and closely strung together round their necks. They had among them a few fowling-pieces, but they were, in general, armed with bows and arrows. Beyond the village of the Yanktons the country, on both sides of the river, was low, and, for the most part, destitute of timber; but, in some places, it was covered with cotton-wood, elm, and oak. The weather had been intensely hot; but, in the beginning of September, the wind was violent, and the weather cold and rainy. On the second of this month, the hunters killed four elks, and the whole party was supplied with an abundance of grapes and plums, which grew wild near the river. They this day observed, on the south side of the Missouri, the remains of an ancient Indian fortification, formed chiefly of walls of earth. On the 7th of September the weather was very cold. The voyagers, this evening, encamped at the foot of a round mountain, about three hundred feet in height, which, at a distance, had the appearance of a dome. In this part of the country the hunters chiefly killed elks, deer, and squirrels: and they occasionally brought in beavers, porcupines, and foxes. On the 12th they passed an island covered with timber; and they had great difficulty in struggling through the sand-bars, the water being both rapid and shallow. The weather was now becoming so cold, that it was requisite to give out flannel-shirts to the men; and several animals were killed, for the sake of their skins to cover the boats. In many places the strong current of the river had worn away the banks, to considerable extent. An interview took place, on the 25th, with some chiefs of the _Tetons_, a tribe of the Sioux Indians: nearly the same ceremonies and agreements were used and entered into, as with the preceding tribes; and similar presents were made. They promised obedience to the "great father," but they soon showed how little dependance could be placed on the promises of uncivilized nations. As they were going away, a party of them endeavoured to seize one of the boats, declaring that they had not received presents enough. On being told they should receive no more, they drew their arrows from their quivers, and were bending their bows, when the swivel-gun in one of the boats was levelled at them. Perceiving from this that the most determined resistance would be made, they at length ceased from their claims. On the ensuing day these Indians approached the banks of the river, accompanied by their wives and children, and by a great number of their friends. Their disposition now seemed friendly, and the voyagers accepted an invitation to remain, during the night, on shore, to witness a dance which was preparing for their entertainment.
