Dear Sir ,
Inclosed herewith you will receive the Pay Bills, Abstracts of Disbursements, and Vouchers for the two last Quarters ending the 24h March, and the full amount of both, are drawn for by Capt. Elliott, the Deputy Agent, on the Acting Deputy Pay Master General Joshua Winslow Esq. although it might have been occasionally useful to me to draw my own pay separately, yet the fees of office, which Mr. Coffin was so kind as to mention to you are more than the advantages to be derived from a separate payment. I have therefore directed Capt. Elliott to draw my pay with the others as often as it becomes due, and as this is the first time of his doing so, I have thought it best to aprise you thereof that in future there may be no difficulty in the Payment of his Bills. The amount of the Pay Bills & of the Abstracts of Disbursements for the two Quarters is £1034 2s 7½d Army Pay--and Capt. Elliott has drawn for the same at thirty days sight in two separate Bills, one payable to Mr. George Leith & Co. for £837 14s[p.441] 10d and the other payable to George Sharp Esq for £196 7s 9½d both dated the 19h April 1796.
with great Regard I am Dear Sir Yours &c. &c. &c. signed A. McKee
P. S. George Girty one of the additional Interpreters died the 24h Feby last.
