CHAPTER VI

The gale—Anchored to a berg which proves to be a treacherous one—Dangers of the "pack"—Beset in the ice—Mivins shows an inquiring mind—Walruses—Gale freshens—Chains and cables—Holding on for life—An unexpected discovery—A "nip" and its terrible consequences—Yoked to an iceberg.

The narrow escape related in the last chapter was but the prelude to a night of troubles. Fortunately, as we have before mentioned, night did not now add darkness to their difficulties. Soon after passing the bergs, a stiff breeze sprang up off shore, between which and the Dolphin there was a thick belt of loose ice, or sludge, while outside, the pack was in motion, and presented a terrible scene of crashing and grinding masses under the influence of the breeze, which soon freshened to a gale.

"Keep her away two points," said Captain Guy to the man at the wheel; "we'll make fast to yonder berg, Mr. Bolton. If this gale carries us into the pack, we shall be swept far out of our course, if, indeed, we escape being nipped and sent to the bottom."

Being nipped is one of the numberless dangers to which Arctic navigators are exposed. Should a vessel get between two moving fields or floes of ice, there is a chance, especially in stormy weather, of the ice being forced together and squeezing in the sides of the ship; this is called nipping.

"Ah!" remarked Buzzby, as he stood with folded arms by the capstan, "many and many a good ship has been sent to the bottom by that same. I've see'd a brig, with my own two eyes, squeezed together a'most flat by two big floes of ice, and after doin' it they jist separated agin and let her go plump down to the bottom. Before she was nipped, the crew saved themselves by jumpin' on to the ice, and they wos picked up by our ship that wos in company."

"There's no dependin' on the ice, by no means," remarked Amos Parr; "for I've see'd the self-same sort of thing that ye mention happen to a small steamer in Davis' Straits, only instead o' crushin' it flat, the ice lifted it right high and dry out o' the water, and then let it down again, without more ado, as sound as iver."

"Get out the warps and ice-anchors there!" cried the captain.

In a moment the men were in the boats and busy heaving and planting ice-anchors, but it was not until several hours had been spent in this tedious process that they succeeded in making fast to the berg. They had barely accomplished this when the berg gave indications of breaking up, so they cast off again in great haste, and not long afterwards a mass of ice, many tons in weight, fell from the edge of the berg close to where they had been moored.

The captain now beat up for the land in the hope of finding anchoring-ground. At first the ice presented an impenetrable barrier, but at length a lead of open water was found, through which they passed to within a few hundred yards of the shore, which at this spot showed a front of high precipitous cliffs.

"Stand by to let go the anchor!" shouted the captain.

"Ay, ay, sir."

"Down your helm! Let go!"

Down went the anchor to the music of the rattling chain-cable—a sound which had not been heard since the good ship left the shores of Old England.

"If we were only a few yards farther in, sir," remarked the first-mate, "we should be better. I'm afraid of the stream of ice coming round yonder point."

"So am I," replied the captain; "but we can scarcely manage it, I fear, on account of the shore 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 shore 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 ship turned the floes aside; but heavier masses 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 passed 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 mass of ice that had got foul of the cable was disengaged, but in a few moments another and a larger mass 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 quantities and with irresistible force, and at last the ship 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 glass; 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 washing up the débris 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 hinform me, sir, 'ow it is that the sea don't freeze at 'ome the same as it does hout '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 hodd. But can you tell me, Mr. Saunders, 'ow it is that them 'ere hicebergs 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 masses 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 accumulations 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."

"You don't say so, sir!" said Mivins in surprise. "And don't they never melt?"

"No, never. What they lose in summer they more than gain in winter. Moreover, they are always in motion; but they move so slow that you may look at them ever so closely and so long, you'll not be able to observe the motion—just like the hour hand of a watch—but we know it by observing the changes from year to year. There are immense glaciers here in the Arctic Regions, and the lumps which they are constantly shedding off into the sea are the icebergs that one sees and hears so much about."
