Among the slaves were artificers of all kinds, tailors, shoemakers, carpenters, smiths, wheelwrights, and so forth; so that a plantation produced every thing within itself for ordinary use: as to articles of fashion and elegance, luxuries, and expensive clothing, they were imported from London; for the planters on the main rivers, especially the Potomac, carried on an immediate trade with England. Their tobacco was put up by their own negroes, bore their own marks, was shipped on board of vessels which came up the rivers for the purpose, and consigned to some agent in Liverpool or Bristol, with whom the planter kept an account. The Virginia planters were prone to leave the care of their estates too much to their overseers, and to think personal labor a degradation. Washington carried into his rural affairs the same method, activity, and circumspection that had distinguished him in military life. He kept his own accounts, posted up his books and balanced them with mercantile exactness. We have examined them as well as his diaries recording his daily occupations, and his letter-books, containing entries of shipments of tobacco, and correspondence with his London agents. They are monuments of his business habits. [Footnote: The following letter of Washington to his London correspondents will give an idea of the early intercourse of the Virginia planters with the mother country. "Our goods by the Liberty, Capt. Walker, came to hand in good order and soon after his arrival, as they generally do when shipped in a vessel to this river [the Potomac], and scarce ever when they go to any others; for it don't often happen that a vessel bound to one river has goods of any consequence to another; and the masters, in these cases, keep the packages till an accidental conveyance offers, and for want of better opportunities frequently commit them to boatmen who care very little for the goods so they get their freight, and often land them wherever it suits their convenience, not where they have engaged to do so. ... A ship from London to Virginia may be in Rappahannock or any of the other rivers three months before I know any thing of their arrival, and may make twenty voyages without my seeing or even hearing of the captain."] The products of his estate also became so noted for the faithfulness, as to quality and quantity, with which they were put up, that it is said any barrel of flour that bore the brand of George Washington, Mount Vernon, was exempted from the customary inspection in the West India ports.
