 REFERENCES 



The following list of references will supplement the various phases of subject 

 matter presented in the text. As many of them as possible should be in the 

 school library for the use of teacher and pupils. 



The pamphlets may be obtained, with few exceptions, free of cost. Requests 

 for publications of the United States Department of Agriculture should be 

 addressed to the Secretary of Agriculture, Washington, D.C. It is not neces- 

 sary to write the title in the request but it is important to give the number of 

 the bulletin or circular and the class to which it belongs, for example, Farmers' 

 Bulletin, No. 77; Yearbook Separate, No. 637; Department Bulletin, No. 78. 



Bulletins and circulars published by various State Agricultural Experiment 

 Stations and State Departments of Agriculture may usually be obtained with- 

 out expense. In the list of these references the address of the station or state 

 department of each is given.
