Offering information about his region in response to Morse’s advertisement proposing "a system of Geography of the United States of America." "In the early part of my life, I happened to fall into the hands of the then enemies of America & was carried into Canada where I resided upwards of two years, during which time I became well acquainted with the Country adjoining to the West end of Lake Erie and between that and the Ohio, my place of residence being at Fort Detroit." Notes his varied travels, "from the Delaware to Savannah, and from Kentuckey, and Frankland, to the Atlantic." Warns Morse to be careful if he uses maps produced by Mr. Hutchins, believing his work "materially defective in the upper parts of the great Kanhawa, the Tenasee above the Cumberland Mountains, and the Kentucky and Sandy river." Offers to send information to help Morse create a "more perfect Map, than has ever yet appeared in any publication I know of." Believes Mr. Henry’s map of Virginia is "erroneous, and scarcely intelligible" in its western regions. Emphasizes his interest in "American literary productions" and the education of American youth, "an excellent means of preserving that spirit of liberty, which is the glory of the present Age." Envelope includes several docketing marks ranging from December 18, 1787, through November 26, 1794, indicating an ongoing correspondence and Campbell sending a map. "Nov. 26 1794 These documents may be relied on as accurate."
