Nice example of Thomson's map of the Southeastern United States, published in Edinburgh.
Thomson's map is bounded by the Atlantic, East and West Florida, the Mississippi and Missouri Rivers, Lake Erie, Pennsylvania and New Jersey.
The map features Georgia extending from the Atlantic to the Mississippi River, pre-dating Alabama and Missouri Territories.
Indiana appears in northern Virginia. Shows the 1795 Treaty Line south of Lake Erie. The Jersey Company and Illinois Company are shown just north and east of St. Louis. Ohio is named, but not delineated with color.
A number of midwestern towns, Indian Villages, Indian Tribes and forts are shown throughout the map, along with other interesting information throughout.
John Thomson (1777-ca. 1840) was a commercial map publisher active in Edinburgh. He specialized in guide books and atlases and is primarily known for his Atlas of Scotland (1832) and the New General Atlas, first published in 1817 and reissued for the next quarter century. The New General Atlas was a commercial success—it was also published in Dublin and London—and it compiled existing geographic knowledge in compelling ways for a wide audience.
His Atlas of Scotland introduced new geographic information and was the first large-scale atlas of Scotland to be organized by county. It provided the most-accurate view of Scotland available before the Clearances. Work on the atlas began in 1820 and led to Thomson’s bankruptcy in 1830 due to the high costs of gathering the latest surveys and reviewing the required materials. Despite the publication of the atlas, Thomson declared bankruptcy again in 1835.
