[poole] PRE-GLACIAL EIVER OF GULF OF ST. LAWRENCE 147 



trcted by the comparative narrowness of the sea erosion at the head of 

 the gulf had not proceeded so far, and so it occurs that Bay Verte and 

 Anxet Sound still retain, resting on the older series;, outliers of the 

 Prince Edward Island or gulf deposit. 



Similar and contemporary conditions seem also to have prevailed 

 outside Cabot Strait, on the eastern side of Cape North, where a deep 

 estuary received the streams from St. Ann\ the great Bras d'Or and 

 Sydney harbor. More exposed than the gulf to the action of ocean 

 currents, there has been more obliteration of the original features ; still 

 there is no difficulty in developing here also, a system of drainage for 

 the ocean floor, in times preglacial, when the region was greatly ele- 

 vated, and when the many rivers that now discharge directly into the 

 sea, were all tributaries to that majestic stream, the ancient Eiver St. 

 Lawrence.
