i9u] START OF THE CROZIER PARTY 333 
discussion on the point and no very satisfactory solution 
offered. Cannot help thinking that there is something 
in the thought that the glacier may have been weighted 
down with rubble which finally disengaged itself and 
allowed the ice to rise. Such speculations are interesting. 
Preparations for the start of the Crozier Party are now 
completed, and the people will have to drag 253 lbs. per 
man — a big weight. 
Day has made an excellent little blubber lamp for 
lighting; it has an annular wick and talc chimney; a 
small circular plate over the wick conducts the heat down 
and raises the temperature of combustion, so that the 
result is a clear white flame. 
We are certainly within measurable distance of using 
blubber in the most effective way for both heating and 
lighting, and this is an advance which is of very high 
importance to the future of Antarctic Exploration. 
Tuesday^ June 27. — The Crozier Party departed this 
morning in good spirits — their heavy load was distributed 
on two 9-feet sledges. Ponting photographed them by 
flashlight and attempted to get a cinematograph picture 
bv means of a flash candle. But when the candle was 
ignited it was evident that the light would not be sufficient 
for the purpose and there was not much surprise when the 
film proved a failure. The three travellers found they 
could pull their load fairly easily on the sea ice when the 
rest of us stood aside for the trial. I'm afraid they will 
find much more difficulty on the Barrier, but there was 
nothing now to prevent them starting, and off they went. 
With helping contingent I went round the Cape.
