 Maryland insisted that the boundary be drawn at the fortieth parallel as specified in the Charter, while Pennsylvania proposed that it be drawn by an elaborate method which purported to compensate for the geographic misunderstanding on which the Charter had been based.This proposal placed the boundary near 39 36', creating a wide strip of disputed territory.Because the fortieth parallel lay north of the city of Philadelphia, Maryland pressed its claim most seriously in the sparsely inhabited lands west of the Susquehanna River.
