The boundary between Maine and the British colonies remained a matter of contention between the United States and Great Britain for nearly sixty years after the Treaty of Paris of 1783. This map shows the northernmost extent of U.S. claims (which notably included Lake Temiscouata, now in Quebec) as well as the territory claimed by Britain and the compromise line proposed in the early 1830s by the King of the Netherlands. It also acknowledges the Native and French settlements on the upper course of the St. John River, John Baker's settlement, and the British garrison near Grand Falls. The two sides would reach an agreement in 1842.

This map shows the expansion of settlement inland from the coasts in the southern part of the state and, highlighted in different colors, Maine's counties. Aroostook County was established in 1839.

The map appeared in An Illustrated Atlas, Geographical, Statistical, and Historical of the United States and Adjacent Countries, published in Boston by Weeks, Jordan, and Company in 1838.
