Shortly after midnight the sleepers were startled by the sergeant on guard crying out that the sand-bar was sinking, and the alarm was given; for scarcely had they got off with the boats before the bank under which they had been lying fell in; and by the time the opposite shore was reached the ground on which they had been encamped sunk also. A man who was sent to step off the distance across the head of the bend made it but two thousand yards, while its circuit is thirty miles. On the 22d they passed a creek and two islands, known by the name of the Three Sisters, where a beautiful plain extended on both sides of the river. This is followed by an island on the north, called Cedar Island, about one mile and a half in length, and the same distance in breadth, and deriving its name from the quality of its timber. On the south side of this island is a fort and a large trading-house, built by a Mr. Loisel in order to trade with the Sioux, the remains of whose camps are in great numbers about this place. The establishment is sixty or seventy feet square, built with red cedar, and picketed in with the same materials.
The next day, in the evening, three boys of the Sioux nation swam across the river, and informed them that two parties of Sioux were encamped on the next river, one consisting of eighty and the second of sixty lodges, at some distance above. After treating them kindly, they sent them back with a present of two carrots of tobacco to their chiefs, whom they invited to a conference in the morning.
September 24.—At an island a few miles above Highwater Creek they were joined by one of their hunters, who [proceeds the narrative] procured four elk; but while he was in pursuit of the game the Indians had stolen his horse. We left the island, and soon overtook five Indians on the shore; we anchored, and told them from the boat we were friends, and wished to continue so, but were not afraid of any Indians; that some of their young men had stolen the horse which their great father had sent for their great chief, and that we could not treat with them until he was restored. They said they knew nothing of the horse, but if he had been taken he should be given up. We went on, and at thirteen and a half miles we anchored one hundred yards off the mouth of a river on the south side, where we were joined by both the pirogues, and encamped; two-thirds of the party remained on board, and the rest went as a guard on shore, with the cooks and one pirogue; we have seen along the sides of the hills on the north a great deal of stone; besides the elk, we also observed a hare; the five Indians whom we had seen followed us, and slept with the guard on shore. Finding one of them was a chief, we smoked with him, and made him a present of tobacco. This river is about seventy yards wide, and has a considerable current. As the tribe of the Sioux which inhabit it are called Tetons, we gave it the name of Teton River.
[On the 25th they met a party of Indians who threatened violence, and attempted to detain them by force, but were induced to desist by a threatening attitude on the part of the whites.]
September 26.—Our conduct yesterday seemed to have inspired the Indians with fear of us; and as we were desirous of cultivating their acquaintance, we complied with their wish that we should give them an opportunity of treating us well, and also suffer their squaws and children to see us and our boat, which would be perfectly new to them. Accordingly, after passing, at one and a half miles, a small willow island and several sand-bars, we came to on the south side, where a crowd of men, women, and children were waiting to receive us. Captain Lewis went on shore, and remained several hours; and observing that their disposition was friendly, we resolved to remain during the night to a dance, which they were preparing for us. Captains Lewis and Clarke, who went on shore one after the other, were met on landing by ten well-dressed young men, who took them up in a robe, highly decorated, and carried them to a large council-house, where they were placed on a dressed buffalo-skin by the side of the grand chief. The hall, or council-room, was in the shape of three-quarters of a circle, covered at the top and sides with skins well dressed and sewed together. Under this shelter sat about seventy men, forming a circle round the chief, before whom were placed a Spanish flag and the one we had given them yesterday.
This left a vacant circle of about six feet in diameter, in which the pipe of peace was raised on two forked sticks, about six or eight inches from the ground, and under it the down of the swan was scattered; a large fire, in which they were cooking provisions, stood near, and in the centre about four hundred pounds of excellent buffalo-meat, as a present for us.
As soon as we were seated an old man got up, and after approving what we had done, begged us to take pity on their unfortunate situation. To this we replied with assurances of protection. After he had ceased, the great chief rose and delivered an harangue to the same effect; then, with great solemnity, took some of the most delicate parts of the dog which was cooked for the festival, and held it to the flag by way of sacrifice; this done, he held up the pipe of peace, and first pointed it towards the heavens, then to the four quarters of the globe, and then to the earth, made a short speech, lighted the pipe, and presented it to us. We smoked, and he again harangued his people, after which the repast was served up to us. It consisted of the dog which they had just been cooking, this being a great dish among the Sioux, and used on all festivals; to this were added pemitigon, a dish made of buffalo-meat, dried or jerked, and then pounded and mixed raw with grease and a kind of ground potato, dressed like the preparation of Indian corn called hommony, to which it is little inferior. Of all these luxuries, which were placed before us in platters with horn spoons, we took the pemitigon and the potato, which we found good, but we could as yet partake but sparingly of the dog.
We ate and smoked for an hour, when it became dark; everything was then cleared away for the dance, a large fire being made in the centre of the house, giving at once light and warmth to the ball-room. The orchestra was composed of about ten men, who played on a sort of tambourine, formed of skin stretched across a hoop, and made a jingling noise with a long stick to which the hoofs of deer and goats were hung; the third instrument was a small skin bag with pebbles in it; these, with five or six young men for the vocal part, made up the band. The women then came forward, highly decorated; some with poles in their hands, on which were hung the scalps of their enemies; others with guns, spears, or different trophies taken in war by their husbands, brothers, or connections.
Having arranged themselves in two columns, one on each side of the fire, as soon as the music began they danced towards each other till they met in the centre, when the rattles were shaken, and they all shouted and returned back to their places. They have no step, but shuffle along the ground; nor does the music appear to be anything more than a confusion of noises, distinguished only by hard or gentle blows upon the buffalo-skin; the song is perfectly extemporaneous. In the pauses of the dance some man of the company comes forward and recites, in a sort of low guttural tone, some little story or incident, which is either martial or ludicrous, or, as was the case this evening, voluptuous and indecent; this is taken up by the orchestra and the dancers, who repeat it in a higher strain and dance to it. Sometimes they alternate, the orchestra first performing, and when it ceases the women raise their voices, and make a music more agreeable, that is, less intolerable, than that of the musicians.
The dances of the men, which are always separate from those of the women, are conducted very nearly in the same way, except that the men jump up and down instead of shuffling; and in the war-dances the recitations are all of a military cast. The harmony of the entertainment had nearly been disturbed by one of the musicians, who, thinking he had not received a due share of the tobacco we had distributed during the evening, put himself into a passion, broke one of the drums, threw two of them into the fire, and left the band. They were taken out of the fire; a buffalo robe, held in one hand, and beaten with the other by several of the company, supplied the place of the lost drum or tambourine, and no notice was taken of the offensive conduct of the man. We stayed till twelve o’clock at night, when we informed the chiefs that they must be fatigued with all these attempts to amuse us, and retired, accompanied by four chiefs, two of whom spent the night with us on board....
