Mabel Island 



is between 3 and 4 miles south- 

 west of Bruce Island. Its aspect, 

 as seen from Cape Flora, is 

 represented in fig. 8. The ice- 

 covering does not rise much above 

 the level of the basaltic plateau. 

 The surface is uneven, and, where- 

 ever the rocks do not obstruct its 

 downward flow, the ice descends 

 to sea-level, ending in cliffs often 

 60 feet or more in height. 



The rocks are of the usual 

 basalt, arranged in five or six 

 tiers and rising to a height of 

 about 750 feet. Sometimes they 

 form cirques or corries, and at 

 others jut out from the ice-slope 

 in the customary way. A talus 

 is found below the rocks, and 

 raised beaches occur at heights 

 of from 22 to 80 feet. In one 

 place on the south-eastern side 

 a -well-marked beach was seen 

 at a height of 300 feet, and 

 traces of another at 410 feet 

 above sea-level. I did not see 

 the sedimentary rocks from which 

 the belemnites and other fossils 

 brought home by Messrs. Leigh 

 Smith and Grant were derived ; 

 but this is not remarkable, because 

 the surface was much covered with 

 snow when I visited the island in 

 April and May. 



Bell Island 



is separated from Mabel Island 

 by a narrow channel named Eira 

 Harbour.^ It is mostly composed 

 of terraces of raised beach, 

 covered with rounded stones and 

 pebbles of basalt and quartzite. 



^ Across Eira Harbour, between the 

 southern extremity of Mabel Island and 

 the opposite point on Bell Island, runs 

 a shoal which almost reaches sea-level. 

 It appears to be made up of the same 

 rounded stones as those which form the 

 raised beaches on Mabel and Bell Islands.
