I9xi] CROZIER PARTY'S EXPERIMENTS 323 
the heat gradually rises until the oil issues from B in 
a vaporised condition, when, of course, the heat given 
off by the stove is intense. 
This stove was got going this morning in five minutes 
in the outer temperature with the blubber hard frozen. 
It will make a great difference to the Crozier Party if they 
can manage to build a hut, and the experience gained will 
be everything for the Western Party in the summer. 
With a satisfactory blubber stove it would never be 
necessary to carry fuel on a coast journey, and we shall 
deserve well of posterity if wc can perfect one. 
The Crozier journey is to be made to serve a good 
many trial ends. As I have already mentioned, each 
man is to go on a different food scale, with a view 
to determining the desirable proportion of fats and 
carbo-hydrates. Wilson is also to try the effect 
of a double wind-proof suit instead of extra woollen 
clothing. 
If two suits of wind-proof will keep one as warm in 
the spring as a single suit docs in the summer, it is evident 
that we can face the summit of Victoria Land with a very 
slight increase of weight. 
I think the new crampons, which will also be tried on 
this journey, are going to be a great success. We have 
returned to the last Discovery type with improvements; 
the magnalium sole plates of our own crampons are re- 
tained but shod with |-inch steel spikes ; these plates 
are riveted through canvas to an inner leather sole, and 
the canvas is brought up on all sides to form a covering 
to the ' finnesko ' over which it is laced — they are less
