Preston, John B. (Surveyor General).
Washington, D.C. Surveyor Generals Office. 1852.
Map, 47 1/2 x 16 inches on sheet size 53 x 16 3/4 inches, folded as issued (3 vertical folds, 8 horizontal folds) on two conjoined sheets. Very tight left margin, but neatline is present; tiny piece (1/2 x 1/8th inch) at second crease down from top left has been reattached on verso with acid free tape; tape reinforcement on verso at five fold intersections; splits at upper edge fold lines, well outside the map neatline; split at second fold line down at right edge just touching image; a few soft printers' folds. Overall a very good clean and bright example of this very large and scarce map. A detailed record of settlement in the Pacific Northwest at a moment of rapid change, this huge map dated October 21st, 1852 contains vastly more detailed information than the earlier issue of October 1851. At lower right of the map is a key to the current state of surveying and subdivision of this western portion of the Oregon Territory with the markings which identify "Townships Subdivided" in the previous year's survey marked with a circle, a plus sign for townships proposed to be surveyed in 1853, and an inverted V for those to be surveyed in 1854. The map extends north to Bellingham Bay and Mt. Baker; the first surveying in what was to become Washington Territory (in the area around Steilacom and Olympia) is slated for 1854. The map is identified as Senate Ex. doc No 1, 2d Sess. 32nd Congress, and was printed by A. Hoen company in Baltimore. This particular oversized map publication appears to be far scarcer than Surveyor General maps of the area published in preceding and subsequent years, with only one institutional holding as a map, at the University of Texas Arlington OCLC number 776243353.
