This map details the boundary dispute between the United States and Great Britain relating to Maine. Hand coloring is used to show the boundary as claimed by the United States and by Great Britain, with a third line labeled "that of the Arbiter" which closely corresponds to Maine's present-day border with Canada. A table gives the major points of contention in this border dispute. Another table names land grants belonging to six land holders. This is the earliest of three examples of this map, printed by B. Chambers.
