Abstract

Numerous buried channels filled with drift occur over Ohio and the neighbouring states forming the St. Lawrence basin. Some of these penetrate the water-parting, and formed, according to Prof. Newberry, waste weirs through which the lake waters of the St. Lawrence basin escaped into the valley of the Mississippi, as the land rose and the sea retired from that valley.
