the twigs. The pods are less than half the size of Sterculia cordifolia and are covered with light-brown velvety hairs on the outside. These pods open, making each appear coracle-shaped, with eight to ten small brown seeds attached to the bottom rib of the pod. The foliage looks almost grey-white from underneath. The bole of the younger trees is greyish-white and usually for 30 to 40 feet free of branches. It reaches a girth of about 8 feet. The wood is white and softish, planes easily and works up to a neat finish. Silviculturally, the tree stands between the light-lovers on one hand and the shade-bearers on the other, although it is usually seen growing comparatively free from other than natural shade. It does, in fact, stand a considerable amount of shade in the younger stages of growth as well as later, when it may be overgrown by larger growing trees. It is usually found in groups at the edge of the forest.

It sprouts again from the stump, but almost each year large crops of seeds are borne on the tree, and this would seem to be the chief method of reproduction.

The tree has not been cut for local use, nor has it been exported. The Yorubas and Benis use the smaller trees as poles for house-building, but it is not considered a good wood.

Sterculia cordifolia. Heart-shaped-leaved Sterculia. Okporoporo, (Akure); Ogugu, Ogungun or Ogrugru, Oburuburu (Yoruba); Idogoho, Okoko, Okokwo (Benin); Dikir (Efik); Ibitoto (Bembi).

Distribution.—It is found in the Jebu Ode, Abeokuta, Ibadan, Benin, Onitsha, Owerri, and Calabar provinces of Nigeria. It is one of the most common trees in the mixed deciduous forests.

Chief Characteristics.—The large heart-shaped leaves and the curious twist to the lower part of the stem, which makes the root protuberances quite angular. It is never quite straight and forms a heavy oval crown.

The very large, oval, soft, almost fleshy, dehiscent pod, with its large winged seeds, is most typical of this tree. The crown is supported by three or four large limbs with comparatively few side branches. The foliage is very dense, though even in a tall tree the individual heart-shaped leaves show up quite distinctly. It is almost gregarious in habit, usually groups of four or five being found in one place. It is nearly always found on the banks of small streams which may dry up in the dry season. It is a shade-bearer, though moderately quick in growth. The wood is cross-grained, and emits rather an unpleasant smell when cut. The sapwood and the heartwood are both white, with a reddish tinge through it. It is soft, but becomes much harder when dry. It sprouts from the stump when cut down. Reproduction by seed is moderate. It has not been used locally, nor has it been exported. The natives in the Benin and Yoruba countries use the butt of medium-sized trees, especially those with a fork, for house-building. It is not attacked by white ants.

Sterculia nr. oblonga. Opepe (?) (Yoruba); Orodo (Benin).

It is a common tree of the Benin province of Nigeria, found in the evergreen forest.

It is a question whether this species is the one with a very hard, leathery, half-dehiscent pod, showing about ten orange-coloured oblong seeds inside it. These seeds have sometimes been termed Okoko by the Benis, but they are, no doubt, not obtained from the fruit of Sterculia cordifolia. These seeds also are not winged, and are comparatively fleshy and soft compared to the dry, rather hard, large winged seeds of Sterculia cordifolia.

Sterculia cinerea. Tartar Tree. Lakole (Yoruba); Ururata (Benin).

It is rather an uncommon tree of the Benin province of Nigeria. It is found at the edge of the mixed deciduous forest with the dry-zone area of vegetation.

Firmania Barteri. Rope Tree. Eso or Esho (Yoruba); Akoko, Nihau (?) (Benin).

It is a large tree with duck-egg-green bark and an uneven buttressed base, with a bole length of 30 or 40 feet and a girth up to 12 feet.

Distribution.—It is one of the most prevalent trees in the Olokemeji Reserve in the Abeokuta province of Nigeria, and found all through the mixed forests of the Western Circle and also in the Obubra division of the Calabar province, but it has so far not been found in the Benin province.

Use.—A fibre, worth £14 to £20 a ton, is made from the bark of young trees attaining 3 inches in diameter.

A most conspicuous tree in October and November, as it is covered with small red flowers and is leafless at the time. It has a papery fruit with a small round seed attached to the base. These fruits are also most conspicuous in February and March, making the tree look as it were covered with red flowers for a second time. The large, poplar-shaped leaves with comparatively long stalks often tremble in the slightest breeze in a similar way to the aspen. The wood is soft, white and fibrous, with no distinguishing colour between sapwood and heartwood. It splits comparatively easily, though, once it is dry, with difficulty. It is easy to plane, though difficult to obtain a smooth surface owing to the grain often being twisted. The light seeds almost float in the air, the result being that they are spread everywhere, and thus come up chiefly in the open spaces and at the edges of rides and roads, almost to the detriment of any other species. It is one of the fastest growing of all the African trees, and being a light-lover as well, rapidly covers all the available ground. In fact, in the mixed deciduous forests it tends to gain in its area of distribution year by year. In an enumeration in the Olokemeji Reserve, instead of finding a few thousand trees, as in the case of most species, hundreds of thousands of this one were found.

The branches of the young tree grow more or less in whorls at right angles to the trunk, and, combined with the comparatively large leaves, thoroughly cover the ground near by. Stump sprouts grow after a tree has been felled, though natural reproduction by seed is by far the most prevalent method. It has not been felled for local use nor has it been exported. The Hausas living in Nigeria cut down the small trees (saplings 1 to 2 inches in diameter), peel off the bark, dry it, and spin it into rope, which is used for tying loads of Cola or other produce. When freshly made it is soft and pliable, but when it is dry the fibre becomes very harsh and rather difficult to tie.

The wood is used for floats for fishing on the Niger.

Heritiera sp?. Oviegikwe (Benin).

It is found in the Benin and Ondo (?) provinces of Nigeria.

The tree is large, reaching a girth of about 12 feet. The seed is papery and full of air, so that when trodden upon it collapses. The leaf is of medium size, more or less pinnate. The timber is white and soft; termites attack it. It has not been exported or used for local buildings.

Native Use.—The leaf is used medicinally, and the timber is used for making drums (the frame) by hollowing out the trunk of a tree. It is also used as walls for a temporary house (when dried or not); for this purpose it is split in pieces.

Heritiera sp.?. Igoso (Benin).

It is an uncommon tree of the Benin province of Nigeria. It is found in the evergreen and mixed deciduous forests. The fruit is considerably smaller than Oviegikwe.

The natives apparently have no use for this tree. However, timber obtained from trees of this genus has proved so useful and durable that a trial of the wood of this species seems advisable.

Triplochiton Johnsonii (Ch. Wright). African Maple, Bush Maple. Arere (Yoruba); Obechi (Benin).

This is one of the common trees of the Abeokuta, Ondo and Benin provinces of Nigeria; it is found in the mixed deciduous forest zone, more especially in the moister regions of these forests. Like T. Nigericum, it is one of the largest of all the forest trees, reaching a height of over 120 feet and a girth of 25 feet. The leaf has five lobes, and is thus distinguishable from T. Nigericum, which has seven. The bole is long and clean and most cylindrical in shape; the buttresses, as a rule, do not reach such a great height as in the case of T. Nigericum. On the whole the bark is smoother and, especially in the younger specimens, almost shiny. The flowers and fruit are very similar to T. Nigericum.

The timber is white, both heartwood and sapwood, and shows a considerable amount of elasticity; rather liable to warp when seasoned. It works up well and takes a satiny sheen. The grain is comparatively fine—in fact, a little finer than that of T. Nigericum; the pores are long and very narrow; it works up well with a plane, takes nails easily, does not split well; it saws with great ease; it is not termite-proof. If freshly cut and placed under cover, it suffers most severely from the attacks of a very small weevil which reduces the wood to a fine powder; it is noticeable that when the timber is entirely dry the surface hardens very considerably and it is less liable and almost immune from attack. When thoroughly dry the wood weighs 35 pounds per cubic foot.

It is a very rapid-growing, at first slightly shade-bearing and of recent years an eminently light-loving tree. It has soil-protecting and soil-improving qualities. Natural regeneration appears to be very good. Self-sown seedlings show a height-growth of over 6 feet per year. It likes a moist soil, which need not be very rich, but it must have considerable depth. It is rather liable to be blown by the wind or sometimes broken, if in an exposed locality.

Locally it has been used for boxes and other articles, which have proved quite durable; it has been used as inside planking and other interior work, and so long as it is carefully seasoned it does not warp very badly; it is probable that it is one of those timbers that would yield better results by kiln drying. In the Central Circle it has been sawn up as planks for a considerable time, but they have been attacked to a great extent by a small weevil. The local people use the bark for making roofs and the wood for doors for their houses.

In 1906 sample logs of this timber were sold in the Liverpool market as Satinwood, but were not considered equal to Anyeran (Afrormosia elata). Since that date no more trial shipments have been made, so it remains to be seen whether under the altered conditions and the pressing demands for timber in Europe a market cannot now be found for the vast quantities of this timber from Nigeria and other West African countries.

Triplochiton Nigericum. Soft Satinwood. Arere (Yoruba); Kpa (Efik).

It is found in the Abeokuta, Ondo, Owerri and Calabar provinces of Nigeria; it is a common tree of the mixed deciduous forests. One of the distinguishing features of this tree are the maple-like leaves. This species has seven lobes to the leaf; the leaf itself is softer and almost velvety compared to the true maple leaf. The lobes themselves are not quite so sharply pointed and the leaf stalk is considerably thicker. The fruit also is very much like that of the maple, but is a quadruple samara instead of being only a double one. The tree is one of the largest of the whole forest, reaching a height under favourable conditions of nearly 150 feet; the bole alone may reach a height of 90 feet with a girth of over 20 feet. The trunk is very cylindrical in shape, showing a well formed figure, but not so good as either that of Agba or Gum Copal. It is only broken up by the root buttresses, which often reach 10 to 12 feet from the ground before they merge into the stem; the bark is grey, sometimes almost white and almost smooth; in old age, shallow fissures sometimes form. The slash is greenish-white, and a little watery sap moistens the cut after a short interval. The crown is ovally spherical and occupies over one-third of the height of the tree. The flowers are mottled pink and white.

The sapwood is white and the heartwood is the same colour, with no great distinction between them except the greater dryness of the heartwood. The timber is soft and not durable, and is not termite-proof; it does not split very well, saws easily, and planes fairly well and takes nails comparatively well; does not plane up to a very smooth surface.

It is a very rapid-growing, at first shade-bearing, and during the last few years a light-loving tree; it has soil-protecting and soil-improving qualities. It is deciduous for a short time each year; flowers in February or March, and the seeds are borne towards the end of the rainy season. Natural regeneration is very good; it sprouts very strongly from the stump. It is really somewhat exacting as to soil, liking a moist soil of good depth and with plenty of drainage; it will not stand in waterlogged ground, though an occasional flood does not hurt it. Plantations have been made with this tree, and the growth thus far has been very rapid; self-sown seedlings, however, show greater development in the same period of time.

Locally, the root flanges are used for making doors and occasionally the tree has been cut for planks; it is said that the timber is not supposed to be quite so durable as that of T. Johnsonii, but in reality there is very little difference between them.

Triplochiton n. sp. Bush Maple. Obechi (Benin).

This tree was found in 1906 in the forest near the Anwai, not far from Onitsha Olona, in the Asaba district of the Benin province, and is very similar in habit and growth to the other two species.

Buettneria. Obechi (Benin).

Benin.

Pterygota. Poroporo (Yoruba).

It is found in the Abeokuta province of Nigeria. It is not very prevalent in the mixed forests of the Olokemeji Reserve, and is a large tree, 8 to 10 feet in girth. The wood is said by the natives to be durable.

Cola cauliflora (F.). Cola Mahogany. Isienwe (Benin).

It is common in the Benin province of Nigeria, in the mixed deciduous forest zone, where it is not very prevalent. It is a medium-sized tree, reaching a girth of 6 feet.

The seed is a small nut. The leaves are very dark and are comparatively large. The bole reaches a length of about 20 feet.

The sapwood is whitish and the heartwood of a red-brown, similar to mahogany. The texture is, however, not quite so fine and a little more fibrous. It planes fairly well and takes nails fairly easily, but it does not split well. It is durable and is said to be termite-proof. It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration is only moderate, and it sprouts slightly from the stump. It is somewhat exacting as to soil, and is usually found in a loamy sand, with plenty of moisture and depth.

It was valued at 2d. to 2½d. a superficial foot as mahogany of fair character in the Liverpool market in 1906. But since then no more has been felled or exported.

The natives use it as firewood in the Benin country. It has not been felled for local use.

Cola laurifolia. Laurel-leaved Cola. Foma (Yoruba).

It is an uncommon tree, found in the Olokemeji Reserve of the Abeokuta province of Nigeria. A small tree with small flowers.

Cola acuminata (Beauv.). Common Cola. Obi Abata (Yoruba); Eve (Benin).

It is a common tree of the Calabar, Ogoge, Owerri, Warri, Benin, Ondo, Ibadan and Abeokuta provinces of Nigeria.

It is the ordinary Cola of the Benin villages, but it is also found in the forest. In other parts of the country it has been planted along the sides of the roads leading into Egbado, Jebu, Ode, Ondo, Ikale and Ilesha villages.

Always standing in the shade and with a heavy evergreen foliage, the cream-coloured flowers with a pink streak on each petal show up very clearly when the tree comes into bloom in February or March. According to the native ideas, the tree must never be pruned, nor, in fact, should it be cut either partially or wholly under any circumstances. However, in passing to and from their farms, boys and young men often chip the trunk of the tree with a matchet. This, they say, has the effect of making it produce more fruit; otherwise the tree always looks very dirty, and often the trunk and the branches are covered with epiphytic ferns or orchids. Occasionally, once a year or once in two or three years, the branches of the trees standing nearest to a Cola are cut away and the ground immediately surrounding a Cola tree is cleared of undergrowth. The crop of fruit borne varies very much from year to year. One year a native may make a pound or so from his Cola tree, whereas in another he perhaps makes very little.

To face p. 354.

The sapwood is white and the heartwood a dull whitish-yellow. It is moderately hard, very close grained and of fine texture, with a dull lustre; is moderately durable, but is liable to be attacked by a very small furniture borer. It is termite-proof. It planes well, does not split easily, takes nails and saws well. It is apparently an excellent wood for carving. It does not shrink nor warp very much. It is more durable for interior work than for outside, where it is liable to get soft and to crumble away. It is sometimes brittle; it does not burn well.

Native Use.—The fruit is eaten and is used as an article of export both to the Northern Provinces and also to the Continent. The wood is used for making “Ju-jus” (Esu—the Devil) (Images of the King); otherwise it is not cut in the Benin country.

Cola Afzelii. Monkey Cola Tree. Obidu, Obiedun, Ebidun (Yoruba); Awohebitan (Benin).

The brilliant red fruits, about twelve joined together in a spherical bunch, are usually quite a feature of the small tree. The leaves are digitate, but joined at the base, so in reality only a single leaf. It is a much-branched tree with yellowish-grey bark. The crown is much divided, and sometimes the branches almost appear as if in large whorls.

It is found in the Oyo, Abeokuta, Ondo, Benin, Owerri, Calabar and Ogoja provinces of Nigeria.

The wood is white and softish and not durable. It is most common at the edge of the evergreen forest. It attains a girth of about 6 feet and a bole length of about 15 feet. It is a light-lover, though it stands a considerable amount of shade in its youth.

Native Use.—The wood is used for the stock of a cross-bow in the Benin country, and the seeds are eaten at any time.

Cola sp. Obiedum (Yoruba); Ewoha (Benin).

This is a comparatively common tree of the Benin, Abeokuta and Ondo provinces of Nigeria. It is the original Cola of the forest; a medium-sized tree with the typical Cola foliage, found growing singly. It does not appear to bear very heavily, and apparently in some places the local people utilize the fruit, while in others they say it is of no value. It appears to be a whiter and softer Cola than that of the other species, and it does not seem to have such a strong flavour.

The timber is hard and white; it is a shade-bearing and soil-protecting tree. Natural regeneration appears to be poor.

The wood is occasionally used by the local fetish-maker for certain types of fetish in the Benin country. It is considered the most suitable and, in fact, the only wood for this purpose. Although the ordinary Cola which is planted may not be cut, this species is not immune, but it is certainly considered most proper if only the image-maker cuts it.

Dombeya Buettneri. Ewe ofo (Yoruba).

It is found in the Abeokuta province of Nigeria, especially in the Olokemeji Forest Reserve. It is a small, shrub-like tree, varying from 7 to 15 feet in height. The bark is fibrous. In 1908 samples of the fibre were submitted to the Imperial Institute for valuation. Owing to its being rather harsh, woody and weak, it was stated to be worth from £7 to £8 a ton.

Ochnaceæ.

Ochna multiflora. Canoe Tree. Uruk (Efik); Tei tei (Ijor); Tei tei (Brass); Elili (Ibo Owerri).

It is found in the Owerri, Warri and Ondo (?) provinces of Nigeria. It is one of the prevalent trees in the evergreen and brackish swamp forest zone. The tree reaches a girth of 15 feet and a bole length of about 60 feet. It has a large digitate leaf, making the foliage of the tree very heavy and dense. The bark is thick and fissured longitudinally. The crown is long and egg-shaped. The fruit is large, roughly spherical in shape, but ribbed in five places on the surface. It is a shade-bearer, and reproduction is chiefly by seed. The wood is reddish-brown and moderately hard. This is one of the most favourite trees for canoe-making amongst the Brass people. Having a straight grain, the log opens out well into a canoe once it has been hollowed out in the centre.

Ochna sp. Sama (?), Duma name.

It is found near Obudu, in the Ogoja province of Nigeria. It is a small tree of the open deciduous forest, growing at an altitude of about 1,500 feet. The flowers are umbellate and of a pretty red colour. It is a light-lover and grows at the edge of the forest.

The natives apparently have no use for either the wood or other parts of the tree.

Lophira procera. Red Ironwood, African Oak, Red Oak. Ela, Ekki (Yoruba); Eba, Ebba (Benin); Eleba (Jekri); Kuru (Brass); Okikopom (Ibibio); Enwan, Umpenek (Efik); Okut Okot (Oban, Ekoi); Kuru (Ibo Owerri); Okut (Kwa).

Chief Characteristics.—It is a very large tree, up to 6 feet in diameter, with orange-coloured bark, when in the shade of the evergreen forest where it is found, but this soon becomes quite grey when exposed to the sun. The flowers are white, with five petals, and are very fragrant, smelling like musk, covering the ground and scenting the forest in November and December. In October and November the tree is very conspicuous with its brilliant new red foliage, which almost appears like flowers in the distance. On the banks of the Calabar River, above the town of the same name, this is seen to advantage. The fruit is winged, but with one wing twice as long as the other and also broader; the seed is sharply pointed and almost conical in section, and not so meaty as that of L. alata. The crown is spherical, but open; the branches are very twisted and reminiscent of oak. The trunk reaches a length of 90 feet and is almost perfectly cylindrical in shape, with only the slightest indication of spurns at the base.

Distribution.—It is found in the Abeokuta, Jebu, Ode, Benin, Owerri, Ogoja (?) and Calabar provinces of Nigeria. It is one of the commonest trees in the very moist parts of the evergreen forest zone.

Timber.—The sapwood is whitish red, but the heartwood is of a dull red colour with large, long, open pores, partially filled with siliceous salts. This often gives the wood an almost speckled appearance. In a tree of 12 feet girth, the sapwood is usually only 3 or 4 inches thick, making it a very full-wooded tree and thus reducing the amount of wood wasted in squaring the logs. It planes well, with a smooth, shiny surface. Strong shoots often come up from the stump, though owing to the natural seed distribution being good, this latter is the chief means of reproduction. It is a light-lover, with a natural tendency to grow straight up. It is a slow-growing tree, and the leaves, nearly a foot long and almost tongue-shaped, are very large for such a hard-wooded tree. Even when planted 16 feet apart it grows up straight, with only three or four perpendicular branches or even only a fork in the stem. It resists white ants, and the teredo worm does not bore into logs when lying in the water. It is almost gregarious in habit, usually groups being found in one locality, or, as in the moister regions, it is next to mahogany the commonest tree found in the forest. It will withstand floods—in fact, there is an island several square miles in extent in the Oshun River covered with only this species of tree. It is also found again on the upper edge of the mangrove forest where the first solid land begins.

The seeds have not been tested as to the proportion of oil contained in them, but no doubt they contain a similar quantity, in proportion to the size, as those of L. alata.

In 1906 samples of this timber in the round were sent to the Liverpool market, where it was valued as red oak at 2s. to 3s. per cubic foot. It was also stated to be worth shipping in good lengths. Owing to its weight and the hardness of the wood, and thus the extra cost of squaring logs, little or none has been shipped to Liverpool since this report was made. Locally it has been used for piles for wharves and bridges, decking for bridges, wall-plates for bungalows, and occasionally as verandah-posts. It can be floated with Musanga logs or those of Hannoa undulata. Canoes made of this wood are of the most durable kind, so that perhaps it might be tried for boat-building.

The people of Benin use the wood for making pestles for their Fufu mortars, and occasionally it is used as wall-plates. Amongst the Brass people it is sometimes used for making canoes, and amongst many tribes for making food-mortars. Near Lagos it is used for house-building.

Lophira alata. Niam Fat, Small Red Ironwood, Meni Oil, African Oak. Ipawhaw, Ponhon, Ipahan (Yoruba); Awigbi, Ugbeberi, Ishan (Benin).

Small or dry-zone Red Ironwood.

It is found in the Ogoja, Owerri, Onitsha, Benin, Ibadan and Abeokuta provinces of Nigeria.

It is a very common tree in the open deciduous forest of the dry-zone form of vegetation. Often found in groups, but it anyhow is the most prevalent tree wherever found. It does not usually grow straight, but the stem is gnarled and crooked, reaching a girth of about 5 feet. The tree itself only grows to a height of about 30 feet. In appearance it looks like a small oak, but the Shea Butter Tree, Butyrospermum Parkii, is still more like it. However, with its reddish-green tongue-like leaves with wavy edges, it is in reality quite different. The branches spring out of the stem in a more upward direction than B. Parkii, and are more irregular in growth. The bark is orange-coloured and almost scaly on the younger trees, though it goes a grey or black colour when exposed to the light or the annual grass-fires. The flowers are white, sweet-smelling and much more conspicuous than on L. procera. The seed is placed between two wings, one nearly three times the width of the other. The smaller wing is more pointed than the larger; the seed, while being pointed, is stoutly cone-shaped and rather more than a quarter of an inch in diameter at the base, and of a light brown colour.

Timber.—The sapwood is narrow and white in colour and the heartwood is a dull red. It is very hard and tough, but not so heavy as L. procera. It planes only with a rough surface.

Silvicultural Characteristics.—This is one of the few trees which successfully resist the annual grass-fires. Its otherwise prolific seed-bearing capacity is, however, often very much diminished, if not completely spoilt, by the flowers being burnt in January and February, the usual time of the grass-fires. It is a light-lover, but for the reasons already given is a very slow-growing tree. On the whole, although the seeds germinate well, stool and root shoots are probably the chief means of reproduction. The soil under these trees is only partially protected during the growing, and quite exposed to sun and wind during the dry season.

Commercial Value.—Samples of these seeds were sent in 1909 to the Imperial Institute for valuation, when they were found to be worth about £10 a ton; 43 per cent. of oil can be obtained from the kernels, and this is said to be suitable for soap-making and to be worth £25 per ton. Commercial quantities, however, have not yet been exported.

Meni oil was formerly obtained from the seed.

Native Use.—Amongst the Yorubas the tree is used for house-posts, especially when the stem is forked about 10 feet above the ground. The leaves, bark and roots are all sold in the native markets for medicinal purposes. An infusion of the bark of the roots is supposed to be a cure for jaundice (yellow fever, according to the natives). Strangely enough, the seeds are not used as a source of oil.

Gomphia insculpta.

Found at Olokemeji.

Gomphia glaberrima.

It is a shrub found at Olokemeji.

Gomphia nr. affinis.

Found at Ilugbro.

Guttiferæ.

Garcinia conrauana. False Cola, Bitter Cola. Orugbo (Yoruba); Edun (Benin); Odji (?) (Brass); Efiori Efrie (Efik); Efrie (Kwa).

It is found in the Calabar, Benin, Ogoja and Abeokuta provinces of Nigeria.

It is a medium-sized tree with close, spherical-shaped crown. The branches and leaves are comparatively small. The bole is short and the branches very persistent. The most typical feature of the tree is the large apricot-like fruit, of an orange-yellow colour. The bark is smooth and brown in colour. It is found in the evergreen forest. The nut is oblong, of a very dark brown colour with small white streaks all over it. It grows in moist soil.

The timber is very hard and close-grained, with yellow-sapwood and light-brown heartwood. It is said to be durable and planes with a smooth surface. It is often found at a considerable elevation—up to 3,000 feet towards the northern part of Calabar province.

It is a shade-bearer, though it is often found growing alone, having been left isolated when the original forest was cleared to make a farm. The tree grows very slowly but bears comparatively early, and trees are often seen quite laden with the yellow fruit.

The timber has not been exported, but has been cut for local use. It was used by the Public Works Department, Calabar, and proved useful for wall-plates. The nuts have occasionally been exported, but they are comparatively valueless compared to the real Cola.

Native Use.—The nuts are sold in the Yoruba and Calabar markets and 100 to 200 for 3d. in the Benin market. The fruit is also eaten. The roots are used for chewing-sticks (the best in Benin), and taste like quinine. The nuts are ground and used medicinally for headache.

Garcinia Kola.

A little known species, found in the Eastern Provinces, Uwet. It was subsequently determined as Garcinia conrauana.

Garcinia Mannii.

This tree is found in the Western Provinces.

Uses.—Chew-stick is made from the root.

Garcinia, var. nov. brevipedicellata.

This tree grows in the Eastern Circle.

Pentadesma sp.?. Hardwood, Duika’s Chop Fruit. Ogbia (Yoruba); Ekuso or Ikujo, Efiari (Benin).

This tree is found in the mixed forests of the Benin province of Nigeria. One of its chief characteristics is that it has little or no bark, but the cortex is comparatively thin, and remains of a duck-egg-green colour even in trees of comparatively large size. It reaches a girth of about 6 feet and a bole length of about 20 feet. However, it is usually very much forked comparatively low down, and often the stem is by no means straight. The root spurns are not very large, but spoil the shape of the bole at the base.

It is a slow-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration is poor, chiefly perhaps because the Duika eat the fruit; in fact, the Benin name means the chop or food of Uso or Duika.

In 1906 samples of this timber were sold in the Liverpool market as a hardwood, which was considered hard and heavy. Since then none has been shipped, nor has it been felled for local use. Perhaps with the changed conditions in the demand for timber, both hard and soft, a further trial would now show whether it was of any value as an export timber.

Pentadesma grandifolia.

Distribution.—It is found in the Oban Reserve of the Calabar province of Nigeria.

Characteristics.—It is a medium-sized tree, with large oblong leaves having numerous glands and lateral nerves which are about a tenth of an inch apart. The leaves are larger and the exterior sepal shorter than in P. butyraceæ.

Silvicultural Qualities.—It grows in the evergreen forest, is a shade-bearer, and comparatively slow-growing tree.

Utility.—Although the fruit has not yet been collected, it is probable that the nuts would contain a similar oil to those of P. butyraceæ.

Pentadesma butyraceæ. Butter or Tallow Tree. Okarora, Ossa (Ondo); Ekuso (Yoruba) (Ikale); Ijeni Udegbu, Agba (west side), Udegbi (Benin); Orugbo erin (Ondo); Amu Ne (New Calabar); Ikakama Udia Ebian (Efik); Ikakama Udia Ebian, Igbofia (Ibibio); Ntini Nyok (Kwa).

Distribution.—It is found in the evergreen forests of the Jebu, Ode, Benin, Warri, Owerri and Calabar provinces of Nigeria. It is quite prevalent in its typical locality and very damp, almost swampy, regions of the forest near small waterways, even comparatively near the sea.

Chief Characteristics.—It is a thin, tall tree, with dark bark and flatly compressed crown consisting of four or five tiers of branches, very close together in almost true whorls. The foliage is very thick and the leaves thick and leathery. It exudes a mass of gamboge-like latex as soon as slashed, and the slash is orange-red. The latex solidifies on exposure to the air. The large pear-shaped fruit has a soft rind, which usually is pierced by the fall to the ground, and the Cola-shaped seeds are embedded in a soft, yellowish-white pulp. The large sepals at the base of the flower are quite typical, in their persistency often being found at the base of unripe fruit.

Timber.—It has yellowish-white sapwood and light-red heartwood of firm texture, with a certain amount of waviness in it, especially if the tree has been barked in its earlier years. It is not hard, and is easy to work; it does not appear to warp or shrink.

Silvicultural Qualities.—It is a shade-bearer with very persistent evergreen leaves. It will stand in waterlogged land and grow almost to perfection. The branches are also very persistent, and it is only when growing in close proximity to other heavy foliaged trees that the bole clears itself of branches for two-thirds of its length. The stump shoots sprout up when the tree is cut down. The more prevalent form of reproduction is by seed. The mature tree bears quite prolifically almost every year. The timber has not been felled for export, but the seeds are worth £8 a ton on account of the oil that they contain, which is considered suitable for soap-making.

Pentadesma Nigritana. Odgebu (west side) (Benin).

Distribution.—It is found in the Oban Reserve of the Calabar province of Nigeria.

Characteristics.—It is a medium-sized tree with black bark on the branches. The leaves are glabrous coriaceous, 3½ to 4½ inches long and 1 to 1½ inches broad.

Silvicultural Qualities.—It grows in the evergreen forests, is a shade-bearer and comparatively slow-growing tree.

Utility.—The fruit has not yet been collected, but, judging by the locality in which this tree is found, the seeds would contain similar quantities of oil to those of P. butyraceæ.

Haronga Madagascariensis (Kew). Benin Roof-pole. Itue (Benin).

It is a non-indigenous tree (exotic) which is now found in the Abeokuta, Ibadan, Ondo, Benin, Warri, Owerri, Ogoja and Calabar provinces of Nigeria.

It is commonly seen growing up in old farms in the heavier soils of the evergreen and mixed deciduous forest zones. The slash, which is brick-red and exudes a yellowish-red latex, is most typical of this tree. The tree is almost gregarious, forming groups nearly half an acre in extent; the bark peels very easily, leaving a clean white stem which hardens very much on exposure to the air. It is a small tree, attaining a girth of about 2 feet and a height of about 40 feet. The wood is quite white, with a small pink pith about a quarter of an inch in diameter; it is a very light wood and most durable when under cover.

The leaves are of a medium size and rough to the touch. When 2 to 4 inches in diameter the natives cut the trees, clean and strip off the bark, and use them for rafters in house-building, especially in the Benin and Yoruba countries.

Symphonia globulifera (Kew). Hog Gum.

It was reported from the Calabar province.

Allanblackia floribunda. Orogbo erin (Yoruba); Izeni or Iyockan (Benin); Atta (Efik); Egba (Ibo, Owerri).

Distribution.—It is found in the evergreen forests of the Jebu Ode, Benin, Owerri (?) and Calabar (?) provinces of Nigeria. This tree usually grows on less moist soil and further away from water than P. butyraceæ, though it likes a moist and deep soil.

Chief Characteristics.—The long, hard, brown, enlarged sausage-shaped fruit hanging on a stalk shows, when cut, large seeds scattered in white pulp, and is thus different in this respect to Pentadesma, which has dark-brown seeds embedded in a soft, yellowish pulp. The slash is yellow, but only exudes a little yellow latex at first. The branches are not so verticillate in form as Pentadesma, but are more pendulous, especially when the tree is in fruit. They also are further apart and give the crown a more open appearance. The fruit is three times the length and the diameter rather more than that of P. butyraceæ.

Timber.—The sapwood is whitish-yellow and the heartwood yellowish-red and moderately hard. It is not attacked by white ants; it does not split easily, but planes with a smooth surface. It is a medium-sized tree, reaching a height of about 80 feet, with a bole length of 20 feet and a girth of 8 feet.

Silvicultural Qualities.—It is a shade-bearer and grows comparatively slowly. Natural reproduction is chiefly by seed, though fine and succulent stump shoots appear when a tree is cut down.

The timber has not been exported nor has it been used locally; the natives occasionally cut the bark for medicinal purposes, but otherwise apparently have no use for the tree.

Ochrocarpus Africanus? sp. of Allanblackia. African Mammee Apple, Mahogany (Calabar). Igoda (Benin); Ereruku, Edeng Edem (Calabar); Baulan Bolo (Degema, New Calabar); Okut and Otun (Oban, Ekoi).

Distribution.—It is found in the Calabar, Owerri and Ogoja provinces of Nigeria, occurring sparsely in the evergreen forests in several localities, where it takes the place of Khaya, which is not prevalent in such places.

Chief Characteristics.—It is a large tree, with orange-coloured bark, especially in young specimens, and a little scaly. In habit otherwise rather like Mahogany, after which the timber has been named. It is much harder and has little resin canals typical of the order. It is not attacked by white ants. It reaches a height of 100 feet, with a bole length of about 40 feet and a girth of 12 feet. The root spurns are only slight. The large, elongated, spherical-shaped fruit, with rough, pale orange-coloured rind, speckled brown in several places, is most typical of this tree. Generally speaking, it could easily be mistaken for Mahogany Entandrophragma by anyone not very familiar with both species.

Timber.—The sapwood is white, with a pinkish tint, and the heartwood a dark red, with small medullary rays as well as very prominent resin-like canals which, when dry, are filled with a yellow substance.

Silvicultural Qualities.—It is a shade-bearer, but likes a certain amount of overhead light in middle age. On the whole it is slow-growing, except for a short period when the chief height-growth is put on. A few stump shoots sprout when the tree is cut down, but the more common form of reproduction is by seed.

Utility.—It has not been felled for export, but the Public Works Department felled and converted a good deal at the Etehetem sawmill, and it was favourably reported on as a hard mahogany. It has occasionally been used by the natives for making canoes.

No botanical name. Oshusi (Ibo, Owerri).

Distribution.—It is found in the Owerri province of Nigeria. It is a comparatively common tree in the evergreen swamp forest.

Characteristics.—The timber is not over hard, but it reaches a height of 100 feet and a girth of 8 feet. The bark is smooth.

