Now take a look at the first Mitchell Map. What are the names of the different territories on this map? Can we tell what belongs to the United States and what doesn't? How?

What belongs to America are as follows:

Sandusky, Ohio;Missouri River: Missouri River is reckoned to run Westward towards the Mountains of New Mexico, as far as the Ohio does Eastward;Present-day Iowa: Extensive Meadows full of Buffaloes formed the present day Iowa;Central Pennsylvania, north of present-day Harrisburg: St. Anthony's Wilderness;South Georgia: country of the Apalachees;North Florida: TIMOOQUA;Alabama area: The English has Factories & Settlements in all the Towns of the Creek Indians of any note, except Albamas; e.t.c

What does not belong to America are inter alia:

The supposition that the Mississippi River extended north towards the 50th parallel into British territory;U.S.A –Canada border was not clearly drawn from Maine to the Oregon Country;Inconsistencies that created Minnesota's Northwest Angle;Inaccuracy in depicting where an east-west line drawn through the southernmost point of Lake Michigan would intersect Lake Erie;
