vi PREFACE 



The authors take pleasure in acknowledging their in- 

 debtedness to the following persons for the valuable aid 

 which they have given in the preparation of this book 



Prof. J. E. Dougherty 



Mrs. Elia Fowler * 



James Glasgow 



John C. Kriner 



Charles McClave 



Courtland H. Smith 



Further and more particular acknowledgment is due 

 Andrew S. Weiant who was formerly the turkey and 

 guinea specialist of the Bureau of Animal Industry, 

 United States Department of Agriculture, and upon 

 whose work and studies, both in the form of his pub- 

 lished Farmers' Bulletins and otherwise, the authors have 

 drawn heavily. Special acknowledgment is likewise due 

 J. W. Kinghorne, Junior Poultryman, Bureau of Animal 

 Industry, United States Department of Agriculture, for 

 the thorough and painstaking manner in which he has 

 indexed the book. 



For the period of the past ten years the authors have 

 been privileged to work together in the closest relationship 

 for the interests of the poultry industry of the United 

 States. It is to them a matter of deep pride that during 

 this time their first thought has always been to render 

 a service to the poultrymen and women of their country. 

 And it is with this same idea of service that they offer 

 the present book to the poultry public.
