Superb map of the continent published during the transitional period leading up to the American Revolution. The map shows much of the region controlled by the British after the French and Indian War. Several of the colonial charters extend to an indeterminate western boundary. The charter and dates are noted along the colonial boundaries, which extend through Louisiana, a Spanish possession at the time. Another conflicting boundary is New Mexico's eastern line, which travels north along the R. Mexicano (Sabine River) before turning northwest where it intersects with Virginia and Carolina's border. This map, finely engraved by Thomas Kitchin, shows a good amount of detail regarding topography and watershed, Indian lands, settlements, fishing banks, and more.
