Gentlemen: I enclose you an Estimate of the cost of the Capitol for the Federal City upon Mr. Hallet's plan, calculated in the Philada. prices by Mr. Carstairs, one of the Architects brought forward by Dr. Thornton on the late occasion of discussing the objections offered to his plan. Altho' it may not be proper to rely entirely upon this Estimate; yet it will probably be found a very useful document in going on with the work.
In contemplating characters suitable to inspect your accounts, agreeably to your request, I have thoughts of appointing Captn. Conway,96 of Alexandria, and Major John Ross, of Bladensburg; they having struck me as Gentlemen very competent to the business in every respect, and believing them to be as little interested in the objects for which the expenditures have been
