That same night "we started to dig in under a great boulder on the top of the hill, hoping to make this a large part of one of the walls of the hut, but the rock came close underneath and stopped us. We then chose a moderately level piece of moraine about twelve feet away, and just under the level of the top of the hill, hoping that here in the lee of the ridge we might escape a good deal of the tremendous winds which we knew were common. Birdie gathered rocks from over the hill, nothing was too big for him; Bill did the banking up outside while I built the wall with the boulders. The rocks were good, the snow, however, was blown so hard as to be practically ice; a pick made little impression upon it, and the only way was to chip out big blocks gradually with the small shovel. The gravel was scanty, but good when there was any. Altogether things looked very hopeful when we turned in to the tent some 150 yards down the slope, having done about half one of the long walls."[147]
The view from eight hundred feet up the mountain was magnificent and I got my spectacles out and cleared the ice away time after time to look. To the east a great field of pressure ridges below, looking in the moonlight as if giants had been ploughing with ploughs which made furrows fifty or sixty feet deep: these ran right up to the Barrier edge, and beyond was the frozen Ross Sea, lying flat, white and peaceful as though such things as blizzards were unknown. To the north and north-east the Knoll. Behind us Mount Terror on which we stood, and over all the grey limitless Barrier seemed to cast a spell of cold immensity, vague, ponderous, a breeding-place of wind and drift and darkness. God! What a place!
"There was now little moonlight or daylight, but for the next forty-eight hours we used both to their utmost, being up at all times by day and night, and often working on when there was great difficulty in seeing anything; digging by the light of the hurricane lamp. By the end of two days we had the walls built, and banked up to one or two feet from the top; we were to fit the roof cloth close before banking up the rest. The great difficulty in banking was the hardness of the snow, it being impossible to fill in the cracks between the blocks which were more like paving-stones than anything else. The door was in, being a triangular tent doorway, with flaps which we built close in to the walls, cementing it with snow and rocks. The top folded over a plank and the bottom was dug into the ground."[148]
Birdie was very disappointed that we could not finish the whole thing that day: he was nearly angry about it, but there was a lot to do yet and we were tired out. We turned out early the next morning (Tuesday 18th) to try and finish the igloo, but it was blowing too hard. When we got to the top we did some digging but it was quite impossible to get the roof on, and we had to leave it. We realized that day that it blew much harder at the top of the slope than where our tent was. It was bitterly cold up there that morning with a wind force 4-5 and a minus thirty temperature.
The oil question was worrying us quite a lot. We were now well in to the fifth of our six tins, and economizing as much as possible, often having only two hot meals a day. We had to get down to the Emperor penguins somehow and get some blubber to run the stove which had been made for us in the hut. The 19th being a calm fine day we started at 9.30, with an empty sledge, two ice-axes, Alpine rope, harnesses and skinning tools.
Wilson had made this journey through the Cape Crozier pressure ridges several times in the Discovery days. But then they had daylight, and they had found a practicable way close under the cliffs which at the present moment were between us and the ridges.
As we neared the bottom of the mountain slope, farther to the north than we had previously gone, we had to be careful about crevasses, but we soon hit off the edge of the cliff and skirted along it until it petered out on the same level as the Barrier. Turning left handed we headed towards the sea-ice, knowing that there were some two miles of pressure between us and Cape Crozier itself. For about half a mile it was fair going, rounding big knobs of pressure but always managing to keep more or less on the flat and near the ice-cliff which soon rose to a very great height on our left. Bill's idea was to try and keep close under this cliff, along that same Discovery way which I have mentioned above. They never arrived there early enough for the eggs in those days; the chicks were hatched. Whether we should now find any Emperors, and if so whether they would have any eggs, was by no means certain.
However, we soon began to get into trouble, meeting several crevasses every few yards, and I have no doubt crossing scores of others of which we had no knowledge. Though we hugged the cliffs as close as possible we found ourselves on the top of the first pressure ridge, separated by a deep gulf from the ice-slope which we wished to reach. Then we were in a great valley between the first and second ridges: we got into huge heaps of ice pressed up in every shape on every side, crevassed in every direction: we slithered over snow-slopes and crawled along drift ridges, trying to get in towards the cliffs. And always we came up against impossible places and had to crawl back. Bill led on a length of Alpine rope fastened to the toggle of the sledge; Birdie was in his harness also fastened to the toggle, and I was in my harness fastened to the rear of the sledge, which was of great use to us both as a bridge and a ladder.
Two or three times we tried to get down the ice-slopes to the comparatively level road under the cliff, but it was always too great a drop. In that dim light every proportion was distorted; some of the places we actually did manage to negotiate with ice-axes and Alpine rope looked absolute precipices, and there were always crevasses at the bottom if you slipped. On the way back I did slip into one of these and was hauled out by the other two standing on the wall above me.
