This was, however, an excellent reason for pushing on as fast as possible, and they stumbled and floundered forward until late in the afternoon, while the ice became more rugged and broken as they proceeded. The snow had ceased, but the drifts which stretched across their path were plentiful, and they were in the midst of one when it seemed to Wyllard who was leading that they were sinking much deeper than usual. The snow was over the top of his long boots, the sled seemed very heavy, and he could hear his comrades floundering savagely. Then there was a cry behind him, and he was jerked suddenly backwards for a pace or two until he flung himself down at full length clawing at the snow. After that he was drawn back no further, but the strain upon the trace became almost insupportable, and there was still a furious scuffling behind him.

In a moment or two, however, the strain slackened, and looking round he saw Charly waist-deep in the snow. The latter struggled out with difficulty holding on by the trace, but the sled had vanished, and it was with grave misgivings that Wyllard scrambled to his feet. Then, saying nothing, they hauled with all their might, and after a tense effort that left them gasping dragged the sled back into sight. Part of its load, however, had been left behind in the yawning hole.

Charly went back a pace or two cautiously until he once more sank to the waist, and they had some trouble in dragging him clear. Then he sat down on the sled, and Wyllard stood still looking at the holes in the snow.

"Did you feel anything under you?" he asked at length in a jarring voice.

"I didn't," said Charly simply. "It was only the trace saved me from dropping through altogether, but if I'd gone a little further I'd have been in the water. Kind of snow bridge over a crevice. We broke it up, and the sled fell through."

Wyllard turned and flung the tent, their sleeping bags, and the few packages which had not fallen out off the sled, after which he hastily opened one or two of them. His companions looked at them with apprehension in their eyes until he spoke again.

"The provisions may last a week or so, if we cut down rations," he said.

He could not remember afterwards if anybody suggested it, and he fancied that the same idea occurred to all of them at once, but in another moment or two they set about undoing the traces from the sled, and making them secure about their bodies. Then for half an hour they made perilous attempt after attempt to recover the lost provisions, and signally failed. The snow broke through continuously beneath the foremost man, but it did not break away altogether, and they could not tell what lay beneath it when they had drawn him out of the hole. When it became evident that the attempt was useless they held a brief council sitting on the sled.

"I guess we don't want to go back," said Charly. "It's quite likely we've crossed a good many of these crevices, and the snow's getting soft. Besides, Dampier will have hauled off and headed for the inlet by now."

He spoke quietly, though his face was grim, and then pausing a moment waved his hand. "It seems to me," he added, "we have got to fetch the inlet while the provisions last."
