“Let us follow,” said the girl. “It may know some way that does not lead to Sedna”; but she reeled from weakness as she took the pulling-rope. The Thing moved off slowly and clumsily across the ridges, heading always toward the westward and the land, and they followed, while the growling thunder at the edge of the floe rolled nearer and nearer. The floe’s lip was split and cracked in every direction for three or four miles inland, and great pans of ten-foot-thick ice, from a few yards to twenty acres square, were jolting and ducking and surging into one another, and into the yet unbroken floe, as the heavy swell took and shook and spouted between them. This battering-ram ice was, so to speak, the first army that the sea was flinging against the floe. The incessant crash and jar of these cakes almost drowned the ripping sound of sheets of pack-ice driven bodily under the floe as cards are hastily pushed under a tablecloth. Where the water was shallow these sheets would be piled one atop of the other till the bottommost touched mud fifty feet down, and the discoloured sea banked behind the muddy ice till the increasing pressure drove all forward again. In addition to the floe and the pack-ice, the gale and the currents were bringing down true bergs, sailing mountains of ice, snapped off from the Greenland side of the water or the north shore of Melville Bay. They pounded in solemnly, the waves breaking white round them, and advanced on the floe like an old-time fleet under full sail. A berg that seemed ready to carry the world before it would ground helplessly in deep water, reel over, and wallow in a lather of foam and mud and flying frozen spray, while a much smaller and lower one would rip and ride into the flat floe, flinging tons of ice on either side, and cutting a track half a mile long before it was stopped. Some fell like swords, shearing a raw-edged canal; and others splintered into a shower of blocks, weighing scores of tons apiece, that whirled and skirted among the hummocks. Others, again, rose up bodily out of the water when they shoaled, twisted as though in pain, and fell solidly on their sides, while the sea threshed over their shoulders. This trampling and crowding and bending and buckling and arching of the ice into every possible shape was going on as far as the eye could reach all along the north line of the floe. From where Kotuko and the girl were, the confusion looked no more than an uneasy, rippling, crawling movement under the horizon; but it came toward them each moment, and they could hear, far away to landward a heavy booming, as it might have been the boom of artillery through a fog. That showed that the floe was being jammed home against the iron cliffs of Bylot’s Island, the land to the southward behind them. “This has never been before,” said Kotuko, staring stupidly. “This is not the time. How can the floe break NOW?”
