Isaac Craig, Esquire. Pittsburgh D. of War Accountants Off[ice] Septem.^r 3. 179[—] Sir Your letter of the 28.^th ult^o. I ha[ve] received and the sum of Two thousand, five hundred and seventy[—] Dollars agreeably to your Receipt for that sum, will be placed t[o] the debit of your Account on the Books of this Office. — A[s] there is so continued a Variation in the Number of Troops at the upper Posts of The Ohio. I could wish that you would from time to time transmit Estimates to this Office of the probable amount of the Pay, Subsistence and Forage. Which may become due to them — say every two Months — The reason for my making this request is that I am at a loss to know how to form the estimates accurately owing to my not being in posesion of Muster Rolls. It would also be a desireable thing if You would forward quar- -terly a Statement of the Money you received and ex- -pended. It would answer as a Check on the entry to your debit, and Credit on the Books of this Office. You will please therefore forward a Statement up to the last of the present Months — shewing the Balance (if any) remaining in your hands. I am &c. William Simm[s]
