Ill health has hitherto prevented my proceeding to the Natural bridge to have my lines there ascertained, but I have now hopes of being able shortly to be there. I judge from your field notes that it will not be difficult to establish the three corners a. b. and c. in th[e] diagram below. our great object will be therefore to find the corner m. in Berkley’s line; for between c. and m the chain and compass will guide us on the zig-zag line to the North, the two ends of it being fixed. on my arrival at the bridge I will send a person express to ask your assistance as promptly as possible. I do not now fix the day because bad weather or ill health may delay it. I inclose a letter to Patrick Henry, open for your perusal after which I will pray you to forward1 it to him by such opportunity as occurs, and I pray you to accept the assurance of my great respect
