When the sun went down in that vast waste of water which lies to the southward of this continent, the little Sea Lion had fairly lost sight of land, and was riding over the long southwestern ground-swell like a gull that holds its way steadily towards its nest. For many hours her course had not varied half a point, being as near as possible to south-southwest, which kept her a little off the wind. No sooner, however, did night come to shut in the view, than Roswell Gardiner went aft to the man at the helm, and ordered him to steer to the southward, as near as the breeze would conveniently allow. This was a material change in the direction of the vessel, and, should the present breeze stand, would probably place her, by the return of light, a good distance to the eastward of the point she would otherwise have reached. Hitherto, it had been Roswell's aim to drop his consort; but, now it was dark, and so much time had already passed and been improved since the other schooner was last seen, he believed he might venture to steer in the precise direction he desired to go. The season is so short in those seas, that every hour is precious, and no more variation from a real object could be permitted than circumstances imperiously required. It was now generally understood that the craft was making the best of her way towards her destined sealing-ground.
Independently of the discoveries of the regular explorers, a great deal of information has been obtained from the sealers themselves within the present century, touching the antarctic seas. It is thought that many a headland, and various islands, that have contributed their shares in procuring the accolades for different European navigators, were known to the adventurers from Stonington and other by-ports of this country, long before science ever laid its eyes upon them, or monarchs their swords on the shoulders of their secondary discoverers.
That divers islands existed in this quarter of the ocean was a fact recognised in geography long before the Sea Lion was thought of; probably before her young master was actually born; but the knowledge generally possessed on the subject was meagre and unsatisfactory. In particular cases, nevertheless, this remark would not apply, there being at that moment on board our little schooner several mariners who had often visited the South Shetlands, New Georgia, Palmer's Land, and other known places in those seas. Not one of them all, however, had ever heard of any island directly south of the present position of the schooner.
No material change occurred during the night, or in the course of the succeeding day, the little Sea Lion industriously holding her way toward the south pole; making very regularly her six knots each hour. By the time she was thirty-six hours from the Horn, Gardiner believed himself to be fully three degrees to the southward of it, and consequently some distance within the parallel of sixty degrees south. Palmer's Land, with its neighbouring islands, would have been near, had not the original course carried the schooner so far to the westward. As it was, no one could say what lay before them.
The third day out, the wind hauled, and it blew heavily from the north-east. This gave the adventurers a great run. The blink of ice was shortly seen, and soon after ice itself, drifting about in bergs. The floating hills were grand objects to the eye, rolling and wallowing in the seas; but they were much worn and melted by the wash of the ocean, and comparatively of greatly diminished size. It was now absolutely necessary to lose most of the hours of darkness it being much too dangerous to run in the night. The great barrier of ice was known to be close at hand; and Cook's "Ne Plus Ultra," at that time the great boundary of antarctic navigation, was near the parallel of latitude to which the schooner had reached. The weather, however, continued very favourable, and after the blow from the north-east, the wind came from the south, chill, and attended with flurries of snow, but sufficiently steady and not so fresh as to compel our adventurers to carry very short sail. The smoothness of the water would of itself have announced the vicinity of ice: not only did Gardiner's calculations tell him as much as this, but his eyes confirmed their results. In the course of the fifth day out, on several occasions when the weather cleared a little, glimpses were had of the ice in long mountainous walls, resembling many of the ridges of the Alps, though moving heavily under the heaving and setting of the restless waters. Dense fogs, from time to time, clouded the whole view, and the schooner was compelled, more than once that day, to heave-to, in order to avoid running on the sunken masses of ice, or fields, of which many of vast size now began to make their appearance.
Notwithstanding the dangers that surrounded our adventurers, they were none of them so insensible to the sublime powers of nature as to withhold their admiration from the many glorious objects which that lone and wild scene presented. The ice-bergs were of all the hues of the rainbow, as the sunlight gilded their summits or sides, or they were left shaded by the interposition of dark and murky clouds. There were instances when certain of the huge frozen masses even appeared to be quite black, in particular positions and under peculiar lights; while others, at the same instant, were gorgeous in their gleams of emerald and gold!
The aquatic birds, also, had now become numerous again. Penguins were swimming about, filling the air with their discordant cries, while there was literally no end of the cape-pigeons and petrels. Albatrosses, too, helped to make up the picture of animated nature, while whales were often heard blowing in the adjacent waters. Gardiner saw many signs of the proximity of land, and began to hope he should yet actually discover the islands laid down on his chart, as their position had been given by Daggett.
In that high latitude a degree of longitude is necessarily much shorter than when nearer to the middle of our orb. On the equator, a degree of longitude measures, as is known to most boarding-school young ladies, just sixty geographical, or sixty-nine and a half English statute miles. But, as is not known to most boarding-school young ladies, or is understood by very few of them indeed, even when known, in the sixty-second degree of latitude, a degree of longitude measures but little more than thirty-two of those very miles. The solution of this seeming contradiction is so very simple that it may assist a certain class of our readers if we explain it, by telling them that it arises solely from the fact that these degrees of longitude, which are placed sixty geographical miles asunder at the centre or middle of the earth, converge towards the poles, where they all meet in a point. According to the best observations Roswell Gardiner could obtain, he was just one of these short degrees of longitude, or two-and-thirty miles, to the westward of the parallel where he wished to be, when the wind came from the southward. The change was favourable, as it emboldened him to run nearer than he otherwise might have felt disposed to do, to the great barrier of ice which now formed a sort of weather-shore. Fortunately, the loose bergs and sunken masses had drifted off so far to the northward, that once within them the schooner had pretty plain sailing; and Roswell, to lose none of the precious time of the season, ventured to run, though under very short canvass, the whole of the short night that succeeded. It is a great assistance to the navigation of those seas that, during the summer months, there is scarcely any night at all, giving the adventurer sufficient light by which to thread his way among the difficulties of his pathless journey.
When the sun reappeared, on the morning of the sixth day after he had left the Horn, Roswell Gardiner believed himself to be far enough west for his purposes. It now remained to get a whole degree further to the south, which was a vast distance in those seas and in that direction, and would carry him a long way to the southward of the 'Ne Plus Ultra.' If there was any truth in Daggett, however, that mariner had been there; and the instructions of the owner rendered it incumbent on our young man to attempt to follow him. More than once, that morning, did our hero regret he had not entered into terms with the Vineyard men, that the effort might have been made in company. There was something so portentous in a lone vessel's venturing within the ice, in so remote a region, that, to say the truth, Roswell hesitated. But pride of profession, ambition, love of Mary, dread of the deacon, native resolution, and the hardihood produced by experience in dangers often encountered and escaped, nerved him to the undertaking. It must be attempted, or the voyage would be lost; and our young mariner now set about his task with a stern determination to achieve it.
By this time the schooner had luffed up within a cable's length of the ice, along the margin of which she was running under easy sail. Gardiner believed himself to be quite as far to the westward as was necessary, and his present object was to find an opening, by means of which he could enter among the floating chaos that was spread, far and wide, to windward. As the breeze was driving the drifting masses to the northward, they became loosened and more separated, every moment; and glad enough was Gardiner to discover, at length, a clear spot that seemed to favour his views. Without an instant's delay, the sheets were flattened in, a pull was taken on the braces, and away went the little Sea Lion into a passage that had a hundredfold more real causes of terror than the Scylla and Charybdis of old.
