and gneiss-granites which fact causes an abrupt and striking change in 

 the development of the strandfiat, as has been pointerl out by Hoel. 

 In this granite region the emerged strandfiat is, as a rule, hardly more 

 than a hundred or a few hundred metres broad. On both sides of Ham- 

 l)urg Bav, south of Magdalena Bay, it is 300 to 400 metres broad. Tn 

 some places in this region the emerged strandfiat is missing altogether. 

 The submerged strandfiat also seems to be poorly developed along a great 

 part of this coast, but there are too few soundings to trace its extent. 



On Danes Island and Amsterdam Island, built up of granite, the 

 emerged strandfiat is also narrow or missing. P^ig. 145 shows the strand- 

 flat along the north-east coast of Danes Island. It is in this region less 

 even than in the region of the Hecla Hook rocks to the south, and it is 

 more like the strandfiat in the granite regions of Norway. 



The low level plain, the Hollaender Ness, on the east side of Amster- 

 dam Island (Fig. 146) is chiefly formed of loose material (sand and 

 moraine material), but in its inner part near the foot of the mountain 

 there is obviously rocky ground near the surface (Fig. 147). 



Off these islands and also north of the islands X'ogelsang, Cloven 

 Cliff, and Norway Islands, there is a submerged strandfiat with skerries 

 and rocks and with depths of less than 30 metres. Its extent cannot be 

 traced, as the soundings are too few. North of Norwav Islands it seems
