_One_


The moment arrived when Terry Holt realized that he was simply holding
the bag for Jimenez y Cia.--Jimenez and Company--in the city of Manila.
He wasn't getting anywhere, himself. So, painfully, he prepared to wind
up the company's affairs and his own, and start over. It seemed
appropriate to take inventory, consult the police--they'd been both
amiable and co-operative--and then make new plans. But first it would be
a good idea to go somewhere else for a while, until the problem
presented by _La Rubia_ and radar and fish and _orejas de ellos_ had
been settled. He was at work on the inventory when the door opened, the
warning-bell tinkled, and the girl came into the shop.

He looked up with a wary eye, glancing over the partition separating the
workshop area in which the merchandise sold by Jimenez y Cia. was
assembled. There were certain people he felt should not come into the
shop. The police agreed with him. He was prepared to throw out anybody
who came either to demand that he build something or else, or to demand
that he not build it or else. In such forcible ejections he would be
backed by the authorities of the city and the Philippine Republic.

But this customer was a girl. She was a pretty girl. She was pleasantly
tanned. Her make-up, if she wore any, looked natural, and she carried a
sizable parcel under her arm. She turned to close the door behind her.
She was definitely from the United States. So Terry said in English,
"Good afternoon. Can I do something for you?"

She looked relieved.

"Ah! We can talk English," she said gratefully. "I was afraid I'd have
trouble. I do have trouble with Spanish."

Terry came out from behind the partition marking off the workshop. The
shop was seventeen feet wide and its larger expanse of plate glass said,
"_Jimenez y Cia._" in large letters. Terry's now-vanished partner
Jimenez had liked to see his name in large print. Under the name was the
line "_Especialidades Electronicas y Fisicas._" This was Terry's angle.
He assembled specialties in the line of electronics and modern physics.
Jimenez had sold them, not wisely but too well. At the bottom corner of
the window there was a modest statement: "_Orejas de Ellos_," which
meant nothing to anybody but certain commercial fishermen, all of whom
would deny it.

The girl looked dubiously about her. The front of the shop displayed two
glaringly white electric washing machines, four electric refrigerators,
and two deep-freeze cabinets.

"But I'm not sure this is the right shop," she said. "I'm not looking
for iceboxes."

"They're window-dressing," said Terry. "My former business associate
tried to run an appliance shop. But the people who buy such things in
Manila only want the latest models. He got stuck with these from last
year. So we do--I did do--_especialidades electronicas y fisicas_. But
I'm shutting up shop. What are you looking for?"

The shop was in an appropriate place for its former products. Outside on
the Calle Enero there were places where one could buy sea food in
quantity, mother-of-pearl, pitch, coir rope, beche-de-mer, copra, fuel
oil, Diesel repair-parts and edible birds' nests. _Especialidades_
fitted in. But though it was certainly respectable enough, this
neighborhood wasn't exactly where one would have expected to find a girl
like this shopping for what a girl like this would shop for.

"I'm looking," she explained, "for somebody to make up a special device,
probably electronic, for my father's boat."

"Ah!" said Terry regretfully. "That's my line exactly, as is evidenced
in Spanish on the window and in Tagalog, Malay and Chinese on cards you
can read through the glass. But I'm suspending operations for a while.
What kind of special device? Radar--No. I doubt you'd want _orejas de
ellos_...."

"What are they?"

"Submarine ears," said Terry. "For fishing boats. The name is no clue at
all. They pick up underwater sounds, enabling one to hear surf a long
way off. Which may be useful. And some fish make noises and the
fishermen use these ears to eavesdrop on them and catch them. You
wouldn't be interested in anything of that sort!"

The girl brightened visibly.

"But I am! Something very much like it, at any rate. Take a look at this
and see what my father wants to have made."

She put her parcel on a deep-freeze unit and pulled off its paper
covering. The object inside was a sort of curved paddle with a handle at
one end. It was about three feet long, made of a light-colored fibrous
wood, and on the convex part of its curvature it was deeply carved in
peculiar transverse ridges.

"A fish-driving paddle," she explained. "From Alua."

He looked it over. He knew vaguely that Alua was an island somewhere
near Bohol.

"Naturally a fish-driving paddle is used to drive fish," she said.
"To--herd them, you might say. People go out in shallow water and form a
line. Then they whack paddles like these on the surface of the water.
Fish try to get away from the sound and the people herd them where they
want them--into fish-traps, usually. I've tried this, while wearing a
bathing suit. It makes your skin tingle--smart, rather. It's a sort of
pins-and-needles sensation. Fish would swim away from an underwater
noise like that!"

Terry examined the carving.

"Well?"

"Of course we think there's something special about the noise these
paddles make. Maybe a special wave-form?"

"Possibly," he admitted. "But--"

"We want something else to do the same trick on a bigger scale.
Directional, if possible. Not a paddle, of course. Better. Bigger.
Stronger. Continuous. We want to drive fish and this paddle's limited in
its effect."

"Why drive fish?" asked Terry.

"Why not?" asked the girl. She watched his face.

He frowned a little, considering the problem the girl posed.

"Oh, _ellos_ might object," he said absently.

"Who?"

"_Ellos_," he repeated. "It's a superstition. The word means 'they' or
'them.' Things under the ocean who listen to the fish and the
fishermen."

"You're not serious." It was a statement.

"No," he admitted, still eying the paddle. "But the modern, businesslike
fishermen who buy submarine ears for sound business reasons call them
_orejas de ellos_ and everybody knows what they mean, even in the
modernized fishing fleet."

"Which," said the girl, "Jimenez y Cia. has had a big hand in
modernizing. That's why I came to you. Your name is Terry Holt, I think.
An American Navy Captain said you could make what my father wants."

Terry nodded suddenly to himself.

"What you want," he said abruptly, "might be done with a tape-recorder,
a submarine ear, and an underwater horn. You'd make a tape-recording of
what these whackings sound like under water, edit the tape to make the
whackings practically continuous, and then play the tape through an
underwater horn to reproduce the sounds at will. That should do the
trick."

"Good! How soon can you do it?" she asked.

"I'm afraid not at all," said Terry. "I find I've been a little too
efficient in updating the fishing fleet. I'm leaving the city for the
city's good."

She looked at him inquiringly.

"No," he assured her. "The police haven't asked me to leave. They're
glad I'm going, but they're cordial enough and it's agreed that I'll
come back when somebody else finds out how _La Rubia_ catches her fish."

"_La Rubia?_"

"_The Redhead_," he told her. "It's the name of a fishing boat. She's
found some place where fish practically fight to get into her nets. For
months, now, she's come back from every trip loaded down gunwale-deep.
And she makes her trips fast! Naturally the other fishermen want to get
in on the party."

"So?"

"The bonanza voyages," Terry explained, "started immediately after _La
Rubia_ had submarine ears installed. Immediately all the other boats
installed them. My former partner sold them faster than I could assemble
them. And nobody regrets them. They do increase the catches. But they
don't match _La Rubia_. She's making a mint of money! She's found some
place or she has some trick that loads her down deep every time she puts
out to sea."

The girl made an interrogative sound.

"The other fishermen think it's a place," Terry added, "so they ganged
up on her. Two months back, when she sailed, the entire fishing fleet
trailed her. They stuck to her closer than brothers. So she sailed
around for a solid week and never put a net overboard. Then she came
back to Manila--empty. They were furious. The price of fish had gone
sky-high in their absence. They went to sea to make some money
regardless. When they got back they found _La Rubia_ had sailed after
they left, got back before they returned--and she was just loaded with
fish, and the market was back to normal. There was bad feeling. There
were fights. Some fishermen landed in the hospital and some in jail."

A motor truck rolled by on the street outside the shop of the now
moribund Jimenez y Cia. The girl automatically turned her eyes to the
source of the noise. Then she looked back at Terry.

"And then my erstwhile associate Jimenez had a brainstorm," said Terry
ruefully. "He sold the skipper of _La Rubia_ on the idea of short-range
radar. I built a set for him. It was good for possibly twenty miles. So
_La Rubia_ sailed in the dark of the moon with fifty fishing boats
swearing violent oaths that they'd follow her to hell-and-gone. When
night fell _La Rubia_ put out her lights, used her radar to locate the
other boats who couldn't see her, and sneaked out from their midst. She
came back loaded down with fish. There were more fights and more men in
the hospital and in jail. Some of _La Rubia's_ men boasted that they'd
used radar to dodge their rivals. And that's how the police got
interested in me."

The girl had listened interestedly.

"Why?"

"Oh, Jimenez began to take orders for radar from other fishing boat
owners. If _La Rubia_ could dodge them by radar, they could trail her by
radar even in the dark. So the skipper and crew of _La Rubia_ promised
blood-curdling things as Jimenez's fate if he delivered a radar set to
anybody else. Then the skippers and crews of other boats made even more
blood-curdling threats if he didn't deliver radar to them. So Jimenez
ran away, leaving me to hold the bag."

The girl nodded.

"And therefore," said Terry, "I'm shutting up shop. I'll turn the
inventory over to the police and go off somewhere until someone learns
where _La Rubia_ gets her fish. When things calm down again, I'll come
back and start up business once more--without Jimenez. I'll probably
stick to electric-eye doors, burglar alarms, closed-circuit television
systems and things like that. Then I might make this underwater
broadcasting device, if your father still wants it. I'd better not now."

"We heard about your problem," said the girl. "Almost exactly the way
you just explained it."

Terry stared. Then he said politely, "Oh. You did?"

"Yes, I thought--"

"Then you knew," said Terry more politely still, "that I was leaving
town and couldn't make the gadget you want? You knew it before you came
here?"

"Why," said the girl, "your plans seemed to fit in very nicely with
ours. We've got a sixty-five-foot schooner and we're sailing around. My
father wants something like--what you described. So since you want
to--well--travel around for a time, why not come on board our boat and
make the thing we want there? We'll land you anywhere you like when it's
finished."

"Thanks," said Terry with very great politeness indeed. "I think I made
a fool of myself, explaining. You knew it all beforehand. I'm afraid I
bored you horribly. You probably even know that Jimenez took all the
funds when he ran away."

She hesitated, and then said, "Y-yes. We thought--"

"That I should have trouble raising steamer-fare to any place at all,"
he said without cordiality. "And I will. You had that information too,
didn't you?"

"Please!" she said with distress. "You make it sound--"

"Did you have any idea what I'd charge to assemble the device you want?"

"If you'll name a price."

Terry named one. He was angry. The sum was far from a small one. It was,
in fact, exorbitant. But he felt that he'd made a fool of himself,
responding to her encouragement by telling her things she already knew.

She opened her purse and peeled off bills. She put them down.

"I'll leave the paddle with you," she said crisply. "Our boat is the
_Esperance_. You'll find it...." She named the anchorage, which was that
of Manila's most expensive yacht club. "There's a launch which will
bring you out whenever you're ready to sail. It would be nice if you
could sail tomorrow--and nicer if you could come aboard today."

She nodded in friendly fashion, opened the door--the bell jangled--and
went out.

Terry blinked. Then he swore and snatched up the pile of bills. Two
fluttered to the floor and he lost time picking them up. He went out
after her, the money in his hand.

He saw a taxicab door close behind her, three or four doors down the
street. Instantly the cab was in mad career away. The taxicabs of Manila
are driven by a special breed of chauffeurs. It is said that they are
all escaped lunatics with homicidal tendencies. The cab went roaring
down the Calle Enero's cluttered length and turned the corner.

Terry went back to the shop. He swore again. He looked at the money in
his hand. It totalled exactly the excessive amount he'd named as the
price of an electronic fish-driving unit, including an underwater horn.

"The devil!" he said angrily.

He felt the special indignation some men feel when they are in
difficulties which their pride requires them to surmount by themselves,
and somebody tries to help. The indignation is the greater as they see
less chance of success on their own.

Terry's situation was offensive to him because he shouldn't be in this
kind of situation at all, or rather, his troubles were not foreseeable
by the most competent of graduate electronic engineers. He'd trained for
the work he'd undertaken. He'd prepared himself for competence. At
graduation he'd encountered the representatives of at least three large
corporations who were snapping up engineers as soon as they left the
cloistered halls of learning. Terry'd asked how many men were employed
in the category he'd fit in. When one representative boasted that ten
thousand such engineers were on his company's payroll, Terry declined at
once. He wanted to accomplish something himself, not as part of a team
of some thousands of members. The smaller the organization, the better
one's chance for personal satisfaction. He wouldn't make as much money,
but--

It was a matter of simple logic. If he was better off with a really
small company, he'd be best off on his own. And he'd nearly managed it.
He'd worked only with Jimenez. Jimenez was the sales organization. Terry
was the production staff. In Manila there was certainly room for special
electronic equipment--_especialidades electronicas y fisicas_. He should
have had an excellent chance to build up a good business. Starting
small, even without capital, he'd confidently expected to be going
strong within months. There were taxi fleets to be equipped with
short-wave radio. There were burglar alarms to be designed and
installed, and all sorts of setups to be engineered. And these things
were still in demand. His expectations had a solid foundation. Nobody
could have anticipated the disaster caused by _La Rubia's_ phenomenal
success in commercial fishery. It was even irrational for it to be a
disaster to Terry. But it was.

More immediately, though, he was indignant because this girl had known
all about him when she came into the shop. She'd probably even known
about his gimmicking a standard-design submarine listening device so it
was really good and really directional. But she'd let him talk, asking
seemingly interested questions, when she knew the whole business
beforehand. And at the end she'd done a most infuriating thing by paying
him in advance for something he'd refused to do, thereby forcing him
into the obligation to do it.

He fretted. He needed the money. But he objected to being tricked. He
went back to the probably senseless business of taking an inventory.
Time passed. Nothing happened. Nobody came to the shop. The police had
been firm about _La Rubia_ crewmen calling on Terry to make threats.
They'd been equally firm about other people calling to make
counterthreats. No casual customers entered. Two hours went by.

At four o'clock the door opened--with the sound of its tinkling
bell--and Police Captain Felicio Horta came in.

"_Buenas tardes_," he said cordially.

Terry grunted at him.

"I hear," said Horta, "that you leave Manila."

Terry asked evenly, "Is that a way of asking me to hurry up and do it?"

"_Pero no! Por supuesto no!_" protested Horta. "But it is said that you
have new and definite plans."

"What do you know about them?" demanded Terry.

Police Captain Horta said pleasantly, "Officially, nothing. Privately,
that you will aid some _ricos americanos_ to do experiments
in--_oceanografia_? Some study of oceanic things. That you regret having
agreed to do so. That you consider changing your mind. That you are
angry."

The girl, of course, could have inferred all this from his angry charge
out of the shop with the money in his hand, too late to stop her
taxicab. But Terry snapped, "Now, who the devil told you that?"

Police Captain Horta shrugged.

"One hears. I hope it is not true."

"That what's not true? That I leave? Or that I don't?"

"I hope," said Horta benignly, "that you do as you please. I am not on
duty at the moment. I have my car. I offer myself to chauffeur you if
there is any place you wish to go--to a steamer or anywhere else. If
you do not wish to go anywhere, I will take my leave. With no pre ...
prejudice," he finished. "We have been friendly. I hope we remain so."

Terry stared at him estimatingly. Police Captain Horta was a reasonable
and honest man. He knew that Terry had contributed to matters giving the
police some trouble, but he knew it was accidental on Terry's part. He
would hold no grudge.

"Just why," asked Terry measuredly, "did you come here to offer to drive
me somewhere? Is there any special reason to want me to get out of
town?"

"That is not it," said Horta. "It could be wished that you would--take a
certain course of action. Yes. But not because you would be absent from
here. It is because you would be present at a special other place. The
matter connects with _La Rubia_, but in a manner you could not possibly
guess. Yet you are wholly a free agent. You will do as you please. I
would like to make it--convenient. That is all."

He paused. Terry stared at him, frowning. Horta tried again.

"Let us say that I have much interest in _oceanografia_. I would like to
see certain research carried on."

"Being, I'm sure, especially interested in fish-driving," said Terry
skeptically. "You sound as if you were acting unofficially to get
something done that officially you can't talk about."

Horta smiled warmly at him.

"That," he pronounced, "is a logical conclusion."

"What's the object of the--research, if that's what it is? And why pick
me?"

Horta shrugged and did not answer.

"Why not tell me?"

"_Amigo_," said Horta, "I would like nothing better than to tell you. I
would be interested to see your reception of the idea. But it would be
fatal. You would think me cr-azy. And also more important persons. But
especially me."

It was Terry's turn to shrug his shoulders. He hesitated for a long
moment. If Horta had tried to apply pressure, he'd have turned obstinate
on the instant. But there was no pressure. First the girl and now Horta
tried to lure him with mystery and assurance of interest in high places.

"And _La Rubia's_ involved in the secret?" demanded Terry.

"Innocently," said Horta promptly. "As you are."

"Thank you for faith in my innocence," said Terry with irony. "All
right. If I'm involved, I'm involved. I'll try to devolve out of being
involved by playing along."

He turned to the workshop space at the back of the store. He found boxes
to pack his working tools and the considerable stock of small parts
needed to make such things as burglar alarms, submarine ears and the
assorted electronic devices modern business finds increasingly
necessary. He began to pack them. Surprisingly, Horta helped. Any man of
Spanish blood is apt to be sensitive about manual labor. If he has an
official position his sensitiveness is apt to be extreme. But Horta not
only helped pack the boxes with Terry's stock of parts; he helped carry
them to his car outside. He helped to load them.

Terry turned the key in the door and handed it to him, with the nearly
complete inventory of the shop's contents.

"Jimenez having run away, I leave the shop in your hands," he observed.

Horta put the key and document away. He started the motor of his car and
drove along the Calle Enero. He drove with surprising moderation for a
police officer authorized to ignore traffic rules on occasion. Presently
the dock-area of Manila was left behind, and then the rest of the
commercial district, and then for a time the car tooled along wide
streets past the impressive residences of the wealthy. Some of the
architecture was remarkable. A little further, and the harbor--the
bay--appeared again. The car entered the grounds of Manila's swankiest
yacht club. The design of the clubhouse was astounding. The car stopped
by the small-boat pier. There were two men waiting there. Without being
given any orders, they accepted the parcels Horta handed out. Also
without orders, they carried them out to the float. They loaded them
into the brass-trimmed motor tender which waited there.

"They knew we were coming," said Terry shortly. "Would I have been
brought anyhow?"

"_Pero no_," said Horta. "But there are telephones. When we left the
shop, one was used."

The men who'd carried out the parcels vanished. Terry and Horta stepped
aboard. The tender cast off and headed out into the harbor. There was a
Philippine gunboat and a mine-layer and an American flattop in plain
view. There were tankers and tramp steamers and a vast array of smaller
craft at anchor. A seemingly top-heavy steamer ploughed across oily
water two miles distant. The tender headed for a trim sixty-five-foot
schooner anchored a mile from shore. It grew larger and seemed more trim
as the tender approached it.

The smaller boat passed under the larger one's stern, and the name
_Esperance_ showed plainly. On the starboard side a boat boom projected.
The tender ran deftly up and a man in a sweat shirt and duck trousers
snubbed the line. He said cheerfully, "How do you do, Mr. Holt?" Then he
nodded to Horta. "Good to see you, Captain." He offered his hand as
Terry straightened up on deck. "My name's Davis. We'll have your stuff
aboard right away."

Two young men in dungarees and with crew cuts appeared and took over the
motley lot of cartons that Terry and Horta had made ready.

"Have you everything you need?" asked Davis anxiously. "Would some extra
stuff be useful?"

"I could do with a few items," said Terry, stiffly.

He had quickly developed an acute dislike for the patent attempt to
induce him to join the _Esperance_. He had no reason for his objection,
save that he had not been informed about the task he was urged to
undertake.

"Also," he added abruptly, "Captain Horta didn't think to stop at my
hotel so I could get my baggage."

"Write a list of what you want," suggested Davis. "I'm sure something
can be done about your baggage. Make the list complete. If something's
left over, it won't matter. There's a desk in the cabin for you to write
at." He turned to Horta. "Captain, what's the news about _La Rubia_?"

"She sailed again yesterday," said Horta ruefully. "She was followed by
many other boats. And now there is a moon. It rises late, but it rises.
Many sailors will be watching her from mastheads. It is said that all
the night glasses in Manila have been bought by fishermen...."

His voice died away as Terry went down the companion ladder. Belowdecks
was attractive. There was no ostentation, but the decor was obviously
expensive. There were armchairs, electric lamps, a desk, and shelves
filled with books--two or three on electronics and a highly
controversial one on marine monsters and sea serpents. There were some
on anthropology. On skin diving. On astronomy. Two thick volumes on
abyssal fish. There was a shelf of fiction and other shelves of
reference books for navigation, radio and Diesel maintenance and repair.
There were obvious reasons for these last, but no reason that could be
imagined for two books on the solar planets.

Terry sat at the desk and compiled a list of electronic parts that he
was sure wouldn't be available in Manila. He was annoyed as he realized
afresh the smoothness of the operation that had brought him to the
_Esperance_. He found satisfaction in asking for some multi-element
vacuum tubes that simply couldn't be had except on special order from
the manufacturers back in the United States. But it took time to think
of them.

When he went abovedecks, half an hour later, he had listed just six
electronic components. The tender was gone, and Horta with it. Davis
greeted Terry as cordially as before.

"The tender's left," said Terry with restraint. "Here's my list."

Davis did not even glance at it, but beckoned to one of the crew-cut
young men who'd unloaded the tender.

"This is Nick Alden," he said to Terry. "He's one of the gang. See about
this list, Nick."

The crew-cut young man put out his hand and Terry shook it. It seemed
expected. He went forward with the list and vanished down the forecastle
ladder. Davis looked at his watch.

"Five-thirty," he observed. "A drink might not be a bad thing."

He went below, and Terry surveyed the _Esperance_. She had the look of a
pleasure craft, but was built along the lines of something more
reliable. There was an unusual power winch amidships, with an
extraordinarily large reel. Next to it there was a heavy spar by which
to swing something outboard. There were two boats, well stowed against
heavy weather, and a number of often-omitted bits of equipment, so that
the schooner was not convincing as the hobby of a mere yachtsman.

Then Terry saw the brass-trimmed tender heading out from the yacht-club
float again. Foam spread out from its bow. A figure in it waved. Terry
recognized the girl who'd come into the shop of Jimenez y Cia. She was
smiling, and as the launch came nearer it seemed to Terry that there was
triumph in her smile. He bristled. Then he saw some parcels in the bow
of the tender. Next to the parcels--and he unbelievingly suspected what
they were--he suddenly recognized something else: his suitcases and
steamer-trunk. In order to sail with the _Esperance_ he need not go
ashore to get his belongings. They were brought to him. He became
totally convinced that these people had assumed he'd do what they wanted
him to, without consulting him. He rebelled. Immediately. Any time other
people took for granted that they could make plans for him, he would
become obstinate. When he was in a fix--and now he was practically
stranded in Manila with a need to go elsewhere for a time and no money
with which to do it--he was especially touchy. He found himself scowling
and angry, and the more angry because what was required of him would
have been very convenient if there'd been no attempt to inveigle him
into it.

The launch came around the _Esperance's_ stern. Davis came from below
with two glasses. The girl said cheerfully, "Howdo! We've got your extra
items. All of them. And your baggage."

Terry said curtly, "How did my list get ashore?"

"Nick phoned it," said Davis. "By short-wave."

"And where the devil did you find the stuff I named?"

"That," said Davis, "is part of the mystery you don't like."

"Right!" said Terry grimly. "I don't like it. I don't think I'll play.
I'll go ashore in the tender."

"Hold it!" said Davis. But he was speaking to the operator of the
tender. The crew-cut Nick was in the act of handing up the first piece
of baggage. Davis waved it back. "I'm sorry," he said to Terry. "We'll
stay at anchor here. If you change your mind, the tender will bring you
out any time."

Terry brought out the sheaf of bills the girl had left in the shop of
the vanished Jimenez. He held them out to the girl. She put her hands
behind her back and shook her head.

"We put you to trouble," she said pleasantly, "and we haven't been frank
with you. That's to make up for it."

"I won't accept it," said Terry stiffly. "I insist."

"We won't have it back," said Davis. "And we insist!"

Terry felt idiotic. There was enough of a breeze to make it impractical
simply to put the batch of bank notes down. They'd blow away. The girl
looked at him regretfully.

"I'm truly sorry," she said. "I planned the way we went after you. You
are exactly the person we're sure to need. We decided to try to get you
to join us. We couldn't explain. So we asked what you were like. And
you're not the sort of person who can be hired to do what he's told and
no questions asked. Captain Horta said you were a gentleman. So since we
couldn't ask you to volunteer blindly--though I think you would
volunteer if you knew what we're about to do--we tried to make you come
for the adventure of it. It didn't work. I'm sorry."

Terry had the singular conviction that she told the exact truth. And she
was a very pretty girl, but she wasn't using her looks to persuade him.
She spoke as one person to another. He unwillingly found himself
mollified.

"Look!" he said vexedly. "I was leaving Manila. I need to be away for a
while. I am coming back. I can do any crazy thing I want for some weeks,
or even a couple of months. But I don't like to be pushed around! I
don't like--"

The girl smiled suddenly.

"All right, I'll keep the money."

The girl smiled more widely and said, "Mr. Holt, we are off on a cruise.
We'll put in at various ports from time to time. We think you would fit
into our party. We invite you to come on this cruise as our guest. You
can be helpful or not, as you please. And we will _not_ try to pay you
for anything!"

Davis nodded. Terry frowned. Then he spoke painfully.

"I have a gift for making a fool of myself," he said ruefully. "When
it's put that way, fine! I'll come along. But I reserve the right to
make guesses."

"That's good!" said Davis warmly. "If you do find out what we won't tell
you, you'll see why we didn't."

He waved to Nick and the tender operator. The parcels came onto the
_Esperance's_ deck. His baggage followed. He picked up one of the new
cardboard parcels and examined its markings.

"This," he said more ruefully still, "has me stymied. I'd have sworn you
couldn't get one of these special tubes nearer than Schenectady, New
York. But you found one in Manila in minutes! How did you do it?"

The girl laughed.

"Terribly simple!" she said. "We'll tell you. But not until we're under
way, or you might be so disgusted with the simplicity of it that you'd
want to go ashore again."




_Two_


The edge of the sun touched the horizon and sank below it, out of sight.
There were magnificent tints in the sky, and the gently rippling harbor
water reflected them in innumerable swirlings of color. The _Esperance_
swayed very slightly and very gracefully on the low swells. In minutes
two of the dungareed members of the ship's company got the anchor up
with professional efficiency. One of them went below, and the
_Esperance's_ engine began to rumble. Davis casually took the wheel, and
the small yacht began to move toward the open sea while Nick played a
salt-water hose on the anchor before lashing it fast. The brief twilight
of the tropics transformed itself swiftly into night. Lights winked and
glittered ashore and on the water.

Terry felt more than a little absurd. The girl said pleasantly, at his
side, "My name's Deirdre, in case you don't know."

"Mine's Terry, but you do know."

"Naturally!" she said briskly. "I should explain that I'm the ship's
cook, and the boys forward aren't professional sailors, and my father
isn't--"

"Isn't in this business for money," said Terry. "It's strictly for
something else. And I don't think it's buried treasure or anything like
that."

"Nothing so sensible," she agreed. "Now, if you want to join a watch,
you'll do it. If you don't, you won't. The port cabin, the little one,
is yours. You are our guest. If you want anything, ask for it. I'm going
below to cook dinner."

She left him. He surveyed the deck again, and presently went back to
where Davis sat nonchalantly by the _Esperance's_ wheel. Davis nodded.

"Now that you've, well, joined up," he said meditatively, "I've been
trying to think how to, well, justify all the mystery. Part of it was
Deirdre's idea. She thought it would make our proposition more
interesting, so you'd be more likely to take it up. But when I think
about explaining, I bog down immediately."

Terry sat down. The _Esperance_ drove on. Her bow lifted and dipped and
lifted and dipped. The water was no longer nearly smooth. There was the
beginning of a land breeze.

"There's _La Rubia_," said Davis uncomfortably. "You outfitted her with
underwater ears and a radar, at least. Was there anything else?"

"No," said Terry curtly. "Nothing else."

"She catches the devil of a lot of fish," said Davis. He frowned. "Some
of them you might call very queer fish. You haven't heard anything about
that?"

"No," said Terry. "Nothing."

"I think, then," said Davis, "that I'd better not expose myself to
scorn. I'd like to be able to read her skipper's mind, though. But it's
possible he simply thinks he's lucky. And it's possible he's right."

Terry waited. Davis puffed on his pipe. Then he said abruptly, "Anyhow
you're a good man at making gadgets. We'll let it go at that, for the
time being."

The sea became less and less smooth. There were little slapping sounds
of waves against the yacht's bow. The muted rumble of her engine was not
intrusive. The breeze increased. Davis gave a definite impression of
having said all he intended to say for the time being. Terry stirred.

"You want me to build a gadget," he said. "To drive fish. Would you want
to give me some details?"

Davis considered. A few drops of spray came over the _Esperance's_ side.

"N-o-o-o," said Davis. "Not just yet. There's a possibility it will fit
in. I'd like you to make one, and maybe it will fit in somewhere. But
_La Rubia's_ the best angle we've got so far. There is one gadget I'd
give a lot to have! You know, a depth-finder. It sends a pulse of sound
down to the bottom and times the echo coming back. Very much like radar,
in a way. Both send out a pulse and time its return."

Terry nodded. There was no mystery about depth-finders or radars.

"We've got a depth-finder on board," said Davis. "If I sail a straight
course and keep the depth-finder running, I can make a profile of the
sea bottom under me. If I had a row of ships doing the same thing, we
could get profiles and have a relief map of the bottom."

"That's right," agreed Terry.

