A Journey to the Centre of the Earth by Jules Verne (ebook reader library TXT) 📗

"Yes, sir."

"Well, as long as you see them thus, you have nothing to fear from the volcano."

"How can that be?"

"Be careful to remember this," continued the Professor. "At the approach of an eruption these spouts of vapor redouble their activity—to disappear altogether during the period of volcanic eruption; for the elastic fluids, no longer having the necessary tension, seek refuge in the interior of the crater, instead of escaping through the fissures of the earth. If, then, the steam remains in its normal or habitual state, if their energy does not increase, and if you add to this, the remark that the wind is not replaced by heavy atmospheric pressure and dead calm, you may be quite sure that there is no fear of any immediate eruption."

"But—"

"Enough, my boy. When science has sent forth her fiat—it is only to hear and obey."

I came back to the house quite downcast and disappointed. My uncle had completely defeated me with his scientific arguments. Nevertheless, I had still one hope, and that was, when once we were at the bottom of the crater, that it would be impossible in default of a gallery or tunnel, to descend any deeper; and this, despite all the learned Saknussemms in the world.

I passed the whole of the following night with a nightmare on my chest! and, after unheard-of miseries and tortures, found myself in the very depths of the earth, from which I was suddenly launched into planetary space, under the form of an eruptive rock!

Next day, June 23d, Hans calmly awaited us outside the presbytery with his three companions loaded with provisions, tools, and instruments. Two iron-shod poles, two guns, and two large game bags, were reserved for my uncle and myself. Hans, who was a man who never forgot even the minutest precautions, had added to our baggage a large skin full of water, as an addition to our gourds. This assured us water for eight days.

It was nine o'clock in the morning when we were quite ready. The rector and his huge wife or servant, I never knew which, stood at the door to see us off. They appeared to be about to inflict on us the usual final kiss of the Icelanders. To our supreme astonishment their adieu took the shape of a formidable bill, in which they even counted the use of the pastoral house, really and truly the most abominable and dirty place I ever was in. The worthy couple cheated and robbed us like a Swiss innkeeper, and made us feel, by the sum we had to pay, the splendors of their hospitality.

My uncle, however, paid without bargaining. A man who had made up his mind to undertake a voyage into the Interior of the Earth, is not the man to haggle over a few miserable rix-dollars.

This important matter settled, Hans gave the signal for departure, and some few moments later we had left Stapi.

The huge volcano which was the first stage of our daring experiment is above five thousand feet high. Sneffels is the termination of a long range of volcanic mountains, of a different character to the system of the island itself. One of its peculiarities is its two huge pointed summits. From whence we started it was impossible to make out the real outlines of the peak against the grey field of sky. All we could distinguish was a vast dome of white, which fell downwards from the head of the giant.

The commencement of the great undertaking filled me with awe. Now that we had actually started, I began to believe in the reality of the undertaking!

Our party formed quite a procession. We walked in single file, preceded by Hans, the imperturbable eider-duck hunter. He calmly led us by narrow paths where two persons could by no possibility walk abreast. Conversation was wholly impossible. We had all the more opportunity to reflect and admire the awful grandeur of the scene around.

Beyond the extraordinary basaltic wall of the fjord of Stapi we found ourselves making our way through fibrous turf, over which grew a scanty vegetation of grass, the residuum of the ancient vegetation of the swampy peninsula. The vast mass of this combustible, the field of which as yet is utterly unexplored, would suffice to warm Iceland for a whole century. This mighty turf pit, measured from the bottom of certain ravines, is often not less than seventy feet deep, and presents to the eye the view of successive layers of black burned-up rocky detritus, separated by thin streaks of porous sandstone.

The grandeur of the spectacle was undoubted, as well as its arid and deserted air.

As a true nephew of the great Professor Hardwigg, and despite my preoccupation and doleful fears of what was to come, I observed with great interest the vast collection of mineralogical curiosities spread out before me in this vast museum of natural history. Looking back to my recent studies, I went over in thought the whole geological history of Iceland.

This extraordinary and curious island must have made its appearance from out of the great world of waters at a comparatively recent date. Like the coral islands of the Pacific, it may, for aught we know, be still rising by slow and imperceptible degrees.

If this really be the case, its origin can be attributed to only one cause—that of the continued action of subterranean fires.

This was a happy thought.

If so, if this were true, away with the theories of Sir Humphry Davy; away with the authority of the parchment of Arne Saknussemm; the wonderful pretensions to discovery on the part of my uncle—and to our journey!

All must end in smoke.

Charmed with the idea, I began more carefully to look about me. A serious study of the soil was necessary to negative or confirm my hypothesis. I took in every item of what I saw, and I began to comprehend the succession of phenomena which had preceded its formation.

Iceland, being absolutely without sedimentary soil, is composed exclusively of volcanic tufa; that is to say, of an agglomeration of stones and of rocks of a porous texture. Long before the existence of volcanoes, it was composed of a solid body of massive trap rock lifted bodily and slowly out of the sea, by the action of the centrifugal force at work in the earth.

The internal fires, however, had not as yet burst their bounds and flooded the exterior cake of Mother Earth with hot and raging lava.

