Lunch. Height 10,540. T. -15° 8′. It was heavy pulling from the beginning to-day, but for the first two and a half hours we could keep the sledge moving; then the sun came out (it had been overcast and snowing with light south-easterly breeze) and the rest of the forenoon was agonising. I never had such pulling; all the time the sledge rasps and creaks. We have covered 6 miles, but at fearful cost to ourselves.
Night camp 63. Height 10,530. Temp. -16.3°. Minimum -25.8°. Another hard grind in the afternoon and five miles added. About 74 miles from the Pole—can we keep this up for seven days? It takes it out of us like anything. None of us ever had such hard work before. Cloud has been coming and going overhead all day, drifting from the S.E., but continually altering shape. Snow crystals falling all the time; a very light S. breeze at start soon dying away. The sun so bright and warm to-night that it is almost impossible to imagine a minus temperature. The snow seems to get softer as we advance; the sastrugi, though sometimes high and undercut, are not hard—no crusts, except yesterday the surface subsided once, as on the Barrier. It seems pretty certain there is no steady wind here. Our chance still holds good if we can put the work in, but it’s a terribly trying time.
