FIRST EDITION, published at Benjamin Franklin's expense. "One of the principal causes of the hostility of the Pennsylvania Indians, was the wicked craft practiced upon them by Governor Thomas Penn, and other proprietors in 1737. Certain chiefs having been called together by the speculators, two persons were found to testify that they were present at a council fifty years before, at which as much land was ceded to William Penn, as a man could walk around in a day and a half... To locate as large a territory as possible, a trained pedestrian was employed, who was met at appointed stations by refreshments, and thus was enabled to traverse a route which cut off a million acres from the Indian territory. Less than one third that quantity of land was the amount which the Indians had been led to expect would be ceded. Endless conferences, and numerous councils, were followed by bloody massacres, that devastated the border settlements of Pennsylvania and Virginia, for twenty years" (Field). Charles Thompson's integrity was so highly valued by the Indians that they chose him to record proceedings at the Treaty of Easton in 1757. He became most famous as the perpetual secretary of the Continental Congress, recording the birth and development of the American nation. Church 1029; Field 1548; Howes T-210; Sabin 95562; Vail 535.
