In addition, Washington was a partner in several great land speculations,—the Ohio Company, the Walpole Grant, the Mississippi Company, the Military Company of Adventures, and the Dismal Swamp Company; but all these ventures except the last collapsed at the beginning of the Revolution and proved valueless. His interest in the Dismal Swamp Company he held at the time of his death, and it was valued in the inventory at twenty thousand dollars. The properties that came to him from his brother Lawrence and with his wife have already been described. It may be worth noting that with the widow of Lawrence there was a dispute over the will, but apparently it was never carried into the courts, and that owing to the great depreciation of paper money during the Revolution the Custis personal property was materially lessened, for “I am now receiving a shilling in the pound in discharge of Bonds which ought to have been paid me, & would have been realized before I left Virginia, but for my indulgences to the debtors,” Washington wrote, and in 1778 he said, “by the comparitive worth of money, six or seven thousand pounds which I have in Bonds upon Interest is now reduced to as many hundreds because I can get no more for a thousand at this day than a hundred would have fetched when I left Virginia, Bonds, debts, Rents, &c. undergoing no change while the currency is depreciating in value and for ought I know may in a little time be totally sunk.” Indeed, in 1781 he complained “that I have totally neglected all my private concerns, which are declining every day, and may, possibly, end in capital losses, if not absolute ruin, before I am at liberty to look after them.” In 1784 he became partner with George Clinton in some land purchases in the State of New York with the expectation of buying the “mineral springs at Saratoga; and … the Oriskany tract, on which Fort Schuyler stands.” In this they were disappointed, but six thousand acres in the Mohawk valley were obtained “amazingly cheap.” Washington’s share cost him, including interest, eighteen hundred and seventy-five pounds, and in 1793 two-thirds of the land had been sold for three thousand four hundred pounds, and in his inventory of 1799 Washington valued what he still held of the property at six thousand dollars.
