West Enp or LAKE ERIE. 
Between Buffalo, at the east end of this lake, and the Islands, the rocks near 
the water level are generally too soft to retain the ancient ice-markings. On the 
lime rock at Buffalo there are numerous and distinct etchings that bear from south, 
25° west to south 30° west, and run under water. Their bearings are nearly parallel 
with the axis of the trough of the Lake. At the mouth of Detroit River, near Gibraltar, 
the limestone beds are grooved and polished, and the bearings are also south 30° 
west. The islands and the limestone shores to the south and west are everywhere 
scored and grooved in the same way; but the bearing is generally more to tne west,