"What I'd give a lot for," said Davis, "would be a depth-finder that
would send spot-pulses, like radar does. Aimed sound-pulses. And an
arrangement made so it could scan the ocean bottom like radar scans the
sky. One boat could make a graph of the bottom in depths and heights,
mapping even hummocks and hills underwater. Could something like that be
done?"

"Probably," Terry told him. "It might take a good deal of doing,
though."

"I wish you'd think about it," said Davis. "I know a place where I'd
like to use such a thing. It's in the Luzon Deep. I really would like to
have a detailed picture of the bottom at a certain spot there!"

Terry said nothing. He'd been made angry, then mollified, and now he
felt tempted to grow angry again. There was nothing definite in what was
wanted of him, after elaborate machinations to get him aboard the
_Esperance_. He was disappointed.

"Good breeze," said Davis in a different voice. "We might as well hoist
sail and cut off the engine. Take the wheel?"

Terry took the wheel. Davis went forward. Four dungareed figures came up
out of the forecastle. The sails went up and filled. The engine stopped.
The motion of the boat changed. More spray came aboard, but the movement
was steadier. Davis came back and took the wheel once more.

"I think," he said, "that we're acting in a way to--hm--be annoying. I
ought to lay my cards on the table. But I can't. For one thing, I
haven't drawn a full hand yet. For another, there are some things you'll
have to find out for yourself, in a situation like this."

"Such as--"

"Well," said Davis with a sudden dogged air, "take those _orejas de
ellos_, for an example. _Ellos_ are supposed to be some sort of beings
at the bottom of the sea who listen to fish and fishermen. It's a
superstition pure and simple. Suppose I said I was investigating the
possibility that there were such--beings. You'd think I was crazy,
wouldn't you?"

Terry shrugged.

"What I am interested in," said Davis, "has enough credit behind it for
me to get some pretty rare electronic parts from the flattop in harbor
back yonder. Nick called them by short-wave, they sent the parts ashore
and gave them to Deirdre, and she brought them out to you."

Terry blinked. Then he realized. Of course, that was where just about
any imaginable component for electronic devices would be found--in the
electronics stores of a flattop! They needed to have such things at
hand. They'd carry them in store. Davis said drily, "They wouldn't
supply parts to a civilian who was investigating imaginary gods or
devils. So what I'm bothered with isn't a superstition. Right?"

"Y-yes," agreed Terry.

It was true. The Navy would not stretch regulations for a crackpot
civilian. It was not likely, either, that Horta would have implied so
definitely that the Philippine Government wanted somebody with Terry's
qualifications to go for a cruise on the _Esperance_.

Deirdre put her head up through the after-cabin hatch.

"Dinner is served," she said cheerfully.

"The wheel," said Davis to Terry.

He went forward. All four of the non-professional seamen came with him
when he returned.

"This is the rest of the gang," said Davis. "You met Nick. The others
are Tony Drake, Jug Bell, and Doug Holmes." He made an embracing gesture
as they shook hands in turn. "Harvard, Princeton, Yale--and Nick's
M.I.T. It's your turn at the wheel, Tony."

One of the four took over. The others filed below after Davis and Terry.
Terry was silent. Davis had wanted to show that he was being
informative, and yet he'd said exactly nothing about the interests or
the purpose of the _Esperance's_ complement.

Dinner in the after-cabin was almost as confusing to Terry. Seen at
close range across a table, the four dungareed young men could not
possibly be anything but college undergraduates. They were respectful to
Davis as an older man and they tended to be a little cagey about Terry,
because he was slightly older than themselves but not an honorary
contemporary. They plainly regarded Deirdre with the warmest possible
approval.

Conversation began, at first cryptic but suddenly only preposterous.
There was an argument about the supposed intelligence of porpoises,
based on recent studies of their brain structure. Tony observed
profoundly that without an opposable thumb intelligence could not lead
to artefacts, and hence no culture and no great effective intelligence
was possible. Jug denied the meaningfulness of brain structure as an
indication of intellect. Intellect would be useless to a creature which
could neither make nor use a tool. Doug argued hotly that the point was
absurd. He pointed to spastic children once rated as morons but actually
having high I.Q.'s. They had intellects, though they had been useless
because of their inability to communicate. But Nick asserted that
without tools they'd have nothing to talk about but food, danger, and
who went where with whom for what. All of which, he observed, needed no
brains.

Davis listened amusedly. Deirdre threw in the suggestion that without
hands or tools an intelligent creature could compose poetry, and Jug
protested that that was nothing to use a brain for--and the talk turned
into a violent argument about poetry. Doug insisted vehemently that the
finest possible intellects were required for the composition and
appreciation of true poetry. Then Davis said, "Tony's still at the
wheel."

The argument died down and the crew-cuts devoted themselves to eating,
so one of them could get through and relieve him.

Afterward, Davis settled down below to a delicate short-wave tuning
process to get music from an improbable distance. Deirdre served Tony
his meal and talked with him while he ate it. Terry went abovedecks and
paced back and forth as the _Esperance_ sailed on through the night.

He couldn't make out anything at all about the crew or the purpose
behind the _Esperance's_ chosen task and purpose. He felt dubious about
the whole business. Like most technically-minded men, he could become
absorbed in a problem, especially if it was a device difficult to design
or a design that somehow didn't work. Such things fascinated him. But
the _Esperance's_ crew was not concerned with a problem like that. There
was no pattern in their talk or behavior to match the way a technical
mind would go about finding a solution. The problem was bafflingly
vague, yet there _was_ one.

_La Rubia_ was an element in it. Possibly Davis' wistful mention of a
partial map of the bottom of the Luzon Deep fitted in somewhere. Davis
had spoken of _orejas de ellos_ with some familiarity, but certainly no
Navy ship would cooperate in the investigation of a fisherman's
superstition in which even fishermen didn't believe any longer. The
Philippine fishing fleet was modern and efficient. Fishermen used
submarine ears without superstitious fears, and if they referred to
imaginary _ellos_ it was as an American would say "knock on wood," with
no actual belief that it meant anything.

Whatever the _Esperance's_ purpose was, there was nothing mystical about
it--not if a flattop parted with rare and expensive specialized vacuum
tubes to try to help, and the police department of Manila urged Terry
tactfully--through Horta--to join the yacht, and no less than a Navy
Captain had named him as someone to be recruited.

Deirdre came abovedecks and replaced Tony at the wheel. The _Esperance_
sailed on. A last-quarter moon was now shining low on the eastern
horizon. It seemed larger and nearer to the earth than when seen from
more temperate climes. The wake of the yacht glowed in the moonlight.

The wide expanse of canvas made stark contrast between its moonlit top
and its shadow on the deck. The only illumination on the ship was the
binnacle lights and the red and green running lights. Deirdre kept the
_Esperance_ on course.

Terry went up to where she sat, beside the wheel.

"I've been making guesses," he told her. "Your father.... I believe that
his curiosity has been aroused by something, and he's resolved to track
it down. I strongly suspect that at some time or another he's gotten
bored with making money and decided to have some fun."

Deirdre nodded.

"Very good! Almost completely true. But what he's interested in is a
good deal more important than fun."

Terry nodded in his turn.

"I suspected that too. And it's rather likely that you've got a
volunteer crew instead of a professional one because these young men
consider it a fascinating adventure into the absurd, and because they'll
keep their mouths shut if something turns out to be classified
information."

"My father's doing this strictly on his own!" said Deirdre quickly.
"There's nothing official about it. There isn't any classified
information about it. This is a private affair from the beginning!"

"But in the end it may turn out to be something else," said Terry.

"Y-yes. We don't know, though. It's impossible to know!
It's--ridiculous!"

"And my explanation for your being so mysterious with me is that you and
your father insist that I find out everything for myself because I'd
think it foolish if you told me."

Deirdre did not answer for a moment. There was a movement behind Terry,
and Davis came on deck.

"That was good music!" he said pleasedly. "You missed some very
interesting sounds, Deirdre! You too, Holt."

"He's decided," said Deirdre, "that we're a little bit ashamed of our
enterprise and won't tell him about it for fear he'll simply laugh at
us."

Terry protested, "Not at all! Nothing like that!"

"When some forty-odd people have been killed by something inexplicable
at one time that we know of," said Davis, "--and we don't know how many
others have been killed at other times, or may be killed by it in the
future--I don't think that's a laughing matter."

He surveyed what should be the direction of the land. A light showed
there and vanished, then came on again and vanished. A minute later it
showed and disappeared, then came on again twice. It was very far away.
Davis said in a different tone, "We can change course now, Deirdre. You
know the new one."

The _Esperance's_ bowsprit forsook the star at which it had been aiming.
It swung to another. Davis moved about, adjusting the sheets alone. On
the new heading the yacht heeled over a little more and the water
rushing past her hull had a different sound. The sky seemed larger and
more remote than it ever appears from a city. The yacht's wake streamed
behind her in a trail of bluish brightness. Even the moon was strange.
It had the cold enormousness of something very near and menacing. It
looked as close as when seen through a telescope of moderate power.

The _Esperance_ seemed very lonely on the immense waste of waters.

Next morning, of course, the sense of loneliness was gone. There was
neither land nor any ship in sight, but gulls fluttered and squawked
overhead, and the waves seemed to leap and gambol in the sunshine. Just
before the foremast a metal plate in the decking had been lifted up, and
a new, stubby, extensible mast rose almost as high as the crosstrees. A
tiny basket-like object rotated monotonously at its upper end. It was a
radar-bowl, and somehow it was not unusual, except in the manner in
which it was mounted. Yet, such a collapsible radar mast was reasonable
on a sailing yacht with many lines aloft that could be fouled. Anyhow,
the radar was concerned with human affairs, and so it was company.

The housekeeping work on the boat was in progress. Doug and Jug scrubbed
the deck. The other crew-cuts gave signs of industry from time to time,
appearing and vanishing. Davis smoked tranquilly at the wheel. Terry
felt useless, as well as puzzled.

"Can I do anything?" he asked awkwardly.

"You're your own boss," said Davis.

"Then I might as well see what can be done about that submarine
noisemaker."

"If you feel like it," said Davis, "fine!"

But he did not urge. Terry waited a moment. There was a sort of
contagion of purposefulness in this eccentric small group on the
_Esperance_. They had something they were trying to do, and it seemed
important to them. But Terry was an outsider and would remain one until
he became active in their joint effort.

He got out his equipment and materials and spread them out. There was no
need to build a recorder, since there was one among the supplies. The
rest wouldn't be unduly difficult. He established a working space and
set systematically to work. The task he'd accepted was essentially
simple. A submarine ear was to pick up underwater sounds. He had to
modify a microphone and enclose it in a water-tight housing, with
certain special features that would make it highly directional. The
recorder would take the pick-up and register it on magnetic tape, while
playing it for simultaneous listening. Then he had to assemble a
machine for playing back the taped sounds under water. That required a
unit for a submarine horn, to broadcast the amplified sound. It isn't
difficult to make a sound under water. One can knock two stones together
under the surface and a swimmer can hear it a mile or more away. But a
horn to reproduce specific sounds is more difficult to build. It needs
extra power. A sound-truck in a city, competing with all the traffic
noises, will turn no more than fifteen watts of electricity into noise.
But much more power would be needed to produce a similar volume under
water.

Terry modified the mike into a submarine ear--an _orejas de ellos_. Then
he began to assemble an audio amplifier to build up the volume of the
sounds already taped for re-use under the sea. He had the parts. It was
mostly just finicky labor. He sat cross-legged in the sunshine, not far
from the _Esperance's_ unusual winch.

Nick came up from below and went aft. He spoke to Davis. Terry couldn't
hear what was said, but Davis gave orders.

The _Esperance_ heeled over; away, away over. The four crew-cuts
adjusted the sheets for maximum effect of the sails on the new direction
of motion. The yacht seemed to tear through the water like a racing
boat. Terry had to rescue some of his smaller parts which started for
the scuppers. He looked up. Deirdre said cheerfully, "Our radar picked
up a boat that's probably _La Rubia_ on the way back to Manila. We don't
want her to see us."

Terry blinked.

"Why?"

"We're going to take a look at the spot where we think she catches her
fish," said Deirdre. "It's strange enough that she catches so many, but
what's even stranger is the kind of fish she catches at times."

"How?"

Deirdre shrugged. Then she said irrelevantly, "_La Rubia's_ skipper
would like to have the only radar in the world, as you've reason to
know, and he doesn't think of radars, except his own and possible
competitors. But there are lots of others. We're probably a blip on
somebody's radar-screen right now. In fact, we're supposed to be. So
when my father got interested in _La Rubia_ and her--catches, he was
able to have somebody notice where she goes every time she slips away
from the fishing fleet. And so he was told. It was all quite unofficial,
of course."

Terry bent over his task again while the _Esperance_ sped along over the
off-shore swells. There was no land in sight anywhere. An albatross
glided overhead for a time, as if inspecting the _Esperance_ as a
possible source of food. When Terry looked for it later it was gone.
Once there was a flurry in many wave-flanks, and a small school of
flying fish darted out of the sea with hazy, beating fins, and dived
back into the sea many yards from where they started.

But nothing of any consequence happened anywhere. Terry fitted and
soldered and tested. By noon he had a rather powerful audio amplifying
unit, set up to magnify any sound the tape-recorder fed into it. Deirdre
prepared a meal. The galley of the _Esperance_ was admirably supplied
with all kinds of food. After the noon meal the yacht changed course
again to a line which would intersect her original morning course at
some point.

Terry found himself fuming. He'd set to work to make something that
Davis apparently wanted, but his most elementary questions still ran
against a blank refusal to answer. Both Davis and Deirdre had spoken of
oddities in the catches of _La Rubia_. There could not possibly be any
reason for them to refuse to tell him what they were. Terry worked
himself into irritability, recalling how he volunteered to come on the
_Esperance_ but not thinking that he would be treated as someone who
wasn't allowed to know what everybody else aboard most certainly did.

In the afternoon there was guitar music down in the forecastle, and Doug
came out and settled himself on the bowsprit with a book of poetry.
Presently Nick sat down close by Terry and watched interestedly as he
put mysterious-looking electronic elements together into
incomprehensible groups. When he had finished, Terry did not admire his
handiwork. The noisemaking unit came last. The electrical part had to be
enclosed, water-tight, with a diaphragm exposed to the water on one
side and its working parts protected from all moisture on the other. The
device looked cobbled, but it worked, and made monstrous sounds in the
air.

Now he plugged the submarine ear into the recorder. He dropped it
overside and taped the random noises of the sea: the washings of sea
water against the _Esperance's_ hull, frequent splashings, and very
faint, chirping noises from who-knew-what.

"Watch the volume, will you?" Terry pointed out the Indication that
should not be exceeded. Nick nodded. "I'm going to whack the paddle
overside and see what we get in the way of noise."

Nick hesitated. Then he said uneasily, "Wait a minute."

He went aft to Davis, apparently somnolent at the wheel. Deirdre joined
the two of them in a seemingly very serious discussion. Then she walked
over to Terry.

"I hate to say it," she told him with evident concern, "but my father
thinks it would be wiser to try out the paddle in shallow water. Do you
mind?"

"Yes," snapped Terry. "I do mind, since I'm not allowed to know the
reason for that or anything else."

He put away his tools and the unused parts. He pointed to the machines
he had already built.

"This is what your father wanted, I think. After it's tested I'll ask
you to put me ashore."

He went below, where he fretted to himself. But no one came, either to
inform him of Davis' reasons, or to tell him to do as he pleased. He
felt like a child who isn't allowed to play with other children; who is
arbitrarily excluded from the purpose and the excitement of his fellows.
Thinking in such terms did not make him feel any better. His irritation
increased. The _Esperance_ was engaged in an enterprise that these
people considered very much worth doing. He'd joined them to accomplish
it, and they wouldn't tell him what it was. He hadn't the temperament to
be content with just following blindly. And somehow the fact that
Deirdre was aboard and a participant in the secret made his exclusion an
insult.

He felt about Deirdre that urgent concern that a man may feel about one
or two, or at most three girls during his whole lifetime. It wasn't a
romantic interest, at this stage, but he wanted to look well in her
eyes, and he was enormously interested in anything she said and did. If
he left the _Esperance_ and ceased to know her, he knew he'd be nagged
at by the feeling that he'd made a very bad mistake. He didn't want to
stop knowing her. But he refused to be patronized.

He saw an open book on the after-cabin table and glanced restlessly at
it. There were three or four photographs and a newspaper clipping stuck
into its pages. The book itself dealt with physics at post-graduate
levels--which meant that it included a good deal about electronics.

Still fuming, Terry glanced at the pictures. The first was of a
spherical object made of transparent plastic and probably of small size.
It had a number of metallic elements clearly visible through the
transparent case. It looked as if it might be an electronic device
itself, but there was no sign of lead-in contacts, and the parts inside
made no sense at all. The second and third photographs were of a similar
yet slightly different object. The fourth photograph was a picture of
what looked like ocean water, taken from a plane. The horizon showed in
one corner. The center of the picture was an irregularly-shaped mass of
white. On close examination it appeared to be foam. But it looked as if
it were piled up in masses above the surface. If the water around it was
ocean--and it was--and the visible crest-lines were of waves--and they
were--that heap of foam must have been hundreds of yards in diameter and
piled many feet high on the surface. Foam does not form in such masses
in the open sea. It would not last if it did.

On the margin of this picture a date had been inked--three days
before--and a position in degrees of latitude and longitude.

Terry turned to the chart rack. He pulled out a chart and looked up the
position. Someone had made a pencil-dot there. It was close to Thrawn
Island, on the very brink of the Luzon Deep, that incredible submarine
chasm in which the entire Himalayan chain could be sunk without showing
a single pinnacle above the surface.

He went back to the clipping. It was dated Manila, two years earlier. It
was an obviously skeptical article on a report made by the crewmen of a
sailing ship that stopped by Manila. Sailing ships are rare enough in
modern times. This ship reported that she had sighted another of her own
kind at sea. The two ships altered course to speak to each other. And
the one which came into Manila declared that when the other vessel was
no more than two miles away, white foam suddenly appeared on the sea
just in front of her. A geyser of unsubstantial white stuff spouted up
and spread, shooting up about thirty feet on the water. The bow of the
other sailing ship entered the foam patch. And suddenly her bow tilted
downward, her masts swayed forward, and the entire ship vanished into
the white stuff, exactly as if she had sailed over a precipice. She did
not sink. She dropped. She "fell" under water--under the foam--her sails
still spread. One instant she sailed proudly. The next instant she was
gone.

The position of such an incredible happening was roughly given. It was
almost exactly the same as the position written on the photograph of
foam taken from the air. At the margin of the Luzon Deep.

Terry found that his indignation had evaporated. The reason for it still
remained, but now he wanted to know more about this happening and about
the spheres of plastic with those deftly designed but enigmatic
inclusions. The plastic objects had a purpose. He wanted to know what.
And the news clipping....

Having announced crossly that he would ask to be set ashore as soon as
the fish-driving unit was tested, he was ashamed to take it back. He
stayed below, now angry at himself again. Nobody came below. Deirdre did
not descend to cook. Night fell. Well after nightfall he heard movements
on deck, and presently a voice which sounded oddly distant. The
_Esperance's_ course changed abruptly. The quality of her motion altered
once more.

He went abovedecks. Twilight was long over, but the moon was not yet up.
Here and there a wave-tip frothed, and blue luminescence appeared. Here
and there a streak of dim blue light could be seen under water, where
some fish darted. But those dartings were rare. Despite the yacht's
shining wake and the curling wave-tips, the sea was darker than usual.

Nick's voice came from aloft, faint and eerie and seeming to come from
the stars.

"... farther to port.... Two points ..."

Terry could see the masthead weaving and swaying against the stars, with
a small dark silhouette clinging to it: Nick. The yacht began to swing.
On one bearing she pounded heavily. The seas could hit her squarely, and
they did. Figures moved swiftly about the deck, loosening sheets or
tightening them. Nick's voice again, from overhead.

"Stea-a-a-dy!"

The _Esperance_ ceased to turn. Rushing, pounding water sprayed in the
air. The waves splashed upon the hull of the yacht, which was sweeping
along on a quartering wind.

For a while no one talked. Tony stood at the wheel, with Davis nearby,
by the binnacle light. Terry could see Davis glancing into the binnacle,
then gazing at the horizon ahead, and then aloft, where Nick seemed to
swing among low-hanging stars.

"Ri-i-i-ght!" he called from high overhead. "Steady as she goes."

The _Esperance_ sailed on, over the surging seas. Waves came out of
nowhere, leaped beside the yacht and then went by--to nowhere. It was
hard to believe that the yacht actually moved forward. She seemed to
stay perpetually in the one spot. But there was a winding, sinuous wake,
and there was froth under her forefoot.

Then a vague brightness appeared on the sea, at the limit of vision. It
spread out more widely as the _Esperance_ approached. Presently it was
clearly visible.

Dead ahead, the beam of the headlight suddenly revealed an incredible
spectacle. Until then there had been just a few flashes in the water,
where some fish darted away from the yacht's bulk. But here the entire
surface of the water shone with thousands and thousands of fish. They
were packed in a sharply delimited circle about a mile wide. When the
_Esperance_ got close enough, she hauled up into the wind to look.

From a spot fifty yards ahead, the sea was alive with a million frantic
dartings of swimming things. They were crowded, packed almost
fin-to-fin. And it was not a surface phenomenon only. From the yacht's
deck the streaks of light were visible deep down, as far as the clear
water would let them be seen. They formed a column of glittering chaos.
The vast circle, to an indefinite depth, was packed solid with agitated
fish. At that edge of brightness the thronging creatures were splashing
in a mad frenzy. Solid shining shapes leaped crazily from the water.
Some leaped again and again, until they reached the spot where the
flashes were thickest, and got lost in the multitude of their fellows. A
few escaped to the darker surrounding sea. They seemed to run away in
stark terror. But those were only a few. The greatest mass of fish
milled crazily inside the circle. There were even porpoises, darting
about as if frightened beyond all normal behavior, not even trying to
feed on the equally fear-maddened creatures all about them.




_Three_


Terry stared incredulously. Someone moved beside him. It was Davis. He
spoke in a dry voice.

"I would think," he said detachedly, "that _La Rubia_ could catch a
boatload of fish in that water with a single haul of her nets. Certainly
with two."

Terry turned his head.

"But what is it? What makes these fish gather like this?"

"An interesting question," said Davis. "We'll try to find out how it
happens. Even more interesting, I'd like to know why."

He moved away along the deck. Terry went close to the side rail. A few
minutes later the startling glare of one of the side searchlights smote
upon the water away from the incredible scene. It moved slowly back and
forth. Where the light struck, the sea seemed totally commonplace. No
fish could be seen. Then the white beam swept here and there in jerky
leapings. There was nothing unusual on the surface, nothing beyond the
limit of brightness, where the sea turned dark.

Deirdre said at Terry's side, "We didn't really expect this! I'm going
to get a sample of the water, Terry. Want to help?"

She ignored his haughty withdrawal of the afternoon, and he could not
stand on his dignity in the presence of such an incredible phenomenon.
She got a water bucket from the nearby rack. A wave sprung up as she
tried to fill the bucket overside. It touched her hand and she cried
out. Terry jerked her back by the shoulder. The bucket bumped against
the _Esperance's_ side, hanging on the line attached to the rail.

"What's the matter?"

"It stung! The water stung! Like a nettle!" Shaking a little, Deirdre
rubbed her wet hand with the other. "It doesn't hurt now, but it was
like a stinging nettle--or an electric shock!"

Terry hauled in the bucket and set it down. He leaned far over the rail.
He plunged his hand into a lifting pinnacle of the sea. Instantly, his
skin felt as if pricked by ten thousand needles. But his muscles did not
contract as they would in an electric shock. The sensation was on the
surface of his skin alone.

He shook his head impatiently. He put his finger in the bucket he'd
lifted to the deck. There was no unusual sensation. He dipped overside
again. Again acute and startling hurt, from the mere contact with the
water.

Deirdre still rubbed her hand. She said in a queer, surprised voice,

"Like pins and needles. It's like--like the fish-driving paddle! But
worse! Much worse!"

Terry looked again at the sea glittering with the swarms of fish in
hopeless, panicked agitation, confined in a specific narrow compass by
something unguessable. The searchlight continued to flick here and
there. The _Esperance_ drifted away from the edge of brightness. Terry
put his hand overside once more, and once more he felt the stinging,
nettle-like sensation. He got a fresh bucket of water from overside. On
deck, there was no strange sensation when he dipped his hand in it.

The searchlight went out abruptly and only a faint and quickly dimming
reddish glow came from it. That too died.

Davis' voice gave orders. Terry said sharply, "Wait a minute!" He began
to explain about the stinging of the water. But then he said, "Deirdre,
you tell him! I'm going to put a submarine ear overboard. At the least
we'll get fish noises on a new scale. But I've got an idea ... don't
sail into the bright circle yet."

He got out the submarine ear and the recorder he'd made ready that
afternoon. He started the recorder. Then he trailed the microphone
overside. The sounds would be heard live through the speaker and they
would be taped at the same time. At first, a blaring, confused sound
came through. Terry turned down the volume.

He heard gruntings and chirpings and rustlings. Fish made those
noises--not all fish, but certain species. These shrill, squeaking
noises were the protests of frightened porpoises. But under and through
all other sounds, a steady, unvarying hum could be easily detected.
Terry had never heard anything quite like it. Its pitch was the same as
that of a sixty-cycle frequency, but its tone quality was somehow
sardonic and snarling. The word that came into Terry's mind was "nasty."
Yes, it was a nasty sound. One didn't like it. One would want to get
away from it. In the air the same unpleasant sensation is produced by
noises that make one's flesh crawl.

Terry straightened up from where the recorder played upon the wet deck.
Davis and Deirdre had come to listen, in the strange darkness under the
sails of the _Esperance_.

"I've got a sort of hunch," said Terry slowly. "Let's sail across the
bright patch. I'll record the sea noises all the way. I've a feeling
that that hum means something."

"It's not what you'd call an ordinary sound," said Davis.

He raised his voice. One of the crew-cuts was at the schooner's wheel.
He spun it. The sails filled, and the rattling of flapping canvas died
away. The _Esperance_ gathered way and moved swiftly from the glittering
circle, came about, and sailed again toward the shining area. She got
closer and closer to the boundary.

The recorder continued to give out the confused and frightened noises of
the sea creatures, but under and through their sounds there remained the
nasty and sardonic hum. It grew louder and more unpleasant--much louder
in proportion to the fish sounds. At the very boundary of the bright
space it was loudest of all.

But as the yacht went on, the hum dimmed. At the very center of the
circle where the glitterings were brightest, the humming sound was
overwhelmed by the submarine tumult of senseless fish voices. Terry
dipped his hand here. The tingling was almost tolerable, but not quite.

Davis hauled more buckets of water to the deck. In two of them he found
some fish, so dense was the finny multitude. Then the yacht neared the
farthest limit of the bright circle. The hum from the recording
instrument grew progressively louder. Again, at the very edge of the
shining water, it was loudest.

The _Esperance_ sailed across the live boundary and into the dark sea.
As the boat went on, the sound dimmed....

"Definitely loudest," said Terry absorbedly, "at the edge of the circle
of fish. At the line the fish couldn't cross to escape. It is if there
were an electric fence in the sea. It felt like that, too. But there
isn't any fence."

Davis asked evenly, "Question: what holds them crowded?"

Terry said again, groping in his mind, "They act like fish in a closing
net. I've seen something like this once, when a purse-seine was hauled.
Those fish were frantic because they couldn't get away. Just like
these."

"Why can't they get away?" asked Davis grimly. "We haven't seen anything
holding them."

"But we heard something," pointed out Deirdre. "The hum. That may be
what closes them in."

Her father made a grunting noise. "We'll see about that."

He moved away, back to the stern. In moments, the _Esperance_ was
beating upwind. Presently, she headed back toward her previous position,
but outside the brightness. Terry could see dark silhouettes moving
about near the yacht's wheel. Then he saw another brightness at the
eastern horizon, but that was in the sky. Almost as soon as he noticed
it, the moon peered over the edge of the world, and climbed slowly to
full view, and then swam up among the lower-hanging stars.

Immediately, the look of the sea was different. The waves no longer
seemed to race the darkness with only star glitters on their flanks. The
figures at the _Esperance's_ stern were now quite distinct in the
moonlight.

"You said a very sensible thing, Deirdre," said Terry. "I thought of the
fish-driving paddle and its effects, but I was ashamed to mention it. I
thought it would sound foolish. But when you said it, it didn't."

"I have a talent," said Deirdre, "for making foolish things sound
sensible. Or perhaps the reverse. I'm going to say a sensible thing now.
We haven't had dinner. I'm going to fix something to eat."

"You won't get anybody to go belowdecks right now!" said Terry.

"I thought of that," she told him. "Sandwiches."

She went below. Terry continued to watch, while figures at the stern of
the schooner went through an involved process of visual measurement. It
was not simple to determine the dimensions of a patch of shimmering
light flashes from a boat in motion. But presently, Davis came toward
him.

"It's thirteen hundred yards across," he told Terry. "Plus or minus
twenty."

"I didn't expect all this," Davis said, frowning. "I've been making
guesses and hoping fervently that I was wrong. And I have been, but each
time the proof that I was wrong has led to new guesses, and I'm afraid
to think those guesses may be right."

"I can't begin to guess yet," said Terry.

"You will!" Davis assured him. "You will! You try to add up things.... A
half-mile-wide patch of foam that piles up thirty feet above the
sea...."

"And into which," Terry interrupted, "a sailing ship does not sink but
drops out of sight as if there were a hole in the sea."

Davis turned sharply toward him.

"There were some photographs and a newspaper clipping on the cabin
table," explained Terry. "I suspected they might have been put there for
me to see."

