"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.
"July 9.—The boat having now become sufficiently dry, we gave it a coat of the composition, then a second, and launched it into the water. She swam perfectly well. The seats were then fixed, and the oars fitted. But after a few hours' exposure to the wind, which blew with violence, we discovered that nearly all the composition had separated from the skins, so that she leaked very much. To repair this misfortune without pitch was impossible; and, as none of that article was to be procured, we were obliged to abandon her, after having had so much labor in the construction.
"It now becomes necessary to provide other means for transporting the baggage which we had intended to stow in her. For this purpose, we shall want two canoes; but for many miles we have not seen a single tree fit to be used for that purpose. The hunters, however, report that there is a low ground about eight miles above us by land, and more than twice that distance by water, in which we may probably find trees large enough. Capt. Clarke has therefore determined to set out by land for that place, with ten of the best workmen, who will be occupied in building the canoes, till the rest of the party, after taking the boat to pieces and making the necessary deposits, shall transport the baggage, and join them with the other six canoes.
"Capt. Clarke accordingly proceeded on eight miles by land; the distance by water being twenty-three miles. Here he found two cottonwood-trees, and proceeded to convert them into boats. The rest of the party took the iron boat to pieces, and deposited it in a cache, or hole, with some other articles of less importance.
"July 11.—Sergeant Ordway, with four canoes and eight men, set sail in the morning to the place where Capt. Clarke had fixed his camp. The canoes were unloaded and sent back, and the remainder of the baggage in a second trip was despatched to the upper camp.
"July 15.—We rose early, embarked all our baggage on board the canoes, which, though eight in number, were heavily laden, and at ten o'clock set out on our journey.
"July 16.—We had now arrived at the point where the Missouri emerges from the Rocky Mountains. The current of the river becomes stronger as we advance, and the spurs of the mountain approach towards the river, which is deep, and not more than seventy yards wide. The low grounds are now but a few yards in width; yet they furnish room for an Indian road, which winds under the hills on the north side of the river. The general range of these hills is from south-east to north-west; and the cliffs themselves are about eight hundred feet above the water, formed almost entirely of a hard black rock, on which are scattered a few dwarf pine and cedar trees.
"As the canoes were heavily laden, all the men not employed in working them walked on shore. The navigation is now very laborious. The river is deep, but with little current; the low grounds are very narrow; the cliffs are steep, and hang over the river so much, that, in places, we could not pass them, but were obliged to cross and recross from one side of the river to the other in order to make our way."
