revision and their distribution after they are printed. It also maintains an 

 information service, by means of which the results of investigations are made 

 known to the people of the State through the agricultural and rural press. 



The regular publications issued by the College and the Station cover 

 a useful but somewhat limited field. To place even the popular ones in 

 all the farm homes of the State, even if it could be done, would entail 

 an immense expense. Yet the College feels that it should do everything 

 possible to help all farmers apply what the scientists know and what the 

 best farmers practice. With this object in view, the regular publications 

 of the College have been made easier to understand and to apply. The 

 scientific bulletin for the scientist is wholly differentiated from the popular 

 one for the general reader. The publications of the latter group have 

 been made more attractive, brief, simple, and clear. 



The agricultural and home economics facts issued during the past year 

 through the cooperation of the press of the State comprised 450 different 

 items, with an aggregate circulation, as shown by press clippings, of 

 42,959,410, or about 8,000,000 more than the circulation in the year 

 ending June 30, 1917, which was 34,331,422. Tn connection with agricul- 

 tural war work these items had to do mainly with food growing and food 

 saving, with special campaigns for increased production of staples and of 

 home garden products and for increased use of dairy products, potatoes, 

 and perishable foods. 



The publications issued by the College during the year ending June 

 30, 19 1 8, are as follows:
