PLATE XLL MOUNT EREBUS. 



FIG. 1 (Map B). From a photograph by R. W. SKELTON (Sk. 62, j- plate), 

 March 9, 1902 ; showing Mount Erebus from the S. side of Ross Island. 



FIG. 2 (Map B). From a photograph by L. C. BERNACCHI (Be. 37, {-plate), 

 March 1, 1902 ; showing Mount Erebus from Harbour Heights, looking 



to N.-N.-E. 



FIG. 3 (Map B). From a photograph by E. H. SHACKLETON (Sh. 174, ^-plate), 

 Oct. 1902; gives a somewhat similar view of Mount Erebus, taken from 

 the top of Crater Hill, just above Winter-quarters Bay ; Castle Rock 

 appears in the middle distance. 



Note in Fig. 1 that a puff of white vapour is making its way from the crater. 

 Note also in Figs. 2 and 3 how the wide and symmetrical shoulders of the older 

 crater enclose the more recent cone which has been formed within it. 



The glacier-covering of this mountain on the S. and S.-W. sides is so complete 

 that hardly anywhere can bare rock be seen. 



In Fig. 2 a small low rocky islet, which is known as Tortoise Rock, from its 

 shape, occupies almost the mathematical centre of the picture.
