In addition to the aforementioned Rolls you will find this accompanied by my account current as pay Master of the Troops at the upper posts made up to the end of the year 1797 on which you will see a balance appears in my favor amounting to 441²⁹/₁₀₀ Doll^s which sum you will please to remit as soon as convenient. An Estimate of Pay of the Troops now at the upper posts up to the first of February is now transmitted — But as there is a prob[ability of] the Detachment encreasing the estimate is not to be expected to be accurate. Blank Rolls are much wanted. I am, Sir, Your Obedient Humble Servant Isaac Craig William Simmons Esq. Acc. War Dep^t. Philadelphia
