No one replied, but they seated themselves round the table.

Johnson, trained in Clawbonny's school, tried to be brave and unconcerned about the danger, but he could scarcely manage it. His jokes stuck in his throat. Moreover, the whole party began to feel uncomfortable. The atmosphere was getting dense, for every opening was hermetically sealed. The stoves would hardly draw, and it was evident would soon go out altogether for want of oxygen.

Hatteras was the first to see their fresh danger, and he made no attempt to hide it from his companions.

"If that is the case," said Altamont, "we must get out at all risks."

"Yes," replied Hatteras; "but let us wait till night. We will make a hole in the roof, and let in a provision of air, and then one of us can fire out of it on the bears."

"It is the only thing we can do, I suppose," said Altamont.

So it was agreed; but waiting was hard work, and Altamont could not refrain from giving vent to his impatience by thundering maledictions on the bears, and abusing the ill fate which had placed them in such an awkward and humbling predicament. "It was beasts versus men," he said, "and certainly the men cut a pretty figure."
