“ The Alaska Commercial Company, of San Francisco, leased the best islands for seal and otter fishing. From the United States the company leased the Pribilof Islands in Bering Sea, a great fur-seal metropolis with a population of nearly four millions. They had armed native gamekeepers and the help of an American gunboat. From Russia the company leased Bering and Copper Islands off Kamchatka,151 and Cape Patience on Saghalian with its outlier Robber Island. There also they had native gamekeepers, a patrol ship, and the help of Russian troops and gunboats. ”
