FOREWORD 



It is to meet the need of vocational agricultural secondary 

 schools that this effort has been put forth to arrange in 

 sequence those facts that the student needs in elementary poul- 

 try work. It is intended that these chapters shall be given in the 

 classroom at the time of the year when suitable material will 

 be available for the corresponding laboratory practice periods, 

 though each chapter, being complete within itself, allows the 

 assignment of the chapters in any order the teacher may choose. 

 Working diagrams and photographs are provided for these 

 practice periods, in order that the work of the teacher may be 

 lightened. 



Suggestions are made for library references for the labora- 

 tory periods which should accompany each lesson, and out- 

 line suggestions are given for two major projects, with two 

 minor projects that dovetail together. There is also included 

 a school demonstration to show that crossbreeding for two 

 generations means scrubs. In addition to the twenty-two les-. 

 sons and the twelve laboratory exercises accompanying them, 

 thirty-two additional laboratory exercises are suggested, together 

 with fourteen skills. 



Under the above arrangement, it is believed that a complete 

 course, so far as it goes, can be given in twenty-five periods only 

 and that, by additional laboratory exercises and skills, these 

 hours can be stretched to fifty or even seventy-five or a hundred 

 periods, should it be the desire of the teacher to do so. Many 

 of the laboratory exercises will extend over at least two periods 

 if the work is completed satisfactorily: for example, the con- 

 struction of the combination sitting and brooding coop. 



I wish to thank the following persons for valuable sugges-
