The Collected Works of Jules Verne: 36 Novels and Short Stories (Unexpurgated Edition) (Halcyon Classics)

by Jules Verne

  It was quite an ocean, with the irregular shores of earth, but desert and frightfully wild in appearance.

  If my eyes were able to range afar over this great sea, it was because a peculiar light brought to view every detail of it. It was not the light of the sun, with his dazzling shafts of brightness and the splendour of his rays; nor was it the pale and uncertain shimmer of the moonbeams, the dim reflection of a nobler body of light. No; the illuminating power of this light, its trembling diffusiveness, its bright, clear whiteness, and its low temperature, showed that it must be of electric origin. It was like an aurora borealis, a continuous cosmical phenomenon, filling a cavern of sufficient extent to contain an ocean.

  The vault that spanned the space above, the sky, if it could be called so, seemed composed of vast plains of cloud, shifting and variable vapours, which by their condensation must at certain times fall in torrents of rain. I should have thought that under so powerful a pressure of the atmosphere there could be no evaporation; and yet, under a law unknown to me, there were broad tracts of vapour suspended in the air. But then 'the weather was fine.' The play of the electric light produced singular effects upon the upper strata of cloud. Deep shadows reposed upon their lower wreaths; and often, between two separated fields of cloud, there glided down a ray of unspeakable lustre. But it was not solar light, and there was no heat. The general effect was sad, supremely melancholy. Instead of the shining firmament, spangled with its innumerable stars, shining singly or in clusters, I felt that all these subdued and shaded fights were ribbed in by vast walls of granite, which seemed to overpower me with their weight, and that all this space, great as it was, would not be enough for the march of the humblest of satellites.

  Then I remembered the theory of an English captain, who likened the earth to a vast hollow sphere, in the interior of which the air became luminous because of the vast pressure that weighed upon it; while two stars, Pluto and Proserpine, rolled within upon the circuit of their mysterious orbits.

  We were in reality shut up inside an immeasurable excavation. Its width could not be estimated, since the shore ran widening as far as eye could reach, nor could its length, for the dim horizon bounded the new. As for its height, it must have been several leagues. Where this vault rested upon its granite base no eye could tell; but there was a cloud hanging far above, the height of which we estimated at 12,000 feet, a greater height than that of any terrestrial vapour, and no doubt due to the great density of the air.

  The word cavern does not convey any idea of this immense space; words of human tongue are inadequate to describe the discoveries of him who ventures into the deep abysses of earth.

  Besides I could not tell upon what geological theory to account for the existence of such an excavation. Had the cooling of the globe produced it? I knew of celebrated caverns from the descriptions of travellers, but had never heard of any of such dimensions as this.

  If the grotto of Guachara, in Colombia, visited by Humboldt, had not given up the whole of the secret of its depth to the philosopher, who investigated it to the depth of 2,500 feet, it probably did not extend much farther. The immense mammoth cave in Kentucky is of gigantic proportions, since its vaulted roof rises five hundred feet [1] above the level of an unfathomable lake and travellers have explored its ramifications to the extent of forty miles. But what were these cavities compared to that in which I stood with wonder and admiration, with its sky of luminous vapours, its bursts of electric light, and a vast sea filling its bed? My imagination fell powerless before such immensity.

  I gazed upon these wonders in silence. Words failed me to express my feelings. I felt as if I was in some distant planet Uranus or Neptune - and in the presence of phenomena of which my terrestrial experience gave me no cognisance. For such novel sensations, new words were wanted; and my imagination failed to supply them. I gazed, I thought, I admired, with a stupefaction mingled with a certain amount of fear.

  The unforeseen nature of this spectacle brought back the colour to my cheeks. I was under a new course of treatment with the aid of astonishment, and my convalescence was promoted by this novel system of therapeutics; besides, the dense and breezy air invigorated me, supplying more oxygen to my lungs.

