Next day the light was very bad and the wind fifty miles per hour. Observations were therefore made inside the tent. Webb, Hurley and the instrument occupied all available space, while I spent three hours digging a shaft eight feet deep in the snow, taking temperatures every foot. It appeared that the mean annual temperature of the snow was approximately -16 degrees F.
The dip was 88 degrees 54'; certainly rather too large a rise from 88 degrees 20' of twenty miles back. The declination had actually changed about 80 degrees in the last ten miles. This one-hundred-mile station was badly disturbed. From the evidence, it is possible that a subsidiary "pole" or area of almost vertical dip may exist close by this spot to the west or south-west.
Going straight up wind into a "blow" which varied from forty to fifty miles per hour, we were able to make eight miles after the previous day's rest. At lunch a hole was dug five feet square and two feet deep. It served three purposes. First, it gave a good shelter for a longitude observation; secondly, with the mast, yard and floor-cloth we converted it into a shelter snug enough to house the primus and to lunch comfortably; and thirdly, a mound was left as a back-mark which was picked up on the return journey.
By experience we found that a warm lunch and a rest enabled one to "peg" along a good deal farther than would otherwise be possible.
The "scenery" in the afternoon became if possible more desolate—very few new sastrugi, the surface appearing generally old and pitted. In some places it was rotten and blown away, disclosing coarse granulated substrata. At the top of one ridge the snow merged into neve split into small crevasses, nine inches wide and four or five yards apart. The camp was pitched, here, at 11 P.M. The latitude was 68 degrees 32' S., and we saw the midnight sun for the first time that summer, about one-quarter of its rim remaining above the horizon.
A full hurricane came up and kept between fifty and sixty miles per hour all day on the 30th. Before moving off, Webb found that the magnetic needle had "waltzed" back 60 degrees since the one-hundred-mile camp, now pointing 80 degrees east of south. Still, to allow the needle to makeup its mind, we steered into the wind at 2 P.M., losing the neve and meeting very rough country. By 6 P.M., with four miles to our credit, we were nearly played out. It was being discussed whether we should go on when the discovery was made that the theodolite legs were missing; probably having slipped out in one of the numerous capsizes of the sledge.
The solemn rites of "shut-eye" determined that Webb was to stay and make camp while Hurley and I retraced our steps. It was no easy matter to follow the trail, for on hard snow the sledge runners leave no mark, and we had to watch for the holes of the crampon-spikes. About two and a half miles back, the legs were found, and there only remained a hard "plug" against the wind to camp and hoosh.
While we were lying half-toggled into the sleeping-bags, writing our diaries, Hurley spent some time alternately imprecating the wind and invoking it for a calm next day. As he said, once behind a break-wind one could safely defy it, but on the march one is much more humble.
Whether it was in honour of Queen Alexandra's birthday, or whether Hurley's pious efforts of the evening before had taken effect, December 1 turned out a good day. By noon, the wind had dropped sufficiently for us to hoist the Jack and Commonwealth Ensign for the occasion.
After four miles of battling, there came into sight a distinct ridge, ten miles to the west and south—quite the most definitely rising ground observed since leaving the coast. In one place was a patch of immense crevasses, easily visible to the naked eye; in another, due south, were black shadows, and towards these the course was pointed.
