It has been the experience of the author that the teaching of feeding taxes the ingenuity of the agricultural instructor more than most other agricultural topics. The mere statement of principles without application or proof offers little of permanent value to the pupil. On the other hand, an attempt to pursue all, or even a small part, of the mass of data necessary to prove even a single principle, leaves the student groggy and confused. Neither is there time allowed in most courses for such procedure.
