<h5 id="id00191">THE ENEMY TO BE STARVED INTO SUBMISSION</h5>
<p id="id00192" style="margin-top: 2em">"He is gone!" cried Martha, running out of her kitchen at the noise
of the violent slamming of doors.</p>
<p id="id00193">"Yes," I replied, "completely gone."</p>
<p id="id00194">"Well; and how about his dinner?" said the old servant.</p>
<p id="id00195">"He won't have any."</p>
<p id="id00196">"And his supper?"</p>
<p id="id00197">"He won't have any."</p>
<p id="id00198">"What?" cried Martha, with clasped hands.</p>
<p id="id00199">"No, my dear Martha, he will eat no more. No one in the house is to
eat anything at all. Uncle Liedenbrock is going to make us all fast
until he has succeeded in deciphering an undecipherable scrawl."</p>
<p id="id00200">"Oh, my dear! must we then all die of hunger?"</p>
<p id="id00201">I hardly dared to confess that, with so absolute a ruler as my uncle,
this fate was inevitable.</p>
<p id="id00202">The old servant, visibly moved, returned to the kitchen, moaning
piteously.</p>
<p id="id00203">When I was alone, I thought I would go and tell Gräuben all about it.
But how should I be able to escape from the house? The Professor
might return at any moment. And suppose he called me? And suppose he
tackled me again with this logomachy, which might vainly have been
set before ancient Oedipus. And if I did not obey his call, who could
answer for what might happen?</p>
<p id="id00204">The wisest course was to remain where I was. A mineralogist at
Besançon had just sent us a collection of siliceous nodules, which I
had to classify: so I set to work; I sorted, labelled, and arranged
in their own glass case all these hollow specimens, in the cavity of
each of which was a nest of little crystals.</p>
<p id="id00205">But this work did not succeed in absorbing all my attention. That old
document kept working in my brain. My head throbbed with excitement,
and I felt an undefined uneasiness. I was possessed with a
presentiment of coming evil.</p>
<p id="id00206">In an hour my nodules were all arranged upon successive shelves. Then
I dropped down into the old velvet armchair, my head thrown back and
my hands joined over it. I lighted my long crooked pipe, with a
painting on it of an idle-looking naiad; then I amused myself
watching the process of the conversion of the tobacco into carbon,
which was by slow degrees making my naiad into a negress. Now and
then I listened to hear whether a well-known step was on the stairs.
No. Where could my uncle be at that moment? I fancied him running
under the noble trees which line the road to Altona, gesticulating,
making shots with his cane, thrashing the long grass, cutting the
heads off the thistles, and disturbing the contemplative storks in
their peaceful solitude.</p>
<p id="id00207">Would he return in triumph or in discouragement? Which would get the
upper hand, he or the secret? I was thus asking myself questions, and
mechanically taking between my fingers the sheet of paper
mysteriously disfigured with the incomprehensible succession of
letters I had written down; and I repeated to myself "What does it
all mean?"</p>
<p id="id00208">I sought to group the letters so as to form words. Quite impossible!
