It was worse than absurd, it was alarming. Things grew worse. It was evident that the bears meant to stifle their prey, for the sagacious animals were heaping up huge masses, which would make escape impossible. "It is too bad," said old Johnson, with a mortified look. "One might put up with men, but bears!" [Illustration: ] Two hours elapsed without bringing any relief to the prisoners; to go out was impossible, and the thick walls excluded all sound. Altamont walked impatiently up and down full of exasperation and excitement at finding himself worsted for once. Hatteras could think of nothing but the Doctor, and of the serious peril which threatened him. [Illustration: ] "Oh, if Mr. Clawbonny were only here!" said Johnson. "What could he do?" asked Altamont. "Oh, he'd manage to get us out somehow." "How, pray?" said the American, crossly. "If I knew that I should not need him. However, I know what his advice just now would be." "What?" "To take some food; that can't hurt us. What do you say, Mr. Altamont?" "Oh, let's eat, by all means, if that will please you, though we're in a ridiculous, not to say humiliating, plight." "I'll bet you we'll find a way out after dinner." No one replied, but they seated themselves round the table. [Illustration: ] 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." CHAPTER XIII. THE MINE. Night drew on, and the lamp in the sitting-room already began to burn dim for want of oxygen. At eight o'clock the final arrangements were completed, and all that remained to do was to make an opening in the roof. They had been working away at this for some minutes, and Bell was showing himself quite an adept in the business, when Johnson, who had been keeping watch in the sleeping room, came hurriedly in to his companions, pulling such a long face, that the captain asked immediately what was the matter?