"Deirdre, perhaps," said Davis. "She's resolved to involve you in this.
You've got scruples, so she suspects you of having brains. Yes. You'll
add those things up. You'll include the remarkable success of a fishing
boat named _La Rubia_ and the fact that she sometimes brings in very
strange fish ... And then you'll add ..."

His eyes flickered aloft. A shooting star streaked across one-third of
the sky leaving a trail of light behind it. Then it went out.

"You'll even be tempted," said Davis, "to include something like that in
your guesses! And then you'll try to come up with a total for the lot.
Then you'll be as troubled as I am."

He paused a moment.

"You said you wanted to be put ashore as soon as the gadget you made
today was tested. I hope you've changed your mind, or will. That
tape-recording may mean something to somebody. We wouldn't have heard
that very singular noise but for you."

"I withdraw the business of going ashore," said Terry uncomfortably.
"I'm going to ask another question. What are those little spheres that I
saw in the photographs on the cabin table? Were they found fastened to
the fish?"

"So I'm told," said Davis. "They are made of plastic. One was on a fish
caught by a chief petty officer of the United States Navy. Four have
been found on fish brought into the market by _La Rubia_. They could
conceivably be a joke, but it's very elaborate! Somebody tried to cut
one open and it burst to hell-and-gone. Terrific pressure inside. The
metal parts inside were iridium. The others haven't been cut open.
They're--" Davis' tone was dry. "They're being studied."

A figure came out of the forecastle and walked aft. It was Nick. He
stopped to say, "I called Manila and got a loran fix on us. We're right
at the place _La Rubia_ heads for every time she sneaks away from the
rest of the fishing fleet. It seems that she hauls her nets yonder."

He nodded toward the circular area of luminosity on the sea. "It looks
smaller than when I went below deck."

Davis stared. He seemed to stiffen.

"It does. We'll make sure."

He went aft. Deirdre came up with sandwiches. Terry took the tray from
her and followed her toward the others.

"Cigars, cigarettes, candy, sandwiches?" she asked cheerfully.

Davis was back at the task of measuring the angle subtended by the patch
of shining sea, and then closely estimating its distance from the
_Esperance_. He said, "It _is_ smaller. Eleven hundred yards, now."

"When _La Rubia_ was here today," said Terry, "it might have been a
couple of miles across. Even that would be a terrific concentration of
fish! They're not all at the surface."

Davis said with impatience, seemingly directed against himself, "It's
narrowed two hundred yards in the past half-hour. It must be tending
toward something! There has to be a conclusion to it! Something must be
about to happen!"

Deirdre said slowly, "If it's the equivalent of a seine being hauled,
with a hum instead of a net, what's going to happen when it's time for
the fish to be boated?"

Davis ignored her for a moment. Then he said irritably, "Everyone seems
to have more brains than I do! Tony, break out those gun-cameras. Nick,
get back and report if the bright spot's getting any smaller. I wish you
weren't here, Deirdre!"

The two crew-cuts moved to obey. Terry, alone, had no specific duty
assigned to him on the yacht, unless tending to the recorder was it. He
bent over the instrument which was playing in the air anything that a
trailing microphone picked up under water. He raised the volume a
trifle. He could still hear the singular noises of the agitated fish
mixed in with the thin, strangely offensive humming sound. He heard
small thumpings, and realized that they were the footfalls of his
companions on the deck of the _Esperance_, transmitted to the water. He
heard ...

Tony came abovedecks with an armful of mysterious-looking objects which
could not be seen quite clearly in the slanting moonlight. He put two of
them down by the wheel and passed out the others. He silently left one
for Terry and another for Deirdre, while Terry adjusted tone and volume
on the recorder for maximum clarity.

"What are those?" asked Terry.

"Cameras," said Deirdre. "Mounted on rifle stocks, with flashbulbs in
the reflectors. You aim, pull the trigger, and the shutter opens as the
flashbulb goes off. So you get a picture of whatever you aim at, night
or day."

"Why ..."

"There was a time when my father thought they might be useful," said
Deirdre. "Then it looked like they wouldn't. Now it looks like they
may."

Terry was tempted to say, "Useful for what?" But Davis' vague talk of
unpleasant wrong guesses which led to even less pleasant ones had
already been an admission that no convincing answer could be given him.
Davis came over to him.

"This has me worried," he said in a frustrated tone of indecision. "We
must be near the end of some process that I didn't suspect, and the
conclusion of which I can't guess. I don't know what it is, and I don't
know what it's for. I only know what it's tied in with."

Terry said absorbedly, "Two or three times I've picked up some new kinds
of sounds. You might call them mooing noises. They're very faint, as if
they were far away, and there are long intervals between them. I don't
think they come from the surface."

Davis made an irresolute gesture. He seemed to hesitate over something
he was inclined to accept. Deirdre protested before he could speak. "I
don't think what you're thinking is right!" she said firmly. "Not a bit
of it! Whatever happens will be connected with the fish. _La Rubia_ has
been around this sort of thing over and over again! We haven't been
running the engine and we haven't been making any specific noises in the
water to arouse curiosity! If anything were going to happen to us, it
would have happened to _La Rubia_ before now! It would be ridiculous to
run away just because I'm on board!"

Terry, bent intently over the recorder, suddenly felt a cold chill run
up and down his spine. His mind told him it was ridiculous to associate
distant mooing sounds, underwater, with a completely unprecedented,
frantic gathering of fish into one small area, and come up with the
thought that something monstrous and plaintive was coming blindly to
feed upon fellow creatures of the sea. There was nothing to justify the
thought. It was out of all reason. But his spine crawled, just the same.

"The circle's only eight hundred yards across, now," said Davis,
uneasily. "The fish can't crowd together any closer! But Doug went
overboard with diving goggles, and he says there's a column of
brightness as far down as he can make out."

Terry looked up.

"He went overboard? Didn't he tingle?"

"He said it was like baby nettles all over," Davis protested, as if it
were someone's fault. "But he didn't sting after he came out. It must
be ..."

A mooing sound came out of the recorder. It was fainter than the other
sounds and very far away. It must have been of terrific volume where it
originated. It lasted for many seconds, then stopped.

"I should have been recording," said Terry. "That sound comes up about
every five minutes. I'll catch it next time."

Davis went away, as if he wanted to miss the noise and the decision it
would force upon him. Yet Terry told himself obstinately that there was
no reason to connect the mooing sound with the crazed fish herd half a
mile away. But somehow he couldn't help thinking there might be a
connection.

The ship's clock sounded seven bells. Deirdre said, "The brightness is
really smaller now!" The patch of flashes was no more than half its
original size. Terry pressed the recording button and straightened up to
look more closely. Right then Deirdre said sharply, "Listen!"

Something new and quite unlike the mooing noise now came out of the
recorder.

"Get your father," commanded Terry. "Something's coming from somewhere!"

Deirdre ran across the heaving deck. Terry shifted position so he could
manipulate the microphone hanging over the yacht's side into the water.
Davis arrived. His voice was suddenly strained and grim. "Something's
coming?" he demanded. "Can you hear any engine noise?"

"Listen to it," said Terry. "I'm trying to get its bearing."

He turned the wire by which the submarine ear hung from the rail. The
chirpings and squealings and squeakings changed volume as the microphone
turned. But the new sound, of something rushing at high speed through
the water--that did not change. Terry rotated the mike through a full
circle. The fish noises dwindled to almost nothing, and then increased
again. The volume of the steady hum changed with them. But the rushing
sound remained steady. Rather, it grew in loudness, as if approaching.
But the directional microphone didn't register any difference, whether
it received sound from the north, east, south, or west.

It was a booming sound. It was a rushing sound. It was the sound of an
object moving at terrific speed through the water. There was no engine
noise, but something thrust furiously through the sea, and the sound
grew louder and louder.

"It's not coming from any compass course," said Terry shortly. "How deep
is the water here?"

"We're just over the edge of the Luzon Deep," said Davis. "Four thousand
fathoms. Five. Maybe six."

"Then it can only be coming from one direction," said Terry. "It's
coming from below. And it's coming up."

For three heartbeats Davis stood perfectly still. Then he said, with
extreme grimness, "Since you mention it, that would be where it's coming
from."

He turned away and shouted a few orders. The crewmen scurried swiftly.
The yacht's head fell away from the wind. Terry listened again to the
rushing sound. There seemed to be regular throbbings in it, but still no
engine noise. It was a steady drone.

"Bazooka shells ought to discourage anything," Davis said in an icy
voice. "If it attacks, let go at it. But try to use the gun-cameras
first."

The _Esperance_ rolled and wallowed. Her bows lifted and fell. Her sails
were black against the starry sky overhead. Two of the crew-cuts settled
themselves at the starboard rail. They had long tubes in their hands,
tubes whose details could not be seen. The wind hummed and thuttered in
the rigging. Reef-points pattered. Near the port rail the recorder
poured out the amplified sounds its microphone picked up from the sea.
The sound of the coming thing became louder than all the other noises
combined. It was literally a booming noise. The water started to bubble
furiously as it parted to let something rise to the surface from
unthinkable depths.

Doug put two magazine-rifles beside Terry and Deirdre, then he moved
away. Deirdre had a clumsy object in her hands. It had a rifle-stock and
a trigger. What should have been the barrel was huge--six inches or more
in diameter--but very short. That was the flashbulb reflector. The
actual camera was small and on top, like a sight.

"We'll aim these at anything we see," said Deirdre composedly, "and pull
the trigger. Then we'll pick up the real rifles and see if we must
shoot. Is that all right?"

She faced the shining patch of ocean. Davis and the crew-cut at the
wheel faced that way. Tony and Jug stood with the clumsy tubes of
bazookas facing the same direction. Doug had taken a post forward, with
a camera-gun and a magazine rifle. He had the camera in hand, to use
first.

It seemed that hours passed, but it must have been just a few minutes.
Nothing out of the ordinary seemed to be taking place anywhere. The moon
now shone down from a sky in which a few thin wisps of cloud glowed
among the stars. Sharp-peaked waves came from one horizon and sped
busily toward the other. The yacht pitched and rolled, its company
strangely armed and expectant. The recorder gave out a droning, booming,
rushing sound which grew louder with ever-increasing rapidity. Now the
sound reached a climax.

From the very center of the glinting circle of sea, there was a
monstrous splashing sound. A phosphorescent column rose furiously from
the waves. It leaped. Water fell back and ... something soared into the
air. Sharp, stabbing flashes of almost intolerably white light flared
up. The gun-cameras fired their flashbulbs without a sound.

It was then that Terry saw it--in mid-air. He swung the gun-camera, and
a flash from another gun showed him that he would miss. He jerked the
gun to bear and pulled the trigger. The flash illuminated _it_ vividly.
Then night again.

It was torpedo-shaped and excessively slender but very long. It could
have been a living thing, frozen by the instantaneous flash. It could
have been something made of metal. It leaped a full fifty feet clear of
the waves and then tumbled back into the ocean with a colossal splash.
Then there was silence, except for the sounds of the sea. Terry had the
magazine-rifle still in his hands. Tony and Jug waited with their
bazookas ready. It occurred to Terry that yachts are not customarily
armed with bazookas.

"That--wasn't a whale," said Deirdre unsteadily.

The recorder bellowed suddenly. It was the hum that had been heard
before: the nasty, sixty-cycle hum that surrounded the captive fish. But
it was ten, twenty, fifty times as loud as before.

The fish in the bright-sea area went mad. The entire surface whipped
itself to spray, as fish leaped frenziedly to get out of the water,
which stung and burned where it touched.

Then, very strangely, the splashing stopped. The brightness of the sea
decreased. A while later the enormous snarling sound was noticeably less
loud than it had been at that first horrible moment.

The wind blew. The waves raced. The _Esperance's_ bow lifted and dipped.
The noise from the loudspeaker system--the noise from the sea--decreased
even more. One could hear the squeakings and chitterings of fish again.
But they were very much fainter. Presently the humming was no louder
than before the strange apparition. By that time the fish-sound had died
away altogether. The nearer normal noises remained. The hum was
receding. Downward.

Davis came to Terry, where he stood by the recording instrument.

"The fish have gone," he said in a flat voice, "they've gone away. They
didn't scatter. We'd have seen it. Do you realize where they went?"

Terry nodded.

"Straight down. Do you want to hear an impossible explanation?"

"I've thought of several," said Davis.

Doug came and picked up the gun-cameras that Terry and Deirdre had used
and went away with them.

"There's a kind of sound," said Terry, "that fish don't like. They won't
go where it is. They try to get away from it."

Deirdre said quietly, "I would too, if I were swimming."

"Sound," said Terry, "in water as in air, can be reflected and directed,
just as light can be. A megaphone turns out one's voice in a cone of
noise, like a reflector on a light. It should be possible to project it.
One can project a hollow cone of light. Why not a hollow cone of sound,
in water?"

Davis said with an unconvincingly ironic and skeptical air, "Indeed, why
not?"

"If such a thing were done," said Terry, "then when the cone of sound
was turned on, the fish inside it would be captured as if by a conical
net. They couldn't swim through the walls of sound. And then one can
imagine the cone made smaller; the walls drawn closer together. The fish
would be crowded together in what was increasingly like a vertical,
conical net, but with walls of unbearable noise instead of cord. It
would be as if the sea were electrified and the fish were shocked when
they tried to pass a given spot."

"Preposterous, of course," said Davis. But his tone was not at all
unbelieving.

"Then suppose something were sent up to the top of the cone, and it
projected some kind of a cover of sound on the top of the cone and
imprisoned the fish with a lid of sound they couldn't endure. And then
suppose that thing sank into the water again. The fish couldn't swim
through the walls of noise around them. They couldn't swim through the
lid of sound above them. They'd have to swim downward, just as if a hood
were closing on them from above."

"Very neat," said Davis. "But of course you don't believe anything of
the sort."

"I can't imagine what would produce that sound in that way and send up a
cork of sound to take the fish below. And I can't imagine why it would
be done. So I can't say I believe it."

Davis said slowly, "I think we begin to understand each other. We'll
stay as close to this place as we can until dawn, when we will find
nothing to show that anything out of the ordinary happened here."

"Still less," said Terry, "to hint at its meaning. I've been doing sums
in my head. That bright water was almost solid with fish. I'd say there
was at least a pound of fish to every cubic foot of sea."

"An underestimate," said Davis judicially.

"When the bright patch was a thousand yards across--and it was even
more--there'd have been four hundred tons of fish in the top three-foot
layer."

Davis seemed to start. But it was true. Terry added, "The water was
clear. We could see that the packing went on down a long way. Say fifty
yards at least."

"Y-yes," agreed Davis. "All of that."

"So in the top fifty yards, at one time, there were at least twenty
thousand tons of fish gathered together. Probably very much more. What
_La Rubia_ carried away couldn't be noticed. All those thousands of tons
of fish were pushed straight down. Tell me," said Terry, "what would be
the point in all those fish being dragged to the bottom? I can't ask who
or what did it, or even why. I'm asking, what results from it?"

Davis grunted.

"My mind stalls on who or what and why. And I'd rather not mention my
guesses. I.... No!"

He moved abruptly away.

The _Esperance_ remained under sail near the patch of sea that had
glittered earlier and now looked exactly like any other square mile of
ocean. The recorder verified the position by giving out, faintly, the
same unpleasant humming noise, either louder or fainter. A soft warm
wind blew across the waters. The land was somewhere below the horizon.
The reel of recorder-tape ran out. It was notable that there were very
few fish sounds to be heard, now. Very few. But the hum continued.

Toward morning it stopped abruptly. Then there was nothing out of the
ordinary to be observed anywhere.

The sun rose in magnificent colorings. The sky was clear of clouds.
Again the waves looked like living, leaping, joyous things. Gulls were
squawking.

Doug came up from belowdecks. He carried some photographic prints in his
hand. He'd developed and printed what the gun-cameras had photographed
when the mysterious object, or beast, leaped clear of the sea. There
were seven different pictures. Four showed flashbulb-lighted sections of
empty ocean. One showed a column of sea water rising at fantastic height
from the sea. Another one showed the edge of something at the very edge
of the film.

The seventh picture Terry recognized. It was what he'd seen when the
flashbulb of his gun-camera went off. The focus was not sharp. But it
was neither a whale nor a blackfish--not even a small one--nor was it a
shark. It was not a squid. It was not even a giant manta. The picture
was a blurry representation of something unreal made for an unimaginable
purpose, under abnormal conditions.

Deirdre looked at it over his shoulder. It could be a living creature.
It could be ... anything.

"You said you didn't like mysteries," commented Deirdre. "Are you sorry
you came?"




_Four_


The next morning the _Esperance_ headed southeast over a sunlit sea.
First, of course, the crew examined the sea's surface for miles around.
As expected, there was nothing remarkable to be observed. Davis did
point out that there were no fish jumping, which was an indication that
there were not as many fish as usual in this part of the ocean. But it
was hard to be sure. There is no normal number of times when fish will
be seen to jump. They usually jump to escape larger fish that want to
eat them. The number is pure chance. But there seemed to be almost no
jumps at all this morning.

It was not discussed at length, however. All the ship's company was
curiously reluctant to refer to the events of the previous night. In
broad daylight, a detached review was simply impractical. With gulls
squawking all about, with seas glinting in the sunshine, with decks to
be washed and breakfast to be eaten, and commonplace, routine
ship-keeping to be done, the adventure of the patch of shining sea
seemed highly improbable. Terry felt that it couldn't really have
happened. To discuss it seriously would be like a daylight ghost tale.
One was unable to believe it in daylight. It was better ignored.

Terry, though, did get out his tools to make a minor modification in the
underwater microphone. It had been designed to be directional, so that
the sound of surf or fish could be located by turning the mike, but he
hadn't been able to point it vertically downward, and last night that
had been the key direction--right under the yacht's keel. So now he
improvised gimbals for the microphone, and a mounting for it similar to
that of a compass, so it could tilt in any desired direction, as well as
turn.

Which, of course, was a tacit admission that something peculiar had
happened. Presently, Deirdre came and watched him.

"What's that for?" she asked, when he fitted the gimbals in place.

He told her. She said hesitantly, "Yesterday, when I asked you not to
try the paddle until we got to shallow water, you got angry and said
you'd ask to be put ashore. We're headed for Barca now. Someone there is
building something for my father, the same thing I had asked you to
build--a fish-driving instrument. If you still want to go, you can get a
bus from there to Manila. But I hope you have changed your mind."

"I have," said Terry dourly. "I told your father so. I was irritated
because I couldn't get any answers to the questions I asked. Now I've
got some questions your father wants answers to. And I'm going to try to
find them out."

Deirdre sighed, perhaps in relief.

"I put some pictures and a clipping in a book on the cabin table," she
said. "Did you see them?"

He nodded.

"What did you think?"

"That you put them for me to see," he said.

"It was to make you realize that we can't answer every question, which
you know now."

"I still think you could answer a few more than you have," he observed.
"But let it go. Is the Barca harbor shallow?"

"Ten, fifteen feet at low tide," she informed him. "We're having a sort
of dredge made there. Something to go down into the sea, take pictures,
get samples of the bottom, and then come up again. There's an
oceanographic ship due in Manila shortly, by the way. It will have a
bathyscaphe on board. Maybe that will help find out some answers." Then
she said uncomfortably, "I have a feeling the bathyscaphe isn't ...
safe."

He glanced up.

"_Ellos?_" He grinned as she looked sharply at him. Then he said, "This
dredge: isn't it pretty ambitious for a boat this size to try to dredge
some thousands of fathoms down?"

"It's a free dredge," she said. "It will sink by itself and come up by
itself. There's no cable. What are you doing now?"

He'd put away the submarine microphone he'd just altered and was now
taking out the still untested underwater horn.

"I'm going to try to make this directional, too," he said. "In fact, I'm
going to try to make it project sound in a beam shaped like a fan. A
hollow cone may come later."

She was silent. The _Esperance_ sailed on.

"Ever talk to the skipper of _La Rubia_?" he asked presently.

She shook her head.

"You should. He's a stupendous, self-confident liar," said Terry. "He
lies automatically. Gratuitously. A completely amiable man, but he can't
tell the truth without stopping to think."

"We found that out," said Deirdre. "I didn't. Someone else."

"Is this another censored subject, or can I ask what happened?"

"I'd better see about lunch," said Deirdre quickly.

She got up and left. Terry shrugged. The day before yesterday, or even
yesterday, he'd have been indignant. But then he'd known these people
had secrets in which he had no share. Today he was beginning to share
those secrets, and he had fabulously nonsensical material on which to
work on his own. He had strange ideas about the event of last night. He
did not quite believe them, but he thought he had devised some ways to
see how much of truth they contained, if any. Deirdre could keep her
secrets, so long as he did not have to disclose his own wildly
imaginative ideas.

The routine of the yacht went on. It was in a way a very casual routine.
Davis gave orders when the need arose, but there was no formal
discipline; there was co-operation. Terry heard one of the crew-cuts ask
Deirdre a question using her first name. It would have been highly
improbable in a paid crew, but it was reasonable enough in a volunteer
expedition. He heard Deirdre say, "Why don't you ask him?"

The crew-cut, Tony, came to the part of the deck where Terry worked.

"We got into an argument," he said without preface. "We were talking
about that ... 'whale' last night."

Terry nodded. The use of the term "whale" was a deliberate pretense that
the previous night's events were natural and normal.

"How fast do you think it was traveling when it broached?" asked Tony.
"I know a whale can jump clear of the water. I've seen it in the movies.
But that one jumped awfully high!"

"I hadn't tried to estimate it," said Terry.

"You've got a tape of the noise," said Tony. "Could you time the
interval between the sound when it left the water, and the splash when
it fell back?"

"Mmm. Yes," said Terry. He looked up. "Of course."

"It would be interesting to do it," said Tony, semicasually. Then he
added hastily, "I've read somewhere that whales have been clocked at
pretty high speeds. If we can find out how long its leap lasted, we
could know how fast it was going."

Terry considered for a moment, and then got out the recorder. He played
the tape for a moment, and skipped forward to later parts of the record
until he came to the place where the unpleasant humming sound was loud,
and finally reached the beginning of the rushing noise. That, in turn,
had preceded the leap of the object photographed by the gun-cameras.

Terry glanced at his watch when the rushing started. He timed the period
of ascent of the noise, while it grew louder and louder and became a
booming sound, which was at its loudest the instant before it ceased. At
that moment the mysterious object had leaped out of the sea. The splash
of its re-entry came long seconds later.

Tony timed the leap. When the splash came he made his calculations
absorbedly, while Terry switched off the recorder.

"It would take the same amount of time going up as it does coming down,"
said Tony, scribbling numbers. "Since we know how fast things fall, when
we know how long they fall we can tell how fast they were traveling when
they landed, and therefore when they leaped."

He multiplied and divided.

"Sixty miles an hour, roughly," he pronounced. "The whale was going
sixty miles an hour straight up when it left the water! What can swim
that fast?"

"That's your question," said Terry. "Here's one of mine. We heard it
coming for five minutes ten seconds. How deep is the water where we
were?"

"About forty-five hundred fathoms."

"If we assume that it came from the bottom, it must have been traveling
at least sixty miles an hour when it broke surface," said Terry.

"But can a whale swim sixty miles an hour?"

"No," said Terry.

Tony hesitated, opened his mouth, closed it, and went away.

Terry returned to the changing of the submarine horn. Sound has its own
tricks underwater. If you know something about them you can produce some
remarkable results. A deliberately made underwater signal can be heard
through an unbelievable number of thousands of miles of seawater. But,
except through a yet untested fish-driving paddle, Terry had never heard
of fish being herded by sound. Still, fish can be stunned or killed by
concussions. They have been known to be made unconscious by the noise
of a very near submarine bell. It wasn't unreasonable that a specific
loud noise could make a barrier no fish would try to cross. But there
were still some parts of last night's events that did not fit into any
rational explanation.

Davis came over to Terry.

"I think," he said, "that we may have missed a lot of information by not
having submarine ears before. There may have been all sorts of noises we
could have heard."

"Possibly," agreed Terry.

"We're more or less in the position of savages faced with phenomena they
don't understand," said Davis vexedly. "The simple problems of savages
range from what produces thunder to what makes people die of disease.
Savages come up with ideas of gods or devils doing such things for
reasons of their own. We can't accept ideas of that sort, of course!"

"No," agreed Terry, "we can't."

"But what happened last night," said Davis, "is almost as mysterious to
us as thunder to a savage. A savage would blame it on devils or
whatnot."

"Or on _ellos_," said Terry.

"He'd imagine a personality behind it, yes," said Davis. "He does things
because he wants to, so he thinks all natural phenomena occur because
somebody wants them to. He has no idea of natural law, so he tries to
imagine what kind of person--what kind of god or devil--does the things
he notices. It's a natural way to think."

"Very likely," admitted Terry. "But the point?"

"Is that we mustn't fall into a savage's way of thinking about last
night's affair."

Terry said, "I couldn't agree with you more. But just what are you
driving at?"

"There's a dredge being made for me in Barca. I'm afraid you may suspect
that I'm trying to--stir up something with it. To poke something we
_know_ is somewhere but can't identify. I didn't want you to try the
fish-paddle in deep water, that's true. But...."

"You're explaining," said Terry, "that you didn't want me to whack a
fish-driving paddle overside in deep water."

Davis hesitated, and then nodded.

"The phenomena you're interested in are under water?"

"Yes," said Davis. "They are in the Luzon Deep area."

"Then, to be co-operative, I'll test this contrivance in ten to fifteen
feet of water in the Barca harbor. And I will not get temperamental
about your suggestions that I should not mess up your deep-water
inquiries."

"Thanks," said Davis.

He went forward to meet Nick, just coming abovedecks with a slip of
paper in his hand. It occurred to Terry, suddenly, that somebody went
below down the forecastle hatch just about every hour on the hour. They
must be in short-wave communication with Manila. It had been mentioned
last night--a loran fix on the _Esperance's_ position. There were
apparently frequent reports to somebody somewhere.

The afternoon went by. A tree-lined shore appeared to the eastward just
when the gaudy colorings of a beautiful sunset filled all the western
sky. The _Esperance_ changed course and followed the coast line, some
miles out. Night fell. The yacht sailed with a fine smooth motion over
the ocean swells.

After dinner Davis was below, fiddling with the knobs to pick up
short-wave music from San Francisco, and the muted sound of an argument
came occasionally from the forecastle where the four crew-cuts resided.
Terry and Deirdre went on deck.

"My father," said Deirdre, "says you understand each other better, now.
He doesn't think you're going to feel offended with us, and he's really
pleased. He says your mind doesn't work like his, but you come to more
or less the same conclusions, which makes it likely the conclusions are
right."

Terry grimaced.

"My conclusion," he observed, "is that I haven't enough facts yet to
come to any conclusion."

"Of course!" said Deirdre. "Just like my father!"

They sat in silence. It was not exactly a tranquil stillness. It was
pleasant enough to be here on the slanting deck of a beautiful yacht,
driving competently through dark seas under a canopy of stars. But now
Terry realized he was constantly aware of Deirdre. He liked her. But
he'd liked other people, male and female, without being continually
conscious of their existence. Girls are usually more conscious of such
things than men. At least ninety-nine per cent of the time, a man does
not modify his behavior because of the age, sex, and marital status of
the people he comes in contact with. It isn't relevant to most of what
he says and does. But a girl frequently modifies her actions in just
such circumstances. Deirdre was well aware of the slightly uneasy,
extremely interested state of Terry's mind. There was silence for a long
time. Then a shooting star went across the sky. It went out.

"Would you like to hear something really wild?" asked Deirdre, ruefully.
"That shooting star, just then. It used to be true that more
meteorites--shooting stars--had fallen and been recovered in Kansas than
any other place in the world. But it would be ridiculous to think they
aimed for Kansas, wouldn't it?"

Terry nodded, not following at all.

"At Thrawn Island," said Deirdre, "since the satellite-tracking station
has been built, space-radars have picked up more bolides--big
meteors--coming in to fall in the Luzon Deep than ever in Kansas or
anywhere else. I think my father frets over that, simply because he's so
concerned about the Luzon Deep."

Terry heard himself saying irrelevantly, "I'd like to ask you a few
strictly personal questions, Deirdre. What's your favorite food? What
music do you like? Where would you like best to live? When...."

Deirdre turned her head to smile at him.

"I've been wondering," she said, "if you thought of me only as a fellow
researcher or whether you'd noticed that I'm a person, too. Hmmmmm.
There's a restaurant in Manila where they still cut their steaks along
the muscle instead of across it, but where they make some unheard-of
dishes. That place has some of my favorite foods. And...."

"Next time we're in Manila we'll try it," said Terry. "Now, I know a
place...."

The _Esperance_ went on. Presently, the moon rose and moonlight glinted
on the waves while the stars looked cynically down on the small yacht
upon the sea. And two people talked comfortably and absorbedly about
things nobody else would have thought very interesting.

When Terry turned in for the night he realized pleasantly that he was
very glad he'd let himself be persuaded to join the _Esperance's_
company.

Dawn came. Terry was already on deck when the _Esperance_ threaded her
way into a small harbor. There were palm trees along the shore, and
there was a Philippine town with edifices ranging from burnt brick to
stucco to mere nipa huts on its outskirts. Two-man fishing boats were
making their way out from the shore on which they'd been beached. From
somewhere came the staccato, back-firing noise of an old
automobile-engine being warmed up for the day's work. It would
undoubtedly be the bus for Manila. But it was not thinkable that Terry
should take it, now.

The yacht dropped anchor and lay indolently at rest while her crew
breakfasted and the morning deck routine was being performed. Then
Deirdre appeared in shore-going clothes of extreme femininity. Davis too
was dressed otherwise than as usual.

"We're going ashore to the shipyard," he told Terry. "If you'd like to
come--"

"I've something to do here," said Terry.

Two of the crew-cuts got a boat overside and headed it for the shore.
Terry got out the recorder and the submarine ear and horn. He set up his
apparatus for a test. Tony came from belowdecks and watched. Then he
came closer.

