Timber for Building Ships
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 cherrytree, 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. (Michaux 160)

François André Michaux
François André Michaux (1770-1855) should not be confused with his father André Michaux (1746–1802) whom Thomas Jefferson on behalf of the American Philosophical Society asked to lead a Western Expedition to the Pacific Ocean. Both were influential naturalists and both wrote about their travels in America. The younger’s writings show a keen interest in the prospects of the Ohio River Valley and its inhabitants. Later, he would publish his Histoire des Arbres forestiers de l’Amérique Septentrionale in three volumes between 1810 and 1813. It was translated into several English editions usually titled The North America Sylva. Thomas Nuttall completed the series with his volume North American Sylva: Trees not described by F. A. Michaux.[3]Thwaites, Travels, 15,19.
