PUBLICATIONS AND LIBKARY. 



The demand for the publications of the Bureau is increasing yearly, 

 and the supply of raan}^ of the bound volumes and pamphlets has 

 become exhausted. Much of the matter printed by the Bureau is of 

 permanent interest, and requests for special articles continue for 

 years. The second edition of the very popular and useful "'Manual 

 of Fish Culture'' has been entirely distributed, and a new edition, 

 with revisions, is much needed. There have been sent out to regular 

 recipients and on the application of Congressmen and others 1,797 

 bound volumes and 20,192 pamphlets.
