at the meeting of the Commissioners at Rockfish gap it will be very important to have a copy of Madison’s map of Virginia with lines traced on it through the different places proposed for the University, so as to shew the quantum of population on each side of those lines. it should be one of those with the boundaries of the counties colored, but not their whole surface. I wrote to mr Ritchie from Poplar Forest in April to request him to forward me such an one, but not having heard from him I suppose my letter to have miscarried or some other good cause to have prevented it. will you be so good as to procure it for me, and bring or send it up. it will be safe to make enquiry of mr Ritchie in order to prevent a double execution of the request. I salute [y]ou with friendship and respect1
