FISHERY INDUSTRIES OF THE UNITED STATES, 1938 171 
mutual work may be furthered or its ends made more effective and 
valuable. 
Thus, the technologists of this Division gave courses in canning 
fishery products to State Extension Service workers at the request of 
and with the cooperation of the Extension Service of the United 
States Department of Agriculture. Demonstrations and practical 
instruction on other related subjects, pertaining to the preservation 
of fishery products and a better utilization of the excellent food value 
of fish, were given to State Extension Service workers through and 
with the cooperation of the Extension Service of the United States 
Department of Agriculture. In some eases, students or State Exten- 
sion Service workers were detailed to the Bureau’s laboratories in 
Washington, D.C., for instruction, and in other cases one of our tech- 
nologists visited some of the States for this purpose. 
Cooperation was also given by members of our technological staff 
to chemists and bacteriologists of the Food and Drug Administra- 
tion, United States Department of Agriculture, at various times in 
connection with the development and application of tests or methods 
of determining the quality and constituents of various fishery products. 
On several occasions members of the Division’s economic and 
marketing staff cooperated with the Department of Labor in holding 
conferences with fishermen’s unions and associations to settle disputes. 
The Department of Labor, through its Employment Service, also 
gave considerable aid to the Division in selecting personnel for the 
conduct of the Division’s survey of retail fish markets. 
The Division also has worked with various Federal agencies in 
obtaining statistical data on our fisheries. In a cooperative arrange- 
ment, the Bureau of Agricultural Economics, Department of Agri- 
culture, furnished statistics on the volume of cold-storage holdings of 
fish and quantities frozen, and the health authorities in Washington, 
D.C., assisted in obtaining data on the volume of fish handled at the 
Municipal Fish Wharf and Market in this city. Cooperation was 
accorded the Bureau of the Census in obtaining for that Bureau figures 
on the volume of the quarterly production and holdings of fish oils 
in the United States. 
In addition to the specifically enumerated instances of cooperation 
with other Federal agencies cited above, which are on a continuing 
basis or were of a more detailed nature, it should be stated that a very 
close relationship exists between this Division and many of those 
Federal agencies whose duties require an interest in fish in particular, 
foodstuffs or feedstuffs in general, or in various marine activities. 
The staff of the Division is in almost daily contact with some one or 
more of these Federal agencies in the exchange of information of 
inestimable value to the scientific work of the Federal establishment. 
COOPERATION WITH STATE AGENCIES 
The Division has continued to encourage cooperative relations 
with State institutions and agencies in the conduct of researches and 
investigations of mutual interest. This policy has resulted in expanded 
programs and decreased costs. During 1938 the following coopera- 
tive investigations with various States were conducted: 
At Washington State College, Pullman, Wash.., the Seattle tech- 
nological laboratory staff of this Division worked with Dr. J. S. Carver