Silvicultural Qualities.—It is a shade-bearer and a comparatively slow-growing tree. The most prevalent form of reproduction is by seed.

Utility.—It has not been felled for export, but was used in the construction of the Imo railway bridge as piles.

Buronona (New Calabar).

This is a medium-sized tree of the Owerri province, and is found near the Imo, not far from the railway bridge. Several piles of the temporary bridge were made from the timber of this tree.

Ochrocarpus sp.?. Ebattan, Ehranezi (Benin); Buronona (New Calabar).

Distribution.—It is found in the Owerri, Benin (?) and Ondo (?) provinces of Nigeria.

Chief Characteristics.—It is a very straight, thin-stemmed tree, with several whorls of branches near the top of the tree, very much compressed together. The flowers are red sprays, which look very pretty at the beginning of the dry season. It occurs near the freshwater swamps, comparatively close to the sea. In many places it is almost gregarious in habit, more especially near Degema. It reaches a height of 100 feet, and a girth of 6 feet, often with a bole length of 50 feet.

Timber.—The sapwood is white and the heartwood is light brown; both appear to be equally durable. It is termite-resisting. It planes with a smooth surface; the grain is very fine. A red latex exudes when it is cut.

Utility.—It is chiefly used for door and window frames, and does not warp nor crack, even when put in green. It attains a large enough size to be used as piles, some of which were used in the construction of the temporary railway bridge at Imo. The natives do not use the wood, and it has not been felled for export.

Silvicultural Qualities.—It is a shade-bearer and a comparatively slow-growing tree, though on less wet soils it seems to grow faster. The more prevalent form of reproduction is by seed. Weak stool shoots also come up after the tree is cut down. The foliage is dense and persists for several years.

Bixaceæ.

Bixa orellana.

This tree grows well in the Olokemeji Arboretum. It is found up to a height of 10 feet, and is cultivated for the sake of its seeds, which yield the orange dye called “annatto.” The tree bears pods very freely. Samples were sent to the Imperial Institute in 1906 and were valued at about 5d. a pound.

Flacourtiaceæ.

Smeathmannia pubescens. Moyida (Yoruba).

It is a medium-sized shrub found in the Western Provinces.

Soyauxia sp. Ogohomeh, Oyohomeh (Benin).

This tree was found on the mountain slope above Ogabi in the Obudu district. The fruit is edible.

Soyauxia sp. Aye (Yoruba); Owowe, Owawe (Benin).

It is found in the Ondo, Benin and Ogoja provinces of Nigeria, growing at the edge of the evergreen forest. It is a medium-sized tree, with a bole length of about 30 feet and a girth of 6 feet; on the whole, it is of more slender build and habit than the Terminalia, to which it is apparently closely allied. The flower is very small, white and spherical, being only a quarter of an inch in size; it is most frequently seen lying scattered about in patches on the path or roadway, giving out a very sweet scent. The seeds are double winged, like Bougainvillea. The leaf is smaller than that of the Terminalia and the foliage generally less dense; the sapwood is white and somewhat wide, the heartwood of a light-brown colour, and on the border-line of being a hardwood. The wood is not very durable unless under cover; it is not very common, though where it is found there are a fair number of trees which would form a good supply of timber for local purposes. The natives do not use this wood, as they say it is liable to attacks by white ants.

Oncoba dentata (Oliv.). Parisha (Yoruba).

It is found in the Abeokuta province of Nigeria. It is a small, shrub-like tree, armed with moderately long thorns. It belongs to the evergreen forest zone. The flowers are large, white and conspicuous.

Oncoba glauca (Foster). Kakandika (Yoruba).

Found in the Olokemeji and Abeokuta provinces.

Oncoba spinosa (Rich). Kakandika (Yoruba).

This is a small, shrub-like tree found in the Abeokuta province of Nigeria. It is moderately common, and several hedges have been made with it in the Olokemeji Arboretum. The most distinguishing feature of this plant is the large, spherical-shaped white flowers. The petals are large and conspicuous, with a mass of yellow stamens in the centre. In habit it is not unlike the thorn; the ends of the twigs are armed with a short spike.

It stands trimming pretty well. Each year it flowers fairly regularly, so that it makes quite an ornamental plant. It bears green fruits with a conspicuous bunch of the old sepals at the top. This fruit is rather smaller than a tangerine orange, but quite spherical in shape, with a hard, woody rind.

Flacourtia Ramontchii. Abeokuta Plum. Oshere (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Flacourtia flavescens (Kew). Niger Plum.

Found in the Western Provinces.

Uses.—Edible plums, medicine and hedge plants.

Homalium, cf. H. Africanum (Benth.). Atu or Abo Ako (Yoruba).

This is a hard-wooded tree of the Yoruba country, which is used to some extent locally. It is also found in Benin.

Being a shade-bearing and soil-protecting tree, it is of value in the forest, apart from the production of timber. It is a slow-growing tree apparently.

Lecythidaceæ.

Napoleona Whitfieldii. Ito (? Yoruba); Uruhe (Benin).

It is doubtful if these are the correct native names for this species.

Napoleona imperialis. Speckle-fruited Napoleona. Boi Boi (Yoruba).

It is found near Ode district, Oban and Igbeshe, in the Ibadan and Abeokuta provinces of Nigeria.

It is a deciduous shrub with pretty white flowers, very shiny leaves, which are alternate, and bears a spherical, orange-coloured fruit (with a russet-like surface having white lenticels scattered nearly all over it), which ripens in March at the Olokemeji Reserve.

This shrub protects and enriches the soil with its fall of leaves. Considering the attractiveness of the flower and the fruit, it is surprising that it has not more frequently been planted in gardens, where it should be placed in a shady corner. It is slow-growing, and does not need much light. It likes a moist, fairly deep good soil, especially near a river bank.

Native Use.—The stem is occasionally used for making hoe or axe handles, for which it is suitable, as the wood is comparatively tough, close-grained and hard. The knottiness of it is an advantage either for the handle or for fixing the hoe or axe head.

Napoleona Vogelii (Hook). Orokwa, Ogemme (Benin).

It is a common tree in the Calabar, Benin, Ibadan and Abeokuta provinces of Nigeria.

Chief Characteristics.—It is a medium-sized shrub-like tree, with orange-shaped fruit, though not quite spherical, having small white lenticels on the surface and roughness like a russet apple. It does not attain a girth of more than 3 or 4 feet. It is usually found in the mixed deciduous forests, though more often in clearings in the forests; however, it stands a good deal of shade. The wood is comparatively hard, but it does not reach much size. The tree protects and enriches the soil with its fall of leaves, and serves a very useful purpose as a shrub amongst the undergrowth of the forest. It might be planted in gardens, where both the flower, which is large and white, and the fruit would be admired. It usually bears a large number of both. It is rather a slow-growing tree. The natives use the wood for making matchet handles.

Napoleona Owariensis. Adere, Isiurem (Lagos).

Found in the Olokemeji Reserve.

Rhizophoraceæ.

Weihea sp. (Spreng). Odu (Yoruba).

This tree is found in tropical West Africa.

The flowers have an involucre of two bracteoles. The fruit is fleshy; seeds with an aril.

Weihea sp., cf. Africana. Odu (Yoruba); Itobo (Ibibio); Munon (Efik).

This tree grows near Lagos.

Rhizophora racemosa. Red Mangrove or Salt Mangrove. Egba Ibadudu (Jeb. Yoruba); Ehrodo, Ibadudu (Benin); Odo (Jekri).

Poga oleosa. Inoi Nut, African Brazil Nut. Iku (Yoruba); Inoi (Benin); Inoye (Efik); Ikoi (Oban); Inoi (Ekoi); Ekom (Ibo Owerri); Imonon (New Calabar).

It is found in the Benin (?), Owerri, Calabar and Ogoja (?) provinces of Nigeria, in the evergreen zone, both of the level and hill country. On the whole, it is more prevalent as the eastward side of the country is approached. In the forest its presence is usually indicated by the heaps of broken shells left lying near the roots of neighbouring trees, on the path or roadside. The reddish-brown interior and cross-section of the inner covering of the shell is a most typical feature. The nut itself is roughly spherical in shape, with a surface almost evenly covered with little nodules, giving the nut very considerable resiliency against cracking. It is nearly half an inch thick, and inside there are two or three kernels. Each of these is a chocolate-brown colour with thick (almost three thirty-seconds to one-eighth of an inch) red-brown shell. Each is about ½ inch long and rather more than ¼ inch thick. This thick shell quite spoils the flavour of the nut, which is sweeter and contains more oil than the Brazil nut. It can, however, be removed with a pen-knife. The trunk of the tree is light-grey, with comparatively thin cortex. It reaches a girth of about 12 feet and a bole length of about 60 feet. It usually forks at about 50 or 60 feet from the ground, and this is one of the typical features of the tree. The crown is rather open, with several main limbs and comparatively few branches. Another place where it is commonly seen, both in the Degema and Calabar districts, is in the old farms, standing as isolated specimens, or standards overshadowing all the secondary growth. It is one of the few trees that are preserved when a fresh clearing is made for a farm. The fruit is the shape of a large greengage, the fleshy part of which soon breaks away, leaving the hard nut inside. The fleshy pericarp is about a quarter of an inch in thickness.

The sapwood is white, tinged with pinkish stripes, and the heartwood pinkish-red, with very wide and numerous medullary rays, which are most numerous, and in fact more so than in any other tree, and are very typical of this timber. The wood is soft, splits well, is of somewhat open texture and rather fibrous grain. It planes up well with a smooth surface, takes nails well, and saws well. It is liable to be attacked by white ants. The sapwood is fairly narrow.

It is a moderately fast-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration only appears to be slight, chiefly owing to the fact, perhaps, that most of the nuts are gathered and eaten by the natives. It is somewhat exacting with regard to soil. It appears to like one that is somewhat rich, deep, moist and with good drainage. In waterlogged areas it becomes stag-headed. No plantations have been made of this tree.

The timber has not been exported, not has it been cut for local use. It appears, however, to be worthy of a trial as a substitute for light cedar or mahogany, especially from wind falls, which are not infrequent owing to the way it is left standing in the forests.

Native Use.—The nuts are used by the natives, and are considered very valuable, in the most out-of-the-way parts of the forest, as a source of food. They used to be sold in the Calabar market 250 for 3d. Further notes as to the oil-bearing properties of this nut will be found in the section dealing with the oil seeds and nuts.

Combretaceæ.

Terminalia sp. Yellow Terminalia, Black-bark Terminalia. Idigbo, Opepe, Epepe (Yoruba); Egoyn nebbi, Egoyn nikwi, Egoyn lukan (Benin).

According to the Yorubas this is the Idi of the forest.

Distribution.—It is found in the Ondo and Benin provinces of Nigeria.

Chief Characteristics.—It has a slightly fissured bark, increasing in age, light-brown in colour in youth, but darkening with age, almost appearing black in the distance, rather forming a criss-cross pattern. It flowers in May with small spikes or thin, stiff racemes, each with little yellow balls of staminate flowers. It has a compressed crown of two or three whorls of branches, but not so typical as that of T. scutifera. It is, however, much more widespreading, chiefly due to the fact that the tree on the whole is shorter and stouter than T. scutifera. The trunk is much more cylindrical, and the root spurns are very slight, and not buttress-shaped as in T. scutifera. The contrast between the light-green foliage and the dark-coloured bole is so great that the tree is quite unmistakable in this respect. The only one at all similar in this is False Shea Butter, Mimusops Djave, but even the trunk of this one appears lighter than the former. The slash is dark-brown, almost black, on the outer edge and yellow on the inside. The fruit is not unlike a large hazelnut, but the shuck is of looser build, and the interior seed can be more easily seen than in the case of the nut.

The sapwood is a faint yellow colour and the heartwood a good yellow. It is of the hardness of an ordinary softwood, with a straight, even grain and somewhat open pores. It planes well, takes nails, splits very easily and saws well. For outside work it is not durable unless very thoroughly dried. For interior fittings it is very durable. It is liable to attacks by termites outside. It seasons well, with only a small amount of shrinkage and slight liability to warping.

It is a fast-growing, slightly shade-bearing tree, with strong soil-protecting and soil-improving qualities. Natural regeneration appears to be fair. It sprouts from the stump, but is not very strong. It likes a good soil, with fair drainage but a good deal of moisture. It will stand a certain amount of flooding. It is occasionally almost gregarious. No plantations have been made with this tree. It reaches a girth of over 14 feet and a bole length of about 70 feet.

The timber has not been cut for export, but occasionally it has been sawn up for planks for local use. It deserves, however, a further trial for export as a floor-board and for local use for a similar purpose. There are comparatively large supplies, and the dimensions of the tree are such that large planks and boards could be cut out of it.

Native Use.—The tree is occasionally felled for making canoes, but it is not taken unless there is a shortage of other harder kinds.

Terminalia sp. Orange-barked Terminalia. Ayo, Aiyo (Yoruba); Ayo, Ulazo (Benin).

Distribution.—Ibadan and Abeokuta provinces of Nigeria. It is one of the typical trees of the mixed deciduous forest zone, though it appears to be confined to certain localities, such as the Olokemeji Forest Reserve and other places.

Chief Characteristics.—Moderately thick bark, rather reminding one of Triplochiton, but with a certain amount of roughness and slight fissures. The crown is very pointedly oval and long, the leaves appearing only slightly terminal and not typically so. The branches tend to flatten out in old age, though they are slightly pendulous at the tips. The bole reaches a girth of about 10 feet and a height of 50 feet. The light patchy, orange-coloured bark is a most typical feature of this tree. Satinwood is the only one at all similar in this respect, but it is much smoother.

Timber.—White, with a faint yellow tint; the pores are much shorter than those of the other Terminalias, such as T. scutifera and Togoensis. The grain on the whole is finer and of closer texture. The timber is somewhat harder than either T. scutifera or T. sp., but not so hard as that of T. Togoensis. It planes well, takes nails, saws easily, but does not split so well. It is attacked by termites, but is durable for interior work. It is somewhat more brittle than T. sp.

It is a moderately rapid growing, light-demanding tree, with soil-protecting and soil-improving qualities. Natural regeneration does not appear to be good. It sprouts, but poorly from the stump, and if at all shaded dies away. It likes a moderately good soil, with a fair amount of moisture and depth.

The timber has not been cut for export, and only occasionally has it been felled for cutting into planks for local use. It deserves, however, a trial as a local flooring board. The available quantities so far discovered are not large enough to justify its trial as an export wood.

Utility.—The wood is used for planks and for canoes. It is likely to furnish timber for the home markets.

Local Use.—It has been used for making canoes, and also for sawing up into planks for house-building.

Terminalia scutifera. Shingle Wood. Afara (Yoruba); Oaha Egoyn, Egoyn nufwa (Benin).

It is a common tree in the Calabar, Ogoja, Owerri, Warri, Benin, Ondo and Abeokuta provinces of Nigeria.

The chief characteristics of this tree are the thin and far up-reaching root flanges and its thin, grey-coloured bark. It attains a height of about 200 feet and a girth of about 16 feet. The bole length often exceeds 100 feet. The crown is compressed and flat, with few main branches. It is usually found near water.

The timber is light-brown to almost yellowish-white, with darker streaks. The sapwood is almost white, but when dry is barely distinguishable from the heartwood, though when freshly cut the heartwood appears drier, and thus shows up against the damper sapwood. The wood is soft and planes easily, though not always giving a smooth surface. It is also easy to saw or cut with a chisel and splits well. It is attacked by termites.

On the whole the tree is a light-lover, and even the young self-sown seedlings only grow in comparatively open places near rivers, where there is no shade directly over them, though there may be trees to one side or the other. It is one of the typical trees of the evergreen and mixed deciduous zone, growing always on damp and deep soil. Natural reproduction by seed is good. Stool shoots grow, but do not persist for a great length of time. It often forms small pure groups in the secondary forest, and in suitable localities tends to be more prevalent in the secondary than in the primeval forest.

In Nigeria it has been used as planks, but is not considered very good. On the Gold Coast it has been used for shingles.

The natives occasionally use the tree for making canoes, also for bowls, plates, and native doors in the Benin country, but owing to its softness it is not considered of much account.

In figure No. 108 there is a picture of a very large specimen found in the Ikrigon Forest Reserve.

Terminalia Togoensis. Dry-zone Terminalia. Idi, Idi Odan (Yoruba).

Found in the Oyo, Benin and Ogoja provinces of Nigeria. It is a very common tree, with slight foliage and small stem, which is usually forked about 10 feet from the ground. The slash is yellow and almost dry, which is most typical of the tree.

The wood is soft, though harder than most of the other Terminalias. It works easily, but does not split well. The sapwood is white and the heartwood of a pale yellow colour. The bark is rough and widely fissured. Natural regeneration by seed does not appear to be good, though stump shoots appear when the tree is cut down. It stands a considerable amount of fire, but it is a light-loving tree.

The local people find the stem useful for house-building posts, as it is comparatively durable and forked in shape.

Terminalia avicennioides.

It was stated it was found in the Calabar province.

Terminalia Brownii. Inya joko (Yoruba).

Found in the Abeokuta province.

Combretum racemosum. Ogan pupa (Yoruba); Akoso, Orsorsor (Benin).

Combretum Lawsonianum. Ome (Benin).

It has red flowers and is found at Agege.

Combretum mucronatum. Okan pupa (Yoruba).

It is found in the Mamu Forest.

Combretum Zenkeri. Ogan (Yoruba).

It is found in the Yoruba country.

Combretum micranthum. Okan (Yoruba).

It is found in the Yoruba country.

Combretum glutinosum.

Combretum paucinervium.

Combretum Hartmannium.

These are climbing Combretums found in the Yoruba country.

Anogeissus leiocarpus (G. and P.). Yoruba Chew-stick. Ayin (Yoruba).

Distribution.—It is found in the Oyo and Abeokuta provinces of Nigeria.

Chief Characteristics.—This tree reaches a height of about 70 feet in favourable localities and a girth of 9 feet. With its birch-like foliage and the drooping and sweeping of the pendulous branches in old age, it is certainly the “Lady” of the African “open woods.” The little spherical fruits cover the ground in the early part of the dry season. The comparatively smooth bole, giving way to small scales of light-brown bark as the tree gets older, is a typical feature. It is often forked, especially low down. The bole is thin and slender in build, with upward tending branches, also very slender in build, but dark in colour. A blackish gum exudes when it is cut. The slash is yellow before the gum runs out.

Timber.—The sapwood is yellowish-white and the heartwood dark-brown to almost black in some specimens. It is hard, durable and termite-proof. It does not plane nor split well, takes nails with difficulty, but saws fairly easily.

Silvicultural Qualities.—It is a light-loving species, though in its youth it will stand a little shade. It is one of the first trees to appear on disused land, so long as the soil is good. Its foliage is a little acid, as it kills all grass, even Ekon, and for this purpose is invaluable as a tree for admixture with more valuable species. It is somewhat exacting as to soil.

Once it gets started after being planted, or as a self-sown seedling on good soil, it is a rapid-growing tree, which is only hindered in its growth by the annually recurring grass-fires. Wherever it is protected it develops into a straight-boled, large tree. The branches are very persistent, so that close planting is most necessary. Several plantations have been made with this tree.

Utility.—The tree is burnt for its ashes for fixing native dyes; the roots are used for chewing-sticks, and the bark is used medicinally by the natives.

It yields a good firewood which gives great heat. The smaller poles make very useful hut-building timber, as it is so often forked.

It should find a place as an avenue tree, owing to the delicate green, the drooping nature of its foliage, and the moderate amount of shade cast on the road.

The timber has not been tried for export, but with its dark black and sometimes streaky coloration it is worthy of a trial. Locally it has occasionally been cut for planks and for house-building. It is not liked because it is so hard. The sapwood is rather wide. The timber is sometimes rather knotty, especially containing dry knots. It is sometimes attacked by a large borer, making large holes in it.

Laguncularia racemosa. White Mangrove or White Button.

This species is found growing in the swamp regions, also on the coast. It yields timber, tanning, dyeing materials and medicaments.

Myrtaceæ.

Eugenia Owariensis (Beauv.). West African Allspice. Adere (Yoruba).

It is a common tree of the Olokemeji Reserve and the Abeokuta and Oyo provinces.

With its comparatively short bole (about 8 feet) and wide, almost spherically-shaped crown, it is one of the largest and most conspicuous of the dry-zone trees. The tree attracts the pigeons, but not so much as the wild fig. The flowers are very minute and insignificant. The fruit is very small and poor.

Reaching only a girth of about 4 feet, it does not yield very large timber. Although moderately hard and durable, it has not yet found a place in the local market. It is doubtful if it is termite-proof. It might be used for making boxes or for small articles of furniture in localities where wood is scarce.

It is a comparatively slow-growing tree, almost soil-improving, and of a light-loving nature.

Owing to its comparatively dense foliage partially shading the ground and thus killing the grass, it is a distinctly helpful species in the protection from fire of a dry-zone forest.

Natural reproduction by seed is only moderate, but stump shoots are strong, and it appears that root suckers also come up in certain places.

Eugenia Owariensis. Isinren (Yoruba).

This tree is found in the dry-zone forests—a spreading tree which flowers in February.

It yields timber, edible fruits and medicaments.

Melastomaceæ.

Memecylon sp., nr. Barterii.

It is found in the Olokemeji Reserve in the Abeokuta province of Nigeria.

Araliaceæ.

Cussonia Nigerica (Hutch.). Elephant Sugar-cane. Sigo (Yoruba).

This is an evenly and rather deeply fissured small tree of the dry-zone forest, which has in the main only a great tuft of large digitate leaves at the top of the stem. It is occasionally branched, when it gives an appearance of bearing all the leaves at the end of the stem. It is fairly common in the Olokemeji Forest Reserve of the Abeokuta province. This tree is one of the few digitate-leaved trees of the dry zone, and is certainly one with the largest; it is a fire-resisting tree. The natives occasionally use the stem for house and verandah posts.

Umbelliferæ.

Heptapleura Mannii. Found in the Oban Reserve.

Sapotaceæ.

Mimusops multinervis. Emido or Sleeper Wood. Ako Emido (Yoruba); Aganokwi (Benin).

This species is found in the Abeokuta and Oyo provinces of Nigeria; it is most common, and, in fact, forms almost half the crop in the belt of forest just on the south side of the railway four to six miles east and west of Olokemeji Station. The most distinguishing feature of this tree is the grey, thick, deeply-fissured bark. With its comparatively short bole and stout, crooked branches, it is not unlike an oak. It reaches a height of about 80 feet and a girth of about 15 feet. The root spurns are practically non-existent. The trunk tapers off quite abruptly after each series of branches. The crown is rather long and sometimes almost pear-shaped. The foliage is dense, and, for the size of the tree, the leaves are small. The flowers are small and white and conspicuous. The fruit is a small round nut, about half an inch in diameter. The leaves are a very dark green colour, but on the upper surface are often shiny.

The sapwood is white and, for the size of the tree, comparatively narrow. The heartwood is a deep red colour, which it retains even after the wood is dry. In sections from older trees it exhibits isolated white streaks, scattered here and there through the heartwood. This is made of a small mineral deposit which is closely allied to apatite. It is one of the hardest of the African woods and also the most durable; it splits most satisfactorily; it saws very cleanly, planes well, but owing to its extreme hardness takes nails with difficulty. It is termite-proof. It is just as durable in, as out of the ground. It burns with a fierce heat and, in fact, makes the hottest fire of any of the West African woods. The grain is very close, though sometimes it shows some figure. The knots in the wood produce some pretty “curl” effects.

The tree is a shade-bearing, soil-improving species of the mixed deciduous forest. It is very slow-growing, often not showing a greater height-growth than 6 inches per year. In its youth the branches grow more or less in whorls of three or four branches; these branches are very persistent. Natural generation good; it demands a good soil, but will stand a great deal of moisture, not to say flooding of the area for several months of the year. It flowers in February; the roots are comparatively deep-growing and there is a distinct tap-root. Some plantations have been made with this tree. It has been tried as a species to mix with ebony, and for this it seems suitable. In similar localities this species and ebony are often found.

Locally it is used as a house-building wood and occasionally for firewood. The timber has been cut up into sleepers and found to be most durable. When it was used in an unseasoned state, and in very dry territory, it was found to split—but this was scarcely a fair test of the wood. It has also been used as joists and for the framework of buildings, for which purposes it has proved very useful. Local carpenters have complained about its hardness, but usually the tools used have not been of such high quality necessary to give the best results when working on this wood.

The timber has not been used for export, but it deserves a trial, especially for railway sleepers.

Mimusops Djave. African Pearwood, False Shea Butter Nut, Cross River Nut. Aganokwi No. I. (Benin), Nyam (Efik).

It is found in the Benin, Owerri, Calabar and Ogoja provinces of Nigeria. It is also known as Cherry Mahogany. It is a moderately common tree in the evergreen forest zone, up to the end of the mixed deciduous forest zone. It is one of the giant forest trees, attaining a girth of over 30 feet and a height of over 200 feet; its bole is one of the straightest of African trees, the trunk often reaching over 100 feet without a branch. The crown is flattish and almost symmetrical in its roundness; it is formed with three or four main limbs spreading out at almost right angles to the trunk. The foliage is heavy and the sword-shaped leaves almost appear as though they were digitate, looking at them from the base of the tree. From a short distance the trunk looks almost black, but on closer inspection the bark is seen to be deeply fissured in a comparatively even lattice-work fashion. The slash is white and a thick white latex exudes. The root spurns are only slight, except in old age; otherwise the bole is one of the most cylindrical of African trees. (In illustration No. 100 a tree of about 8 feet in girth shows the very straight and even thickness of the bole.) The fruit falls to the ground about the beginning of November, and crushes on contact with the ground, showing the yellow floury pulp inside. The pulp has an extremely dry, sweet, almost nauseating taste and is inclined to stick in the throat. This huge fruit, the size of a man’s fist, is almost like a huge plum, with rough opaque surface and almost spherical in shape; inside, embedded in the pulp, are two, three or four lobed nuts, smooth and shiny on the more rounded face and rough on the other; in some respects they are roughly kidney-shaped when looked at sideways. The flowers are white and small; the tree loses its leaves for three or four days, when fresh ones come out again.

The sapwood is white and the heartwood of a rich red colour, often showing figured rosy grain; it is very hard, heavy and very durable, and is sometimes cross-grained, though usually the texture is fine and planes up with a smooth surface; it saws well, but is too hard to take nails, except in very thin wood. The sapwood is usually only two or three inches wide; the heartwood forms comparatively early in the life of the tree. On the whole, this tree has a more open grain than the other Mimusops.

Although the tree can stand a little shade in its youth, it is really a light-loving species: after the first year the height-growth rapidly increases when trees standing in a plantation have plenty of light. In illustration No. 93 some trees only twelve years old show how rapidly they develop under suitable conditions. None of these trees have yet come into the nut-bearing stage, but it appears that in favourable localities the trees will bear fruit between the fifteenth and twentieth year.

It is a soil protecting and improving tree—in fact, the thick leaves form some of the finest soil found in the forest. Natural regeneration is not usually very good, because the seedlings have little or no light, growing as they do from seeds which have fallen under the parent tree. Duika and various other animals spread the seeds in old farms where the trees have a chance of growing up. The timber has occasionally been shipped to Europe and has been sold at Hamburg as pearwood at 6d. per superficial foot, but the more rosy and figured wood has also found a sale in Liverpool, as it sometimes looks almost like a pinkish mahogany; it is, however, by no means well known, and further trials with the wood should certainly be made. Small consignments of the nuts have been exported from the Cross River and sold in Liverpool as a substitute for Shea nuts; they are found to be of a similar nature and of similar value for making an edible oil. The original cost was rather high, so that the nuts did not yield a profit on the transaction; however, with greater quantities being brought the cost should not be so high, and also, since this first experiment was made, the price of all oil nuts has risen enormously, so that at the present time there is an ample margin between the cost of production and the selling price. In the Cameroons the Balong natives dry the nuts, which they split open in two pieces, pick off the thin shell and boil out the thick buttery-like substance, which is used for cooking.

On our tour through their country we also tried it in place of lard, and found it quite suitable and quite pleasant to the taste and only about half the cost. In Nigeria, only the Oban people apparently know anything about making this butter from the nuts; in other parts it is quite unknown. The tree is not felled, but, on account of its size and all-inspiring form, is considered “Ju-ju”; pieces of the bark are chipped off and used as medicine to increase a person’s strength.

By the way, the constant cutting away of the bark at the base of the tree and the continual struggle of the tree to overgrow these wounds causes the grain to grow quite unevenly and wavering, thus forming figured wood.

Mimusops lacera. Benin Pearwood. Aganokwi (Benin).

In 1906 samples of this timber were sold in the Liverpool market as mahogany of a good, rich colour. It is found in the swamps near the Osse and Cross Rivers.

Dumoria Heckeli (A. Chev.). Oban Mahogany.

It is found in Tropical West Africa. It yields a fair timber. An immense tree of the Oban Reserve, similar to Mimusops Djave.

Omphalocarpum procerum. Ikassa (Benin), Apassa, Ukpassa (Efik).

It is found in the Calabar, Benin and Ondo provinces of Nigeria.

It is a common tree of the evergreen forest. It reaches a height of 60 feet with a girth of 28 feet. The bole is short and the crown long, but narrow. The huge, flatly spherically-shaped fruits, quite 9 inches in diameter and 6 inches thick, are most characteristic of the tree. These protrude just from the trunk or heavy branches with little or no stalk. The depression in them, top and bottom, is quite an inch deep. There are about sixty seeds inside, more like nuts. The leaf is large.

The sapwood is white and heartwood is brown-red. It is very hard.

It grows slowly and stands the shade. The seeds germinate well. It does not sprout from the stump nor do root shoots appear. Elephants and other animals, porcupines especially, eat the fruit.

The seeds are used in playing Ikbo, a Benin game. The seeds also are used, tied in front of Apata sticks, for making a musical instrument, or tied to the ankles of small boys to make a noise like a rattle when they start to walk.

Butyrospermum Parkii. Shea Butter Tree, Dry-zone Oak. Emi-emi or Emi-gidi (Yoruba).

This is one of the most prevalent trees of the Oyo province of the Southern Provinces of Nigeria and of the Borgu, Niger and Nassarawa provinces of the Northern Provinces of Nigeria. In places it is almost gregarious, but it is most commonly found in mixture with the Dwarf Red Ironwood, Lophira alata. In appearance it is most like a gnarled old oak, except that the base is often burnt and partially hollow. It is a large tree, reaching a height of about 40 feet and a girth of over 10 feet. The root spurns are comparatively short and rounded; the bole is short, attaining a length of up to 25 feet; the crown is almost spherical, but rather inclined to be broken up by three or four main branches; these are very thick in comparison to the size of the tree, but not so much in proportion as in the case of the Baobab. The bark is grey and very deeply fissured, more or less in criss-cross fashion, and even with deeper and wider fissures than that of the oak. The slash is white, and a small amount of thick white latex exudes very slowly from the cut. In the case of the Dwarf Ironwood scarcely any ordinary sap exudes and no latex. The leaves are about 10 inches long, a very dark green and shiny, and not unlike the hart’s-tongue fern, but somewhat broader at the end; the greenness of the leaves, their shininess, and the greater thickness distinguish them from those of the Dwarf Red Ironwood. The under surface of the leaf is whitish, sometimes almost grey; the flowers are white and come out in December; the fruit is like a small green plum and ripens in May. The leaves persist over one season. The green pericarp covering the nut can be eaten and is not unpleasant to the taste. The nut itself is not unlike a chestnut in its being brown and shiny; the shape, however, is more oval, with one comparatively sharp ridge.

The sapwood is white and comparatively wide; the heartwood is a rich dark-red colour; it is very hard and durable; it is termite-proof; it splits very badly, does not take nails well; it is hard to plane and is sawn none too easily. It does not warp or crack to any extent while it is seasoning under proper conditions; it burns with great heat, but rather less than in the case of Emido.

It is a rather slow-growing tree, with soil-protecting and soil-improving qualities; as a light-loving species takes up a good deal of space. Natural regeneration appears to be poor, and may be due to the fact that the flowers appear, or before the young fruit has only just set, as the annual grass-fires run through the open deciduous forests where this tree is found. On the other hand, root suckers grow in great profusion. It also sprouts well from the stump. It is one of the most fire-resisting trees, and the thick bark no doubt protects it from its worst ravages. It may be considered one of the most typical trees of the drier parts of the open deciduous forests. A few sample plots have been tried with this tree, but it does not stand transplanting at all well. Rodents such as the cut-grass (ground pig) are very fond of the nuts, and no doubt destroy a great number whilst they are germinating. Fire-protecting root suckers and other young trees have thus far proved the most effective method of increasing the number of mature trees. It does not appear to be very exacting as to soil, but no doubt the growth is best on moist alluvial flats so long as they are well drained.

Locally the most valuable part of the tree is the nut, from which the Shea butter is boiled out after three days; it is a general article of diet instead of palm oil, in those districts where the latter is hard to obtain. Locally, also, the largest trees are cut down and made into mortars for beating food; these fetch a price of 2s. 6d. to 3s. 6d. apiece; they are considered not only the most suitable, but also the most durable, except those made of the wood of the Oil Bean (Pentaclethra macrophylla). In other places it is used as a house-building timber.

As far as Europeans are concerned, the chief value of the tree lies in its nuts, which are either exported quite unprepared or in the form of the butter as the natives make it, in large elliptical-shaped sausages about 2 feet long and 9 inches in diameter. For these purposes it has become a regular article of commerce, and only lack of suitable means of transport prevents much greater quantities being collected and exported to the European markets. In Europe its most suitable use is said to be as a medium or inside substance of chocolate creams. The butter itself has a most peculiar and rather nauseating flavour, which is removed on its being refined and purified. The timber has not been tried for export.

Chrysophyllum sp.?. Round Star Apple. A species of Star Apple. Agoma (Benin).

The fruit is quite spherical and supposed to be larger than C. Africanum. It is somewhat similar to C. Kainato. The natives squeeze the fruit in order to eat it.

Chrysophyllum Africanum. African Star Apple or Edible Star Apple. Osangbalumo (Yoruba); Otien (Benin).

It is found in the Abeokuta, Ondo, Benin, Warri, Owerri, and Calabar provinces of Nigeria. It is a medium-sized tree, often found growing at the roadside at the edge of the villages or as an avenue leading up to them.

