"What do you say?" said Johnson.
"I have a companion to introduce to you," replied the Doctor, going out again into the pa.s.sage, and bringing back a dead fox, newly killed.
"I shot it this morning," he continued, "and never did fox come more opportunely."
"What on earth do you mean?" asked Altamont.
"I mean to blow up the bears en ma.s.se with 100 lbs of powder."
"But where is the powder?" exclaimed his friend.
"In the magazine. This pa.s.sage will lead to it. I made it purposely."
"And where is the mine to be?" inquired Altamont.
"At the furthest point from the house and stores."
"And how will you manage to entice the bears there, all to one spot?"
"I"ll undertake that business; but we have talked enough, let us set to work. We have a hundred feet more to add to our pa.s.sage to-night, and that is no easy matter, but as there are five of us, we can take turns at it. Bell will begin, and we will lie down and sleep meantime."
"Well, really," said Johnson, "the more I think of it, the more feasible seems the Doctor"s plan."
"It is a sure one, anyway," said Clawbonny.
"So sure that I can feel the bear"s fur already on my shoulder.
Well, come, let"s begin then."
Away he went into the gloomy pa.s.sage, followed by Bell, and in a few moments they had reached the powder-magazine, and stood among the well-arranged barrels. The Doctor pointed out to his companion the exact spot where he began excavating, and then left him to his task, at which he laboured diligently for about an hour, when Altamont came to relieve him. All the snow he had dug out was taken to the kitchen and melted, to prevent its taking up room.
The captain succeeded Altamont, and was followed by Johnson. In ten hours--that is to say, about eight in the morning--the gallery was entirely open.

With the first streak of day, the Doctor was up to reconnoitre the position of the enemy. The patient animals were still occupying their old position, prowling up and down and growling. The house had already almost disappeared beneath the piled-up blocks of ice, but even while he gazed a council of war seemed being held, which evidently resulted in the determination to alter the plan of action, for suddenly all the five bears began vigorously to pull down these same heaped-up blocks.
"What are they about?" asked Hatteras, who was standing beside him.
"Well, they look to me to be bent on demolishing their own work, and getting right down to us as fast as possible; but wait a bit, my gentlemen, we"ll demolish you first. However, we have not a minute to lose."
Hastening away to the mine, he had the chamber where the powder was to be lodged enlarged the whole breadth and height of the sloping rock against which the wall leaned, till the upper part was about a foot thick, and had to be propped up to prevent its falling in. A strong stake was fixed firmly on the granite foundation, on the top of which the dead fox was fastened. A rope was attached to the lower part of the stake, sufficiently long to reach the powder stores.
"This is the bait," he said, pointing to the dead fox, "and here is the mine," he added, rolling in a keg of powder containing about 100 lbs.
"But, Doctor," said Hatteras, "won"t that blow us up too, as well as the bears?"
"No, we shall be too far from the scene of explosion. Besides, our house is solid, and we can soon repair the walls even if they should get a bit shaken."
"And how do you propose to manage?" asked Altamont.
"See! By hauling in this rope we lower the post which props up the roof, and make it give way, and bring up the dead fox to light, and I think you will agree with me that the bears are so famished with their long fasting, that they won"t lose much time in rushing towards their unexpected meal. Well, just at that very moment, I shall set fire to the mine, and blow up both the guests and the meal."
"Capital! Capital!" shouted Johnson, who had been listening with intense interest.
[Ill.u.s.tration: ]
Hatteras said nothing, for he had such absolute confidence in his friend that he wanted no further explanation. But Altamont must know the why and wherefore of everything.
"But Doctor," he said, "can you reckon on your match so exactly that you can be quite sure it will fire the mine at the right moment?"
"I don"t need to reckon at all; that"s a difficulty easily got over."
"Then you have a match a hundred feet long?"
"No."
"You are simply going to lay a train of powder."
"No, that might miss fire."
"Well, there is no way then but for one of us to devote his life to the others, and go and light the powder himself."
"I"m ready," said Johnson, eagerly, "ready and willing."
"Quite useless my brave fellow," replied the Doctor, holding out his hand. "All our lives are precious, and they will be all spared, thank G.o.d!"
"Well, I give it up!" said the American. "I"ll make no more guesses."
"I should like to know what is the good of learning physics,"
said the Doctor, smiling, "if they can"t help a man at a pinch like this. Haven"t we an electric battery, and long enough lines attached to it to serve our purpose? We can fire our mine whenever we please in an instant, and without the slightest danger."
"Hurrah!" exclaimed Johnson.
"Hurrah!" echoed the others, without heeding whether the enemy heard them or not.
The Doctor"s idea was immediately carried out, and the connecting lines uncoiled and laid down from the house to the chamber of the mine, one end of each remaining attached to the electric pile, and the other inserted into the keg of powder.
By nine o"clock everything was ready. It was high time, for the bears were furiously engaged in the work of demolition. Johnson was stationed in the powder-magazine, in charge of the cord which held the bait.
"Now," said Clawbonny to his companions, "load your guns, in case our a.s.sailants are not killed. Stand beside Johnson, and the moment the explosion is over rush out."
[Ill.u.s.tration: ]
"All right," said Altamont.
"And now we have done all we can to help ourselves. So may Heaven help us!"
Hatteras, Altamont, and Bell repaired to the powder-magazine, while the Doctor remained alone beside the pile.
