ers' short courses, movable schools, for special subject mat- 

 ter instruction to teachers, agricultural and home demon- 

 stration agents, and for any other courses or purpose

 the various phases of poultry production have been elabo- 

 rately illustrated. Under "Breeds and Varieties," for ex- 

 ample, photographs are shown of the more popular breeds 

 of each of the more important classes, so that the reader 

 may have a graphic and complete idea of the appearance 

 of the fowls, their class, and their economic usefulness. 

 In hke manner other phases of poultry keeping are illus- 

 trated and discussed.