"If I can help," he said tentatively.

"You can," Terry told him. "But let's listen to what the fish are
saying, first."

He dropped over the submarine ear and started the recorder to play what
it picked up, but without recording it. Sounds from underwater came out
of the speakers. The slappings of tiny harbor-waves against the yacht's
planking; the chunking, rhythmic sound of oars from a fishing boat which
was rowing after the half-dozen that had gone out earlier; grunting
sounds. Those were fish.

Terry listened critically, and Tony with interest. Then Terry brought
out the fish-driving paddle. He turned on the tape, now, to have a
record of the sound the paddle made.

"Whack this on the water," he suggested, "and we'll hear how it sounds."

Tony went down the ladder and gave the water surface a few resounding
whacks. There were tiny, violent swirlings. For thirty or forty feet
from the _Esperance's_ side there were isolated, minute turmoils in the
water. Three or four fish actually leaped clear of the surface.

"Not bad!" said Tony. "Shall I whack some more?"

Terry reeled back a few feet of the tape which contained the whacking
sounds. He re-played them, listening critically as before. Tony had
returned to the deck. The whackings, as heard underwater, were not
merely impacts. There was a resonance to them. Almost a hum. Rather
grimly, Terry substituted this tape-reel with the recording he'd made
the night before. He started the instrument and found the exact spot
where the object from the depths had fallen back into the sea. He
stopped the recorder right there. He hauled up the submarine ear and
plugged in the horn to the audio-amplifier, as yet untested, which
should multiply the volume of sound from the tape. Then he put the horn
overside.

He switched on the recorder again. The tape-reel began to spin. The
sound went out underwater from the horn. Underwater it was much louder
than when it had been received by the _Esperance's_ microphone. Here it
was confined by the surface above and the harbor-bottom beneath. It must
have been the equivalent of a loud shout in a closed room--only worse.

The fish in the harbor of Barca went mad. All the harbor-surface turned
to spray. Creatures of all sizes leaped crazily above the surface, their
fins flapping, only to leap again, more frantically still, when they
fell back. A totally unsuspected school of very small flying fish
flashed upward in such frenzied haste that some tried to climb too
steeply and fell back and instantly flung themselves into the air again.

Terry turned off the playing recorder. The disorder at the top of the
water ceased immediately. But he heard shrill outcries. Children had
been wading at the edge of the shore. They stampeded for solid ground,
shrieking. Where their feet and legs had been underwater they felt as if
a million pins and needles had pricked them.

Something flapped heavily on the _Esperance's_ deck. Tony went to see.
It was a three-pound fish which had leaped clear of the water and over
the yacht's rail to the deck.

Tony threw it back into the water.

"I guess there's not much doubt," he said painfully.

"Of what?" demanded Terry.

"Of what ... I had guessed," said Tony.

"And what did you guess?"

Tony hesitated.

"I guess," he said unhappily, "that I'd better not say."

He watched with a startled, uneasy expression on his face as Tony put
the apparatus away.

Time passed. Davis and Deirdre had been ashore over an hour. Then Terry
saw the small boat leave the shore and approach. It came deftly
alongside, the two passengers climbed up to the deck, and all four
crew-cuts hauled the boat back inboard and lashed it fast.

"Our dredge isn't ready yet," said Davis. "It looks good, but there'll
be a delay of a few days."

Deirdre examined Terry's expression.

"Something's happened. What?"

Terry told her. Davis listened. Tony added what he'd seen, including the
fish that had leaped high enough out of the water to land on the
_Esperance's_ deck.

"After the fact," said Davis, "I can see how it could happen. But...."
He hesitated for a long time and then said, "This is another case where
I've been making guesses and hoping I was wrong. And like the others,
proof that my early guess was wrong makes another guess necessary. And I
dislike the later guess much more than the first."

He moved restlessly.

"I'm glad you only tried it once, here," he said unhappily. "We're due
up at Thrawn Island anyhow. You can work this trick out in the lagoon up
there. If there's no reaction to the dredge when we try it, we can try
this. But it might be a very violent poke at something we don't quite
believe in. I'd rather try a gentle poke first."

He turned away. In minutes Nick was belowdecks starting the yacht's
engine, two others of the crew-cuts were hauling up the anchor, and the
fourth was at the wheel. Without haste, but with celerity, the
_Esperance_ headed for the harbor-mouth and the open sea.

They had their midday meal heading north by west. Late in the afternoon
Deirdre found occasion to talk to Terry about Thrawn Island.

"It's the China Sea tracking station for satellites," she told him.
"Some of the staff are friends of my father's. It's right on the edge of
the Luzon Deep, and the island's actually an underwater mountain that
just barely protrudes above the surface. There are some hills, a coral
reef and a lagoon. It's also terrifically steep, and you can use the
fish-driving device as much as you please without startling any Filipino
fishermen."

"You've been there before," said Terry.

"Oh, yes! I told you a fish wearing a plastic object was caught in the
lagoon there. That was when the station was being built. The men at the
tracking station fish in the lagoon for fun, and now they're naturally
watching out for more ... oddities."

The _Esperance_ sailed on. The crew-cuts went about their various chores
and talked endlessly, among themselves and with Deirdre, when she joined
in. Terry felt useless. He trailed the submarine ear overboard and set
the recorder to work as an amplifier only. At low volume it played the
sounds of things below. He kept half an ear cocked toward it for the
mooing sound he'd picked up at the place where the ocean glittered. He
heard it again now, and again found it difficult to imagine any cause
for it. The sounds uttered by noisemaking fish are usually produced in
their swim-bladders. The purpose of fish cries is as obscure as the
reason for some insect stridulations, or the song of many birds. But a
long-continued fish noise would involve a swim-bladder of large size. At
great depths, if a considerable cavity were filled with gas, under
pressures running into tons to the square inch.... Terry could not
quite believe it.

He did not hear the mooing sound any more, as the yacht went on its way.
Other underwater sounds became commonplace, and he tended not to hear
them. From the deck around him, though, he heard arguments about wave
mechanics, prospects in the World Series, the virtues of Dixieland jazz,
ichthyology, Copeland's contribution to modern music, the possibility of
life on other planets, and kindred topics. The crew-cuts were taking
their summer vacations as able seamen on board the _Esperance_, but they
had as many and as voluble opinions as any other undergraduates. They
aired them on each other.

The afternoon passed. Night fell, and dinner was a session of learned
discussion of different subjects, always vehemently argued. Later Terry
took the yacht's wheel, Deirdre sat comfortably nearby, and they
discussed matters suitable to their more mature status. They were much
less intellectual than the crew-cuts. In a few days they developed an
interest in each other, but each of them believed this was just a very
pleasant friendship.

Eventually, the moon rose. It was close to midnight when Nick bobbed
belowdecks and came up with a report that they'd been picked up by the
Thrawn Island radar and were proceeding exactly on course. Half an hour
later a tiny light appeared at the edge of the sea. The _Esperance_
headed for it, and presently there were breakers to port and starboard,
the engine rumbled, down below, and the yacht lifted and fell more
violently than ordinary. Then once more she was in glassy-smooth water;
the air was very heavy with the smell of green vegetation. Certain
rectangles of light became visible. They were the windows of the Thrawn
Island satellite-tracking installation.

The _Esperance's_ sails were lowered and she moved toward the lights on
engine power only. There was no movement ashore, though Nick had talked
with the island on short-wave.

After a little while the searchlight was put in operation and began to
reach out like a pencil of brilliant white light. It darted here and
there and found a wharf reaching out from the shore to deep water. The
_Esperance_ floated toward it, her engine barely turning over. There was
still no sign of activity, except for the lighted windows.

The engine stopped, then reversed, and the yacht drifted gently until it
contacted the wharfs snubber-pilings. Jug and Tony jumped ashore with
lines to fasten the yacht. Still no sign of life.

"Queer," said Davis, staring ashore. "They knew we were coming!"

A moving light suddenly appeared in the sky. A fireball, which is an
unusually lurid type of shooting star. It came over the tree-tops and
crossed the zenith, leaving a trail of light behind it. It went on and
on, seemingly slowing down, which meant that it was descending from a
very high altitude. Its brilliance became more and more intense, then it
dimmed. At this point the fireball seemed to plunge downward. Then its
flame went out and only a faint, dull-red speck in motion could be seen.

It plunged down beyond the trees on the far side of the lagoon. Or so it
seemed. Actually, it might have plunged into the sea, miles away. Then
there was a faint noise which was something between a rumble and a hiss.
The sound went back across the sky along the path the fireball had
followed. It died away.

There was silence. Shooting stars as bright as this one are rare. Most
meteors are very small, but they are visible because of the attrition
produced by their falling bodies in the atmosphere that sets them on
fire. They usually appear at around a seventy-mile height, but
frequently they are vaporized before they have descended more than
thirty miles. Sometimes they explode in mid-air and strew the earth with
fragments. Sometimes they strike ground, leaving monstrous craters where
they have fallen. Most meteors fall in the sea. But a meteor has to be
at least down to twenty miles from sea level before its sound can be
heard.

Someone came out of a building and moved toward the wharf, an electric
lantern bobbing in his hand. Halfway out to the yacht he called,
"Davis?"

"Yes," said Davis. "What's happened?"

"Nothing," said the man ashore. "We were watching for that bolide. It
was picked up by space radar a couple of hours ago, but then we figured
it to land farther on than it did."

It was an educated voice, a scholarly voice.

"Big?" asked Davis as the light drew nearer.

"We've seen them bigger, but not much." The man with the lantern reached
the end of the wharf. "Glad to see you. We've got some fish for you, by
the way. We caught them in the lagoon. They're waiting for you in the
deep-freeze. There's a _Macrourus violaceus_, if we read the books
right, and a _Gonostoma polypus_. They match the pictures, anyhow. What
do you make of that?"

"You haven't got them!" said Davis incredulously. "You can't have them!
I'm no fish specialist, but those are abyssal fish! They can only be
caught at a depth of two or more miles!"

"We caught 'em," said the man cheerfully, "on a hook and line, in the
lagoon, at night. Come ashore! Everybody'll be glad to see you."

Davis protested, "I won't believe you've got that kind of fish until I
see them!"

The man with the lantern stepped down to the yacht's deck.

"All you've got to do is look in the mess hall deep-freeze. The cook's
complaining that they take up space. Nobody wants to find out if they're
good to eat. Most unwholesome-looking creatures! And how are you, young
lady?" he asked Deirdre. "We've missed you. Tony, Nick, Jug...."

Deirdre introduced Terry.

"Ha!" said the man. "They got you enlisted, eh? They were talking about
it a month ago. You've solved the problem by now, I daresay. Including
how these very queer fish happen to be in our lagoon instead of miles
down in the Luzon Deep. When you find time, tell me!"

"I'll try," said Terry reservedly.

The man went down into the after-cabin and Davis followed him. Deirdre
said amusedly:

"Dr. Morton's a dear! Don't take him seriously, Terry! He loves to
tease. He'll hound you to tell him how deep-sea fish got up here and
into a shallow lagoon. Please don't mind!"

"I won't," said Terry. "I'll tell him tomorrow, I think. I believe now I
know how it happened, but I want to check it first."




_Five_


When Terry awoke, next morning, the reflections of sunlight on water
came in through the porthole of his cabin. He watched the shimmering
contortions of the light spots on the wall. His thoughts went instantly
back to the subject they'd dwelt on before he went to sleep. The man
with the spectacles--Dr. Morton, but his doctorate was in astronomy
instead of medicine--had said that Deirdre and his father had discussed
enlisting him in the _Esperance's_ company a month ago. Deirdre'd come
into the shop of Jimenez y Cia. only four days before. Some of the delay
could have been caused by time spent in simple sailing from one place to
another, mostly on wholly futile errands. They'd gotten a fish-driving
paddle at Alua. That'd take some days of sailing each way. Apparently,
they'd been fumbling at some vague idea of trying to find out what would
produce the facts they'd noted. 'Very queer fish,' Davis had said of
some of the catches _La Rubia_ had made. The abyssal fish mentioned last
night would be very queer fish to catch in a lagoon. Yes....

He lay still, surveying other aspects of the situation. Davis had called
on an aircraft carrier for electronic items, and the _Esperance_ was in
constant touch with somebody by short-wave radio. It might be the same
carrier. The Manila police department was on very cordial terms with
Davis, and the staff of a satellite-tracking installation saved odd
specimens of fish for him.

The _Esperance's_ enterprise was plainly not a brand-new adventure. It
had been carried on for some time. They had had technical aid of the
very highest caliber, but they hadn't gotten anywhere yet. It did
appear that Terry had added a minor specialty to the arsenal of
investigative techniques. Without the data gathered on recorder-tape,
their idea of the events of two nights before would be very different.
The sea would have seemed very bright, then the glowing area would have
been noted to have grown smaller, and something resembling a whale would
have been seen leaping high above the water. Then the brightness would
have faded out. It would have been mysterious enough, but an entire
aspect of the phenomenon would have gone unnoticed. There was still no
answer to any of the far-reaching questions Terry had asked himself, but
most of them had never been asked before. Sea noises had proved to be
closely connected to whatever had to be found out. What was known about
them was due to his findings. He'd established a new frame of reference.

And he'd discovered the solution of a minor problem before the problem
was even stated. He had only to prove it. Then, of course, there would
be other problems arising from it.

He got up, put on swimming trunks, and duck trousers over them. He
slipped into a sweat shirt and went upon deck. Deirdre hailed him.

"Good morning! Everybody's over at the tracking station, arguing about
the bolide that went over last night. According to the radar, it plunged
into the sea, miles and miles away."

"What should it have done?" asked Terry. "I'm not familiar with
meteorites. Are they planning to dive for it?"

"Hardly!" Deirdre laughed. "It landed in the Luzon Deep." She waved a
hand in an inclusive gesture. "This island's on the brink of it. A
bathyscaphe might go down there--in fact, I think it's scheduled; you
know, the one I said was coming to Manila on the oceanographic ship? A
bathyscaphe can go that deep, but it's not likely to hunt for
meteorites."

"Ah," said Terry judicially. "Then what difference does it make where it
hit?"

"It didn't fall the way it should have," said Deirdre. "It was spotted
by space radar away out, and they tried to compute its path, but they
figured it wrong. Now they're trying to make it come out right by
allowing for the effect of the earth's magnetic field on a metal
meteorite. They're arguing and waving equations at each other."

"Let them," said Terry. "I have trouble enough with fish. Do you think I
could borrow a boat?"

"We've always been able to," said Deirdre. Then she added, "I've kept
your breakfast hot. While you eat it I'll get a boat."

She went below, and instants later was up again.

"I have a feeling," she said, "that something interesting is going to
happen. I'll be back."

She swung lightly to the wharf and headed for land. Terry went below, to
find his breakfast laid out on the cabin table. He settled down to it,
but first pulled a book from the shelves. It was a volume on
oceanography, and its pages showed that it had often been referred to.
He found the Luzon Deep described. Its area was relatively small, a mere
ninety-mile-long chasm in the sea-bed. But it was second only to the
Mindanao Deep in its soundings, and a close second at that. Its maximum
depth was measured at twenty-seven thousand feet. Over five miles. There
was a mention of Thrawn Island as being on the very edge of the Deep.
According to the book, the island was the peak of one of the most
precipitous and tallest submarine mountains in the world. Three miles
from where Thrawn Island lay, there were soundings of twenty-eight
thousand feet and upward. This depth extended as a trench....

The staccato roaring of an outboard motor sounded some distance away. It
bellowed toward the yacht, swung about, and cut off. Terry gulped down
his coffee and went abovedecks, just as Deirdre was fastening the small
craft alongside the yacht.

"Taxi?" she asked amiably. "I got the boat. Where to?"

Terry swung down and took the steering grip. He headed the boat away.
There was a box for bait, a few fishing lines, and even two highly
professional fish-spears on board. Fishing was not necessarily a
sedentary pastime here.

"We try the lagoon entrance," he said. "I've an idea. I noticed
something last night, when we came in."

"Do you want to brief me?"

"I'd rather not," he admitted.

Deirdre shrugged without resentment. The little craft went sturdily
toward the passageway to the open sea. She formed an arrowhead of waves
as she moved. She neared the points of land at the ends of the coral
formation enclosing the lagoon. Thrawn Island was not an atoll. But the
beaches were made of snow-white coral sand. Outside there was clear
water for a space and then a reef on which the seas broke.

Terry headed the boat toward the open sea. Almost immediately after,
there was nothing but the reef and the sea between the boat and the
horizon. He slowed the boat almost to a stop, well within the reef's
tumult. She swayed and rolled on the surging water.

"Stay here," he commanded. "I want to swim out and back."

He pulled the sweat shirt over his head. He jumped overboard, leaving
Deirdre in charge of the boat.

The world looked strange to him when waves rolled by higher than his
head. A few times the sky narrowed to the space between wave-crests.
Other times he was lifted upon a wave-peak, and the sky was illimitably
high and large, and the breaking seas on the nearby reef merely roared
and grumbled to themselves.

He swam out, away from the land. Suddenly his body began to tingle. He
stopped and paddled, analyzing the sensation. One side of his body felt
as if the most minute of electric currents entered his skin. It was not
an unpleasant sensation. Deirdre, in the small boat, was fifty yards
behind, watching him. As he swam on, the tingling grew stronger. He
dived. The tingling did not vary with depth. He came up, and he was
farther out than he'd realized.

He suddenly knew that he'd been incautious. There are currents which
flow in and out of lagoons. A barrier of reef affects them, too. Terry
found himself swimming in an outward-bound current, which pushed him out
and away from the island.

Within seconds the sensation in his body changed from a mere tingling
to torment. For a moment it was just very much stronger and slightly
painful, but a moment later it felt as if he swam among flames. It was
unbearable. His muscles were not contracted, as if by an electric shock,
but he couldn't control their reflexes. He found himself splashing
crazily, trying to fight his way out of the anguish which engulfed him.

He went under. His body had taken complete control over his mind, and he
found himself swimming frantically, underwater. He couldn't reach the
surface. His body tried to escape the intolerable agony in which it was
immersed but couldn't.

He heard a roaring sound, but it meant nothing. The roaring grew louder.
Finally, he did break surface for a few seconds, and he gasped horribly,
but then he went under. The roaring grew thunderous, and he broke
surface again....

Something seized his flailing arm and pulled him up. The arm ceased to
experience the horrible sensation of being in boiling oil. His hand
recognized a gunwale. He swarmed up the solid object with hands helping
him, and found himself in the boat, gasping and shivering, and cringing
at the bare memory of the suffering he'd undergone.

Deirdre stared at him, frightened. She swung the boat's bow shoreward.
The outboard motor roared, and the boat raced past the gap in the reef
and rushed toward the lagoon opening.

"Are you all right? What happened? You were swimming and suddenly...."

He swallowed. His hands quivered. He shook his head and then said
unsteadily, "I meant to ... check the reason those queer fish stay in
the lagoon. I thought that if they belonged in the depths and were
somehow carried out of them, they would try to get back. I found out!"

He felt an unreasonable relief when the lagoon entrance was behind the
boat. The glassy water was reassuring. The _Esperance_ looked like
safety itself.

"I think I know how they got here, now," he added. "We underestimated
what we're trying to understand. I'll be all right in a minute."

It was less than a minute before he shook himself and managed to grin
wryly at Deirdre.

"Was there a hum in the water?" asked Deirdre, still staring at him. "I
thought I heard it on the bottom of the boat. Was that the trouble?"

"Yes. I wouldn't call it a hum," Terry admitted. "Not any longer. Now I
know what a slow fire feels like."

"You frightened me," said Deirdre, "the way you splashed...."

"I heard the humming sound," said Terry, "last night when the yacht came
up to the island. We were perhaps a half-mile off-shore. It was very
faint, but I had the amplifier turned down low. The hum was at its
loudest just before we passed the reef, but nobody else noticed. When
Dr. Morton said there were abyssal fish in the lagoon, I knew why they'd
be there. I made a guess at what might drive them there. I went to find
out if I was right. I found out!"

"The hum?" asked Deirdre again. When he nodded, she said: "What are you
going to do now? What do you think makes the hum?"

"I'm trying hard not to guess what makes the hum," Terry told her.
"Insufficient data. I need more. I think I'll ask what other odd
phenomena have turned up in this neighborhood. Foam-patches on the sea?
I can't imagine a connection, but still...."

He swung the little boat alongside the docked _Esperance_ and held out
his hand to help Deirdre to the dock. His hand was wholly steady again.
She accepted the help.

"We'll go to the tracking station?"

"Yes. Everybody seems to be there," said Terry.

They heard a babble of voices coming from the satellite-tracking
station. As they approached the buildings, Terry looked around. Off at
one side there was the very peculiar aerial system by which tiny
artificial moons circling the earth could be detected by their own
signals. Minute spheres and cylinders and spiky objects and
foolish-looking paddle-wheels, whirling in their man-appointed rounds,
sent down signals with powers of mere fractions of a watt. This system
of aerials picked up those miniature broadcasts and extracted
remarkable amounts of information from them. It was possible to
determine the satellites' distance more accurately, by a comparison of
phase-changes in their signals, than if steel tape measures were
stretched up to make physical contact with them. The accuracy was of the
order of inches at hundreds of miles. Floating where the stars were
bright and unwinking lights against blackness and the sun was a disk
with writhing arms of fire, the small objects sent back information that
men had never possessed before and did not wholly know what to do with
now that they did. And there were other objects in the heavens, too.
There were satellites which no longer signaled back to earth. Some had
their equipment worn out. Some objects were satellites which had failed
to function from the beginning. Some were mysteries.

The bolide of the night before was a mystery. As Terry and Deirdre
entered the wide verandah of the recreation building for the station's
personnel, they heard Dr. Morton protesting, "But that's out of the
question! I agree that we never know any more about what the Russians
throw out to space than what we find out for ourselves. That's true! But
this wasn't a terrestrial object! If it was a satellite that wasn't
launched right, it had to be sent up from Russian territory. It wasn't.
That's positive! If we assume it was a satellite that had already made
several orbital turns, we must admit it would be an impossible shift in
apogee for it to come down at the angle it did!"

Deirdre and Terry sat down as someone else said hotly, "Our observations
were wrong. They had to be! The earth's magnetic field couldn't affect
the speed of an object _outside_ the atmosphere! Our observations say it
slowed down. It couldn't!"

Davis lifted a hand in greeting. The argument stopped for a moment.
Deirdre was known, but Terry had to be introduced. He was sitting beside
a bald young man who explained in a low tone, as the argument resumed.
"They're having fun. They argued for days when our radar picked up an
empty second stage in orbit. They're still ready to dispute for hours
about a supposed retrograde satellite that was spotted last year, was
watched for four turns, and then disappeared. Beer?"

"Too early," said Terry. "Thanks just the same."

Davis said earnestly, at the other side of the room, "I'd feel a lot
better if that thing last night hadn't splashed where it did."

"The bolide," said a voice humorously, "is a free animal."

The discussion went on. Terry saw Deirdre talking to a middle-aged woman
with a splendid sun-tan and a placid expression on her face. Doug and
Tony sat watchfully on the side lines, listening. Doug had been offered,
and had accepted, a sandwich. He ate it methodically.

Terry had a sudden feeling of unreality. Less than half an hour before
he'd been in torment and, but for Deirdre, on his way to death. On the
_Esperance_ there'd been so much that was absorbing in the way of fish
behavior that he'd forgotten some people were interested in other
things. Here a dozen people squabbled over the behavior of a meteorite.
Nothing could be of less consequence to the outside world. But in the
outside world, people argued about baseball, or golf, or politics....

Doug excused himself and slipped outside. Terry joined him there a
little later. Doug was smoking a cigarette, looking at the sky and the
palms.

"Pretty heavy discussion," said Terry.

"It's over my head," said Doug. "I got lonesome. It made me think of my
girl. She likes to talk like this. That's why ..."

He stopped.

"Is there an aqualung outfit on the _Esperance_?" asked Terry.

"Sure! Two or three of them. Mr. Davis had an idea they'd be useful.
Used one of them last week to look at the _Esperance's_ bottom-planks.
Why?"

"I'd like to poke around the bottom of the lagoon a little," said Terry,
with unconscious grimness. "Would you help?"

"Sure!" said Doug.

They went back to the _Esperance_. Doug got out two aqualung outfits.
They checked the valves and tanks and connections. Doug brought out two
spring guns. In half an hour they were in the outboard, headed for what
Doug said was the deepest part of the lagoon.

Arrived there, Terry tested the water with his finger and then went
overside. Instead of a spring gun, he used one of the fish spears that
seemed to be standard equipment for fishing, here. Doug stayed in the
boat to watch.

Terry'd guessed that what he looked for would be in the deepest part of
the lagoon. He was right. Within half an hour he'd speared five fish of
types that had no business being within two thousand fathoms of the
surface. He ignored the lagoon's normal inhabitants. He picked on fish
of a dark-red color, which is predominant in the depths but not
elsewhere. When the fish had extremely small eyes or extremely large
ones, he hunted them determinedly, knowing they were deep-sea fish. He
caught five, which was a good haul, even considering his previous
suspicions.

Doug inspected the catch as the outboard went back to the yacht. Terry
replaced his spear under the gunwale.

"They're queer fish," observed Doug. "I wouldn't want to eat them."

"Neither would I," agreed Terry. "But I feel a certain sympathy for
them. I think we've shared an experience."

He did. Fish so far from their normal environment would not have
migrated unless they'd been forced to. So these fish must have been
driven up from the blissful utter blackness of the abyss, which was
their habitat. He had a vivid memory of the kind of urging they'd
received, because of his recent swim outside the reef opening. That was
the experience he believed they shared.

He got his catch onto the _Esperance's_ deck and found some sharp knives
in the galley, while Doug put the aqualungs away. When Doug came
abovedecks again, he looked distastefully at the work Terry had
undertaken.

"Do you like to do that sort of thing?" he asked.

"Hardly!" said Terry. "But I want to get it done."

Doug watched for a moment or two.

"I'm pretty keen about poetry. Sometimes I feel I've got to sweat over
a poem that I need to get written. It's hard work. There's no real sense
to it. But I feel it's got to be done. I guess that's the way you feel
now."

"Perhaps," said Terry.

It wouldn't have occurred to him to liken the writing of verses to the
dissection of dead deep-sea fish, but Doug had a point. He went away
presently, and Terry completed the highly unpleasant task. He had just
finished flushing the deck clean when Deirdre came back from the
tracking station. He was already at work on the recorder when she
stepped onto the deck.

"You didn't stay," said Deirdre. "I was waiting for a chance to tell my
father about the hum outside the lagoon, but he was as deep in the
meteor argument as any of them. I still haven't told him."

"There's something else to tell him now," Terry remarked. "I went down
with an aqualung. Doug was standing by," he added at her gesture of
protest, "and speared some fish that don't belong here. I've dissected
them. Their swim bladders had been very skillfully punctured, so if they
went or were driven into lesser pressure, they'd leak instead of
bursting. That's how they survived coming up from the depths. But the
main thing is this."

He held out a small plastic object in his hand. It was about an inch in
diameter and two in length, and there were inclusions in the clear
material. There were plates and threads of metal. They had that look of
mysterious purpose that highly-developed technical devices have.

"This was fastened to the fin of a fish that belongs as far down as a
fish can go," he said. "I've found out one of its purposes. When it is
in the water, it makes a sound more acute than a whistle every time
another sound strikes it. Try that on your piano!"

Deirdre stared.

"I'm saying," he repeated, "that it takes in one sound and gives out
another. It's ... it could be a relay. What is that for? What's it all
about? What does it mean? And I ask just those questions because I don't
dare ask who and why!"

"What ... what will you do?" asked Deirdre absurdly.

"I've no idea," Terry told her. "I've got a feeling that the wise thing
to do would be to settle down somewhere and buy a shop, and forget all
this. If I don't think about it, maybe it'll go away."

"I'll get my father and see what he says."

"Tell him," commanded Terry, "that I want to try out my fish-driving
horn. I'd like to have witnesses. If this foolishness has to be reported
to somebody, we need evidence of the facts. I want to drive fish and see
how many deep-sea ones there are in this lagoon, and how many of them
have spy-devices on them."

Deirdre turned away. Then she turned back.

"Spy-dev--"

"I slipped," said Terry. "I shouldn't have said that. Forget it. Just
tell your father I have an extremely urgent impulse to drive fish, and
would he come and help."

Deirdre looked at him strangely, and went onto the wharf to search for
her father.

Terry paced back and forth on the _Esperance's_ deck. In a few minutes
Davis and the crew-cuts appeared with Deirdre. But they were not alone.
Straggling behind them came nearly all the personnel of the tracking
station. There would be somebody on official duty, of course. But here
was the bespectacled Dr. Morton; the bald young man who'd offered Terry
beer; and the installation cook; a typist, and specialists in radar and
other abstruse subjects.

Deirdre said, "I told them about the fish-driving business and they want
to see. They stopped arguing about last night's bolide to take ringside
seats. All right?"

Terry shrugged. He had the recorder already set up. He'd taken a section
of the tape made where the sea was bright, at the place where the
loudest of the unpleasant humming noise was recorded. He'd made a loop
of it so it would play over and over.

He played the much-amplified sound through the underwater horn held in
the air. The result was a raucous bellowing noise. He lowered it into
the water. The horn touched the surface and went under.

Instantly, the fish of the lagoon seemed to go crazy. All the surface
broke and writhed and splashed. There was an incredible number of fish.
Terry turned the horn on one side. In this way, not all the water was
filled with the intolerable noise, but only a net-like beam of it raced
across the water. Within that line the fish continued to leap
frenziedly. The rest of the lagoon suddenly quieted down. In a little
while the beam's space, also, grew quiet. But that was because the fish
that had been previously caught in it had escaped.

"I'm afraid," said Terry, "that this isn't going to be very
entertaining. I'm going to sweep the beam across the lagoon, pushing the
fish ahead of it, until I should have them all in one small area."

