This is a scarce and very unusual thematic map designed to illustrate the watersheds of the world. The map is presented on a North Polar projection. Strong hachures show the major mountain ranges and color is used to depict the watershed for each of the oceans. In North America there is a large Sea of the West and a nearly complete Northwest Passage. Australia is still shown with a conjectural coastline, making it considerably too wide. The continent connects to both New Guinea and Terre du St. Esprit (the Land of the Holy Ghost), discovered by Queiroz.