We then worked our way down into the hollow between the first and second large pressure ridges, and I believe on to the top of the second. The crests here rose fifty or sixty feet. After this I don't know where we went. Our best landmarks were patches of crevasses, sometimes three or four in a few footsteps. The temperatures were lowish (-37°), it was impossible for me to wear spectacles, and this was a tremendous difficulty to me and handicap to the party: Bill would find a crevasse and point it out; Birdie would cross; and then time after time, in trying to step over or climb over on the sledge, I put my feet right into the middle of the cracks. This day I went well in at least six times; once, when we were close to the sea, rolling into and out of one and then down a steep slope until brought up by Birdie and Bill on the rope.
We blundered along until we got into a great cul-de-sac which probably formed the end of the two ridges, where they butted on to the sea-ice. On all sides rose great walls of battered ice with steep snow-slopes in the middle, where we slithered about and blundered into crevasses. To the left rose the huge cliff of Cape Crozier, but we could not tell whether there were not two or three pressure ridges between us and it, and though we tried at least four ways, there was no possibility of getting forward.
And then we heard the Emperors calling.
Their cries came to us from the sea-ice we could not see, but which must have been a chaotic quarter of a mile away. They came echoing back from the cliffs, as we stood helpless and tantalized. We listened and realized that there was nothing for it but to return, for the little light which now came in the middle of the day was going fast, and to be caught in absolute darkness there was a horrible idea. We started back on our tracks and almost immediately I lost my footing and rolled down a slope into a crevasse. Birdie and Bill kept their balance and I clambered back to them. The tracks were very faint and we soon began to lose them. Birdie was the best man at following tracks that I have ever known, and he found them time after time. But at last even he lost them altogether and we settled we must just go ahead. As a matter of fact, we picked them up again, and by then were out of the worst: but we were glad to see the tent.
The next morning (Thursday, June 20) we started work on the igloo at 3 A.M. and managed to get the canvas roof on in spite of a wind which harried us all that day. Little did we think what that roof had in store for us as we packed it in with snow blocks, stretching it over our second sledge, which we put a
thwartships across the middle of the longer walls. The windward (south) end came right down to the ground and we tied it securely to rocks before packing it in. On the other three sides we had a good two feet or more of slack all round, and in every case we tied it to rocks by lanyards at intervals of two feet. The door was the difficulty, and for the present we left the cloth arching over the stones, forming a kind of portico. The whole was well packed in and over with slabs of hard snow, but there was no soft snow with which to fill up the gaps between the blocks. However, we felt already that nothing could drag that roof out of its packing, and subsequent events proved that we were right.
It was a bleak job for three o'clock in the morning before breakfast, and we were glad to get back to the tent and a meal, for we meant to have another go at the Emperors that day. With the first glimpse of light we were off for the rookery again.
But we now knew one or two things about that pressure which we had not known twenty-four hours ago; for instance, that there was a lot of alteration since the Discovery days and that probably the pressure was bigger. As a matter of fact it has been since proved by photographs that the ridges now ran out three-quarters of a mile farther into the sea than they did ten years before. We knew also that if we entered the pressure at the only place where the ice-cliffs came down to the level of the Barrier, as we did yesterday, we could neither penetrate to the rookery nor get in under the cliffs where formerly a possible way had been found. There was only one other thing to do—to go over the cliff. And this was what we proposed to try and do.
Now these ice-cliffs are some two hundred feet high, and I felt uncomfortable, especially in the dark. But as we came back the day before we had noticed at one place a break in the cliffs from which there hung a snow-drift. It might be possible to get down that drift.
And so, all harnessed to the sledge, with Bill on a long lead out in front and Birdie and myself checking the sledge behind, we started down the slope which ended in the cliff, which of course we could not see. We crossed a number of small crevasses, and soon we knew we must be nearly there. Twice we crept up to the edge of the cliff with no success, and then we found the slope: more, we got down it without great difficulty and it brought us out just where we wanted to be, between the land cliffs and the pressure.
Then began the most exciting climb among the pressure that you can imagine. At first very much as it was the day before—pulling ourselves and one another up ridges, slithering down slopes, tumbling into and out of crevasses and holes of all sorts, we made our way along under the cliffs which rose higher and higher above us as we neared the black lava precipices which form Cape Crozier itself. We straddled along the top of a snow ridge with a razor-backed edge, balancing the sledge between us as we wriggled: on our right was a drop of great depth with crevasses at the bottom, on our left was a smaller drop also crevassed. We crawled along, and I can tell you it was exciting work in the more than half darkness. At the end was a series of slopes full of crevasses, and finally we got right in under the rock on to moraine, and here we had to leave the sledge.