When I put them together by twos, threes, fives or sixes, nothing
came of it but nonsense. To be sure the fourteenth, fifteenth and
sixteenth letters made the English word 'ice'; the eighty-third and
two following made 'sir'; and in the midst of the document, in the
second and third lines, I observed the words, "rots," "mutabile,"
"ira," "net," "atra."</p>
<p id="id00209">"Come now," I thought, "these words seem to justify my uncle's view
about the language of the document. In the fourth line appeared the
word "luco", which means a sacred wood. It is true that in the third
line was the word "tabiled", which looked like Hebrew, and in the
last the purely French words "mer", "arc", "mere.""</p>
<p id="id00210">All this was enough to drive a poor fellow crazy. Four different
languages in this ridiculous sentence! What connection could there
possibly be between such words as ice, sir, anger, cruel, sacred
wood, changeable, mother, bow, and sea? The first and the last might
have something to do with each other; it was not at all surprising
that in a document written in Iceland there should be mention of a
sea of ice; but it was quite another thing to get to the end of this
cryptogram with so small a clue. So I was struggling with an
insurmountable difficulty; my brain got heated, my eyes watered over
that sheet of paper; its hundred and thirty-two letters seemed to
flutter and fly around me like those motes of mingled light and
darkness which float in the air around the head when the blood is
rushing upwards with undue violence. I was a prey to a kind of
hallucination; I was stifling; I wanted air. Unconsciously I fanned
myself with the bit of paper, the back and front of which
successively came before my eyes. What was my surprise when, in one
of those rapid revolutions, at the moment when the back was turned to
me I thought I caught sight of the Latin words "craterem,"
"terrestre," and others.</p>
<p id="id00211">A sudden light burst in upon me; these hints alone gave me the first
glimpse of the truth; I had discovered the key to the cipher. To read
the document, it would not even be necessary to read it through the
paper. Such as it was, just such as it had been dictated to me, so it
might be spelt out with ease. All those ingenious professorial
combinations were coming right. He was right as to the arrangement of
the letters; he was right as to the language. He had been within a
hair's breadth of reading this Latin document from end to end; but
that hair's breadth, chance had given it to me!</p>
<p id="id00212">You may be sure I felt stirred up. My eyes were dim, I could scarcely
see. I had laid the paper upon the table. At a glance I could tell
the whole secret.</p>
<p id="id00213">At last I became more calm. I made a wise resolve to walk twice round
the room quietly and settle my nerves, and then I returned into the
deep gulf of the huge armchair.</p>
<p id="id00214">"Now I'll read it," I cried, after having well distended my lungs
with air.</p>
<p id="id00215">I leaned over the table; I laid my finger successively upon every
letter; and without a pause, without one moment's hesitation, I read
off the whole sentence aloud.</p>
<p id="id00216">Stupefaction! terror! I sat overwhelmed as if with a sudden deadly
blow. What! that which I read had actually, really been done! A
mortal man had had the audacity to penetrate! . . .</p>
<p id="id00217">"Ah!" I cried, springing up. "But no! no! My uncle shall never know
it. He would insist upon doing it too. He would want to know all
about it. Ropes could not hold him, such a determined geologist as he
is! He would start, he would, in spite of everything and everybody,
and he would take me with him, and we should never get back. No,
never! never!"</p>
<p id="id00218">My over-excitement was beyond all description.</p>
<p id="id00219">"No! no! it shall not be," I declared energetically; "and as it is in
my power to prevent the knowledge of it coming into the mind of my
tyrant, I will do it. By dint of turning this document round and
round, he too might discover the key. I will destroy it."</p>
<p id="id00220">There was a little fire left on the hearth. I seized not only the
paper but Saknussemm's parchment; with a feverish hand I was about to
fling it all upon the coals and utterly destroy and abolish this
dangerous secret, when the study door opened, and my uncle appeared.</p>
<h2 id="id00221" style="margin-top: 4em">CHAPTER V.</h2>
<h5 id="id00222">FAMINE, THEN VICTORY, FOLLOWED BY DISMAY</h5>
<p id="id00223" style="margin-top: 2em">I had only just time to replace the unfortunate document upon the
table.</p>
<p id="id00224">Professor Liedenbrock seemed to be greatly abstracted.</p>
<p id="id00225">The ruling thought gave him no rest. Evidently he had gone deeply
into the matter, analytically and with profound scrutiny. He had
brought all the resources of his mind to bear upon it during his
walk, and he had come back to apply some new combination.</p>
<p id="id00226">He sat in his armchair, and pen in hand he began what looked very
