we formed a camp at the point where the two rivers unite, near to which we found some driftwood, and were supplied by our two old chiefs with the stalks of willows and some small bushes for fuel. We had scarcely fixed the camp and got the fires prepared, when a chief came from the Indian camp about a quarter of a mile up the Columbia, at the head of nearly two hundred men: they formed a regular procession, keeping time to the noise, rather the music of their drums, which they accompanied with their voices. As they advanced they formed a semicircle round us, and continued singing for some time: we then smoked with them all, and communicated, as well as we could by signs, our friendly intentions towards all nations, and our joy at finding ourselves surrounded by our children: we then proceeded to distribute presents to them, giving the principal chief a large medal, a shirt and handkerchief; to the second chief, a medal of a smaller size, and to a third chief who came down from some of the upper villages, a small medal and a handkerchief. This ceremony being concluded they left us; but in the course of the afternoon several of them returned and remained with us till a late hour. After they had dispersed we proceeded to purchase provisions, and were enabled to collect seven dogs, to which some of the Indians added small presents of fish, and one of them gave us twenty pounds of fat dried horse-flesh. Thursday, October 17. The day being fair we were occupied in making the necessary observations for determining our longitude, and obtained a meridian altitude, from which it appeared that we were in latitude 46° 15´ 13´´ 9´´´. We also measured the two rivers by angles, and found that at the junction the Columbia is nine hundred and sixty yards wide, and Lewis’s river five hundred and seventy-five; but soon after they unite, the former widens to the space of from one to three miles, including the islands. From the point of junction the country is a continued plain, which is low near the water, from which it rises gradually, and the only elevation to be seen is a range of high country running from the northeast towards the southwest, where it joins a range of mountains from the southwest, and is on the opposite side about two miles from the Columbia. There is through this plain no tree and scarcely any shrub, except a few willow bushes; and even of smaller plants there is not much more than the prickly pear, which is in great abundance, and is even more thorny and troublesome than any we have yet seen. During this time the principal chief came down with several of his warriors and smoked with us: we were also visited by several men and women, who offered dogs and fish for sale, but as the fish was out of season, and at present abundant in the river, we contented ourselves with purchasing all the dogs we could obtain. The nation among which we now are call themselves Sokulks; and with them
