On this bearing there is visible a small central crater at the summit of 

 Mount Erebus, with lips tilted to the N.-W. This appearance was not seen from 

 any other point. 



Ross Island gives a footing for at least three Ade'lie Penguin rookeries in the 

 summer months ; of these the largest is at Cape Crozier, the second is on Cape 

 Bird, and the third, a small one, on Cape Royds. 



PLATE CXXXVIL ROSS ISLAND FROM THE S.-W. 



From a sketch made on board ship in M'Murdo Sound ; Feb. 8, 1902, 5 P.M. 

 (Map B.) 



At the foot of Mount Erebus are seen two of the Dellbridge Islands, and to 

 the right of them a conspicuous cliff and projecting rock on the coast known as 

 "The Jetty." 



Mount Terror is here shown without any sign of cloud or vapour. 



From this point to Cape Armitage on the right is a broad-side view of the 

 long and narrow promontory, at the southern end of which was " Winter-quarters 

 Bay." 



Castle Rock, 1310 feet above sea-level, the plug or core of a volcanic cone 

 since gone, is the most conspicuous landmark on this tongue of land, and to the 

 right of it are the slopes upon which our companion Vince met with his fatal 

 accident. 



The summit of Crater Hill, 1000 feet above sea-level, was used as a station for 

 temperature observations throughout the winter months.

FROM TURTLE ROCK. 



From a sketch made looking N.-E. from Turtle Rock; Sept. 10, 1903. 

 (Map B.) 



Turtle Rock lies about half a mile off the west coast of Winter-quarters 

 Peninsula, and four and a half miles from Hut Point. 



Surrounded by a tide-crack, and with ingress to and egress from the water 

 made easy by movement in the ice around it, the island was a favourite haunt of 

 Weddell Seals, which frequented it especially in the early summer when about to 

 give birth to their young.
