viii POULTRY CULTURE 



ideas and suggestions as to the presentation of the subject in such 

 a way as to meet the requirements of formal instruction. 



To give credit, in the proper connection, to each of the many 

 whose experiences and opinions have contributed something to a 

 work which represents a life interest in poultry and more than a 

 score of years of intimate business and professional acquaintance 

 with poultry culture would be impossible. So it has seemed best to 

 make few direct references in the text, but to give in the appendix 

 a classified list of the literature of the subject. 



The illustrations not credited to others are by the author. 

 Although many of the photographs and drawings were made for 

 this book, the elaborate scheme of illustration adopted was practi- 

 cable only because I already had a large private collection of pho- 

 tographs from which to select, and because I had access to the 

 files of photographs which had been used in Farm- Poultry . Those 

 from the latter source the publishers have kindly allowed me to 

 use, with this general acknowledgment.