It was curious that he felt uncomfortable as he set about his task. But
he'd experienced the sensation this sound produced. And it was not very
pleasant.

He turned the beam around, slightly. Again, there were sudden
splashings. They died away. He turned the beam again. It was a nasty,
snarling vibration in the water. So far as fish were concerned, it was
more like a wall than a net, because not even the tiniest living
creature could penetrate it. Not only fish fled before it. Shrimps and
crabs and all types of crustaceans jerked and crawled and swam ahead of
its motion. Jellyfish writhed when it touched them. Sea cucumbers
contorted themselves. Everything that lived in the lagoon and could swim
or crawl or writhe moved before the invisible barrier. Presently, the
effect of crowding could be seen, and fish began to leap out of water.

"This is a great advance in civilization," said Dr. Morton. "Men
invented guns and destroyed the buffalo and the passenger pigeon! You
may have made it possible to depopulate the sea!"

Terry did not answer. The morning sun shone brightly, a gentle breeze
made ripplings on the lagoon, the palms waved their fronds in languid
gestures, and the surf could be heard booming and splashing on the outer
reef. And about two dozen people stood on the wharf or on the
_Esperance's_ deck and watched a spliced section of recorder-tape go
through and through a recorder, which was set to make a sound underwater
that could not be heard by the people above.

The fish of the lagoon had crowded themselves into a minor embayment of
the shore. There were innumerable leapings there.

"There should be plenty of fish collected now," said Terry
distastefully. "I certainly can't herd them ashore."

The outboard boat pushed away from the yacht, its motor roaring. It
reached the area in which the water seemed to seethe and surge with the
motion of densely-crowded swimming creatures. The people in the boat
examined the surrounding water, then the boat came back at top speed.

"They're there!" called Davis. "And thick enough to walk on! I clearly
saw some freaks that must come up from the bottom! We want to collect
them!"

"I speared five just now," Terry told him, "and one of them was wearing
this."

He held up the plastic object he'd found. There was silence for a
moment. Then Dr. Morton said briskly, "We'll want fish spears. We'll
take all the boats and go after some more of these piscatory oddities.
Who's best with a spear?"

Davis would go. He could use the two fish spears that were standard
equipment for the outboard. The staff of the tracking station scattered
to launch other boats. Only Terry and Deirdre remained on the
_Esperance_. It was necessary for someone to stand by the recorder.

Boats moved away across the water. One stout member of the island's
staff trudged along the shore.

"You're driving them," said Deirdre. "You are right."

"I wish I weren't," said Terry.

"Why?"

"You know how these weird fish got here," he said impatiently. "They
were driven here. You know how they've been kept here. I experienced
that! I told you why they didn't die when they came up from thousands of
fathoms! Now, what's the only possible purpose for their being here? Put
it more scientifically! What is the consequence of these happenings, so
that to some biological entity it would be a favorable happening?" His
tone was sardonic, at the end.

"I don't know."

"I hope I don't either," said Terry dourly.

He was in no amiable mood. He'd made too many guesses like those Davis
had mentioned. He was beginning to have less and less hope that they
were untrue. Each new development made any imaginable cause of these
events just so much more appalling to think about.

In an hour, three boats came back from the small bay into which all the
fish of the lagoon had been crowded. Terry turned off the underwater
horn. A stout man walked slowly along the shore with a heavy burden of
known edible fish. He was the island's cook, and he had speared them
from the beach. The boats, altogether, had speared and captured not less
than sixty specimens of fish normally found only many thousand feet
below the ocean's surface. Upon inspection, all of them were found to
have deftly punctured swim bladders, punctured with so slender a barb
that the opening would close by itself, except when serving for the
release of intolerably expanding gas.

Before noon, seven more plastic objects had been found among the
deep-sea fish. Three seemed identical to the one Terry had found. Two
others were identical to each other but of a different kind, and the
last two were of two different types altogether. Only those like the one
tested by Terry seemed sensitive to sounds, which they changed into
other sounds at a twenty-thousand-cycle frequency, or higher. The rest
did nothing that could be detected.

During the afternoon, news came to distract the absorption of the
tracking station staff in the lagoon's fish. The short-wave operator
came running to the wharf, waving a written message. The deck of the
_Esperance_ was not a pretty sight, just then, with the dissection that
had been taking place on it. Jug was beginning to flush the debris
overside.

The short-wave operator arrived. Dr. Morton read the message. He raised
his voice.

"Here's a fancy one!" he told the assembled company. "Space-radar's
picked up a new object coming in from nowhere. It will probably orbit
once before it hits the air and burns. By the line of motion it should
pass nearly overhead here. We're alerted to get it under observation
and watch it!" He waved the message in a large gesture. "We've got to
get ourselves set up! The argument on the path of last night's bolide
and why it fell where it did is again in order. We'll see what we can do
about computing the fall-point of this!"

He headed for the shore. The staff followed, babbling. Somebody's
mathematics would be verified, and with it his views on the possible
effects of terrestrial magnetism on objects approaching the earth.

"We ought to get these plastic things to Manila," Davis said slowly.
"They need to be compared to others. But I think we'll wait and see this
bolide first."

A heated argument started in the tracking station staff. From Dr. Morton
downward, almost to the station's cook, the most varied predictions were
made. The official computation from Washington, made from the observed
course and height and speed, predicted that the bolide would land
somewhere in the South Pacific. Dr. Morton predicted a fall in the China
Sea, within a certain precisely stated number of miles from Thrawn
Island. Other predictions varied.

At exactly fourteen minutes after eight--a time way ahead of the
official schedule but exactly as Dr. Morton had predicted--the bolide
passed overhead. It was an amazing spectacle. It left a trail of flame
behind, across thirty degrees of sky. It went on and on....

Less than ten minutes later the short-wave radio informed the island
that the shooting star had been seen to fall in the sea. It had been
observed by a plane which was then circling over the area in which the
_Esperance_ had encountered the circle of shining sea. The plane was
there to see if the phenomenon would occur again. It didn't.

But the plane saw the bolide as it struck the sea, and huge masses of
steam and spray arose. The bolide was not white-hot, then, as when it
passed over Thrawn Island. It was barely of dull-red brightness. It hit
the sea and sank, leaving steam behind.

The water was forty-five hundred fathoms deep at that point.




_Six_


Fourteen hours later the _Esperance_ made ready to sail from Thrawn
Island. Her purpose was to carry the plastic objects to Manila, where
they would be turned over to specialized laboratories to be studied.
Five such objects had been found before: one in the Thrawn Island
lagoon, while the satellite-tracking station was under construction, and
four attached to exotic fish brought to market by the commercial fishing
boat _La Rubia_. Now there were eight more, of four different kinds. To
the laboratories would go Terry's observation that one kind of these
objects absorbed sound at audible frequencies and retransmitted it at
much higher ones, but only under water. All this was very interesting
and very puzzling.

But a serious disturbance had arisen at the tracking station.

Dr. Morton came to the _Esperance_ before her departure. He had a
problem. He'd predicted to the minute, and almost to the mile, the
landing of the bolide of the night before. That was the first accurate
prediction of the kind in history. But his forecast stood alone in its
precision. Nobody else had even come near being right. Now he was being
insistently queried by astronomers the world over. They wanted to know
how he'd done it. In particular, they wanted to know how he'd figured
that the bolide would lose just so many feet per second velocity,
neither more nor less, in a three-quarter orbit around the world. Nobody
else had such a figure in his equation for the landing spot. Dr. Morton
had. His prediction had been exact. Where did he get that necessary but
inexplicable figure?

He beckoned Davis and Terry to go below with him, in the _Esperance's_
after cabin. Terry hesitated.

"You may as well hear my troubles," said Morton vexedly. "You're largely
responsible for them."

Terry followed uneasily. He didn't see how Dr. Morton could hold them
responsible. He had guarded his own guesses about the _Esperance's_
discoveries against even the slightest expression. He couldn't let
himself believe in their correctness, but he was appalled at the
inadequacy of all other explanations of past events.

"In sixteen months," said Morton annoyedly, down below, "we've spotted
six bolides coming in to land in the Luzon Deep. That's out of all
reason! Of course, it could be a mathematical series of wildly unlikely
coincidences, such as probability says may happen sometimes. Up to last
night that seemed to be a possible explanation."

Davis nodded. His expression was odd.

"But now," said Morton somehow indignantly, "that's ruled out! It's
ruled out by last night's bolide, and yesterday's fishing experiment,
and that business of the shining sea, plus those damned plastic gadgets
and deep sea fish thriving in shallow water! There's no reasonable
explanation for such things, and they're not mere coincidences!"

"I'm afraid," admitted Davis, "that they're not."

"The obvious explanation," said Morton doggedly, "I refuse to name or
consider. But nevertheless the question is not whether a theory or an
explanation is unlikely or not. The question is whether it's true!"

Davis nodded. Terry had to agree. But the way people are trained in
modern times puts a great emphasis on reason, often at the expense of
fact. Terry felt the customary civilized reluctance to accept a
statistically improbable idea.

"I'm on a spot," fumed Morton. "I calculated that the damned bolide
would slow after it went into orbit around the earth. I calculated that
it would slow exactly so much. Do you want to know how I figured how
much it should slow down? I'll tell you! I calculated exactly how much
it would have to slow to be able to fall into the Luzon Deep! It did
slow. It did fall there. But how am I going to explain that to
Washington?"

Terry suddenly felt a warm sympathy for Morton. It is bad enough to
dispute with oneself when something incredible happens. But Dr. Morton
had gone out on a limb. He'd been caught psychologically naked telling
the truth, and now he was asked to explain it. And he couldn't.

"This thing has got to come to a head!" he said angrily. "Sooner or
later they'll find out that I don't calculate where it'll land by its
behavior in space but by its landing spot! Davis, you've talked about
stirring something up. For Heaven's sake, do it! You may save my
reputation! And you...."

"I'll try to think of something," said Davis reservedly.

"I've got to have proof that my suspicions are right or wrong before I'm
ruined. I know what you're planning to do. Do it! Is there anything that
can be done here to help?"

Davis spread out his hands helplessly. But Terry said, "Yes. Send a boat
every so often to listen at the gap in the reef. Put an oar overboard
and put your ear to the handle. You should hear the underwater hum, if
it's still there. It was there this morning."

Morton looked at him suspiciously.

"Why check on it? Should it change?"

"Perhaps," said Terry. "We've speared most of the deep-sea fish in the
lagoon. Maybe we've interfered with ... the reports from the plastic
objects, telling what was happening up here. There may be a reaction. If
so, most likely the humming will stop, and after a longer or shorter
time begin again. And then, if my guess is right, there'll be more
deep-sea creatures in the lagoon."

"Ha," said Morton. "I think you and I have the same kind of delusions!
All right. I'll see that that's done. You two do the rest."

He went abovedecks. When Terry got on deck, Dr. Morton's angular figure
was already marching along the wharf to the shore.

There was no ceremony of departure. The _Esperance_ cast off and her
engine started. She moved toward the lagoon entrance under power only,
but her sails were hoisted as she floated on, and Jug Bell was trimming
the jib when she cleared the opening to the sea.

The humming in the water was still audible to the submarine ear, close
to the land. It occurred to Terry to take a bearing on the source of the
sound, noting both the compass direction and the vertical angle from
the reef. If his vertical-angle reading was accurate, a line from the
reef to the source of the sound would touch the bottom at twenty-seven
thousand feet down, between four and five miles away.

The _Esperance_ sailed on. The humming duly faded away. Terry left the
recorder picking up undersea sounds, without recording them. It relayed
the underwater sounds to the people on deck. It was in Terry's mind to
keep at least half an ear cocked to it, in case the mooing sounds, heard
and recorded elsewhere, should come again.

They did not. The _Esperance_ went methodically on her way, headed south
by east, under sail. A slowly swaying horizon of unbroken sea was all
about. There was nothing in the least unusual or mysterious to be seen
anywhere.

Presently, Terry found himself in conversation with Deirdre, and the
world seemed so blatantly normal that their talk dodged all unusual
trends. They talked about their childhoods, about things they had done
and places they had seen.

At about four in the afternoon Nick bellowed, "_Thar she blows!_" in a
fine attempt at proper whaling ship style, and all the _Esperance's_
company joined to watch a spouting far ahead. The yacht changed course a
little, and presently reached a pod of sperm whales at the surface. The
huge dark bodies moved leisurely through the water. Jud displayed great
erudition on the subject and explained in detail how their spouting
proved them to be sperm whales. Deirdre pointed out a baby whale close
beside a larger one.

They sailed on, leaving the whales behind. The crew-cuts, inevitably,
argued about them. They canvassed all the information and misinformation
they possessed and came up with a heated discussion about whales, how
they can swim down to the enormous depths without suffering from the
bends on rising again. Then the conversation turned to the food they
eat. Whalers, in the old days, had found snouts of squids and undigested
sections of squids' tentacles in the stomachs of harpooned sperm whales.
There were reports of sections of tentacles four feet thick, implying a
startling total size, all of which proved that the whales had been at
the bottom of the ocean, where such gigantic squids can be found. These
were the reports of reliable whaling skippers. Certainly the scars made
by the tentacular arms of huge squids, indicating battle, have been
found on the skin of sperm whales, and there have been reports of
battles on the surface between whales and squids of sizes most
naturalists would be unwilling to certify. In such cases it was assumed
that the squids had been attacked at the bottom of the sea and had
followed the whale to the surface when it came up in need of air.
Certainly only an enormous squid would be able to sustain a battle with
a whale.

Terry listened to the discussion. Everybody had his own opinion.

"You'd never settle the argument, unless you could put a camera and a
flash gun on a whale and get an instrument-report from it."

Which was not a new idea, of course. But it was curious that the thought
of sending self-reporting instruments down to the bottom of the sea had
been suggested by his own suspicion that similar instruments had been
sent up from below. Sounding lines had been lowered with thermometers
and nets and sampling machines. Core-takers had been dropped to get
samplings of abyssal mud. But tethered instrumentation is never more
than so useful.

Deirdre said something. Terry realized that she'd repeated it. He'd
become absorbed in the possibilities of instrument-reporting from the
surface to the depths and back again.

"You're not listening," protested Deirdre. "I'm talking about the
bathyscaphe that ought to be in Manila any day now."

"I'm trying to picture myself going down in a bathyscaphe," said Terry
hastily. "I don't think I'd like it."

A bathyscaphe is a metal sphere with walls and windows of enormous
thickness, hung from a metal balloon filled with gasoline for flotation.
It is lowered to appalling depths with the help of heavy ballast, and is
equipped with electric motors for independent motion. It carries
powerful electric reflectors which allow as much as thirty or forty feet
of visibility. It rises to the surface again when its ballast is
dumped. There are only three such undersea exploring devices in the
whole world.

"I'm not at all sure you wouldn't like it," said Deirdre.

Terry scowled at his own thoughts. There are opinions a man holds firmly
without ever being aware of them, unless they are challenged, and if
that happens, he is deeply suspicious of the challenge because it
suggests that his opinion needs to be re-examined. Terry had been
gathering scraps of information here, and unquestionable items there,
resisting a conclusion all the while.

It seemed fantastic to think that the plastic objects carried by
deep-sea fish out of their natural environment were actually man-made
instruments--telemetering apparatus closely comparable to the devices
used to transmit information from outer space. It was wildly imaginative
to suppose that they transmitted information from the water surface to
the depths of the ocean; that fish had been driven up from the abyss in
order to report what went on at the surface. Report to whom? It was the
most fantastic of fantasies to think that there was curiosity, in the
Luzon Deep, about the manners and customs of the inhabitants of the
surface waters and of those areas not covered by the sea.

But Terry stopped short. There were limits to the ideas he would allow
his brain to think about.

Deirdre walked away, and he assured himself he never thought of anything
so ridiculous as the conclusions he had just reached. Presently, dinner
was served, and Terry painstakingly acted like a perfectly rational
person. After dinner Davis, as usual, settled himself down to enjoy a
program of symphonic music from San Francisco, many thousands of miles
away. And Deirdre vanished from sight again.

Later on Terry found himself alone on the _Esperance's_ deck, except for
Nick at the wheel--a mere dark figure seen only by the light of the
binnacle lamp. There was a diffused, faint glow coming from the
after-cabin hatch. Up forward, one of the crew-cuts plucked a guitar,
and Terry could imagine Doug dourly trying to read poetry despite the
noise. The sails were black against the sky. The deck was darker than
the sea.

Terry's guesses haunted him. He assured himself that he did not
entertain them even for an instant. They were absurd! A part of his mind
argued speciously that if they were absurd there was no reason not to
test them. If he was afraid to try, it would imply that at least part of
him believed them.

He picked up one of the plastic objects, and moved the recorder close to
the lee rail. It still transmitted faithfully, at minimum volume, the
washing of the waves as heard from beneath, and occasional small sounds
from living creatures, generally far away in the sea. Heeled over as the
_Esperance_ was, his hand could reach down into the rushing waters
overside.

He came to a resolution. He felt foolish, but by now he was determined
to try an experiment. Tiny light-blue sparks flashed where the water
raced past the yacht's planking. When he dipped his hand, water piled up
against his wrist and a streak of brightness trailed away behind.

He tapped the plastic object against the hull. One tap, two taps, three
taps, four taps. Then five, six, seven, eight. He went back to one. One
tap, two, and three and four. Five and six and seven and eight.

The recorder gave out the tappings the underwater microphone had picked
up. It seemed to Terry that the loudspeaker struggled to emit the
shrillest imaginable sounds in strict synchrony with the tappings.

Then Deirdre's voice came quietly, very near.

"I don't think," she said evenly, "that that's a fair thing to do."

He'd been bent over the rail in an awkward position. He straightened up,
guiltily.

"I know it's nonsense, but I was ... ashamed to admit ..."

"To admit," Deirdre concluded for him, "that by tapping numbers with a
plastic spy-device, you hoped to say to whom it might concern that we've
found a communicator, and we know what it is, and we're trying to get in
touch with the intelligent creatures who made it."

To hear his own self-denied guesses spoken aloud was appalling. Terry
instantly disbelieved them entirely.

"It's ridiculous, of course," he protested. "It's childish...."

"But it could be true," said Deirdre. "And, if true, it could be
dangerous. Suppose whatever put those plastic gadgets on the fish
doesn't want to be communicated with? Suppose it feels that it should
defend the secret of its existence by killing those who suspect it? I
wasn't spying on you," she added. "I heard the tappings down below."

Then she was gone. He saw the interruption in the light from the
after-cabin hatch as she went below.

He was suddenly filled with horror at the idea that if his guesses did
prove to be right, he might have endangered Deirdre. And then he ceased
to feel foolish. He felt like a criminal instead.

For a long, long time he listened with desperate intensity to the
recorder, lest he hear some reply to his signals.

But no answer came. The sounds from undersea remained utterly
commonplace.

When morning arrived he was in a state of desperate gloom. At breakfast
Deirdre acted as if she considered the incident closed. And, such being
the nature of men, Terry felt worse than before.

He was not wholly at ease again, even when that afternoon the
_Esperance_ sailed in past Cavite and Corregidor and into Manila Bay. A
new ship was at anchor in the harbor. It was a stubby, stocky ship which
Davis regarded with interest.

"That's the _Pelorus_," he told Terry as the yacht passed within a mile,
on the way to her former anchorage. "She's the hydrographic ship with
the bathyscaphe on board. We'll visit her. I'll get Nick to call her on
short-wave."

He went forward, where Nick was making ready to drop the anchor. Davis
took over the chore, and Nick went below.

"Are you going ashore?" asked Deirdre.

Terry shrugged. "I've no reason to."

She looked relieved. "Then you'll stay with the _Esperance_
until--things are settled one way or another? I mean, you're really
enlisted?"

"Until there are no more ways left for me to blunder," said Terry
distastefully. "I'm about through the list, though."

"Not at all!" protested Deirdre. "Tapping numbers was really a very good
idea. I was horrible! I scolded because you'd kept it a secret from me.
I'd have been proud if I'd thought of it first!"

Nick came back and spoke to Davis. Davis came aft.

"The _Pelorus_ will send a boat as soon as we've anchored," he told
them. "They've heard something and want to see the plastic objects."

"I'd like the long end of a bet that they don't believe in them, or us,"
Terry said abruptly. "They're established authorities on the ocean
bottom. They know a lot. They probably know so much they can't really
believe there's anything more to know than what they're busy finding out
now."

Davis shook his head. He was confident. The _Esperance_ anchored, almost
exactly where she'd been when Terry first came on board. Within half an
hour a boat arrived from the _Pelorus_. Terry repeated his refusal to go
along. Deirdre went along with her father.

They came back a little over an hour later. At first Davis was almost
speechless with fury. Then he told Terry, choking on his rage,
"According to them, the plastic objects are a hoax. The hum is a school
of fish. We aren't trained observers. At Thrawn Island they're
astronomers and they simply don't know anything about biology. And we
should realize that it's starkly impossible for intelligence to develop
where the oxygen supply is limited. It's unthinkable that abyssal fish
should have their swim bladders punctured so they won't explode from
release of pressure when they come to the surface. Those in the lagoon
aren't abyssal fish, just unfamiliar species!"

"Well?" Terry asked.

"Oh, they're going to make a bathyscaphe dive!" said Davis as angrily as
before. "As a matter of courtesy to somebody--not us. They'll make it
where we found fish packed in a circle. That happens to be the deepest
part of the Luzon Deep, in any case. They don't object to our sending
our dredge down first. They will be politely interested if it comes back
up."

"I," announced Deirdre, "I am so mad I could spit!"

"There's no use in our staying here," said Davis, seething. "Our dredge
should be ready. We'll go up to Barca and tow it to the point we want to
send it down."

He ordered Nick to get ready to lift anchor.

"One question," Terry said finally. "Did you mention the bolides?"

"No!" snapped Davis. "Would I want them to think I was crazy?"

He stamped away.

The _Esperance_ put to sea again. She sailed north along the coast. At
dinner everybody was quiet. It was the only meal, since Terry's joining,
that had not been enlivened by an elaborate argument on some subject or
other. Davis was still in an abominable mood. He knew it, and held
himself to silence.

Later, Terry and Deirdre talked together. They refrained tacitly from
speaking of marine biology or any reasons for tapping plastic objects
against the _Esperance's_ hull. They discussed only trivia, but somehow
Terry found any subject absorbing, when he was with Deirdre.

After a while she went below, and he stayed abovedecks, smoking. The
moon had not yet risen when he turned in.

They sailed into the small harbor of Barca at ten in the morning. By
twelve, local boatmen had towed out an ungainly object some thirty-two
feet long. They tethered it to bitts at the _Esperance's_ stern. By one
o'clock they had loaded on her deck a large, folded sack of sailcloth
and half a dozen specially-cast concrete blocks with eyed iron rods
cemented in them. At half-past one Deirdre, who had gone ashore in one
of the yacht's own boats, came back with innumerable supplies she'd
bought. At two o'clock the _Esperance_ went out to sea again.

The towed object was a construction around a central wooden spar with an
iron tube at its top end and half a dozen lesser spars linked loosely to
its bottom. A mass of fishnet was fastened to the smaller spars and
heavy ropes were holding the spars and the net in place during its tow.
There was a hook for attaching the main spar to the concrete sinkers.

"It opens like an umbrella," explained Deirdre. "We'll hoist it upright
barely out of the water, and fasten on the weights. The canvas bag fits
on that iron pipe. When you let it go, it sinks like an umbrella that's
tightly closed, but when it touches bottom the weights spread it out and
an explosive charge automatically goes off in that iron tube. It's
special explosive. The gas it makes inflates the canvas bag, which can't
burn underwater, and that floats the whole thing back up with the ribs
of the umbrella stretched out and spreading the net between them. It
should catch anything it encounters as it rises. As the pressure lowers,
the excess gas can escape through a relief-valve. This dredge is
experimental. If it works, it can be modified to do lots of things."

"Such as poking at things we don't believe in," said Terry drily. "That
explosion ought to stir up anything in its neighborhood. It'll be much
more disturbing and audible than a few light taps against the
_Esperance's_ hull!"

Deirdre grinned ruefully and did not answer.

The bulky tow slowed the yacht. She did not reach the position of the
fish-filled circle until after nightfall, and it was necessary to have
plenty of light by which to locate the inflated bag when it came to the
surface, so nothing could be tried until the following morning. A short
while before daybreak, lights appeared at the horizon. Red and green
sidelights, and white central lights. It was a steamer. It came closer
and closer. Presently, it turned and headed upwind and went dead slow,
barely keeping steerage. It was the _Pelorus_.

Dawn arrived in a golden radiance which thrust aside the night. The
_Pelorus_ shone brightly in the first rays of the sun. A large object
was hoisted out of her hold. Its shape was that of a gravid goldfish,
with a smaller sphere hanging beneath it. It went overside, slowly, and
there it floated, rolling wildly on the waves. For a very long time
nothing seemed to happen. Then the water-level of the float sank a
little. It was being filled with gasoline, which is lighter than water
and practically incompressible.

On the _Esperance_, the tow had been pulled alongside and the yacht's
powerful winch hauled it upright. The yacht heeled over from the weight.
The crew-cuts fastened the canvas sack in place, and Davis loaded the
explosive charge into the iron tube. The crew-cuts cleared the nets.
This preliminary operation seemed promising, and it was quite likely
that the dredge would operate as it was designed to do.

The _Pelorus_ whistled impatiently. Nick abandoned his job and went
below to the short-wave set. He returned shortly after.

"The _Pelorus_ says she'll be ready to send the bathyscaphe down for a
test dive in two hours," he reported. "She says she will object if our
gadget is floating free at the time, on the chance that it might
interfere with the bathyscaphe. She asks if you can send our dredge down
right away and get it over with."

"Tell them yes," said Davis. "In five minutes."

He compressed his lips. The _Esperance's_ device, though clumsy, was
fundamentally simple. Five minutes later the top of the central spar was
level with the water. "Cut away," said Davis.

Doug slashed the single rope holding the dredge. It sank immediately.

The recorder gave off the sound of waves. Occasionally, very
occasionally, a chirping or a grunt could be heard. Twenty minutes.
Thirty.

There was a "crump!" from the loudspeaker which reported underwater
events. The sound seemed to come from very far below. Even a small
amount of explosive makes a very considerable concussion when it goes
off so far down, and the shock travels in all directions instead of
merely upward. The recorder picked up that concussion as a deep-bass
sound.

The sun shone. The wind increased. Waves marched in serried ranks from
here to there.

A long, long time later the inflated canvas bag came up and was floating
on top of the waves. The _Pelorus_ whistled. Nick went below. A few
minutes later he came up again to report.

"The _Pelorus_ says not to cast our dredge adrift. They're sending the
bathyscaphe down unmanned, to test all apparatus before a manned dive.
They don't want any debris in the sea."

"Tell them we send them a kiss," snapped Davis, "and they needn't
worry!"

The _Esperance_ approached the floating bag. Jug swung out on the
lifting boom and hooked it. The winch hauled it out of the water. The
concrete weights were gone. What the nets had captured was not pretty to
see. A dead fish with foliated appendages had come up from far below, to
judge by what its unpunctured swim bladder had done to it in
uncontrolled expansion. Davis said curtly it was _Linophrine arborifer_,
belonging two thousand fathoms below. An angry-looking creature,
similarly dead, was _Opisthoproctus grimaldi_. It belonged deeper than
the other. There were other specimens. A _genostoma_ of a species the
books didn't picture; a _Myctophum_; and various other creatures, mostly
as grotesque as their scientific names. All were abyssal fish. They had
died while rising from a pressure of several tons per square inch to
surface-pressure only.

"It worked," said Davis curtly. "I almost wish it hadn't. Let it down
into the water again. We'll jettison it when the _Pelorus_ gives us
permission."

Time passed. More time. Still more. The bathyscaphe was now in the
water, practically awash. Only a small conning tower showed above the
waves. Men swarmed around it.

There came a query from the _Pelorus_. The _Esperance_ gave assurance
that the deep-sea dredge had returned to the surface and would be kept
there.

The bathyscaphe was allowed to sink.

The recorder on the yacht began to pick up deep-toned mooing sounds from
the depths.

Presently, the mooing sounds ceased.

Two hours later, waves broke over an object completely awash on the
ocean. The _Pelorus_ steamed cautiously toward it. Boats went down from
her sides and surrounded the float.

After a long time the _Pelorus_ got alongside and men quickly fastened
the huge buoy to the ship. Then the down-wind sea changed its
appearance. A reek of gasoline reached the _Esperance_.

"Something happened," said Davis dourly. "They're dumping the
gasoline--not even pumping it aboard. Let's get out of the stink."

The _Esperance_ beat to windward. The _Pelorus_ began to lift something
large and ungainly out of the water. The _Esperance_ went down-wind to
take a look at it.

The yacht went past no more than fifty yards away, just as the
bathyscaphe left the water and swung clear.

The bathyscaphe's conning-tower was gone. It had been torn away by brute
force. The three-inch-thick steel globe.... Half of it was gone. The
rest was crushed. The sphere, which had been designed to resist a
crushing pressure of ten tons per square inch, had been ripped in half!
It had been bitten through. Bitten!

There was no comment by anybody on the _Esperance_.

Half a mile from the oceanographic ship, Davis said in a peculiarly flat
voice, "Cut away the dredge. We won't try to use it again."

Someone slashed the inflated canvas bag. It collapsed. Somebody cut away
a rope. The free dredge sank, slowly. It would never come up again.

The _Esperance_ changed course. She headed north by west. There was
still no conversation at all. The yacht seemed to tiptoe away from the
scene of the bathyscaphe's destruction.

A long time later, Deirdre said tentatively, "Have you been making
guesses, Terry?"

"Guesses, yes," he admitted.

"Such as?"