The most characteristic feature of this tree is the silvery underside of the leaf, which is formed by minute white hairs. In the fruiting season, another characteristic is the golden-coloured, pointedly pear-shaped fruit, which bursts on falling to the ground. A white latex exudes from the fruit; this latex is sucked out and is tartly sweet to the taste. Inside the fruit are five thin, elliptic-shaped seeds; these are brown and very shiny. Their position inside the fruit probably gave rise to the English name.

The wood is white and soft; it cuts easily and planes well, but does not split well. The grain of the timber is fine and the texture smooth. It is a moderately fast growing tree and the wood is not durable. The slash is white, and the tree exudes a white latex when cut; the foliage is very dense, and the dark upper surface of the leaves is a great contrast to the underside. It is a soil-protecting and soil-improving tree. The timber has not been exported to Europe. It is occasionally used by the natives for making “Ju-jus” such as the devil.

Chrysophyllum sp. Monkey Star Apple or Monkey Otien. Osang Palambi, Osang Edan (Yoruba); Ekuso (?), Ekpuro, Otiemmie (Benin).

This is a moderately prevalent tree in the Calabar, Ogoja, Benin, Ondo and Abeokuta provinces of Nigeria.

It is a medium-sized tree with a small leaf. It attains a girth of about 8 feet. The golden-brown of the underside of the leaves is most typical of this tree and makes it easily distinguished from Chrysophyllum Africanum; in fact, in passing through the forest this is one of the few trees having brown tomentose hairs on the underside of the leaf. The crown is broad and flat and heavy. The bole is not too long and is covered with a smooth light-brown-coloured bark.

The Benin native name means that it is the Monkey Otien, that is to say, not the one that men may eat. It is usually found in the evergreen forest.

The timber is white, light and soft, and is attacked by termites. It has not so far been cut for export or local use.

Native Use.—The fruit is sometimes eaten by the Benins.

Chrysophyllum albidum (Don.). White Star Apple. Osum Agbalumo (Yoruba).

This is one of the Star Apples of the Yoruba Forest, where it is found chiefly in the Abeokuta province. It is not very prevalent. The fruit is not so esteemed by the natives as that of Osangbalumo. The bole is somewhat straighter and less branched than that of C. Africanum. The wood is white and soft; the stem is not absolutely round, being somewhat fluted at the base, with narrow and thin spurs which extend 4 to 6 feet up the stem. The natives occasionally use the wood for household utensils. It has not been cut for export.

Chrysophyllum Welwitchii.

This so-called Forcados Star Apple was found in the forest just behind the station of Forcados. It is not a very common tree.

Malacantha sp. nov. Akala (Yoruba).

It is found in the Olokemeji Reserve and neighbouring parts of the Abeokuta and Ibadan provinces. In many places it is very prevalent, though it does not grow actually gregariously. It reaches up to a medium size. The bole does not exceed a length of much over 15 feet and a girth of 5 feet. With its four narrow, somewhat long (up to 4 feet) buttress root spurns, the base of the stem forms a rather irregular shape. The bark is roughish and scales off to a slight extent as the tree becomes older.

The leaves are inclined to be placed at the terminals of the shoots and twigs, and the main veins are very prominent, giving the impression that the leaf has only comparatively recently opened. The leaf is a little rough to the touch, and rather dry and thickish. It is a distinctly yellowish-green colour. The foliage is very sparse.

With its none too straight stem and comparatively slight amount of foliage it presents a poor appearance.

The wood is of a pleasant light-yellow colour and comparatively hard. It planes up with a smooth surface and saws easily. It does not take nails well, nor does it split easily. It is termite-proof.

Natural regeneration appears to be slight, but stool and root shoot reproduction seem to be strong. The seeds are very small and appear like little round, spherical nuts. Although it will bear a slight amount of shade in its youth, it is a light-loving species later on.

Occurring as it does in the mixed deciduous forests, near the lower edge of the dry-zone vegetation it should prove a useful tree, especially as it is comparatively fire-resisting.

Although comparatively slow-growing it attains sufficient size to be cut up into verandah-posts and banister rails and uprights.

On the whole, quite a respectable quantity of timber could be obtained in the aggregate from the large number of trees found growing in the forests.

Pachystela cinereum (Pierre). Osan odo, Orban igba (Yoruba).

Found in the Abeokuta province.

Ebenaceæ.

Diospyros Mombuttensis, syn. Sinensis. Walking-stick Ebony or Yoruba Ebony. Ogan pupa, Aggan Egbo (Egba) (Yoruba); Ungungmekkan (Benin).

It is a small tree with reddish-coloured stem and very thin, scaly bark, often branching near the base and usually forming several stems up to 18 inches in girth instead of one main stem. It has a large, alternate leaf, with large leaf scars, amounting to projections from the twigs. The fruit is like an acorn, but of reddish colour, with a very small, low-rimmed cup. The twigs are reddish colour too, which is most typical of the tree.

It is common in the Benin, Abeokuta, Ibadan, Oyo and Ondo provinces of Nigeria.

Timber.—Very hard, whitish-brown wood.

E. Use.—Walking-sticks, as it often grows forming a natural handle.

Native Use.—Walking-sticks.

Diospyros sp. Benin Ebony. Owegbo (Benin).

A medium-sized tree, yielding a black ebony, which is prevalent in the Benin forests. The bark scales off like D. atropurpurea. It is a larger tree, though, than the last named. It likes the dense forest with a deep, damp soil.

In proportion the sapwood is white and very wide.

The tree is slow-growing, shade-bearing, with soil-protecting and soil-improving qualities. Natural regeneration is weak.

The timber has not been exported, nor has it been sawn up for local use.

Native Use.—Firewood.

Diospyros mespiliformis. Monkey Guava or Yoruba Ebony, Kanran, Etini (Yoruba); Igedudu (Benin).

From the similarity of its fruit to a medlar it obtains its botanical name.

It is found in the Abeokuta and Ibadan provinces of Nigeria, in the mixed deciduous forest zone. In places such as the Olokemeji Forest Reserve and neighbourhood it is very prevalent and almost gregarious in habit. As regards height, and almost always as regards girth, it is the largest of almost all the ebony-trees, with the exception of one species found near the Niger, reaching a girth of over 14 feet and a bole length of 70 feet. At the pole stage, and as it gets older, the bark is evenly fissured, vertically and horizontally, breaking up into small black-edged sections of about 2 inches long and ½ inch wide. Until it is much over 2 feet in girth the cortex is smooth, dark-green or black. After this it becomes rather rough, with small fissures. Although often very cylindrical in shape, the bole sometimes has very considerable taper—in fact, more so than many other trees. The branches come out almost at right angles to the stem and are very persistent, still remaining as short snags for many years after they have been broken off by storms or other agencies. The leaves are smallish and lanceolate in shape, and almost appear to be silvery on the under surface and very dark green on the upper surface. The thinner branches appear silvery-grey, though they are very similar, but thinner in comparison to M. multinervis, which are found in the same locality growing side by side. The leaf has a few fine veins. The fruit is flatly spherical, and is like a little medlar with its russet-brown rough surface and the dried-up sepals of the flower on it. It is, however, larger than than of Multinervis.

The sapwood is white and narrow and the heartwood dark-brown to black, sometimes even green-black. It is very hard—in fact, almost the hardest of all African woods, with perhaps the exception of Yoruba Ironwood, Red Ironwood, and African Greenheart. It splits fairly well. It is inclined to be brittle, especially in timber from larger specimens, planes well and saws well, but is difficult to nail. It is termite-proof. Occasionally a large boring beetle burrows into the wood when it is lying on the ground. However, the grubs which do this damage are considered a delicacy by the natives, so that wherever found they are soon collected and eaten. The younger tree grows with branches more or less in whorls, but not so regular as those of M. multinervis. When fresh it is liable to warp. It keeps its colour better than most of the ebonies. It occasionally shows a little figure. In proportion it has the largest heartwood of any of them, and for this reason is a most valuable tree.

Diospyros Kamerunensis. Cameroon Ebony.

This tree has been found in the Boji Hills Forest as well as in the Cameroons. Although not of great size, it yields a comparatively large and black-hearted ebony. The fruit is much larger than that of most other species. It is comparatively prevalent at an elevation of about 1,000 feet in the Boji Hills. Up to the present it is doubtful if it has been worked at all. The natives have no use for the tree.

Diospyros Barteri. Ebony Nut or Yam Stick. Ivioha (Benin).

Small ebony-shrub of the Benin province of Nigeria, found near Okomo in rather moist ground. The natives have no use for the wood.

Diospyros bipendensis. South Cameroon Ebony.

It is supposed to be found in the Oban Reserve.

Diospyros crassiflora. Benin Ebony. Aborkpor (Benin).

It yields the black ebony of the Benin country and is somewhat prevalent. Found in the Benin, Abeokuta and Onitsha provinces of Nigeria. A tree with a small leaf.

It forms almost pure groups or even small stands, of half a mile and less in extent, near the banks of the Niger. It can stand swampy ground. It used to be cut in the Onitsha district.

Diospyros sp. Benin Ebony. Isanhianme or Ehrenyegbo (Benin).

A common tree of the Benin province of Nigeria. It is supposed to yield a good ebony. It does not reach a very large size. It is a soil protecting and improving tree. Locally it is used for house-building.

In 1906 samples of this timber were sold in the Liverpool market as mahogany at 1s. 6d. per cubic foot. Since that time it has not been exported.

Diospyros atropurpurea (Gurke). Brown Ebony. Igedudu (Yoruba); Igedudu (Benin).

It is a small tree, attaining a girth of about 4 feet. The heartwood is usually brown with black streaks, giving it a curious and diverse streakiness, not unlike black marble or Indian Blackwood. The flower is reddish-purple coloured and quite conspicuous, growing out of the upper surface of the twig without a stalk of any kind. The bark is almost black and peels off in very thin, oblong-shaped flakes; the cortex underneath is green. In old age it is hollow at the first branch joint.

It is found in the Benin and Abeokuta provinces of Nigeria. About one-third of the diameter of a mature tree is heartwood. Apparently a slow-growing tree, though none have been planted. It is a shade-bearer in the evergreen and mixed forest; natural regeneration is not good. A large cerambix or other borer makes finger-thick holes in the sap and heartwood of old trees.

It should be an export timber of value, but it was only valued at £5 to £10 a ton in 1906. It has been used for mirror frames.

Native Use.—For firewood in the Benin country, where it is considered very good.

Diospyros suaveolens. Benin Ebony. Oohoo (Benin).

It is a small-sized tree, with very small heartwood and a small, oblong, almost lanceolate leaf. The bark, which is quite black, has slight fissures and is much harder than that of D. atropurpurea.

It is prevalent in the Benin country, Nigeria.

It likes to grow near water, but not in a swampy place. It is a slow-grower and shade-bearer, being found as an undergrowth in the high forest. It is not attacked by white ants. The wood is hard and durable.

Native Use.—It is used for house-building as rafters, as well as for axe-handles of any kind. Small trees are used for making bows (long) for shooting birds.

Diospyros verrucosa.

This tree, although named from the Cameroons, is found in the Abeokuta and Benin provinces of Nigeria. The twigs are very rough compared to the other species.

Diospyros dendo?. Cross River Ebony. Ebubri etu, Obiliteto (Efik); Itiuyang (Oban, Ekoi).

It is a medium-sized tree with dark-green, smooth bark, with large lanceolate leaves and strong upward-spreading branches, which makes the bole shorter than it would otherwise be. The fruit is almost pear-shaped, containing four long, thin, wedge-shaped seeds, brown outside and white inside.

It is found in the Calabar and Ogoja provinces of Nigeria, in the evergreen forest zone of the hill forests.

The crown is rather irregular in shape, being supported with two or three main limbs from the bole. It reaches a girth of about 6 feet and a bole length of 12 feet.

The sapwood is wide and white and the heartwood black. The tree is occasionally attacked by a large borer, which makes large holes nearly ¾ inch in diameter. The timber is very hard, but if the tree is killed by fire it becomes a little more brittle than is usually the case. In old trees which may be left lying in the forest, the middle of the heartwood often decays away with ground-rot. It planes well and saws well. Nails often split it. It splits moderately well, especially when free of knots.

It is a very slow-growing, shade-bearing, soil-protecting and soil-improving tree. On the whole, it is more exacting as to soil than most other trees, being usually found on a good loam rich in humus, which is moist and with fair drainage. Natural regeneration is none too good. Stump shoots are very weak, and often do not occur. It has not yet been planted. It is very susceptible to fire—in fact, more so than perhaps any other tree. The timber has been exported for many years from Calabar, but of late in decreasing quantities, owing to the exhaustion of the nearer sources of supply, and to the fact that only small billets under 3 feet in length, not square, and only 3 or 4 inches in cross-section were cut. The usual native method of procedure is very curious. On making a clearing for a farm, any ebony standing there gets killed with the fire, and having comparatively few roots and being very heavy, the tree falls down. Before abandoning the farm the native may put a mark on this tree, or at any rate make a mental note of its existence. After a year or two, if he is in need of money to buy clothes, or wishes to purchase anything, he goes back to this old farm, finds this tree, perhaps externally somewhat charred, and perhaps the centre of the heartwood rotted away; he proceeds to cut it into lengths of about 10 or 12 feet. These he then splits lengthways into segments with a rounded side of about 5 inches, the two split sides about 4 inches, and the inner surface about 3 inches. In order to get these long pieces of suitable dimension to carry to the nearest factory or trading station, he cuts them into three or four billets; two or three of these, according to weight, are tied together and carried to the factory. It is sold by weight, and sometimes 200 billets go to the ton, though a smaller quantity of a larger size would be better and secure a better price. This method should be compared with the superior one adopted by the natives of the Cameroons. Compared to the usual price of £6 or £7 per ton for Calabar ebony, Cameroon wood usually fetches £10 to £12.

Diospyros xanthochlamys. Okahimi (Benin).

This is one of the Benin ebonies and is not very prevalent. It is said to yield a good ebony.

Maba Mannii. Benin Maba.

It is a common tree in the Benin and Ondo provinces of Nigeria. It only reaches a girth of 4 feet and a short bole of about 10 feet. It is much branched, even low down, the branches being persistent and crooked. The leaves are small, rather less than ebony itself. The leaf is really a long, pinnate one, with thirty pairs of pinnæ. The fruit is white, soft and oblong, with small seeds.

The tree has a white sapwood with a black heartwood, rather small in proportion to the size of the stem. It does not split well. Termites do not attack it, but occasionally the gigas borers make holes in it. It grows slowly and stands a good deal of shade. It sprouts well from the stool and the seed also grows fairly well. It grows in the damp, deep soil and does not stand fire at all. It belongs to the evergreen forest zone.

This tree has not been cut for local use or exported to Europe. It is used as firewood, and is considered better than most other woods, even Ohia, Celtis sp.

Oleaceæ.

Schrebera Golungensis. Hard Yellow Wood. Opele (Yoruba); Udegwoga (?) (Benin).

It is found in the Abeokuta province of Nigeria, Olokemeji and Ilaro Reserves.

It is a large tree, reaching a girth of about 10 feet. The smooth, light-green bark with yellow patches differs from the Celtis species, which is rougher, and the Afrormosia species, which is orange-red and peels off. The leaves are small for the size of the tree. The crown is narrow and long and the branches forming it slender. The curious small pear-shaped dehiscent fruit, showing four oblong niches for seeds, is most typical of the tree. In other respects the habit and build of the tree is similar to the Celtis species, especially with the root spurns slightly corrugating the base of the bole. It is not a common tree, but usually a fair number of specimens are seen in any locality where it has been found. The bole is very straight and free from branches for quite a height of the tree.

The timber is a dull-yellow colour, fine grain, of smooth texture and moderately hard. It planes to a smooth, almost shining surface. It scarcely shrinks or warps when drying.

It sprouts slightly from the stump, though the shoots do not seem to have much strength.

The timber has not yet been exported, though its valuable quality should assure it of a market. Sample planks used at Olokemeji proved most durable.

Native Use.—The fruit is used by the Yorubas for divining the future.

Loganiaceæ.

Strychnos densiflora (Baill.). African Strychnos Tree. Attako (Yoruba); Egbeda (Benin).

It is found in the dry-zone forest of the Ibadan and Benin provinces of Nigeria, where it seems to be very prevalent.

Chief Characteristics.—It is a small tree or shrub, up to 12 feet high, with small leaves and very hard wood.

It is of slow growth, but on the whole is a shade-bearer and soil-protecting and soil-improving tree. Natural regeneration appears to be poor.

It has not been planted.

Apparently the seeds have not yet been examined as to their value. The timber is too small for export or local use, except for hut-building.

Use.—The Benin natives use the stem for making snares for Duika and the branches for making brooms, as they are very tough.

Anthocleista nobilis. Ogugu, Sapho, Apa Oro (Yoruba); Orrimogungun, Oriweni (Benin).

It is found in the Ibadan, Abeokuta, Benin and Ogoja provinces of Nigeria.

It has huge soft leaves, and is one of the first plants to appear on a clearing in the dry-zone or mixed forests. In old age the leaf is much smaller, and the mass of white flowers along the uppermost branches is most typical of the tree. It is often almost gregarious, and in most places more than one tree is found in the immediate neighbourhood. Reaching a girth of about 3 feet, its stem does not exceed 20 feet in height. There are usually two or three main branches into which it divides. The wood is soft and white.

It is a light-loving, rapid-growing tree, which is soil-protecting and soil-improving in youth, but is too open in crown after a few years. It should, however, prove a useful nurse for superior species in the dry zone.

Native Use.—Firewood in places where wood is scarce.

Apocynaceæ.

Alstonia Congensis (Eng.). Pattern Wood, Stool Wood. Ahun, Awun, Ogudugbu (Yoruba); Ukhu (Benin); Ekuri Ebu (Ibo Owerri); Abo, Idu (Efik); Ofemm (Bembi); Etiap, Oguk (Oban, Ekoi).

It is a large tree, growing up to a height of 100 feet and 10 feet girth. The white lenticels on the bark are very typical of the tree, and give it the appearance of having a rust disease. The crown is formed of two or three whorls of branches and is very flat in old age. The tree grows always in whorls, though it may have more than one stem. In the distance the leaves appear to be digitate, but in reality three to seven are found to be growing out of the end of one stalk, all being much the same size. The crown is flatly umbrella-shaped. It has comparatively few branches. The root flanges are slight, soon merging into the trunk. At the base of the bole, however, they are not absolutely round in shape, but have two or three large ridges, sometimes almost subdividing it. The slash is white, with yellow spots. A chalky white latex exudes when it is cut, rapidly running down the stem like a streak of whitewash.

It is found in the Abeokuta, Ibadan, Ondo, Benin, Owerri, Calabar and Ogoja provinces of Nigeria in the evergreen and mixed deciduous forest zone. It is a very common tree throughout this region and is usually found growing singly.

The timber is white, there being little or no difference between sapwood and heartwood. When dry, it is very light and soft. It splits and planes easily, saws well, and takes nails easily. The grain is close and fine and very even in texture. Although dull, it works up to a smooth finish. It is attacked by termites. It is not durable in the open, but under cover it lasts quite well. In drying it is liable to shrink and warp a little, but with care this can be avoided. It seasons comparatively quickly. It cuts easily with a knife or chisel and might take the place of lime as a carving-wood. From its texture it should take stains very well.

It is a very fast-growing, at first slightly shade-bearing and latterly a light-loving tree, which thoroughly protects the soil and enriches it with its leaf fall. Natural regeneration appears to be good, as it sprouts well from the stump. It seems to like a good soil with plenty of moisture, and will even withstand floods. It is not fire-resisting. The crown and branches are liable to be broken with a high wind.

In 1906 samples of this timber were sold in the Liverpool market as a whitewood, but it was considered to be of no value. It deserves a further trial as a pattern-wood, comparatively large quantities being available. Locally it has not been sawn up for planks.

In Calabar the timber is used for stools, which are carved out of large solid blocks of this wood in one piece, without a joint.

Native Use.—In the Benin country the timber is used for doors and the roots for medicine.

The box of the musical instrument Asologun, a kind of zither, is made of this wood in the Yoruba country. The latex is used for mixing with real rubber latex of the Anyo or Funtumia elastica tree.

Voacanga Africana (Stapf.). Cloth Shrub. Dodo, Giwini (Yoruba); Igbo (Benin).

It is a common shrub-like tree in the Ogoja, Onitsha, Benin, Warri, Ondo, Ibadan and Abeokuta provinces of Nigeria. The tree is usually noticeable from its white wax-like, trumpet-shaped flowers, which have a very fragrant scent, and which very rapidly wither when cut. The bark is thin and extremely fibrous and hard to break, so much so that the natives of the Asaba district make grass-like fibre out of it and mix it with a silk fibre to make a very durable kind of cloth, which the natives wear. It grows in waste places and requires light. It sprouts well from the stump.

Conopharyngia durissima.

This tree is found in the Western Provinces. It is of a similar size to C. pachysiphon, and the timber is just as durable.

Conopharyngia pachysiphon. False Boxwood. Dodo? (Yoruba); Ibbu (Benin).

It is a common tree in the Calabar, Warri, Benin and Ondo provinces of Nigeria. A small tree, attaining a girth of only 4 feet, with a large leaf, bearing large spherical-shaped fruits in pairs. The large creamy-white, strongly scented flowers are conspicuous to both sight and scent. The bark, even in its younger stages, is covered with small yellow lenticels. The wood is hard and yellow in colour, and there is no difference between sapwood and heartwood. The latex has sometimes been used as an adulterant for rubber. It is a shade-bearer, and is found at the border of the evergreen and mixed deciduous forests.

The natives of the Benin country use the roots for medicinal purposes.

Farquharia elliptica. Onanisankianmon (Benin).

This is a member of the new genus of Farquharia found by Mr. Farquhar in the Benin province of Nigeria, near Ugumu. It is not stated whether the natives use this as a source of rubber or not.

Landolphia florida (Benth.). Rubber Vine. Ibugidi, Ibo-akitipa (Yoruba).

A vine found throughout Southern Nigeria, though most abundant in the dry-zone fringing forests and in the intermediate forests, and at Ottoa, Benin province. It bears white flowers having yellow centres.

Uses.—Milky juice is obtained from this vine, but it is not good rubber, and has no market value.

Landolphia scandens. Ibo (Yoruba); Ubamiogon (Benin); Otopoi, Otanta (Ibo Asaba).

Ilaro.

Landolphia Owariensis, var. rubiginosa.

Found Anwai River, Asaba district.

Landolphia Owariensis. White Vine Rubber. Ibo tabong (Yoruba); Ubamiogon, Ubgo (Benin); Otta farfridi (Ibo Asaba).

Found Benin City and Mamu.

Landolphia Senegalense. Ibo akitipa (Yoruba).

It is found in the Oyo province of Nigeria, and it is supposed to be one of the sources of vine rubber.

Landolphia Thompsonii (Chev.). Corrugated-fruited Rubber. Ibogidi (Yoruba); Ugbamiogun (Benin).

Abeokuta, Benin and Calabar provinces of Nigeria.

A vine growing abundantly throughout the rain and fringing forests. It has white flowers with yellow centres and a bright-yellow edible fruit. No rubber is obtained from it, but only a pasty mass from the latex.

Landolphia Petersiana. Large-fruited Landolphia.

Found in the Oban Reserve and Benin province.

Landolphia bracteata. Autopoi (Ibo Asaba).

Found at Idanre, Anwai, Asaba district.

Carpodinus hirsuta (Stapf.), var. djenge. Flake or Paste Rubber, Root Rubber, Brown Cluster, or Brown Medium. Ibo Ilecki (Yoruba); Uboto, Obo, Ubanakwi, Ake, Abache (Benin).

It is found in the Onitsha, Benin and Warri provinces of Nigeria. It has a mauve-coloured flower with a musk-like scent.

The rubber was bought near the Niger until the vines from which it was taken were destroyed.

Carpodinus Barteri, syn. Clitandra Barteri. Mauve-flowered Vine Rubber. Ibo (Yoruba); Akhe (Benin); Akwarri, Offonkwari (Ibo Asaba).

Anwai River.

Carpodinus fulva. Pear-shape-fruited Rubber. Ikwian (Benin).

Found in the Asaba district, Benin province.

Clitandra elastica. Brown Medium Rubber. Ubabikpan (Benin); Beckindanko (Hausa).

Benin province.

A vine of the dry zone, found in the Okwoga district and at Adani in Awka district. It also yields root rubber.

It yields a good rubber, sold on the Niger for 1s. 3d. to 1s. 6d. per pound (1911). Extracted by tapping and coagulated by boiling, also with salt.

Clitandra visciflua (Hall. Fil.). Ubake (Benin).

Found in the Benin province.

Clitandra Togolana (Hall). Ibo, Agba (Benin).

It is a large tree, up to 60 feet high (?). Olokemeji.

Clitandra cirrhosa. Oban Rubber.

This is one of the commoner vines of the Oban Forest Reserve. In recent years, owing to the low price of rubber, it has not been tapped to any extent. The cost of collection to the natives is rather high, with the extended preparations and amount of food they must take with them in this forest. Added to this there is the cost of the licence and the cost of taking it over the long distance to the market, so that they do not think it pays to collect this rubber.

Rauwolfia vomitoria (Afzel). Swizzle-stick. Iraigbo, Asofeyeje (Yoruba); Akata (Benin).

It is found in the Abeokuta, Ibadan, Ondo, Benin, Warri, Owerri and Calabar provinces of Nigeria, in the evergreen and mixed deciduous zone, where it is very prevalent.

It is a small tree of 12 feet in height and 18 inches in girth, with almost always four branchlets to each branch, forming regular whorls in this manner. It has a soft, thin leaf and a round, small green fruit. The stem is usually forked near the ground, and each side branch is forked again and the uppermost branches divided into four separate twigs, making thus a most convenient shape for a swizzle-stick. The stem is more or less dotted with a few white lenticels. The bark peels off very readily and cleanly with a knife, leaving the bare white stem, especially in the smaller branches.

The wood of the smaller branches is soft, showing a small pith in the centre, but that of the stem in the larger specimens is comparatively hard, and more like an inferior type of boxwood. The sapwood is usually a little softer than the heartwood.

It is a moderately fast-growing, shade-bearing, soil-protecting and soil-improving tree. Natural regeneration is good. It sprouts well from the stump, and a certain number of root suckers appear. It stands pruning well.

The tree does not really reach a large enough size to yield export timber, or to be of much value for local use. It is, however, commonly used as a swizzle-stick.

In places where building timber is scarce, it is occasionally used in house-building. It could be, and sometimes is, used as a live fence.

Polyadoa umbellata (Stapf.). Oak or Boxwood. Aini (Egba); Erm (Yoruba); Osu (Benin).

It is a medium-sized tree which grows to a girth of 4 feet. The young stem is easily recognized by the longitudinal strips of lenticels, joined together with the dark-green cortex, showing between each strip. When older, lenticels appear on the stem and it may be quite grey or white.

The wood is a dirty yellow colour and very hard, resembling box in the fineness and the hardness of its grain. It is used by the natives for making combs for the hair; these combs have six prongs about 6 inches long and are sold at 6d. to 1s. apiece. It is used for house-building, and is considered the most durable timber for this purpose; it is forked about 15 to 20 feet from the ground. The bark is used medicinally by the natives (Yorubas).

The leaves are a yellowish-green, gradually turning a rich dark-green. The small greengage-sized fruits appear in pairs at the ends of the shoots, and occasionally in threes, but this is rare.

It likes moist ground, though it will stand a long dry season, so long as it has the shade of other trees. It is a distinct shade-bearer, though it grows a fair height when it has a chance. The flowers are white and have a very pleasant smell.

Only a very small quantity of latex exudes when the tree is cut, and so does not give the impression of belonging to the rubber family of Apocynaceæ.

The sapwood is a similar colour to the heartwood. It is not always straight, but this is owing to its slow growth causing it to be amongst the dominated trees. In older trees the stem is usually quite white, except where the bark has been removed.

A sample was sent to England in 1914 and was said to be valueless as a substitute for boxwood. In 1906 samples were shipped to Liverpool, where it was sold as a species of oak at 1s. 9d. per cubic foot, but it was not considered as good as that obtained from Awaw, Eba, Lophira procera or Ostryoderris impressa.

Native Use.—The chief tree for all tool-handles and house-posts. The most durable kinds are in Egba, and they are not attacked by white ants.

Alafia Landolphioides. Ubamiagon (Benin); Ata frifridi (Ibo Asaba).

Found at Illushi, Asaba district, Oke Igbo, Ilesha district.

Carissa edulis.

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria. The fruit is edible.

Motandra Guineensis (A. D.C.). Bodekadun (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

It has not been used for making rubber.

Strophanthus Preussii. Elephant Poison. Isha gere, Isha kekere (Yoruba).

Found in the Shagamu, Lagos and Calabar districts.

A climbing shrub, attaining the height of 12 feet. The flowers are creamy in colour, deepening to orange, with purple spots and streaks.

Strophanthus hispidus (A. D.C.). Isha fere (Yoruba).

Found in the Ilesha district, Oyo province.

Holarrhena Wulfsbergii (Stapf.). The Male Rubber Tree or False Rubber Tree, according to the Yorubas, or sometimes known as the False Ireh Tree. Ireh-ibeji, Ireh-ako, Ako-ireh (Yoruba).

This tree being found in the Abeokuta and Oyo provinces of Nigeria, it is not very prevalent, nor does it grow in large numbers in any one place. With its smooth, dark-green bark, speckled irregularly all over with white spots and lenticels, it is easily distinguishable from the almost silver-white or grey beech-like stem of the true West African Rubber Tree.

At a height varying from 10 to 15 feet the bole sometimes divides and forms two very straight stems, one much smaller than the other. In the African Rubber Tree (Funtumia elastica) usually only one stem is formed.

Again, in its sparse and rather drooping foliage it is very different from the real rubber-tree. The leaves are much longer, more sharply pointed, and in fact more lanceolate than those of F. elastica. The foliage often gives the appearance of being withered or that the tree is drying up.

Large raceme-like masses of small flowers appear in February or March, which are much more prominent than those of F. elastica, these being more hidden among the leaves, although individually having larger blossoms. Later on, a thin round pod, nearly 2 feet in length, forms in pairs, which hang down and make the tree look most grotesque. On the other hand, F. elastica pods are stout and short and almost hidden by the foliage.

The tree reaches a girth of 36 inches and a total height of about 50 feet.

The slash is greenish-white, and a very little white, rather watery latex exudes from the cut. The wood is white, soft, planes easily, and splits comparatively easily. It saws fairly well and takes nails with comparative ease. It is not termite-proof.

It is a moderately fast-growing tree of a light-loving nature. Natural reproduction by seed appears to be fair. It sprouts slightly from the stump.

Being found in odd and poor places in the mixed deciduous forests at the edge of dry-zone vegetation, it should prove useful for temporary house-building purposes and for cutting up as cratewood for bananas, etc.

Pleiocerus Barteri (Baill.). Irena, kekere (Yoruba).

The fruit is very much like a Cola and fairly common in the forest. It is very sticky to the taste.

It is a medium-sized tree, in habit similar to the Cola-tree, and most people would classify it from its external appearance as a species of Cola.

It is found in the Benin and Abeokuta provinces of Nigeria.

Picralima Klaineana?. Agege (Yoruba).

Found at Agege, Yoruba country.

Oncinotis gracilis. Ornamental Rubber Vine. Allerle (Benin).

Found in Ogodo Dry-zone Forest.

Name unknown. Ikwian (Benin).

An uncommon tree of the Benin province of Nigeria. It attains a medium-size and bears large fruits. The wood is used as firewood.

Borraginaceæ.

Ehretia cymosa (S. and H.). Ija oke (Yoruba).

Found in the Olokemeji.

Cordia sp., ? Platythyrsa. Drum-wood Cordia. Ako Ledo (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria.

Cordia Irvingii. Acorn-like-fruited Cordia.

It is a medium-sized tree, similar to Cordia Millenii. It is found in the Abeokuta province of Nigeria.

Cordia Millenii. Omon or Omo (Yoruba); Omah (Benin).

This tree is found in the Abeokuta, Ibadan, Ondo, Benin, Owerri, Calabar and Ogoja provinces of Nigeria.

It is an irregularly shaped tree, often with more than one stem. The light-coloured bark, especially when it is scaly, often gives the impression that the tree is luminous at night. The leaf is large. It is a common tree in the Benin district, of medium-size.

It yields a softwood, which has a certain amount of resonance. The sapwood is white and the heartwood a mid-brown colour. It is not very durable, except under cover.

It stands a good deal of shade. It sprouts well from the stump. It bears fruit irregularly, and seedlings are scarce in the forest. The wood has not been exported, and none of its qualities so far assure it of finding a good market in Europe.

Native Use.—The natives use the wood for making drums.

Verbenaceæ.

Avicennia Africana. White Mangrove. Ogbun (Lagos); Ede, Eyhrodo (Benin); Odonumon (Efik).

It is found in the Colony, Ondo, Warri, Owerri and Calabar provinces of Nigeria. It is seen partly in pure groups, and also mixed more or less in groups with the other areas of Red Mangrove and Laguncularia sp.

It is a small tree, growing up to 2 feet girth and about 40 feet high.

The bole appears silvery grey and the branches very slender. The leaves are of a lighter green than those of the Red Mangrove. The aerial roots are smaller and not so extended as in the case of Racemosa. On the whole, it occurs in the quieter and less exposed localities, away from the sea, and it seems to appear only secondary to R. racemosa, which is the first tree to appear in the mangrove formation. The slash is white; the cortex is thin.

The sapwood is white and the heartwood a light brown when freshly cut. Is moderately hard, and durable when dry and used away from water. It is termite-proof. In structure it is similar to teak, being a member of the same family, but the grain is more open and the pores are considerably larger and longer, giving the wood a more open texture. It planes up with a smooth surface, splits well, takes nails moderately well and saws easily.

It is a somewhat slow-growing, at first shade-bearing, and later on a light-demanding tree. Natural regeneration is good, but it does not appear to be extending as fast as R. racemosa. It sprouts from the stump; root suckers and aerial root shoots grow in considerable numbers. On the whole, it tends to die out sooner when the ground becomes dryer than R. racemosa, and its area of distribution from the coast inland is much less wide.

