London: printed for J. Wilkie, at the Bible, in St. Paul's Churchyard, 1759. First edition. 22cm. 184 pp. Frontis. folding engraved map by T[homas] Jefferys: "A Map of the Province of Pensylvania [sic]. intended chiefly to Illustrate the Account of the Several Indian Purchases made by the Proprietaries of the said Province the Claims made by the Indians, on Lands Settled and not Purchased of them and the Tract they now desire may be allotted for them Solely." Contemporary 3/4 leather and marbled paper boards (paper heavily chipped), old paper spine label with abbreviated title in ink, laid down, ink title on front board partially rubbed away, title page with wear and rubbing to fore edge likely caused by the folded edge of the map, with some loss to a few letters in the publication information, blank rear endpaper lacking. This copy belonged to James Moon (his signature, dated 1761, on endpapers, along with two other members of the Moon family, likely part of a Quaker family who lived in Bucks Co., Pennsylvania for several generations). The map has two 5cm. tears across the lower right corner just extending into the image, and one short vertical split affecting a few letters, some old paper reinforcements along folds on verso; explanation of the map, printed in type at the right margin is intact. Occasional pencil notes in margins of text.
Charles Thomson, later secretary of the Continental Congress, was, at the time this was written, an usher at a Quaker grammar school in Philadelphia [see: Church 1029], and was considered trustworthy by the native tribes. Both Thomson's account, "written to protest the Pennsylvania proprietors' abusive treatment of the Indians which was turning them against the English," and Post's journal were apparently printed at Benjamin Franklin's expense "as part of his campaign to discredit the Proprietary government of Pennsylvania." [Streeter 2: 966]. Item #63065
Graff 4139: "Thomson's account considered the reasons for the alienation of the Indian tribes from the grasping colonial government of Pennsylvania. It was one of the most important books on relations with the Indians that had been published up to that time. Also notable was the appearance of the Journal of Christian Frederick Post, an intrepid Moravian missionary who almost single-handedly won over to the English side the support of the Indians along the Ohio River."
Field 1548: "Mr. Thomson's work fully analyzes the cause of the alienation, which the heroic Quaker, Christian Post, hazarded his life to overcome."
