As the land went down the sea advanced both from the Atlantic side and up the sinking valley of the Susquehanna river, until it came to a standstill somewhere near the present location of the Baltimore and Ohio Eailroad. When the sea had thus encroached on the land the topography of Cecil county was very different from what it is to-day. The accompanying diagram (Fig. 1) gives an.