The timber has not been exported, nor has it been sawn up for local use. For the natives this tree forms what is considered the best “salt bush” in the Jekri country. It is still used for the manufacture of salt, which is considered much stronger than and superior to imported salt. It is also used for poles, house-building, boat and canoe houses and wharves.

Vitex grandifolia. Ori (Yoruba); Owenkundignon, Oriri Ogikiomi (?) (Benin).

It is found in the Benin, Onitsha, Owerri and Ogoja provinces, in the open deciduous forest zone.

The digitate leaf is much larger than that of V. Cienkowski, and on the whole the tree is larger too, reaching a girth of 10 feet and a bole length of 30 feet. The fruit is rather larger, but similar in shape and taste to the former. The branches are very persistent, and coming out more or less in whorls from the bole, give the tree a most distinct appearance.

The sapwood is white and the heartwood at first light-brown, and then darker brown. It is rather more open-grained than the teak. It does not split very well, but can take nails; neither does it plane easily, but can be worked up to a smooth finish. It is very durable and termite-proof.

At first fast growing and later rather slower, it is on the whole a little faster growing than V. Cienkowski. It withstands the fires in an extraordinary manner, and only occasionally does the bole get so deeply burnt that the tree becomes hollow. It bears a large crop of fruit almost every year.

The timber has not been exported, nor has it been sawn up for local use. It deserves further attention than it has received up to the present, more especially as it is of the same family as the teak.

Native Use.—The fruit is eaten, and occasionally the smaller trees are used for house-building.

Vitex Cienkowskii. Ori, nla (Yoruba).

It is a medium-sized tree, attaining a girth of about 8 feet and a bole length of about 25 feet. The bark is rough, divided up with long, narrow vertical fissures, which are more or less regular in their distribution. The crown is spherical, somewhat widespreading, and usually occupies about half the height of the tree. The large, shiny, dark-green digitate leaf is most characteristic of the tree. The fruit, not unlike a large acorn without the cup, is edible and has a slight honey taste. It attracts the bees from far and near.

This tree is found in the Oyo and Abeokuta provinces of Nigeria.

Timber.—Hard, brown wood, very similar to teak. It is often rather knotty and sometimes cross-grained.

At first fairly fast-growing, later on it is rather slow. It is very fire-resisting, but does not thoroughly protect the soil. It has not been felled for export, nor has it been sawn up for local use. It serves a useful purpose amongst the dry-zone vegetation, and is one of the larger trees of that zone.

Vitex Fosteri. Ori-eta (Yoruba); Obuban, Ibang (Benin); Ogi (Calabar).

Chief Characteristics.—It is a medium-sized tree with thin, white bark and voluted stem, which is not overstraight beyond 15 or 20 feet, soft and fibrous; one of the common trees in the mixed forest, though also found in the evergreen forest. It has a thin, digitate leaf. It usually stands as one of the dominated trees in either forest. The leaves often look silvery, but this is an optical illusion, owing to their being so thin and white on the underside.

Distribution.—It is found in the Abeokuta, Ibadan, Jebu, Ode, Benin and Calabar provinces of Nigeria.

Timber.—It is a hard, white wood of even texture and smooth grain, which is apparently durable for interior work. It is somewhat like hornbeam, though not quite so hard. It works up with a smooth surface.

Silvicultural Qualities.—It is a shade-bearer, though, if planted pure, it is doubtful whether its foliage would thoroughly protect the ground, owing to its being so thin. Natural regeneration by seed is apparently good.

Use.—It would probably make good verandah-posts, door-frames and window-frames, but so far has not been tried. As there is plenty of it, proper supplies could be obtained in the provinces named.

Value.—At present doubtful, as it is an untried wood; however, belonging to the same family as teak, it should find a place amongst the valuable small timbers for local use.

Vitex diversifolia.

It has been noted from the Oban Reserve.

Clerodendron Thonningii. Egwa, Oriakuku (Benin).

It is an ornamental shrub of the Benin province of Nigeria, found near the Osse River.

Clerodendron Thompsonii. Egwa oviakuku (Benin).

A medium-sized shrub with woody stem found in the Benin province.

Clerodendron scandens (Beauv.).

It is a large shrub with hard wood of the Benin province of Nigeria.

Clerodendron volubile. Ebenote (Benin).

Found in the Benin province.

Clerodendron splendens (Kew). Adabi (Yoruba).

Ocimum viride (Willd.). Efinrin (Yoruba); Aramoho (Benin).

Found in the Yoruba and Benin country.

Scrophulariaceæ.

Cycinium camporum (Engl.). Arojoku (Yoruba).

Flowers white. Found at Obba on the Hill, Ondo province.

Bignoniaceæ.

Spathoidea campanulata. Red Tulip Tree. Oruru (Yoruba); Okokwi Okwekwe (Benin); Essenim (Efik); Osukaregigi (Bembi).

This tree grows in the fringing and intermediate forests. It is of medium size and has large trumpet-shaped flowers, not unlike those of the tulip.

Uses.—This tree is often used for ornamental purposes. Timber, edible seeds and medicaments are obtained from it.

Stereospermum acuminatissimum. Osualong (seed), Okwekwe, Aguana (Benin).

This is a somewhat common tree of the Benin province of Nigeria, and certainly with its red flowers it is one of the most handsome. It is not unlike the so-called African Tulip Tree, Spathoidea campanulata. On the whole, it is a smaller tree, with a round, almost spherical crown; the wood is soft and white and not durable. It bears a large number of seeds, but few appear to germinate. It sprouts feebly from the stump, is a light-loving tree, and also a soil-protecting and soil-improving species. It deserves greater attention for planting in gardens and at the edges of recreation grounds of all sorts.

Stereospermum Kunthianum (Cham.). Ayagdo (Yoruba).

This tree is found in the Abeokuta province and Erin, Ilesha. It is very similar to the tulip-tree, but has a more orange-coloured flower.

Kigelia Africana. Sausage Tree. Orora, Pandoro (Yoruba); Ogiahimi, Esiskwi (Benin).

It is a common tree of the Ogoja, Owerri, Onitsha, Benin, Ondu, Ibadan and Abeokuta provinces of Nigeria. The most typical feature of this tree is the long sausage-shaped fruit, which hangs by a stalk about 10 inches long; the flowers are red, the leaves large and open. It is a small tree, often very much branched. It is usually found in old clearings at the edge of the mixed deciduous forest. The wood is not durable. The natives use it for fences, and the roots are mashed and used by Benis for cuts in the fingers. The bark and fruit are also used medicinally by the Yorubas.

Markhamia tomentosa. Iru, Aya, Iwe (Yoruba).

It is found in the Abeokuta province of Nigeria, in the mixed deciduous forest zone.

It is a tree 4 to 6 feet in girth, with a large leaf having five pairs of pinnæ, the lowest being very small, like stipules. A deciduous tree bearing small fruit. A very common tree.

The timber is a soft, white wood, which is not used. It is attacked by white ants, and is not durable except under cover.

The tree is a light-lover, quick-growing, and non-soil-improving. Natural regeneration is moderate, so that it does not spread too much. The tree has not been felled for export timber, nor has it been cut for local use.

Newbouldia lævis. Benin Ju-ju Tree. Akkoko (Yoruba); Ikhimi (Benin).

It is found in the Calabar, Ogoja, Owerri, Warri, Onitsha, Ondo, Benin, Ibadan and Abeokuta provinces of Nigeria.

It is a small tree, scarcely exceeding 4 feet in girth. It has a large, oblong, dark leaf. It is most commonly seen in the middle of a compound with a pot at the base of it. The flowers are trumpet-shaped, white-coloured at the base and rose-red at the mouth. The fruit is a long, thin black pod, which opens releasing many flat, winged seeds. The seed is yellow and in the middle of the wing.

The timber is white and soft.

It has not been exported or cut for local use.

Native Use.—The tree is used to mark boundaries. It is a “Ju-ju” tree, both in and outside the compound. It is sometimes used for fences. It is used by the Yorubas for rafters.

Acanthaceæ.

Thunbergia Vogeliana (Benth.). Blue Benin Thunbergia. Ohwohiro (Benin).

This is a shrub with handsome blue flowers; it is moderately common in the Central Circle.

Rubiaceæ.

Sarcocephalus eu-esculentus. Sierra Leone Peach. Egbesi (Yoruba); Aragbaihi (Benin); Amellaky or Egbessye of Sierra Leone.

It is found in the Abeokuta, Ibadan, Benin, Onitsha, Owerri and Ogoja provinces of Nigeria, where it is common in the open deciduous forest.

In habit it usually takes more of the shape and form of a shrub rather than a tree, though where it is protected a longish main leader grows up, but even this droops. It rarely attains a height of more than 15 feet and a girth at the base of about 18 inches. The leaf is large and oval, opposite, and rather leathery to the touch. The fruit is not unlike a peach, except that its surface is not smooth, but is pitted in small depressions, giving it a more special peach colour. The flesh is very woody and tough, interspersed with small seeds not unlike those of the strawberry. When ripe the birds eat them. The roots are of a yellowish-brown, especially when the cortex is rubbed. The slash is yellow. The leaf is very shiny.

It does not really reach timber size, but the sapwood is a light yellow and the heartwood a darker yellow.

It is a moderately quick growing, light-demanding, soil-protecting and soil-improving tree. Natural regeneration is poor, but reproduction by root suckers and stool shoots is very strong. It is very fire-resisting, and recovers easily from any effects of fire.

Native Use.—In cases of scarcity of building-timber, occasionally short sections are obtained from it for hut-building. It is, however, usually too short. The roots are used medicinally in the following way: roots about a ¼ inch in diameter and upwards to ¾ inch are thoroughly washed in water and cut up into sections of about 4 inches long and boiled in water. The solution thus made is strained off, and is drunk either hot or cold in fairly large doses for the relief of venereal disease (G.) in its earlier stages. Most of the natives affirm that it gives great relief, though they acknowledge that it does not prove a cure for it.

Sarcocephalus esculentus. Weatherboard Wood. Opepe (Yoruba); Obiache (Benin); Awessu (Jekri).

It is found in the Abeokuta, Ondo, Benin and Calabar provinces of Nigeria, where in certain localities it is very prevalent.

It is a large tree of the evergreen forest zone, which attains a girth of 12 feet and a corresponding bole length. The bark is slightly rough and scaly, but in an even manner. It bears a large edible fruit 2 inches in diameter. The fruit is not unlike a peach in shape and colour, but with a rougher and softer skin. It is very closely and finely pitted with tiny holes in its surface. Inside, the flesh is pinkish-white. It is commonly seen at the edge of freshwater swamps in the Benin, Ifon and Ondo districts. It likes soil with good drainage, but it may be very moist.

The bole is very straight, and not unlike that of real African Oak in appearance. The leaves are rounded and moderately large, and inclined to be leathery in texture, with two stipules at the base. In the young seedlings the stem is more quadrangular in shape than round, and there are a few almost straighter furrows running vertically up it.

It tends to spread with the opening up of the evergreen forest. The root spurns are very slight and round, merging into the stem a foot or so above the ground. The slash is yellowish-white, and a rather dirty colour. Mucilage-like latex gradually exudes from the cut.

Timber.—The wood is very durable indeed, both for exposed places and for interior work. It is moderately hard, a little open and fibrous in grain, of a yellow to orange colour, with slight variations in its distribution through the wood. It planes well and saws easily; splits fairly well, takes nails, and does not warp or shrink very much. There is only a slight difference in colour between the sapwood and heartwood, but the sapwood is not quite so durable. It is termite-proof. It is usually very straight-grained, free of knots and other internal defects—in fact, it is one of the cleanest of all the African timbers.

It is a very fast-growing, at first slightly shade-bearing and later light-loving tree, which thoroughly protects and enriches the soil with its leaf fall. In fact, after the first two years it is very impatient of shade, and grows very slowly, if it is at all under large trees. In suitable places natural regeneration is very good. Fair crops of seeds are borne almost every year. In some places, notably north of the Ikoha in the Benin province, it is almost gregarious in habit. It sprouts well from the stump. Here again, unless there is sufficient light, it does not grow rapidly, and even tends to die down. In the nursery, seeds generate readily, but often fall a prey to the Duika, which eat the young seedlings. The tree does not stand transplanting very well, as it throws back its development very considerably. Small plantations have been made in one or two places. Close planting appears to be the correct method, as the branches are rather persistent and liable to form knots or places of decay in the stem, if they do not drop off when they are quite small.

In 1906 samples of this timber were sold as a hardwood in Liverpool market, where it was considered to show little or no merit. However, since that date there have been increased demands for all good timbers, so that it seems worthy of a further trial. Locally it has been used for making canoes, or has been cut up for planks. It has also been used for bridge-building and other constructional work, and being one of the most durable, ever wider use is being found for it, quite apart from any likely demands for export.

Native Use.—It is felled for sawing up into planks and making canoes, and is considered one of the best of all local timbers, except Iroko.

Sarcocephalus sambucinus (?). Yellow Wood. Opepe (Yoruba); Ebengiku, Obiache (Benin); Eben (Jekri).

It is found in the Ondo, Benin and Warri provinces of Nigeria.

It is a medium-sized tree of the swamps, both near rivers and near the sea coast—in fact, it will grow in waterlogged places—whereas the Sarcocephalus esculentus, to attain large dimensions, likes drained soil.

The fruit is only an inch in diameter, but of the same colour as the former. The pitting of the surface is more widely distributed and the pits are shallower. The bark is less scaly, with a very slight roughness or fissured surface. The wood is not so durable as the former, especially in exposed places. On the whole, the leaves are larger than S. esculentus and a little thinner.

The sapwood is whitish-yellow and the heartwood of a deep yellow colour. It is more fibrous and rather more open-grained than that of S. esculentus. The pores, too, are longer. On the whole, it is easier to work, a little softer, planes well, takes nails, splits well and saws easily. It is doubtful if it is termite-proof.

Although really a light-loving tree, it can stand more lateral shade than S. esculentus. It is a thoroughly soil-protecting and soil-improving tree, the foliage making a very rich humus. It is much more slow-growing than S. esculentus, though on the whole it will stand closer together, and yet grow well. It sprouts well from the stump. Natural regeneration appears to be good. It is sometimes almost gregarious in habit, and in some places one of the few valuable trees in the swamp region. It is also often one of the few of merchantable size. No plantations have been made with this tree.

In 1906 samples of this timber were sold in the Liverpool market as cedar, but it was only considered of poor quality. It deserves, however, further trial now. Locally it is occasionally sawn up for planks.

Native Use.—It is sometimes used for making canoes, but it is not liked by the natives, because they say it is not so durable as S. esculentus.

Sarcocephalus sp. Swamp Opepe. Oppepera (Yoruba); Eben Obiache (Benin). Perhaps the same as the foregoing species.

Morinda sp. Brimstone Wood.

Ekiti district, Ondo province.

Morinda lucida. Brimstone Wood. Oruwo (Yoruba); Obiache (Benin).

Found in the Yoruba and Benin country.

Morinda longiflora. Ekiti Morinda.

Found in the Ekiti district, Mamu Reserve.

Pausinystalia sp.

It is found in the Eastern Calabar province of Nigeria. It is a medium-sized tree found growing in old farms. It has globular-shaped flowers with yellowish-red anthers, making it very pretty and conspicuous. It has a hard, yellowish-white wood.

Saccoglottis Gabunensis. Mahogany, Tala. Ugu (Benin); Attalla (Jekri); Edat (Efik); Tala (Brass); Tala (New Calabar); Edat (Oban, Ekoi).

It is a large tree, attaining a girth of 15 feet and a height of 150 feet. Nearly always found on swampy ground, or anyhow where the rainfall is high, as, for instance, in the Oban district. One of the first trees to be seen in the forest immediately behind the mangrove swamps. The bark is roughly fissured like elm, but more regularly, and the slash is red. The fruit is an indehiscent nut with small nodules on it, about the size of a walnut, which exudes a liquid not unlike honey. Bees often frequent the tree for that reason. A reddish sap exudes when the tree is cut.

It is found in the Benin, Warri, Owerri and Calabar provinces of Nigeria.

The wood is hard and dark-red, with a fairly close grain, though easy to work. The sapwood is usually very narrow and yellowish-red.

It is evidently a shade-bearer, and stands a good deal of shade in its youth. Natural regeneration is fairly good where the rainfall is high. It seems a moderately fast grower, though no actual measurements have yet been taken. It is almost gregarious, especially in Oban. In 1906 it was valued in the Liverpool market at 3d. to 6d. a superficial foot as a mahogany of mild texture and fairly good colour. It has, however, not been used by the Public Works Department.

Native Use.—In the Benin, Warri and Calabar provinces the bark is stripped off in rolls about 3 feet long and sold for making gin bitter, by placing it in the liquid. A bundle of bark is sold for 5s. at Calabar. In the Degema and Brass districts it is one of the common canoe trees.

Mitragyne macrophyllum. False Opepe. Burokossa, Bulokossa, Ugbodokossa (Benin); Ebar (Brass); Ebar (New Calabar); Ubuen (Efik).

It is found in the Abeokuta, Ondo, Benin, Warri, Owerri and Calabar provinces of Nigeria.

It is a large tree, attaining a girth of over 12 feet and a height of over 100 feet. It has a very large leaf. The tree is often more or less gregarious, more especially in the moister or almost swampy parts of the evergreen forest zone. The bark is of a dull-green colour, comparatively thin, and only slightly fissured in a large tree.

The sapwood is yellowish-white and the heartwood of a pale yellow colour. It is almost a hardwood, does not split well, planes up smoothly and saws comparatively easily. It hardens considerably on seasoning and is very durable under cover, but not so much on exposure to the air. The dense foliage makes a thick layer of humus under the trees, as a few of the leaves fall off each year. It is thus a soil-improving and soil-protecting tree. It would probably be found to make a good mixture, in groups of about half an acre in extent, with mahogany in the evergreen forest zone. In the Brass district it is one of the commonest trees which is used for making canoes; it has also occasionally been sawn up for planks. It has not yet been exported to England, but at any rate locally it should command a wider use in house-building of all kinds.

Mitragyne Africanum. Akpakossa (Benin).

It is found in the Benin, Ondo, Warri and Calabar provinces of Nigeria.

It is a somewhat common tree on the borderland of the mixed deciduous forest and the dry-zone vegetation. The tree is of small size, attaining a girth of about 6 feet and a bole length of 25 feet; the leaf is very large, but does not reach the size of M. macrophyllum. It is most frequently found in the swampy places at the edge of the deciduous forest; like the sister tree, it is more or less gregarious, though the groups are usually not very large.

The timber is of a dull yellowish-white colour, and planes well; it does not split very easily and is very durable.

This species is a shade-bearing tree of soil-protecting and soil-improving qualities, owing to the dense bed of leaves, which in turn makes a bed of humus at the base of the tree, and thus grass-fires are very much hindered in spreading. The timber has not been exported to Europe and the natives scarcely ever use this wood.

Randia malleifera. Buje nla (Yoruba).

Found in the Olokemeji Reserve.

Randia octomera (Hook.). Buje (Yoruba); Assun (Benin).

It is found in the Benin province. It is a shrub with spherical-shaped fruit like an apple, with the sepals projecting from the top. The fruits yield a black dye which is used by the natives.

Randia cladantha (K. Sch.).

It is found in the Benin province of Nigeria. It is a woody shrub having a hard wood, and rather pretty red flowers in the autumn, which brighten the evergreen forest very much.

Randia maculata (Kew). Buje, Buji dudu (Yoruba).

A shrub having large, trumpet-shaped flowers. It is very ornamental.

Randia caudata. Blue Dye. Buje (Yoruba).

It is a small tree, 15 to 20 feet high. Found in the Olokemeji Reserve.

Mussænda Isertiana. Igi Ira (Lagos) (Benin).

Lagos.

Pavetta Baconia (Hiern). Idofun, Igbo (Yoruba); Akapano Iyokheze (Benin).

It is a common tree in the Calabar, Warri, Benin, Ondo and Abeokuta provinces of Nigeria. A small, shrub-like tree, reaching about 3 inches in diameter, most common as an undergrowth plant in the evergreen forest zone. Many specimens are found in the Obagie Forest Reserve. It stands the shade well, is moderately hard, and sprouts well from the stump. The natives of the Benin country cut young specimens very largely for use as yam-sticks.

Hymenodictyon bracteatum. Obadon (Benin).

Found in the Benin province of Nigeria.

Corynanthe paniculata (Welw.). Olikiba Anikiba (Benin).

So far it has been found in the Benin province of Nigeria, but either this species or Johimbe should be found in the Calabar and Ogoja provinces.

It is a medium-sized tree of the mixed forest zone, which is moderately prevalent in certain localities.

The timber is brown, hard and durable. It planes well and splits moderately well. It takes nails and saws moderately easily for hard wood. It is considered termite-proof by the natives.

It is a somewhat slow-growing tree, a shade-bearer, a soil-protecting and soil-improving tree. Natural regeneration only appears to be slight. It does not sprout very prolifically from the stump. No experimental plantations have yet been made.

This is a sister species to C. Johimbe, which yields the bark containing the very useful alkaloid Johimbin, but as yet the bark of this tree has not been tested for a similar substance.

In the timber report of 1906 it is valued at 2½d. to 3½d. a foot as a species of gummy mahogany, and in another case as fancy wood at 1d. per superficial foot or 1s. 6d. to 1s. 9d. a cubic foot.

Amongst the Benin natives it is used for wall-plates, for which purpose it is highly esteemed.

Crossopteryx Kotschyana. Ayeye (Yoruba).

A small tree found in the dry-zone forests, of no special value. The fruit is leathery; the flowers grow in panicles.

Native Use.—Parts of the tree are used in medicine by the natives.

Sabicea calycina (Benth.). Agan Aparo (Yoruba).

Found in Iro.

Canthium glabriflorum (Hiern). Attan (Benin).

It is a common tree in the Calabar, Ogoja, Warri, Benin and Ondo provinces of Nigeria, also in the Cameroons.

It is a medium-sized tree, reaching a girth of 9 feet, but with a bole length of about 60 feet, rather longer in proportion to the girth. The flat, wide crown is typical of this tree, as are also the large tripinnate leaves and the brown, stringy bark with slight fissures. The branches spread out almost in two or three whorls near the top of the tree. The light can be seen through the crown. The flower is white, in large, umbel-like masses of small flowers, borne on the upper side of the branches. It flowers in November.

The sapwood is white and fairly broad and the heartwood is brown, like cedar. Termites attack in the open.

It is a light-lover and grows quickly, in old farms especially. It sprouts well from the stump, but there are no root shoots. Seed production is good, and seedlings appear in near open spaces.

It has not been cut for local use or exported to Europe.

The branch is used. It has to be placed on a boy’s head and is said to make him grow. The boys do it themselves in the Benin country. The wood is also a firewood in Benin.

Compositæ.

Vernonia conferta. Big-leaf African Cabbage Tree. Onimagugun, Shapo (Yoruba); Orimagugu, Oriweni, Onamagungun (Benin).

It is found in the Abeokuta, Ibadan, Benin, Onitsha and Ogoja provinces of Nigeria, in clearings at the edge of the mixed deciduous and dry-zone forests. It is a very common small tree or large shrub, springing up in all old farms. The very large bright-green leaves, set opposite to each other on a small, comparatively, stout, green, succulent stem, are most typical of this plant. The fresh leaf, especially on the smaller plants, is not unlike a very open cabbage leaf, but of a lighter green hue. As the plant gets older the leaves do not attain such a size. The flowers are small, but grow on large, open and much-branched spikes. The stem is comparatively soft and pithy, scarcely forming a real woody tissue. When dried they can be used for firewood and kindle easily. Occasionally it is used for making live fences.

Vernonia Nigritana (O. and H.). Bitter Leaf. Ewuru or Oko (Yoruba); Ihagobo (Benin).

This is found in the upper part of the Benin province of Nigeria, near Sabongida, in the deciduous zone. A small shrub-like tree, the leaves of which are used for soup. The dried stem is used for kindling wood. The roots are sometimes used as chew-sticks.

Vernonia amygdalina. (Del.). The Bitter Leaf. Ewuru (Yoruba), Oriwu (Benin).

Yoruba Chew-stick, also known as the Chew-stick of Ewuro, thereby clearly showing the Yoruba origin of some of the inhabitants of Sierra Leone, as Ewuro is also the name of it in the Sierra Leone country.

It is found in the Abeokuta, Ibadan and Benin provinces, where it grows in openings in the mixed forests.

It is a small shrub, reaching a height of about 5 feet, having soft leaves, with rather a greyish tint, which are covered with very fine silvery hairs. It is commonly found in old farms and by the side of the roads, usually in small bushes or clumps.

It sprouts up when cut down, and thoroughly shades the ground. However, it is sometimes so thick that it rather hinders plantation operations, though once the other plants are established it acts as a useful little “nurse.” The leaves are picked off by the natives and cooked in water for making soup. They have a distinctly bitter flavour, but make a very healthy vegetable soup. The leaves are often sold in the local markets. This shrub is occasionally left more or less in line as a small living fence.

Vernonia cinerea (Les.). Ash-coloured Fleabane. Elegbe Oju (Yoruba).

It is found in the Olokemeji Reserve of the Abeokuta province of Nigeria. A large, woody shrub, one of the chewstick family, the leaves of which are sometimes used for making soup.

NOTES ON NIGERIAN TREES OF WHICH THE BOTANICAL NAMES ARE NOT KNOWN

Itufiak or Etufiak (Efik). Essunwoi (Yoruba); Ilako (Benin).

It is a medium-sized tree of the freshwater swamps, with heavy dark-green foliage; it grows quite gregariously in stands of one to ten acres in extent. The trunk reaches a girth of about 7 feet and a bole length of about 30 feet. The roots spurns are comparatively slight, and do not extend much over a foot up the bole. The foliage is very heavy and it casts a most dense shade, making patches of this forest the darkest of almost any in Africa.

It is common on the banks of the Itunkpe Creek, a tributary of the Kwa River, near Calabar, in the same named province, and also in the Owerri province of Nigeria. It belongs to the evergreen forest zone.

The timber is a reddish-brown hardwood of close grain, which would saw into sizeable planks. It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. The leaves yield a thick bed of humus. It appears to be one of the most valuable trees in this respect. It is moderately hard, with even, close-textured grain. It planes well, saws fairly easily, takes nails, but does not split well. Natural regeneration appears to be good. It also sprouts from the stump.

The timber has not been exported, nor has it been cut for planks for local use. It appears to deserve a trial as a local timber for floor-boards or for the making of boxes. Considering that so often many trees are found in the same place, it should not be difficult to obtain adequate supplies.

Native Use.—Building, but it is attacked by the insect called Efiak.

Musk Tree. Owi (Benin).

It is found in the Benin province of Nigeria, in the evergreen forests. It is a medium-sized tree, reaching a girth of about 8 feet with a short bole of about 10 feet. The crown is large but rather elongated, and reaches down two-thirds of the height of the tree. The fruit is large and more like an avocado pear in shape and colour. The leaf is very large and wide, more like a teak leaf, but of stronger texture, the midrib especially being very thick.

The timber is hard, with white sapwood and green heartwood. It splits well and takes nails fairly well. It is a little fibrous in texture, but can be planed; it saws fairly easily.

It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. The leaves make a rich humus. Natural regeneration is none too good. Stump sprouts do not appear to be very strong.

It has not been exported or cut for local use, but would be worth trying for house-building.

Native Use.—The fruit is kept for four days and then the inside large kernel is eaten. The young leaves are used for curing boils, as an external plaster to draw the poison.

Ekkiowa (Benin).

It is a small shrub which is found in the Benin district of the same named province. It is not very common.

Native Use.—The seed is used medicinally for the hands in case of sores which are red or raw.

Satinwood. Okwaba (Benin).

This tree is found in the mixed forests of the Benin province of Nigeria.

In 1906 sample logs of this timber were sold in the Liverpool market as satinwood, but were not considered worth shipping. Since then, however, none has been cut for export or for local use. Perhaps owing to the increased demands for all kinds of timber a further trial should be made with this one for satinwood. Natural regeneration is poor. It is a somewhat slow-growing, shade-bearing, soil-protecting and soil-improving tree. It reaches a large size.

Ubellu, genus? Annamamilla (Benin).

It is found in the Benin province, Nigeria.

It is a small tree, the name often confused with the mahogany-walnut, Lovoa Klaineana, which is also sometimes known as Annamamilla in the Benin country. The leaves are imparipinnate. It is a softwood with light-brown heartwood and little black, spherically-shaped fruit, unarmed.

Native Use.—Firewood of good quality. Not used otherwise.

Big Hardwood. Arugbo (Yoruba); Eto (Benin).

It is a very large tree with a wide crown. The timber is of a brown colour, but the sapwood is white. It is extremely hard and durable; even when felled in the farms it will be six years before it has rotted away. The bark is a dark-green with white lenticels scattered over it.

It is rather a rare tree in the Benin province of Nigeria. Standing a good deal of shade, it is a soil improver and protector. Natural regeneration does not appear to be very plentiful.

It does not sprout up when coppiced.

Native Use.—None.

Ifon (Yoruba). Owehe (Benin).

Is a small tree which has scented wood. It reaches a girth of 20 inches only. Before going to market, according to the natives, the feet, hands and body should be washed with a solution prepared from the bark of this tree mixed with soap. The object of this operation is to effect quick sales at the market.

Ewayron (Yoruba).

A leaf for wrapping up food, found in the Yoruba country, also used in Benin for roofing houses.

Mahogany. Alode (Benin).

This tree is found in the mixed deciduous forests of the Benin province of Nigeria.

In 1906 samples of this timber were sold in the Liverpool market as a species of mahogany of a soft nature. Since that date none has been felled. Perhaps with the changed conditions with regard to the demand for all timbers similar to mahogany a further trial with the timber of this tree should be made. Natural regeneration is not very good. It is a rather slow-growing, soil-protecting and soil-improving tree.

Spiny Tree. Oaha (Benin).

It is a small tree found in the Benin, Ondo and Abeokuta provinces of Nigeria. The small, rather thin and longish spines on the stem are the most typical feature of this tree. It usually grows with aerial roots. It reaches about 3 feet in girth, and on the whole is more common in the secondary forest than in the primeval. The wood is moderately durable, especially when used for inside work, such as verandah-posts.

Native Use.—It is sometimes used for small poles for hut-building.

House Post. Ewai (Benin).

A common tree in the Benin and Abeokuta provinces of Nigeria. It is a slow-growing tree which has a very hard brown wood; it is a shade-bearer. The seed is a small nut. The wood is used by the natives of Benin for building-posts, rafters and small planks.

It is found in the moist evergreen forest zone and is somewhat common in the Obagie Reserve of the Benin district.

Ussehin Chew-stick. Okuta (Yoruba); Okuta, Opahan (Benin).

It is rather a rare tree of the Benin, Ondo and Abeokuta provinces of Nigeria. The name means “a stone,” and has apparently been given because of the hardness of the wood. It is a medium-sized tree, reaching a girth of about 5 feet. The wood is almost white, and there is little difference between sapwood and heartwood. In the Ussehin country of Benin it is used as a chew-stick. The Yoruba states that it is the hardest of all native woods.

Akpo (Benin). Hardwood.

It is rather an uncommon tree of the Benin province of Nigeria, also a very hard wood, a medium-sized tree. The brown heartwood is used by the natives for planks. It is thought rather highly of by the Benin natives, especially for wall-plates and joists. In the past it has been only hewn by them, but not sawn.

Ukpaigwi, Okpaigwi (Benin).

Rather an uncommon tree of the Benin province of Nigeria. It grows to 10 feet in girth and yields a soft wood which is attacked by white ants. It is a shade-bearer and soil-protecting tree. The roots are used by the natives for medicinal purposes.

Oruru (Benin).

It is a tree found in the Benin province of Nigeria.

It is a small tree, reaching a girth of 2 feet. After three years it comes up in an old farm. The slash is red and a little red sap exudes slowly. It is usual to find thirty small ones in one place, from root suckers, but also from stool shoots if a tree has been cut down before. It is similar to Eranpata in this respect. The fruit is round and small and like peas, only a little larger. The flower, which is white and quite small, grows in small clusters.

The wood is not hard and white all through. It is attacked by termites, except when placed in the house, where it is more or less protected.

Reproduction by stool shoot is the best method.

It is a shade-bearer and grows slowly. It grows in good soil of some depth and also in the evergreen forests. When it appears in old farms, it stands the fires well.

It is a soil-improving and soil-protecting tree, and tends to spread with the extension of cultivation, especially in the evergreen and mixed deciduous forest zone.

As it does not reach timber size, it is not worth trying as a building timber.

The fruit is edible; after eating it the tongue becomes almost of a blue colour. The root is used medicinally. The branches are used as pegs in the top of the walls of the houses in Benin, partly for fixing the roof.

CHAPTER X

THE FORESTS AND TIMBER PRODUCTION OF THE BRITISH SPHERE OF THE CAMEROONS

Running parallel with the Nigerian boundary, a strip averaging 75 to 90 miles in width, and running back from the coast about 300 miles, we have the British sphere of the Cameroons, in all, an area of about 31,000 square miles. From the forest-zone point of view this land area can be divided into really three different zones. First of all, nearest the coast, there is Victoria, the Cameroon Mountains, followed by the bank of the Mungo. Past the crest of Kuppe and the Manengube Mountains and onwards along the Mbo, Foto and Bambuto Ranges round to the headquarters of the Cross River and to the Nigerian boundary, we have about 7,000 square miles of an almost unbroken evergreen forest zone.

The second area comprises a beautiful open grassland with only scattered trees, covering largely the Chang, Bamenda, Kontsha and more northern districts of the British sphere, in all about 17,000 square miles.

The third section comprises the heavy evergreen and deciduous forests on the banks of the more northern rivers, such as the Mo, the Cam, and covers approximately an area of 7,000 square miles.

From the forestry point of view, the most accessible, and therefore the most valuable, of these areas are situated in the first-named zone, therefore we will consider this area more in detail.

To begin with, it can be subdivided into three almost distinct forest divisions; following the watersheds or basins of (1) the Mungo River, (2) the Cross River, (3) the Akwayefe, Ndian, Moko, Meme Rivers and the Rio del Rey district. Taking the third area first, we have comparatively large areas of forest covering both level and hilly country up to an elevation of about 3,000 feet, but with the sides of the valleys less timbered than in the Mungo River forest zone. Amongst the species of trees which have been felled and exported from this area are the following: Mahogany Sarcocephalus, Bitter Bark, Saccoglottis Gabunensis, Light Mahogany, Khaya Euryphylla, Ebony, Diospyros Kamerunensis, Red Ironwood or Bongossi, Lophira procera, Long-capsuled Mahogany, Entandrophragma Rederi.

