172 U. S. BUREAU OF FISHERIES 
in connection with tests on the feeding of fish oils and fish meals to 
poultry. Our Seattle technological laboratory staff also continued its 
close cooperative relation with members of the faculty and staff of the 
University of Washington, Seattle, Wash., as in past years. 
The University of Maryland and the Maryland State Agricultural 
Experiment Station, College Park Md., continued their excellent 
cooperative relations with our College Park technological laboratory 
staff. Additional free space for the Bureau’s laboratories was pro- 
vided by the University of Maryland for the expanded technological 
work of the Bureau at that place. For example the use of another 
room was donated to the Division for the establishment of a new 
bacteriological laboratory in the Horticultural Building of the Uni- 
versity. The various departments of animal husbandry of the 
Maryland State Agricultural Experiment Station continued their 
cooperation in the conduct of feeding tests of fishery byproducts 
in the rations of farm animals. The members of the staffs of these 
two institutions who have worked closely with our College Park 
technological staff are Dr. L. B. Broughton, Head of the Chemistry 
Department; Dr. W. C. Supplee and Mr. L. E. Bopst of the Chemistry 
Department; Dr. L. H. James, Head of the Department of Bac- 
teriology; and Prof. M. H. Berry of the Dairy Department. These 
various cooperative studies are described in greater detail elsewhere 
in this report. 
As discussed in the 1937 report, the Bureau’s technologists continued 
their cooperation with the Virginia State Division of Markets in 
extending and improving State marketing grades for fishery products 
sold in that State. 
The Bureau’s economists and marketing specialists are working 
in close cooperation with the Division of Markets of the Virginia State 
Department of Agriculture and Immigration in connection with the 
survey of retail fish markets which is discussed elsewhere in this 
report. The Division of Markets furnished the services of a man who 
surveyed the retail fish markets in Harrisonburg, Staunton, Lexington, 
Roanoke, Lynchburg, and Charlottesville. These markets could not 
otherwise have been covered. 
In the conduct of its statistical research work the Bureau obtains 
unusual cooperation from various States. The statistical surveys of 
the fisheries in the States bordering on the Great Lakes, in the Pacific 
Coast States, and in New York, Maryland, and Virginia have been 
greatly facilitated by the cooperation obtained from the fishery 
agencies in these States. With this aid it is now necessary for the 
Bureau to conduct only partial surveys in these States to supplement 
the data available from the fishery agencies. A comprehensive sys- 
tem for the collection of fishery statistics in the State of Maine is now 
being developed by the State of Maine in cooperation with members 
of the Bureau’s staff. 
In addition, in nearly every other State where commercial fishing is 
prosecuted, some type of cooperation in its statistical work is rendered 
the Bureau by the State fishery agencies or other organizations. This 
makes it possible for the Bureau to make statistical surveys of a 
greater portion of our fishery industries than otherwise would be 
possible.
