[Copied Dec. 5. 1857 Winthrop Sargent] [Rec^d. Dec. 10 1857] January 4, 1794. Dear Sir, I enclose you three estimates of the expence of building and equipping frigates. N^o. 1 — Was made in the year 1790 in this city, and is in general the most perfect; but the wages of the men were then placed greatly too low. N^o. 2 — is an estimate made in the same year in Boston, and I believe is pretty accurate, but not comprehending all the equipments. N^o. 3 — is an estimate made Recently in this city, and may be considered as tolerably accurate of those articles which it comprehends, but there has not been sufficient time to obtain perfect information. I am Sir, Respectfully, Your obed^t. Serv^t. H. Knox. Thomas Fitzsimons, Esq.
