330 THE VOYAGE OF THE 'DISCOVERY [Appx. 



Moimt Melbourne is conical, but has a small crater, probably a 

 quarter of a mile in diameter, at its summit. It is situated on the 

 south side of Wood Bay, and rises directly out of the sea on two 

 sides. The mountains to the west of it recede from the coast, 

 so that it stands in icy isolation guarding the entrance to the 

 bay. Basalt was obtained near the mountain by the ' Southern 

 Cross' Expedition, and pumice pebbles, which must have come 

 from its flanks, have since been found on a small floe floating in 

 Wood Bay. 



Mount Morni7ig is about 5,000 feet high, and is situated near 

 the foot of the Royal Society Range. It is a low dome which 

 covers a comparatively large area, and lava-streams are still 

 apparent on its sides ; but as no specimens have been collected, 

 nothing further need be said. 



Mount Discovery is a most striking mountain of accumulation, 

 as it has the shape of a pear standing on its broader end, and the 

 curves which meet at its summit descend symmetrically on all 

 sides almost to sea level. It appears to be composed of basalt 

 similar to that of the Ross Island Group, and parasitic vents are 

 not conspicuous. The Minna Bluff, a long narrow peninsula pro- 

 jecting from it towards the south-east, is also composed of basalt 

 similar to that from Winter Quarters. 



King Edward VII. Land. 



King Edward VII. Land^ between the latitudes of 76° and 

 78° S. and the longitudes of 160 and 150° W., does not show great 

 relief, but a bold headland stands out conspicuously before the 

 main mass. As fragments of plutonic and gneissic rocks were 

 obtained from an iceberg which had grounded near here, it is 

 possible that the main mass is made up partly of rocks of these 

 types. 



The Continental Range. 



South Victoria Land, as far as we know at present, consists of 

 a great range of mountains, stretching in a north-and- south direc- 

 tion for at least 800 miles, and apparently it is the eastern edge of 

 a vast plateau. The only direct evidence of the existence of this 

 plateau was obtained between latitudes yj'^ and 78'' S., where 

 Captain Scott travelled 200 miles westward at a uniform height 

 of 9,000 feet above sea level.
