The first Americans since 1814 who crossed to the west side of the Rocky Mountains was (at least to our knowledge) Mr. Jedidiah Smith with five trappers, who, having met some of the Hudson's Bay Company on the headwaters of Snake River came with them to the Hudson's Bay post at the Flat Heads, where they passed the winter. In 1825 he returned to join his people, and in 1826 he brought a large party of his countrymen to hunt in the Snake country, where they have been ever since. In 1826 and up to 1828, there were constantly five or six hundred. But now, that beaver are scarce, there are only about fifty. In 1827, Mr. Smith pushed his trapping parties to the Bay of San Francisco, in California, and, in endeavoring to make his way here from California in 1828, fifteen of his men were murdered by the Umpqua Indians when he with only three of his men reached Vancouver from whence, spring 1829, he proceeded to join his countrymen in the Snake country. The first American vessel that entered the Columbia River to trade since 1814 was the Oahee, Captain Dominus, in February, 1829. The Convoy, Captain Thompson, came a while after. These two vessels belonged to the same party, a merchant in Boston. In summer, they went up to the coast. Returned in the fall. The Oahee wintered in the Columbia River, but the Convoy proceeded to Oahoo. Returned spring 1830, and in the summer both vessels left and never returned. In 1832 a Mr. Wyeth came across by land from Boston with eleven men, with the intention of establishing a salmon fishery and expected to have met a vessel which he had sent from Boston, but he learned afterwards she had been wrecked on an island in the Pacific, and the nonarrival of his vessel obliged Mr. Wyeth to return to the United States, but his men remained in the Wallamette.
