They were a cheery company, part-singing in the evenings and working hard all day. It was an uneventful trip, Debenham said, and very harmonious: the best trip he had down there. Both Debenham and Dickason suffered from mountain sickness, however, and they were the two smokers! The clearness of the air was marked. At 5000 feet they could plainly see Mount Melbourne and Cape Jones, between two and three hundred miles away, and several uncharted mountains over to the west, but they were unable to plot them accurately because they could get direction rays from one point only. The Sound itself was covered by cloud most of the time, but Beaufort Island and Franklin Island were clear. Unlike David's party, they could see no signs whatever of volcanic action on Mount Bird, which is almost entirely covered with ice on which it was to be expected that some mark might be left. At 9000 feet Terror looked very imposing, but Mount Bird and Terra Nova were insignificant and uninteresting. The valley between the old crater and the slopes of the second crater greatly impressed them, and they found a fine little crevassed glacier in it. Both Priestley and Debenham are of opinion that it is possible to get to Terror by this valley, and that there are no crevassed areas or impossible slopes on the way. All the same it would probably be more sensible to go from Cape Crozier.
At a point about 9000 feet up, Priestley, Gran, Abbott and Hooper started to make the ascent to the active crater on December 10. They packed the tent, poles, bags, inner cooker and cooking gear, with four days' provisions, and reached the second crater at about 11,500 feet, to be hung up by cloud all the next day. At these altitudes the temperature varied between -10° and -30°, though at sea-level simultaneously they were round about freezing-point. By 1 a.m. on the 12th the conditions were good—clear, with a southerly wind blowing the steam away from the summit. The party got away as soon as possible and reached the lip of the active crater in a few hours. Looking down they were unable to see the bottom, for it was full of steam: the sides sloped at a steep angle for some 500 feet, when they became sheer precipices: the opening appeared to be about 14,000 paces round. The top is mostly pumice, but there is also a lot of kenyte, much the same as at sea-level: the old crater was mostly kenyte, proving that this is the oldest rock of the island: felspar crystals must be continually thrown out, for they were lying about on the top of the snow; I have one nearly 3½ inches long.
Two men went back to the camp, for one had a frost-bitten foot. This left Priestley and Gran, who tried to boil the hypsometer but failed owing to the wind, which was variable and enveloped them from time to time in steam and sulphur vapour. They left a record on a cairn and started to return. But when they had got 500 feet down Priestley found that he had left a tin of exposed films on the top instead of the record. Gran said he would go back and change it. He had reached the top when there was a loud explosion: large blocks of pumice were hurled out with a big smoke cloud; probably a big bubble had burst. Gran was in the middle of it, heard it gurgle before it burst, saw "blocks of pumiceous lava, in shape like the halves of volcanic bombs, and with bunches of long, drawn-out, hair-like shreds of glass in their interior."[355] This was Pélé's hair. Gran was a bit sick from sulphur dioxide fumes afterwards. They reached Cape Royds on the 16th, the very successful trip taking fifteen days.
Meanwhile Shackleton's old hut was very pleasant at this time of year: in winter it was a bit too draughty. With bright sunlight, a lop on the sea which splashed and gurgled under the ice-foot, the beautiful mountains all round us, and the penguins nesting at our door, this was better than the Beardmore Glacier, where we had expected to be at this date. What then must it have been to the six men who were just returned from the very Gate of Hell? And the food: "Truly Shackleton's men must have fed like turkey-cocks from all the delicacies here: boiled chicken, kidneys, mushrooms, ginger, Garibaldi biscuits, soups of all kinds: it is a splendid change. Best of all are the fresh-buttered skua's eggs which we make for breakfast. In fact, life is bearable with all that has been unknown so long at last cleared up, and our anxieties for Campbell's party laid at rest."[356]
For three weeks I worked among the Adélie penguins at Cape Royds, and obtained a complete series of their embryos. It was always Wilson's idea that embryology was the next job of a vertebral zoologist down south. I have already explained that the penguin is an interesting link in the evolutionary chain, and the object of getting this embryo is to find out where the penguins come in.[357] Whether or no they are more primitive than other nonflying birds, such as the apteryx, the ostrich, the rhea and the moa, which last is only just extinct, is an open question. But wingless birds are still hanging on to the promontories of the southern continents, where there is less rivalry than in the highly populated land areas of the north. It may be that penguins are descended from ancestors who lived in the northern hemisphere in a winged condition (even now you may sometimes see them try to fly), and that they have been driven towards the south.
If penguins are primitive, it is rational to infer that the most primitive penguin is farthest south. These are the two Antarcticists, the Emperor and the Adélie. The latter appears to be the more numerous and successful of the two, and for this reason we are inclined to search among the Emperors as being among the most primitive penguins, if not the most primitive of birds now living: hence the Winter Journey. I was glad to get, in addition, this series of Adélie penguins' embryos, feeling somewhat like a giant who had wandered on to the wrong planet, and who was distinctly in the way of its true inhabitants.
We returned too late to see the eggs laid, and therefore it was impossible to tell how old the embryos were. My hopes rose, however, when I saw some eggless nests with penguins sitting upon them, but later I found that these were used as bachelor quarters by birds whose wives were sitting near. I tried taking eggs from nests and was delighted to find that new eggs appeared: these I carefully marked, and it was not until I opened one two days later to find inside an embryo at least two weeks old, that I realized that penguins added baby-snatching to their other immoralities. Some of those from whom I took eggs sat upon stones of a similar size and shape with every appearance of content: one sat upon the half of the red tin of a Dutch cheese. They are not very intelligent.
All the world loves a penguin: I think it is because in many respects they are like ourselves, and in some respects what we should like to be. Had we but half their physical courage none could stand against us. Had we a hundredth part of their maternal instinct we should have to kill our children by the thousand. Their little bodies are so full of curiosity that they have no room for fear. They like mountaineering, and joy-riding on ice-floes: they even like to drill.
One day there had been a blizzard, and lying open to the view of all was a deserted nest, a pile of coveted stones. All the surrounding rookery made their way to and fro, each husband acquiring merit, for, after each journey, he gave his wife a stone. This was the plebeian way of doing things; but my friend who stood, ever so unconcerned, upon a rock knew a trick worth two of that: he and his wife who sat so cosily upon the other side.
The victim was a third penguin. He was without a mate, but this was an opportunity to get one. With all the speed his little legs could compass he ran to and fro, taking stones from the deserted nest, laying them beneath a rock, and hurrying back for more. On that same rock was my friend. When the victim came up with his stone he had his back turned. But as soon as the stone was laid and the other gone for more, he jumped down, seized it with his beak, ran round, gave it to his wife and was back on the rock (with his back turned) before you could say Killer Whale. Every now and then he looked over his shoulder, to see where the next stone might be.
