without shortening the time of, or crowding out, any other 

 subject. 



Many of the complex problems encountered in the 

 management of the farm are discussed here with a view to 

 simplifying them, so that any one may easily understand 

 the principles involved. It may even prove valuable to 

 farm managers, by enabling them to put into practice 

 some of the better methods of soil and live stock manage- 

 ment, and to see clearly the aspects of farming as a busi- 

 ness. 



The idea of preparing these lessons originated with Mr. 

 D. A. Wallace, editor of The Farmer, and we gratefully 

 acknowledge his suggestions. 



We have freely used many of the agricultural books 

 and bulletins in the library at the Minnesota Agricultural 

 College, and have obtained much valuable information 

 therefrom. 



Nearly all photographs used were made by Mr. H. D. 

 Ayer, and the drawings were made by Mr. C. H. Welch 

 and Mr. G. F. Krogh. 



As it is difficult to keep changing the prices of farm 

 produce and labor as given in the problems, to keep in 

 harmony with market fluctuations, teachers may insert 

 market prices when assigning the lessons.