  It will be easily conceived that after an imprisonment of forty seven days in a narrow gallery it was the height of physical enjoyment to breathe a moist air impregnated with saline particles.

  [1] One hundred and twenty. (Trans.)

  I was delighted to leave my dark grotto. My uncle, already familiar with these wonders, had ceased to feel surprise.

  "You feel strong enough to walk a little way now?" he asked.

  "Yes, certainly; and nothing could be more delightful."

  "Well, take my arm, Axel, and let us follow the windings of the shore."

  I eagerly accepted, and we began to coast along this new sea. On the left huge pyramids of rock, piled one upon another, produced a prodigious titanic effect. Down their sides flowed numberless waterfalls, which went on their way in brawling but pellucid streams. A few light vapours, leaping from rock to rock, denoted the place of hot springs; and streams flowed softly down to the common basin, gliding down the gentle slopes with a softer murmur.

  Amongst these streams I recognised our faithful travelling companion, the Hansbach, coming to lose its little volume quietly in the mighty sea, just as if it had done nothing else since the beginning of the world.

  "We shall see it no more," I said, with a sigh.

  "What matters," replied the philosopher, "whether this or another serves to guide us?"

  I thought him rather ungrateful.

  But at that moment my attention was drawn to an unexpected sight. At a distance of five hundred paces, at the turn of a high promontory, appeared a high, tufted, dense forest. It was composed of trees of moderate height, formed like umbrellas, with exact geometrical outlines. The currents of wind seemed to have had no effect upon their shape, and in the midst of the windy blasts they stood unmoved and firm, just like a clump of petrified cedars.

  I hastened forward. I could not give any name to these singular creations. Were they some of the two hundred thousand species of vegetables known hitherto, and did they claim a place of their own in the lacustrine flora? No; when we arrived under their shade my surprise turned into admiration. There stood before me productions of earth, but of gigantic stature, which my uncle immediately named.

  "It is only a forest of mushrooms," said he.

  And he was right. Imagine the large development attained by these plants, which prefer a warm, moist climate. I knew that the _Lycopodon giganteum_ attains, according to Bulliard, a circumference of eight or nine feet; but here were pale mushrooms, thirty to forty feet high, and crowned with a cap of equal diameter. There they stood in thousands. No light could penetrate between their huge cones, and complete darkness reigned beneath those giants; they formed settlements of domes placed in close array like the round, thatched roofs of a central African city.

  Yet I wanted to penetrate farther underneath, though a chill fell upon me as soon as I came under those cellular vaults. For half an hour we wandered from side to side in the damp shades, and it was a comfortable and pleasant change to arrive once more upon the sea shore.

  But the subterranean vegetation was not confined to these fungi. Farther on rose groups of tall trees of colourless foliage and easy to recognise. They were lowly shrubs of earth, here attaining gigantic size; lycopodiums, a hundred feet high; the huge sigillaria, found in our coal mines; tree ferns, as tall as our fir-trees in northern latitudes; lepidodendra, with cylindrical forked stems, terminated by long leaves, and bristling with rough hairs like those of the cactus.

  "Wonderful, magnificent, splendid!" cried my uncle. "Here is the entire flora of the second period of the world - the transition period. These, humble garden plants with us, were tall trees in the early ages. Look, Axel, and admire it all. Never had botanist such a feast as this!"

  "You are right, my uncle. Providence s
eems to have preserved in this immense conservatory the antediluvian plants which the wisdom of philosophers has so sagaciously put together again."

  "It is a conservatory, Axel; but is it not also a menagerie?"

  "Surely not a menagerie!"

  "Yes; no doubt of it. Look at that dust under your feet; see the bones scattered on the ground."

  "So there are!" I cried; "bones of extinct animals."

  I had rushed upon these remains, formed of indestructible phosphates of lime, and without hesitation I named these monstrous bones, which lay scattered about like decayed trunks of trees.

