the "house-roof" formations near Saglek, and the narrow ser- 

 rate ridges of the Kiglapait near Manvers, and of some of 

 the ranges at Nachvak. 



Particularly marked is the contrast betwen the lower 

 surfaces of the south and the bolder, steeper, often more in- 

 tricately-sculptured ridges that begin north of Port Man- 

 vers. In the more southerly portions the coastline, as we 

 have seen, is broken into numerous irregular bays and in- 

 dentations, its waters crowded with hosts of small islands, and 

 its mainland rising into a continuous series of low^ elevations. 

 These hills may slope up gradually from the water or present 

 precipitous cliffs rising with sharp directness. In one or two 

 rare localities sandy beaches take their place, smooth and 

 hard, usually of small extent but attaining a considerable mag- 

 nitude at the Strand near Cape Porcupine. The slopes are 

 usually humpy with irregular projecting naked rocks in the 

 midst of vegetation ; but occasionally they take on special 

 shapes, such as the frequently-occurring raised beaches, 

 sometimes of small pebbles and rarely of large boulders, that 

 give evidence of their former submergence ; smooth, grassy 

 ascents, that are seldom seen ; or the roches moutonnees 

 forms, so prominent at Pomiadluk. The seaward face is 

 varied not only by these rough irregularities of structure and 

 shaping, but also by the different coloring and behavior of its 

 different materials. The grayish gneiss, which is the main 

 rock of the country, softens into comparatively rounded con- 

 tours ; but the dykes of black volcanic trap that cut it every- 

 where are harder to the air and softer to the sea, and they 

 break into more angular and wild-seeming fragments. 

 Where other rocks occur, such as slates, sandstones, and con- 

 glomerates, the variety in coloring and contour becomes
