4 U. 8S. BUREAU OF FISHERIES 
has been provided by the University of Maryland, and both the 
University and the Maryland State Agricultural Experiment Station 
are conducting in their various laboratories and departments of animal 
husbandry cooperative studies of the feeding value of fishery by- 
products. The members of the staffs of these two institutions engaged 
in these cooperative investigations are Dr. L. B. Broughton, Dr. W. 
C. Supplee, L. E. Bopst, and M. H. Berry. 
Prof. Samuel B. Schofield, head of the chemistry department, 
Western Maryland College, Westminster, Md., conducted and assisted 
in the supervision of a cooperative study of the chemistry of fish pro- 
tein in the college laboratories with the aid of student assistants. 
There was continued in Massachusetts, during the past year, by our 
fish cookery and home economics worker in cooperation with the 
Massachusetts State Department of Agriculture, a project covering 
lectures and practical demonstrations in fish cookery at various 
schools, women’s clubs, and other gatherings. This educational 
program was conducted by Miss Agnes I. Webster of our staff and 
R. H. Sullivan, of the State Department of Conservation. 
These cooperative investigations in the above mentioned State 
universities and institutions are described in greater detail elsewhere 
in this report. 
In the conduct of its statistical research work, the Bureau also 
obtains unusual cooperation from various States. The surveys of the 
fisheries in the various States bordering on the Great Lakes, in the 
Pacific Coast States, and in Maryland and Virginia, have been greatly 
facilitated by special cooperation obtained from the State fishery 
agencies in these States. With this aid, itis now only necessary for the 
Bureau to conduct partial surveys in these States to supplement the 
data available from the fishery agencies. 
In addition, in nearly every other State where commercial fishing 
is prosecuted, some type of cooperation on its statistical work is 
rendered the Bureau by the State fishery or other agencies. This 
makes it possible for the Bureau to make statistical surveys of a 
greater portion of our fishery industries than otherwise would be 
possible. 
EXHIBITS AT EXPOSITIONS 
During 1936 the Division, under the direction of the writer, super- 
vised the construction and maintenance of the Bureau’s exhibits at 
the Texas Centennial Central Exposition at Dallas, Tex., and the 
Great Lakes Exposition at Cleveland, Ohio, and the maintenance and 
dismantling of the exhibit at the California Pacific International 
Exposition at San Diego, Calif. 
TEXAS CENTENNIAL CENTRAL EXPOSITION 
The main feature of the exhibit at the exposition in Dallas consisted 
of a painted mountain and lake background, incorporating a miniature 
falls in the distance, over which water ran into a pool stocked with 
bass, crappie, and other warm-water fishes. The foreground was built 
up with rocks, trees, bushes, and other vegetation. A mechanically- 
operated model of an angler fishing in the pool near a miniature 
electrically-operated campfire gave a realistic appearance to the dis- 
play. The entire exhibit was lighted to give the effect of sunrise to 
sunset at regular intervals, and during the dark period there was an 
illusion of clouds floating through the sky.
