"June 29.--Capt. Clarke, having lost some notes and remarks which he had made on first ascending the river, determined to go up along its banks in order to supply the deficiency. He had reached the falls, accompanied by his negro-servant York, and by Chaboneau, the half-breed Indian interpreter, and his wife with her young child. On his arrival there, he observed a dark cloud in the west, which threatened rain; and looked around for some shelter. About a quarter of a mile above the falls he found a deep ravine, where there were some shelving rocks, under which they took refuge. They were perfectly sheltered from the rain, and therefore laid down their guns, compass, and other articles which they carried with them. The shower was at first moderate; it then increased to a heavy rain, the effects of which they did not feel. Soon after, a torrent of rain and hail descended. The rain seemed to fall in a solid mass, and, instantly collecting in the ravine, came rolling down in a dreadful torrent, carrying the mud and rocks, and every thing that opposed it. Capt. Clarke fortunately saw it a moment before it reached them, and springing up, with his gun in his left hand, with his right he clambered up the steep bluff, pushing on the Indian woman with her child in her arms. Her husband, too, had seized her hand, and was pulling her up the hill, but was so terrified at the danger, that, but for Capt. Clarke, he would have been lost, with his wife and child. So instantaneous was the rise of the water, that, before Capt. Clarke had secured his gun and begun to ascend the bank, the water was up to his waist; and he could scarce get up faster than it rose, till it reached the height of fifteen feet, with a furious current, which, had they waited a moment longer, would have swept them into the river, just above the falls, down which they must inevitably have been carried. As it was, Capt. Clarke lost his compass, Chaboneau his gun, shot-pouch, and tomahawk; and the Indian woman had just time to grasp her child before the net in which it lay was carried down the current." PROGRESS RESUMED. "July 4.--The boat was now completed, except what was in fact the most difficult part,--the making her seams secure. Having been unsuccessful in all our attempts to procure tar, we have formed a composition of pounded charcoal with beeswax and buffalo-tallow to supply its place. If this resource fail us, it will be very unfortunate, as, in every other respect, the boat answers our purpose completely. Although not quite dry, she can be carried with ease by five men: she is very strong, and will carry a load of eight thousand pounds, with her complement of men.
