MUCH experience has taught that if agriculture is made 

 the object of brain work, as well as of manual labor, 

 better farms, and better farmers, will be produced. 

 This book, therefore, is intended to present in a concise, prac- 

 tical manner for pupils in elementary schools, those funda- 

 mental principles upon which successful agriculture depends. 

 ^[ The farm is treated as the center of interest, and its in- 

 dustries, economies, and science are discussed at some length. 

 The book has been prepared with special reference both to 

 simplicity and to scientific accuracy, and is based on the 

 observation of the every-day facts of rural life, and on a system 

 of simple experiments well within the resources of any school. 

 *[[ The pupil is taught the reasons for the more important agri- 

 cultural operations, and the explanations of the phenomena 

 which accompany them. The soil and vegetation are first 

 taken up, including such important topics as the rotation of 

 crops, parasites of plants, seed testing, animals that destroy in- 

 sects, and the improvement of plants. Then follow chapters on 

 dairying, live stock, poultry, bee-keeping, and the improve- 

 ment of home and school yards. 



*J[ At the end of each chapter is a summary of what has 

 been presented, furnishing in concise form definite state- 

 ments for the pupil to learn, and supplying to the teacher 

 a basis for drill work. An extensive appendix contains, among 

 other useful information, fodder tables, a table of fertilizing 

 constituents in feeding stuffs, and sections on milk testing, 

 silage, contents of fields and lots, and quantities of seed 

 required to the acre.
