Course of canal to Charlestown Millpond - Vintage map, Norman B. Leventhal Collection

This manuscript survey describes the course of the final 2.25 miles of the Middlesex Canal, terminating in the Charlestown Millpond. Distances are marked off in rods, and property owners indicated, as are locks, culverts crossroads (e.g., the Great Boston Road), and other features. Columns of calculations at left tally lengths of canal on different property owners' land. (From Dealer's notes.)
