Spanish and Russian America 99 Cook’s Fournals published in 1784-5 directed the atten- tion of Europe, the East Indies, and the United States to the great value of the fur-fisheries in the North Pacific Ocean. Cook’s men were in fact the first to carry furs to China where they were highly prized. The only trade in furs at this time was that conducted by Britain in Hudson Bay, and by Russia in the northern parts of her own empire. Then followed a rush of ships from the United States, the East Indies, Macao, Canton, England, Portugal and Ostend, to engage in the fur-trade between America and China. The Russians under Gregory Shellikof advanced as far eastward as Kodiak Island in 1787. These varied activities alarmed Spain whose claim to the exclusive navigation of the Pacific and the peaceful pos- session of the sea-board was being openly flouted. Accord- ingly the Princesa and the San Carlos, two armed vessels under Estevan José Martinez, were dispatched in 1788 to investigate the establishment of Russian posts in Prince William Sound, Alaska. “‘According to the report addressed to the Viceroy of Mexico by Martinez, the Russian establishments in America were four in number, all of them situated west of Prince William Sound, and their population including soldiers and hunters amounted to 400. They had not advanced eastward, but reported that the Empress of Russia was about to send out a strong force to occupy Nootka.” } A subsequent memorial addressed by Madrid to the Empress of Russia, naming Prince William Sound as the boundary between Russian and Spanish America, was the first admission on the part of Spain of the right of any other Power to occupy a part of America bordering on the Pacific. 1Greenhow, Robert, Memoir of the North-West Coast, p. 96.
