and also in the book itself indicate that he had access at Mackinac to the writings of Hennepin and others, from which he plagiarized. Major Rogers, the commandant, had books relating to that region, and Carver mentions having carried books with which he mystified the Sioux Indians. But The History of the American Indians, by James Adair, from which he plagiarized, was not published until 1775 in London, and therefore the text of his Travels must have been added to and revised at later dates.

There were visions of the extension of British trade on the Pacific Ocean, and of an overland route to con- nect with it.
