The bureau of animal industry, bureau of biological survey, 

 and bureau of entomology are especially interested in animals. 



Four series of publications are distributed by the Department 

 of Agriculture: (i) popular and semi- technical bulletins dealing 

 with the results of investigations; (2) the Journal of Agricul- 

 tural Research for scientific papers, and the Experimental Sta- 

 tion Record; (3) Farmers' Bulletins containing " specific direc- 

 tions for doing things "; and (4) annual reports, etc. Besides 

 this the newspapers throughout the country are supplied with 

 " brief popular statements of facts," and news letters are 

 weekly sent out to more than 50,000 crop correspondents and 

 farmers. Literature on almost any subject dealing with the 

 rearing of animals and plants and the control of pests can be 

 obtained free of charge by writing to the Secretary of Agriculture, 

 Washington, D. C.
