Color-coded map, entitled 'Map No 4, North America, 1750,' illustrates claims which originated from exploration and occupancy by the English, the French, and the Spanish, published in 1898. Visible are the English colonies and Newfoundland, the Hudson's Bay Company territories, New Spain and Florida, New France and Louisiana, and unexplored territories in the northwest region of the continent.
