deposit of clay, while in front, about thirty feet lower, is a 
deposit of fine sand. The rounded stones in this old beach are

origin, probable Quarternary. At this time the sea must have 
covered the whole of the Cornwallis and Annapolis Valley. 
There is also evidence that the land must have been at one 
time considerably higher than at present, for on the northern 
side of Long Island, about thirty feet below high water mark, 
are the remains of buried trees, 7m situ, the stumps, roots, and 
even trunks well preserved. This would call for a subsidence of 
40 to 50 feet.
