Fort Umpqua was located in the extreme southwestern part of Oregon, near the mouth of the river bearing that name. It was a temporary stockade built of logs, overlooking a small farm in its immediate vicinity, was generally occupied by a clerk and from four to eight Frenchmen.
Fort George (Astoria) already described.
They had a farm and small establishment at the mouth of the Cowlitz, and a more extensive farm some twenty-five miles up that river.
Fort Vancouver,—a stockade, six miles above the mouth of the Multnomah, or Wallamet River. This fort was the general depot for the southwestern department, at which their goods for Indian trade were landed, and their furs and peltries collected and shipped to foreign markets. There was also a trading-house at Champoeg, some thirty-five miles up the Wallamet River.
On the left bank of the Columbia River, near the 46° of north latitude, stood Fort Nez Percés, called Wallawalla, now Wallula,—a stockade, accidentally burned in 1841, and rebuilt with adobes in 1841-2.
On the left bank of the south branch of the Columbia, or Snake River, at the junction of the Boise, was located Fort Boise, built formerly, in 1834, with poles; later, with adobes.
Continuing up Snake River to the junction of the Portneuf, on its left bank we find Fort Hall, built by Captain Wyeth; a stockade in 1834; rebuilt by the Hudson’s Bay Company, with adobes, in 1838.
Thence up the Columbia, Fort Okanagon, at the mouth of Okanagon River, formerly a stockade, latterly a house or hut; and up the Spokan some twenty miles, was the old Spokan Fort, built by Astor’s Company, a stockade with solid bastions.
Continuing up the Columbia to Kettle Falls, and two miles above, on the left bank is Fort Colville, formerly a stockade, still occupied by the Hudson’s Bay Company.
Thence up the Columbia to the mouth of the Kootanie River, near the forty-ninth parallel of latitude, is the trading establishment called Kootanie House. Thence returning south, and ascending the Flathead (Clark’s) and Kootanie rivers, into what is now Montana Territory, is, or was, the hut called Flathead House. Still higher up on the Columbia was a small establishment, called the boat encampment, or Mountain House.
