Sheet No. 4. Photo-Lithographic Copy Of The Detailed Maps Of The North West Boundary ...Between The United States And The British Possessions Under the Treaty of June 15th 1846. (Little Dalles and Yome-tsin Creek to Rock Creek, Washington Territory and British Columbia). | Photo-Lithographic Copy Of The Detailed Maps Of The North West Boundary From Points Roberts To The Rocky Mountains Between The United States And The British Possessions Under the Treaty of June 15th 1846 Showing Monuments, Cuts and other Marks. Archibald Campbell U.S. Com'r N.W. Boundary Survey. Photolith. by New York Lithog. Engrg. & Printg. Co. Julius Bien Supt. ... | 7 very large and detailed maps of the boundary. The maps are undated and not listed specifically in any sources we can locate. The final report on the Northern Boundary Survey was never published (Wheat) and these maps may be the only published evidence. The two maps cited and reproduced by Wheat are manuscript general maps by J. Parke. The seven maps here are two times enlargements of the seven detailed maps that accompanied the two general maps (The title map sheet (#7) says the maps are "enlarged to twice the scale of original drawings;" Wheat, vol five, page 163, says "the two general maps (Wheat 1144-45)...are backed up by seven detailed sheets exhibiting the land boundary..."). Wheat also mentions studies by Baker and Deutsch that might definitively answer this question. These maps are unusual in appearance because of the photolithographic enlargement - a great deal of detail is apparent. When put together end to end the seven sheets are about forty feet long. Map is without color.
