Regarding North-South Boundary Between the State of Maryland and the State of Delaware. In 1731, the fifth Lord Baltimore petitioned King George II for an official resolution of the boundary dispute. In the ensuing negotiations the Calverts tried to hold out for the 40th parallel, but Pennsylvania colonists had settled enough land to the west and southward of Philadelphia that this was no longer practical. In 1732 the parties agreed that the boundary line should run east from Cape Henlopen to the midpoint of the peninsula, then north to a tangency with the west side of the twelve-mile radius arc around New Castle, then around the arc to its northernmost point, then due north to an east-west line 15 miles south of Philadelphia. It was a bad deal for the Calverts. The east-west line would turn out to be about 19 miles south of the 40th parallel, and, as the map appended to the agreement shows, would intersect the arc. The map placed ‘Cape Hinlopen’ at what is now Fenwick Island, almost 20 miles to the south as well; this error was an attempt at deception, not ignorance .
