40 REPORT OF THE COMMISSIONER OF FISHERIES. 



The general exhibit was designed to show the scope and functions 

 of the Bureau as comprehensively as possible, and was as complete as 

 space would allow. Artificial propagation was illustrated by examples 

 or models of apparatus and appliances used in collecting and hatching 

 eggs and distributing fishes, and throughout the exposition there were 

 demonstrations of actual hatching on a scale of considerable magni- 

 tude, many millions of eggs being utilized. This was supplemented 

 by mutascope pictures of fish-cultural methods as applied to different 

 species, as well as photographs and drawings, together with charts 

 showing some of the practical results. A model of the special railwa}' 

 cars used in transporting live fishes was shown, and on a railway siding 

 near the building one of the cars employed in bringing stock for the 

 aquarium was open for inspection when in the grounds. 



It is not easily possible to show the work of the division of scientific 

 inquiry with any degree of completeness, but in the space allotted to 

 this branch were exhibited the appliances used for collecting speci- 

 mens, such as trawls, dredges, tangles, seines, and surface, interme- 

 diate, and deep-sea tow nets, etc., the appliances for physical research, 

 and models of vessels maintained for ocean investigation. Experi- 

 ments in oyster culture and sponge culture were illustrated, and a fine 

 working model of the apparatus used by the Rhode Island fish com- 

 mission in rearing lobsters was in operation. There were collections 

 showing the anatomy, growth, variations, and distribution of lobsters, 

 oysters, clams, and other crustaceans and mollusks, and a series of 

 enlarged models of trout eggs in different stages of development. 

 Studies in fish pathology were illustrated by a display of cultures of 

 bacteria and by a series of colored drawings of fishes showing the 

 gross appearances of special diseases. 



Products of the fisheries were shown by a small but comprehensive 

 display of fish prepared for food in various ways, collections of oils, 

 fertilizers, glues, isinglass, leathers made from skins of water animals, 

 furs, whalebone, walrus ivory, tortoise shells, pearl shells, etc.; and 

 the methods of capture by models of types of modern fishing vessels 

 used on various parts of the coast, and by specimens of nets, traps, 

 seines, trawls, hand lines, dredges, tongs, and other appliances. There 

 was also a very complete series of colored photographs and mutascope 

 views of fishing scenes. 



At the close of the exposition most of the material was shipped to 

 Portland, Oreg., as part of the exhibit of the Bureau at the Lewis and 

 Clark Centennial exposition, which opened May 1, 1905. 



NORTH CAROLINA SHAD FISHERY AND LEGISLATION. 



For several years the very valuable shad fishery of North Carolina 

 has been declining, and in consequence of the scarcity of ripe fish the 

 Bureau's shad hatching operations in that State have been much inter-
