follows the sacrifice to comfort is negligible. Certainly we could not have increased our mileage by making such a sacrifice.

But beyond this it may be argued that we have an unnecessary amount of food: 32 oz. per day per man is our allowance. I well remember the great strait of hunger to which we were reduced in 1903 after four or five weeks on 26 oz., and am perfectly confident that we were steadily losing stamina at that time. Let it be supposed that 4 oz. per day per man might conceivably be saved. We have then 3 lbs. a day saved in the camp, or 63 lbs. in the three weeks, or ¹⁄₁₀₀th part of our present loads.

The smallness of the fractions on which the comfort and physical well-being of the men depend is due to the fact of travelling with animals whose needs are proportionately so much greater than those of the men. It follows that it must be sound policy to keep the men of a sledge party keyed up to a high pitch of well-fed physical condition as long as they have animals to drag their loads. The time for short rations, long marches and carefullest scrutiny of detail comes when the men are dependent on their own traction efforts.

6 p.m.—It has been blowing from the S.W., but the wind is dying away—the sky is overcast—I write after 9 hours' sleep, the others still peacefully slumbering. Work with animals means long intervals of rest which are not altogether easily occupied. With our present routine the dogs remain behind for an hour or more, trying to hit off their arrival in the new camp soon after the ponies have been picketed.