Amongst the more prevalent trees of the lower lying land, including the Tiko plain, are the following: Mahogany, Khaya Klainei, Long-capsuled Unscented Mahogany, Entandrophragma Candollei, Scented Mahogany, Entandrophragma utilis, Cedar, Guarea sp., Red Ironwood, Lophira procera, Canarium Schweinfurthii, Brown Ebony, Diospyros sp., Terminalia scutifera, Afzelia pachyloba, Berlinia sp., two kinds of Camwood, Walnut, Lovoa Klaineana, Pterocarpus tinctorius, as well as the valuable orange-coloured wood of Sarcocephalus sambucinus and Mahogany-like species of Guttiferæ and Uapaca Staudtii.

Some of the “stands” of this timber, and especially on the hill slopes of the Cameroon Mountains, are very thick and dense, more especially near Debundscha, with its annual rainfall of 423 inches.

One of the most interesting and unique stands on the mountainside is that of tree-fern, about 30 feet high, as an undergrowth, and heavy mahogany, Entandrophragma Rederi, and Ongekea Kamerunensis, chiefly at an altitude of 3,500 to 4,000 feet, also quite untouched except in the neighbourhood of Buea.

Only the smallest part of all this area, and in fact only that on the bank of the Meme, had been at all operated upon before the war, and the forests on the banks of the Akwayefe were quite untouched. All the higher slopes and the northern sides of the Cameroon Mountains, and beyond as far as Mount Gonistan, were also quite unused. All through this part the villages are comparatively few and far between, and even in those parts where they are closer together, the population in each is very small, and the forest growth is so thick that they make little impression upon it. Added to that, the chief crop grown by the natives is the cacao-yam, for which only comparatively small areas are necessary, and in many cases this is grown in small spaces in the shade of giant forest trees. Also, all through this area only comparatively small patches, compared to the whole, have been cleared and planted with cacao. Again, the area occupied by the European-owned cacao and rubber plantations is very small, and chiefly found near Victoria and a little both westward and eastward at the base of the Cameroon Mountain (Mount Fako).

Turning now to the Mungo River region, we have in some ways an even more valuable forest area. Here, indeed, one German firm had actually made a felling over an area of nearly one square mile and had sold nearly all the timber in Germany.

Amongst the more prevalent species found are the following: Bush Oak, Chlorophora excelsa, Black Ebony, Diospyros Gilgiana, Pearwood, Mimusops Djave (which is found in immense specimens on the edge of the Kumba road), Inoi Nut, Poga oleosa, with its light-reddish wood with wide medullary rays; African Greenheart, Cylicodiscus Gabunensis, a magnificent tree; Shinglewood, Scented Mahogany, Guarea glomerulata, Brown Teak, Brachystegia cynometroides, Long-capsuled Mahogany, Entandrophragma Candollei, the Oil Bean, Pentaclethra macrophylla, Red Ironwood, not quite so prevalent; Lophira procera, Paddle Wood, Uvaria Busgenii, Gum Copal, Pterogopodium sp., Wild Mango, Irvingia Barteri, Light African Greenheart, Piptadenia Africana, Camwood or Barwood, Pterocarpus santalinoides, Wood Oil Nut, Ricinodendron Africanum, Hard Yellow Wood, Coula edulis, and Ironwood, Bridelia stenocarpa. Although the Bakundu and Balong natives are more active in their farming operations near the banks of the Mungo, there are still very large areas of comparatively untouched forests, and more especially in the upper regions of the river. In four separate places beyond the crossing of the Bakossi Road there are four different rapids or waterfalls on the river, which would provide water-power for saw-mills, or other wood-using industries. On the left bank of the river, beyond the Bakossi crossing, there is an area almost without population in which there are large numbers of Oil Palms, as well as other forest trees. On this road, too, is seen the very picturesque waterfall and narrow gorge of a tributary of the Mungo, which is also suitable for generating power for one kind of mill or another.

Turning now to the Bakossi forests, which culminate in the more or less isolated peak of Mount Kuppe (altitude 6,300 feet), the land is all covered with forest with the exception of some rocky points on the eastern side. A small amount of land has been cleared at an altitude of about 3,000 feet, for the making of tobacco plantations, but the rest, with the exception of the taking of a few trees for local felling, remains intact. The Bakossis have made large farms in the valleys, and are very industrious, but still the forests situated higher up are largely untouched. It is interesting to notice that the walls of the round and conically roofed houses are made with about five circular rows of tree-fern stems, cut to the length of the height of the wall and placed one behind the other. These are most durable and are a most unique example of the utilization of the produce of these forests, although many of the tree-fern “stands” have been cut down and have quite disappeared; a few remain in isolated places.

Some of the more common species found in this forest are the following: Bush Maple, Triplochiton scleroxylon, Ebony, Diospyros, Mahogany, Khaya Euryphylla, Bush Teak, Chlorophora excelsa, Gum Copal (Copaifera Demeusii), Bilinga (Afzelia Zenkeri), Hardwood (Millettia sp.), Scented Mahogany (Entandrophragma Candollei), Light Mahogany (Canarium Schweinfurthii), Hardwood (Dialium Staudtii and Newtonia Zenkeri), Yellow Hardwood (Ongokea Kamerunensis), African Whitewood (Enantia chlorantha), Camwood (Pterocarpus Soyauxii).

There is less forest near the Manenguba Mountains, most of it being situated on the banks of the Mo and Mbu Rivers (tributaries of the Cross River). Continuing along the boundary line between the grass country and the tree-fern forest, we have the Mbo and Foto Ranges, with their dense evergreen forests up to an altitude of 5,000 feet. Amongst the more valuable trees are the Cola (Cola laterita), Camwood (Pterocarpus Soyauxii), Albizzia species, Ibadan, Ficus Vogelii. Below this point, at about 4,000 feet, Iroko, Chlorophora excelsa, Corkwood, Musanga Smithii, and tree-ferns reappear, as well as Acacia Farnesiana. The Wild Date, Phœnix sp., occurs again about this altitude. The Oil Palm occurs again in the valleys. On the lower slopes there are Ricinodendron, Bombax, Sarcocephalus, and Trema.

Continuing farther northwards we have the Bambuto Ranges, with their fringing forests on the banks of the streams, and the bamboo groves at an elevation of about 8,000 feet. Willows and small Abyssinian plants are found, and with the flowering of Delphiniums in the grass we might almost be in Europe. Toward the Cross River side, the mountains are very steep, and isolated peaks, such as that of Monkwa Rock, stand out in solitary grandeur amongst the lower forested mountains of the Cross River. In the Cross River basin we have mainly six large rivers, all joining the Cross River. On the right or northern bank these are the Manyu, Mo, Manya, and Oyi, above Mamfe, and on the left or southern bank the Mbu and Manja, as well as the Awa, joining below Mamfe. All except one of these rise amongst the forests, and it is on the banks of these that the finest forests are situated, although in some parts, such as near Tinto, the natives have been more active in farming and have cleared large areas of them. This is more the case nearer the villages, and nearer the roads, even where the forest has been cut down, there are almost continuous groves of Oil Palms, less than a quarter of its produce having as yet been collected or sold. Amongst the most valuable timber trees of these forests are the Ebony (Diospyros), Bush Teak (Chlorophora excelsa), African Whitewood (Enantia chlorantha), Camwood (Pterocarpus Soyauxia), Bilinga (Afzelia Africana), Hardwood (Millettia sp.), Sapeli Mahogany (Entandrophragma Candollei), Light Mahogany (Canarium Mansfeldii), Hardwood (Newtonia Zenkeri), Wild Mango (Irvingia Barteri), Mukonja (Terminalia superba combretaceæ), White Cedar (Pycnanthus Kombo), Red Oak (Berlinia acuminata), Berlinia species with very large pod, three species of Walnut, Albizzias, Red Ironwood (Lophira procera), African Wood Oil Nut Tree (Ricinodendron Africana), Parinarium sp. (Dialium).

The range of hills Nda Ali is also forest-covered and is situated in the Cross River basin.

More or less adjacent to these areas, and partly between these and the Meme River forest, are those of Gonistan and the Rumpi Mountains. These again are quite untouched, although, lying some distance away from navigable rivers, they may subsequently prove of greater value when eventually opened up with the forest tramway or other means of transport. The species of trees found here are very similar to those found in other parts. On the whole, Red Ironwood (Lophira procera) is most prevalent in Ogu and Mbu, as also both Mahoganies, Camwood (Pterocarpus sp.), African Greenheart (Piptadenia Africana), Corkwood (Musanga Smithii), False Iroko (Chlorophora excelsa), Hog Plum (Spondias lutea), Wild Mango (Irvingia Gabonensis), Hard Mahogany (Detarium Guineense). Numerous small Oil Palms occur in places. On the banks of the Fi, Cedar (Carapa procera), Hard Mahogany, Trichilia, an anacardiaceous tree; the hard whitewood Akboro (Benin), the brown hardwood, Microdesmis, African Greenheart (Piptadenia Africana), Heritiera sp., Scented Mahogany, Guarea Thompsonii, Chrysophyllum Africanum, and a very hard wood known as Alikongeba by the Yorubas are found. Near the Rumpi Mountains the following are more prevalent; the Sarcocephalus sp., Berlinia, Piptadenia Africana, Cylicodiscus Gabonensis, Oroko, Lophira procera, Satinwood, Zanthoxylum macrophyllum, Pattern-wood, Alstonia Congensis, Shingle-wood, Terminalia scutifera, Pear-wood, Mimusops Djave, Corkwood, Musanga Smithii, Scented Mahogany, Guarea sp., White Cedar, Pycnanthus Kombo, Camwood, Pterocarpus sp., brown hardwood, Microdesmis, Wild Mango (Irvingia Gabunensis), Gaboon Mahogany, Canarium Schweinfurthii, Bilinga (Afzelia pachyloba), and Walnut.

Out of the total of 14,000 square miles of forest, 6,000 must be deducted as being inaccessible for many years to come. Again, out of this 8,000 square miles, 4,500 square miles will be made accessible as soon as those areas lying nearest the rivers have been opened up for timber extraction. Therefore only these last areas will be taken into consideration at the present time.

The chief timber forests comprised in this area are those situated between the Mfu and Fi, the Fi and Mbu, and the Manja and Mak Rivers.

On the whole, in the Cross River basin there is an area of fully 2,000 square miles of exploitable forests, within reach of streams or rivers deep enough to float logs in the rainy season. In the Akwayefe, Ndian, Moko, and Meme River valleys there is another 700 square miles. Again, on the banks of the Mungo and its tributaries there is an area of about 800 square miles suitable for the extraction of timber. In all, then, there is an area of 3,500 square miles of forest which could be utilized at the present time. Assuming that only one tree on every four acres is of value for export, and that each tree is worth a nominal amount of £1, therefore the whole forest is worth £575,000. In addition to these there are many other trees which would become valuable either for export or for local use as soon as the forests were opened up and utilized, and this would at least double the value of the forest. This, also, is one of the last remaining large tracts of forest where the population is smaller and the requirements for forest products less than those to be had in the forest. There is thus a surplus for export. Up to the outbreak of war, out of all this area only 47,000 acres, or 73½ square miles, had been, or was being, leased as timber areas. Outside these areas some 285,000 acres, or 445 square miles, had been alienated, chiefly on the lower slopes of the Cameroon Mountains and in the neighbourhood of Mount Kupe. Under the old German law, ten marks per ton was charged on Ebony, Mahogany, Bush Oak, and one or two other species, and five marks on all soft woods, except certain trees which had proved unprofitable to export. Compared with those in force in Nigeria, these fees were very low, and despite the fact that on the average the Cameroon forest would be more difficult to exploit than the average one in Nigeria, there should still be more profit in the former; also, with the considerable number of water-power sites available, timber conversion could be undertaken, and thus the cost of transport cheapened in comparison with the value of the product to be transported. Well-squared logs, large flitches or planks of timber could be cut and transported. Under the German Colonial land law, with the exception of 15 acres per head allowed to each native, all the land could be declared Crown land, so that no difficulty would be involved in leasing land to timber companies; that is to say, it was first declared to be Crown land and then subsequently leased to timber companies. The natives, however, then received no royalties on the trees which were felled. Thus those in the immediate neighbourhood had no incentive to work in the forests as they do in Nigeria. Sufficient emphasis was not laid on the fact that a timber company should possess ample capital.

In afforestation a great deal had been planned, but only a small amount had been executed. In the north, at Fontwans, in the Dschang district, a 40-acre teak plantation had been made. At each of the stations themselves, Dschang, Mbo, Djutisha, various experimental plots of trees had been planted. Nearer the coast, at Kumba, valuable test plantations, aggregating some 400 acres, had been planted with Ebony, Diospyros suaveolens, Umbrella Tree, Musanga Smithii, Casuarina, Casuarina equisitifolia, Cigar-box Cedar, Cedrela, Iroko (Chlorophora excelsa), Djave Nut (Mimusops Djave), Teak (Tectona grandis), Para Rubber (Hevea Braziliensis), Cacao (Theobroma cacao), and Oil Palms (Elæis Guineensis), Red Ironwood (Lophira procera), Mahogany (Khaya euryphylla), and Heavy Mahogany (Entandrophragma sp.).

At Mussake at an elevation of 6,000 feet on the side of the Cameroon Mountains, there was a quinine plantation. At an elevation of 3,000 feet at Buea there were small experimental plantations of tea, Ceylon and ordinary, quinine and Casuarina. Several of the roads had been planted with avenues of cypress and Biota trees. On the coast at Victoria, small Casuarina plantations had been made. For the furtherance of all agricultural and forestal interests, the very extensive Botanical Gardens had been made. Not only is it the largest, but it contains the most extensive collections of plants of economic value and for ornament of any place on the West Coast of Africa. The very numerous test plots of most of the tropical commercially known plants, such as Nutmeg, Rubber, Cocoa, Cola, Cocoanut Palms, Oil Palms, Vegetable Ivory Palms, demonstrated how these grew in the Cameroons.

Then the agricultural areas of Cacao-yams, Casada, Sugar-cane, Rice, one and all were destined to demonstrate the value and possibilities of growing these products in the Cameroons. Then again the forest tree plots of Teak, Casuarina, Mahogany (Swietenia macrophylla), Trinkomalee Wood (Berrya ammomilla), Gum Copal (Copaifera Demeusii), Candle Nut (Aleurites Moluccana), Balsam of Peru (Toluifera Pereiræ), Terminalia sp., Dillenia Indica, show how these trees will thrive in this locality. In growth, an avenue of Indian Almond, Terminalia Catappa, could not be compared with those at Lome.

Again, all showed what forest products and forest trees were most suitable to that climate.

In the garden Museum, there were collections of timbers, fibres, rubber, gums, resins, as well as mineral products; also very full collections of the seeds, nuts and fruits of the trees and plants. Finally, there was the large and well-equipped building of the Experimental and Agronomical Institute, where chemical analyses of the soil and other processes could be undertaken and tested. Here also all the very full meteorological results were tabulated, as well as other observations on the spot. This served also as a centre to which planters or Government officers could send specimens or material to be named or to be examined as to their value. Allied with this, but having a separate building, was the Agricultural School, where pupils were trained in the elements of agriculture and forestry, so that they might subsequently act as instructors at the different Government stations and also serve as assistants on the plantations.

Although economically much more backward than Nigeria, and with a smaller population in a proportionate area than that in the Southern Provinces, the possibilities in the development of the forest products are even greater, especially in regard to that of palm kernels and all the various kinds of timber for which West Africa is gradually becoming well known. The main difference in working would appear to be that owing to the lack of population, much greater use of animal and mechanical means of transport, and especially mechanical appliances, as well as machinery, are necessary to make the labour most productive, as well as to economize without upsetting the present agricultural system and the very necessary production of food-stuffs for the local population, as well as for sending to the larger towns.

THE CONGO FRANÇAISE, OR THE FRENCH GABOON

To English-speaking mahogany producers and users the latter name conveys more, and reminds them of one of the chief products, Gaboon Mahogany, Oukoumea Klaineana, which had but a poor name in the London market. This rich French colony, however, should mean a great deal more to us with its huge extent, upwards of 300,000 square miles, and its comparatively large open waterways all flowing into the giant Congo. Its comparatively thin population per unit of area, and its almost impenetrable forests make it one of the largest of the last remaining primeval forests of Africa. Already before the war it was the largest timber exporting country of the West Coast of Africa. However, its somewhat ill-regulated timber trade had one or two drawbacks and laboured under several disadvantages. Most of the timber was shipped in the round—i.e. round logs. This means, of course, that in stowing these logs in the ship space is lost between them, and that space is charged for by the shipping company, despite the fact that it is often filled with “dunnage” in the shape of Ebony billets or even Camwood. In the round log, too, there is all the sapwood, and for this the merchant does not expect to pay much, if anything, and there is no doubt that it tends to depress the value of the timber, whatever it may be. The mere fact that the log is in the round is sufficient. Quite apart from that factor, too, a round log, even when it is a beautiful bit of redwood, never looks so well nor so workmanlike as a hewn squared log with clean-cut sawn ends. The sapwood, being softer than the heartwood, is more easily damaged than the heartwood in the squared log, so this is an additional reason why the round log often does not look as well as a squared one.

Amongst the most important timbers exported from the French Gaboon which are known and have been found suitable to the English market are the following:

1. Okoume or Angouma. Gaboon Mahogany. Oukoumea Klaineana.

2. Zaminguila or Ombega. Mahogany. Canarium?.

3. Duika. Mahogany. Irvingia Barteri?.

4. Kambala. Oak. Chlorophora excelsa.

5. Mandji or Bilinga. Afzelia Africana, or sometimes said to be Sarcocephalus Pobeguinii.

The first named has always sold at a cheaper rate in the London market than the timber obtained from the other genii of West African Mahogany, such as Khaya, Entandrophragma, Pseudocedrela and Lovoa. First of all, as with other timbers, the Gaboon Mahogany is shipped in round logs, which are cut none too straight at the ends, owing to the rough usage they get in the long transport by water; before and when reaching the port of shipment they are often much damaged externally, which gives them a bad appearance. The wood is not only lighter in weight but also lighter in colour than the other West African Mahoganies, and both these qualities detract from its value. The grain is more open; it rarely if ever shows any figure, in comparison to the highly figured logs from Benin and Bassam. Having been tested very thoroughly as to tensile, torsion and compression strengths since the beginning of the war, it has not proved to be nearly as strong as the other West African Mahogany. These tests having been conducted with scientific accuracy and impartiality, they are to be trusted. Thus, for some purposes, such as aeroplane propellor construction, Gaboon Mahogany has proved unsuitable. However, it is only the very best, very strongest and most durable kinds of mahogany that will stand the most severe strains, such as wood is subject to when used in this work. However, that does not preclude the wood from being used for similar purposes as the other kinds of West African Mahogany, where the strains and stresses are not so great and where the lighter colour is no advantage. In fact, in many positions a greater lightness in the weight of the wood would be a distinct advantage, which should be pressed for all it is worth.

Zaminguila is becoming better known, though previous to the war it could not be said that it had an established place in the market.

Duika Mahogany is scarcely known, and may be the wood of Irvingia Barteri.

Kambala or Oak, which is also known as African Teak, is much better known now, and in fact there is a steady demand for it, chiefly under the Nigerian name Iroko, which has been exported from Benin and Lagos in Nigeria in the form of “squared” logs.

Thus far very few forest regulations have been issued in the Congo Française and very little replanting has been done. However, for the present, the supplies appear to be very large, but they will no doubt get more costly as the timber has to be cut and obtained from the much more distant and inaccessible forests. Apparently there is little or no Khaya Mahogany in those regions, so that there is little fear of real competition between the main species of Mahogany found in the different West African countries. The natives work the timber chiefly, cutting and bringing it to the ports themselves.

THE BELGIAN CONGO

This, the greatest and largest river system in Africa, gives its name also to the largest compact forest area of that country. Of the 800,000 square miles, probably 700,000 are covered with forests of one type or another. From the mangrove swamps on the islands at the mouth of the Congo, through the dense evergreen forests of the Upper Congo to the dry-zone open deciduous or almost treeless areas of Katanga, an almost illimitable amount of unused sylvan wealth is to be found. Despite the obvious advantage of the Congo River, with its 3,000 miles suitable for timber transport and its hundreds of tributaries with many more thousand miles of streams, capable of floating logs, only the smallest quantities of mahogany are exported from the Belgian Congo.

No doubt the large size of the river and the great distance of some of the forests from the sea have hindered a more rapid and intensive exploitation of the forests. In fact, Mahogany (Khaya sp.) as an export timber is not really so well known as Redwood (Pterocarpus sp.), though the former has been shipped in the round. In the past a better known Belgian wood was blockwood or boxwood, known as Polyadoa umbellata or Dialium Guineense. Other forest products, however, such as Gum Copal (Daniellia sp.), are found in huge quantities, in large blocks weighing over a hundredweight, and have been exported for many years.

Large quantities of rubber, too, have been exported, and Oil Palm products, such as kernels and oil, are of increasing export importance, especially since Les Huileries de Congo have started working up the Oil Palm forests with modern means of transport and machinery on three different tracts of 10,000 hectares each.

The railways of the Congo, supplementing as they do the waterways, have also not been used to any extent for the shipment of timber, though vast quantities of firewood have been burnt on them as well as conveyed to the various stations both near and on the River Congo. To some extent the paucity and low density of population per unit of area has tended to hinder the working of heavy produce such as timber, which is difficult to transport compared to rubber, with its higher value per unit of weight. Owing to this fact, too, near the mouth of the Congo there is an almost savannah forest on the banks of the river, which has given the country the appearance of not being an afforested one. In the past the system of huge, exclusive trading concessions over specific areas being granted only to one firm also hindered any free development of the more lower-priced forest produce such as timber.

SPANISH GUINEA

From Eloby, a little-known port situated in the middle of the coast of the Spanish possession south of the Cameroons, a great deal of Gaboon Mahogany (Oukoumea Klaineana), Redwood (Pterocarpus Soyauxia), and several other timbers have been exported. Despite the fact that the forests are not extensive, but almost untouched, and very rich in mahogany, a comparatively small number of firms have been working these areas. Apparently there are no forest laws, and there is little or no security for any forest rights one may acquire from the natives. It would be perhaps advisable to work areas here in conjunction with those in the Southern Cameroons. It is supposed to be more unhealthy in this part than in others, though probably this is due to the local conditions. Khaya is less common than elsewhere, while Redwood (Pterocarpus Soyauxii), Gaboon Mahogany (Oukoumea Klaineana) and Bilinga (Afzelia sp.) are common woods.

CHAPTER XI

THE OIL BEANS, SEEDS AND NUTS OF THE FOREST

In a separate chapter the Oil Palm and its produce are more fully considered, so that we give here a detailed account of the other important Oil Seeds and Nuts. Oil-bearing nuts and seeds are usually found in great profusion in the Tropics, and West Africa is no exception to the rule.

Amongst the botanical families in which the plants yield oil-seeds or nuts are the Palmæ, Leguminosæ, Euphorbiaceæ, Ochnaceæ, Sapotaceæ, Rhizophoraceæ, Meliaceæ and Guttiferæ. As far as the Protectorates of Nigeria and Sierra Leone are concerned, the “Oil Bean” (Pentaclethra macrophylla) is one of the most important. According to the data in the Niger district, oil beans have been bought for some ten years from the natives. They are also known as Owala beans. The natives prefer a price of 1s. per case, but the minimum of 6d. and the maximum of 9d. per case was about the limit for the nuts in pre-war days. Even then only a small profit was made by the European merchant at the prices then ruling for the nuts in England. With the much greater, almost universal demand for all kinds of oil-nuts and seeds, it is probable that higher prices will be paid for these nuts now that the war is over, provided a reasonable charge for freight can be arranged. The natives themselves say that the nuts should be cooked for twelve hours to be good for eating. There are six or seven beans in each pod.

Now that many roadsides in the Owerri province and other districts have been planted with Oil-bean trees as a shade tree, there will be a continual supply of nuts each year. The tree starts bearing in the tenth year, and almost every year bears a fair crop. An example of one of these avenues is seen on the Ikpoba Road, just outside Benin City. The pods are used as a firewood, which makes a hot, rapid fire. In Sierra Leone they are known as Fai beans. The beans are large and flattened, covered with a hard brown seed-coat. They may be from one and a half to two and three-quarter inches in length, and from one to one and three-quarter inches in breadth, and one-third to nearly half an inch in thickness. The kernels are white and soft and contain a quantity of oil.

According to the very valuable investigations of the Imperial Institute:

- The proportion of hard seed-coat (by weight), 20·7 per cent.

- The proportion of kernel in bean (by weight), 79·3 per cent.

- The amount of oil contained in the whole, 31·2 per cent.

- The amount of oil contained in the kernels, 39 per cent.

When the oil is left to stand it deposits a quantity of solid fat. On trial, the oil was found to yield rather a soft soap, and was stated to be worth only about £21 per ton. The cold-pressed oil was of a golden yellow colour, and the hot-drawn oil a dull yellow and rather thick. From analysis it was found that the meal was very nutritious, containing over 39 per cent. of proteids, and if it could be used as a feeding-cake it would be worth from £5 to £5 10s. per ton (pre-war rates).

The constants of the oil from the Southern Nigerian seeds are:

Iodine value | 87·07
Acid value | 14·3
Titer test | 50·15° C.

The composition of the meal after extraction of the oil is as follows:

| Per cent.
Moisture | 12·9
Ash | 03·5
Proteins | 34·8
Fibre | 06·8
Sugar (dextrose) | 06·2
Carbohydrates (other than sugar) | 33·7

The oil on analysis gave the following results:

Specific gravity at 15·5° C. (60° F.) | 000·9194
Saponification value | 184·2
Free fatty acids, per cent. | 000·7

Analysis of pressed cake:

| Per cent.
Oil | 12·0
Moisture | 09·9
Crude proteins | 33·2
Carbohydrates | 34·8
Fibre | 05·7
Ash | 04·5

The oil would make a first-class edible oil. The value of the beans is stated to be about £6 per ton c.i.f. London, August 1909, and subject to being shipped in lots of fifty to one hundred tons at a time. No regular plantations have been made with this tree, but it is probable that with cultivation an earlier and quicker yield of nuts could be obtained, also with further grafting and seed selecting the thickness of the shell over the kernel could be considerably reduced, and also the thickness of the pod, and thus make the product more valuable in proportion to its size. A small tree will bear half to one bushel of beans, and a large tree will bear two. On the smaller and younger trees the pods are narrower and shorter than on the older trees, and the beans are much smaller, being only about half the size and a third of the bulk of those from fully-grown trees. The pods, which also contain a certain amount of oil, are not to be despised as a source of fuel, especially as time goes on and the population increases.

In this place also should be considered the beans of Xylia Evansii. This is also a Leguminous tree. The natives apparently have no use for the small, flattened round beans, which are about half to three-quarters of an inch in diameter and an eighth of an inch thick, and sometimes less. The beans have not been collected or sold, neither have they been examined chemically as to their oil or other content.

Another oil-bean-bearing tree of this family is Berlinia acuminata, which has large beans rather more than an inch and a half long, an inch broad, and a third of an inch thick. Further examination would show whether the oil content is such as to justify their commercial exploitation. The Benin name is Ekpagoi and Yoruba Apado.

Closely allied to this one is Macrolobium palisoti, the Ogaba of the Benis, which also yields a flat, almost square-shaped bean, nearly an inch in length and an inch in width. The exact oil content of this bean is unknown.

The beans of Cynometra Afzelii and Cynometra Mannii are much larger and stouter, but also contain a certain amount of oil of unknown value. The Benin name is Upakeka and Yoruba Eggi or Ekku.

Then we have the small, almost black, button-like beans of Brachystegia spicæformis, which, despite their large quantity, have remained uncollected and unused. A proper chemical examination would reveal the oil or other content of the beans. The Benin name is Okwan and the Yoruba Ako.

Still considering this same family of plants, the Leguminoseæ, there are the brown beans of Erythrophlœum Guineense and E. micranthum. These are of a brown colour, about half an inch long, one-third of an inch wide, and an eighth of an inch thick, and of a more or less round shape. Here, again, further investigation would reveal the oil content of these beans. The Yoruba name is Oginni or Inyi and Yoruba Erunor Obo.

It is also not known whether the nuts of the various Afzelias, known as Apa by the Yorubas and Aligna by the Benis, contain a valuable oil or other commercial product.

It has been stated that the beans and pods of Pithecolobium altissimum have been used as a kind of “Dividivi” for tanning leather, but further experiment with these would prove or disprove the point.

Finally, there is the Calabar bean or Eseri bean, Physostigma venenosum. It is known to the Efiks as Eseri. The deep furrow on the upper side of the bean is most typical of it, and differentiates it thus from the various Mucuna species. It contains two alkaloids, Calabarine and Eserine. These beans are comparatively well known. Besides being used locally as a medicine and for witchcraft, they are collected and sold for export. The bean used in games, Mucuna urens, has yet to be examined as to its value.

Amongst the other important families containing nut-bearing trees are the Rhizophoraceæ. The Inoy nut, Poga oleosa, is obtained from a common tree in the Owerri and Calabar provinces of Nigeria. The local people of the Oban and Calabar districts are very fond of the nut, and leave the tree standing when making their farms. The nuts sell in the Calabar market at the rate of 250 for 3d. They were examined in England and favourably reported on by the Imperial Institute in June 1905. The hard shell is against their general use, as it is so particularly tough and hard to crack. The shell on the nut itself is about one-fifteenth of an inch thick. The kernel is soft, white, and very oily. It has a better flavour than even the Brazil nut, and is pale-yellow in colour. The kernels were valued in May 1906 at from £9 to £10 in England. They contain about 60·8 per cent. of oil, which showed the following constants according to the investigations of the Imperial Institute:

“Inoy” kernels would yield a nutritious cake for feeding cattle.

Thus far no use has been found for the round small, pear-shaped, nut-like fruits of the Red Mangrove, Rhizophora racemosa. Considering the large quantity found floating about in the creeks and rivers, further investigation seems warranted.

In the Euphorbiaceæ family the Nsa-sana (Efik) or Okkwen nuts of the Benis have been found to contain 45·2 per cent. of oil by the Imperial Institute.[17] This nut is obtained from Ricinodendron Africana and R. Rautenii, and is known to the Yorubas as Erimado. In each fruit there are two, three, or even four nuts. The flesh of the fruit soon dries or rots away, leaving the uncracked nuts among the debris. The shell of these is hard and thick, and the inside a bright white colour. In some experiments carried out on a comparatively large scale at the end of 1907 and at the beginning of 1908, in Benin, it was found that more than half the kernels were broken in the cracking of the nut. However, in the Cameroons, where the nuts are used for alimentary purposes, they are boiled for a short time, and then it is possible to crack them quite easily without damaging the kernel inside. Further experiments at Benin showed that six boxes (gin cases) of green fruit yield one box of nuts containing actually 7,528, which weigh 35 lb. 4 oz. One box of fruit contains 418 seeds and yields 720 nuts. An average of 7,419 seeds is contained in each box, 155 nuts weighing 1 lb. Each fruit contains on the average two and one-ninth seeds. On the average 9d. per box was paid for fruit, and 1s. per box for uncracked nuts. Twenty boys cleaned and got ready 2½ boxes of uncracked nuts per day at the cost of 5s. Paying at the rate of 1s. a case for the uncracked nuts, the cost would be £17 per ton. However, with regular quantities being brought in, no doubt this cost could be reduced. In a similar way, if the nuts were boiled in quantity and immediately cracked, the kernels would be got out at a cheaper rate. The native working for himself, as with the palm nuts, would turn out greater quantities in a shorter time.

The yield of the oil pressed from the kernels was 47 per cent., or 14 per cent. on the whole nut. It is light yellow in colour and has a pleasant taste, very much like that of the ground nut. The chemical examination showed a resemblance to Tsung oil (Chinese wood oil). It possesses the same property of drying on exposure to air under ordinary atmospheric pressure. The oil could be used for similar purposes, or for the making of soft soap, and would be worth from about £18 to £20 per ton for this purpose, and it appears that the oil would have a ready sale in England, and have a value, equal to linseed oil, of about £21 per ton. According to the investigations at the Imperial Institute, the analysis of Nsa-sana kernels and Tsung oil showed:

Despite the large quantities of nuts available, especially in the Abeokuta, Benin and Calabar provinces, the difficulty of cracking the nuts satisfactorily and buying them cheap enough has so far precluded an export trade from being built up. Owing to the low percentage of oil in the whole nut it is evident that it would not pay to ship the uncracked nuts. So far no plantations have been made with this tree, but it comes up very readily and plentifully in old abandoned farms of the mixed forest zone. In open localities, with plenty of light, the tree begins to bear between the seventh and tenth year, and almost each year there is a large crop of fruit. From larger trees the yield appears to be over one bushel of nuts per tree per annum.

The curious nut-like fruits of Ubellu, Benin, supposed to be a species of Microdesmis, have not been examined as to their oil or other content. Soon after falling to the ground they break up into a white putty-like substance, which has a very peculiar, almost sulphurous, smell, and sometimes rather phosphoric. The nuts are spherical and rather more than half an inch in diameter. The tree is found chiefly in Benin, also in the Abeokuta and Calabar provinces.

Among the Euphorbiaceæ is the creeper, Manniphyton sp., known as Okwe to the Benis. The spherically shaped fruit with four raised ribs on its surface is cut open and contains one large round nut. It is about one inch in diameter. This is boiled for a few hours and is then edible, after the thin dark-brown husk has been removed. It can be peeled off with the fingers. The nut has a pleasant mealy taste and is very satisfying. Further examination would show whether it contains a valuable oil, and in what quantity. So far it has not been cultivated.

