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 round, 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 upwards. 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."
But as I spoke these last words aloud, it would have been quite clear to any listener—had there been one—that I was by no means convinced of the fact. Moreover, to associate together these simple ideas and to reunite them under the form of reasoning, required some time. I could not all at once bring my brain to think.
Then another dread doubt fell upon my soul. After all, was I ahead? Of course I was. Hans was no doubt following behind, preceded by my uncle. I perfectly recollect his having stopped for a moment to strap his baggage on his shoulder. I now remembered this trifling detail. It was, I believed, just at that very moment that I had determined to continue my route.
"Again," thought I, reasoning as calmly as was possible, "there is another sure means of not losing my way, a thread to guide me through the labyrinthine subterraneous retreat—one which I had forgotten—my faithful river."
This course of reasoning roused my drooping spirits, and I resolved to resume my journey without further delay. No time was to be lost. It was at this moment that I had reason to bless the thoughtfulness of my uncle, when he refused to allow the elder hunter to close the orifices of the hot spring—that small fissure in the great mass of granite. This beneficient spring after having saved us from thirst during so many days would now enable me to regain the right road. Having come to this mental decision, I made up my mind, before I started upwards, that ablution would certainly do me a great deal of good.
I stopped to plunge my hands and forehead in the pleasant water of the Hans-bach stream, blessing its presence as a certain consolation.
Conceive my horror and stupefaction!—I was treading a hard, dusty, shingly road of granite. The stream on which I reckoned had wholly disappeared!
CHAPTER XXIV
Lost!
No words in any human language can depict my utter despair. I was literally buried alive; with no other expectation before me than to die in all the slow horrible torture of hunger and thirst. Mechanically I crawled about, feeling the dry and arid rock. Never to my fancy had I ever felt anything so dry.
But, I frantically asked myself, how had I lost the course of the flowing stream? There could be no doubt it had ceased to flow in the gallery in which I now was. I began to understand the cause of the strange silence which prevailed when last I tried if any appeal from my companions might perchance reach my ear.
It so happened that when I first took an imprudent step in the wrong direction, I did not perceive the absence of the all-important stream. It was now quite evident that when we halted, another tunnel must have received the waters of the little torrent, and that I had unconsciously entered a different gallery. To what unknown depths had my companions gone? Where was I?
How to get back? Clue or landmark there was absolutely none! My feet left no signs on the granite and shingle. My brain throbbed with agony as I tried to discover the solution of this terrible
