Report of the Commission to locate the site of the frontier forts of Pennsylvania ..
This 1916 report was issued by Pennsylvania's Commission to Locate the Site of the Frontier Forts, printed at Harrisburg by the state printer, and records the surveyed positions of colonial-era forts and settlements. Its pictures are hand-drawn survey maps with fine stippling, dashed routes, and small block symbols for buildings, plus a few scaled plans of fort earthworks; a designer could borrow the terse map lettering, hatched terrain, and compass-and-scale conventions for historical or cartographic layouts.