Of the Cucurbitaceæ, the seeds of Citrullus vulgaris, known as Ikpan by the Efiks or Egusi bara by the Yorubas, have been examined at the Imperial Institute[18] and found to contain from 40 to 41 per cent. of a pale-yellow oil. It is a common plant in the more open farms of the forest and does not demand a very high rainfall—45 inches. The natives use the kernels, after they have removed the hard skin, for making soup. It makes an excellent dish with rather a sweet taste. According to the investigations of the Imperial Institute[19] an analysis of the oil gave the following results:

Specific gravity at 15° C. | 000·9184

Saponification value | 194·0000
Iodine value | 106·0000
Hehner value | 095·5000
Titer test | 036·0° C.

The oil could be used for soap-making, and was valued at £29 per ton.

In the family Moringeæ there is Moringa pterygosperma, the Ben oil-seed tree. It is a common tree of the upper part of the Oyo, Benin and Ogoja provinces of Nigeria. It is also found in Borgu and other of the Northern Provinces. On examination by the Imperial Institute the kernels were found to contain 38 per cent. of oil, pale-yellow in colour and of a pleasant taste. The kernel is difficult to extract. At the Imperial Institute[19] the analysis showed:

From the Simarubeæ there is Balanites Ægyptica, Betu oil-tree of the Northern Provinces of Nigeria. Although it yields 58·7 per cent. of oil, the exploitation of it is almost impossible, owing to the difficulties in removing the husk, the external sugary pulp, and then the thick fibrous shell under the pulp. At the Imperial Institute,[20] Betu oil on analysis showed:

The family of Simarubeæ also contains the trees Irvingia Barteri and I. Smithii. These yield the Dika nut, or, as it is sometimes called, Gaboon chocolate. The sun-dried kernels keep in a perfectly good condition for some time. According to the investigation of the Imperial Institute[20] the kernel contains about 43·5 of “Dika fat.” It would be useful either for soap or for candle making, and be worth from £25 to £27 per ton, and the Dika kernels are valued at from £10 to £12 per ton. Locally, however, they are often worth as much as this, but no doubt increased production would mean a reduction in price. So far the tree has only been planted in isolated instances, and otherwise is a forest tree which has been protected by the native for the value of its fruit. The decortication usually takes place near the tree, or in an open place where the nuts are split in half with a sharp matchet, which releases the kernel in the centre, and though often cut in half by this method, it apparently does not mean a large loss of oil to the kernel. According to the analysis of the Imperial Institute[20] the kernel showed:

Apparently an oil seed, probably Philiodiscus, a member of the Sapindaceæ family, has been examined at the Imperial Institute and has been found to contain a non-drying oil, which was free from taste and smell. It should, therefore, be of value for eating or for making a white soap.

Sapotaceæ, Butyrospermum Parkii.—In recent years larger quantities of Shea nuts, which are the product of this tree, have been exported from West Africa, especially Nigeria, as also Shea butter, which is manufactured locally from the nuts. In the varieties Tengba and Bomo the quantity varied from “54·5 per cent. to 48 per cent.,” and these were obtained from the Southern Provinces of Nigeria. In the two varieties exported from the Northern Provinces, those known as Eko showed a length of nut varying from 1·5 to 2·5 inches, and the Giddouchi variety 1·4 inches long. Owing to the wide prevalence of this tree much larger quantities could be exported, but many of the forests containing it are situated far away from means of transport, and no very suitable method has yet been found of manufacturing the butter on a big scale locally. At present it is made by certain women who know the process, which takes nearly three days to complete. According to the Imperial Institute the results of the analysis of Shea butter are:[21]

The fat obtained from the Northern Provinces and the Gold Coast shows very similar contents.

Mimusops, sp. Djave?.—The nuts of this species closely resemble those of the Shea Butter Tree. The nuts are a light-brown colour, about two inches long, and one to one and a half inches in diameter, with roundly pointed ends. Rather more than half the surface of the nut is smooth and shiny, and the other half is rough and dull, and the whole of it is very hard. When dry it is, however, comparatively easily separated from the kernel. The fresh kernels are cream-coloured. According to the Imperial Institute[21] the yield of fat extracted by solvents is 60·2 per cent., or 37·7 per cent. from the whole nut. The fat is solid at ordinary temperatures. In 1913 some of these nuts were shipped from the Cross River and were valued in Liverpool as Shea nuts, only at a rather lesser rate. According to the Imperial Institute the analysis showed:

Specific gravity at 100/15·5° C. | 000·860

Saponification value | 187·6
Iodine value | 056·2
Hehner value | 095·4
Reichert-Meissl value | Nil
Unsaponifiable matter | 002·6 approx.
Titer test | 047·8° C.

Dumoria Heckeli? (Baco or Abaku).—Although the Gold Coast name is given, these nuts are also found in the Oban forest. The nuts are large, considerably longer than those of Mimusops, but rather thinner. They are of a pale-brown colour, with a thick, hard, woody shell, most of which is smooth and shiny, only one small part of the surface being rough and forming almost a nodule. According to the Imperial Institute[22] analysis of the Gold Coast samples, the whole nuts contain 21 per cent. of fat or 60·5 per cent. in the kernels alone. The fat is solid and of a creamy white colour. The soap-makers reported that it was about equal to middling quality palm oil. It is also stated that dried kernels in good condition would be worth £13 per ton. According to the Imperial Institute[22] analysis the fat showed:

Specific gravity at 100/15·5° C. | 000·855
Acid value | 034·7
Saponification value | 188·4
Iodine value | 051·3

Unsaponifiable matter | 001·3

The small nuts of Mimusops multinervis and M. lacera have not been examined as to their oil or other content. The hard nuts of M. lacera appear to contain a fair proportion of oil.

In this family, too, are the nuts of Chrysophyllum Africanum and other species, for which a use has yet not been found. Finally, there are the numerous and fine seeds of Omphalocarpum elatum, known as Ikassa by the Benis, which are probably also oil-bearing.

The next important family is the Olacaceæ, Heisteria parvifolia, known as Ikereoha by the Benis. It yields an edible nut which is white on the exterior and has a black-coloured shell over the actual nut inside. It has not yet been exported or valued. The Benin and other natives are very fond of eating it.

Then there is the nut of Ivialegbi (Benin), which is edible and has a pleasant taste. It is rather smaller than the Gaboon nut, and its surface is slightly striated from the sharp point of the nut to the base.

In this family is found, too, Coula edulis, or the Gaboon nut. This is chiefly found in the Cameroons, but owing to similarity in the vegetation it is very probably growing in the Oban forest of the Anom range. The shell of the nut is very rough, and the outside is smoother than the inside. The shell can be cracked comparatively easily with a somewhat powerful blow with a hammer or axe-handle.

From the Anonaceæ:

- Monodora tenuifolia, African Nutmeg.

- M. myristica, var. grandis, Calabar Nutmeg.

- M. brevipes, Yellow-flowering Nutmeg.

None of these nutmegs have yet been placed on the European market. Although they are all much smaller in size than the nutmeg of commerce, a proper examination would reveal any value they might possess.

Although the Myristicaceæ, Pycnanthus Kombo, yield fat-bearing nuts, they have not been exported to the English market. The nut is the size of a small oval plum. The outer husk is hard and thick, but is comparatively easily broken. The inner nut is covered with a red aril spread out over it, similar to the mace over the common nutmeg (Myristica fragrans). The kernel is white inside, with dark rays penetrating it from the outside. The tree is very prevalent, and yields a large number of nuts. According to the investigation of the Imperial Institute[23] “the yield of solid fat was 54 per cent. It has an orange colour and a bitter taste.” The fat was stated to be suitable for soap and candle making and the meal as a manure. In Sierra Leone the nuts were known as Kpoye, and are identical with those known as “Kafu.” According to the chemical analysis made at the Imperial Institute the following results were obtained:

Specific gravity at 100/15° C. | 00·886

Of the Meliaceæ there is Carapa Guineensis (C. procera, D.C.), which yields the Carapa oil. The nuts are roughly tetrahedral in shape, having a rough reddish-brown shell enclosing one large kernel covered with a pale-brown papery skin. Good kernels yield about 57 per cent. of oil by extraction with solvents and 46·7 per cent. by pressure (27 per cent. on cold and 22 per cent. on heating); it is of a pale-yellow colour and has a bitter taste. The commercial value of the oil was stated in 1907 to be £20 10s. per ton according to the valuations made by the Imperial Institute,[24] and from the same authority we find the Carapa cake is of a very low manurial value, and is only stated to be worth about £2 per ton. Some dark-coloured kernels were bought in 1909 at £11 5s. per ton, and light kernels at £11 10s. per ton. According to the Imperial Institute the results were as follows:

Apocynaceæ.—Although the seeds of Funtumia elastica yield oil, it was not favourably reported on. Perhaps now, with the greater value of all the oil seeds, some use could be made of it.

Ebenaceæ, Diospyros Barteri.—This yields the Ebony nut, which is small, but edible. The Benin natives are very fond of it. It has not been exported.

Diospyros crassiflora or Diospyros dendo have a fruit about the size of a large green plum, which contains four long, thin, almond-like nuts, which have rather a bitter taste. Although evidently oil-bearing, they have not been properly examined or tested as to the exact content of oil or other products.

Rosaceæ.—Although the Chrysobalanus sp., or Niko nut, is comparatively well known, it is by no means fully utilized. Then there is Parinarium Gabunense, yielding the Mahogany nut, of uncertain value.

Anacardiaceæ.—The Anacardium occidentale, yielding the Cashew nut, is so far only utilized near Lagos, where it is growing as a garden escape. No proper plantations have yet been made of this tree.

Amongst the Palmæ, besides the Oil Palm, we have the Bottle Toddy or Fan Palm, Borassus flabellifer, yielding three or four nuts in each fruit. These are oil containing, but of unknown value. Considering the large areas in all the West African Colonies where the Fan Palm is found, some use should be made of the large number of nuts produced.

Then we have Hyphæne, the Doum Palm, which yields a nut used for making buttons. Here, again, the large quantities which are found in Africa ensure a steady amount of produce being placed on the market, provided a remunerative price is always paid for the nuts. Finally there is Phœnix dactylifera, the Date Palm. Although this is more of a fruit than a nut, it is included here, as it is found in the forest groves of the North. Considering the value of its produce and the constant demand there is for it, a wide extension of its area of cultivation is to be recommended.

Ochnaceæ, Lophira alata.—This is the dwarf Red Ironwood tree, which yields the “Niam” fat or “Meni” oil. The fruit is roughly conical, consisting of a reddish-brown fibrous shell, enclosing one kernel. The kernel is conical in shape, and about five-eighths of an inch in width. The inside is a pale-yellow colour. The fruit has two uneven-sized wings, the larger being over an inch in length and nearly half an inch in width. According to the Imperial Institute[25] the fat is semi-solid and of a yellowish colour. The kernel contains 31·1 to 43 per cent. of fat. The fat is suitable for soap-making.

According to the analysis of the Imperial Institute the results were as follows: For soap-making it is considered to be of the same value as palm oil, i.e. in November 1911, at Liverpool, £30 to £31 per ton. The cake obtained from it closely resembled Shea-nut cake and was of a similar value, i.e. about £3 per ton in Liverpool. The decorticated kernels, which contained about 40 per cent. of oil, were valued at about £10 per ton c.i.f. at Liverpool in October 1911. These kernels should find a ready market in Europe for soap-making, and the cake to be used as a manure. As the tree is one of the commonest in the dry-zone forests, ample supplies of the nuts should be always forthcoming, providing an adequate price to pay for the cost of production is paid for them.

Closely allied to the above is Lophira procera, the Red Ironwood Tree, which yields the Kaku or Ebba kernels. The fruit is usually more sharply conical in shape than that from L. alata. The fruits are small, owing to the fact that these large forest trees grow closely amongst others, and the fruits are not so fully developed or filled out as those of L. alata. L. alata usually grows in the open freely, or at most only just touching a neighbouring tree, and thus the fruit has ample light for its development. According to the investigations of the Imperial Institute, the nuts were found to yield 55·2 per cent. of fat, which was solid and cream-coloured. Owing to the fact that this is a larger yield than that obtained from the nuts of L. alata, the decorticated kernels were valued at £12 per ton c.i.f. Liverpool. This tree is one of the most prevalent in the evergreen forests of Nigeria, the Gold Coast, and Sierra Leone, so that very considerable amounts of the seeds could be obtained, provided a remunerative price is paid to cover the cost of production. According to the analysis made at the Imperial Institute[26] the kernels contain:

Specific gravity at 100/15·5° C. | 000·859
Acid value | 011·6
Saponification value | 190
Iodine value | 060
Unsaponifiable value | 000·8

Guttiferæ, Pentadesma Butyracea.—The Tallow Tree. From this a large number of fat-yielding kernels are obtained from each fruit. The nuts are irregular tetrahedral shape. The shell is not very thick and easily broken when the nuts are dry. When fresh the kernel is lightish-yellow in colour, and the nut is brown. According to the investigations of the Imperial Institute the fat obtained is of a pale-yellow colour, and has a pleasant smell and taste. In smell, in fact, it is very much like Shea butter.

On analysis it showed:

Specific gravity at 100/15·5° C. | 000·859
Acid value | 003·6
Saponification value | 190·1
Iodine value | 041·8
Titer test | 050·7° C.

The samples from the Southern Provinces of Nigeria showed rather a lower saponification and iodine value.

From its appearance and chemical constants it seems possible that this fat might be used in the manufacture of edible fats. The kernels were valued, when in good and dry condition, at from £8 to £10 per ton in the United Kingdom.

Allanblackia floribunda.—The numerous nuts or kernels from the large fruits of this tree have not yet been used for any commercial purpose. They appear to contain an oil. In this family, too, there is Ochrocarpus Africanus, which has the large edible fruit known as the African Mammee Apple. This also yields large nuts of an uncertain value, which are apparently oil or fat bearing.

Garcinia conrauna.—The nuts of this, the false or bitter Cola, besides yielding an edible fruit, are used locally, but further investigations would show whether they would obtain a regular market as an export product.

Polygalaceæ, “Cheyi” seed, Polygala butyracea, Heck.—This is a common herbaceous plant of West Africa. The seeds yield a valuable edible fat. They are about a fifth of an inch long and a tenth of an inch broad. The seeds are of a brownish-black outside and a greenish-yellow inside. According to the investigations of the Imperial Institute “the seeds yielded 39·7 per cent. of a soft yellowish fat. The taste of it was pleasant, and there was no odour.” According to the Imperial Institute analysis the “Cheyi” fat showed:

“The edible fat manufacturers stated that ‘Cheyi’ fat was suitable for their purpose if it could be proved that it did not contain a poison, and valued the seeds at £13 to £14 per ton. The oil-seed crushers valued the seeds at £12 per ton in the United Kingdom.”

N.O. Bixaceæ, according to Thonner, Flacourtiaceæ, Oncoba echinata, Oliver.—This tree bears a large number of seeds, which are known as “Gorli” seeds. The seeds are long and irregularly shaped, and vary from a quarter to three-eighths of an inch long, and from one-eighth to three-sixteenths of an inch broad. The stiff husk is brown in colour. The seeds without husks are white, waxy and soft. According to the Imperial Institute investigations the seeds contain 46·6 of fat, which is hard, white and crystalline. Although the soap made from it was satisfactory, it did not lose the very peculiar odour which the fat has. The cake and fat cannot be used as a food because of the large amount of chaulmoogric acid contained in it, an acid which causes vomiting. The fat might possibly be of value in candle-making. According to the Imperial Institute analysis the seeds showed:

The nut of Ogbogo, a Benin tree, is as yet unvalued, though it appears to be an oil-yielding fruit. There is, too, the long almond-shaped nut of Oktobun. Although it has a somewhat hard shell, the nut is very large in proportion, and the kernel seems to be rich in oil. So far no use has been made of it.

CHAPTER XII

THE OIL PALM AND PALM KERNEL INDUSTRY

1. Æsthetic Aspect.—A most familiar sight to everyone visiting a farm in the southern part of Nigeria is the charming grace of the fronds of the Oil Palm in the clearings near the house. The long, straight, cylindrical, undivided stem, crowned by a large tuft of broad green palm leaves, easily distinguishes the Oil Palm (Elæis Guineensis) from the Tombo (Raphia vinifera), which has a thinner stem, clothed from the base to the top with 40-feet long heavy fronds, the undersides being silvery and the upper part light green. In certain times of the year huge bunches of yellow grape-like fruits hang quite 4 feet down from the narrow crown of this tree. It is most noteworthy that the Tombo Palm is found growing in or near a swamp, and only occasionally planted as an avenue tree on drier land, whereas the Oil Palm is usually found in the hard and drier ground and only occasionally in the swamp. The Oil Palm is much larger than another Wine Palm, Raphia Hookeri, which is similar but smaller than Raphia vinifera, the growth being similar but the seeds smaller.

Raphia Ruffia is a small swamp palm, with practically no stem, but a large number of long, thin, and somewhat light, pendulous fronds.

Most visitors to West Africa are quite familiar with the huge casks of orange-coloured or yellow oil, which often leaks on to the deck of the ship, and the peculiar, rather nauseatingly pungent odour of the “sweating” kernel bags.

1a. General Description of the Oil Palm Tree, Fruit and Nut.—From the railway carriage we can see numerous groves of Oil Palms, as well as isolated specimens, almost continuously for the first 60 miles from Lagos, and more isolated for the next 180 miles. With few exceptions the Oil Palm is a single stemmed tree, one notable forked tree being seen on the northern side of the Nigerian Railway, a little more than three miles before reaching Ibadan. In this case an oil palm nut may have become embedded in an old leaf stalk sheath and subsequently sprouted, thus forming a separate tree growing on the other, which in the course of time has become joined up.

It will be noticeable that in passing through the heavy forest near Olokemeji few or no Oil Palms are seen. This forest, however, is situated really within the area of the natural distribution of the Oil Palm. The Oil Palm, however, needs a good deal of light for its development, and those trees seen in the heavy forest are very tall, often over 100 feet high, with comparatively short leaves and a small number of them forming the crown of the tree (see illustration 102). On the other hand, wherever a clearing has been made in the forest, for instance near Awowo, the older Oil Palms are shorter in stem, often being not more than 20 feet in height. Another instance of this is seen in the farms near Badagry, where the trees are often only 15 to 20 feet high, and the stem itself only 10 feet in length. In each of these cases it will be noticed that the trees are standing quite free, with no overhanging vegetation. From the first they have been in this position, and the leaves have had room to spread almost 20 feet all round, thus giving the tree the maximum amount of moisture and other food material.

Amongst these trees, Oil Palm seedlings will be seen to spread out over the ground almost at once, even when only the secondary and tertiary leaves have grown. In the forest, however, the leaves go almost straight up, and only after some years have elapsed spread more as they dominate, or try to overgrow, other seedling forest trees.

2. Botanical Description of Tree, Fruit, etc.—An Oil Palm starts male flowers when three years old, and these are borne one to three years before the female flowers appear. The male and female flowers are both found on the same tree, the male above the female in the axils of the leaves. There are two cycles of leaves younger than the female flower. The Oil Palm fruit is formed first by the kernel surrounded by shell, then the fibrous pulp containing the palm oil. The ripe fruit is of a brilliant brick-red colour, the unripe fruit being always black at the point and only red near the base, where it is covered by neighbouring fruits. When ripe they fall from the bunch, and it is especially noticeable that each bunch of fruit grows out of alternate leaf axils, alternating also with the whorls or cycles of growth (illustration 60).

The female flowers are very minute, and in the earlier years each bunch is rather smaller than a man’s hand. The centre of the flower is orange, coloured with a bluish tip, and scarcely lasts a week. On the other hand, the male inflorescence is like a compact horse’s tail, composed of closely packed pollenated stamens. Owing to the different years in which the male and female inflorescence appear, it is probable that cross-fertilization takes place.

2a. Distribution of the Oil Palm.—The Oil Palm is found from Sierra Leone to Lake Chad, down to Ambriz, and eastward to the borders of German East Africa.

The Palm Belt, according to Millbourne, is 3,000 miles in length, and varies from 150 to 300 miles in width.

It is estimated that there are six or seven million Oil Palms behind Loanda inland, though this sounds rather exaggerated.

In Nigeria it is most widely distributed in the Southern Provinces, and the densest “stands” are found in each of the river basins wherever the forest has been cleared (see illustration 103).

Wherever the dry season is very prolonged and the locality shows a shallow soil, overlying laterite or rock, the Oil Palm first of all appears after the forest has been cut down. After a few years the trees are subject to annual grass-fires, and while still bearing fruit they begin to fail and scarcely last half the ordinary period of their life. Localities of that nature are found in the Afikpo, Onitsha, Ifon, and parts of the Ibadan districts.

The Oil Palm is also one of the first trees to appear after the mangrove swamp and Tombo Palm region is passed in going through the forest zones from the coast inwards.

2b. Varieties of the Oil Palm.—These, according to Professor O. Beccari, of Florence, are as follows:

- Elæis Guineensis.

- Var. albescens. White Oil Palm. Abe-fita or Abe-fufu (Gold Coast).

- Angulosa. Oleporo Eyop (Old Calabar).

- Ceredia. Adi-be (Gold Coast).

- Communis. Udin (Benin).

- Communis forma, dura. Ade-pa (Gold Coast).

- Idolatrica. Sacred Palm. Abe-Obene (Gold Coast).

- Intermedia.

- Macrocarpa.

- Macrocarya. Abubube (Gold Coast).

- Pisifera.

- Repandra. Kessede.

- Rostrata. Mbana Oyop (Old Calabar).

The Benin people differentiate the Udin or ordinary palm from Ogedin or the King Palm on account of its having smaller bunches of fruit, each fruit being longer and having a softer shell. They also treat Evirommilla or the Palm of Everlasting Life as a separate species. The Yorubas, however, consider that there are three species of Oil Palm.

According to the German experiments in the Cameroons, the Lisombe or soft-shell Oil Palm does not come up true to type, approximately only 5 to 10 per cent. growing to the true variety. From the locality in which the Lisombe Palm was and is found, it looks as if the high rainfall (over 300 inches) had really been one of the main factors in evolving this type of Oil Palm. In fact, natives who know the ordinary Oil Palm and the soft-shell Oil Palm say it is rather a matter of taste as to which is the better of the two. Apparently it depends on what commodity the native is dealing in, kernels or oil, as to whether it pays better to get plenty of oil, and obtain the kernels more easily from the soft-shelled Oil Palm, or an average amount of oil and larger kernels obtained with more difficulty from the ordinary Oil Palm. On the whole, the Lisombe Palm does not seem to yield on an average more pericarp oil than the ordinary Benin or Yoruba Oil Palm growing in a farm in the usual moist-zone climate. Certainly the kernel of the Lisombe Palm is much smaller than the ordinary Oil Palm. A further point to be considered, too, is that the bunch of Lisombe Oil Palm fruit is smaller on the average than the bunch of the ordinary Oil Palm.

However, it may be noted that the natives of the southern part of the Ogoja district, especially the Ndeh and Befun people, plant a species of soft-shelled palm near the villages. Of course, in this locality the Oil Palm is not found in very large quantities, and the seeds for these groves were obtained from a good distance away, probably near the Cross River.

3. The Growing of the Oil Palm—Distribution of Seed by Farmers, Parrots, Monkeys.—In the forest country a clearing is made some distance away from the village by the native to make a new farm. In clearing and cutting down the forest, few or no Oil Palms are met with, so that the farmer’s wife brings palm fruit or oil to the new farm, in order that they may have palm oil to eat. Having made the oil, the nuts are put out in the open to dry, with the intention of their being cracked later on. However, they lie about some months, and rodents of various kinds, such as rats and the hyrax (a squirrel-like animal), carry some of these away into the farm. Some farmers, too, pick up a few and scatter them over the farm. In the course of a year or two Oil Palm seedlings appear, where they are left amongst the other vegetation when the farm is abandoned. In this way, instead of the original thick forest there is a more or less dense grove of young Oil Palms. In other places the parrots may bring nuts from the neighbouring forests or other old farms, and these, falling in the clearing, also help to make a palm forest.

The native also, after he has picked the bunches of fruit, puts them down in some convenient place on the roadside. Some of the nuts become scattered, which subsequently sprout and form additional groves of palms, especially where the larger trees near the roadside fall, or are cut down, thus giving more light to the young seedlings.

Again, when the bunch of fruit is ripe on the tree, it is not often immediately cut off, and many of the ripe nuts thus fall to the ground. These subsequently grow, forming almost thickets of Oil Palms, instead of the one from which the original seed was obtained. A similar process takes place on a bigger scale in the more distantly situated forests, where the natives do not collect the fruit at all. Here, all the nuts gradually fall off the tree, more or less forming a circle 10 to 15 feet away from the trunk. If any clearings take place in these localities, they rapidly appear to become filled up with Oil Palms, which in reality were already there as little tiny seedlings amongst the herbs and undergrowth, ready to make use of any additional light or growing space to develop fully.

4. Fruit-bearing Age of Oil Palm.—Under these conditions, where the seedling Oil Palms stand only a few inches, or at the most 4 or 5 feet apart, the growth is very constricted, with the result that no flowers or fruit appear before the fifteenth or twentieth year. Each stem is excessively thin, and tends to grow upwards like an ordinary forest tree, rather than forming a very short, almost negligible length of stem, but nearly 1 foot in diameter, as is typical of the palm family in the earlier years of its growth. Contrary to the above, where the Oil Palm comes up in a more open place the leaves do not tend upwards, but outwards, arching over with the leaf stalk at an angle of about 45° to the ground. The leaves themselves, instead of being long and thin and with a long length of green stalk, soon spread out fully 20 inches on either side of the main stalk, thus giving the plant more food material and making it grow more quickly. Then, in the fourth or fifth year, bunches of fruit, each containing from twenty-five to thirty nuts, are formed out of the female flower. Each bunch, which is the size of a man’s fist at this age, increases to nearly 2 feet in length and 1 foot in diameter at maturity. However, each bunch of fruit, having been formed against the stem of the palm and in the axil of the leaf stalk, is very much compressed, especially at the base. As an experiment, when the fruit is beginning to ripen, the leaf stalk just immediately below the base of the fruit stalk is removed; gradually then the bunch of fruit droops a little and develops more fully at the base, owing to having more space. More light thus reaches the fruit sideways, and the period of ripening is accelerated by three weeks.

5. Oil Palm Plantations and Crops.—As a result of the greater spreading out of the leaves of the young palm and the more sessile habit of the stem in the earlier stages of growth, light penetrates more intensely into the fruit-bearing axils of the tree, thus increasing the size of each bunch.

In the Calabar Arboretum, some Oil Palms were cleaned and the ground thoroughly cultivated in two successive years. In the first year one tree bore fourteen bunches of fruit, and in the second year it bore twenty-two bunches. No manure was placed on the ground, and the soil was distinctly poor and sandy—in fact, the natives in the locality said the land was of no use and could not be used for farms (see illustration 102).

In another case, in Benin, the Oil Palms, which were first sown at stake and subsequently transplanted, bore fruit in the fifth year. Contrary to expectation, the transplanted Oil Palm seedlings developed the secondary and tertiary leaves within a few months after the transplanting had taken place, whereas those sown at stake continued with only two spiky leaves for almost the first year of their growth. As the tree gets older, the number of bunches of fruit borne gets less, though each bunch is fully five times the size of the first fruiting bunches of the fifth year.

In most districts about five bunches of fruit ripen each year, and each bunch bears from 1,200 to 2,000 nuts (from the best trees). It is always noticeable that the palms growing in the open, free from surrounding trees, produce the finest bunches and the greatest number of nuts. On this point of the yield of bunches per annum further investigations are necessary, as it is by no means proved that an average of five bunches per annum is the maximum number for a mature Oil Palm.

In the Togo Plantations (251 acres), it was noticeable that in the more favourable climate of Atakpame and Bassari the Oil Palm bore in the fifth year, whereas in the drier climate of Jendi the trees first bore fruit in the seventh year. In illustration No. 19 the amount of growth shows clearly from year to year, more especially in the difference in the size of the leaf. The relative shortness of the stem is distinctly seen, showing up when compared with the natural forest-grown Oil Palms in illustration 20. In addition, there is the Agu Plantation in Togo. Thus far very few Oil Palm plantations have been made, those in the Cameroons being the most extensive. However, these are almost too young, or to some extent mixed up with the original forest-grown Oil Palms, for conclusive results to be shown.

In the Central Circle in 1906 a communal plantation was made at Okokwo, but the natives have not yet found the necessity of extending it.

Between the Kwa and the Akwayefe Rivers, going along the Akpaboyo Road, the Oil Palms are so evenly distributed that they almost appear to be one great plantation. However, the locality is very favourable to the Oil Palm; the original forest has been largely cut down and the natives have allowed the Oil Palms to stand wherever they did not hinder farming operations. Owing to the fact that the Oil Palm has spread, and is spreading, in those parts of the Southern Provinces of Nigeria and elsewhere where the rainfall is between 60 and 150 inches per annum, there has thus far, from the native point of view, been no incentive to plant more Oil Palms. In fact, with the increasing amount of general work going on, combined with the comparatively high price obtained for palm oil and kernels, there is less necessity for the native to gather all the palm fruit that has grown. It has been noticed that the cultivated Oil Palm, or Oil Palms growing in an open place, only reach about one-quarter the height of the forest-grown Oil Palms, which attain a height of over 100 feet (see illustrations 60).

With cultivated trees it is possible in the earlier fruiting years to stand on the ground and gather the fruit from the palms, and even in later years only a short ladder is necessary in order to reach it. It is really on this problem of the height of the palm-tree that the chief collection of the fruit depends, and also the total output from the Oil Palm forests. Further investigations are necessary to decide as to how far it is possible to retard the height-growth of the Oil Palm for as long as possible, while accelerating the radial growth, or at any rate increasing the thickening of the stem. Varying planting distances have been tried, such as 16 feet 3 inches each way, 17 feet 9 inches in the German experiments in Togo, but 23 feet each way in the Cameroons. In one case teak (Tectona grandis) had been mixed with it. On the whole, in ordinarily favourable localities, a planting distance of 24 feet each way appears to be the most suitable. For the first five to ten years at least agricultural crops could be grown in between, until the Oil Palms had spread out so as to cover the ground almost entirely. Few or no experiments have yet been undertaken in selecting and planting only the biggest nuts of the most prolific variety, which, according to Mr. Farquhar’s report, The Oil Palm and its Varieties, is the A-sog-e-jub, which contains 48 per cent. of pericarp oil.

It has at any rate been demonstrated by the natives that Oil Palms which have been tended yield bigger bunches and bear larger nuts, but only by actual experiments in selected areas or plantations can it be proved exactly how much more produce is obtained, and the extra financial yield over and above the increased cost of cultivation, etc.

According to various commercial calculations, it has been estimated that only £1 per ton can be paid for the ripe fruit at the oil or kernel crushing mill.

Owing to the comparative wide distance (24 feet) at which the Oil Palm should be planted, for the first few years it is possible to plant some catch crops. One of the cheapest ways of forming Oil Palm plantations would be to take over an area fairly well covered with self-sown Oil Palms up to 12 or 15 feet in height. After choosing the best and marking these, the rest should be gradually thinned out by tapping them for palm wine, which could be sold. A crop of water-melon, or Egusi bara (Citrullus vulgaris) of the Yorubas, could be planted over two-thirds of the ground between the Oil Palm plants and trees, leaving sufficient space for their growth and about equal to the spread of their foliage in each case. After this crop has been gathered in August or September, a crop of Awuje (Yoruba name) beans could be planted, which would again be ready for picking by December. In each case the haulms and dried leaves of the plants, after the crop is gathered, should be burnt in small heaps and the ashes scattered over the soil. At the beginning of the following year the ground could be got ready again and a crop of maize sown in a similar way, covering a half to two-thirds of the ground between the plants. This could be followed by another crop of water-melon, which would act as soil-covering during the rainy season, and again another crop of beans in the autumn. In turn this could be followed, after similar treatment as before, at the beginning of the third year, by a crop of yams (Dioscorea sp.). Probably owing to the growth of the palms it would only be possible to have one row down the middle of the line between the palms. The species of yam should not be too large, so that the ridges or yam heaps could be heaped up if necessary with a plough and not by hand, as is usually done. The following autumn another crop of beans could be planted, and the next year, if the soil was light and suitable, a crop of ground nuts could be grown as a double row between the Oil Palms. In the following autumn a crop of beans could be grown again. In the following year, the fifth, some of the Oil Palms would be in bearing and yield the first returns. Bananas could then be planted as a single row between the lines of Oil Palms and would bear in the following year, thus supplementing the second yield of oil and kernels. By these means the whole cost of cultivation should at any rate be covered by the sale of the produce grown, partially to the labourers and otherwise outside, for export, and perhaps even a profit made over and above the cost. In the eleventh or twelfth year the bananas would be practically or entirely covered by the Oil Palms, and thus have to be cut down and to some extent uprooted. Their leaves, however, would form a good mulch for the soil, and at any rate act as an effective soil-covering, thus preventing the growth of weeds.

It is doubtful whether it would be wise to plant bananas right from the start in even one line, not to speak of two amongst the Oil Palms, owing to the extraordinary amount of moisture taken from the ground by the banana. In some cases, on the better soils, they might be introduced in the third year. Cassava, Manihot utilissima, is rather too exacting a crop to be suitable for planting amongst the Oil Palms. It is very liable to impoverish the soil. Then, too, as far as Nigeria is concerned, it is not a very paying crop, yielding at the most about 14s. per acre after all expenses have been paid. In all the above cases we are taking it for granted that the Oil Palm has been planted at, or thinned out to, a distance of 24 feet between each tree. On the poorer soils the distance might no doubt be 18 to 20 feet, and on the very best probably a distance of 30 feet will not be found excessive. Where lime or other manure is available and comparatively cheap, and in some cases heaps of humus from the outskirts of villages, it would pay to put this on the land in the late autumn when the ashes from the previous crops are being spread on the land. In addition to these crops, careful surface cultivation round each Oil Palm is essential, not only to prevent the growth of weeds but also to keep the aeration of the soil good, prevent the desiccating effects of the dry season, and accelerate the growth of the Oil Palm. Besides planting these crops by directly paid labour under European supervision, using as many modern labour-saving appliances as possible, parts of a plantation could no doubt be let out at a nominal rent to the natives, even to some of the labourers, to work it in their own time, but only planting such crops as would fit in with the rotation and not lead to the impoverishment of the soil. Apparently the greatest danger to the tropical soil is to leave it bare for any length of time. In the rainy season all the mineral matter and tilth is liable to be washed away, and in the dry season fissures are formed in it, and if it is at all argillaceous it is liable to be dried out for a depth of over 2 feet. Constant covering is thus necessary to ensure the growth of the Oil Palm.

