DALY : GEOLOGY OF THE NORTHEAST COAST OF LABRADOR. 253 



Bauld, Newfoundland. Wave-built terraces were found at six, twenty- 

 two, thirty-five, and seventy feet above high-water on the hills over- 

 looking the harbor itself. Others measured six, twenty-two, thirty-five 

 and one hundred and twenty feet in Mauve (Noddy) Bay. A third 

 set on Kirpon Island measured six, twenty-two, thirty-five, seventy, 

 and one hundred and twenty feet, and were particularly well exposed 

 in Grand Galets Bay. The one hundred and twenty-foot beach-terraces 

 match well with the very strong rock-benches on the headlands com- 

 posed of the relatively soft slates about the entrance to Mauve Bay. 

 At Grand Galets, where the indentation is deep both vertically and 

 horizontally, terraces at all the levels may be seen. We hoped to find 

 similar correspondences among the beaches across the Straits, but 

 failed to do so. In Labrador nothing comparable to the beautiful 

 system underlying the occurrence of the warped ancient shore-lines 

 of the Great Lakes could be determined. It is impossible to deny 

 that the uplift has been on the Labrador coast, as so often illustrated 

 elsewhere, spasmodic, but it does not follow that this intermittent 

 character will be reflected in the raised beaches of the present day. 

 In most cases an ancient beach has been composed and located where 

 it is because of special local conditions of formation and not because 

 there occurred a halt in the uplifting process. Deposition takes place 

 wherever the required protection against under-tow and shore-ice in 

 the presence of appropriate off-shore depth, is afforded. (Plate 10.) 

 If the hardness of the rocks, the off-shore depth, or the fetch and direc- 

 tion of the more effective waves were to change at a given point, the 

 balance of conditions leading to beach-formation would be destroyed. 

 Thus a beach growing under the former circumstances, might grow 

 faster under the new; or, on the other hand, be demolished, its debris 

 forming a new beach elsewhere or helping to raise the sea-floor whither 

 it was dragged. Probably no single factor in producing such changes 

 on the Labrador coast has been so important as vertical movements of 

 the land. 



Not only, thus, will those beaches that were really formed during 

 halts in the elevatory process, be difficult to distinguish from those 

 developed in protected bays as uplift takes place ; the record of halts 

 will be further masked by the appearance of beach-like deposits laid 

 down on steep-to shores in several fathoms of water. An interesting 

 example has been described by Packard as "a truly noble beach." 

 It occurs on the south side of Sloop Harbor. It is about two hundred 

 yards long and roughly graded from the one hundred and fifty -five-foot
