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 we 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 does 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 retained but shod with ½-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
