To George Gilpin
Mount Vernon Octr 29th 1785.
As you were so obliging sometime ago as to offer me the use of your Scow to enable me to get mud from the bed of the River to try the efficacy of it as a manure; I would thank you, if it is convenient, for the lent of it next Week, & will send up for it on Monday, if you will let me know to what place, and of whom it is to be had.1
I will avail myself also of your kind offer of getting me a Water level & staff made, in the best manner. I have joiners that could execute the Wooden Work as well as it can be done any where, but my Smith is too great a bungler to entrust anything to him that requires skill, or exactness; for which reason, if you conceive, by furnishing me with the Iron part of the level, I could not get the Wood well put to it here, I would thank you for the whole, compleat, & will pay the Workmen who do the seperate parts, with pleasure. Conceiving that the length of the level contributes to the truth of it, I beg, if the whole is made with you, that mine may not be less than four feet. With great esteem & regard I am—Dr Sir—Yr Obedt Sert
1. See GW to Arthur Donaldson, 16 Oct., regarding GW’s plans to experiment with using mud from the Potomac as fertilizer. Monday was 31 Oct., and Gilpin was not able to send his scow until later in the week (see GW to Gilpin, 1 Nov.). GW’s entry for 3 Nov. in his diary includes: “Borrowed a Scow from Colo. Gilpin, with which to raise Mud from the Bed of the river or Creek, to try the efficacy of it as a Manure, and sent it to the river Plantation for that purpose. Went over there myself to mark off a piece of ground to spread it on, after it should get mellowed by the frosts of the Winter” (Diaries description begins Donald Jackson and Dorothy Twohig, eds. The Diaries of George Washington. 6 vols. Charlottesville, Va., 1976–79. description ends , 4:217–18). GW does not again refer in his diary to this particular mud.
