From the Right Reverend James Madison
Feb. 12th. 1804 Wmsburg.
I am much obliged to you for the Map, which you were so good as to procure, & forward.1 It is, probably, the best Authority for the Delineation of the Potommac, from Washington, & will be followed.
I thank you also for communicating Mr Moores2 determination of the Long. of the federal City. If it can be relied upon, & I suppose it may, from his Character, it proves no inconsiderable Error in the Geographers who have preceeded. I wish Mr Moore could favour me with the observations, from which his Result is drawn.
Any Communications within three or four Weeks from you, will be very acceptable. Perhaps Mr. Jefferson may possess some useful Materials; but knowing the perpetual Occupation which his Office must give him, I cannot add to his Burthen.
I have found, simple as the Business may appear, that he who engages, honestly, to make a Map of Virga. prepares for himself a Herculean Task. I flatter myself however, that my Map will be found useful. It is to be engraved by Bossier,3 a Swiss Artist, who was recommended to the Pr. by Genl. Kosciusko.
