always preceded by an overcast sky in accordance with 
Simpson's theory.

ham's photographs, and many of them were quite beautiful. 
Ponting tells me that Debenham knows quite a lot about 
photography and goes to work in quite the right way. 
The lecture being a precis of Taylor's report there is

was startling to realise the very different extent to which 
tributary glaciers have carved the channels in which 
they lie. The Canadian Glacier lies dead, but at ' grade '

hangs at an angle of 25 0 , with practically no channel. 
Mention was made of the difference of water found in 
Lake Bonney by me in December 1903 and the Western 
Party in February 191 1. It seems certain that water

sponges on the Koettlitz Glacier. Heaps of large sponges
