This map is an unrecorded manuscript of the northeast part of the British colonies in America, showing in some detail the topography of the region and including names of towns, rivers, and harbors. Possibly produced for military purposes during the rise of hostilities between the French and English in America, the cartography appears to be based on both original French and English sources. The geographic coverage of this map shows the North American coast from Casco Bay to Cape May, extending inland as far as Lake Ontario. It encompasses the British colonies in New England, as well as New York, New Jersey, and part of Pennsylvania.