"Your father denied that the dredge was designed to stir up whatever
gathered the fish together and then carried them down to the bottom of
the sea. I was right there with him in the denial, but that's what we
intended, just the same. We said we didn't believe there was anything
there, so it couldn't do any harm to poke it. We poked, all right! Our
dredge, and then the bathyscaphe...."

"But what ..."

"And a bolide fell right there a couple of nights ago," said Terry
irrelevantly. "I wonder what the entity on the ocean-bottom thought of
the bolide. Hm." He paused. "I wonder, too, what the bolide thought of
what it found down there. Is that too crazy for a sane man to think,
Deirdre?"

She shook her head.

"Why is my father working on this business?" she asked. "And why are the
boys helping, and why do radar stations tell us what they find out, and
why did the Philippine Government ask the _Pelorus_ to make a
bathyscaphe dive at just that spot?"

Terry blinked at her.

"Too crazy for official notice, eh?" he said, "but too dangerous not to
check up on! Is it absolutely certain that the bolides are bolides?"

"No."

"Thanks," said Terry. He pursed his lips as if to whistle. "I've been
thinking of this thing as a puzzle. But it isn't. I'm very much afraid
it's a threat!" He paused. "Y-y-es. I've just made a new guess. It adds
everything together. I do hope it's wrong, Deirdre! I've got cold chills
running up and down my spine!"




_Seven_


As the _Esperance_ sailed northward, she looked almost unreal. From a
distance she might have been an artist's picture of an imaginary yacht
heeled over in the wind, sailing splendidly over a non-existent ocean.
The sky was a speckless blue, the sun was high.

But she was real enough, and the China Sea around her was genuine, and
what had taken place where the _Pelorus_ lay now hull-down, stowing a
ruined bathyscaphe in her hold, had unquestionably taken place.

Something monstrous and terrible was hidden in the dark abyss below the
yacht. The ferocity of its attack on the bathyscaphe was daunting. And
ferocity has always, somehow, a suggestion of madness about it. But the
humming sound in the sea was not the product of madness. It was a
technical achievement. And plastic objects with metal inclusions....

Davis joined Deirdre and Terry. Before Davis could speak she said, "I
can't imagine any guess that will add everything together, Terry."

Davis made a jerky gesture.

"Today's business is beyond all reason," he said unhappily, "and if
there ever was an understatement, that's it! If there can be any
conceivable motive for the plastic objects, which the _Pelorus dismisses
as hoaxes, the motive is to use them to find out_ something about
surface conditions; that is, for surface conditions to be reported back.
And that's not easy to imagine. But try to think of something easier!
And yet, such mindless ferocity as attacked the bathyscaphe ... that
wouldn't be curious about the surface!"

"No-o-o-o," agreed Terry. "It wouldn't. But we'd set off a bomb down
below to stir things up. A couple of hours later the bathyscaphe went
down. A stupid and merely ferocious thing of the depths wouldn't
associate a bomb that exploded with a bathyscaphe that came down two
hours later. It took intelligence to make the association of two falling
objects with danger."

Deirdre beamed suddenly.

"Of course! That's it! Go on!"

"Curiosity implies intelligence," said Terry carefully, "and
intelligence is a substitute for teeth or claws. We don't assume that
the fish that carry the plastic gadgets made them. Why assume that
whatever attacked the bathyscaphe did it of its own accord? We believe
that something else makes the deep-sea fish come up into the Thrawn
Island lagoon, don't we? Or do we?"

"We pretend we don't," said Deirdre.

Davis nodded reluctantly.

"Yes, we pretend we don't," he agreed. "But if intelligence is involved,
I find myself getting frightened! We humans are always terrified of
strange types of intelligence, anyhow. If it's intelligence that isn't
human ..."

Nick came up from below.

"Thrawn Island calling," he reported. "They say the hum at the lagoon
opening stopped for some forty-odd hours and then started again. They
ask if we're coming. I said we were on the way. They're standing by.
Anything we should tell them?"

"We'll get there some time after sunset," said Davis. "And maybe you
should tell them about the _Pelorus_ and the bathyscaphe."

Nick grinned briefly. "I did. And the guy on Thrawn Island said 'Hooray'
and then explained that he said that because he couldn't think of
anything that fitted the idea of something biting holes in three-inch
steel." He added, "I can't think of a proper comment, either."

"We'll get to Thrawn Island after sunset," repeated Davis. "Then we'll
see what we find in the lagoon--if anything."

Nick started back toward the bow. He stopped.

"Oh, yes! It wasn't a scientific guy talking, just the short-wave
operator. The science staff is all busy. He said they heard an hour ago
that another possible bolide's been spotted by a space-radar back in the
US. It was picked up farther out than one's ever been spotted before.
Five thousand miles high."

Davis nodded without comment. Nick went forward and disappeared below.

A school of porpoises appeared astern. They caught up with the
_Esperance_. They went rocketing past, leaping exuberantly for no reason
whatever. They cut across the yacht's bow and zestfully played around
her two or three times, then went on, toward a faraway horizon. They
managed somehow to give the impression of creatures who have done
something they consider important.

"It's said," said Terry, "that porpoises have brains as good as men's. I
wish I could get one or two to talk! They might answer everything! I'm
getting obsessed by this infernal business!"

"I've been at it for months," said Davis. "In the past week, though,
with you on board, I have found out more things I don't understand than
I believed existed!"

He walked away. Deirdre smiled at Terry.

"My father paid you a tribute," she said. "I think we've been wasting
time, you and I. We do a lot of talking to each other, but we haven't
been applying our massive brains to matters of real importance."

"Such as what?" asked Terry dourly.

"Foam," said Deirdre. "Big masses of foam seen to be floating on the
sea. Always over the Luzon Deep. Photographed by a plane less than a
month ago. Reported by fishermen much more often than you'd suspect. At
least once a ship sailed into a foam-patch and dropped out of sight,
exactly as if there were a hole in the sea there. Let's talk about
that."

They settled down on the after-cabin roof and began a discussion on the
foam-patches, for which there was no hint of an explanation. Then
Deirdre mentioned that when she was a little girl she'd always been
fascinated by the sight of her father shaving. The foam--the
lather--entranced her. And somehow that led to something else, and that
to something else still. A full hour later they were talking enjoyably
about matters of no conceivable relationship to large patches of foam
seen floating on the ocean's surface where the water was forty-five
hundred fathoms deep.

Davis came to a halt beside them.

"Morton's just been talking to me from Thrawn Island," he said abruptly.
"He's very much upset. It's about that prospective bolide that was
spotted from Palomar. It's been right there for two hours."

Terry waited.

"Morton," said Davis, "would like us to try to photograph it when it
comes in, back where the _Pelorus_ was this morning."

Terry stared. Shooting stars are not rare. On an average summer night
anybody can see at least three in an hour's watch of any one quarter of
the sky. Bolides are a rare kind of shooting star. Still, many people
have seen one or two in their lifetime. But nobody plans ahead of time
to observe a bolide, and still less does anybody ever plan in advance to
watch a meteorite arrive on the earth's surface, whether on land or sea.
It is simply not thinkable.

"We'll go back and try," said Davis. He seemed embarrassed. "Morton says
there's no sense to it at all, and that if we do get photographs they'll
be considered fakes. He's really wrought up. But he asked if I thought I
could get a plane out from Manila to watch it fall--if it comes. I'm
going to try that too." He added, more embarrassed still, "Of course
nobody'd pay attention if I explained why the plane should go there.
I'll have to say that I'm just looking for something else peculiar to
happen at that spot. The _Pelorus_ must have already reported that one
peculiar thing has happened."

Terry opened his mouth, and closed it again. Davis went away.

"You had an idea," said Deirdre accusingly. "What?"

"I was thinking of Horta," said Terry. "Police Captain Horta. A very
honest man with no scientific knowledge at all. Nobody with a scientific
education would pay any attention, but I could get him to tell a few
others who know as little as he does, and if the damned thing does turn
up, there'll be proof it was foretold. If it doesn't arrive--" Terry
shrugged, "I've no scientific reputation to lose."

"Wonderful!" said Deirdre warmly. "But you wouldn't have proposed it but
for me! I'll put things in motion!"

She vanished. Within minutes the _Esperance_ came about in a wide
semicircle and headed in the direction from which she had just come.
Deirdre stayed out of sight for a long while. When she came up it was to
tell Terry that Nick was calling on the short-wave set. He'd raised the
flattop in Manila Bay. The flattop had raised the shore. Telephone calls
were being made to here and there and everywhere to get Horta to a
short-wave station to take a call from Terry.

It was near sunset when the complicated call was ready and Horta's voice
came into a pair of headphones Terry was wearing in the _Esperance's_
radio room.

"I need," said Terry slowly, "to have a number of people in Manila know
now of something that's going to happen out at sea tonight. They'll be
needed to testify that they knew of the prediction before the event. Can
you arrange it?"

"_Por supuesto_," said Horta's voice cheerfully. "Are we not _amigos_?
What is the prediction and who should know?"

"The prediction," said Terry doggedly, anticipating disbelief and
protest, "is that at twelve minutes after nine o'clock tonight a large
meteorite will fall into the sea where--hmm--where _La Rubia_ catches
her fish. No, you'd better not locate it that way. I'll give you the
position."

Davis, standing by, wrote the position in latitude and longitude and
handed it to him. He read it into the transmitter.

"Have you got it?" he demanded. "Is it written down?"

"Ah, yes," said Horta tranquilly. "I will see that they make a
memorandum of the matter. Shall I tell three or four persons, or more? I
have news for you also. Jimenez...."

"Look here!" said Terry sharply. "I want this thing to be past all
doubt! Everybody who's ever been worried about _La Rubia_ should know
about this! There should be no possible doubt about it! But there should
be disbelief, so people who don't believe will try to verify that it
didn't happen, so they can crow over the people who thought it would, or
might."

"Ah!" said Horta. "You wish you stick out the neck! It is serious! Now
tell me again!"

"At twelve minutes after nine tonight," said Terry doggedly, "A shooting
star will fall into the sea at...." He named the latitude and longitude
Davis had given him. "That is where _La Rubia_ catches her fish."

"A shooting star will fall there?" protested Horta. "But who knows where
they fall?"

"You do," said Terry. "This one, anyhow. Now, will you see that a number
of people know about it?"

"It is cr-azy!" objected Horta. Then he said, "I will do it."

The short-wave call ended, with Horta too much disturbed to refer again
to Jimenez.

By sunset Doug had gotten out the gun-cameras. Doug held an impromptu
class on deck, showing the other crew-cuts exactly how to aim the
cameras and expose the films, and what button to press to change film
automatically between shots. He was unhappy because he did not know how
bright the object to be photographed would be, for his lens-settings. He
was even more unhappy because the bolide might travel at practically any
angular velocity, so he didn't know how to set the shutters. But the
focus would be infinity, and if he used the fastest possible film, he
could stop most motion with a hundredth second exposure.

Instead of reaching Thrawn Island shortly after sunset, then, the
_Esperance_ was back above the place where the dredge had been dropped
and the bathyscaphe wrecked. The _Pelorus_ was gone. The people on board
that ship must have been very upset. The bathyscaphe had cost more money
than is usually allotted to most scientific researchers, and now it was
smashed. How would they justify themselves? They could hardly blame the
_Esperance_.

The yacht sailed in a closed pattern over this area of the Luzon Deep.
Deirdre served dinner on deck. Stars shone down almost instantly after a
sunset of unusual magnificence, even for the China Sea. Tony brought his
guitar aft, and a contagious feeling of exhilaration spread about the
_Esperance_ and an improvised party took place on deck. Maybe the mood
for festivity arose from the realization that at least nine-tenths of
the world's population would have graded them as lunatics, had it known
their project for the evening.

It would have been unjust, of course. Terry reflected that it had not
been their idea to make an appointment with a shooting star. They were
doing it out of some sort of professional courtesy, "from one set of
crackpots to another," Terry phrased it in his own mind. It was a wild
attempt to secure proof of the starkly impossible. So there was chatter,
singing, and some dancing. The high spot was perhaps the time when Jug
bashfully serenaded the rigging and the stars above it with howling
melodies he'd learned in college.

Eventually, Nick went down to the short-wave set. Doug passed out the
gun-cameras again, after checking each one. Nick popped his head out of
the hatch.

"Dr. Morton's been calling like crazy," he reported. "The bolide's made
four orbital turns, coming in all the while. It ought to touch the
atmosphere next time around. ETO is nine-twelve-seventeen-seconds. I
told him we're all set."

His head disappeared.

"Don't forget!" Doug said anxiously. "The cameras will feel like
shotguns but don't lead your target! And don't forget to press the
film-changer!"

Terry lifted his gun-camera experimentally. It did feel like a shotgun.
And then, suddenly, he disbelieved everything: the purpose of the
_Esperance's_ original investigation; the phenomena that had been
observed; the guesses that had been made. It was pure insanity! He felt
a quick impatience with himself for becoming entangled in anything so
ridiculous.

Deirdre leaned toward him and whispered forlornly, "Terry! It's
dreadful! I've just had an attack of common sense! What are we doing
here? We're crazy!"

He put his hand consolingly over hers. The act was unpremeditated and
the sensation was startling. He found that they were staring at each
other intently in the starlight.

"I think ..." said Terry, unsteadily, "that it's very sensible to be
crazy. We've got to ... talk this over."

Deirdre smiled at him shakily.

"Y-yes, we will."

Then Davis pointed out positions for the camera operators. The bolide's
course should be three hundred fifty degrees, not quite on a north-south
line. It might land short of, or beyond, the _Esperance_. Or it might
pass many miles to the east or west. Dr. Morton needed as many pictures
of it against recognizable stars as could possibly be secured.

Suddenly, there was a faint, dull rumbling in the heavens. It grew
louder. Presently, cruising lights appeared in the sky. They maintained
a fixed relationship to each other. They looked like moving stars,
flying in formation from star-cluster to star-cluster.

Nick popped abovedecks again.

"The planes just called us," he reported. "They've just had a Loran
position-check and they're on the mark. They've got orders to observe
any unusual phenomena occurring around nine-twelve P.M., Manila time.
Using civilian terminology, it sounds like they're saying the Philippine
Government asked them to come out and take a look."

"It's five after nine now," said Davis.

The _Esperance_ headed into the wind. Her bow rose and fell. Waves
washed past, and roarings trundled about under the stars overhead, and
very tiny lights moved in a compact group across the firmament.

Time passed.

At twenty-two seconds after nine-twelve--which is to say at twenty-one
hours, twelve minutes, twenty-two seconds--a light appeared in the sky
from the north. It grew steadily brighter. It suddenly flared very
brightly indeed, then dimmed, and continued to rise above the horizon.
Seconds later it flared again, very briefly.

Terry found himself aiming the gun-camera. He pulled trigger and changed
film and pulled trigger and changed film.

The bright light ceased to climb. It grew steadily brighter and
brighter, and then it flared for the third time--Terry's mind asked
skeptically, 'Braking rockets?'--and the light was so intense that the
cracks in the yacht's deck-planking could be seen. Then the extra
brilliance vanished, and suddenly the moving light was no longer white,
but reddish.

Terry aimed again and fired the gun-camera.

The light passed almost directly overhead. Terry had the impression that
he felt its heat upon his skin.

It plunged into the sea two miles beyond the _Esperance_. The shock-wave
caused by the impact tapped on the yacht's side-planking a few seconds
later. Starlight shone upon a plume of steam.

Then there was nothing but the noise of the circling planes above. Then
a sound, as of thunder. It disappeared northward. It was the sound of
the bolide's passage, arriving after the object itself had dived into
the sea.

The people on the _Esperance_ were dumfounded. Nick went below and came
up again a few minutes latter.

"The planes were calling," he reported. "They say they noted the unusual
phenomenon. They ask if they should stay around for something else."

"I think," said Davis caustically, "that that's all that's scheduled
just now. Tell them so."

The _Esperance_ went on steadily again, a trifle west of north. Davis
was below, talking via radio to Dr. Morton at the satellite tracking
base.

Terry and Deirdre went to look for a place where they could talk over
something privately. It was of enormous importance to them, but it was
not connected with fish or meteorites or plastic objects or anything at
all but the two of them. And to them the yacht seemed crowded with
people, even though there was nobody else abovedecks but one of the
crew-cuts at the wheel.

When the _Esperance_ entered the lagoon the next morning, though, their
private talk had evidently come to a satisfactory conclusion. Deirdre
smiled at Terry without any reason whatever, and he looked at once smug
and embarrassed and uneasy, as if he possessed a new status to which he
was still unaccustomed.

The recorder, trailing a submarine ear overboard, had duly reported the
presence of the hum in the water, just outside the lagoon. It had not
been operating for forty hours or thereabouts. During that time the fish
inside could go out of the lagoon, if they chose. And other fish could
come in. Terry said suddenly, as the yacht went under power toward the
tracking station wharf, "Suppose there was a cone of noise just outside
the lagoon, and the flanks of the submarine mountain under us were
included in the cone? And suppose the cone grew smaller, like the other
one. What would happen?"

Deirdre shook her head, smiling at him.

"The fish," said Terry, "could escape into the lagoon."

"Probably," agreed Deirdre.

"And if fish could be driven downward along a certain path," said Terry,
"the way we saw it happen, why, fish could be driven up in a certain
path, too."

"Obviously," said Deirdre.

"So if something wanted to replace the fish in the lagoon, or to add to
their number, why, it would puncture their swim bladders far, far down,
and then drive them up to the surface and into the lagoon, and then keep
the noise going to keep them inside."

"Is this a new idea?" asked Deirdre.

"N-n-o," admitted Terry. "I've had it for some time."

"So," said Deirdre, "have I."

The _Esperance's_ engine stopped, and she floated to gentle contact with
the wharf. Members of the tracking station staff made the yacht fast.
With others, Dr. Morton came on board. His expression was the picture of
unrelieved gloom.

"I'm in a nice spot!" he told Davis. "I predicted a second bolide
correctly! I had to use a different retardation factor to make the math
come out right. Now I'm asked to explain that! How can I tell them I
knew where it would fall, and only had to compute when?"

"Come below and look at the pictures we got," said Davis.

They disappeared down the after-cabin hatch. Terry knew about the
pictures. Doug had developed them with sweating care, developing each
negative separately and adjusting the development-time to the varying
exposures of the bright object.

There was a total of twenty reasonably good pictures of the bolide, from
its first appearance to its plunge into the ocean, two miles from the
_Esperance_. Doug had enlarged some of them. There were distinct
star-patterns in most. In nearly all, though, the object was more or
less blurred by its own motion. In those taken when it flared most
brightly, the blurriness was especially marked. There was only one
picture of professional, if accidental, quality, and it was the least
convincing of all. It showed the fore-part of a conical shape traveling
point-first. Nobody would conceivably believe that it was a meteorite.
It looked artificial.

Terry and Deirdre, as it happened, stayed on deck. The people of the
tracking station made a babbling uproar. It appeared that the most
important event in history, as history was viewed on Thrawn Island, had
taken place the night before. It was revealed--Terry had not suspected
his own success--that in asking Horta to see that there was
foreknowledge of a meteoric fall, Terry had arranged for the matter to
be taken immediately to high Philippine Government officials. The
American flattop, at their request, had sent planes to the place of the
fall, with orders which were enigmatic only until the descending object
appeared. Then every man in every plane knew that he'd been sent there
to see it.

So there could be no question but that Dr. Morton had predicted it. That
meant that he knew more about meteoric objects than anybody else in the
world. What he had to say was of vast importance, and Thrawn Island
shared in his achievement. But it was a strictly professional triumph.
The news would not break in the newspapers. No ordinary reader would
believe in it. And nobody anywhere would believe in Morton's knowledge
of the place of the fall before he began to calculate.

Terry observed that the people of Thrawn Island were definitely no
longer interested in fish. They'd kept their eyes open for oddities
because a deep-sea fish with a plastic object attached had been caught
in the lagoon a long while before. They'd been intensely interested when
Terry herded all the lagoon fish into one small inner bay, and they
speared sixty fish that had no business being at the surface. They'd
found eight more plastic objects. Such things had been interesting, if
not important. But now the head of the Thrawn Island staff had computed
the place and time of arrival of a meteoric mass from space! And he did
it when that mass was five thousand miles out! From a professional
standpoint, this was stupendous! They tried to make Terry see how
important it was.

Davis and Morton came up from below. They headed for the shore. The
crew-cuts trailed off to the land with most of the visitors. Only
Deirdre and Terry remained on the yacht, with a mere short-wave operator
from the island.

"We're going to have a fancy lunch, with champagne and speeches," the
operator said hopefully. "You'll come?"

"Naturally!" said Terry. "But first we're going swimming. We haven't had
a chance to be overboard since the last time we were here."

"We'll be back in time for lunch," Deirdre assured the operator, "but
swimming here is so wonderful! We've been talking about it for days!"

She went below to change. The operator shrugged. After a further attempt
to interest Terry in the celebration of an astronomical first, he went
ashore. Terry went with him to get the outboard motorboat he and Deirdre
had used before. He was already wearing swimming trunks.

A little later the small boat putt-putted away from the _Esperance_ upon
the glassy-rippled waters of the lagoon.

There was a very great tranquillity everywhere. The booming roar of the
surf came from unseen rollers on the reef outside. Seabirds squawked.
Palms along the edge of the lagoon waved their fronds very, very gently.

"How far will you go before we swim?" asked Deirdre. "All the lagoon's
perfect. One place is as good as another."

He cut off the motor.

"Hmmm. There's a deep place yonder," he observed. "That's where I went
with the aqualung and speared the freak fish. Stay away from it."

She jumped over in a clean dive. He joined her in the water. She came
up, blowing bubbles.

"All right, Terry. What are your troubles?"

"That bolide bothers me," he told her. "It had a specific destination!
It was meant to hit the water over the Luzon Deep!"

She dived again. This time Terry followed her. The underwater world was
beautifully bright, with ripplings making everything seem to shimmer
because of the changing light. When they came up again Deirdre said,
"Funny!"

"It had a purpose!" insisted Terry. "There were others before it, and
they had a purpose too! That's not funny!"

"I didn't mean that," said Deirdre. "I meant ... just now, under the
water.... What's that?"

There was a swirling at the surface, some tens of yards away. It was not
the curling eddy made by a fish about to break surface. It was too big a
disturbance for that. It looked as if something stirred, barely
submerged, but something very large. Terry, staring, thought of a
porpoise cavorting just below the ripples. Or perhaps a shark. But
sharks and porpoises are too small to have made this eddying. It
reappeared.

"Get in the boat!" snapped Terry. "Quick!"

While she climbed in he let himself sink, his eyes open. There was a
clouding of the water underneath, where the surface-disturbance had
been. It was mud from the bottom which had been stirred up. He could see
nothing clearly through it, though nearby and around him he could easily
see the colorings of coral and fan sponges, and he could see small fish
darting here and there.

He broke surface. Deirdre bent anxiously over the gunwale.

"What is it?"

"I don't know," he said curtly. "But give me a fish spear."

"You won't...."

"I just want to have something in my hand," he told her impatiently,
"while I look."

He took the spear she handed him, and sank once more. Again something
moved in the deeper part of the lagoon. It was a fretful motion, as if a
creature or creatures tried to burrow away from the light shining
through the water. Whatever moved, a thick cloud of debris from the
bottom floated all the way up to the surface.

Terry came up for air.

"There's something queer there," he said shortly. "I don't know what."

He went under and swam cautiously nearer to the disturbance. He was
within a few feet of the curling cloud of obscurity when something like
a gigantic worm came out of it. Or maybe it was like an elephant's
trunk, only no elephant ever had a trunk so huge. It was a dull and
glistening writhing object. Its end was rounded. The tip of the
worm-like thing must have been a foot in diameter, and it came out of
the mud cloud for four feet, then six, then, fifteen feet. It thickened
only slightly in that length. It groped blindly in the brightness.

Terry swam back quickly, and the object reared up and made a groping
sweep through the clear water. Some peculiar white disks suddenly
appeared on the underside of the long tentacle. They looked like
sucker-disks, able to grip anything at all. The monstrous tentacle
fumbled for Terry, as if guided by the pressure-waves his movements
generated.

Terry froze. Deirdre moved in the boat almost directly overhead.
Something clanked in the boat and he heard it. The boat was probably
rocking, making the pressure-waves that a creature from the abyss would
depend upon for guidance where eyes would not serve at all.

The thick, bulging tentacle reached toward the sound at the surface, now
ignoring Terry, though he was nearer. He was still. The white
sucker-disks on its under side had several rings of a horny, tooth-like
substance at their rims. The smallest were about four inches wide. The
fumbling object felt blindly in the water. Deirdre stirred again in the
boat. The visible portion of the groping monstrosity was already longer
than the boat. The whole creature would be enormous! If this groping arm
rested upon the gunwale of the boat, it could easily swamp it.

It groped for the boat, coming horribly out of a cloud of mud. It
reached out. In another instant it would touch....

Terry plunged his fish spear into the worm. It jerked violently. There
were enormous thrashings. Other similar white-disked arms thrust into
view, fumbling somehow angrily for the creature--Terry--which had dared
to attack it.

He darted for the surface. Something unspeakably horrible touched him,
but it was the smooth and not the suckered side of the groping worm.
Terry's head was now above water. He grasped the gunwale to pull himself
in, in a fever of haste. But the thing that had touched him before came
back. It grazed his leg, for just a second. Where it touched, his flesh
burned like fire.

"Start ... motor!" gasped Terry. "Get away!"

Something touched the stern-board of the boat. Deirdre pulled the
starter of the motor.

"Get in!" she said tensely. "Quickly!"

She saw him, straining every muscle by pure, agonized instinct against
the irresistible force of whatever clung to his skin. The horrible
tentacle stretched, and part of its length took a new grip. It crawled
upon him.... Deirdre saw the look on his face.

She snatched up the second spear and stabbed past him, into the crawling
beast. There was a most violent jerking. She stabbed again. She panted.
She gasped. She stabbed and stabbed, sobbing with fear and horror. And
Terry tumbled in over the gunwale, released. As soon as he fell onto the
floor-boards he painfully dragged himself toward the motor at the stern.
Something bumped the boat underneath. Terry pulled the starter and the
motor suddenly roared. But the boat didn't start immediately, and it
jerked once more. The whirling propeller-blades had touched one of the
groping tentacles and cut it. Tumult arose.

The boat surged into motion and Terry, with clenched teeth, sent it into
a crazy, skidding turn to avoid a surface swirl, and then another
frantic swerve when something showed momentarily above the surface. The
boat zig-zagged along. A grisly, writhing object rose above the water,
flailing, a fish-spear sticking in it. The small, skimming boat dodged
and twisted at its topmost speed.... It suddenly straightened out and
almost flew across the water toward the land.




_Eight_


Echoes of the outboard's roaring motor came back from the trunks of palm
trees that lined the lagoon's shore as the tiny boat raced across the
water. Deirdre was ashen-white. She turned her eyes from the water, and
they fell on the round raw places on Terry's leg where the sucker-disks
had bruised it horribly. She shuddered. She still had the sensation of
being pursued by the monster. Back where Deirdre's spear had finally
liberated Terry, startled and convulsive motions continued, followed by
a final gigantic splash. Terry drove the boat on at top speed.

The monster sank again in the spot where the lagoon was deepest. It had
come from depths where there was no light; from an abyss where blackness
was absolute. Now, having lost its victim, it returned peevishly to such
darkness as it could secure.

Terry said curtly, as the small boat raced for the _Esperance_ and the
wharf, "That creature was driven up from the Luzon Deep into the lagoon
to replace the gadget-carrying fish we speared!"

Deirdre stammered a little.

"Your l-leg.... You're bleeding...."

"I'm pretty well skinned in a couple of places," he said shortly.
"That's all."

"Could it be poisonous?"

"Poison," said Terry, "is a weapon for the weak. This thing's not weak!
I'm all right. And I'm lucky!"

"I'd have jumped over with my spear, if ..."

"Idiot!" said Terry gently. "Never think of such a thing! Never! Never!"

"I wouldn't want to l-live--"

A new reverberating quality came into the echoes from the shore. The
pilings of the wharf were nearby, now. They multiplied the sounds they
returned. The _Esperance_ loomed up. Terry cut off the motor, the little
boat drifted to contact, and Deirdre scrambled to the yacht's deck, and
then took the bow line and fastened it. This was absurdly commonplace.
It was exactly what would have been done on the return from any usual
ride.

"Go tell the others what we found," said Terry. "I'm going to see if
there's more than one of those things around."

"Not ..."

"No," he assured her. "I'm only going to use the fish-driving horn."

Deirdre looked at him in distress.

"Be careful! Please!" She kissed him suddenly, scrambled to the wharf,
and set off at a run toward the shore. Terry stared hungrily after her.
They'd come to a highly personal decision the night before on the
_Esperance_, but it still seemed unbelievable to him that Deirdre felt
about him the way he felt about her.

He went forward to set up the fish-driving combination. One part of him
thought vividly of Deirdre. The other faced the consequences that might
follow if the bolides were not bolides, and if the plastic gadgets and
the nasty-sounding underwater hums were products of an intelligence
which could make bolides change their velocity in space; which made them
fall in the Luzon Deep in the China Sea and nowhere else.

He set up the recorder with its loop of fish-driving hum. He put the
horn overboard, carefully oriented to spread its sound through all the
enclosed shallow water of the lagoon. He turned the extra amplifier to
maximum output, to increase the effectiveness of the noise, and turned
on the apparatus.

The glassy look of the lagoon-water vanished immediately. Fish leaped
crazily everywhere, from half-inch midgets to lean-flanked predators a
yard and more in length. There was no square foot in all the shallows
where a creature didn't struggle to escape the sensation of pins and
needles all over its body. And these pins and needles pricked deep.

Flying-fish soared crazily, and they were the most fortunate because so
long as they flew, the tormenting water-sound did not reach them. But
many of them landed on the beach, and even among the palms.

