This map is another derivative of De L'Isle's 1703 North American map, as is acknowledged in the title cartouche. However, this map, published by a German cartographer, shows significant differences from other derivatives. Not only has the map been redrawn showing different island and land mass configurations (compare the shape of Florida), but also the extent of political control has changed dramatically. While the map is undated, it was apparently published in the middle of the 18th century, since it portrays a greater British presence, reflecting British territorial gains following the defeat of the French and their Spanish ally in the French and Indian War. The entire eastern portion of the continent south of the St. Lawrence River extending west to the Mississippi River is British (green), except for the solitary Florida peninsula. An indication of the diminished Spanish influence in the Caribbean is the removal of the tracts of the Spanish galleons, only to be replaced by the tracks of several British and Dutch navigators, including Sir Francis Drake, along the Pacific Coast of North America. Circa 1758.
