THE HEART OF THE ANTARCTIC 



Just inland to the north of the Drygalski Ice Barrier 

 Tongue is a fine bay, Terra Nova Bay, inland from which, 

 near its northern end, rises the majestic Mount Nansen. 

 This is a flat-topped mountain, obviously capped by 

 sedimentary rocks, and as a matter of fact, it has shed 

 lumps of limestone and sandstone into the moraines 

 beneath it. 



Still further north the beautifully symmetrical volcanic 

 cone of Mount Melbourne attains a height of 8337 ft. 

 The volcanic rocks with which it is associated trend sharply 

 to the south-west, terminating in the high rugged cliffs 

 of Cape Washington. 



To the north-east of Mount Melbourne is the deep 

 indentation known as Wood Bay, and thence the coast 

 bends abruptly to the east. It would seem indeed as 

 though Mount Melbourne is probably situated on some 

 east and west line of earth fractures, like Mounts Terror 

 and Terra Nova. The coast-line then trends nearly north 

 again, forming the west boundary of Lady Newnes Bay. 

 Then it trends once more east to Cape Jones, an extinct 

 volcano. Just off Cape Jones lies the large volcanic 

 island, Coulman Island. From here the coast again trends 

 chiefly northerlj^ to Cape Adare. Volcanic rocks are ex- 

 tensively developed at this cape, but the ranges inland 

 are formed of older rocks, such as granite, gneiss, schist, 

 slate, &c., apparently still capped by the " Beacon sand- 

 stone " formation. The island known as Possession 

 Island — also volcanic — hes to the south-south-east of 

 Cape Adare. This long cape, where the Southern Cross 

 expedition, under Borchgrevink, wintered, forms the 

 north-east side of Robertson's Bay. From this bay the 

 coast trends at first north-westwards for about 120 miles 

 to Cape North. Near here, some hills, a little distance 

 back from the coast, give one a strong impression of their 

 being of volcanic origin, though it is possible that they
