There are no germs in the Antarctic, save for a few isolated specimens which almost certainly come down from civilization in the upper air currents. You can sleep all night in a wet bag and clothing, and sledge all day in a mail of ice, and you will not catch a cold nor get any aches. You can get deficiency diseases, like scurvy, for inland this is a deficiency country, without vitamines. You can also get poisoned if you allow your food to remain thawed out too long, and if you do not cover the provisions in a depôt with enough snow the sun will get at them, even though the air temperature is far below freezing. But it is not easy to become diseased.
On the other hand, once something does go wrong it is the deuce and all to get it right: especially cuts. And the isolation of the polar traveller may place him in most difficult circumstances. There are no ambulances and hospitals, and a man on a sledge is a very serious weight. Practically any man who undertakes big polar journeys must face the possibility of having to commit suicide to save his companions, and the difficulty of this must not be overrated, for it is in some ways more desirable to die than to live if things are bad enough: we got to that stage on the Winter Journey. I remember discussing this question with Bowers, who had a scheme of doing himself in with a pick-axe if necessity arose, though how he could have accomplished it I don't know: or, as he said, there might be a crevasse and at any rate there was the medical case. I was horrified at the time: I had never faced the thing out with myself like that.
They left the Upper Glacier Depôt under Mount Darwin on February 8. This day they collected the most important of those geological specimens to which, at Wilson's special request, they clung to the end, and which were mostly collected by him. Mount Darwin and Buckley Island, which are really the tops of high mountains, stick out of the ice at the top of the glacier, and the course ran near to both of them, but not actually up against them. Shackleton found coal on Buckley Island, and it was clear that the place was of great geological importance, for it was one of the only places in the Antarctic where fossils could be found, so far as we knew. The ice-falls stretched away as far as you could see towards the mountains which bound the glacier on either side, and as you looked upwards towards Buckley Island they were like a long breaking wave. One of the great difficulties about the Beardmore was that you saw the ice-falls as you went up, and avoided them, but coming down you knew nothing of their whereabouts until you fell into the middle of pressure and crevasses, and then it was almost impossible to say whether you should go right or left to get out.
Evans was unable to pull this day, and was detached from the sledge, but this was not necessarily a very serious sign: Shackleton on his return journey was not able to pull at this place. Wilson wrote as follows:
"February 8, Mt. Buckley Cliffs. A very busy day. We had a very cold forenoon march, blowing like blazes from the S. Birdie detached and went on ski to Mt. Darwin and collected some dolerite, the only rock he could see on the Nunatak, which was nearest. We got into a sort of crusted surface where the snow broke through nearly to our knees and the sledge-runner also. I thought at first we were all on a thinly bridged crevasse. We then came on east a bit, and gradually got worse and worse going over an ice-fall, having great trouble to prevent sledge taking charge, but eventually got down and then made N.W. or N. into the land, and camped right by the moraine under the great sandstone cliffs of Mt. Buckley, out of the wind and quite warm again: it was a wonderful change. After lunch we all geologized on till supper, and I was very late turning in, examining the moraine after supper. Socks, all strewn over the rocks, dried splendidly. Magnificent Beacon sandstone cliffs. Masses of limestone in the moraine, and dolerite crags in various places. Coal seams at all heights in the sandstone cliffs, and lumps of weathered coal with fossil vegetable. Had a regular field-day and got some splendid things in the short time."
"February 9, Moraine visit. We made our way along down the moraine, and at the end of Mt. Buckley [I] unhitched and had half an hour over the rocks and again got some good things written up in sketch-book. We then left the moraine and made a very good march on rough blue ice all day with very small and scarce scraps of névé, on one of which we camped for the night with a rather overcast foggy sky, which cleared to bright sun in the night. We are all thoroughly enjoying temps. of +10° or thereabouts now, with no wind instead of the summit winds which are incessant with temp. -20°."
"February 10. ?16 m. We made a very good forenoon march from 10 to 2.45 towards the Cloudmaker. Weather overcast gradually obscured everything in snowfall fog, starting with crystals of large size.... We had to camp after 2½ hours' afternoon march as it got too thick to see anything and we were going downhill on blue ice...."[335]
