The borough of Mercer stands as a central hub in this pre-war survey, where the Lake Shore and Michigan Southern RR and the Pennsylvania RR converge. To the east, Grove City exhibits a dense grid of development along the Bessemer and Lake Erie RR, serving as a significant industrial anchor for the region. The landscape is a mix of agricultural tracts and early industrial activity, notably marked by the Number Five Mine and an Oil Pumping Sta near Millburn School.