In the spot where blind and snakelike arms had tried to destroy Terry
and Deirdre, the lashing and swirling was of a different kind. Something
there used enormous strength to offer battle to a noise. The water was
whipped to froth. Twice Terry saw those rope-like arms rise above the
water and flail it.

This particular sort of tumult, however, appeared only in one spot. So
there was only one such creature in the lagoon.

When Davis and the others came down from the tracking station, Terry
turned off the horn. He was applying soothing ointment to the raw flesh
of his leg.

"There's a monstrous creature out there," he said evenly when a
white-faced Davis demanded information. "Heaven knows how big it is, but
it's something like a huge squid. It may be the kind that sperm whales
feed on, down in the depths."

Others from the tracking station arrived, panting.

"Oh! I'm tired of being conservative!" added Terry fiercely. "I'm going
to say what all of us think! There's something intelligent down at the
bottom of the sea, five miles down!"

He glared challengingly around him.

"Who doesn't believe that?" he demanded. "Well, the reporting gadgets
don't report any more. We killed the fish that carried them. So that
whatever-it-is down on the sea-bed has very cleverly sent up something
we ignorant savages wouldn't dare to meddle with! We would be terrified.
But we'll show _it_ what men are like!"

Dr. Morton said gently, "Perhaps we should notify the _Pelorus_. The
biologists on board there...."

"No!" said Terry grimly. "I have a private quarrel with this monster. It
might have killed Deirdre! And Davis already tried to tell those
biologists something! Tell them about this, and they'll want proofs they
wouldn't look at anyhow. We'll handle this ourselves! It's too important
for them!"

"Much too important," said Deirdre firmly. "The shooting stars aren't
shooting stars and there's something down in the depths just like Terry
says. He's right that we can't consider sharing our world with--beings
that come down from the sky, even if they only want our oceans and don't
care about the land. He says that we wouldn't get along with creatures
that know more than we do, and we would especially resent any space
ships coming uninvited to start colonies on our world while we're not
advanced enough to stop them! If that's what they're doing, they have to
be fought from the very first instant to the very last moment there's
one of them hiding in our seas! Terry's right!"

"I haven't heard him say any of those things, young lady," said Morton
drily, "but they're true. And I don't like the idea of a sea monster
being in the lagoon anyhow. Especially one that tries to kill people.
Still, fighting it...."

"There are a couple of bazookas on the _Esperance_," said Terry sharply.
He looked at Davis. "If you're willing to risk the yacht, we can drive
the beast aground, or at least to shallow water, with the submarine
horn. Then the bazookas should be able to destroy it. Will you take the
risk?"

"Of course you'll use the _Esperance_," said Davis. "Of course!"

"Then I'll want," said Terry, unconsciously taking command, "somebody at
the engine and somebody at the wheel. I'll run the horn. But, frankly,
if that monster lays one sucker-arm on the _Esperance_, it may be
good-bye. Any volunteers?"

In minutes the _Esperance_, her engine rumbling, pulled away from the
dock. She had on board all her original company except Deirdre--firmly
left ashore by her father and Terry--and in addition she carried Dr.
Morton and the most enthusiastic amateur photographer of the tracking
station staff. He was shaky but resolute, and was hanging about with an
imposing array of cameras, for both still and motion pictures. The
_Esperance's_ sails were furled and she went into battle under bare
poles. Davis was busy manufacturing improvised hand grenades for himself
and Morton.

The sun was nearly overhead. Terry asked Morton questions about the
lagoon. They finally chose a minor inlet as the place to which the
creature must be driven, if possible. There it could be immobilized by
the intolerable sound from the recorder. There it could be destroyed.

"I wonder," said Morton wryly, "if I can present a dead giant squid as
part of the explanation for my computed orbits for the last two
bolides!"

The _Esperance_ moved steadily toward the place where Terry had nearly
been killed.

The enterprise was risky. The _Esperance_ was sixty-five feet long. The
creature it was to attack was much larger, and if one of its kind had
crushed the bathyscaphe, it had sufficient strength and ferocity to make
a battle cruiser a much more suitable antagonist. But the true folly of
the effort was its purpose.

It all started when a fishing boat--_La Rubia_--went to sea and caught
remarkable quantities of fish, of which four specimens had had plastic
artefacts fastened to them. Then Terry began checking on certain noises
he heard in the sea which provoked an incomprehensible crowding of
millions of fish into a small area, from which they swam down to depths
where they could not survive. Now the killing of this squid was supposed
to cast a light on the mystery of the nine bolides which had fallen into
a particular part of the ocean.

Terry had the undersea horn turned vertically so that it would transmit
a blade of sound wherever he aimed it, instead of spreading all through
the lagoon. He turned it on.

The water before the _Esperance_ suddenly speckled and splashed from the
maddened leaps of fish of every possible size. He turned it off. He
aimed it where the ripples showed the presence of something huge beneath
the surface. He turned it on again.

There were convulsive writhings. A long tentacle emerged briefly and
then splashed under again. The writhings continued. Terry adjusted his
aim. Crazy leapings of smaller creatures showed the line of the
sound-beam, as tracer-bullets show the paths of bullets from a machine
gun. He cut off the sound for an instant and turned it on again at full
volume, pointed where the monster must be. There was explosive tumult
underwater. Huge arms flailed above the surface. But once again the
creature fled.

The _Esperance_ followed slowly, now. The monster had reacted to the
stinging sound-beam as if cowed. But it was a deep-sea creature. It did
not know how to move when squeezed into a shallow water which hampered
its movements. It seemed frightened to discover itself trapped between
the lagoon-bottom and the surface. And it was dazzled by the brightness
to which it had been driven. Left unattacked, even for an instant, it
tried to burrow away from the light, and again it made a dense cloud of
mud from the bottom. Then it became quiet, as if hiding.

Grimly, Terry lanced it with the painful noise. The water frothed.
Monstrous tentacles appeared and disappeared, and once part of the
creature's body itself emerged. It was cornered into a minor inlet, and
there the water grew more shallow and the monster did not want to go to
where its motions would be even more confined.

It seemed to flow into the deepest part of the miniature bay. It was as
if it felt certain of a haven there. When the tormenting noise-beam
struck again, the abyssal monster flung itself about crazily. A
terrible, frustrated rage filled it. Its arms fumbled here and there,
above water and below. It hauled itself upright so that a part of its
torpedo-shaped body broke through the surface. The monster was mad with
fury. It plunged toward the _Esperance_, not swimming now, but crawling
with all its eight legs in water too shallow to submerge it. Its effort
was desperate. It lifted everything from the water, and splashed
everything down again, all the while crawling toward its enemy.

Terry saw Nick and Jug steady the aim of their bazookas. Davis ran
toward the bow with hand grenades. The huge squid came crawling, and
with every foot of advance the pain-noise grew more unendurable.
Suddenly the creature uttered a mooing cry and retreated. The cry was
like the mooing noise Terry had picked up from the depths.

It went aground. It struggled to climb ashore, to do anything to escape
its tormentors. It foamed and splashed....

Despairing, it turned to face its tormentors. Its body reared almost
entirely out of the water, now. It sagged flabbily. It reeled as its
arms strained. Its eyes rose above the surface, blinded by the light.
They were huge eyes. Squids alone, among the invertebrates, have eyes
like those of land beasts. They flamed demoniac hatred. A beak appeared,
not unlike a parrot's, but capable of rending steel plates. The beak
opened and closed with clicking sounds that were singularly horrifying.
It snapped at the yacht, which was beyond reach. One of the tentacles
wrenched violently at something. It gave. The arm rose above the water.
A thorny mass of branched coral flew through the air and splashed close
beside the _Esperance_.

"Shoot!" said Terry, somehow sickened. "Dammit, shoot!"

Nick and Tony aimed closely. The bazookas made their peculiar,
inadequate sounds. The bazooka-shells, like small rocket-missiles, sped
through the short distance. They struck. Their shaped charges detonated,
again with inadequate loudness. They did not explode in a fashion to
tear the creature to bits. Instead, they sent lancing flames a thousand
times more deadly than bullets into the squid's flesh.

It fought insanely. It uttered shrill cries. Its arms tore at its own
wounds, at the water, at the lagoon-bed as if it would rend and shatter
all the universe in its rage.

The bazookas fired again and again.

It was the eighth missile from the bazooka which ended the battle. Then
the enormous body went limp. Its horny beak ceased to try to crush all
creation. But the long, thick, sucker-disked arms thrashed aimlessly for
a long time. Even when they ceased to throw themselves about, they
quivered and rippled for a considerable period more. And when it seemed
that all life had left the gigantic beast, and the men from the
satellite-tracking station stepped on the monstrous body, it suddenly
jerked once more, in a last attempt to murder.

The squid's body, without the tentacles, was thirty-five feet long. The
largest squid, the Atlantic variety, captured before had a mantle no
longer than twenty feet. That relatively familiar creature,
_Architeuthis princeps_, came to a maximum total length of fifty-two
feet. Counting the two longest arms of this one, it reached eighty. It
could not possibly swim in water less than six yards deep. It did not
belong in a coral lagoon, but it was there.

It was close to sunset when the last tremors of the great mass of flesh
were stilled. Terry was in no mood for eating, afterward. He skipped the
evening meal altogether, and paced up and down the veranda of the dining
hall, at the satellite-tracking station. Inside, there was a clatter of
dishes and a humming of voices. Outside, there was a soft, warm, starlit
night. The surf boomed on the reef outside the lagoon.

Deirdre came out and walked quickly into Terry's arms. She kissed him
and then drew back.

"Darling!" she said softly. Her voice changed. "How is your leg? Does it
still hurt?"

"It's nothing to worry about," said Terry. "I'm worried about something
else. Two things, in fact."

"Name one!" said Deirdre, smiling.

"I'd like to get married soon," said Terry ruefully.

"To whom?" she asked, jokingly.

"But I have to have a business or an income first. I think, though, that
with a little hard work I can start up my _especialidades electronicas y
fisicas_ again, and if you don't mind skimping a little ..."

"I'll adore it," said Deirdre enthusiastically. "What else would I
want? What's the other thing you worry about?"

"That monster," said Terry with some grimness.

"Pouf!" said Deirdre. "You've killed it!"

"I don't mean that one," said Terry more grimly. "I mean the one that
sent it. I wish I knew what it is and what it intends to do!"

"You've already found out more than anybody else even dared to guess!"
she protested.

"But not enough. We've stirred it up. It sent small fish in the lagoon
here and elsewhere to report back to it. We can't guess what the fish
reported, but we know some of it was about human beings. Whatever is
down at the bottom of the sea must be interested in men. Remember? It
made a patch of foam that swallowed up one ship and all its crew. It's
interested in men, all right!"

"True, but...."

"We dropped the dredge, which implied that we were interested in it. The
bathyscaphe indicated more interest on our part. To discourage that
interest--or perhaps in self-defense--it wrecked the bathyscaphe."

"It, Terry?" asked Deirdre. "Or _ellos_, they?"

"They," he corrected himself coldly. "We killed the fish that were
reporting men's doings from here. That was insolence on our part. So the
hum at the lagoon entrance went off and, after two nights, started
again--and then this huge squid was found in the lagoon. It should have
been able to defend itself against us. It was sent up here because it
was capable of defending itself! But we've killed it just the same. So
now what will come up out of the depths? And what will it do?"

Deirdre said firmly, "You'll be ready for it when it comes!"

"Maybe," said Terry. "Your father once mentioned an instrument he'd like
to have to take a relief map of the ocean bottom. Changed around a
little, it might be something we need very badly indeed. The horn we've
got is good, but not good enough. I'll talk to the electronics men
here."

There was a noise of scraping chairs, inside the dining hall. People
came out, talking cheerfully. There was much to talk about on Thrawn
Island today. The killing of a giant squid had been preceded by a
specific guess that linked it to meteoric falls in the Luzon Deep.
Logically, the excitement had grown.

Terry found his electronics specialists, and explained to them the type
of apparatus he was interested in. He asked if it was included in the
island's technical stores. He wanted to assemble something capable of
emitting underwater noises of special quality and unprecedented power.
There is not much power involved in sound through the air. A cornet
player manages with much effort to convert four-tenths of a watt of
power into music. A public-address system for a large area may give out
fifteen watts of noise. Terry described a device which could use a small
amount of power, serving as a sonar or a depth-finding unit, and then,
with the throw of a switch, turn kilowatts into vibrations underneath
the sea. If powerful and shrill enough, such vibrations could be lethal.

A technical argument ensued. Terry's demands were toned down to fit the
equipment at hand. Then three men went with him to the island's
workshop. They took off their coats and set to work.

Three hours later someone noticed an unknown vessel making its way into
the lagoon. She was stubby and small, and had short thick masts with
heavy booms tilted up at steep angles. Her Diesel engines boomed
hollowly, louder than the surf. As she entered the lagoon, a searchlight
winked on and flicked here and there. It finally found the wharf where
the _Esperance_ was moored.

Men of the tracking station staff went down to the wharf to meet the
small row boat that was now coming ashore.

A short, stout, irate fishing boat skipper waved his arms and shouted
angrily. What had _los americanos_ done to keep _La Rubia_ from catching
fish? Why had they changed the arrangement by which the starving wives
and children of _La Rubia's_ crew were fed? He would protest to the
Philippine Government! He would expose the villainy of _los americanos_
to the world! He demanded that now, instantly, the original state of
affairs be restored!

A fish leaped out of the water nearby. Where it leaped, and where it
fell back, bright specks of luminosity appeared. Even the ripples of the
splashes glowed faintly as they spread outward. The skipper of _La
Rubia_ stared. And now the people of the island realized that the look
of the water was not altogether commonplace. Little bluish flames under
the surface showed that many fish darted there. There were more fish
than usual in the lagoon. Many more. The lagoon had suddenly become a
fine place to catch fish. Some care would be needed, of course. There
were doubtless coral heads in plenty. But still ...

The skipper of _La Rubia_ abruptly returned to his fury and his
protests. _La Rubia_ had gone to the place where she always found fish.
Always! There was a humming in the water there, and fish were to be
found in quantity. But yesterday the American ship had been there, and
also this very yacht! _La Rubia_ stayed out of sight lest the
_americanos_ learn her fishing secrets. But it was useless. When the two
American ships were gone, there was no longer a humming in the sea and
no more fish for the crew of _La Rubia_ to capture for their hungry
wives and children. And therefore he, Capitan Saavedra, demanded that
the _americanos_ restore the previous state of affairs.

Davis would have intervened, but the chubby skipper erupted into wilder
and more theatrical accusations still.

Let them not deny what they had done! Fish were always to be found where
there was a humming in the sea that _las orejas de ellos_ heard and
reported to him. But that humming was not in its former place. It was
here! At the entrance of the lagoon! The fish were here, also! _Los
americanos_ had moved the fish so the crewmen of _La Rubia_ could not
feed their wives and children. _Los americanos_ wished to take all the
fish for themselves! But fish were the property of all men, especially
fishermen with starving wives and children. So he, Capitan Saavedra,
would fish in this lagoon, and he defied anyone to stop him.

"Certainly," said Terry. "_Seguramente!_" He added in Spanish: "We'll
lend you a short-wave contact with Manila to make any complaints you
please. I'm sure all the other fishing boats will be glad to hear where
you've been catching fish, and where you've found the fish have moved
to! Calm yourself, Capitan, and help yourself to the fish of the lagoon,
and any time you want to call Manila we'll arrange it!"

He moved away. He went back to the electronics shop, while Morton and
Davis and the others talked encouragingly to Capitan Saavedra. Presently
they suggested that he accept their hospitality, and the Capitan and his
oarsmen went up to the dining hall, where they were served dinner, and a
more friendly mood developed. In time the Capitan said happily that he
would wait till sunrise to lower his nets, because he didn't want to
risk losing them on the coral heads. A few drinks later the Capitan
boasted about his own system of fishing, as practised by _La Rubia_. The
starving condition of his crew's wives and children ceased to be
mentioned.

In the presence of so accomplished a liar, nobody of the tracking
station staff mentioned a giant squid hauled partly, but only partly,
out of the water. They suspected that he would not believe it. They were
sure that he would top their real feat by an imaginary one. So the four
crew-cuts listened politely, and fed him more drinks, and learned much.

In the workshop the most unlikely device Terry'd described took form. In
effect, it was an underwater horn which was much more powerful than it
looked. Submerged, and with power from a group of amplifiers in
parallel, it would create a tremendous volume of underwater noise. That
sound would run through a tube shaped like a gun-barrel. It would travel
in a straight line, spreading only a little.

The same projection tube could also send out the tentative
beep-beep-beep of sonar gear, or the peculiar noise a depth-finder
makes. So the instrument could search out a distance or find a target,
and then fling at it a beam of humming torment equal to bullets from a
machine gun.

It would have taken Terry, alone, a long time to build. But he had
three assistants, two of whom were very competent. By dawn, they had it
ready to be mounted upon the _Esperance_. It was placed hanging from the
bow, mounted on gimbals, so that it could point in any direction. It was
firmly fixed to the yacht's planking.

There was plenty of activity on _La Rubia_, too, at daybreak. That squat
and capable fishing boat prepared to harvest the fish in the lagoon. She
got her nets over. She essayed to haul them. Some got caught on the
coral heads rising from the lagoon's bottom toward the surface. Capitan
Saavedra swore, and untangled them. He tried again. Again coral heads
baulked the enterprise. The nets tore.

A helicopter came rattling into view from the south. It grew in size and
loudness, and presently hovered over the tracking station. Then it made
a wide, deliberate circuit of the lagoon. At the inlet where the squid
lay almost entirely in the water--but fastened by ropes lest it drift
away--above that spot, the helicopter hovered for a long time. It must
have been taking photographs. Presently, it lowered one man by a line to
the ground. Obviously, the man could not endure any delay in getting at
so desirable a biological specimen. Then the helicopter went droning and
rattling to the tracking station, and landed with an air of weariness.

_La Rubia_ continued to try to catch fish. They were here in plenty. But
the coral heads were everywhere. Nets tore. Ropes parted. Capitan
Saavedra waved his arms and swore.

The _Esperance_ rumbled and circled away from the wharf, and headed for
the lagoon entrance. The singular contrivance built during the night was
in place at her bow. She passed _La Rubia_, on whose deck men
frantically mended nets.

The _Esperance_ passed between the small capes and the first of the
ocean swells raised her bow and rocked her. She proceeded beyond the
reef. The bottom of the sea dropped out of sight. Terry switched on the
submarine ear and listened. The humming sound was to be expected here.

It had stopped. It was present yesterday, and even during the night,
when _La Rubia_ came into the lagoon. But now the sea held no sound
other than the multitudinous random noises of fish and the washing,
roaring, booming of the surf.

Deirdre was aboard, of course. She watched Terry's face. He turned to
the new instrument, and then dropped his hand.

"I think," he said carefully to Davis, "that I'd like to make a sort of
sweep out to sea. It's just possible we'll find the hum farther out."

Deirdre said quickly, "I think I know what you're up to. You want to
survey a large area of the ocean while something comes up. Then you can
direct that "something" to the lagoon mouth by using your sound device,
so the ... whatever-it-is has to take refuge in the lagoon. Since we've
killed the squid...."

"That's it," said Terry. "Something like that happened when we speared
the fish. The squid took their place. Now we've killed the squid. Just
possibly...."

They found the humming sound in the water four miles off-shore. They
traced it through part of a circle. If something were being driven
upward, it could not pass through that wall of humming sound.

"That proves your point," Davis said. "Now what?"

Without realizing it, he'd yielded direction of the enterprise to Terry,
who had unconsciously assumed it.

"Let's go back to the island," said Terry thoughtfully. "I've got a
crazy idea--really crazy! I want to be where we can duck into shallow
water when we try the new projector."

The _Esperance_ swung about and headed back toward the island. The sea
and the distant island looked comfortingly normal and beautiful in the
sunshine. Under so blue a sky it did not seem reasonable to worry about
anything. Events or schemes at the bottom of the sea seemed certainly
the last things to be likely to matter to anyone.

Terry had the _Esperance_ almost between the reefs before he tried the
new contrivance. If it worked, it should be possible to make a relief
map of the ocean bottom with every height and depth on the sea-bed
plotted with precision.

He started to operate the new instrument. First he traced the steep
descent from the flanks of the submarine mountain whose tip was Thrawn
Island. He traced them down to the abyss which was the Luzon Deep. Then
he began to trace the ocean bottom at its extreme depth, on what should
have been submarine plains at the foot of the submerged mountain. The
instrument began to give extraordinary readings. The bottom, in a
certain spot, read forty-five hundred fathoms down. But suddenly there
was a reading of twenty-five hundred. There was a huge obstruction,
twelve thousand feet above the bottom of the sea, more than twenty
thousand feet below the surface. The instrument scanned the area.
Something else was found eighteen hundred fathoms up. These were objects
of enormous size, floating, or perhaps swimming in the blackness. They
were not whales. Whales are air-breathers. They cannot stay too long in
deep waters, motionless between the top and the bottom of the sea.

The instrument picked up more and more such objects. Some were
twenty-five hundred fathoms from the bottom, and two thousand from the
surface. Some were twenty-two hundred up, and twenty-three hundred down.
There were eighteen hundred-fathom readings, and twenty-one, and
twenty-four, and nineteen. The readings were of objects bigger than
whales. They rose very slowly, and appeared to rest, then rose some
more, and rested....

Blank faces turned to Terry. He licked his lips and looked for Deirdre.
Then he said evenly, "We go into the lagoon. And if we come out
again--if!--we leave Deirdre ashore, unless these readings have been
cleared up. There are chances I'm not willing to take."

The _Esperance_ headed in. It was not possible for the new instrument to
tell what the large objects were. They could be monstrous living
creatures, perhaps squids, and one could only guess that their errand
was to deal with the surface-creatures--men--who speared fish and giant
squids and set off explosions in the Luzon Deep.

Or the rising objects could be, say, bolides which had dived into the
Deep from outer space and were now coming to the surface to make sure
that the natives of the earth did not again disturb the depths taken
over by beings from another planet.




_Nine_


The sun rose high in the sky as the _Esperance_ returned to the wharf.
Davis went ashore and held lengthy conversations with Manila by
short-wave radio. The biologists essayed to investigate the squid. _La
Rubia_ still attempted to catch fish. All efforts seemed to tend toward
frustration.

When Terry walked over to see his victim at close range, he found the
biologists balked by the mere huge size of the squid. There were
literally tens of tons of flesh to be handled. Squid have no backbone,
but a modified internal shell is important to biologists for study. The
biologists wanted it. The gills needed to be examined, and their
position under the mantle noted, and their filaments counted. The
nervous system of the huge creature must have its oddities. But the
actual preservation of the squid was out of the question. The mere
handling of so large an object was an engineering problem.

Terry consulted the frenziedly swearing Capitan Saavedra, who was ready
to weep with sheer rage as he contemplated torn nets, and fish he could
not capture. Squids were an article of commerce. Terry took the Capitan
to view this one. His crew would help the biologists get at the
scientifically important items, and for reward they would have the rest
of the giant--more than they could load upon _La Rubia_. This would make
their voyage profitable, and the Capitan would have the opportunity to
tell the most stupendous story of his capture and killing of the giant.
With the evidence he'd have, people might believe him.

Presently, the crewmen of _La Rubia_ clambered over the monster, huge
knives at work under the direction of the men from Manila. There was
bitter dispute with the tracking station cook, who objected to the use
of his refrigeration space to freeze biological material before it was
sent to Manila by helicopter.

In mid-afternoon the _Esperance_ left the lagoon again. The
sonar-depth-finder probed the depths delicately. The objects in mid-sea,
it appeared, had been rising steadily. Their previous position had
averaged twenty-five hundred fathoms deep. They were now less than two
thousand fathoms down, and there were many of them. Unfortunately, the
_Esperance_ was not a steady enough platform for the instrument. But a
fairly accurate calculation was made, and if the unidentified objects
continued their ascent at their present rate, they would surface not
long after sunrise. Then what?

Increasingly urgent queries came by short-wave, asking for Dr. Morton's
explanation of how he had computed the landing place and time of the
latest bolide. His accuracy was not disputed. But astronomers and
physicists wanted to be able to do it themselves. How had he done it?

Terry came upon him sitting gloomily before a cup of coffee in the
tracking station. Davis was there too.

"I wish I hadn't done it," Morton confided. "It's one of those things
that shouldn't happen. It's bad enough to have a giant squid to account
for. They tell me it's a new species, by the way. Never found or even
described before. One of the _Pelorus_ men tells me it's an immature
specimen, too. It's not full-grown! What will a grown-up one be like?"

"I have a hunch we'll find out when those submerged giants reach the
surface," said Davis unhappily.

Terry said, "The one we killed couldn't get out of the water. I wonder
if the adult forms can walk over the land!"

Davis stared. "Should we send Deirdre to safety on the _Esperance_?"

"Safety?" asked Terry. "On a boat? When a mass of bubbles from undersea
could provoke such a turmoil in the water that no ship could stay
afloat? That's how one ship disappeared. It might be the _Esperance's_
turn next. Who knows?" Then he added, "There's no limit to the size of a
swimming creature!"

A bald-headed member of the tracking station staff walked in. He
carried an object of clear plastic. It was a foot and a half long, about
six inches in diameter. There was an infinite complexity of metallic
parts enclosed in the plastic.

"I caught one of the fishermen making off with this," he said in a flat
voice. "It was fastened to one of the squid's shorter arms. The
fishermen didn't want to give it up. The skipper claimed it as
treasure-trove."

He put it down on the table. Davis, Terry and Morton looked at it. Then
Morton shrugged his shoulders, almost up to his ears.

"The intelligent being that made it," said Davis, "apparently came down
from the sky in a bolide. That's easier to believe than that a submarine
civilization of earthly origin lives down in the depths. But why would
anybody prefer the bottom of the sea to--anywhere else on earth? Where
would such a creature come from?"

Deirdre walked in and stood by the table, watching Terry's face. The
bald-headed man said, "I could believe some pretty strange things, but
you can't make me believe that a creature can develop intelligence
without plenty of oxygen. There's not much free oxygen at the bottom of
the sea."

"But there's something intelligent down there," said Davis doggedly. "If
it has to have free oxygen, you've only raised the question of where it
gets it. Maybe it brings it."

Deirdre shook her head. "Foam," she said.

The four men stared at her. Then Terry said sharply, "That's it! On the
_Esperance_ there's a picture of a huge mass of foam on the sea. A ship
dropped right out of sight right into it. Deirdre found the answer!
Something down below needs free oxygen. In quantity. Why not get it from
the water? What to do with the hydrogen that is left? Let it loose!
It'll come to the surface, make a foam-patch...."

Dr. Morton said with a sort of mirthless geniality, "I add a stroke of
pure genius! Davis just asked what would be the origin of a creature
which preferred the depths of the sea to any other place on earth.
What's to be found down there that's missing everywhere else? Cold? No.
Moisture? No. Just two things! Darkness and pressure! At the bottom of
the Luzon Deep the pressure is over seven tons to the square inch.
There's no light--I repeat, none--below three hundred fathoms. Down at
the sea-bottom it's black, black, black! Now, where in the universe
could there be creatures capable of riding down here in a bolide, and in
need of an environment like that?"

Terry shook his head. He remembered seeing a book on the solar planets,
in the after-cabin of the _Esperance_. He hadn't read it. The others on
the yacht must have.

"How about Jupiter?" asked Deirdre. "The gravity's four times the
earth's, and the atmosphere is thousands of miles thick. The pressure at
the surface should be tons to the square inch."

Morton nodded. With the same false geniality he added, "And there'll be
no light. Sunlight will never get through that muggy thick atmosphere!
So we consider ourselves to be rational beings and guess that the
bolides come from Jupiter! But I must admit that the last bolide was
headed inward toward the sun, and from the general direction of Jupiter.
So-o-o-o, do we warn the world that creatures from Jupiter are
descending in space ships and are settling down under water, at a depth
of forty-five hundred fathoms? Like hell we do!"

He got up and walked abruptly away.

"I ..." said the bald-headed man, shaking his head incredulously, "will
put this gadget away and go back to carve some more squid."

"I'll talk to Manila," said Davis drearily. "Something is coming up from
below. There shouldn't be any ships allowed to come this way until we
find out what's happening."

Deirdre smiled at Terry, now that they were alone.

"Have you anything very important to do just now?"

He shook his head.

"If the things that are coming up are--space ships, we can't fight them.
If they're anything else, they can't very well fight us. If we wanted to
attack something at the bottom of the sea we'd have to fumble at the
job. We wouldn't know where to begin. So maybe, if a submarine power
wants to attack at the surface of the sea, it may find it difficult,
too."

He frowned. Deirdre said, "Let's go look at the sea and think things
over!"

She very formally took his arm and they walked out. Presently, they
stood on the white coral beach on the outer shore, and talked. Terry's
mind came back, now and then, to how inadequate his previous guesses
about the impending menace had been. It seemed now that the menace must
be much worse than he had imagined. But there were many things he wanted
to say to Deirdre.

As they talked, they were disturbed. The helicopter, which had left
before noon loaded down with biological material for Manila, was
approaching again. It landed by the tracking station. Then they were
alone again.

When night fell, they were astonished at how quickly time had passed.
They went back to the station. The helicopter was on the ground. The
biologists had stopped their work, exhausted but very excited by their
discovery of a new species of squid, of which an immature specimen
measured eighty feet. It had offered extremely interesting phylogenic
material for the Cephalopoda in general. The photographs they'd taken
were invaluable, from a scientific viewpoint.

The crew of _La Rubia_ had returned to their boat. The _Esperance_ had
been out beyond the reef once more. The unidentified objects were still
rising. They had risen to less than a thousand fathoms from the surface,
well before sundown. At this same rate of rise, they should reach the
surface some time after midnight. What would happen after that?

