they compute to be two thousand one hundred miles. The barges in the spring season {63} usually take forty or fifty days to make the passage, which two or three persons in a pirogue[24] make in five and-twenty days.
What many, perhaps, are ignorant of in Europe is, that they build large vessels on the Ohio, and at the town of Pittsburgh. One of the principal ship yards is upon the Monongahela, about two hundred fathoms beyond the last houses in the town. The timber they make use of is the white oak, or quercus alba; the red oak, or quercus rubra; the black oak, or quercus tinctoria; a kind of nut tree, or juglans minima; the Virginia cherry-tree, or cerasus Virginia; and a kind of pine, which they use for masting, as well as for the sides of the vessels which require a slighter wood. The whole of this timber being near at hand, the expense of building is not so great as in the ports of the Atlantic states. The cordage is manufactured at Redstone and Lexinton, where there are two extensive rope-walks, which also supply ships with rigging that are built at Marietta and Louisville. On my journey to Pittsburgh in the month of July 1802, there was a three-mast vessel[25] of two {64} hundred and fifty tons, and a smaller one of ninety, which was on the point of being finished. These ships were to go, in the spring following, to New Orleans, loaded with the produce of the country, after having made a passage of two thousand two hundred miles before they got into the ocean. There is no doubt but they can, by the same rule, build ships two hundred leagues beyond the mouth of the Missouri, fifty from that of the river Illinois, and even
