Early on the 23rd they started to steam along the ice-face of the barrier; and in order that nothing should be missed it was arranged that the ship should continue to skirt close to the ice-cliff, that the officers of the watch should repeatedly observe and record its height, and that three times in the twenty-four hours the ship should be stopped and a sounding taken. In this manner a comparatively accurate survey of the northern limit of the barrier was made.
On steaming along the barrier it was found that although they were far more eager to gain new information than to prove that old information was incorrect, a very strong case soon began to arise against the Parry Mountains, which Ross had described as 'probably higher than we have yet seen'; and later on it was known with absolute certainty that these mountains did not exist. This error on the part of such a trustworthy and cautious observer, Scott ascribes to the fact that Ross, having exaggerated the height of the barrier, was led to suppose that anything seen over it at a distance must be of great altitude. 'But,' he adds, 'whatever the cause, the facts show again how deceptive appearances may be and how easily errors may arise. In fact, as I have said before, one cannot always afford to trust the evidence of one's own eyes.' Though the ship was steaming along this ice-wall for several days, the passage was not in the least monotonous, because new variations were continually showing themselves, and all of them had to be carefully observed and recorded. This work continued for several days until, on January 29, they arrived at a particularly interesting place, to the southward and eastward of the extreme position reached by Ross in 1842. From that position he had reported a strong appearance of land to the southeast, and consequently all eyes were directed over the icy cliffs in that direction. But although the afternoon was bright and clear, nothing from below or from aloft could be seen, and the only conclusion to be made was that the report was based on yet another optical illusion.
But in spite of the disappointment at being unable to report that Ross's 'appearance of land' rested on solid foundations, there was on the afternoon of the 29th an indescribable sense of impending change. 'We all felt that the plot was thickening, and we could not fail to be inspirited by the fact that we had not so far encountered the heavy pack-ice which Ross reported in this region, and that consequently we were now sailing in an open sea into an unknown world.'
The course lay well to the northward of east, and the change came at 8 P.M. when suddenly the ice-cliff turned to the east, and becoming more and more irregular continued in that direction for about five miles, when again it turned sharply to the north. Into the deep bay thus formed they ran, and as the ice was approached they saw at once that it was unlike anything yet seen. The ice-foot descended to various heights of ten or twenty feet above the water, and behind it the snow surface rose in long undulating slopes to rounded ridges, the heights of which could only be guessed. Whatever doubt remained in their minds that this was snow-covered land, a sounding of 100 fathoms quickly removed it.
But what a land! On the swelling mounds of snow above them there was not one break, not a feature to give definition to the hazy outline. No scene could have been more perfectly devised to produce optical illusions. And then, while there was so much to observe, a thick fog descended, and blotted out all hope of seeing what lay beyond the ice-foot. During the afternoon of January 30 the fog was less dense, but still no sign of bare land could be seen, and it was not until the bell had sounded for the evening meal that two or three little black patches, which at first were mistaken for detached cloud, appeared. 'We gazed idly enough at them till someone remarked that he did not believe they were clouds; then all glasses were leveled; assertions and contradictions were numerous, until the small black patches gradually assumed more and more definite shape, and all agreed that at last we were looking at real live rock, the actual substance of our newly discovered land.... It is curious to reflect now on the steps which led us to the discovery of King Edward's Land, and the chain of evidence which came to us before the actual land itself was seen: at first there had been the shallow soundings, and the sight of gently rising snow-slopes, of which, in the nature of things, one is obliged to retain a doubt; then the steeper broken slopes of snow, giving a contrast to convey a surer evidence to the eye; and, finally the indubitable land itself, but even then surrounded with such mystery as to leave us far from complete satisfaction with our discovery.'
The temptation to push farther and farther to the east was almost irresistible, but with the young ice forming rapidly around them, Scott, on February 1, decided to return, and on their way back along the barrier they experienced much lower temperatures than on the outward journey. During the return journey they landed on the barrier, and on February 4 preparations for a balloon ascent were made. 'The honour,' Scott says, 'of being the first aeronaut to make an ascent in the Antarctic Regions, perhaps somewhat selfishly, I chose for myself, and I may further confess that in so doing I was contemplating the first ascent I had made in any region, and as I swayed about in what appeared a very inadequate basket and gazed down on the rapidly diminishing figures below, I felt some doubt as to whether I had been wise in my choice.'
If, however, this ascent was not altogether enjoyed by the aeronaut, it, at any rate, gave him considerable information about the barrier surface towards the south; and, to his surprise, he discovered that instead of the continuous level plain that he had expected, it continued in a series of long undulations running approximately east and west, or parallel to the barrier surface. Later on, however, when the sledge-party taken out by Armitage returned, they reported that these undulations were not gradual as had been supposed from the balloon, but that the crest of each wave was flattened into a long plateau, from which the descent into the succeeding valley was comparatively sharp. On the evening of the 4th they put out to sea again, and on the 8th they were once more in McMurdo Sound, with high hopes that they would soon find a sheltered nook in which the Discovery could winter safely, and from which the sledge-parties could set forth upon the task of exploring the vast new world around them.
Without any delay they set out to examine their immediate surroundings, and found a little bay which promised so well for the winter that Scott's determination to remain in this region was at once strengthened. The situation, however, was surrounded with difficulties, for although the ice had broken far afield it refused to move out of the small bay on which they had looked with such eager eyes; consequently they were forced to cling to the outskirts of the bay with their ice-anchors, in depths that were too great to allow the large anchors to be dropped to the bottom. The weather also was troublesome, for after the ship had lain quietly during several hours a sudden squall would fling her back on her securing ropes, and, uprooting the ice-anchors, would ultimately send her adrift.
In spite, however, of the difficulty of keeping the ship in position, steady progress was made with the work on shore, and this consisted mainly in erecting the various huts which had been brought in pieces. The original intention had been that the Discovery should not winter in the Antarctic, but should land a small party and turn northward before the season closed, and for this party a large hut had been carried south. But even when it had been decided to keep the ship as a home, it was obvious that a shelter on shore must be made before exploring parties could be safely sent away; since until the ship was frozen in a heavy gale might have driven her off her station for several days, if not altogether. In seeking winter quarters so early in February, Scott had been firmly convinced that the season was closing in. 'With no experience to guide us, our opinion could only be based on the very severe and unseasonable conditions which we had met with to the east. But now to our astonishment we could see no sign of a speedy freezing of the bay; the summer seemed to have taken a new lease, and for several weeks the fast sea-ice continued to break silently and to pass quietly away to the north in large floes.'
In addition to the erection of the main hut, two small huts which had been brought for the magnetic instruments had to be put together. The parts of these were, of course, numbered, but the wood was so badly warped that Dailey, the carpenter, had to use a lot of persuasion before the joints would fit.
