234 CRUISE OF THE NEPTUNE 



bay. At Erik harbour, on the south side of the mouth of Ponds 

 inlet, there is evidence that the glacier which now terminates 

 at the head of the harbour once extended five miles farther sea- 

 ward, and filled the valley to a height of 400 feet above the 

 present level of the sea. Above that height the rocky walls of 

 the harbour are not glaciated, and are covered by slopes of dis- 

 integrated rock. Passing north of Lancaster sound to the south 

 of North Devon, there is little evidence to show that the glacia- 

 tion was ever much more severe than at present. At Cuming 

 creek, a narrow fiord cut some twelve miles into the limestone 

 cliffs, there is evidence that a glacier once covered its bottom, 

 and rose some two or three hundred feet above the present level 

 of the sea; but it was purely local, and the limestone cliffs 

 everywhere show that they have been long subjected to subaerial 

 denudation, and that the broken rock covering their sides has 

 never been displaced by ice. 



Very little time was given to the study of glaciation at Cape 

 Sabine, and the only evidence to show that it was more intense 

 formerly was a low moraine in rear of Peary's house at Payer 

 harbour. Schei, who devoted considerable attention to the gla- 

 ciation of Ellesmere, is of the opinion that the ice covering 

 never greatly exceeded its present limits, if it did so at all. 



MARINE TERRACES. 



Marine terraces are found along the coasts of the northern 

 mainland and islands wherever the conditions are suitable. 

 Fronting the highlands about Wager inlet and Repulse bay, on 

 the western side of Hudson bay, terraces are found cut into the 

 drift deposits up to elevations varying from 500 to 700 feet. 

 The highest terrace seen by Dr. Bell on the north side of Hud- 

 son strait had an elevation of 528 feet above the present sea- 

 level. At Cape Wolstenholme, on the south side of the western 

 entrance to Hudson strait the terraces rise to 800 feet above the
