deposit of clay, while in front, about thirty feet lower, is a 

 deposit of fine sand. The rounded stones in this old beach are 

 mainly trap, so that the formation is of comparatively recent 

 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, in situ, the stumps, roots, and 

 even trunks well preserved. This would call for a subsidence of 

 40 to 50 feet.
