sites. He compiled the tables of feeds in the appendix and 

 prepared the index as well as read proof on the entire 

 manuscript. 



Mr. E. N. Wentworth, Professor of Animal Breeding, 

 Kansas State Agricultural College, read the manuscript of 

 the chapter on Breeding, and suggested several changes that 

 add greatly to its value. 



Messrs. W. A. Henry and F. B. Morrison of the University 

 of Wisconsin, very kindly gave permission for the use of the 

 analyses found in Table XLVII in the appendix, which were 

 taken from their volume, Feeds and Feeding. 



I also desire to acknowledge my indebtedness i to Mr. 

 James E. Rice, Professor of Poultry Husbandry, Cornell 

 University. It was my good fortune to secure my first college 

 training in this subject under his direction. The principles 

 that I learned from him are to be found throughout this book.
