viii PREFACE 



All of the practices recommended are planned and described 

 especially for the small flock. In many cases, suggestions 

 or references have been made covering the application of 

 these same principles to large flock management. An effort 

 has been made to keep the material general in nature so 

 that it will apply to all sections of the United States and 

 Canada. Following each chapter laboratory exercises have 

 been introduced. If these are followed out in the home or 

 school flock or through trips of inspection to nearby poultry 

 flocks as recommended, they will help materially to fix in 

 mind the lessons of the text and will enthuse interest in the 

 course. Thought questions have been placed at the end of 

 each chapter to aid in reviewing the text material. They 

 also emphasize and call special attention to the leading and 

 more important points covered. A list of reference bulletins 

 have been placed at the end of most chapters. These publi- 

 cations are known as Farmers' Bulletins, and can be secured 

 by addressing the Secretary of Agriculture, Washington, 

 D. C. The school library should contain a complete list of 

 these bulletins, and the pupil should be induced to secure 

 them for his home library. The study of these references in 

 connection with the text will aid in giving a much broader 

 and more detailed conception of many of the problems. 



Special acknowledgment is due a number of persons for 

 help in the preparation of parts of the text. Mrs. Harry R. 

 Lewis has materially aided in the completion of the work 

 by correcting manuscript and proof. And to others, in- 

 cluding poultrymen, teachers and farmers, whose names do 

 not appear, the author wishes to express his appreciation 

 and indebtedness for encouragement and help given. Pho- 

 tographs have been secured from a number of poultrymen 

 and farmers and from a number of Experiment Stations; 

 credit is given where they appear. All photographs not 

 especially credited have been taken by the author. L. P. 

 Graham is here given credit for a number of photographs