much like algebraic formula: I followed with my eyes his trembling
hands, I took count of every movement. Might not some unhoped-for
result come of it? I trembled, too, very unnecessarily, since the
true key was in my hands, and no other would open the secret.</p>
<p id="id00227">For three long hours my uncle worked on without a word, without
lifting his head; rubbing out, beginning again, then rubbing out
again, and so on a hundred times.</p>
<p id="id00228">I knew very well that if he succeeded in setting down these letters
in every possible relative position, the sentence would come out. But
I knew also that twenty letters alone could form two quintillions,
four hundred and thirty-two quadrillions, nine hundred and two
trillions, eight billions, a hundred and seventy-six millions, six
hundred and forty thousand combinations. Now, here were a hundred and
thirty-two letters in this sentence, and these hundred and thirty-two
letters would give a number of different sentences, each made up of
at least a hundred and thirty-three figures, a number which passed
far beyond all calculation or conception.</p>
<p id="id00229">So I felt reassured as far as regarded this heroic method of solving
the difficulty.</p>
<p id="id00230">But time was passing away; night came on; the street noises ceased;
my uncle, bending over his task, noticed nothing, not even Martha
half opening the door; he heard not a sound, not even that excellent
woman saying:</p>
<p id="id00231">"Will not monsieur take any supper to-night?"</p>
<p id="id00232">And poor Martha had to go away unanswered. As for me, after long
resistance, I was overcome by sleep, and fell off at the end of the
sofa, while uncle Liedenbrock went on calculating and rubbing out his
calculations.</p>
<p id="id00233">When I awoke next morning that indefatigable worker was still at his
post. His red eyes, his pale complexion, his hair tangled between his
feverish fingers, the red spots on his cheeks, revealed his desperate
struggle with impossibilities, and the weariness of spirit, the
mental wrestlings he must have undergone all through that unhappy
night.</p>
<p id="id00234">To tell the plain truth, I pitied him. In spite of the reproaches
which I considered I had a right to lay upon him, a certain feeling
of compassion was beginning to gain upon me. The poor man was so
entirely taken up with his one idea that he had even forgotten how to
get angry. All the strength of his feelings was concentrated upon one
point alone; and as their usual vent was closed, it was to be feared
lest extreme tension should give rise to an explosion sooner or later.</p>
<p id="id00235">I might with a word have loosened the screw of the steel vice that
was crushing his brain; but that word I would not speak.</p>
<p id="id00236">Yet I was not an ill-natured fellow. Why was I dumb at such a crisis?<br/>
Why so insensible to my uncle's interests?<br/></p>
<p id="id00237">"No, no," I repeated, "I shall not speak. He would insist upon going;
nothing on earth could stop him. His imagination is a volcano, and to
do that which other geologists have never done he would risk his
life. I will preserve silence. I will keep the secret which mere
chance has revealed to me. To discover it, would be to kill Professor
Liedenbrock! Let him find it out himself if he can. I will never have
it laid to my door that I led him to his destruction."</p>
<p id="id00238">Having formed this resolution, I folded my arms and waited. But I had
not reckoned upon one little incident which turned up a few hours
after.</p>
<p id="id00239">When our good Martha wanted to go to Market, she found the door
locked. The big key was gone. Who could have taken it out? Assuredly,
it was my uncle, when he returned the night before from his hurried
walk.</p>
<p id="id00240">Was this done on purpose? Or was it a mistake? Did he want to reduce
us by famine? This seemed like going rather too far! What! should
Martha and I be victims of a position of things in which we had not
the smallest interest? It was a fact that a few years before this,
whilst my uncle was working at his great classification of minerals,
he was forty-eight hours without eating, and all his household were
obliged to share in this scientific fast. As for me, what I remember
is, that I got severe cramps in my stomach, which hardly suited the
constitution of a hungry, growing lad.</p>
<p id="id00241">Now it appeared to me as if breakfast was going to be wanting, just
as supper had been the night before. Yet I resolved to be a hero, and
not to be conquered by the pangs of hunger. Martha took it very
seriously, and, poor woman, was very much distressed. As for me, the
impossibility of leaving the house distressed me a good deal more,
and for a very good reason. A caged lover's feelings may easily be
imagined.</p>
<p id="id00242">My uncle went on working, his imagination went off rambling into the
ideal world of combinations; he was far away from earth, and really
far away from earthly wants.</p>
<p id="id00243">About noon hunger began to stimulate me severely. Martha had, without
