Map of the Boundary Dispute

Below is a map showing details of various US and British claims, the 1831 arbitration line, and the final 1842 line set in the Treaty of Washington / Webster-Ashburton Treaty.  For a summary and history of the dispute, see my page on the Boundary Dispute.

The map is entitled "Maine Boundary Controversy, 1782-1842", and was published in Dixon Ryan Fox, Harper's Atlas of American History (New York, NY: Harper & Brothers Publishers , 1920) p.43.
