Sketch showing the Portion of the Discovery in the Antarctic Reuiuns. 



Shackleton, who became ill, returned 

 on the Morning, and is about to pub- 

 lish an account of the expedition. An- 

 other expedition headed by Lieutenants 

 Armitage and Skelton went westward, 

 climbing a glacier 9,000 feet high, the 

 ice extending far inland. Other geo-

 discovery that Mts. Erebus and Terror 

 are on a small island and that Mae- 

 Murdo Bay is not a bay but a strait.

 the proposition is one which will doubt- 

 less attract popular attention, it will 

 be well to place the exact facts before 

 our readers.
