The vast mass rose and fell in the water with a slow motion, while its higher points seemed to reach to the sky, and often to bend towards each other as if they were about to topple over. The waves furiously dashed against its base, breaking into masses of foam; while ever and anon thundering sounds, louder than any artillery, reached the ears of the voyagers, as from the mighty berg, cracking in all directions, huge pieces came tumbling down into the water. Above the thick fringe of white foam appeared an indigo tint, which grew lighter and lighter, till it shaded off from a dark-blue to the pile of pure snow which rested on the summit.

Walter could not resist the temptation of bringing Alice to see the strange and beautiful sight. Hurrying below, he wrapped her up in a warm cloak, and, calling Nub to his assistance, they brought her on deck.

“That is beautiful,” she exclaimed; “but how dreadful it would be to run against it in the dark!” she added, after a minute’s silence.

“We hope to keep too bright a lookout for anything of that sort,” said the mate; “and, happily, at night we know when we are approaching an iceberg by the peculiar coldness of the air and the white appearance which it always presents even in the darkest nights. However, there can be no doubt that many a stout ship has been cast away on such a berg as that; or on what is more dangerous still, a floating mass of sheet-ice just flush with the water.”

The mate would not allow Alice to remain long on deck for fear of her suffering from the cold, and Walter and Nub hurried her below. Walter was soon again on deck. The ship was passing the iceberg, leaving it a mile to leeward. As it drew over the quarter there was a cry from forward of “Ice ahead!” The captain was immediately called.

“Hard up with the helm!” he shouted; and the ship passed a huge mass of ice, such as the mate had before described, flush with the water. Had the ship struck against it, her fate would have been sealed. The sharpest eyes in the ship were kept on the lookout: one man on each bow, and another in the bunt of the fore-yard; the third mate forward, and one on each quarter. Two of the best hands were at the wheel; while the captain and first mate were moving about with their eyes everywhere. All knew that the slightest inattention might cause the destruction of the ship.

Hour after hour went by. No one spoke except those on the lookout or the officer in command, when the cry came from forward, “Ice on the weather bow,” “Another island ahead,” “Ice on the lee bow,” and so on. Evening at length approached. Walter for the first time became aware of the perilous position in which the ship was placed; yet his father stood calm and unmoved, as he had ever been, and not by look or gesture did he betray what he must have felt; indeed, he had too long been inured to peril of all sorts to be moved as those are who first experience it. Gradually, however, the sea began to go down and the wind to decrease, shifting more to the southward. A clear space appearing, the captain eagerly wore ship, and then hauling up on the other tack, stood to the southward, hoping to weather the icebergs among which he had before passed. The cold was as intense as before, but it could be better borne as hopes were entertained that the gale would abate, and that at length Cape Horn would be doubled.

That night, however, was one of the greatest anxiety; for, owing to the darkness, the ice-field could not be seen at any distance, and it might be impossible to escape running on it. Captain Tredeagle could therefore only commit himself and ship to the care of Heaven, and exert his utmost vigilance to avoid the surrounding dangers.

He and all on board breathed more freely when daylight returned, and the field of ice they had just weathered was seen over the quarter, with clear water ahead. A few more icebergs were passed; some near, shining brilliantly in the sun, and others appearing like clouds floating on the surface.

In two days more there was a cry of “Land on the starboard bow!” The ship rapidly neared it. The wind coming from the eastward, the reefs were shaken out of the topsails, the courses set, and she stood towards the west. The land became more and more distinct.