"What will happen depends," said Terry, "on how accurate their
information about us is. It depends on their instruments, really. I
suspect their ideas about us are weird. I find I haven't any ideas about
them."

At dinner, Davis said worriedly, "I talked to Manila. The mine layer
that was in the Bay left harbor yesterday. The flattop picked it up by
radio and they're both going to come on here tomorrow. I had to talk
about the foam. They weren't impressed. The squid does impress them, but
the foam--no. I hate," he said indignantly, "to try to convince people
of things I couldn't possibly be convinced of myself!"

They talked leisurely. Somebody mentioned _La Rubia_. It had been more
or less expected that her skipper would turn up for drinks and
conversation again. But he hadn't. The conversation turned to the
plastic objects. They might or might not pick up sounds. It was not
likely they'd respond to light. Certainly, complete images would be
meaningless to creatures who had evolved in blackness and without a
sense of sight. They might respond to pressure-waves, such as are known
to be picked up by fish when something struggles in the water, even
though man-made instruments have not yet detected them. They might
furnish data of a sensory kind that is meaningless to humans, as
pictures would be to Jovians. _If_ there were such things....

"Why argue only for Jupiter?" asked Deirdre. "Venus is supposed to be
mostly ocean. There could be abyssal life there."

The crew-cuts joined in the argument, but tentatively, because there
were many experts present.

Midnight came. The open sea outside the reef showed nothing unusual. The
waves glittered palely at their tips. There were little flashings in the
water where an occasional surface fish darted. The stars shone. The moon
was not yet risen.

Two o'clock came. The _Esperance_ people were divided. Terry and Davis
were too apprehensive to sleep. Deirdre'd gone confidently to the yacht
to turn in. The crew-cuts slept peacefully, too. Davis said uneasily,
"I've got a feeling that the ... objects are at the surface, or very
close to it, but that they simply aren't showing themselves. I think
they're lying in ambush. The squid that was killed must have had trouble
getting into the lagoon. They probably won't try to get the big ones in.
They'll wait...."

Terry shook his head.

"We killed that little one--save the mark!--and its death was probably
reported in some fashion. So maybe they'll use the big ones on the
surface as bait for another kind of weapon. Foam, for example. We know
how a ship simply dropped out of sight, as if into a hole."

"I know!" said Davis drearily. "I told the flattop about that. But I
don't think they really believe it."

At two-thirty Davis and Terry went down to the yacht. They stood on the
deck. They kept watch by mere instinct. There was no activity anywhere.
Faint noises were coming from _La Rubia_. Maybe her crew was repacking
the hastily loaded masses of squid-flesh. The last-quarter moon rose at
long last, and shone upon the glassy-rippled water of the lagoon.
Star-images danced beside its reflection.

A little after three, quite abruptly, the Diesels of _La Rubia_ rumbled
and boomed. The dark silhouette of the ship headed across the lagoon
toward its opening. Terry swore.

"She lifted her anchor without making a noise," he said angrily. "Her
skipper wants to get to Manila with his catch before it spoils!
Damnation! I told him not to leave without warning. Anything could be
waiting outside!"

He raced for the shore and the outboard motorboat. Davis shouted down
the forecastle and pelted after him. Terry had the outboard in the water
by the time Davis arrived. He jumped in and pulled the starter. The
motor caught.

The outboard went rushing across the water. Its wake was a brilliant
bluish luminescence.

The booming of the Diesels grew louder. Capitan Saavedra thought he had
put over a fast one on _los americanos_, who had moved the fish from
where he regularly captured them in vast quantities and gathered them in
a lagoon where his nets tore. They had given him most of a monster
squid, true, but they had reserved certain parts for themselves. They
were undoubtedly the most valuable parts. So when labor officially
ceased at sundown, _La Rubia's_ skipper only pretended to accept the
idea. In the last hour his crew had quietly completed loading _La Rubia_
with squid. They'd been carefully silent. They'd lifted anchor without
noise. Now _La Rubia_ headed for the lagoon entrance, heavy in the water
but with precise information about what coral heads needed to be dodged.
She had on board a cargo history had no parallel for. Her skipper
expected to be rewarded with fame, as well as cash.

When the outboard motor rushed toward _La Rubia_, Capitan Saavedra
zestfully gave his engines full throttle. When the racketing, roaring
motorboat arrived beside his ship, and Terry shouted to him to stop, he
chuckled and drove on. In fact, he left _La Rubia's_ pilot-house to wave
cheerfully at the two men. They frantically ran close and shouted to him
above the rat-tat-tatting of their own motor and the rumble of his
Diesels.

_La Rubia_ reached the lagoon entrance with the smaller boat close at
her side, and Terry still shouting.

But Capitan Saavedra did not believe. Maybe he did not understand.
Certainly he did not obey. Ocean swells lifted and tossed the motorboat.
It became necessary to slow down, for safety. But _La Rubia_ went
grandly on, into the open sea.

"We can't force him to stop," said Davis in a despairing voice. "He
won't. I only hope we're wrong, and he gets through!"

The outboard stayed where it was, and swells tossed it haphazardly. _La
Rubia_ switched on her navigation lights. She drove zestfully to the
southward. She sailed on, dwindling in size, as the drone of her Diesels
diminished in volume.

Looking back, Terry saw the _Esperance_ approaching from the lagoon,
dark figures on her deck. Terry shouted, cries answered him, and the
_Esperance_ came to a stop as the motorboat drew alongside.

Terry and Davis scrambled to her deck while one of the crew-cuts led the
smaller boat astern and tethered it.

"We're safe enough here," Terry said bitterly, "and since you've come,
we can stay and watch if anything happens. If only she keeps on
going...."

But _La Rubia_ did not. Her lights showed that she had changed course.
She changed course again. Her masthead light began to waver from side to
side. She wallowed in such a way that it was clear she was neither on
course nor in motion any longer.

Nobody gave orders, but the _Esperance's_ engine roared. The action from
this point on became an automatic and quick response to an emergency.

The schooner-yacht plunged ahead at top speed. Terry switched on the
recorder and the ultrapowerful sound projector. Davis bent over the
searchlight. Two of the crew-cuts readied the bazookas.

Suddenly, a flare went off on _La Rubia's_ deck. Her stubby masts and
spars became startlingly bright. Screams came across the waves, even
above the growling of the surf and above the noise of the _Esperance's_
engine.

The flare shot through the air. It arched in a high parabola, bright in
the sky, and fell into the sea. Another flare was ignited.

The _Esperance's_ searchlight flicked on. A long pencil of light reached
across the waves as she raced on. More screamings were heard. Another
flare burned. It arched overside. The _Esperance_ plunged on,
shouldering aside the heavier waves of open water.

A half-mile. A quarter-mile. _La Rubia_ wallowed crazily, and more
shrieks came from her deck. Then the fishing boat seemed to swing.
Beyond her, a conical, glistening and utterly horrifying monster
emerged, a mere few yards from her rail. Enormous eyes glittered in the
searchlight rays. A monstrous tentacle with a row of innumerable
sucker-disks reached over the stern of _La Rubia_.

Another flare swept from the fishing boat's deck in the direction of the
giant squid. It fell upon wetted, shining flesh. The monster jerked, and
_La Rubia_ was shaken from stem to stern. Hurriedly, Terry pressed the
power-feed button, and the sound projector was on. Its effect was
instantaneous. The monster began to writhe convulsively. It was
gigantic. It was twice, three times the size of the squid captured in
the lagoon. Terry heard his own voice cry out, "Bazookas! Use 'em! Use
'em!"

Flaring rocket missiles sped toward the giant. Davis flung one of the
hand grenades he'd manufactured. The yacht plunged on toward the
clutched, half-sunk fishing boat. The hand grenade exploded against the
monster's flesh. Simultaneously, the bazooka-missiles hit their target
and flung living, incandescent flame deep into the creature's body.
Those flames would melt steel. They bored deeply into the squid, and
they were infinitely more damaging than bullets.

The creature leaped from the water, as chunks of its flesh exploded. It
was a mountainous horror risen from the sea. As it leaped, it had
squirted the inky substance which is the squid's ultimate weapon of
defense. But, unlike small squid, this beast of the depths squirted
phosphorescent ink.

The beast splashed back into the sea, and the wave of its descent swept
over the deck of _La Rubia_. The fishing boat nearly capsized. But the
monster had not escaped the anguish of its wounds. It fought the injured
spots as though an enemy still gnawed there. It was a struggling madness
in the sea.

The _Esperance_ swung to approach the half-sunken trawler, and Terry
kept the searchlight on the turmoil. The beast knew panic. It was
wounded, and the abyss is not a place where the weak or wounded can long
survive. Its fellows would be coming....

They did. Something enormous moved swiftly under the sea toward the
wounded monster. It could be seen by the phosphorescence its motion
created, as it approached the surface. There was a jar, a jolt. Some
part of it actually touched the _Esperance's_ keel. The huge monster
moved ahead, but a trailing tentacle flicked up to what it had touched a
moment before.

The ugly tentacle trailed over the yacht's rail. The rail shattered. The
forecastle hatch was wiped out. The bowsprit became mere debris which
dangled foolishly from the standing rigging.

The _Esperance_ bucked wildly at this fleeting contact. Nick fired a
bazooka-shell, but it missed. Holding fast, Davis flung a grenade. It
detonated uselessly. It was then that Deirdre screamed.

Terry froze for an instant. There had simply been no time for him to
think that Deirdre might be aboard. It was inexcusable, but nothing
could be done now.

Tony had been knocked overside by the shock of the contact with the
giant, and was swimming desperately trying to follow the yacht and climb
back on board. Terry flashed the searchlight about. He found Tony,
splashing. The _Esperance_ swung in her own length while Terry kept the
searchlight beam focused. More shrieks came from _La Rubia_. Davis threw
a rope and Tony caught it. They hauled him aboard, and the _Esperance_
turned again to pluck away the trawler's crewmen.

There were unbelievable splashings off to port. Terry flung the
lightbeam in that direction. It fell upon unimaginable conflict. The
monster that had passed under the yacht now battled the wounded squid.
They fought on the surface, horribly. A maze of intertwining tentacles
glistened in the light, and their revolting bodies appeared now and
again as the battered creature fought to protect itself, and the other
to devour. Other enormous squids came hurrying to the scene. They flung
themselves into the gruesome fight, tearing at the dying monster and at
each other. There were still others on the way....

The sea resounded with desperate mooing sounds.

The _Esperance_ bumped against _La Rubia_. Frantic, hysterically
frightened men clambered up from the deck of the sinking trawler to the
yacht. As soon as they were aboard they implored their rescuers to head
for land, immediately.

"Get 'em all off!" bellowed Terry, in command by simple virtue of having
clear ideas of what had to be done. "Get 'em all off!"

The stout skipper of _La Rubia_ jumped over the yacht's rail. Without
orders, the yacht's engine bellowed. The _Esperance_ turned toward the
shore, which now seemed very far away.

Something splashed to starboard. The sea glowed all around it. Terry
poured the pain-sound exactly in that direction. The monster went into
convulsions. The yacht swerved away to keep its distance. She raced on,
past the spot where the giant flailed its tentacles insanely about. It
mooed.

The _Esperance_ raced at full speed toward the island. About a mile
ahead, the surf roared and foamed on the coral reef almost awash.

Back at the scene of the battle of monsters, there was a sudden break in
the conflict. One of the wounded giants broke free. It may have been the
one the _Esperance_ had first attacked; perhaps it was another, which
might have been partly devoured while still fighting.

In any case, one of them broke loose and fled, with the hellish pack
after it. It is the instinct of squids, if injured, to try to find some
submarine cavern in which to hide. The monster dived, and the others
pursued it. There was no opening in the reef barrier--not underwater.
But there was an opening on the surface. The crippled beast had to find
a refuge, or be torn to bits. It may have been guided by instinct, or
perhaps the current flowing into or out of the lagoon furnished the
clue. In any case, the fleeing creature darted crazily into the channel
used by the _Esperance_ for passage. For a little way, it proceeded
underwater. Then it grounded itself. Hopelessly.

And the pursuing pack arrived.

The sight from the _Esperance's_ deck was straight out of the worst
possible nightmare. Glistening serpentine tentacles writhed and flailed
the seas. They tore the swells to froth. The pursuers had flung
themselves savagely upon the helpless one. The gap in the reef was
closed by the battling giants. They slavered. They gripped. They tore.
They rent each other....

Terry saw a tentacle as thick as a barrel which had been haggled half
through and dangled futilely as its stump still tried to fight.

And more giants came. Terry shouted, and the _Esperance_ turned. He
could see large patches of phosphorescence under the surface. And
suddenly, he noticed that a few of them had swerved toward the
_Esperance_. As they approached the sound-horn stung them. They went
into convulsive struggling, as the sound played upon them, and they
passed the _Esperance_ by.

Davis found Terry beside the sound-weapon's controls watching the sea
with desperate intensity.

"Listen," said Davis fiercely, "we're out at sea and we can't get back
into the lagoon! We'd better get away from here!"

"Across deep water?" demanded Terry. "That dangerous foam can come up
from deep water, but maybe not from shallow water. We've got to stay
close to the reef until the flattop comes and bombs these creatures--if
it will ever come!"

Davis made a helpless gesture. Terry said crisply, "Get the 'copter to
hang over the reef and report on the fighting there. Tell it to report
to the flattop. They may not believe us, but they may send a plane
anyway. And if the ships come, they'll have to believe about the foam!
Tell them to listen for it underwater. They've got sonar gear."

Davis stumbled away. Presently, the dark figure of Nick lowered himself
through what had been the forecastle hatch. Davis followed him.

Deirdre came over to Terry.

"Terry ..."

"I'm going to beat in the heads," said Terry, "of those idiots who came
after your father and me without throwing you on the wharf first!"

"They'd have wasted precious time," said Deirdre calmly. "I wouldn't
have let them. Do you think I want to be ashore when you ..."

There was the faintest of palings of the horizon to the east. Terry said
grimly, "I'm going to try to find a passage through the surf, to get you
ashore. I'm keeping the _Esperance_ in shallow water--inside the
hundred-fathom line--but I don't trust it. Certainly I don't trust a
ship to make you safer!"

"It's going to be daybreak soon," she protested. "Then...."

"Then we won't be able to see what goes on underwater," he told her.
"Those ... creatures down below are smart!"

There was a racketing, rumbling roar from the island. A light rose above
the tree-tops. Presently a parachute-flare lit up. Then there was
another, as if the men in the helicopter did not believe what they saw
the first time.

"Terry," said Deirdre shakily, "I'm ... glad we found each other, no
matter what happens...."

Davis came up from below.

"The flattop's only a few miles away. They're now proceeding at top
speed. The mine layer's following. They'll be here by sunrise."

       *       *       *       *       *

Far away to the east, some brightness entered into the paling of the
sky. A drab, colorless light spread over the sea. The ocean was a dark,
slate blue. Swells flattened abruptly about a quarter-mile away. Terry
aimed the sound-weapon and pressed the button. Something gigantic
started up, and the top of a huge squid's mantle pierced the surface.
The giant leaped convulsively, high above the water, save for trailing
tentacles. It was larger than a whale. It fell back into the sea with a
loud splash, and moved away quickly.

Color came into the sky. The sun's upper rim appeared. Flecks of gold
spread upon the sea.

Far, far away at the horizon a dark speck appeared. As the sun climbed
up over the edge of the world, the speck turned golden. There was a mist
of smoke above it. A plane took off from the ship. Another plane
followed.

Fighter planes flashed toward the island. One of them zoomed sharply,
like a bird astonished at something it has seen below. It whirled and
came back over that spot. There was the rasping whine of a machine gun.
Something like a giant snake reared up and fell back again. And now more
planes appeared.

Sunrise was suddenly complete. Terry stared out over the sea. And he
could not believe his eyes, accustomed as he was to the highly unlikely,
now. Giant squids were afloat at the surface. He saw one here, and
another there, and another, and another.... They were emerging by tens,
by scores.

"They've been sent up," said Terry very grimly, "by an entity that
didn't evolve on the earth. They're ... domesticated, in a way. They're
watchdogs for whatever arrives in bolides that fall in the Luzon Deep.
They are the reason for the shining circle of sea from which thousands
of tons of living fish were drawn down into the abyss. The
creatures--the ... _ellos_ who listen to what fish and fishermen
say--they keep these things as domestic animals. And they have to feed
them. Those mooings were the ... cries of these things waiting to be
fed. Try to imagine that, Deirdre! In the blackness of the pit, in the
abyss at the bottom of the sea...."

A tentacle broke surface. Terry swung the sound-beam. A mantle reared
above the waves. A bazooka-shell hit it. Something huge and stupid and
monstrous fought the impalpable thing that hurt it....

Davis approached.

"These," he said absurdly, "aren't the creatures who made the plastic
objects. Maybe we ought to try to open communication with their masters.
Why should we fight? If we prove we can defend ourselves...."

"I suspect," said Terry, "that all intelligent beings think the same
way, intelligently. If we landed on another planet, on some part of that
planet that the natives didn't use but we could, it wouldn't be sensible
for those natives to welcome us! Trade with us, perhaps. But let us
settle down, no!"

There was a bomb explosion out at sea. A plane had dropped a
hundred-pound bomb on a monster at the surface. The flattop was now
distinct. Golden, almost horizontal sunlight struck upon it. Off to the
west a plane dived steeply, something dropped from it, and the plane
levelled off. A three-hundred-foot fountain erupted from the surface.
Then there came absolute proof that intelligence lay behind all this. It
was not human intelligence, to be sure. Men are tool-using creatures
nowadays. They imagine robots for fighting, and nowadays they make them,
but many centuries ago men ceased to try to use animals as combatants in
war.

The creatures under the sea had not. They'd send up giant squids to do
battle with men, as men once sent elephants against the Macedonian army.
It was naive. But the generals, the tacticians, the strategists of the
Deep did not remain wedded to the one weapon. Already, they saw that
beasts could be fought by men. So their instruments of battle changed.
Doubtless, orders were given, and five miles under the sea
something--something men could not have duplicated--began the
transformation of seawater into gas, in quantities past imagining. Tiny,
tiny bubbles were produced by some unguessable engine, and rose toward
the surface, in a steady stream. At the bottom they were under a
pressure of tons to the square inch. But the pressure lessened as they
rose, and as they rose they swelled. A bubble which was pinhead-size at
the sea-bed grew to be the size of a basketball a half-mile up, and
would have been the size of a house a mile up, except that then it
separated into smaller ones. They rose and rose and expanded and
separated. Five miles up from their origin, at little more than
atmospheric pressure, they made a rising column of insubstantiality. At
the surface they became foam. But under the foam there was more foam,
and under that still more. A ship sailing from normal ocean water into
such airy stuff would drop like a stone into the miles-long cone of
semi-nothingness. Nothing solid could float there. Nothing substantial
could rest its weight upon such rushing thistledown.

And the first of the bubble-weapons appeared at the surface in the form
of a patch of foam. Its source--and hence the place of its
appearance--could be moved. It could be shifted under any ship, though
there would be a time-interval, always, before the foam at the surface
was exactly above the gas-generating engine below. It could be moved to
anticipate the movements of a ship. But there was always that time-lag.

The _Esperance_ headed back toward the heap of monsters at the break in
the reef. Other giant squids emerged and joined the pack. A plane came
over and bombed it. The _Esperance_ turned away. The mine layer from
Manila appeared at the horizon. The flattop made a sudden violent turn,
and more foam appeared upon the water. It curled and writhed and piled
up to be ten--twenty--thirty yards in height.

The flattop fired a shell into it. There was a gigantic flash and flame,
and for an instant there was no foam, but only peculiarly pock-marked
ocean surface, instantly covered by more foam which piled up as before.

"Gas," said Terry grimly. "Hydrogen. You guessed right, Deirdre!"

Now the flattop shot off plane after plane, as if they were projectiles.
They swung in the air and flew low to drop bombs in the now wabbling,
moving, sweeping patch of white stuff. It was a huge discoloration of
the ocean surface. It was almost in diameter as the flattop's length.
Now the carrier dodged it warily.

There were dull concussions everywhere. Giant squids writhed in
death-agonies. White foam-patches appeared here and there--but somehow
haphazardly--as if fumbling for the ships. One patch swept close to _La
Rubia_, and that small derelict seemed to tremble. And then the fishing
boat touched the very edge of the white stuff, and was engulfed in it.
She vanished instantly, as if she had fallen into a hole in the sea.
When the foam-patch passed on, the sea was empty.

The effect of the foam, actually, was that of a gigantic, slavering,
blind gullet straining to devour. It moved erratically over the surface.
Terry called to Deirdre, "Have Nick tell the flattop that the foam only
comes up from deep water. If they can get inside the hundred-fathom
curve they're safe! Maybe even five hundred. Maybe more. But the foam
only comes up from deep water!"

The mine layer came on from the horizon at topmost speed. Apparently,
they had received warning from the carrier, because the ship suddenly
began to zig-zag. The carrier itself adopted the unpredictable
change-of-course system which had been originally designed to frustrate
submarines lying in wait. Both ships adopted it just in time. A ravening
area of foam appeared directly before the mine layer's bow just as she
turned aside. The mine layer dumped a mine. Terry saw it go overboard.
But it would have five miles to sink before it hit bottom.

Terry called Davis and jerkily explained that the mines would have to be
armed when they went overboard--set so that they would explode when they
hit bottom. He explained that depth-bombs might be useful against
squids, but if they went off at a fixed depth they would be harmless
against the enemy which deployed the squids.

The carrier, in the middle of a ninety-degree zig-zag turn, found her
bow projecting into a foam-patch. The bow sank deep. The carrier's
propellers were out of the water as her bow pointed downward. Had the
foam stayed still for two seconds, the carrier would have slid into the
column of gigantic ascending bubbles and plunged to destruction. But the
foam swerved sidewise.

The carrier escaped, and was infinitely cautious after that. She made
short, swift, unpredictable dashes this way and that.... Her
anti-aircraft guns rumbled and rattled at things upon the surface.
Presently, her depth-finder discovered an underwater extension of the
island's mountain-foundation, and the ship took refuge where the water
was less than a hundred fathoms deep. There she lay, shooting off planes
and retrieving them, her guns flashing at whatever targets appeared.

Twice, as it happened, snaky, monstrous arms flung themselves up and
heaved at the flattop as if the giant squids hoped to overturn even an
aircraft carrier by their weight. But those arms were blasted to
nothingness. The only damage they did was that a twenty-foot section of
tentacle--writhing independently on the flight-deck--broke the
landing-gear of a returning plane which collided with it.

The mine layer ploughed across the sea. From time to time she heaved
something overboard. Nothing seemed to happen. But each mine was,
nevertheless, so adjusted that it could explode any time it touched
something underwater. They did not allow the usual time so that the mine
layer could get away. The mine layer had ample time, because the mines
had to go slowly spinning down five long miles to the bottom of the
Luzon Deep.

Twenty mines went down before the first one detonated. The concussion
was felt on the _Esperance_, twenty-seven thousand feet up and in
shallow water. Then another, and another, and another. The mine layer
continued to sow her destructive seed. Far behind her, a monstrous
spouting of gas and spume rose up hundreds of feet. There was another
concussion, and another....

The _Esperance_ quivered, and Terry said grimly to Deirdre, "We set off
five pounds of explosive down the Deep, and the bathyscaphe returned all
smashed. What will the creature do now? I wish we could get some mines
down to the bottom there!"

Davis came up, beaming--but shaking.

"The carrier's sending some planes down to drop eggs at the spot where
the fish were dragged down!" he said zestfully.

Gigantic, terrifying masses of gas leaped skyward where the gases
released by the exploding mines finally reached the surface. The mine
layer zig-zagged, and dropped a mine. She zig-zagged again, and dropped
another. Presently, she took refuge beside the carrier. The _Esperance_
drove over and came to a stop between the two armed vessels. Someone
shouted down by megaphone from the carrier's deck, "What happened to
you? What hit your bowsprit?"

Terry shouted back, "You shot those beasts. We've been wrestling with
'em!"

An enormous eruption of gas.... Then the underwater ear began to emit an
unprecedented sound. It was a rushing sound, but it was only vaguely
like the noise of whatever had come up from the depths last Tuesday
night. This was powerful beyond imagining.

"Something's coming up!" roared Terry. "Better alert for a real fight
now!"

Deirdre said with a little gasp, "The real creatures are coming up!
Terry! The ... things that come in the bolides...."

He said savagely, "They've been shaken up badly by the concussions
underwater. They resented five pounds of explosive! There's been four
hundred pounds in every mine! If they try to fight after what they've
taken down below...."

The rushing sound from underwater was a loud, throbbing hum which had no
relationship with the humming sound that drove fish. Two spoutings of
gas from mine-explosions shot up. There were more concussions in the
water.

Then something broke surface. It was huge, and looked like a rocket. It
leaped. No, it dashed upward, toward the sky. It flashed skyward,
accelerating as it rose. Something else broke the surface and headed for
the heavens. This one was globular.

There were dull concussions coming from far underwater, and more rockets
broke surface and shot skyward.

Anti-aircraft guns were fired. Shell-bursts came close, but not close
enough. Not less than twenty enormous rockets leaped out of the water
and shot up toward the sky. Some observers claimed there were more than
thirty. Down to southward, where the bathyscaphe had been crushed, the
planes that were dropping mines reported that four other objects broke
loose from the ocean and fled for empty space at speeds too great to be
estimated.

Terry looked suddenly astonished.

"But ... of course!" he told Deirdre. "When you need high pressure, of
course you've got a weakness. You can't take concussions! Anything
underwater is completely vulnerable to bombs! Whatever was down there
has found out that the natives--we aborigines--have a weapon they can't
face. Primitive stuff. Explosives! Chemical explosives! And creatures
that can travel between planets and undoubtedly have atomic power
and--who knows what else--can't fight back if we drop submarine mines on
them!"

A last object broke surface and hurtled skyward. Behind it, deep, deep
down, there was a titanic explosion.

"Ah!" said Terry. "That was a time-bomb! They've gone home for good!"

       *       *       *       *       *

A task force of a private yacht, a fishing boat, a satellite-tracking
station, an airplane carrier and a mine layer had driven off an invasion
of earth. But the public could not be told that the earth had been
invaded. The people who had been involved in this secret adventure had
to be satisfied with the realization that they had saved mankind.

After a jubilant dinner Terry and Deirdre sat in the veranda.

Davis came out. He blinked at the night.

"Deirdre? Terry?"

"Here," said Terry.

Davis joined them. They had drawn apart a little.

"Good news by short-wave," said Davis. "Those rockets were picked up by
radar. They divided into two groups. One headed sunward. The other
headed for deep space. My guess is Venus for one group and Jupiter for
the other. They couldn't have come from Mars. But they've gone home.
Both groups."

Terry paused, and then said wryly, "Two races! Some of the bolides were
bullet-shaped and some were globular. That figures. But two races
capable of space travel and both in our own solar system!"

Davis grimaced. "We've been talking about it. Our guess is that the
Venus race developed in deep water, and therefore at high pressure. And
anything that developed on the solid surface of Jupiter would also be
accustomed to extremely high pressure."

Terry nodded. He was not exactly absorbed in what Davis had to say. But
he said suddenly, "I make a guess. They didn't want to start a colony
here. The sea-bottom here is too cold to be comfortable for the beings
from Venus, and far too hot to suit those from Jupiter. But both needed
terrific pressure. In order to keep contact with each other, in order to
do business, they could have set up a trading post here. To meet and
trade. Neither one could take over the earth. When you think of it, we
couldn't take over Venus or Jupiter! Maybe that's the answer!"

"Eh?" said Davis.

"We won't have to fight as planets," said Terry, "when we have
space-ships like they do. We couldn't gain anything by fighting. All we
can gain by is trade. They'll be pleased. It must have been horribly
inconvenient to have to set up a trading post here on earth. There were
always the natives, you know. Lately, they've noticed that we've been
getting restless. We have been. I imagine that now they'll wait for us
to make space-ships and start up interplanetary trade."

Davis said, "Very true. There's going to be the devil of a mess, though.
Morton will still have to explain the accuracy of his prediction about
the bolides' landings. I suspect he'll be censured for assuming anything
as unlikely as the truth has turned out to be."

Terry did not answer. Deirdre was saying something, and he did not hear
at all.

"There are still loose ends," added Davis. "For instance, how do you
suppose they controlled those squids down below? What did they use for
eyesight? How the devil would Jovians and Venusians agree on a meeting
place in our oceans?"

Terry answered what Deirdre'd said. She smiled at him. They'd forgotten
that Davis was there.

1.B.  "Project Gutenberg" is a registered trademark.  It may only be

1.C.  The Project Gutenberg Literary Archive Foundation ("the Foundation"

individual work is in the public domain 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

keeping this work in the same format with its attached full Project
Gutenberg-tm License when you share it without charge with others.

Gutenberg-tm work.  The Foundation makes no representations concerning
the copyright status of any work in any country outside the United
States.

1.F.

1.F.1.  Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
public domain works in creating the Project Gutenberg-tm
collection.  Despite these efforts, Project Gutenberg-tm 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.

of Replacement or Refund" described in paragraph 1.F.3, the Project

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.

Project Gutenberg-tm work, and (c) any Defect you cause.


Section  2.  Information about the Mission of Project Gutenberg-tm

Project Gutenberg-tm 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-tm's
goals and ensuring that the Project Gutenberg-tm 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-tm and future generations.

Section 4.  Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg-tm depends upon and cannot survive without wide
spread 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.

Section 5.  General Information About Project Gutenberg-tm electronic
works.

Professor Michael S. Hart was the originator of the Project Gutenberg-tm
concept of a library of electronic works that could be freely shared
with anyone.  For forty years, he produced and distributed Project
Gutenberg-tm eBooks with only a loose network of volunteer support.

Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as Public Domain 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 Web site which has the main PG search facility:

     www.gutenberg.org

This Web site includes information about Project Gutenberg-tm,
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.