  "Here is the lower jaw of a mastodon," [1] I said. "These are the molar teeth of the deinotherium; this femur must have belonged to the greatest of those beasts, the megatherium. It certainly is a menagerie, for these remains were not brought here by a deluge. The animals to which they belonged roamed on the shores of this subterranean sea, under the shade of those arborescent trees. Here are entire skeletons. And yet I cannot understand the appearance of these quadrupeds in a granite cavern."

  [1] These animals belonged to a late geological period, the Pliocene, just before the glacial epoch, and therefore could have no connection with the carboniferous vegetation. (Trans.)

  "Why?"

  "Because animal life existed upon the earth only in the secondary period, when a sediment of soil had been deposited by the rivers, and taken the place of the incandescent rocks of the primitive period."

  "Well, Axel, there is a very simple answer to your objection that this soil is alluvial."

  "What! at such a depth below the surface of the earth?"

  "No doubt; and there is a geological explanation of the fact. At a certain period the earth consisted only of an elastic crust or bark, alternately acted on by forces from above or below, according to the laws of attraction and gravitation. Probably there were subsidences of the outer crust, when a portion of the sedimentary deposits was carried down sudden openings."

  "That may be," I replied; "but if there have been creatures now extinct in these underground regions, why may not some of those monsters be now roaming through these gloomy forests, or hidden behind the steep crags?"

  And as this unpleasant notion got hold of me, I surveyed with anxious scrutiny the open spaces before me; but no living creature appeared upon the barren strand.

  I felt rather tired, and went to sit down at the end of a promontory, at the foot of which the waves came and beat themselves into spray. Thence my eye could sweep every part of the bay; within its extremity a little harbour was formed between the pyramidal cliffs, where the still waters slept untouched by the boisterous winds. A brig and two or three schooners might have moored within it in safety. I almost fancied I should presently see some ship issue from it, full sail, and take to the open sea under the southern breeze.

  But this illusion lasted a very short time. We were the only living creatures in this subterranean world. When the wind lulled, a deeper silence than that of the deserts fell upon the arid, naked rocks, and weighed upon the surface of the ocean. I then desired to pierce the distant haze, and to rend asunder the mysterious curtain that hung across the horizon. Anxious queries arose to my lips. Where did that sea terminate? Where did it lead to? Should we ever know anything about its opposite shores?

  My uncle made no doubt about it at all; I both desired and feared.

  After spending an hour in the contemplation of this marvellous spectacle, we returned to the shore to regain the grotto, and I fell asleep in the midst of the strangest thoughts.

  CHAPTER XXXI.

  PREPARATIONS FOR A VOYAGE OF DISCOVERY

  The next morning I awoke feeling perfectly well. I thought a bathe would do me good, and I went to plunge for a few minutes into the waters of this mediterranean sea, for assuredly it better deserved this name than any other sea.

  I came back to breakfast with a good appetite. Hans was a good caterer for our little household; he had water and fire at his disposal, so that he was able to vary our bill of fare now and then. For dessert he gave us a few cups of coffee, and never was coffee so delicious.

  "Now," said my uncle, "now is the time for high tide, and we must not lose the opportunity to study this phenomenon."

  "What! the tide!" I cried. "Can the influence of the sun and moon be felt down here?"

  "Why not? Are not all bodies subject throughout their mass to the power of universal attraction? This mass of water cannot escape the general law. And in spite of the heavy atmospheric pressure on the surface, you will see it rise like the Atlantic itself."

  At the same moment we reached the sand on the shore, and the waves were by slow degrees encroaching on the shore.

  "Here is the tide rising," I cried.

  "Yes, Axel; and judging by these ridges of foam, you may observe that the sea will rise about twelve feet."

  "This is wonderful," I said.

  "No; it is quite natural."

  "You may say so, uncle; but to me it is most extraordinary, and I can hardly believe my eyes. Who would ever have imagined, under this terrestrial crust, an ocean with ebbing and flowing tides, with winds and storms?"

  "Well," replied my uncle, "is there any scientific reason against it?"