6. Destruction of Oil Palms.—This is carried out for the following purposes: For farming (Onitsha) and making palm wine. Sometimes many of these trees are destroyed by fire in the Ahoada Okigwi, North Owerri, Afikpo, Abakaliki, Ogaya, and Obudu. Grubs, too, are a very frequent source of destruction among them. The trees are tapped in the Yoruba country to obtain palm wine, but it is not known exactly to what extent this reduces the yield of palm oil and kernels. On the whole it is harmful, owing to the fact that insect and other pests can obtain entrance to the tree through the holes made in tapping it. With the steadily rising price of gin the tapping of the Oil Palm is increasing annually, resulting in a destruction of many thousand trees each year, chiefly in the Obubra and Ikom districts, and to a lesser extent by tapping the trees in the Yoruba country. Wherever the rainfall does not exceed much over 50 inches and the soil of the locality is shallow over laterite or some rock formation, the fires become usually an annual occurrence. The Oil Palms which at first come up on the clearing of the forests then get burnt, and after a few years cease to grow faster than the leaves are burned each year, and subsequently die. In a similar way the young seedlings which may come up are very easily killed by these annually recurring fires, and thus the whole district is impoverished. This process can be seen going on in parts of the Afikpo, Owerri, Abakaliki, Onitsha, Ifon and Ibadan districts. It is a serious menace to the future development of the Oil Palm industry.

6a. Native Method of Collecting Fruit.—The native, to collect the fruit, climbs the tree with a specially made rope round his waist, by which he gradually hoists himself up. With a rough chisel, like a piece of iron with a handle, he first cuts off the leaf just above the fruit and then severs the bunch, letting it fall to the ground. Many of the fruits drop out in the transit, but these the native does not trouble to gather up.

It is usual for the Chief to close the forest for a certain time until the Oil Palm fruit is more or less ripe, and then the natives can gather it all at the same time. Owing to the difference in the time of the ripening of the individual fruits at the top of the bunch and those at the base, many fall to the ground before the bunch is actually cut off the tree. These are not gathered up, and are taken away by rodents or birds, or come up in the same place.

7. Native Method of Making Oil and Kernel Inspection.—The native cracks the palm kernel almost entirely by hand, the nuts being first dried in the sun on the ground in open spaces, surrounded roughly with little billets of wood, or in small sheds. When dry, they are taken out and cracked on rocks (if they happen to be in the neighbourhood) with a piece of stone in the cracker’s hand. Should the spot be devoid of rock, a piece of wood or stone takes its place, and then a piece of iron or stone is used by him in the right hand. Good workers, usually small girls or women, can crack about 15 to 20 lb. a day in this manner.

An inspection fee on palm kernels and oil has undoubtedly helped to improve the product immensely and not reduced the output.

The kernels are picked out at the same time, the shell remaining more or less where the nut is cracked. A certain amount of shell adheres to the kernel, and if it is an excessive amount the native picks it off. Anyhow, when he reaches the factory the shell contents must not exceed 5 per cent. Although they are not actually dried, they are usually kept in a dry, cool place, until sufficient have been collected to sell either in the local market or straight to a European factory. The inspection of the palm produce, both oil and kernels, takes place at the factory, where the produce is bought by the Inspectors of Produce under the Customs Department.

7a. Kinds of Oil.—Most of the oil is soft, but as some hard oil is made which is worth £3 or £4 less per ton than the former, owing to its having about 8 per cent. less of glycerine, and both are made by a different process, both methods will be described.

Hard oil is made chiefly near Onitsha and Ikpa markets, east of the Niger, by the Ibos, and the following is the process employed in those districts.

The fruit is left on the bunch in the bush, covered with leaves, for ten days; it is then brought into the village or place where the fruit is cut or knocked off the bunch. Large earthenware pots with a little water in the bottom are then filled with the fruit; this is then heated, but the water does not actually boil, or even steam very much. The fruit is then taken out and beaten in an old canoe or hard mud trough until all the fibre is fairly well macerated and detached from the nut. The whole mass is then placed in a shady place for four days to enable the oil to “get strong,” as the local people say. On the fifth day the oily fibre and nuts are placed in the trough again, and cold water is poured in until it is about a foot deep. The whole mass is pounded with the bare feet of children, girls or women, so that gradually the oil becomes detached from the fibre or from adhering to the nuts, and floats on the surface of the water, especially near the edges of the trough. It is then skimmed off with the hand and put into calabashes. The nuts and fibre having sunk to the bottom of the trough, the oil is left comparatively free from impurities. The oil in the calabashes hardens to much the same degree as dripping, and is ready for sale.

On the banks of the Niger, where it is sold to European firms, the natives are often obliged to boil it to purify it still further, and to enable it to be poured into the puncheon in which it is shipped to England. This oil, even when cleaned and boiled, has a bitter taste, which the natives do not like when they have been accustomed to soft oil. When this oil arrives in England it is quite hard again.

Soft oil is made in Nigeria, as well as in Sierra Leone and the Gold Coast Colony. The Lagos and Benin oil is the best, so the method employed in that part of the country will be described. The fruit is cut off the tree in much the same way, but the loose fruit is generally collected from the ground as well as the bunches, which are then carried to the oil-making place, which is usually situated near a running stream for the convenience of the manufacture of the oil. The fruit is cut or knocked off the bunch, cleaned of any extra stalk or dirt, and placed in earthenware pots, in the bottom of which is a little water. These pots are then put over a bright fire until the water not only boils, but has quite steamed away. It is then considered that the fruit is thoroughly soft and ready for crushing, when it is placed in earthen troughs or old tree trunks which are used for this purpose. Cold water is then poured over the fruit to about a foot in depth, and the fruit is pressed by the feet of women or girls standing in the trough. The oil rises to the surface of the water, is skimmed off with the hand or a flat piece of wood, and put into earthenware calabashes; all fibre is thoroughly squeezed and rinsed to obtain the oil out of it. The oil is now thoroughly boiled, and when quite thin and of a reddish-orange colour is poured off carefully into clean pots. A fine residue of fibre and particles of dirt remain in the pot in which the oil was boiled; this is used for native lamps by dipping a twisted fibre into it.

The clean soft oil is now ready for sale, and is carried in old kerosene tins or other receptacles to the nearest market. Despite the very large loss which occurs, owing to the breaking of calabashes on the road to market, still very large amounts are carried in vegetable calabashes or earthenware pots. By the time this oil reaches Europe it is partially hardened in the cask, though usually there is a certain amount of liquid on the top.

Sale of Produce.—The palm oil is sold by the kerosene tin (one gallon), by the keg, or by the puncheon. It is also sold by the bottle in the markets for local use.

The palm kernels are sold by the calabash in the districts further away from the markets, but more usually by the coulah (Jekri). They are also sometimes sold by the bag, weighing either 25 lb. or nearly 50 lb. in weight. The natives find old salt bags of different sizes very convenient for this purpose, more especially when the kernels are to be conveyed some distance to the nearest factory.

7b. At the beginning of 1915 hard oil was worth £32 per ton, and soft oil £36 10s. per ton, whereas at the beginning of 1918 soft oil was being sold at £36 5s. to £47 10s. per ton, whilst the official maximum price for unbleached palm oil is £44 per ton, and £50 per ton bleached.

7a and 11. Utility of the Oil Palm.—From the Oil Palm are obtained the following products: Palm oil, palm kernels, palm wine and yeast from the fermented palm wine. The shells of the nuts are used by blacksmiths, as they give out great heat. The growing head of the palm is used as a vegetable—palm cabbage. The stems of the leaves are useful as rafters or house posts in the Yoruba country, the leaves for making mats for roofing, and the midribs as brooms.

To obtain the wine, the tree is either tapped below the male inflorescence in Ibadan, Yoruba, etc., or when the tree is felled and the crown cut off. A calabash is placed so as to catch the outflowing sap, which is the palm wine.

The natives frizzle the kernels in an iron pot and obtain an oil which is used as an emollient for wounds and rubbing on bruises or sprains. It has a burnt smell. Only small quantities of kernels are used for this purpose in Nigeria.

Tapping is sometimes effected at the base of both inflorescences, but this is a more unusual method.

So far no use has been found for the wood, though it is uncommonly tough and very fibrous.

8. Amount of Produce Used, Eaten, and Amount Growing.—There is probably only 5 per cent., or at most 15 per cent., of the total possible trade done in this product from West Africa.

The amount of the oil used by the natives per annum is as follows:

Three gallons of oil per head per annum for food.

Half-gallon of oil per head per annum for illuminant in the Eastern Circle, according to Gilman, and half-gallon used mixed with camwood for rubbing on the skin per head per annum.

Allowing this amount for the total population of 8,000,000, we have a total of 32,000,000 gallons used locally per annum. This means the produce of at least 128,000,000 trees, taking into consideration the very poor or underbearing state of many of the trees. Some also are immature and not in full bearing when utilized. Even so, this represents only a part of the total possible crop, which might be 100,000,000 gallons and 500,000 tons of kernels. Although the above small percentage of the amount of trade done will eventually prove to be an exaggeration, partly owing to the cutting down of Oil Palms in making farms, there is nevertheless clear evidence that a great many more palm kernels especially could be obtained if there were an increased number of plants available for cracking the nuts in various parts of the country. Then, too, in those places where the trees stand too closely together, an increased yield would be obtained after they had been thinned out. Allowing for an area of about 7,000 square miles in the dry zone, where the Oil Palms are not found, and 12,000 square miles for mangrove swamps, rivers, roads, railways, town and village sites, also where there are no Oil Palms, and about 10,000 square miles of heavy evergreen and mixed deciduous forest areas where there are few or no Oil Palms, this leaves an area of about 50,000 square miles on which they are found growing. The density varies from over 200 per acre down to only one, or in isolated cases to one to ten acres. With the increased amount of the tapping of the Oil Palm, as well as cutting it down both to get the palm wine and for making farms for food as well as cocoa crops, there is a great danger of the total amount being reduced. Everywhere on the West Coast of Africa where other produce has been introduced, such as in the Congo and in the Gold Coast, the export of palm produce tends to fall very rapidly. Owing to the fact that such a large amount of palm oil is used for alimentary or other purposes locally, and a great deal is exported to the Northern Provinces, the export of palm kernels to Great Britain and Europe generally forms the better basis in calculating the amount of palm produce now actually produced in the country. The small number of kernels used for making an oil for local use is really quite a negligible quantity, and will no doubt almost die out when there are larger amounts of pomade and other skin emollients available for the natives to buy.

9. European Machinery for Extraction (Pericarping).—Mr. E. W. J. Trevor, of 87, Maida Vale, claims two machines for detaching and removing the pericarp of palm fruit with abrading, and has devised also a means by which the fruit is held in place and has along in line, an endless band or chain. It is not stated, however, if this is successful.

Another apparatus with knife-blades for decorticating the pericarp has been patented by Mr. H. Beckwith, of 2, Rumford Street, Liverpool. It is called the depericarping machine. Dr. Hupfeld’s oil process is carried out at Agu (Togo).

Haake, a Berlin firm, constructed a machine called the wet process. The fruit is heated with water and freed from the pulp in special machines. The pulp is allowed to drain, and then heated again and put under presses. The nuts are cracked in a large centrifugal machine, and the shell is separated by a drum-like sieve or by brine. With this process 100 lb. of fruit yield 15 lb. of oil and 14 lb. of kernels. Four or five tons of fruit can be treated daily by fifteen or twenty men. The natives only extract 7 per cent. of the pericarp oil. This oil contains over 30 per cent. of fatty acid and is only used for soaps.

The Government has set up kernel-cracking machines in various places in West Africa.

10. European Nut-cracking.—Several plants have been put up latterly to deal with the cracking of kernels by machinery.

One of the first of such factories was started at Benin River, Warri province, where the shells after the nuts had been obtained from them were used for firing the engines of the machinery. Another factory exists at Abonnemma, Owerri province, and yet another was started at Yenagoa in 1914. The natives seem very willing to bring in the nuts to be cracked, especially where the population is not large enough to both make the oil and crack the kernels, as in the Brass and Degema districts. Brine is often used for separating the kernels from the shell.

Some hand-machines have been brought out by Miller Brothers which crack the nuts, but both shell and kernels fall to the ground at the same time. A certain number of the kernels are broken in the process, but of recent years an improvement has been made in this respect. The cost of the hand-machine, amounting as it does to £30, is almost prohibitive for the native, unless a system of hire-purchase were to be adopted. Only a few of these machines (comparatively) have been sold to them.

Yield of Oil and Kernels from Whole Fruit by Machinery.—It has been variously estimated that out of a hundred tons of whole fruit the native obtains by his methods:

- 7 tons of oil worth (pre-war rates) £12 per ton = £84.

- 15 tons of kernels worth (pre-war rates) £6 per ton = £90.

Again, out of the whole fruit, the result of various investigations shows that the pericarp comprises 30 per cent., shell 56 per cent., the kernels 14 per cent., and that there is 50 per cent. of oil in the pericarp. It has also been estimated that out of a hundred tons of whole fruit, a maximum of 15 tons of oil and 14 tons of kernels can be obtained by machinery. These at the pre-war rates would be worth approximately £600 and £200—in all, £800. It has also been estimated that the crushing of the fruit, the various freights, the carriage by rail and ocean, cost of bags, shipping, landing charges, insurance and general expenses would amount to £4 per ton, or in all about £400. This leaves about £400 to pay for the fresh fruit and allow for a profit; thus, paying £1 per ton for the fresh fruit, there would still be £300 left for profit, or in the case of paying £2 per ton there would be £200 left. However, so far £1 per ton has proved too low a rate for the natives to accept, and in most places it has been refused. It is doubtful whether £2 per ton will attract them sufficiently to bring in the large bulk of farm produce which is available. From an average closely stocked Oil Palm area the fruit could not be collected at a cost of £1 per ton, and it is very doubtful if it could be done for £2 per ton. So far, it appears that the native working for himself in his own time will always do things at a cheaper rate than paid labour under European supervision. Further investigations will, however, prove what a high price can be paid for the fresh fruit at the factory and yet leave sufficient margin to make a profit on the extraction of the pericarp oil, and also of the cracking of the nuts. In this connection the crushing of the kernels is considered rather a separate economic problem, as several other market factors come in which do not apply to the case of the pericarp oil and the uncrushed kernels. The machinery for the crushing of the kernels on the whole is much more intricate, costly, and requires much more highly-trained European supervision.

10a. Percentage Oil and Kernels.—According to the investigations of the Imperial Institute, the composition of the fruit is as follows:

| Per cent.
Pericarp oil | 18
Fibre and moisture | 12
Shell and disk | 58
Kernel | 12
Cake for fattening hogs | 100

The kernel contains 46 to 53 per cent. of oil.

10b. Pericarp Palm Oil Analysis.—This is as follows:

Specific gravity 15/15° C. | 0·9209-0·9245
Melting-point | 24°-42·5° C.
Saponification value | 196·3-205·5
Iodine value | 53-57·4
Reichert-Meissl value | 0·86-1·87
Hehner value | 94·2-97

The solidifying-point of fatty acids varies from 35·8° to 46·4° C. usually 44·5° to 45° C.

(See also 7a, Uses; see also 12a.)

11. European Uses of Oil and Kernels, Palm Wine, Palm Cabbage, etc.—From 46 to 53 per cent. of oil is contained in the kernel.

Palm oil is used in Europe for making margarine, vegetable butters, chocolate and cooking fats. It makes a good butter-substitute. Palm oil is chiefly used for making soap and candles in England, according to Mr. Dennett’s paper. Tin plates are covered with palm oil to prevent oxidization. The leakage from the casks of oil on board ship is used for making metal polish. Railways use it for greasing axle-boxes on railway carriages.

11a. Nigerian Exports, Oil and Kernels.—The exports of palm kernels have been increasing almost continuously for years, owing to the gradual opening up of the country to trade, and also to the natives finding out the value of the kernel as an article of barter; nevertheless, more still could be obtained if hand-cracking machinery and more nut-cracking mills were introduced at suitable spots.

The following table shows the exports for the years 1909 to 1916 of

Palm Kernels.

1913 | 083,000 | 1,854,384 | £32 15s.

The following is quoted from Sect. 2, Mr. R. E. Dennett’s paper on British Trade in Nigeria. Valuable notes have been obtained from this paper with regard to the palm products.

Palm Kernel Exports to Germany.

About £5,000,000 worth went to Germany before the war.

Year. | Tons.
1911 | 262,680
1912 | 283,536
1913 | 241,961

12. Value of Oil and Kernels.—Since the war, the price of oil first went down £5 per ton and kernels £15 per ton up.

With kernels at £17 to £18 per ton, the oil is worth £36 15s. per ton.

Glycerine is worth £50 per ton, and pericarp oil contains about 8 per cent.

At the beginning of 1918 the price of palm kernels varied from £25 to £26 per ton, the latter figure being the official maximum for it.

12a. Description of Kernel Oil.—It is white or pale-yellow in colour, with a pleasant nutty taste. By suitable treatment kernel oil can be divided into liquid oil, olein, and solid palm-kernel oil, stearin. It is used for soap and candles, edible fats—such as palmine, margarine—cooking fats, vegetable butters and chocolate fats.

13. Import Ports in England and U.S.A. for Oil and Kernels.—Hull.—Congo kernels go to Hull by the Cie Congo du Belge line, run by Elder Dempster & Co. In the first six months of 1915, 20,821 tons of kernels were imported into Hull. In most statements on Hull the price of palm kernel cake is omitted, whilst those of linseed, Bombay cotton-seed, and Saga Bean are always quoted. Hull imported between 40,000 and 50,000 tons in 1915 (from January to November only, 31,723 tons); 200,000 tons were taken by Germany before, and hence are available now.

Bristol.—Bristol as a port is prepared, according to its seed-crushers, to try kernels, but they asked the Colonial Office for protection from Germany.

Liverpool.—For the first six months of 1915, 87,366 tons of palm kernels were imported into Liverpool, against 73,000 tons in 1914.

U.S.A.—In 1915, 4,000 tons of kernels were shipped direct to the States.

14. The Crushing of Palm Kernels in Africa and England.—The largest seed-crushing and oil-extracting centre in Great Britain is at Hull.

Most of the crushing used to be done in Harburg, near Hamburg, Germany, and only a little at Liverpool—some 70,000 tons out of 300,000 tons. Since the war began Hull and London (Erith) have taken up the crushing of kernels. Bristol and Manchester have both thought about it.

Crushing has been tried in Africa, but has not been very successful so far, the cost of the operations having proved too high. In the Congo, however, it is still being done.

The crushing plants in Nigeria are situated at Opoba and Apapa, near Lagos.

14a. Other Methods of Kernel Crushing—Solvents.—Commercially, kernels are heated with solvents or pressure is used to extract the oil. According to Mr. Dennett the first expression takes place at a temperature of 45° to 50° C., and the second at 55° to 60° C. The double pressing is necessary owing to the amount of fat in the oil. By solvents, all or only a part can be taken out of the kernels. If all is taken, then they are almost valueless as cake, owing to its lack of oil.

15. Palm-kernel Produce.—Palm-kernel cake used to contain 20 to 22 per cent. of fibre and 10 per cent. of oil, which went rancid, so was not liked here.

This was the main reason why palm-kernel cake was not used to any extent by farmers in England before the war.

15a. Yield of Oil, Kernels and Cake.—From 46 to 53 per cent. of palm-kernel oil is obtained from the kernels.

Roughly speaking, a ton of kernels yields half a ton of cake, according to Mr. R. E. Dennett.

According to the Bulletin of the Imperial Institute 1 ton of kernels yields 1,000 lb. of oil.

Palm-kernel Cake and Oil Exports.—Palm-kernel cake was exported to Denmark in September 1915-18, 863 bags.

15b. Analysis of Kernel Cake.—This, according to a recent analysis in the Field by Frank J. Lloyd, is:

Per
cent.

Fibre | 14·80
Mineral matters | 3·55
Nutrients— |
Oil | 6·17
Albuminoids | 16·12
Carbohydrates | 48·51
Water | 10·85
| 100·00

A further analysis shows:

| Per cent.
Oil | 05·5-10
Albuminoids | 15·8-18·5
Carbohydrates | 36-50

or per food unit it works out to £4 16s. per ton. Indigestible fibre reaches 10 per cent., or in older samples of ten years ago 28 per cent., which is far too high. As a unit it costs 1s. 4d., against 2s. 7d. for cotton-seed meal.

According to E. D. News the analysis is:

| Per cent.
Albuminous matters | 17-30
Fatty matter | 10-18
Gum, sugar and starch | 30-40

15c. Kernel Analysis.—According to the investigations the analysis showed:

Specific gravity at 90/15° C. | 00·873
Iodine value | 10·3-17·5
Saponification value | 242-255
Titer test | 20·0-25·5° C.
Hehner value | 91·1
Reichert-Meissl test | 5·0-6·8

16 and 17. Value of Palm-kernel Oil and Cake.—Palm-kernel cake is sold at 7s. per cwt., and only 10 per cent. of the food ration is given to cows or calves for the first time.

According to the Oil and Colours Journal, in September 1915 palm-kernel oil was worth £37 10s. per ton first hand, and £48 in March 1916. According to this journal it is the lowest priced of all the cakes. The price of the cake is £7 to £7 5s. per ton.

The cake is sold at £7 5s. free on rail per ton at Hull. At the beginning of 1918 it was worth £13 15s. per ton, but in Surrey it could not be obtained under £21 per ton.

Palm-kernel oil is worth about £40 per ton.

At the beginning of 1918, palm-kernel oil extracted by solvents was worth £51 per ton; crushed, £52 per ton; refined, £67 per ton—which were the official maximum prices.

17. Uses of Palm-kernel Cake.—Kernels worked by solvents make a more digestible meal—80 per cent. against 73 per cent. of crushed kernels, and containing 19 per cent. of protein and 2 per cent. of fat, against 18 per cent. of protein and 8 per cent. of fat for crushed kernels. It is used for feeding young pigs and milch cows in Germany.

18. Results of Feeding Experiments with Kernel Cake.—The weekly gain in live weight with kernel cake ration was 8 lb. at the West of Scotland Agricultural College. The cost worked out at 4½d. per lb., and 3 lb. of kernel cake gave better results than 4 lb. of bran.

At the East of Scotland College, a gain of 2·04 lb. per day was recorded, the cost being £6 6s. per ton.

Experiments conducted in Scotland showed that cattle increased 1·95 lb. per day with palm-kernel cake, against only 1·84 lb. with linseed cake. No difficulty was found in keeping the cake, and it did not go rancid.

The cattle fed on palm-nut cake were stated to look glossier, carry more bloom, and have a looser skin than those fed on cotton-seed cake. It is also claimed that the fat content of the milk is increased, though the amount of extra butter-fat produced per day cannot be demonstrated.

A mixture containing 3 lb. of palm-nut cake is recommended per day for milch cows, and one containing from ¼ lb. to ½ lb. for sheep and pigs.

Ten per cent. of the ration should be given to cows or cattle the first time. Only 2 lb. of cake per day is given to animals.

According to the Cambridge University Department of Agriculture the feeding value of palm-kernel cake for bullocks is practically the same as that of linseed cake.

The feeding experiments demonstrated that the palm-kernel cake gave equal results to linseed or cotton-seed cake, and paid better because of the lower price of palm-kernel cake for milch cows and cattle. It is recommended for pigs too. The cost of feeding for eighty-four days was 43s. 4d. for palm-kernel cake against 51s. 6d. for linseed, and a gain of 164·5 lb. in weight against 167 lb. flesh weight with linseed cake. Cattle do not take to it readily at first, but afterwards like it.

According to Wyndham R. Dunstan, palm-kernel cake costs 1s. 5½d. per food unit as compared to 2s. 4d. for hay, hay being £5 per ton.

According to Thomas Fawcett, L.M.R., A.S.E., it is a question of what is relatively cheaper. British farmers have always bought linseed cake at £10 10s. per ton, when beef was only 10d. to 1s. per lb. Relatively, it would be better to go in for more cows being fed with palm-kernel cake. He also states that kernels only came in irregular quantities.

The cake, according to Lancashire County experiments, must be given as part ration, as milk yield goes down with kernel cake alone.

18a. Palm-nut Meal: Experimental Results of Feeding.—In 1879, in Agricultural Chemistry, by Johnson and Cameron (2nd edition), palm-nut meal from England and the Continent is mentioned and recommended as the cheapest meal for cattle, especially calves. The Royal Agricultural Society of England in 1878 also published a pamphlet for the Paris Exhibition, in which a mixture including a large proportion of palm-nut meal is recommended, and the experience in feeding young animals is given, showing that it is far cheaper and that linseed cake is really very expensive. Fourteen beasts fed on linseed cake averaged at eighteen months old 13·5 lb. live weight the week, or only ¾ lb. less than the heaviest at the show, on less food, especially using palm-nut meal.

According to others, meal is not recommended owing to its going rancid and its indigestibility.

19. Manurial Value of Kernel Cake.—The manurial value of palm-kernel cake is £1 4s. for the ration as given per ton.

20. West African Shipping in Relation to Farm Produce.—Before the advent of the German line, the West Coast was at the mercy of the Shipping Combine, as it is now, freights being arranged accordingly.

Since the Government has fixed maximum freight rates, shippers now know the largest amount they will have to pay, but even so freights are extremely high, and with no outside competition are unlikely to be brought down very much.

21. Bibliography of the Oil Palm.—Monsieur Chevalier’s Les Végétaux Utiles de l’Afrique tropicale française, Fasc. VII (1e partie), “Documents sur le Palmier à Huile,” contains a great deal of valuable information on the subject of the Oil Palm. The Oil Palm, by J. H. Farquhar, summarizes the results of a year’s investigations as to the growth and yield of the Oil Palm in the Southern Provinces of Nigeria.

In the monograph Oil Seed and Feeding Cakes, issued by the Imperial Institute, a complete account is given of the new British palm-kernel industry.

CHAPTER XIII

THE FOREST IN RELATION TO AGRICULTURE

The intimate and very important connection between Agriculture and Forestry is not at all widely recognized, so it is desirable to bring out more fully exactly how the one reacts on the other: the value of forests from the climatic point of view to agriculture, the economic effects on it, as well as the population connected with it.

In all the older civilized countries, such as France, England and Russia, and the United States and Canada of the newer ones, definite and almost exactly fixed quantities of land are used for agricultural purposes on the one hand and for Forestry on the other.

In the Gambia, Sierra Leone, the Gold Coast and Nigeria, however, with the exception of about 1,500 square miles of forest reserves and certain native land planted with rubber or cocoa, all the land (even when covered with finest mahogany forests) is liable to be farmed for a time and then abandoned for another piece of forest-land under the system of shifting cultivation. In practice, this means that every year thousands of square miles of forest are ruthlessly cut down, in order that the land may be used for agricultural crops, for one, two, or at the most three years’ crops. In the drier parts of the countries named, through such forests as exist, grass-fires annually burn, and destroy many trees in order to provide poor grazing for herds of the nomads’ cattle.

It might be argued that in the comparatively damp and hot climate which attains in a great part of the Gambia, Sierra Leone, the Gold Coast and Nigeria, which are also to some extent still covered with forest, it would be most advantageous to clear as much land as possible. This, however, is a delusion resting on false impressions, notably that the countries named are so much covered with thick forest. In most places this so-called “forest” is in reality an almost worthless secondary growth, consisting chiefly of umbrella trees (Musanga Smithii), soft-wooded Hannoa, creepers, grass, with isolated half-burnt or decayed trees from the original forest. Again, too, this system of clearing new land is quite haphazard, so that, after the first crop has been taken off, the land may be found to be too poor to be planted again; the natives then abandon it. In some places, chiefly in the Benin and Oban districts, they even go so far as to put a “Ju-ju” on the land, which is in effect a notice to say that the land is of no use for a farm. However, this is usually forgotten in a generation, so that the same thing may happen again, only that insufficient time has elapsed for a proper forest to be grown, as the cutting of the original forest may have so altered the climatic factors of the locality that not only different species of trees but also grasses have come in, and choked nearly all the self-sown forest-tree seedlings. The main beneficial effects of the forest may be summarized as follows:

1. The rainfall of the locality is increased, according to the figures of the Indian rainfall stations. This may amount to as much as 16 to 28 per cent. increase on the annual rainfall.

Afforestation on the Russian steppes has shown that more rain now falls on the planted area than in former years.

In Western Canada it is generally said that its climate is altering, and a general increase of rain has been noticeable since plantations have been made on thousands of farms and what forests there were originally have been rigorously protected from annual fires.

2. The rainfall both above and in the ground is more regularly distributed.

First of all, nearly 23 per cent. of the rain which falls on the trees in a forest is re-evaporated into the air and does not reach the ground at all. This in itself increases the humidity of the atmosphere, tends to form clouds, and thus induces further rainfall. The clouds tend to protect the plants from excessive sun at what may be a critical period in the growing season. The extra humidity of the atmosphere does not necessitate the plants transpiring so much moisture as they would otherwise have to do, to keep them in growing condition. Compared to that in the open, only 22 per cent. of the amount of evaporation takes place in the forest, added to the fact that it occurs under the canopy of the trees, thus creating the more humid atmosphere which is so suitable, for instance, for the growth of cocoa and other such crops. In other words, we can take one hundred parts as the amount evaporated in the open, of which not a quarter is evaporated in the forest. Again, as we have seen, twice as much of the rainfall soaks into the ground in the forest as in the open, and owing to the tree-roots and general covering of the soil the water can only flow away gradually. On the other hand, in the open, if the ground is at all sloping, more than half of the rain which falls to the ground runs away immediately, or lies on the land, flooding it and making planting impossible.

Fig. 106.—Rest House Teak Plantation at Ndeh, showing rows of trees 9 feet apart and 4 feet between.

Fig. 107.—View between the lines of one-year-old Teak Plantation at Ndeh, in which trees were planted 4 feet apart.

To face p. 486.

The trees then act as a rainfall distributer and also as a rainfall regulator. The roots of the trees act like a sponge, absorbing a great deal of the rainwater besides preventing it from running away. It has been calculated that it takes nearly six months for the rainfall to come out in the springs of a forest. This also to some extent accounts for the saying that if the wells are full in October in the Temperate Zone, or at the end of March in the Tropical Zone, there will be sufficient water the whole year round. With a varied distribution of forests in the country, the above two effects are naturally felt on neighbouring agricultural land, and in many cases make possible the growing of certain crops, such as cocoa, Cola and rubber, which otherwise could not be attempted. An interesting example of this is seen in the way in which the natives of Ilobe, in Nigeria, have planted Cola trees just inside and on the edge of the Ilaro Forest Reserve boundary.

3. The forest protects the land against corrosion. In most countries, wherever the ground is sloping and bare the annual fall of rain washes away large masses of good soil as well as stones and other debris, in many cases destroying pasturage or agricultural land, and in any case silting up the rivers with sand-banks and bars, thus hindering navigation. It has often been said that, for its size, the Cross River carries in the rainy season much more material in suspension and rolled along its bed than many other African rivers. The main reason apparently for this fact is that several of its tributaries, such as the Mbu, the Fi, the Mfu and the Bago, rise at what are now partially grass-covered mountain slopes, but which no doubt were a short time ago covered with fine evergreen forests.

The immediate effect of clearing such slopes is that the water, to the extent of nearly 90 per cent., rushes unchecked down the mountain slope, gaining momentum with every mile and taking grass, soil and even whole mountain slopes (1,500 feet in height) along with it. On the other hand, if such slopes are covered with forest trees 25 per cent. of the rainfall is re-evaporated into the air before reaching the ground, 10 per cent. is evaporated from the ground into the air of the forest, and fully 65 per cent. soaks into the ground.

An instance of this last effect can be seen in the Cross River Divide from the Bambuto Mountains, on the Nigerian border. In a few places the native farmers understand this effect and make the terraces on which they plant parallel with the contour of the hill-side; however, this is insufficient when the whole mountain slope has been cleared of forest. Only a definite distribution of the land between forest and farm would prevent the undue corroding of hill-sides. The unrestricted rush of the rainwater off the hill-sides has yet a further effect on the lower ground of the country, in that it causes the streams and rivers to flood and overflow their banks. This, in turn, prevents huge acreages of land from being cultivated for many months in the year, and other large areas lower down from being cultivated at all.

Yet another effect is that a vast mass of water hurries down into the sea where it is not required, and where there is already plenty of evaporation; whereas the greater part of it might have been stored up in the forest to form perennial, almost unaltering springs, streams and rivers. Two interesting examples of this are seen in the slight, almost negligible rise in the Okwo and the Igbagon streams of the Benin province. Both of these rivers rise in thick forest, and thick forest is also found on their banks.

In a similar way, instead of the water of the rivers being used for irrigating land which is sandy and dry in the dry season, it rushes away into the ocean for nothing. The flooding of much of the land near the rivers also kills many large forest trees and causes a rank growth of shrubs, creepers and grass, which form the breeding-places for tsetse and other harmful flies. It is rare to find any infected tsetse flies near a clear perennial stream in the forest.

4. The forest improves the soil of a locality, whether in the primeval or the planted forest. The trees stand at least eighty years, and sometimes for several hundred, on the same land, before being cut down. During this period the tree roots with their root-hairs are penetrating far and wide into the soil, subsoil, and even underlying rock, gradually causing the two latter to weather into finer and better constituent parts. For instance, nothing appears so solid as a mountain of granite; nevertheless, at the base and to the lee-side of each boulder, more especially if there is any tree-growth there, a beautiful little bed or pocket of blackish soil will be found. Then, again, besides this weathering of the subsoil and rock, the tree leaves, even from evergreen trees, fall down, gradually decay, and form a thick layer of humus. This in itself forms an almost ideal seed-bed. At the edge of forests this humus is washed out on to the agricultural lands and thus enriches them; furthermore, dry leaves are blown out of the edge of the forest on to neighbouring agricultural land, become dug in, or drawn into the land by insects, and so tend to enrich it. In many civilized countries a regular business is done in taking litter and leaf-mould out of the forest to neighbouring garden and farm lands.

