A Journey into the Interior of the Earth by Jules Verne (books to read for 13 year olds txt) 📕

ropes were so fastened by Hans as to guard against accident, and the descent commenced. I can hardly call it perilous, for I was beginning to be familiar with this kind of exercise.

This well, or abyss, was a narrow cleft in the mass of the granite, called by geologists a 'fault,' and caused by the unequal cooling of the globe of the earth. If it had at one time been a passage for eruptive matter thrown out by Snæfell, I still could not understand why no trace was left of its passage. We kept going down a kind of winding staircase, which seemed almost to have been made by the hand of man.

Every quarter of an hour we were obliged to halt, to take a little necessary repose and restore the action of our limbs. We then sat down upon a fragment of rock, and we talked as we ate and drank from the stream.

Of course, down this fault the Hansbach fell in a cascade, and lost some of its volume; but there was enough and to spare to slake our thirst. Besides, when the incline became more gentle, it would of course resume its peaceable course. At this moment it reminded me of my worthy uncle, in his frequent fits of impatience and anger, while below it ran with the calmness of the Icelandic hunter.

On the 6th and 7th of July we kept following the spiral curves of this singular well, penetrating in actual distance no more than two leagues; but being carried to a depth of five leagues below the level of the sea. But on the 8th, about noon, the fault took, towards the south-east, a much gentler slope, one of about forty-five degrees.

Then the road became monotonously easy. It could not be otherwise, for there was no landscape to vary the stages of our journey.

On Wednesday, the 15th, we were seven leagues underground, and had travelled fifty leagues away from Snæfell. Although we were tired, our health was perfect, and the medicine chest had not yet had occasion to be opened.

My uncle noted every hour the indications of the compass, the chronometer, the aneroid, and the thermometer the very same which he has published in his scientific report of our journey. It was therefore not difficult to know exactly our whereabouts. When he told me that we had gone fifty leagues horizontally, I could not repress an exclamation of astonishment, at the thought that we had now long left Iceland behind us.

"What is the matter?" he cried.

"I was reflecting that if your calculations are correct we are no longer under Iceland."

"Do you think so?"

"I am not mistaken," I said, and examining the map, I added, "We have passed Cape Portland, and those fifty leagues bring us under the wide expanse of ocean."

"Under the sea," my uncle repeated, rubbing his hands with delight.

"Can it be?" I said. "Is the ocean spread above our heads?"

"Of course, Axel. What can be more natural? At Newcastle are there not coal mines extending far under the sea?"

It was all very well for the Professor to call this so simple, but I could not feel quite easy at the thought that the boundless ocean was rolling over my head. And yet it really mattered very little whether it was the plains and mountains that covered our heads, or the Atlantic waves, as long as we were arched over by solid granite. And, besides, I was getting used to this idea; for the tunnel, now running straight, now winding as capriciously in its inclines as in its turnings, but constantly preserving its south-easterly direction, and always running deeper, was gradually carrying us to very great depths indeed.

Four days later, Saturday, the 18th of July, in the evening, we arrived at a kind of vast grotto; and here my uncle paid Hans his weekly wages, and it was settled that the next day, Sunday, should be a day of rest.

CHAPTER XXV. DE PROFUNDIS

I therefore awoke next day relieved from the preoccupation of an immediate start. Although we were in the very deepest of known depths, there was something not unpleasant about it. And, besides, we were beginning to get accustomed to this troglodyte [1] life. I no longer thought of sun, moon, and stars, trees, houses, and towns, nor of any of those terrestrial superfluities which are necessaries of men who live upon the earth's surface. Being fossils, we looked upon all those things as mere jokes.

The grotto was an immense apartment. Along its granite floor ran our faithful stream. At this distance from its spring the water was scarcely tepid, and we drank of it with pleasure.

After breakfast the Professor gave a few hours to the arrangement of his daily notes.

"First," said he, "I will make a calculation to ascertain our exact position. I hope, after our return, to draw a map of our journey, which will be in reality a vertical section of the globe, containing the track of our expedition."

"That will be curious, uncle; but are your observations sufficiently accurate to enable you to do this correctly?"

"Yes; I have everywhere observed the angles and the inclines. I am sure there is no error. Let us see where we are now. Take your compass, and note the direction."

I looked, and replied carefully:

[1] tpwgln, a hole; dnw, to creep into. The name of an Ethiopian tribe who lived in caves and holes. ??????, a hole, and ???, to creep into.

"South-east by east."

"Well," answered the Professor, after a rapid calculation, "I infer that we have gone eighty-five leagues since we started."

"Therefore we are under mid-Atlantic?"

"To be sure we are."

"And perhaps at this very moment there is a storm above, and ships over our heads are being rudely tossed by the tempest."

"Quite probable."

"And whales are lashing the roof of our prison with their tails?"

"It may be, Axel, but they won't shake us here. But let us go back to our calculation. Here we are eighty-five leagues south-east of Snæfell, and I reckon that we are at a depth of sixteen leagues."

"Sixteen leagues?" I cried.

"No doubt."

