Sr. [Sir:]

In our last of the 2d Inst. [?] we informed you of the Desertion amongst our Men at the Monanegehela: Their Places we soon supply’d by Hands from Fort Cumberland and Rebstom [?] and should have finished the Line before the End of this Month. But on the 9th Ins. we cross’d a Warrior Path (used by the Six Nations to go against their enemies the Cheroquees,) there we were informed by the Chief of our Indians that he was come to the Extent of his Commission from the Six Nations to go with us on the Line; and that he would not proceed one Step further.

Finding they could not be prevailed upon to go further with the Line, we set up the Sector at the Distance of 233M[iles]. 13ch[ains]. 68 Links. from the Post marked West in Wm. Bryans Field, and found [?] we were 3 Chains 38 Links to the Southw. [?] of the line Parallel.

We are now opening a Visto in the line Parallel East [?] and have about 25 Miles to cut open: This and placing Piles of Stones on the Ridges &c (to the East of the Allegany Mountains we think we cannot finish in less than Six Weeks.[ ) ] ___We shall bring the Instruments with us, and be at Philadelphia about the End of December, if we receive no Orders to the contrary. ___We have this Day drawn a Bill on Wm. Carey for 500 £ [Pounds] and by the time we have opened the Visto above mentioned of 25 Miles (which will be in 3 Weeks) our Commissary will be in Debt Three Thousand Pounds.

We are Sr
your most obediant
humble Servants
