Saturday 5. The wind easterly, and the weather cool. The canoes being nearly finished it became necessary to dispose of our horses. They were therefore collected to the number of thirty-eight, and being branded and marked were delivered to three Indians, the two brothers and the son of a chief, who promises to accompany us down the river. To each of those men we gave a knife and some small articles, and they agreed to take good care of the horses till our return. The hunters with all their diligence are unable to kill any thing, the hills being high and rugged, and the woods too dry to hunt deer, which is the only game in the country. We therefore continue to eat dried fish and roots, which are purchased from the squaws, by means of small presents, but chiefly white beads, of which they are extravagantly fond. Some of these roots seem to possess very active properties, for after supping on them this evening, we were swelled to such a degree as to be scarcely able to breathe for several hours. Towards night we lanched two canoes which proved to be very good.
Sunday 6. This morning is again cool, and the wind easterly. The general course of the winds seems to resemble that which we observed on the east side of the mountain. While on the head waters of the Missouri, we had every morning a cool wind from the west. At this place a cool breeze springs up during the latter part of the night, or near daybreak, and continues till seven or eight o’clock, when it subsides, and the latter part of the day is warm. Captain Lewis is not so well as he was, and captain Clarke was also taken ill. We had all our saddles buried in a cache near the river, about half a mile below, and deposited at the same time a canister of powder, and a bag of balls. The time which could be spared from our labours on the canoes, was devoted to some astronomical observations. The latitude of our camp as deduced from the mean of two observations is 46 degrees 34’ 56” 3"’ north.
Monday 7. This morning all the canoes were put in the water and loaded, the oars fixed, and every preparation made for setting out but when we were all ready, the two chiefs who had promised to accompany us, were not to be found, and at the same time we missed a pipe tomahawk. We therefore proceeded without them. Below the forks this river is called the Kooskooskee, and is a clear rapid stream, with a number of shoals and difficult places. For some miles the hills are steep, the low grounds narrow, but then succeeds an open country with a few trees scattered along the river. At the distance of nine miles is a small creek on the left. We passed in the course of the day ten rapids, in descending which, one of the canoes struck a rock, and sprung a leak: we however continued for nineteen miles, and encamped on the left side of the river, opposite to the mouth of a small run. Here the canoe was unloaded and repaired, and two lead canisters of powder deposited; several camps of Indians were on the sides of the river, but we had little intercourse with any of them.
