"A practical course in botany" by Eliza Frances Andrews is a scientific textbook written in the early 20th century. It presents a hands-on introduction to plant biology with strong emphasis on seeds, germination, plant structures, physiology, ecology, and their practical ties to agriculture, economics, and sanitation. Aimed at teachers and students, it favors simple, accessible experiments and field work over elaborate apparatus, and it advocates conserving native wildflowers while using cultivated specimens
for study. The opening of this textbook sets a practical, experiment-driven tone: the preface explains the goal of meeting entrance requirements while keeping the science useful, accurate, and low-jargon; it stresses using common materials, grouping experiments to support the text, and protecting wild flora. Chapter I centers on seeds—their economic importance, why plants store food for seedlings, and the main food classes (sugars, starches, oils, proteins)—then introduces cells, digestion by diastase, and straightforward tests for food substances. It examines seed water relations and respiration through simple trials, and guides dissections of corn, beans, castor bean, squash, and pine to compare cotyledons, endosperm, and embryo structure. The section closes with seed dispersal by wind, water, animals, explosive pods, and self-planting devices, linking form to function with quick demonstrations and field prompts. At the start of Chapter II, students detect oxidation and carbon dioxide release during germination, test conditions for sprouting (moisture, air, depth, temperature, heat tolerance, seed age and quality), and begin observing early seedling development in monocots such as corn.
