"To accompany Campbell's Report on the Boundary. Originally issued in unbound folio. The boundary between the United States and Canada was set by the Oregon Treaty of 1846 but the surveying of the boundary was interrupted by the Civil War and not completed until 1875. These maps are highly detailed and show many cultural features along the boundary. The lithographic work is excellent." - David Rumsey Historical Map Collection
