I remember waking up early one morning to find the Hut unusually cold. On rising, I discovered Hurley also awake, busy lighting the fire which had died out. There was no sign of Correll, the night-watchman, and we found that the last entry in the log-book had been made several hours previously. Hurley dressed in full burberrys and went out to make a search, in which he was soon successful.
It appeared that Correll, running short of coal during the early morning hours, had gone out to procure some from the stack. While he was returning to the entrance, the wind rolled him over a few times, causing him to lose his bearings. It was blowing a hurricane, the temperature was -70 F., and the drift-snow was so thick as to be wall-like in opacity. He abandoned his load of coal, and, after searching about fruitlessly for some time in the darkness, he decided to wait for dawn. Hurley found him about twenty yards from the back of the Hut.
The suppression of outdoor occupations reacted in an outburst of indoor work. The smaller room had been well fitted up as a workshop, and all kinds of schemes were in progress for adapting our sledging-gear and instruments to the severe conditions. Correll worked long hours to keep up with the demands made upon him. Nobody was idle during the day, for, when there was nothing else to be done, there always remained the manufacture and alteration of garments and crampons.
As soon as the wind abated to a reasonable velocity, there was a rush to the outside jobs. Lulls would come unexpectedly, activity inside ceased, and the Hut, as seen by a spectator, resembled an ants' nest upon which a strange foot had trodden: eighteen men swarming through the manhole in rapid succession, hurrying hither and thither.
The neighbouring sea still remained free from an ice-crust. This, of course, did not mean that freezing was not going on continuously. On the contrary, the chilling was no doubt accelerated, but the bulk of the ice was carried off to the north as fast as it was formed. Quantities, however, remained as ground-ice, anchored to the kelp and stones on the bottom. Gazing down through the clear waters one saw a white, mamillated sheath covering the jungle of giant seaweed, recalling a forest after a heavy snowfall. The ice, instead of being a dead weight bearing down the branches, tended to float, and, when accumulated in large masses, sometimes succeeded in rising to the surface, uprooting and lifting great lengths of seaweed with it. One branching stem, found floating in the harbour, measured eighteen feet in length.
Whenever a temporary calm intervened, a skin of ice quickly appeared over the whole surface of the water. In the early stages, this formation consisted of loose, blade-like crystals, previously floating freely below the surface and rising by their own buoyancy. At the surface, if undisturbed, they soon became cemented together. For example, during a calm interval on April 6, within the interval of an hour, an even crust, one inch thick, covered the sea. But the wind returned before the ice was sufficiently strong to resist it, and it all broke up and drifted away to the north, except a piece which remained wedged firmly between the sides of the boat harbour.
In the calm weather, abundant "worms" freely swimming, jelly-fish, pteropods and small fish were observed. Traps were lowered along the edge of the harbour-ice and dredgings were made in every possible situation. The bulk of the biological collecting was effected under circumstances in which Hunter and Laseron might well have given up work in disgust. For instance, I noted in my diary that on May 16, with an off shore wind of forty-three miles per hour, they and several others were dredging from the edge of the slippery bay-ice. The temperature at the time was -2 degrees F.
During April the head of the boat harbour froze over permanently, the ice reaching a thickness of eighteen inches in ten days. By that time it was strong enough to be suitable for a tide-gauge. This was one of Bage's charges, destined to take him out for many months in fair and foul weather.
There were several occasions in April when the velocity of the wind exceeded ninety miles an hour. On the evening of the 26th, the wind slackened, and for part of the 27th had almost fallen to a calm. This brought the optimists to the fore, once again, with the theory that the worst was over. The prediction was far from being fulfilled, for, as the days passed, the average velocity steadily rose. On May 11 the average for the twenty-four hours was eighty miles per hour. By that time the Hut had been further protected by a crescent of cases, erected behind the first break-wind. In height this erection stood above the Hangar, and, when the snow became piled in a solid ramp on the leeward side, it was more compact than ever. Inside the Hut extra struts were introduced, stiffening the principal rafters on the southern side. It was reassuring to know that these precautions had been taken, for, on May 15, the wind blew at an average velocity of ninety miles per hour throughout the whole twenty-four hours.
Having failed to demolish us by dogged persistence, the hurricane tried new tactics on the evening of May 24, in the form of a terrific series of Herculean gusts. As we learned afterwards, the momentary velocity of these doubtless approached two hundred miles per hour. At 11.30 P.M. the situation was cheerfully discussed, though every one was tuned up to a nervous pitch as the Hut creaked and shuddered under successive blows. It seemed very doubtful whether the roof would resist the gusts, and the feasibility of the meat cellar as a last haven of refuge was discussed. After the passage of each gust, the barometer dropped, rising again immediately afterwards. Similar pulsations of the barometer were observed many times later in the year. The maximum sudden movement noted was one-fifth inch. Had the interior of the Hut been more freely in communication with the outside air, instead of resembling a hermetically sealed box, the "kicks" would undoubtedly have been much greater.
