a fragment of the granitic ridge, was at no very distant date 

 joined to the mainland at King's Point, from which it is now 

 separated by a sea channel of about half a mile in width. 

 According to the Admiralty Directory the island is 132 ft. 

 in height, which is a little higher than the highest point of 

 the moraine at King's Point. The island has a remarkably 

 even and rounded contour, suggestive of having been sub- 

 jected to glacial erosion (plate xi.). 



West Island appears to stand in a similar relation to the 

 moraine of King's Point as Rosetta Head does to the 

 moraine of Encounter Bay, as already explained. In the case 

 of King's Point, the sea-channel and adjacent land represent 

 the rock-trough (or "over-deepening") cut out by the glacier 

 on the down-flow side, and there is also present an undulating 

 floor of schists with morainic debris in protected situations. 

 The schists (which are mostly fine-grained mica-schists similar 

 to those at the back of Rosetta Head) are relatively soft, and 

 owe their preservation, as a headland, to the protection which 

 West Island affords. A similar process of cutting into the 

 schists is in evidence at the back of Rosetta Head : an isthmus 

 is being formed by encroachments of the sea behind the 

 granite ridge, and, in time, Rosetta Head will be disconnected 

 from the mainland in the same way as West Island has 

 become. It is fortunate that King's Point has been pre- 

 served from the levelling action of the waves, as it exhibits, 

 notwithstanding its great geological age, an example of a 

 moraine which might be regarded as typical of those laid down 

 by existing glaciers. 



In plate ii. a sketch-section of the moraine is given, so far 

 as it is seen within the limits of King's Point. The schists occur 

 as strong reefs on the beach, and show an elevation at the 

 head of the Point of about 20 or 30 ft. above sea-level. 

 The original outline of these old rocks was probably in the 

 form of a dome, as they have a slope on the landward side 

 and disappear under the moraine, about one-third distance 

 between the Point and the normal line of cliffs. The pro- 

 montory rises gradually from the point until, when in a 

 line with the usual contour of the sea-cliffs, it reaches a height 

 of 100 ft. With the exception of a part of the headland, as 

 just described, the whole of the promontory consists of 

 morainic material. 



The moraine, whilst in remarkable preservation as a 

 whole, has been cut into by the weather. The upper surface 

 has been lowered and its sides have been seamed by run- 

 ning waters. The small gullies thus formed give interesting 

 sections of the beds, and the removal of the finer material
