W. II Twenhofel — Physiography of Newfoundland. 23 



Above the terraces the Cambrian sandstones and limestones 

 rise to about one level, presenting a flat-topped upper surface 

 which truncates the structure. 



A trip was made westward along the coast to Brador Bay, 

 the site of the ancient French settlement of New Brest, to 

 examine the contact between the Cambrian and the gneiss. It 

 was not found, having been completely eroded out by a river

which follows it back into the country, forming a lowland 

 between the Cambrian strata and the crystallines. Inquiry 

 along the coast elicited the information that this depression 

 exists almost everywhere between the Cambrian and the 

 gneiss. If this be correct, then the Cambrian strata form a 

 cuesta and the line of contact with the Laurentians an inner 

 lowland. 



Conclusions. 



(1) The physiography of Newfoundland owes most of its 

 detail to the structure and texture of the rock which have local- 

 ized erosion along the zones of the softer sediments and frac-
