Part 6 (1/2)
”So am I,” replied the captain; ”but we can scarcely manage it, I fear, on account of the sh.o.r.e ice. Get out a boat, Mr. Saunders, and try to fix an anchor. We may warp in a few yards.”
The anchor was fixed, and the men strained at the capstan with a will, but, notwithstanding their utmost efforts, they could not penetrate the sh.o.r.e ice. Meanwhile the wind increased, and snow began to fall in large flakes. The tide, too, as it receded, brought a stream of ice round the point ahead of them, which bore right down on their bows. At first the concussions were slight, and the bow of the s.h.i.+p turned the floes aside; but heavier ma.s.ses soon came down, and at last one fixed itself on the cable, and caused the anchor to drag with a harsh, grating sound.
Fred Ellice, who stood beside the second mate near the companion hatch, looked inquiringly at him.
”Ah! that's bad,” said Saunders, shaking his head slowly; ”I dinna like that sound. If we're carried out into the pack there, dear knows where we'll turn up in the long run.”
”Perhaps we'll turn bottom up, sir,” suggested the fat cook as he pa.s.sed at the moment with a tray of meat. Mizzle could not resist a joke--no matter how unsuitable the time or dreadful the consequences.
”Hold your tongue, sir!” exclaimed Saunders indignantly. ”Attend to your business, and speak only when you're spoken to.”
With some difficulty the ma.s.s of ice that had got foul of the cable was disengaged, but in a few moments another and a larger ma.s.s fixed upon it, and threatened to carry it away. In this extremity the captain ordered the anchor to be hove up; but this was not easily accomplished, and when at last it was hove up to the bow both flukes were found to have been broken off, and the shank was polished bright with rubbing on the rocks.
Ice now came rolling down in great quant.i.ties and with irresistible force, and at last the s.h.i.+p was whirled into the much-dreaded pack, where she became firmly embedded, and drifted along with it before the gale into the unknown regions of the North all that night. To add to their distress and danger a thick fog overspread the sea, so that they could not tell whither the ice was carrying them, and to warp out of it was impossible. There was nothing for it therefore but to drive before the gale, and take advantage of the first opening in the ice that should afford them a chance of escape.
Towards evening of the following day the gale abated, and the sun shone out bright and clear; but the pack remained close as ever, drifting steadily towards the north.
”We're far beyond the most northerly sea that has ever yet been reached,” remarked Captain Guy to Fred and Singleton, as he leaned on the weather bulwarks, and gazed wistfully over the fields of ice in which they were embedded.
”I beg your pardon for differing, Captain Guy, but I think that Captain Parry was farther north than this when he attempted to reach the Pole,”
remarked Saunders, with the air of a man who was prepared to defend his position to the last.
”Very possibly, Mr. Saunders; but I think we are at least farther north in _this_ direction than any one has yet been; at least I make it out so by the chart.”
”I'm no sure o' that,” rejoined the second mate positively; ”charts are not always to be depended on, and I've heard that whalers have been up hereabouts before now.”
”Perhaps you are right, Mr. Saunders,” replied the captain, smiling; ”nevertheless, I shall take observations, and name the various headlands, until I find that others have been here before me.--Mivins, hand me the gla.s.s; it seems to me there's a water-sky to the northward.”
”What is a water-sky, captain?” inquired Fred.
”It is a peculiar, dark appearance of the sky on the horizon, which indicates open water; just the reverse of that bright appearance which you have often seen in the distance, and which we call the ice-blink.”
”We'll have open water soon,” remarked the second mate authoritatively.
”Mr. Saunders,” said Mivins, who, having just finished clearing away and was.h.i.+ng up the _debris_ and dishes of one meal, was enjoying in complete idleness the ten minutes of leisure that intervened between that and preparations for the next--”Mr. Saunders, sir, can you _h_inform me, sir, 'ow it is that the sea don't freeze at 'ome the same as it does _h_out 'ere?”
The countenance of the second mate brightened, for he prided himself not a little on his vast and varied stores of knowledge, and nothing pleased him so much as to be questioned, particularly on knotty subjects.
”Hem! yes, Mivins, I can tell 'ee that. Ye must know that before fresh water can freeze on the surface the whole volume of it must be cooled down to 40 degrees, and _salt_ water must be cooled down to 45 degrees.
Noo, frost requires to be very long continued and very sharp indeed before it can cool the deep sea from the top to the bottom, and until it is so cooled it canna freeze.”
”Oh!” remarked Mivins, who only half understood the meaning of the explanation, ”'ow very _h_odd. But can you tell me, Mr. Saunders, 'ow it is that them 'ere _h_icebergs is made? Them's wot I don't comprehend no'ow.”
”Ay,” replied Saunders, ”there has been many a wiser head than yours, puzzled for a long time about icebergs. But if ye'll use yer eyes you'll see how they are formed. Do you see the high cliffs yonder away to the nor'-east? Weel, there are great ma.s.ses o' ice that have been formed against them by the melting and freezing of the snows of many years.
When these become too heavy to stick to the cliffs, they tumble into the sea and float away as icebergs. But the biggest bergs come from the foot of glaciers. You know what glaciers are, Mivins?”
”No, sir, I don't.”
The second mate sighed. ”They are immense acc.u.mulations of ice, Mivins, that have been formed by the freezings and meltings of the snows of hundreds of years. They cover the mountains of Norway and Switzerland, and many other places in this world, for miles and miles in extent, and sometimes they flow down and fill up whole valleys. I once saw one in Norway that filled up a valley eight miles long, two miles broad, and seven or eight' hundred feet deep; and that was only a wee bit of it, for I was told by men who had travelled over it that it covered the mountains of the interior, and made them a level field of ice, with a surface like rough, hard snow, for more than twenty miles in extent.”
