36. Agricultural Publications. Over 9,000,000 copies of 

 farmers' bulletins are distributed annually by the United 

 States Department of 

 Agriculture. Any per- 

 son in our country can 

 be enrolled on applica- 

 tion, and can receive the 

 free monthly list of avail- 

 able Department pub- 

 lications. These pub- 

 lications are sent, for the 

 most part, free of charge, 

 on request. 



Interesting and in- 

 structive matter is also mailed free by the State Colleges 

 and Experiment Stations. Helpful books relating to 

 farming, country life periodicals, and carefully prepared 

 matter sent to local newspapers exert great influence 

 in rural sections. The state and local associations of 

 stockmen, horticulturists, and grain growers distribute 

 their proceedings widely. The printed page attrac- 

 tive, readable, and reliable, as it has now come to be 

 is awakening a better life in the country, and its influence 

 for good cannot be measured.
