JAPANESE SEALSKINS DELIVERED TO THE UNITED STATES 



The North Pacific Sealing Convention of July 7, 1911, provides 

 that 10 per cent of the fur-seal skins taken annually upon Robben 

 Island or any other islands or shores of waters defined by the con- 

 vention subject to the jurisdiction of Japan shall be turned over to 

 the United States Government unless the number of seals frequenting 

 the Japanese islands falls below 6,500, enumerated by official count. 



The United States Government's share of fur-seal skins taken by 

 the Japanese Government in 1930 was 172. They were received by 

 the department's selling agents at St. Louis, Mo., in January, 1931. 



INTERNATIONAL FUR-TRADE EXHIBITION AT LEIPZIG 



A joint resolution of Congress, approved by the President on 

 March 21, 1930, provided for participation by the United States in 

 the International Fur-Trade Exhibition at Leipzig, Germany, from 

 May 31 to September 30, 1930. The Departments of Agriculture 

 and Commerce cooperated in the preparation of exhibit material, 

 that of the latter department having to do principally with the fur- 

 seal resources of the Pribilof Islands. The showing of the Bureau of 

 Biological Survey featured the constructive efforts of that organiza- 

 tion along the line of conserving the country's fur resoun^es. The 

 display of the United States was primarily educational in character. 



Among the items assembled by the Bureau of Fisheries were a group 

 of mounted fur seals, a number of dyed fur-seal skins in the standard 

 black and logwood-brown colors, blue-fox and white-fox pelts, 

 mounted blue foxes, and two coats made from Pribilof Islands seal- 

 skins. Illuminated transparencies and other pictures of the bureau's 

 fur-seal and foxing activities were shown. There was also an interest- 

 ing portrayal of what has been accomplished since 1911 hj inter- 

 national cooperation in saving and rebuilding the fur-seal herd of 

 Alaska. 



All matters in respect to the preparation and installation of the 

 entire exhibit were admirably handled by the Office of Exhibits, 

 Department of Agriculture. Edward M. Ball, of the bureau's staff, 

 was detailed to that organization and was at Leipzig throughout the 

 exhibition. 



COMPUTATION OF FUR SEALS, PRIBILOF ISLANDS, 1930 



By Harry J. Christoffers 



The large number of surplus bulls observed on hauling grounds, 

 the favorable ratio of idle to harem bulls, the increased number of 

 3-year-olds available for killing, and the large number of 2 and 3 year 

 olds observed after the cessation of commercial operations, when 

 considered as a whole, indicate that the seal herd of the Pribilof 

 Islands is in a very satisfactory condition. 



During the summer sealing season of 1929 there were killed at the 

 Pribilof Islands 38,079 3-year-old male seals. This was an increase
