PLATE XLIL MOUNT EREBUS FROM THE S.-S.-W. 



From a photograph by R. W. SKELTON (Sk. 279, ^-plate), Oct. 6, 1903 ; looking 

 N.-N.-E. from the sea-ice off' Harbour Heights. (Map B.) 



From this point the mountain appears with a very regular outline, and shows 

 the small cone and crater which is at present active, situated within the former 

 crater, whose wider shoulders stand out on either side. No suggestion of the still 

 more extensive crater lip, visible on the N.-E. slope, is to be seen from here. 

 Many old overflows of lava can be seen as rocky ridges running down the side 

 from the lips of the uppermost craters. 



The picture gives a very good idea of the sea-ice surface of M'Murdo Sound 

 throughout the two years of the ' Discovery's ' stay there.
