Next day, our experiences were much the same, with the addition of a fall of snow at evening. The day following, we reached the head of a stream which directed its course more to the westward, and followed it till we discovered a large encampment of Indians. When we reached them, and alighted from our horses, we were received with great cordiality. A council was immediately assembled, white robes were thrown over our shoulders, and the pipe of peace introduced. After this ceremony, as it was too late to go any farther, we encamped, and continued smoking and conversing with the chiefs till a late hour. Next morning, we assembled the chiefs and warriors, and informed them who we were, and the purpose for which we visited their country. All this was, however, conveyed to them in so many different languages, that it was not comprehended without difficulty. We therefore proceeded to the more intelligible language of presents, and made four chiefs by giving a medal and a small quantity of tobacco to each. We received in turn, from the principal chiefs, a present, consisting of the skins of an otter and two antelopes; and were treated by the women to some dried roots and berries. We then began to traffic for horses, and succeeded in exchanging seven, and purchasing eleven. These Indians are a band of the Tushepaws, a numerous people of four hundred and fifty tents, residing on the head waters of the Missouri and Columbia Rivers, and some of them lower down the latter river. They seemed kind and friendly, and willingly shared with us berries and roots, which formed their only stock of provisions. Their only wealth is their horses, which are very fine, and so numerous that this band had with them at least five hundred. We proceeded next day, and, taking a north-west direction, crossed, within a distance of a mile and a half, a small river from the right. This river is the main stream; and, when it reaches the end of the valley, it is joined by two other streams. To the river thus formed we gave the name of Clarke's River; he being the first white man who ever visited its waters. We followed the course of the river, which is from twenty-five to thirty yards wide, shallow, and stony, with the low grounds on its borders narrow; and encamped on its right bank, after making ten miles. Our stock of flour was now exhausted, and we had but little corn; and, as our hunters had killed nothing except two pheasants, our supper consisted chiefly of berries.
