Great expectations were entertained of the boat that was built here on the iron frame brought all the way from Harper’s Ferry, Virginia. The frame was covered with dressed skins of buffalo and elk, the seams being coated with a composition of powdered charcoal and beeswax, in default of tar or pitch. This craft was well named the “Experiment,” and a disappointing experiment it proved to be. Here is Captain Lewis’ account of her failure: “The boat having now become sufficiently dry, we gave her a coat of the composition, which after a proper interval was repeated, and the next morning, Tuesday, July 9th, she was launched into the water, and swam perfectly well. The seats were then fixed and the oars fitted; but after we had loaded her, as well as the canoes, and were on the point of setting out, a violent wind caused the waves to wet the baggage, so that we were forced to unload the boats. The wind continued high until evening, when to our great disappointment we discovered that nearly all the composition had separated from the skins and left the seams perfectly exposed; so that the boat now leaked very much. To repair this misfortune without pitch is impossible, and as none of that article is to be procured, we therefore, however reluctantly, are obliged to abandon her, after having had so much labor in the construction. We now saw that the section of the boat covered with buffalo-skins on which hair had been left answered better than the elk-skins, and leaked but little; while that part which was covered with hair about one-eighth of an inch retained the composition perfectly, and remained sound and dry. From this we perceived that had we employed buffalo instead of elk skins, not singed them so closely as we did, and carefully avoided cutting the leather in sewing, the boat would have been sufficient even with the present composition; or had we singed instead of shaving the elk-skins, we might have succeeded. But we discovered our error too late; the buffalo had deserted us, and the travelling season was so fast advancing that we had no time to spare for experiments; therefore, finding that she could be no longer useful, she was sunk in the water, so as to soften the skins, and enable us the more easily to take her to pieces.
