Captain Wyeth established his post on the Snake River, by erecting a stockade of logs, and quarters for his men, and then proceeded to the lower Columbia to receive his goods, which arrived in the _May Dacre_, Captain Lambert, from Boston, about the time he reached Fort William, on what is now known as Sauvies Island, a few miles below the mouth of the Multnomah River, now called the Wallamet. Rev. Mr. Lee and party made their first location about sixty miles from the mouth of the Wallamet, near what is now called Wheatland, ten miles below Salem. Captain Wyeth received his goods, and commenced his trading establishment, but found that, notwithstanding he was personally treated by the principal officers of the Hudson's Bay Company with great courtesy, yet it was evident that every possible underhanded and degrading device was practiced, both with the Indians and with his men, to destroy, as much as was possible, the value and profits of his trade. In the spring and summer of 1835 he supplied his Fort Hall establishment with goods. During the year 1835, the Hudson's Bay Company erected a temporary post about twelve miles up the Boise River, designed to counteract and destroy as much as possible the American fur trade established by Captain Wyeth, who continued his efforts less than three years; and, having lost of the two hundred men who had been in his employ _one hundred and sixty_ (as stated to Rev. Samuel Parker), and finding himself unable to compete with this powerful English company, he accepted Dr. McLaughlin's offer for his establishments, and left the country in 1836. In 1835, the American Board of Commissioners for Foreign Missions sent Rev. Samuel Parker and Dr. Marcus Whitman to explore the Oregon country, with a view of establishing missions among the Indians west of the Rocky Mountains. These two missionaries reached the American rendezvous on Green River, in company with the Rocky Mountain Fur Company's traders, under the direction of Captains Drips and Fitzpatrick. From the American rendezvous Mr. Parker continued his explorations in company with, and under the protection of the Nez Percé Indians, till he reached old Fort Wallawalla, now called Wallula; thence he continued in canoes to Vancouver, while Dr. Whitman returned to the United States to procure associates to establish the Nez Percé mission. CHAPTER V. Extent and power of Hudson's Bay Company.--Number of forts.--Location.--Policy.--Murder of Mr. Black.--McKay.--Manner of dealing with Indians.--Commander of fort kills an Indian.--Necessity of such a course.--Hudson's Bay Company not responsible for what their servants do. Having briefly traced the operations of the two foreign fur companies in Oregon, a knowledge of the location of their several trading establishments will enable the reader to comprehend their power and influence in the country.
