Date estimated based on the apparent library acquisition date usually stamped on the back of the map sheet. Mounted on linen in 6 panels. Comparing our sheets to those at the Library of Congress shows that most of our sheets were published 5 to 10 years before the stamped acquisition date. A few sheets are duplicated and placed under similar list numbers. This map series is remarkable for the level of fine detail. As a consequence, it was scanned at 800 PPI providing four times the resolution of the typical detailed map scan of 400 PPI. At least ten separate symbols for special buildings were utilized, a method enhanced by placing an abbreviation next to the symbol. Structures with special symbols include: churches, chapels, monuments, windmills, water mills, stamp mills, forester's lodges, watchtowers, ruins, forts, quarries, clay pits, lime kilns, and coke-ovens. Factories, brick works, powder magazines electric power plants, and many other important buildings are differentiated by means of abbreviation. Houses appear as black blocks, either rectangular or shaped like the ground plan of the building. Many other features are differentiated, for example there are four different qualities of roads plus bridle paths and footpaths. Vegetation is minutely classified including separate symbols for broadleaf trees, evergreens, underbrush, heather, dry meadows, wet meadows, swamps, orchards, gardens, vineyards, and parks. Relief is shown by hachures. Spot elevations are given in meters above sea level.
