"It is in the magazine."
"And the magazine?"
"This pa.s.sage-way leads to it. I had my own reason for digging this pa.s.sage sixty feet long; I might have attacked the parapet nearer to the house, but I had my own idea."
"Well, where are you going to put the mine?" asked the American.
"On the slope, as far as possible from the house, the magazine, and the stores."
"But how shall you get all the bears together?"
"I"ll take charge of that," answered the doctor; "but we"ve talked enough, now to work; we have a hundred feet to dig out to-night; it"s tiresome work, but we five can do it in relays. Bell shall begin, and meanwhile we can take some rest."
"Really," said Johnson, "the more I think of it, the more I admire Dr.
Clawbonny"s plan."
"It"s sure," answered the doctor.
"O, from the moment you opened your mouth they are dead bears, and I already feel their fur about my shoulders!"
"To work, then!"
The doctor entered the dark gallery, followed by Bell; where the doctor had gone through, his companions were sure to find no difficulty; two reached the magazine and entered among the barrels, which were all arranged in good order. The doctor gave Bell the necessary instructions; the carpenter began work on the wall towards the slope, and his companion returned to the house.

Bell worked for an hour, and dug a pa.s.sage about ten feet long, through which one might crawl. Then Altamont took his place, and did about as much; the snow which was taken from the gallery was carried into the kitchen, where the doctor melted it at the fire, that it might take up less room. The captain followed the American; then came Johnson. In ten hours, that is to say, at about eight o"clock in the morning, the gallery was finished. At daybreak the doctor peeped at the bears through a loop-hole in the wall of the powder-magazine.
The patient animals had not left their place; there they were, coming and going, growling, but in general patrolling patiently; they kept going around the house, which was gradually disappearing beneath the snow. But at length they seemed to lose patience, for the doctor saw them begin to tear away the ice and snow they had heaped up.
"Good!" he said to the captain, who was standing near him.
"What are they doing?" he asked.
"They seem to be trying to destroy what they have done and to get to us! But they"ll be destroyed first! At any rate, there is no time to lose."
The doctor made his way to the place where the mine was to be laid; then he enlarged the chamber all the height and breadth of the slope; a layer of ice, only a foot thick at the outside, remained; it had to be supported lest it should fall in. A stake resting on the granite soil served as a post; the fox"s body was fastened to the top, and a long knotted cord ran the whole length of the gallery to the magazine.
The doctor"s companions followed his orders without clearly understanding his intention.
"This is the bait," he said, pointing to the fox.
At the foot of the post he placed a cask holding about a hundred pounds of powder.
[Ill.u.s.tration]
"And here is the charge," he added.
"But," asked Hatteras, "sha"n"t we blow ourselves up at the same time?"
"No, we are far enough off from the explosion; besides, our house is solid; and if it is hurt a little we can easily repair it."
"Well," continued Altamont; "but how are you going to set it off?"
"This way. By pulling this cord we pull over the post which holds up the ice above the powder; the fox"s body will suddenly be seen on the slope, and you must confess that the starving animals will rush upon this unexpected prey."
"Certainly."
"Well, at that moment I shall explode the mine, and blow up guest and dinner."
"Well, well!" exclaimed Johnson, who was listening eagerly.
Hatteras had perfect confidence in his friend, and asked no question.
He waited. But Altamont wanted it made perfectly clear.
"Doctor," he began, "how can you calculate the length of the fuse so exactly that the explosion will take place at the right moment?"
"It"s very simple," answered the doctor; "I don"t make any calculation."
"But you have a fuse a hundred feet long?"
"No."
"Shall you set a train of powder simply?"
"No! that might fail."
"Will some one have to volunteer and light the powder?"
"If you want any one," said Johnson, eagerly, "I"m your man."
"It"s not necessary, my friend," answered the doctor, grasping the boatswain"s hand; "our five lives are precious, and they will be spared, thank G.o.d!"
"Then," said the American, "I can"t guess."
"Well," answered the doctor, smiling, "if we couldn"t get out of this little affair, what would be the use of physics?"
"Ah!" said Johnson, brightening up, "physics!"
"Yes! Haven"t we here an electric pile and wires long enough,--those, you know, which connected with the lighthouse?"
"Well?"
"Well, we shall explode the powder when we please, instantly, and without danger."
"Hurrah!" shouted Johnson.
"Hurrah!" repeated his companions, not caring whether the enemy heard them or not. Soon the electric wires were run through the gallery from the house to the chamber of the mine. One of the extremities remained at the pile, the other was plunged into the centre of the cask, the two ends being placed at but a little distance from one another. At nine of the morning all was finished, and it was time; the bears were tearing the snow away furiously. The doctor thought the proper time had come. Johnson was sent to the magazine and charged with pulling the cord fastened to the post. He took his place.
"Now," said the doctor to his companions, "load your guns in case they should not be all killed at once, and take your place near Johnson; as soon as you hear the explosion, run out."