"Why, this is the very limit assigned by science to the thickness of the crust of the earth."

"I don't deny it."

"And here, according to the law of increasing temperature, there ought to be a heat of 2,732° Fahr.!"

"So there should, my lad."

"And all this solid granite ought to be running in fusion."

"You see that it is not so, and that, as so often happens, facts come to overthrow theories."

"I am obliged to agree; but, after all, it is surprising."

"What does the thermometer say?"

"Twenty-seven, six tenths (82° Fahr.)."

"Therefore the savants are wrong by 2,705°, and the proportional increase is a mistake. Therefore Humphry Davy was right, and I am not wrong in following him. What do you say now?"

"Nothing."

In truth, I had a good deal to say. I gave way in no respect to Davy's theory. I still held to the central heat, although I did not feel its effects. I preferred to admit in truth, that this chimney of an extinct volcano, lined with lavas, which are non-conductors of heat, did not suffer the heat to pass through its walls.

But without stopping to look up new arguments I simply took up our situation such as it was.

"Well, admitting all your calculations to be quite correct, you must allow me to draw one rigid result therefrom."

"What is it. Speak freely."

"At the latitude of Iceland, where we now are, the radius of the earth, the distance from the centre to the surface is about 1,583 leagues; let us say in round numbers 1,600 leagues, or 4,800 miles. Out of 1,600 leagues we have gone twelve!"

"So you say."

"And these twelve at a cost of 85 leagues diagonally?"

"Exactly so."

"In twenty days?"

"Yes."

"Now, sixteen leagues are the hundredth part of the earth's radius. At this rate we shall be two thousand days, or nearly five years and a half, in getting to the centre."

No answer was vouchsafed to this rational conclusion. "Without reckoning, too, that if a vertical depth of sixteen leagues can be attained only by a diagonal descent of eighty-four, it follows that we must go eight thousand miles in a south-easterly direction; so that we shall emerge from some point in the earth's circumference instead of getting to the centre!"

"Confusion to all your figures, and all your hypotheses besides," shouted my uncle in a sudden rage. "What is the basis of them all? How do you know that this passage does not run straight to our destination? Besides, there is a precedent. What one man has done, another may do."

"I hope so; but, still, I may be permitted—"

"You shall have my leave to hold your tongue, Axel, but not to talk in that irrational way."

I could see the awful Professor bursting through my uncle's skin, and
I took timely warning.

"Now look at your aneroid. What does that say?"

"It says we are under considerable pressure."

"Very good; so you see that by going gradually down, and getting accustomed to the density of the atmosphere, we don't suffer at all."

"Nothing, except a little pain in the ears."

"That's nothing, and you may get rid of even that by quick breathing whenever you feel the pain."

"Exactly so," I said, determined not to say a word that might cross my uncle's prejudices. "There is even positive pleasure in living in this dense atmosphere. Have you observed how intense sound is down here?"

"No doubt it is. A deaf man would soon learn to hear perfectly."

"But won't this density augment?"

"Yes; according to a rather obscure law. It is well known that the weight of bodies diminishes as fast as we descend. You know that it is at the surface of the globe that weight is most sensibly felt, and that at the centre there is no weight at all."

"I am aware of that; but, tell me, will not air at last acquire the density of water?"

"Of course, under a pressure of seven hundred and ten atmospheres."

"And how, lower down still?"

"Lower down the density will still increase."

"But how shall we go down then."

"Why, we must fill our pockets with stones."

"Well, indeed, my worthy uncle, you are never at a loss for an answer."

I dared venture no farther into the region of probabilities, for I might presently have stumbled upon an impossibility, which would have brought the Professor on the scene when he was not wanted.

Still, it was evident that the air, under a pressure which might reach that of thousands of atmospheres, would at last reach the solid state, and then, even if our bodies could resist the strain, we should be stopped, and no reasonings would be able to get us on any farther.

But I did not advance this argument. My uncle would have met it with his inevitable Saknussemm, a precedent which possessed no weight with me; for even if the journey of the learned Icelander were really attested, there was one very simple answer, that in the sixteenth century there was neither barometer or aneroid and therefore Saknussemm could not tell how far he had gone.

But I kept this objection to myself, and waited the course of events.

The rest of the day was passed in calculations and in conversations. I remained a steadfast adherent of the opinions of Professor Liedenbrock, and I envied the stolid indifference of Hans, who, without going into causes and effects, went on with his eyes shut wherever his destiny guided him.

CHAPTER XXVI. THE WORST PERIL OF ALL

It must be confessed that hitherto things had not gone on so badly, and that I had small reason to complain. If our difficulties became no worse, we might hope to reach our end. And to what a height of scientific glory we should then attain! I had become quite a Liedenbrock in my reasonings; seriously I had. But would this state of things last in the strange place we had come to? Perhaps it might.

For several days steeper inclines, some even frightfully near to the perpendicular, brought us deeper and deeper into the mass of the interior of the earth. Some days we advanced nearer to the centre by a league and a half, or nearly two leagues. These were perilous descents, in which the skill and marvellous coolness of Hans were invaluable to
