The reason was that on the night of the 17th the travelers were so exhausted that they did not heap enough snow on the skirting of the tent, and when Scott woke up on the following morning he found himself in the open. 'At first, as I lifted the flap of my sleeping-bag, I could not think what had happened. I gazed forth on a white sheet of drifting snow, with no sign of the tent or my companions. For a moment I wondered what in the world it could mean, but the lashing of the snow in my face very quickly awoke me to full consciousness, and I sat up to find that in some extraordinary way I had rolled out of the tent.' At the time a violent gale was raging, and through the blinding snow Scott could only just see the tent, though it was flapping across the foot of his bag; but when he had wriggled back to the tent the snow was whirling as freely inside as without, and the tent itself was straining so madly at what remained of its securing, that something had to be done at once to prevent it from blowing away altogether. [Page 99] So with freezing fingers they gripped the skirting and gradually pulled it inwards, and half sitting upon it, half grasping it, they tried to hold it against the wild blasts of the storm, while they discussed the situation. Discussion, however, was useless. An attempt to secure the tent properly in such weather was impossible, while they felt that if once they loosed their grip, the tent would hasten to leave them at once and for ever. Every now and then they were forced to get a fresh hold, and lever themselves once more over the skirt. And as they remained hour after hour grimly hanging on and warning each other of frostbitten features, their sleeping-bags became fuller and fuller of snow, until they were lying in masses of chilly slush. Not until 6 P.M. had they by ceaseless exertions so far become masters of the situation, that there was no further need for the tent to be held with anything except the weight of their sleeping-bags. Then an inspection of hands showed a number of frostbites, but Barne, whose fingers had not recovered from the previous year, had suffered the most. 'To have hung on to the tent through all those hours must have been positive agony to him, yet he never uttered a word of complaint.' By 10 P.M. the worst of the storm had passed, and after a few hours' sleep and a hot meal, they soon decided that to push on after this most miserable experience was very unwise, since by returning to the ship they would only lose one day's march and everything could be dried for a fresh start.