It is a well-known fact that when a forest is cut down after some hundreds of years many plants appear in the clearing which did not exist in the forest before, or, in fact, were not known in that locality, the seeds having lain dormant during the whole period of time. This clearly shows that the forest soil is an ideal medium for preserving seeds, and that it improves rather than deteriorates, which is the case with bare land. An instance of this from the Tropics is seen in the way in which the Corkwood or Umbrella Tree (Musanga Smithii) comes up after the mahogany and evergreen forest has been cleared. No Musanga trees are usually found in the primeval forest. A parallel example from Europe is seen in the way in which Atropa belladonna almost invariably appears when a beech forest is cut down.

Planting trees and thus forming a forest, though expensive, is another way of clearly proving the beneficial effect of the forest, or ameliorating the condition and plant-food content of the soil. On the comparatively worn-out and poor soil near Ibadan a firewood plantation was started some years ago; now already, in the shade of the Ayin, Anogeissus leiocarpus and Cassia Siamea trees, the fallen leaves have decayed and formed a layer of humus, killing out the lalang grass at the same time. Needless to say, it is a very expensive method to wait until the forest has been destroyed, the soil impoverished, and trees again planted, before an improvement in the soil conditions can be expected.

5. Individual trees, and thus trees in the aggregate, viz. forests, take less mineral matter out of the soil than agricultural crops covering a similar area. It has been calculated that the trees on an acre of land only take one-twelfth of the amount of mineral matter out of the ground which is required by an agricultural crop on the same area. It follows from this that trees, and in the same way forests, may be left standing upon or be grown on land which is nearly or absolutely worthless from an agricultural point of view. In the more civilized countries this is seen, for instance, in the way in which the mountain ranges of Germany have remained covered with forest and the sandy Landes district of France has been planted with forests of pine. In Canada, the Spruce Hills Reserve, near the Canadian Pacific Railway in Manitoba, is another example of the setting aside of poor, almost worthless agricultural land as a permanent forest area. In Nigeria, the Oban Forest Reserve and the forest-covered hills of Olokemeji are further examples of the practice of this principle.

Generally speaking, in fact, in most civilized countries there are really three types of land, viz.:

(a) Absolute farm-land, which comprises the very richest and best land of the country, in which forests should only be allowed to stand, as an exception.

(b) Relative forest-land, comprising land which can be used permanently for agriculture, but requiring a great deal to be spent on improvements or manures to make it suitable for the purposes, but which in its natural state carries a heavy stand of timber, could be used for forests indefinitely.

(c) Absolute forest-land, comprising land which, owing either to its elevation, aspect, soil or position, cannot be used for the permanent cultivation, or in some cases even the temporary cultivation, of crops.

6. The forest protects agricultural land against storms and insect pests. In many places, owing to very strong winds, certain crops cannot be grown. For instance, it is said bananas cannot be grown at Zaria owing to the prevalent strong winds. In the Chang district of the Cameroons the natives only plant plantains near their houses or behind the very high fences or hedges which mark off one man’s compound from another. Apparently this is done in order to protect the plants from the wind, which otherwise tears their large leaves into shreds and prevents their proper growth.

Some years ago, in the Ibadan district, a fierce tornado cut a path about 100 feet wide and nearly a mile long through a forest, but the agricultural land beyond was untouched. It goes without saying that had all the land been under crops in this locality most of them would have been destroyed, whereas the forest took the brunt of the storm, and the force of the wind outside was thus weakened and comparatively harmless.

7. The forest protects the soil and its physical properties. In the open it is noticeable that the native rarely clears the land properly, many stumps both of forest trees and shrubs being usually allowed to remain standing. It is true some of the shoots from the stumps are left on purpose to be used as supports for the yam tendrils or other crops which may be grown. Nevertheless, it is a fact that the native always says that the land must not be absolutely cleared of all stumps and roots or it will be useless for the growing of crops. Then, again, the native speaks of a piece of ground as being “spoilt,” and that he cannot stay there any longer. As an example of this, in the Oban district, the people of Ekong left the village site because they said the ground was too stony and was no good, and they went right away into the forest. On an examination of the land being made, it was found that where they had cleared the forest and farmed for a few years all the humus, tilth and other soil had been washed away, with the result that boulders as well as the underlying rock had to some extent come to view. Needless to say no attempt had been made at farming under a rotation of crops, nor had any manure, green or otherwise, been applied to the soil. On the other hand, in the forest the soil is not washed away, the aeration of it is almost perfect, the mineral content is always high, and it usually has considerable depth, even where there are rock outcrops, for these become covered with dead leaves or humus, which in their turn help to weather the rock and thus make more soil.

8. The forest tends to regulate the temperature, almost preventing extremes of heat and cold. Accurate measurements taken over a period of forty years have established the fact that in the warmest season the temperature of the forest is 5° to 10° lower, according to species (altitude taken to be the same), than the air in the open over agricultural land. In a similar way, in the coldest season of the year the temperature of the forest is 5° to 10° higher than in the open over agricultural land. Most readers will have experienced the feeling of freshness and coolness in passing through the forest zone near Olokemeji on the Nigerian Railway, or, if on leave in England, in passing through the New Forest on the Bournemouth road. This is only the effect which is expressed in this difference of temperature: as with other effects, so this one affects the neighbouring lands near the forest. Even a dry wind on reaching a forest must take up some moisture, and thus be less dry when it reaches agricultural land farther on. It can often be seen how the grain in the drier parts of the country planted near the edge of a forest sprouts up sooner than that right in the open. Again, certain crops, such as cacao-yams, cocoa, and Cola trees thrive best amongst trees. Without the forests the Cola plantations of the Ilesha district would cease to exist, or at any rate bear very small crops.

9. The forest increases the humidity of the air. According to accurate measurements taken over a period of forty years, it has been proved that the forest increases the humidity of the air up to 10 per cent. No doubt in many of the Southern parts of Nigeria and the Gold Coast, people travelling in the forests have often thought that there was far too much moisture, not only coming from above and below, but also in the air around them. However, this should not blind us to the fact that further up country this greater humidity of the air of the forest is spread over the adjacent lands, and thus makes possible the growth of agricultural crops, such as cocoa, Cola, yams, and cacao-yams, which would not otherwise be possible. This greater humidity also tends to induce local minor rainstorms, which in their turn benefit the adjacent agricultural land. This greater humidity of the air also tends to prevent the excessive drying in the dry season of the land situated very near, and taken in conjunction with the other factors, such as the regulating of the temperature and the rainfall, makes it possible to put in crops earlier and almost ensures their growing successfully.

10. The forests prevent the spread of insect and fungoid pests. So often we read that the crops in South Africa or the Argentine have been destroyed by locusts, and on the Gold Coast we read that various pests are destroying cocoa-trees in large numbers. Here, again, a forest or a belt of forests with large numbers of different species of trees interpose a living barrier of green leaf food or woody tissue which these pests may attack, owing to the diversity of the species of trees. Most pests only find a few trees on which they can thrive or reproduce themselves; thus on reaching the forest the scourge tends to lessen, or even die out. Even in the worst case of large hordes of locusts, it is cheaper to allow them into a forest, perhaps sacrificing it, rather than they should spread further and further over agricultural lands.

Having shown that it is necessary in a new and comparatively unsettled country to preserve a certain proportion of the forests, it remains to be considered what proportion is desirable and necessary to fulfil the conditions outlined before and give free play to all the beneficial effects of the forests.

Taking the proportion of permanent forest to other land in the more civilized countries, we get the following ratios:—

| Forest per cent.
Finland | 80
Russia in Europe | 42
Austria | 33
Hungary | 29
Germany | 26
France | 16
Sweden | 42
Switzerland | 19
Norway | 25
U.S.A. | 10
India | 38

Special note should be made of the fact that in all these countries the agricultural development has gone hand in hand with the preservation of the forest, and especially with no detriment to the development of agriculture in any direction in which it seemed desirable. Russia has, for instance, enormous exports of timber and enormous exports of wheat. Austria-Hungary had before the war considerable exports of hardwood timber, such as oak, as well as grain, both wheat and other kinds. Judging by the experience gained in Germany with its hundred and seventy years of forestry practice, a proportion of 25 to 33 per cent. of the land area of any country can reasonably be retained under forest, or afforested if bare. Such a proportion allows sufficient timber trees to be grown to cover the large quantities of wood used in industrial development and also a considerable surplus for export to other countries.

Turning specifically to the West African Colonies, it would mean, out of a total land area of 4,500 square miles, that in the Gambia, for instance, an area of between 1,100 and 1,500 square miles should be permanently set aside as Forest Reserves or Forest Reserve Afforestation Areas. In the latter case, when all were planted up they would gradually become forests.

In Sierra Leone, with a total land area of 34,000 square miles, the area would vary from 8,500 to 11,000 square miles.

In the Gold Coast, out of a total land area of 80,000 square miles, the permanent forest area would vary between 20,000 and 26,000 square miles.

In the Southern Provinces of Nigeria, with a total area of 79,000 square miles, the permanent forest area would reach between 19,000 and 26,000 square miles.

In the Northern Provinces of Nigeria, out of a total area of 250,000 square miles, the permanent forest area, including the afforestation areas, would reach between 62,000 and 83,000 square miles.

Large though these forest or afforestation areas appear to be, it can, however, be shown that most of them do not at all trench on existing farm-land. First of all, in Nigeria, taking the protective forests, comprising all those lands or forests situated in most inaccessible places on mountain ranges and hill-sides and the sources of streams, they cannot be said to be desirable localities for extending farming operations. Typical instances of this kind of land are seen in the Boji Hills (Ogoja province), and on the rocky hills near the Cross River in the Afikpo district (Owerri province). In Sierra Leone the peninsular mountain forests and the hills near Kennema are similar typical examples of this type of land or forest.

At the other extreme we have the dry-zone or desert formation, with its sandy soil or bare rock outcrops. In either region, in order to make agriculture possible and permanently profitable, afforestation areas are most necessary. Near the sea, especially in Nigeria and to some extent in Sierra Leone, there are the mangrove forests standing on land which is never used for agricultural purposes. In Nigeria alone these comprise several thousand square miles of land. Again, in Nigeria there are the freshwater swamp forests, either near rivers or in other localities. Although such lands produce quite a profitable amount of timber from many excellent species of trees, no farms have ever been made in such areas.

In other parts of the country, often comparatively level, there are variations in the strata and soil formation, such as that of the laterite formation. Over wide areas most of these lateritic soils are nearly useless for permanent agricultural crops, so at any rate it would certainly pay better in the long run if it were permanently covered with forest. In a similar manner all forests found growing on or near rock outcrops or otherwise stony formations, such as old gravel beds formed by rivers, would be treated in the same way. One or two agricultural crops may be raised on such land, but all the soil is soon washed away in the rainy season each year, so that little is left after a short time except boulders and stones. Many typical instances of this kind of formation are found in the Ibadan and Oyo districts of the Oyo province. In other parts of the country, where practically all the land is covered with some sort of forest (either high forest, secondary growth or scrub), the same proportion as before, viz. 25 to 33 per cent., should be set aside in convenient blocks, well distributed over the area, as permanent forests (so-called Forest Reserves).

Strange as it may sound, there is comparatively little, at the most an area estimated at 7,000 square miles, of real high forest left in the Southern Provinces of Nigeria. As is well known, the natives have a special name for this type of forest; amongst the Efiks it is called Ekai, the Yorubas term it Igbo, and the Benin people Egbo. Considering the size of these last remnants of the real high forest, agriculture cannot justly claim the right to clear and farm even this area when so much (estimated at 28,000 square miles), apart from the area already mentioned, has been cleared during the last fourteen years. In the above estimate, areas even of 500 square miles for roadways and railways, 1,000 square miles for town, village and factory sites, and 2,500 square miles for inland waterways were allowed for when computing the whole area of forest land.

At the present time in Nigeria, with the exception of certain specified trees, and less so in the Gold Coast, Sierra Leone and the Gambia, there is nothing to hinder a native from cutting down any forest he pleases for making a temporary farm. In fact, the difference between farming as practised in civilized countries and in these tropical West African Colonies is that the former partakes of a permanent cultivation of the same land every year, whereas the latter is shifting cultivation of a different piece of land almost every year. At the most, the Yoruba returns to the land in five or seven years, and the native of Benin after ten or twelve years.

Another point which bears on this question is really the comparatively small amount of land which a native actually farms every year. For instance, an energetic Yoruba farmer will make 2,000 yam heaps a year, which, allowing for the distance of 6 feet between each heap, amounts to 1·6 acres per year. This also includes the help which he may receive from his family.

Out of a total population of 8,000,000, at the most 2,000,000 are actually men who make farms. It follows, then, that some 2,560,000 acres, or 4,000 square miles, are cleared and planted each year. Now, allowing sufficient land for the native to be able to return to the original piece cleared after seven years, the total amount of land necessary for the existing farming population would be 28,000 square miles, or rather more than a third of the total area of the country. Even after allowing 19,000 or 26,000 square miles of forest in the country, there would still remain nearly a third, or 25,000 square miles, for the future development of agriculture and the natural increase of the population. It should be especially noted that it is under a system of shifting cultivation that this 28,000 square miles is required. No doubt under permanent cultivation less would be necessary. Quite apart, however, from this consideration, owing to the greater heat, moisture and humidity in the Tropics generally, and in the Southern Provinces of Nigeria particularly, agricultural crops grow much more rapidly and are much more prolific than in the more temperate zones, even without manures. Yet in another way there is not such an enormous demand on the amount of land required per unit of population, in that over an area of fully 30,000 square miles it is possible to raise two crops a year on the same land, and over roughly an area of 10,000 square miles of the country it is possible to raise three crops per year (in each case under a rotation of crops). In this manner less land is required per person than in a temperate climate in order to grow food either for local consumption or for export.

So far we have dealt with shifting cultivation. However, in most civilized countries, sooner or later a system of permanent cultivation is started instead of shifting farms. In England this was begun at a time in which the population was less dense to the square mile than it is now in the Southern Provinces of Nigeria (average 101 persons per square mile). In Germany the density of population is 323 persons per square mile, yet they had (before the war) 25 per cent. of the land area of their country covered with permanent forests. If it were possible to start permanent cultivation with a rotation of crops in England when the population was less dense than in the Southern Provinces of Nigeria, it should be feasible in Nigeria now. Again, if it is found possible for Germany to retain 25 per cent. of the land area under permanent forest crops, with a density of population three times greater than that of Nigeria, at the same time maintaining a prosperous system of permanent agricultural cultivation, it should also be much easier to have a similar proportion of permanent agricultural cultivation in the Southern Provinces of Nigeria; at the same time, taking into consideration the more favourable climatic factors, it should be possible not only to grow sufficient foodstuffs for local use, but also to grow sufficient to develop into a large export trade for ground nuts, maize and beans, besides cocoa and rubber.

CHAPTER XIV

BIBLIOGRAPHY OF WEST AFRICAN FORESTS

1. Historical.

One of the first books was Forestry in West Africa, by Sir Alfred Maloney, a former Governor of Lagos, which was published in 1887. This is a most interesting and readable book, and, for the time it was written, gives a very good account of many of the forest trees. It is also much to Sir A. Maloney’s credit that teak, Tectona grandis, was introduced into Nigeria at that time.

In The Journal of an Expedition to Explore the Course and Termination of the Niger, by Richard and John Lander, only very vague descriptions of the forests are given, and it is therefore not of much value from the Forestry point of view, though it is a most entertaining description of the people and their doings at that time.

2. Botanical.

From 1868 onwards, Flora of Tropical Africa appeared; so far eight volumes have been published. This work was planned by the late Sir William J. Hooker and edited first of all by Daniel Oliver, and subsequently by Sir W. T. Thistleton-Dyer, K.C.M.G., C.I.E., and now by Lieut.-Colonel D. Prain, the Director of the Royal Botanic Gardens, Kew. It is, of course, very scientific, accurate and botanical, but has very dry descriptions of many of the African trees and plants and no illustrations are contained in these octavo volumes. What also makes it harder to use this Flora is the fact that since 1868 many new plants have been named, and some of the names of the old plants have been altered. A most useful chapter on Elementary Botany is contained at the beginning of Vol. I. This is to some extent also a glossary of botanical terms, but of course it cannot take the place of A Glossary of Botanic Terms, by D. G. Jackson, 1905.

In many ways a much more useful book to the forester is Engler’s Monographien der Pflanzenfamilien, of which eight volumes have appeared:

I. | Moraceæ, excluding Ficus.
II. | Melastomaceaæ.
III. | Combretaceæ Combretum.
IV. | Combretaceæ, excluding Combretum.
V. | Sterculiaceæ.
VI. | Anonaceæ.
VII. | Strophanthus.
VIII. | Sapotaceæ.

The full-page black-and-white drawings of the various plants are very valuable, and as they are all done on the same system, comparison both with the plants and with other books is not very difficult. The expense of these volumes is not excessive, considering the very large number of illustrations and the authority of the text. It is a pity that this series has for the time being come to an end.

In Engler’s Pflanzenfamilien, of course, a very complete account of all plants is given, and the additions to it made almost monthly make it quite possible to find out the latest-named additions to the plant-world. The only disadvantage to these volumes is their number, size, and lack of illustrations.

Fig. 108.—Shinglewood (Terminalia scutifera), 12 feet in girth, standing in the Ikrigon Forest Reserve, Eastern Circle.

Fig. 109.—Iroko (Chlorophora excelsa), 15 feet in girth, standing in Ikrigon Forest Reserve.

Fig. 110.—Mahogany (Khaya Senegalensis) standing at the edge of Ikrigon Forest Reserve, showing base of trunk with old bark wounds already healed over.

To face p. 496.

In a similar, though in a less complete way The Kew Bulletin gives the latest list of plants identified at Kew, amongst which are usually some from Nigeria, and occasionally special bulletins appear on the plants from Nigeria—as, for instance, Bulletin of Miscellaneous Information, Additional Series No. 9; The Useful Plants of Nigeria, Part I, 1908, Part II, Additional Series No. 10, 1912, Part III.

The Bulletin of the Imperial Institute, edited by Sir W. Dunstan, which appears quarterly, always contains the most recent information with regard to tropical products, including those of the forest. In recent years, too, much more has appeared on the subject of the timber, gum and oil-seed resources of Nigeria.

Die Blütenpflanzen Afrikas, by Franz Thonner, 1908, arranged as it is in the form of a key, is most useful in identifying many of the plants and trees. The black-and-white illustrations add immensely to its value. Additions and corrections to this have also been made in Die Blütenpflanzen Afrikas, 1913. The last edition is in English, and entitled The Flowering Plants of Africa.

Among more recent books is a Catalogue of Plants collected by Mr. and Mrs. Talbot in the Oban district, South Nigeria, identified by A. B. Rendle, M.A., D.Sc., F.R.S., and others, and brought out by the British Museum in 1913. In this book the flora of Oban is specially dealt with, and clearly shows the difference between it and the rest of the flora and silva of Nigeria. Although this is mainly a description of newly discovered plants, the black-and-white illustrations by Mrs. Talbot show most accurately their salient features.

Notes on Nigerian Trees and Plants, by E. W. Foster, late Senior Conservator of Forests, contains accurate descriptions of the most useful trees, and the native names from the Yoruba country will be most useful to anyone working timber in that part of Nigeria.

The Agricultural and Forest Products of British West Africa, by G. C. Dudgeon, Director-General of Agriculture in Egypt, 1911, gives a short description of the main forest and agricultural products of the country, which is more useful to the trader than the forester or timber merchant. The illustrations showing the making of palm oil and other country products are very interesting, but Fig. 21, p. 112, supposed to be of an Iroko tree, is in reality that of Terminalia superba.

For reference purposes Dr. Adolf Engler’s Syllabus der Pflanzenfamilien, 1904, which takes special account of the medicinal and useful plants, is most valuable.

For a proper introduction to Botany, Strasburger’s Text Book of Botany is hard to beat.

Kulturgewächse der Deutschen Kolonien, by R. Sadebeck, 1899, gives a very good account of most of the useful West African forest products; the very clear illustrations add immensely to its value, although the book is now somewhat out of date.

3. Timbers.

In The Timbers of Commerce and their Identification, by Herbert Stone, F.L.S., F.R.C.I., 1904, a few of the West African timber trees are mentioned, but only very cursorily, with but few illustrations.

In Timber, by J. R. Baterden, A.M.I.C., a few of the West African timber trees are described, and a few photographs show how the timber is worked. Their inclusion amongst the South African timbers does not exactly enhance their value or give a true view of their place in the economy of the timber trade.

Wood, by G. S. Boulger, gives an excellent system for classifying woods by using all their various characteristics, such as taste, smell, hardness, structure of the timber, and the various pith rays and other peculiarities. A very complete list of all the various timbers used in commerce is given, together with the various synonyms of each, and the botanical names of each so far as they are known. The uses of the timber and the supplies of each country are given, and in this way it is a most important book of reference for any Forest Officer.

4. Forestry Generally.

In Sylviculture in the Tropics, by A. F. Broun, Director of Woods and Forests, Soudan, 1912, some references are made to West African trees. Some very typical photographs of forest vegetation in various parts of the Tropics are very useful, and demonstrate several forest theories far better than pages of words.

A Dictionary of the World’s Commercial Products, by J. A. Slater, B.A., LL.B., 1907, is very useful for looking up the lesser known forest products. The descriptions have to be used with discrimination, as some of them are rather cursory and no authorities for botanical names are given.

Gold Coast Report of Forests, by Mr. H. N. Thompson, Chief Conservator of Forests, South Nigeria, 1910, is the authoritative work on the Forestry problems of the Gold Coast. Full descriptions of the chief forests are given, together with the important plants and trees found in each. The laws of South Nigeria as modified to suit Gold Coast conditions are also quoted. Forest policy as suitable for this country is given; the different types of forest and their relation to the climatic formations are also mentioned at length. A suitable establishment carrying out these suggestions is laid down. The black-and-white drawings which illustrate this book, especially those of mahogany, are invaluable to either the Forestry student or the timber merchant.

The Oil Palm and its Varieties, by J. H. J. Farquhar, Conservator of Forests, Nigeria, is an interesting and useful preliminary monograph on that most valuable tree. It gives a summary of all the information of the Forest Department on that subject up to that date.

List of Trees, Shrubs and Climbers of the Gold Coast, Ashantee, and North Territories, T. F. Chipp, B.Sc., F.L.S.; Der Tropenwirt, by Dr. S. Loskin, Hinstorff’sche Verlagsbuchhandlung, Wismar i. U., 1913; The Principal Forest Trees, by H. N. Whitford, Ph.D., Bulletin No. 10, Manila Bureau of Printing, 1911, are three useful books.

The Kew Bulletin and the Journal of the Imperial Institute always contain most valuable notes on the botanical and technical qualities of the various African trees and plants.

The Indian Forester, which appears monthly, is a most necessary periodical for every Forest Office or Timber Camp, containing as it does not only original articles on sylvicultural and other forest problems, but also much information on the uses of timbers, similar kinds of which are found here, and thus gives one an indication in what direction to exploit new timbers.

In the Guiana Forest, by Jas. Rodway, is a very readable book on the tropical forest scenery found in Demarara. It is, of course, written in very popular style, but gives one a very good introduction to the tropical forest, showing both by beautiful descriptions and good illustrations what one should observe in these forests. Much tropical scenery is very similar, and therefore, though this book deals with British Guiana, much of it is applicable to West African forests.

Forestry, by Dr. Adam Schwappach, gives a short, concise account of what is included under the term Forestry in Europe. One obtains a clear view of the divisions under which this subject is treated.

The Trees, Shrubs, Herbs and Climbers of Sierra Leone, by C. E. Lane Poole, Government of Sierra Leone, is the most important collection of notes yet issued on this subject. It should prove of greatest use to Forest Officers, and to all others interested in the forests and afforestation.

Much useful information has been obtained from the annual Reports on the administration of the Forest Department from the years 1906 to 1913, more especially from that of 1906, which practically summarized the results of the Department’s work up to that date. Data on Togo are contained in the report of the afforestation of Togo with teak and other African timber trees. This was the result of a long tour in that country made by the author in 1911. From Sierra Leone much valuable knowledge was acquired as a result of a five months’ tour made in 1908-9, and this was embodied in a report which appeared in 1909. Very useful information is contained in the reports by the Conservator of Forests there, which have appeared since. A most extensive account of the forest trees and plants, including the Oil Palm, is given in Les Végétaux utiles de l’Afrique tropicale française, by M. Chevalier, Parts I and II, 1909, 1910 (A. Challamel), chiefly in connection with the Ivory Coast.

In the Notizblatt of the Berlin Botanical Station are some useful notes on Die Nutz Holzer der Kamerun, 1909. Also in the pamphlets Die Nutz Holzer Togos, Parts I and II. In this manner it is possible to make a comparative study of the timber trees found in the different parts of West Africa. The addition of the native names in most cases is also very valuable.

*** END OF THE PROJECT GUTENBERG EBOOK WEST AFRICAN FORESTS AND FORESTRY ***

Updated editions will replace the previous one—the old editions will be renamed.

Creating the works from print editions not protected by U.S. copyright law means that no one owns a United States copyright in these works, so the Foundation (and you!) can copy and distribute it in the United States without permission and without paying copyright royalties. Special rules, set forth in the General Terms of Use part of this license, apply to copying and distributing Project Gutenberg™ electronic works to protect the PROJECT GUTENBERG™ concept and trademark. Project Gutenberg is a registered trademark, and may not be used if you charge for an eBook, except by following the terms of the trademark license, including paying royalties for use of the Project Gutenberg trademark. If you do not charge anything for copies of this eBook, complying with the trademark license is very easy. You may use this eBook for nearly any purpose such as creation of derivative works, reports, performances and research. Project Gutenberg eBooks may be modified and printed and given away—you may do practically ANYTHING in the United States with eBooks not protected by U.S. copyright law. Redistribution is subject to the trademark license, especially commercial redistribution.

START: FULL LICENSE

THE FULL PROJECT GUTENBERG™ LICENSE

PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK

To protect the Project Gutenberg™ mission of promoting the free distribution of electronic works, by using or distributing this work (or any other work associated in any way with the phrase “Project Gutenberg”), you agree to comply with all the terms of the Full Project Gutenberg License available with this file or online at www.gutenberg.org/license.

Section 1. General Terms of Use and Redistributing Project Gutenberg electronic works

1.A. By reading or using any part of this Project Gutenberg electronic work, you indicate that you have read, understand, agree to and accept all the terms of this license and intellectual property (trademark/copyright) agreement. If you do not agree to abide by all the terms of this agreement, you must cease using and return or destroy all copies of Project Gutenberg electronic works in your possession. If you paid a fee for obtaining a copy of or access to a Project Gutenberg electronic work and you do not agree to be bound by the terms of this agreement, you may obtain a refund from the person or entity to whom you paid the fee as set forth in paragraph 1.E.8.

1.B. “Project Gutenberg” is a registered trademark. It may only be used on or associated in any way with an electronic work by people who agree to be bound by the terms of this agreement. There are a few things that you can do with most Project Gutenberg electronic works even without complying with the full terms of this agreement. See paragraph 1.C below. There are a lot of things you can do with Project Gutenberg electronic works if you follow the terms of this agreement and help preserve free future access to Project Gutenberg electronic works. See paragraph 1.E below.

1.C. The Project Gutenberg Literary Archive Foundation (“the Foundation” or PGLAF), owns a compilation copyright in the collection of Project Gutenberg electronic works. Nearly all the individual works in the collection are in the public domain in the United States. If an individual work is unprotected by copyright law in the United States and you are located in the United States, we do not claim a right to prevent you from copying, distributing, performing, displaying or creating derivative works based on the work as long as all references to Project Gutenberg are removed. Of course, we hope that you will support the Project Gutenberg mission of promoting free access to electronic works by freely sharing Project Gutenberg works in compliance with the terms of this agreement for keeping the Project Gutenberg name associated with the work. You can easily comply with the terms of this agreement by keeping this work in the same format with its attached full Project Gutenberg License when you share it without charge with others.

1.D. The copyright laws of the place where you are located also govern what you can do with this work. Copyright laws in most countries are in a constant state of change. If you are outside the United States, check the laws of your country in addition to the terms of this agreement before downloading, copying, displaying, performing, distributing or creating derivative works based on this work or any other Project Gutenberg work. The Foundation makes no representations concerning the copyright status of any work in any country other than the United States.

1.E. Unless you have removed all references to Project Gutenberg:

1.E.1. The following sentence, with active links to, or other immediate access to, the full Project Gutenberg License must appear prominently whenever any copy of a Project Gutenberg work (any work on which the phrase “Project Gutenberg” appears, or with which the phrase “Project Gutenberg” is associated) is accessed, displayed, performed, viewed, copied or distributed:

This eBook is for the use of anyone anywhere in the United States and most other parts of the world at no cost and with almost no restrictions whatsoever. You may copy it, give it away or re-use it under the terms of the Project Gutenberg™ License included with this eBook or online at www.gutenberg.org. If you are not located in the United States, you will have to check the laws of the country where you are located before using this eBook.

1.E.2. If an individual Project Gutenberg electronic work is derived from texts not protected by U.S. copyright law (does not contain a notice indicating that it is posted with permission of the copyright holder), the work can be copied and distributed to anyone in the United States without paying any fees or charges. If you are redistributing or providing access to a work with the phrase “Project Gutenberg” associated with or appearing on the work, you must comply either with the requirements of paragraphs 1.E.1 through 1.E.7 or obtain permission for the use of the work and the Project Gutenberg trademark as set forth in paragraphs 1.E.8 or 1.E.9.

1.E.3. If an individual Project Gutenberg electronic work is posted with the permission of the copyright holder, your use and distribution must comply with both paragraphs 1.E.1 through 1.E.7 and any additional terms imposed by the copyright holder. Additional terms will be linked to the Project Gutenberg License for all works posted with the permission of the copyright holder found at the beginning of this work.

1.E.4. Do not unlink or detach or remove the full Project Gutenberg License terms from this work, or any files containing a part of this work or any other work associated with Project Gutenberg.

1.E.5. Do not copy, display, perform, distribute or redistribute this electronic work, or any part of this electronic work, without prominently displaying the sentence set forth in paragraph 1.E.1 with active links or immediate access to the full terms of the Project Gutenberg License.

1.E.6. You may convert to and distribute this work in any binary, compressed, marked up, nonproprietary or proprietary form, including any word processing or hypertext form. However, if you provide access to or distribute copies of a Project Gutenberg work in a format other than “Plain Vanilla ASCII” or other format used in the official version posted on the official Project Gutenberg website (www.gutenberg.org), you must, at no additional cost, fee or expense to the user, provide a copy, a means of exporting a copy, or a means of obtaining a copy upon request, of the work in its original “Plain Vanilla ASCII” or other form. Any alternate format must include the full Project Gutenberg License as specified in paragraph 1.E.1.

1.E.7. Do not charge a fee for access to, viewing, displaying, performing, copying or distributing any Project Gutenberg works unless you comply with paragraph 1.E.8 or 1.E.9.

1.E.8. You may charge a reasonable fee for copies of or providing access to or distributing Project Gutenberg electronic works provided that:

- • You pay a royalty fee of 20% of the gross profits you derive from the use of Project Gutenberg works calculated using the method you already use to calculate your applicable taxes. The fee is owed to the owner of the Project Gutenberg trademark, but he has agreed to donate royalties under this paragraph to the Project Gutenberg Literary Archive Foundation. Royalty payments must be paid within 60 days following each date on which you prepare (or are legally required to prepare) your periodic tax returns. Royalty payments should be clearly marked as such and sent to the Project Gutenberg Literary Archive Foundation at the address specified in Section 4, “Information about donations to the Project Gutenberg Literary Archive Foundation.”

- • You provide a full refund of any money paid by a user who notifies you in writing (or by e-mail) within 30 days of receipt that s/he does not agree to the terms of the full Project Gutenberg™ License. You must require such a user to return or destroy all copies of the works possessed in a physical medium and discontinue all use of and all access to other copies of Project Gutenberg™ works.

- • You provide, in accordance with paragraph 1.F.3, a full refund of any money paid for a work or a replacement copy, if a defect in the electronic work is discovered and reported to you within 90 days of receipt of the work.

- • You comply with all other terms of this agreement for free distribution of Project Gutenberg™ works.

1.E.9. If you wish to charge a fee or distribute a Project Gutenberg™ electronic work or group of works on different terms than are set forth in this agreement, you must obtain permission in writing from the Project Gutenberg Literary Archive Foundation, the manager of the Project Gutenberg™ trademark. Contact the Foundation as set forth in Section 3 below.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.

1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right of Replacement or Refund” described in paragraph 1.F.3, the Project Gutenberg Literary Archive Foundation, the owner of the Project Gutenberg™ trademark, and any other party distributing a Project Gutenberg™ electronic work under this agreement, disclaim all liability to you for damages, costs and expenses, including legal fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.

1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a defect in this electronic work within 90 days of receiving it, you can receive a refund of the money (if any) you paid for it by sending a written explanation to the person you received the work from. If you received the work on a physical medium, you must return the medium with your written explanation. The person or entity that provided you with the defective work may elect to provide a replacement copy in lieu of a refund. If you received the work electronically, the person or entity providing it to you may choose to give you a second opportunity to receive the work electronically in lieu of a refund. If the second copy is also defective, you may demand a refund in writing without further opportunities to fix the problem.

1.F.4. Except for the limited right of replacement or refund set forth in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.

1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the trademark owner, any agent or employee of the Foundation, anyone providing copies of Project Gutenberg™ electronic works in accordance with this agreement, and any volunteers associated with the production, promotion and distribution of Project Gutenberg™ electronic works, harmless from all liability, costs and expenses, including legal fees, that arise directly or indirectly from any of the following which you do or cause to occur: (a) distribution of this or any Project Gutenberg work, (b) alteration, modification, or additions or deletions to any Project Gutenberg work, and (c) any Defect you cause.

Section 2. Information about the Mission of Project Gutenberg

Project Gutenberg is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.

Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg’s goals and ensuring that the Project Gutenberg collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 3. Information about the Project Gutenberg Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws.

The Foundation’s business office is located at 41 Watchung Plaza #516, Montclair NJ 07042, USA, +1 (862) 621-9288. Email contact links and up to date contact information can be found at the Foundation’s website and official page at www.gutenberg.org/contact

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg eBooks with only a loose network of volunteer support.

Project Gutenberg eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
