PUBLICATIONS AND LIBRARY. 
The demand for the publications of the Bureau is increasing yearly, 
and the supply of many 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.
