[Extract] To St. George Tucker, 13 Aug. 1814
"I have followed the author you mention in the pizé buildings I have constructed. The foreman of my carpenters is a very intelligent man, and after frequently reading to him what appeared necessary for him to know, he made the frame & piroirs with great skill, & proceeded to build a large barn, the walls of which he completed with about 5 hands, in a day less than a month to the best of my recollection. He may sometimes have had a hand or two more than I have mentioned.
