He was evidently a good farmer, for in 1758 William Fairfax, who kept a friendly eye upon his absent neighbor's affairs, wrote: "You have some of the finest Tobacco & Corn I have seen this year," The summer was, however, exceedingly dry and the crop was good in a relative sense only.

Knight tried to keep affairs in good running order and the men hard at work, reporting "as to ye Carpentrs I have minded em all I posably could, and has whipt em when I could see a fault." Knight died September 9, 1758, a few months before Washington's marriage.
Washington's general manager during the Revolution was Lund Washington, a distant relative.

He was a man of energy and ability and retired against protests in 1785.

Unfortunately not much of the correspondence between the two has come down to us, as Lund destroyed most of the General's letters.

Why he did so I do not know, though possibly it was because in them Washington commented freely about persons and sections.
In one that remains, for example, written soon after his assumption of command at Cambridge, the General speaks disparagingly of some New England officers and says of the troops that they may fight well, but are "dirty fellows." When the British visited Mount Vernon in 1781 Lund conciliated them by furnishing them provisions, thereby drawing down upon himself a rebuke from the owner, who said that he would rather have had his buildings burned down than to have purchased their safety in such a way.
