DIVISION OF PUBLICATIONS. 



The results of the experiments, investigations, and activities of 

 the department are made available for the information and guidance 

 of the people by means of its publications. 



By the most careful economy it was possible to issue 24,900,557 

 copies of 1,4G2 new pamphlets, containing 32,842 printed pages and 

 3,518 illustrations, and 9,778,000 copies of 648 reprinted documents, 

 containing 23,179 pages and 3,977 illustrations. Therefore the total 

 publications handled in this office amounted to 2,110 separate pam- 

 phlets, containing 56,021 pages and 7,499 illustrations, and aggre- 

 gating 34,678,557 copies. Of these 20,998,557 were miscellaneous 

 publications, 10,409,000 were Farmers' Bulletins, and 3,271,000 were 

 lists of available Farmers' Bulletins. That so many new publications 

 were issued and so great a number distributed is due to the economical 

 and efficient supervision of the printing fund by the Division of 

 Publications. 



NO PUBLICATIONS WASTED. 



The fact of greatest interest in connection with this large volume 

 of publications is that they were all distributed to people who asked 

 for them, and that many more could have been sent out if we had 

 Ijeen able to fully supply the demand, which came from every section 

 of the country. No one who appli(Ml has failed to receive at least 

 some of the publications he wanted if they were available. It has been 

 tlie policy to supply some publications to every applicant rather than 

 a large number to a few jiersons. and with the exercise of discretion 

 in the distribution of the publications none has been wasted.
