For several days after our memorable halt, the slopes became more rapid—some were even of a most frightful character—almost vertical, so that we were forever going down into the solid interior mass. During some days, we actually descended a league and a half, even two leagues toward the center of the earth. The descents were sufficiently perilous, and while we were engaged in them we learned fully to appreciate the marvelous coolness of our guide, Hans. Without him we should have been wholly lost. The grave and impassible Icelander devoted himself to us with the most incomprehensible sang-froid and ease; and, thanks to him, many a dangerous pass was got over, where, but for him, we should inevitably have stuck fast.
His silence increased every day. I think that we began to be influenced by this peculiar trait in his character. It is certain that the inanimate objects by which you are surrounded have a direct action on the brain. It must be that a man who shuts himself up between four walls must lose the faculty of associating ideas and words. How many persons condemned to the horrors of solitary confinement have gone mad—simply because the thinking faculties have lain dormant!
During the two weeks that followed our last interesting conversation, there occurred nothing worthy of being especially recorded.
I have, while writing these memoirs, taxed my memory in vain for one incident of travel during this particular period.
But the next event to be related is terrible indeed. Its very memory, even now, makes my soul shudder, and my blood run cold.
It was on the seventh of August. Our constant and successive descents had taken us quite thirty leagues into the interior of the earth, that is to say that there were above us thirty leagues, nearly a hundred miles, of rocks, and oceans, and continents, and towns, to say nothing of living inhabitants. We were in a southeasterly direction, about two hundred leagues from Iceland.
On that memorable day the tunnel had begun to assume an almost horizontal course.
I was on this occasion walking on in front. My uncle had charge of one of the Ruhmkorf coils, I had possession of the other. By means of its light I was busy examining the different layers of granite. I was completely absorbed in my work.
Suddenly halting and turning around, I found that I was alone!
“Well,” thought I to myself, “I have certainly been walking too fast—or else Hans and my uncle have stopped to rest. The best thing I can do is to go back and find them. Luckily, there is very little ascent to tire me.”
I accordingly retraced my steps and, while doing so, walked for at least a quarter of an hour. Rather uneasy, I paused and looked eagerly around. Not a living soul. I called aloud. No reply. My voice was lost amid the myriad cavernous echoes it aroused!
I began for the first time to feel seriously uneasy. A cold shiver shook my whole body, and perspiration, chill and terrible, burst upon my skin.
“I must be calm,” I said, speaking aloud, as boys whistle to drive away fear. “There can be no doubt that I shall find my companions. There cannot be two roads. It is certain that I was considerably ahead; all I have to do is to go back.”
Having come to this determination I ascended the tunnel for at least half an hour, unable to decide if I had ever seen certain landmarks before. Every now and then I paused to discover if any loud appeal was made to me, well knowing that in that dense and intensified atmosphere I should hear it a long way off. But no. The most extraordinary silence reigned in this immense gallery. Only the echoes of my own footsteps could be heard.
At last I stopped. I could scarcely realize the fact of my isolation. I was quite willing to think that I had made a mistake, but not that I was lost. If I had made a mistake, I might find my way; if lost—I shuddered to think of it.
“Come, come,” said I to myself, “since there is only one road, and they must come by it, we shall at last meet. All I have to do is still to go upward. Perhaps, however, not seeing me and forgetting I was ahead, they may have gone back in search of me. Still, even in this case, if I make haste, I shall get up to them. There can be no doubt about the matter.”
