Extremely detailed atlas of a portion of Philadelphia, the City of Brotherly Love, with marvelous hand-colored maps including a section of the Schuylkill Canal and River, which as early as 1761, was being explored for a means of transportation from Philadelphia to the modern town of Port Carbon. It was constructed by the Schuylkill Navigation Company and, at the time of its completion in 1828, the tunnel was the only one of its kind in the world. Publisher's rubberstamp to title-page "Removed to 1039 Walnut St." and with original green cloth hinges.
