Next day the party found themselves in clover, so to speak. Game was plenty, and, as their object now was to accumulate meat for the three men who were to be left at the falls (and who were not hunters), they resolved to strike the Medicine, or Sun, River and hunt down its banks. On that river the journal, July 10, has this to say:-- “In the plains are great quantities of two species of prickly-pear now in bloom. Gooseberries of the common red kind are in abundance and just beginning to ripen, but there are no currants. The river has now widened to one hundred yards; it is deep, crowded with islands, and in many parts rapid. At the distance of seventeen miles, the timber disappears totally from the river-bottoms. About this part of the river, the wind, which had blown on our backs, and constantly put the elk on their guard, shifted round; we then shot three of them and a brown bear. Captain Lewis halted to skin them, while two of the men took the pack-horses forward to seek for a camp. It was nine o’clock before he overtook them, at the distance of seven miles, in the first grove of cottonwood. They had been pursued as they came along by a very large bear, on which they were afraid to fire, lest their horses, being unaccustomed to the gun, might take fright and throw them. This circumstance reminds us of the ferocity of these animals, when we were last near this place, and admonishes us to be very cautious. We saw vast numbers of buffalo below us, which kept up a dreadful bellowing during the night. With all our exertions we were unable to advance more than twenty-four miles, owing to the mire through which we are obliged to travel, in consequence of the rain.” The Sun, or Medicine, River empties into the Missouri just above the great falls of that stream; and near here, opposite White Bear Islands, the expedition had deposited some of their property in a cache dug near the river bank, when they passed that way, a year before. On the thirteenth of the month, having reached their old camping-ground here, the party set to work making boat-gear and preparing to leave their comrades in camp well fixed for their stay. The journal adds:-- “On opening the cache, we found the bearskins entirely destroyed by the water, which in a flood of the river had penetrated to them. All the specimens of plants, too, were unfortunately lost: the chart of the Missouri, however, still remained unhurt, and several articles contained in trunks and boxes had suffered but little injury; but a vial of laudanum had lost its stopper, and the liquid had run into a drawer of medicines, which it spoiled beyond recovery. The mosquitoes were so troublesome that it was impossible even to write without a mosquito bier. The buffalo were leaving us fast, on their way to the southeast.” One of the party met with an amusing adventure here, which is thus described:--
