Abstract

The region about Boston forms a basin. Standing on the reservoir at College Hill one looks north, west and south upon lines of hills surrounding Boston and the thickly populated adjoining country. In the relation of the rocks underlying the drifts this region also forms a basin. The distant hills are of hornblende granite extending from near Marblehead southwest to near south Natick, thence east toward Quincy. Close to this granite area are other igneous rocks, and within the basin, conglomerate and slate so related and concealed by drift as to present many difficult problems.
