It was dusk, and light drift commenced to scud by, so, as this was a suitable place to erect a flag, we decided to camp for the night. Some hours later I woke up to hear a blizzard blowing outside, and to find Madigan fumbling amongst some gear at the head-end of the tent. From inside my bag I called out to inquire if there was anything wrong, and received a reply that he was looking for the primus-pricker. Then he slipped back into his sleeping-bag, and all became quiet, except for the snow beating against the tent. So I presumed that he had found it. Revolving the incident in my mind, and dimly wondering what use he could have for a primus-pricker in the middle of the night, I again fell asleep. In the morning the blizzard was still blowing, accompanied by a good deal of drift. On inquiry I found that Madigan knew nothing of his midnight escapade. It was a touch of somnambulism. It would serve no useful purpose to go on in thick drift, for the main object of our journey was to define the best route through the crevassed zone; and that could only be done on a clear day. I decided, accordingly, that if the weather did not improve by noon to leave the sledge with the gear and walk back to the Hut, intending to make another attempt when conditions became more settled. Whilst the others erected a flagstaff and froze the legs of a drift-proof box (containing a thermograph) into the ice, I made lunch and prepared for our departure. The tent was taken down and everything lashed securely on the sledge. It was nearly 3 P.M. when we set out in thick drift, and in two hours we were at the Hut; the weather having steadily improved as we descended. On comparing notes with those at home it appeared that we, at the fifteen hundred feet level, had experienced much more wind and drift than they at sea-level. Webb and his assistants were beginning to make quite a display at the Magnetograph House. The framework, which had already been erected once, to be demolished by the wind, was now strongly rebuilt and was ready for the outside covering of boards. From the night of our return to March 8 there was a high wind accompanied by much drift; for some hours it continued at eighty miles per hour, the mean temperature being about 15 degrees F., with a minimum of 5 degrees F.
