PLAN of the TOWN AND CHART of the HARBOUR of BOSTON Exhibiting a View of the Islands, Castle Forts and Entrances into the said Harbour
This chart documents the Port of Boston at the dawn of the American Revolution. Under the strain of the Boston Port Act imposed during the winter of 1774-75, New Englanders continued to agitate against their British government. An article accompanying the map is entitled “An Account of the Proceedings of the American Colonists since the Passing of the Boston Port Bill.” It informs the readers that the Governor had assured the town that “he will do all in his power to secure the peace and good order of the town" and goes on to list “the regiments, & companies now at Boston.” An English map of the seaward approach to Boston during the American Revolutionary War with a compass rose showing rhumb lines for the British sailors planning to enter the harbour. Soundings are taken around the islands and in the channels and guts. Dangerous rocks are marked by crosses, and sand banks by broken lines. Forts throughout the harbour are shown, and urban areas are symbolized by hatching.
A line a lattidue and a line of longitude intersect at Boston detailing degrees north from the equator and west from the London Prime Meridian. The scale was calculated by the map's scale bar, and the coordinated were derived via georeferencing.
