Part One From Ohio to the Coast
The Oregon Country is shown as part of the United States, although the whole region was in dispute between the United States and Great Britain. In the United States itself the settled part of the country was east of the dotted line that runs from Lake Ontario to the Gulf of Mexico. West of this line was the Indian country, with only a few forts as outposts of settlement. Several territories had been organized, but Oregon, Missouri, and Nebraska were little more than names for vast undetermined regions.
