96 UNIVERSITY OF ILLINOIS. as eliminating variations. Hybridism. Grading and its benefits. Breeding in line and inbreeding. Instinct and intelligence. The aim is to bring every known principle o± reproduction to the assistance of the breeder's art. Lectures and reference reading. Fall term, full study. Professor DAVENPORT. Required. Botany 1; first term Zoology 3, i. FERTILITY.—Mutual reactions between fertilizer, crop, and soil. Effect of fertilizer on amount, character, and composition of crop. Residues or the fate of fertilizers, as determined by examination of the soil and its drainage water; effect of particular crops upon fertility and upon each other, whether growing in succession or together. Nitrification and leguminous crops. Economic sources of the elements of fertility, and their tendency to accumulate in the soil or to disappear in the drainage water. The knowledge thus obtained is made the basis for a rational study of fertilizers and their use, of rotations and of specialties>of extensive and of intensive methods, that the residue of one crop may be saved by the succeding one and not washed away. Spring term, full study. Professor DAVENPORT. Required. Botany 1: Chemistry 1, 3a, 4. 5. STOCK FEEDING.—Functional activities of the animal body and the end products of their metabolism. Foods are conr sidered, first chemically, as affording the materials for these activities whether in construction of body tissues or of animal products, as meat, milk, etc.; second dynamically, as supplying the potential energy for these processes, and for labor, speed, etc. Preparation of foods, their palatableness, and digestibility. This knowledge is used as a basis for calculating how the feeding practices of any locality may be adjusted to the consumption of the crops most successfully grown in that region, that domestic animals may become and remain, essentially, consumers of coarse crops and by-products. Optional, alternating with Agriculture 6. Spring term, full study. Professor DAVENPORT. Required. Botany 2; Physics 2; Physiology 1; Zoology 3. 6. SOILS.—Further study of soil conditions and properties, physical, chemical, and physiological. Cumulative effect upon soils of certain fertilizers and crops. Critical study of drainage and of drainage waters as compared with fertilizers applied, herbage produced, and rain-water fallen. Influence of crops