  "No; I see none, as soon as the theory of central heat is given up." "So then, thus far," he answered, "the theory of Sir Humphry Davy is confirmed."

  "Evidently it is; and now there is no reason why there should not be seas and continents in the interior of the earth."

  "No doubt," said my uncle; "and inhabited too."

  "To be sure," said I; "and why should not these waters yield to us fishes of unknown species?"

  "At any rate," he replied, "we have not seen any yet."

  "Well, let us make some lines, and see if the bait will draw here as it does in sublunary regions."

  "We will try, Axel, for we must penetrate all secrets of these newly discovered regions."

  "But where are we, uncle? for I have not yet asked you that question, and your instruments must be able to furnish the answer."

  "Horizontally, three hundred and fifty leagues from Iceland."

  "So much as that?"

  "I am sure of not being a mile out of my reckoning."

  "And does the compass still show south-east?"

  "Yes; with a westerly deviation of nineteen degrees forty-five minutes, just as above ground. As for its dip, a curious fact is coming to light, which I have observed carefully: that the needle, instead of dipping towards the pole as in the northern hemisphere, on the contrary, rises from it."

  "Would you then conclude," I said, "that the magnetic pole is somewhere between the surface of the globe and the point where we are?"

  "Exactly so; and it is likely enough that if we were to reach the spot beneath the polar regions, about that seventy-first degree where Sir James Ross has discovered the magnetic pole to be situated, we should see the needle point straight up. Therefore that mysterious centre of attraction is at no great depth."

  I remarked: " It is so; and here is a fact which science has scarcely suspected."

  "Science, my lad, has been built upon many errors; but they are errors which it was good to fall into, for they led to the truth."

  "What depth have we now reached?"

  "We are thirty-five leagues below the surface."

  "So," I said, examining the map, "the Highlands of Scotland are over our heads, and the Grampians are raising their rugged summits above us."

  "Yes," answered the Professor laughing. "It is rather a heavy weight to bear, but a solid arch spans over our heads. The great Architect has built it of the best materials; and never could man have given it so wide a stretch. What are the finest arches of bridges and the arcades of cathedrals, compared with this far reaching vault, with a radius of three leagues, beneath which a wide and tempest-tossed ocean may flow at its ease?"

  "Oh, I am not afraid that it will fall down upon my head. But now what are your plans? Are you not thinking of returning to
the surface now?"

  "Return! no, indeed! We will continue our journey, everything having gone on well so far."

  "But how are we to get down below this liquid surface?"

  "Oh, I am not going to dive head foremost. But if all oceans are properly speaking but lakes, since they are encompassed by land, of course this internal sea will be surrounded by a coast of granite, and on the opposite shores we shall find fresh passages opening."

  "How long do you suppose this sea to be?"

  "Thirty or forty leagues; so that we have no time to lose, and we shall set sail to-morrow."

  I looked about for a ship.

  "Set sail, shall we? But I should like to see my boat first."

  "It will not be a boat at all, but a good, well-made raft."

  "Why," I said, "a raft would be just as hard to make as a boat, and I don't see -"

  "I know you don't see; but you might hear if you would listen. Don't you hear the hammer at work? Hans is already busy at it."

  "What, has he already felled the trees?"

  "Oh, the trees were already down. Come, and you will see for yourself."

  After half an hour's walking, on the other side of the promontory which formed the little natural harbour, I perceived Hans at work. In a few more steps I was at his side. To my great surprise a half-finished raft was already lying on the sand, made of a peculiar kind of wood, and a great number of planks, straight and bent, and of frames, were covering the ground, enough almost for a little fleet.

  "Uncle, what wood is this?" I cried.

  "It is fir, pine, or birch, and other northern coniferae, mineralised by the action of the sea. It is called surturbrand, a variety of brown coal or lignite, found chiefly in Iceland."

  "But surely, then, like other fossil wood, it must be as hard as stone, and cannot float?"
