804 Goldtkwait— Twenty-Foot Terrace and 



(laspe Peninsula, it is quite probable that future exploration 

 of that region, and of the adjoining coast of New Brunswick, 



will show that the extent of the strand southward is as great 

 as its extent in the Saint Lawrence estuary; for in the Saint 

 Lawrence it maintains an approximately uniform altitude for 

 more than 200 miles, along a line which runs almost directly 

 up the incline of the Chain plain geoid surface. Although at 

 Matane the altitude of the Champlain beach is 174 feet, and 

 near Quebec, 032 feet, the altitude of this low terrace is prac- 

 tically the same at both places, and at all intermediate points 

 ■where measurements have been made. This is shown in the 

 table below.* 



L'Ange Gardien. 14-16 feet 



Trois Pistoles 14-19 " 



Saint Simon, beach at 17 feet > 



Bic 19-21 feet 



Sacre Coeur 20-23 " 



Rimouski 22 " 



Little Metis beach at 1 9 feet 



Mac Nlder's - 20-22 feet 



Riviere Blanche 15-17 " 



A strongly marked terrace at about the height of this one 

 has been reported at several distant places by other observers. 

 In describing the elevated marine terraces of the island of 

 Anticosti, Mr. W. H. Twenhofel statesf that the lowest ter- 

 race, which stands from 8 to 15 feet above high tide mark, 

 nearly surrounds the island. Its average width is about a 

 quarter of a mile ; and its maximum width, over two miles. 

 Prof. R. A. Daly, in his description of the beaches of the 

 Labrador coast, mentions an exceptionally strong shoreline not 

 far above the sea, at West Bay, Hamilton Inlet. According 

 to his account, "there was a comparatively long halt in the 

 process of elevation when the sea level was about thirty-five 

 feet above its present position ; at that time there was devel- 

 oped a distinct bench. "J Although Hamilton Inlet is about 

 600 miles northeast of Matane, the occurrence of a particu- 

 larly strong shore terrace at this low level is rather suggestive 



*The measurement, unless otherwise radicated, is the altitude of a wave- 

 cut terrace at the foot of a bluff. Where a beach was measured, the crest 

 of it was taken. The datum plane is local high tide mark, as registered by 

 the line of flotsam on the beach. This, at Sacre Coeur, wa3 found to be 

 four feet above mean tide, and three feet below the mark of storm waves at 

 high tide. The high tide surface is of course somewhat irregular ; and this 

 may account for much of the discrepancy in the altitudes here given.