My readers must excuse this brief and somewhat pedantic geological lecture. But it is necessary to the complete understanding of what follows.

At a later period in the world's history, a huge and mighty fissure must, reasoning by analogy, have been dug diagonally from the southwest to the northeast of the island, through which by degrees flowed the volcanic crust. The great and wondrous phenomenon then went on without violence—the outpouring was enormous, and the seething fused matter, ejected from the bowels of the earth, spread slowly and peacefully in the form of vast level plains, or what are called mamelons or mounds.

It was at this epoch that the rocks called feldspars, syenites, and porphyries appeared.

But as a natural consequence of this overflow, the depth of the island increased. It can readily be believed what an enormous quantity of elastic fluids were piled up within its centre, when at last it afforded no other openings, after the process of cooling the crust had taken place.

At length a time came when despite the enormous thickness and weight of the upper crust, the mechanical forces of the combustible gases below became so great, that they actually upheaved the weighty back and made for themselves huge and gigantic shafts. Hence the volcanoes which suddenly arose through the upper crust, and next the craters, which burst forth at the summit of these new creations.

It will be seen that the first phenomena in connection with the formation of the island were simply eruptive; to these, however, shortly succeeded the volcanic phenomena.

Through the newly formed openings, escaped the marvelous mass of basaltic stones with which the plain we were now crossing was covered. We were trampling our way over heavy rocks of dark grey color, which, while cooling, had been moulded into six-sided prisms. In the "back distance" we could see a number of flattened cones, which formerly were so many fire-vomiting mouths.

After the basaltic eruption was appeased and set at rest, the volcano, the force of which increased with that of the extinct craters, gave free passage to the fiery overflow of lava, and to the mass of cinders and pumice stone, now scattered over the sides of the mountain, like disheveled hair on the shoulders of a Bacchante.

Here, in a nutshell, I had the whole history of the phenomena from which Iceland arose. All take their rise in the fierce action of interior fires, and to believe that the central mass did not remain in a state of liquid fire, white hot, was simply and purely madness.

This being satisfactorily proved (Q.E.D.), what insensate folly to pretend to penetrate into the interior of the mighty earth!

This mental lecture delivered to myself while proceeding on a journey, did me good. I was quite reassured as to the fate of our enterprise; and therefore went, like a brave soldier mounting a bristling battery, to the assault of old Sneffels.

As we advanced, the road became every moment more difficult. The soil was broken and dangerous. The rocks broke and gave way under our feet, and we had to be scrupulously careful in order to avoid dangerous and constant falls.

Hans advanced as calmly as if he had been walking over Salisbury Plain; sometimes he would disappear behind huge blocks of stone, and we momentarily lost sight of him. There was a little period of anxiety and then there was a shrill whistle, just to tell us where to look for him.

Occasionally he would take it into his head to stop to pick up lumps of rock, and silently pile them up into small heaps, in order that we might not lose our way on our return.

He had no idea of the journey we were about to undertake.

At all events, the precaution was a good one; though how utterly useless and unnecessary—but I must not anticipate.

Three hours of terrible fatigue, walking incessantly, had only brought us to the foot of the great mountain. This will give some notion of what we had still to undergo.

Suddenly, however, Hans cried a halt—that is, he made signs to that effect—and a summary kind of breakfast was laid out on the lava before us. My uncle, who now was simply Professor Hardwigg, was so eager to advance, that he bolted his food like a greedy clown. This halt for refreshment was also a halt for repose. The Professor was therefore compelled to wait the good pleasure of his imperturbable guide, who did not give the signal for departure for a good hour.

The three Icelanders, who were as taciturn as their comrade, did not say a word; but went on eating and drinking very quietly and soberly.

From this, our first real stage, we began to ascend the slopes of the Sneffels volcano. Its magnificent snowy nightcap, as we began to call it, by an optical delusion very common in mountains, appeared to me to be close at hand; and yet how many long weary hours must elapse before we reached its summit. What unheard-of fatigue must we endure!

The stones on the mountain side, held together by no cement of soil, bound together by no roots or creeping herbs, gave way continually under our feet, and went rushing below into the plains, like a series of small avalanches.

In certain places the sides of this stupendous mountain were at an angle so steep that it was impossible to climb upwards, and we were compelled to get round these obstacles as best we might.

Those who understand Alpine climbing will comprehend our difficulties. Often we were obliged to help each other along by means of our climbing poles.

I must say this for my uncle, that he stuck as close to me as possible. He never lost sight of me, and on many occasions his arm supplied me with firm and solid support. He was strong, wiry, and apparently insensible to fatigue. Another great advantage with him was that he had the innate sentiment of equilibrium—for he never slipped or failed in his steps. The Icelanders, though heavily loaded, climbed with the agility of mountaineers.

Looking up, every now and then, at the height of the great volcano of Sneffels, it appeared to me wholly impossible to reach to the summit on that side; at all events, if the angle of inclination did not speedily change.

Fortunately, after an hour of unheard-of fatigues, and of gymnastic exercises that would have been trying to an acrobat, we came to a
