The first 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. The map image is fine but there is some light toning or offsetting in the wide lower margin. The second map (13.3 x 13") was included in the same Senate report for historical purposes. It was extracted from Mitchell's map of 1755 by W.J. Stone. Also fine less a short binding trim tear and paper roughness along trim edge.
