East of the Tasman glacier, brings the ice masses down from Mount 
Darwin and Mount M alto Brum The river streaming from it issues 
from a glacial-cave on the extreme East -side of the glacier. The 
Hooker glacier comes in two branches from the southern foot of 
Mount Cook; whilst the ice masses of the Mueller glacier descend 
from Mount Sefton and the Moorhousc range. 1 Near the head of 
this glacier is a pass over a wall, formed of nearly perpendicular 
rocks about 100 feet above the glacier, which would bring us upon 
the Selwyn glacier, forming one of the sources of the River Hob- 
son, falling into Lake Ohau (or Oliou). 2 About a quarter of a mile 
down the Dobson river valley another glacier, of a very peculiar 
formation, comes down tlie principal peak of the Naumann range, 
which runs from the Moorhouse range between the two main branches 
of the Hopkins river to their junction. Owing to the great steep- 
ness of the mountain sides, a large portion of the ice is pushed 
before it can melt, at many spots over the perpendicular ledges, 
and falling down with a tremendous crash, is again cemented to- 
gether to expand to a new glacier; at the same time a narrow chan- 
nel between the upper and lower glaciers brings down the remains 
of the upper ice masses, which have escaped being thrown over. 
Dr. Haast named this glacier the Hourglass glacier, from its pecu- 
liar form. The elevation of its terminal face is 3816 feet. 
What an impassable wall of ice and rock the Southern Alps 
proper present, is still more apparent at the West Coast, whore also 
glaciers scarcely less inferior in size to their eastern neighbours 
descend towards the West Coast plains. It is there whore the exi- 
stence of a glacier is stated, the terminal face of which lies only 
705 feet above the sea, with a rich and varied vegetation close to

2 According to Mr. Thomson lake Ohau has an elevation of 1498 feet, measur- 
ing 12 miles in length and 24/ 2 miles in breadth. The other lakes on the eastern 
foot of the Southern Alps are Hawea, measuring 12 miles in length, and 2 in breadth, 
having an elevation of about 1000 feet above the sea; Wanaka, 1036 feet above the 
sea, 14 miles long, 4 miles broad, Taieri, having an elevation of 906 feet, and 
measuring l ] / 2 miles in length and one mile in breadth; lake Wakatipu on the upper 
branches of the Clutha, finally North and South Anau at the sources of the Waiau 
river, which empties into Foveaux Strait.
