PROGRESS IN BIOLOGICAL INQUIRIES, 1934 335 



trout investigations. The Wisconsin Natural History and Geologic 

 Survey has coopoiated with the Bureau in many ways. Yale Uni- 

 versity, Cornell University, the University of Washington, and the 

 Oregon State Agricuhural College have likewise provided quarters 

 or other facilities for investigative work. 



The value of this type of cooperation cannot be overestimated. The 

 Bureau's investigators receive, in addition to actual laboratory and 

 office quarters, the use of university libraries, advice, and assistance 

 from the university faculties, and many other courtesies which stimu- 

 late a comnumity of interest in technical problems of the fisheries. 

 The universities thus c(mtribute to research of practical value and 

 application to their ow^n communities; and their graduate students 

 receive stimulation and advice in research problems similar to those 

 of the Bureau and frequently part-time or temporary employment 

 in Bureau projects, all of which contributes to the progress of aquatic 

 biology in the United States. 



Grateful acknowledgment of these various forms of cooperation is 

 made as a rule in the section dealing with fishery investigations in 

 the various localities.