We roped up, and started to worry along under the cliffs, which had now changed from ice to rock, and rose 800 feet above us. The tumult of pressure which climbed against them showed no order here. Four hundred miles of moving ice behind it had just tossed and twisted those giant ridges until Job himself would have lacked words to reproach their Maker. We scrambled over and under, hanging on with our axes, and cutting steps where we could not find a foothold with our crampons. And always we got towards the Emperor penguins, and it really began to look as if we were going to do it this time, when we came up against a wall of ice which a single glance told us we could never cross. One of the largest pressure ridges had been thrown, end on, against the cliff. We seemed to be stopped, when Bill found a black hole, something like a fox's earth, disappearing into the bowels of the ice. We looked at it: "Well, here goes!" he said, and put his head in, and disappeared. Bowers likewise. It was a longish way, but quite possible to wriggle along, and presently I found myself looking out of the other side with a deep gully below me, the rock face on one hand and the ice on the other. "Put your back against the ice and your feet against the rock and lever yourself along," said Bill, who was already standing on firm ice at the far end in a snow pit. We cut some fifteen steps to get out of that hole. Excited by now, and thoroughly enjoying ourselves, we found the way ahead easier, until the penguins' call reached us again and we stood, three crystallized ragamuffins, above the Emperors' home. They were there all right, and we were going to reach them, but where were all the thousands of which we had heard?
We stood on an ice-foot which was really a dwarf cliff some twelve feet high, and the sea-ice, with a good many ice-blocks strewn upon it, lay below. The cliff dropped straight, with a bit of an overhang and no snow-drift. This may have been because the sea had only frozen recently; whatever the reason may have been it meant that we should have a lot of difficulty in getting up again without help. It was decided that some one must stop on the top with the Alpine rope, and clearly that one should be I, for with short sight and fogged spectacles which I could not wear I was much the least useful of the party for the job immediately ahead. Had we had the sledge we could have used it as a ladder, but of course we had left this at the beginning of the moraine miles back.
We saw the Emperors standing all together huddled under the Barrier cliff some hundreds of yards away. The little light was going fast: we were much more excited about the approach of complete darkness and the look of wind in the south than we were about our triumph. After indescribable effort and hardship we were witnessing a marvel of the natural world, and we were the first and only men who had ever done so; we had within our grasp material which might prove of the utmost importance to science; we were turning theories into facts with every observation we made,—and we had but a moment to give.
The disturbed Emperors made a tremendous row, trumpeting with their curious metallic voices. There was no doubt they had eggs, for they tried to shuffle along the ground without losing them off their feet. But when they were hustled a good many eggs were dropped and left lying on the ice, and some of these were quickly picked up by eggless Emperors who had probably been waiting a long time for the opportunity. In these poor birds the maternal side seems to have necessarily swamped the other functions of life. Such is the struggle for existence that they can only live by a glut of maternity, and it would be interesting to know whether such a life leads to happiness or satisfaction.
I have told[149] how the men of the Discovery found this rookery where we now stood. How they made journeys in the early spring but never arrived early enough to get eggs and only found parents and chicks. They concluded that the Emperor was an impossible kind of bird who, for some reason or other, nests in the middle of the Antarctic winter with the temperature anywhere below seventy degrees of frost, and the blizzards blowing, always blowing, against his devoted back. And they found him holding his precious chick balanced upon his big feet, and pressing it maternally, or paternally (for both sexes squabble for the privilege) against a bald patch in his breast. And when at last he simply must go and eat something in the open leads near by, he just puts the child down on the ice, and twenty chickless Emperors rush to pick it up. And they fight over it, and so tear it that sometimes it will die. And, if it can, it will crawl into any ice-crack to escape from so much kindness, and there it will freeze. Likewise many broken and addled eggs were found, and it is clear that the mortality is very great. But some survive, and summer comes; and when a big blizzard is going to blow (they know all about the weather), the parents take the children out for miles across the sea-ice, until they reach the threshold of the open sea. And there they sit until the wind comes, and the swell rises, and breaks that ice-floe off; and away they go in the blinding drift to join the main pack-ice, with a private yacht all to themselves.
You must agree that a bird like this is an interesting beast, and when, seven months ago, we rowed a boa
t under those great black cliffs, and found a disconsolate Emperor chick still in the down, we knew definitely why the Emperor has to nest in mid-winter. For if a June egg was still without feathers in the beginning of January, the same egg laid in the summer would leave its produce without practical covering for the following winter. Thus the Emperor penguin is compelled to undertake all kinds of hardships because his children insist on developing so slowly, very much as we are tied in our human relationships for the same reason. It is of interest that such a primitive bird should have so long a childhood.
But interesting as the life history of these birds must be, we had not travelled for three weeks to see them sitting on their eggs. We wanted the embryos, and we wanted them as young as possible, and fresh and unfrozen that specialists at home might cut them into microscopic sections and learn from them the previous history of birds throughout the evolutionary ages. And so Bill and Birdie rapidly collected five eggs, which we hoped to carry safely in our fur mitts to our igloo upon Mount Terror, where we could pickle them in the alcohol we had brought for the purpose. We also wanted oil for our blubber stove, and they killed and skinned three birds—an Emperor weighs up to 6½ stones.
The Ross Sea was frozen over, and there were no seal in sight. There were only 100 Emperors as compared with 2000 in 1902 and 1903. Bill reckoned that every fourth or fifth bird had an egg, but this was only a rough estimate, for we did not want to disturb them unnecessarily. It is a mystery why there should have been so few birds, but it certainly looked as though the ice had not formed very long. Were these the first arrivals? Had a previous rookery been blown out to sea and was this the beginning of a second attempt? Is this bay of sea-ice becoming unsafe?
