"Accursed stone!" I cried furiously, on perceiving that we were stopped by what seemed an insurmountable obstacle.

In vain we looked to the right, in vain we looked to the left; in vain examined it above and below. There existed no passage, no sign of any other tunnel. I experienced the most bitter and painful disappointment. So enraged was I that I would not admit the reality of any obstacle. I stooped to my knees; I looked under the mass of stone. No hole, no interstice. I then looked above. The same barrier of granite! Hans, with the lamp, examined the sides of the tunnel in every direction.

But all in vain! It was necessary to renounce all hope of passing through.

I had seated myself upon the ground. My uncle walked angrily and hopelessly up and down. He was evidently desperate.

"But," I cried, after some moments' thought, "what about Arne Saknussemm?"

"You are right," replied my uncle, "he can never have been checked by a lump of rock."

"No--ten thousand times no," I cried, with extreme vivacity. "This huge lump of rock, in consequence of some singular concussion, or process, one of those magnetic phenomena which have so often shaken the terrestrial crust, has in some unexpected way closed up the passage. Many and many years have passed away since the return of Saknussemm, and the fall of this huge block of granite. Is it not quite evident that this gallery was formerly the outlet for the pent-up lava in the interior of the earth, and that these eruptive matters then circulated freely? Look at these recent fissures in the granite roof; it is evidently formed of pieces of enormous stone, placed here as if by the hand of a giant, who had worked to make a strong and substantial arch. One day, after an unusually strong shock, the vast rock which stands in our way, and which was doubtless the key of a kind of arch, fell through to a level with the soil and has barred our further progress. We are right, then, in thinking that this is an unexpected obstacle, with which Saknussemm did not meet; and if we do not upset it in some way, we are unworthy of following in the footsteps of the great discoverer; and incapable of finding our way to the centre of the earth!"

In this wild way I addressed my uncle. The zeal of the Professor, his earnest longing for success, had become part and parcel of my being. I wholly forgot the past; I utterly despised the future. Nothing existed for me upon the surface of this spheroid in the bosom of which I was engulfed, no towns, no country, no Hamburg, no Koenigstrasse, not even my poor Gretchen, who by this time would believe me utterly lost in the interior of the earth!

"Well," cried my uncle, roused to enthusiasm by my words, "Let us go to work with pickaxes, with crowbars, with anything that comes to hand--but down with these terrible walls."

"It is far too tough and too big to be destroyed by a pickax or crowbar," I replied.

"What then?"

"As I said, it is useless to think of overcoming such a difficulty by means of ordinary tools."

"What then?"

"What else but gunpowder, a subterranean mine? Let us blow up the obstacle that stands in our way."

"Gunpowder!"

"Yes; all we have to do is to get rid of this paltry obstacle."

"To work, Hans, to work!" cried the Professor.

The Icelander went back to the raft, and soon returned with a huge crowbar, with which he began to dig a hole in the rock, which was to serve as a mine. It was by no means a slight task. It was necessary for our purpose to make a cavity large enough to hold fifty pounds of fulminating gun cotton, the expansive power of which is four times as great as that of ordinary gunpowder.

I had now roused myself to an almost miraculous state of excitement. While Hans was at work, I actively assisted my uncle to prepare a long wick, made from damp gunpowder, the mass of which we finally enclosed in a bag of linen.

"We are bound to go through," I cried, enthusiastically.

"We are bound to go through," responded the Professor, tapping me on the back.

At midnight, our work as miners was completely finished; the charge of fulminating cotton was thrust into the hollow, and the match, which we had made of considerable length, was ready.

A spark was now sufficient to ignite this formidable engine, and to blow the rock to atoms!

"We will now rest until tomorrow."

It was absolutely necessary to resign myself to my fate, and to consent to wait for the explosion for six weary hours!

CHAPTER 39

THE EXPLOSION AND ITS RESULTS

The next day, which was the twenty-seventh of August, was a date celebrated in our wondrous subterranean journey. I never think of it even now, but I shudder with horror. My heart beats wildly at the very memory of that awful day.

From this time forward, our reason, our judgment, our human ingenuity, have nothing to do with the course of events. We are about to become the plaything of the great phenomena of the earth!

At six o'clock we were all up and ready. The dreaded moment was arriving when we were about to seek an opening into the interior of the earth by means of gunpowder. What would be the consequences of breaking through the crust of the earth?

I begged that it might be my duty to set fire to the mine. I looked upon it as an honor. This task once performed, I could rejoin my friends upon the raft, which had not been unloaded. As soon as we were all ready, we were to sail away to some distance to avoid the consequences of the explosion, the effects of which would certainly not be concentrated in the interior of the earth.

The slow match we calculated to burn for about ten minutes, more or less, before it reached the chamber in which the great body of powder was confined. I should therefore have plenty of time to reach the raft and put off to a safe distance.

I prepared to execute my self-allotted task--not, it must be confessed, without considerable emotion.

After a hearty repast, my uncle and the hunter-guide embarked on board the raft, while I remained alone upon the desolate shore.

I was provided with a lantern which was to enable me to set fire to the wick of the infernal machine.

"Go, my boy," said my uncle, "and Heaven be with you. But come back as soon as you can. I shall be all impatience."

"Be easy on that matter," I replied, "there is no fear of my delaying on the road."

Having said this, I advanced toward the opening of the somber gallery. My heart beat wildly. I opened my lantern and seized the extremity of the wick.

The Professor, who was looking on, held his chronometer in his hand.

"Are you ready?" cried he.

"Quite ready."

"Well, then, fire away!"

I hastened to put the light to the wick, which crackled and sparkled, hissing and spitting like a serpent; then, running as fast as I could, I returned to the shore.

"Get on board, my lad, and you, Hans, shove off," cried my uncle.

By a vigorous application of his pole Hans sent us flying over the water. The raft was quite twenty fathoms distant.

It was a moment of palpitating interest, of deep anxiety. My uncle, the Professor, never took his eyes off the chronometer.

"Only five minutes more," he said in a low tone, "only four, only three."

My pulse went a hundred to the minute. I could hear my heart beating.

"Only two, one! Now, then, mountains of granite, crumble beneath the power of man!"

What happened after that? As to the terrific roar of the explosion, I do not think I heard it. But the form of the rocks completely changed in my eyes--they seemed to be drawn aside like a curtain. I saw a fathomless, a bottomless abyss, which yawned beneath the turgid waves. The sea, which seemed suddenly to have gone mad, then became one great mountainous mass, upon the top of which the raft rose perpendicularly.