thinking any harm, cleared out the larder the night before, so that
now there was nothing left in the house. Still I held out; I made it
a point of honour.</p>
<p id="id00244">Two o'clock struck. This was becoming ridiculous; worse than that,
unbearable. I began to say to myself that I was exaggerating the
importance of the document; that my uncle would surely not believe in
it, that he would set it down as a mere puzzle; that if it came to
the worst, we should lay violent hands on him and keep him at home if
he thought on venturing on the expedition; that, after all, he might
himself discover the key of the cipher, and that then I should be
clear at the mere expense of my involuntary abstinence.</p>
<p id="id00245">These reasons seemed excellent to me, though on the night before I
should have rejected them with indignation; I even went so far as to
condemn myself for my absurdity in having waited so long, and I
finally resolved to let it all out.</p>
<p id="id00246">I was therefore meditating a proper introduction to the matter, so as
not to seem too abrupt, when the Professor jumped up, clapped on his
hat, and prepared to go out.</p>
<p id="id00247">Surely he was not going out, to shut us in again! no, never!</p>
<p id="id00248">"Uncle!" I cried.</p>
<p id="id00249">He seemed not to hear me.</p>
<p id="id00250">"Uncle Liedenbrock!" I cried, lifting up my voice.</p>
<p id="id00251">"Ay," he answered like a man suddenly waking.</p>
<p id="id00252">"Uncle, that key!"</p>
<p id="id00253">"What key? The door key?"</p>
<p id="id00254">"No, no!" I cried. "The key of the document."</p>
<p id="id00255">The Professor stared at me over his spectacles; no doubt he saw
something unusual in the expression of my countenance; for he laid
hold of my arm, and speechlessly questioned me with his eyes. Yes,
never was a question more forcibly put.</p>
<p id="id00256">I nodded my head up and down.</p>
<p id="id00257">He shook his pityingly, as if he was dealing with a lunatic. I gave a
more affirmative gesture.</p>
<p id="id00258">His eyes glistened and sparkled with live fire, his hand was shaken
threateningly.</p>
<p id="id00259">This mute conversation at such a momentous crisis would have riveted
the attention of the most indifferent. And the fact really was that I
dared not speak now, so intense was the excitement for fear lest my
uncle should smother me in his first joyful embraces. But he became
so urgent that I was at last compelled to answer.</p>
<p id="id00260">"Yes, that key, chance—"</p>
<p id="id00261">"What is that you are saying?" he shouted with indescribable emotion.</p>
<p id="id00262">"There, read that!" I said, presenting a sheet of paper on which I
had written.</p>
<p id="id00263">"But there is nothing in this," he answered, crumpling up the paper.</p>
<p id="id00264">"No, nothing until you proceed to read from the end to the beginning."</p>
<p id="id00265">I had not finished my sentence when the Professor broke out into a
cry, nay, a roar. A new revelation burst in upon him. He was
transformed!</p>
<p id="id00266">"Aha, clever Saknussemm!" he cried. "You had first written out your
sentence the wrong way."</p>
<p id="id00267">And darting upon the paper, with eyes bedimmed, and voice choked with
emotion, he read the whole document from the last letter to the first.</p>
<p id="id00268">It was conceived in the following terms:</p>
<p id="id00269"> In Sneffels Joculis craterem quem delibat<br/>
Umbra Scartaris Julii intra calendas descende,<br/>
Audax viator, et terrestre centrum attinges.<br/>
Quod feci, Arne Saknussemm.[1]<br/></p>
<p id="id00270">Which bad Latin may be translated thus:</p>
<p id="id00271">"Descend, bold traveller, into the crater of the jokul of Sneffels,
which the shadow of Scartaris touches before the kalends of July, and
you will attain the centre of the earth; which I have done, Arne
Saknussemm."</p>
<p id="id00272">In reading this, my uncle gave a spring as if he had touched a Leyden
jar. His audacity, his joy, and his convictions were magnificent to
behold. He came and he went; he seized his head between both his
hands; he pushed the chairs out of their places, he piled up his
books; incredible as it may seem, he rattled his precious nodules of
flints together; he sent a kick here, a thump there. At last his
nerves calmed down, and like a man exhausted by too lavish an
expenditure of vital power, he sank back exhausted into his armchair.</p>
<p id="id00273">"What o'clock is it?" he asked after a few moments of silence.</p>
<p id="id00274">"Three o'clock," I replied.</p>
<p id="id00275">"Is it really? The dinner-hour is past, and I did not know it. I am
half dead with hunger. Come on, and after dinner—"</p>
<p id="id00276">[1] In the cipher, <i>audax</i> is written <i>avdas,</i> and <i>quod</i> and <i>quem,</i>
<i>hod</i> and <i>ken</i>. (Tr.)</p>
<p id="id00277">"Well?"</p>
<p id="id00278">"After dinner, pack up my trunk."</p>
<p id="id00279">"What?" I cried.</p>
<p id="id00280">"And yours!" replied the indefatigable Professor, entering the
dining-room.</p>
<h2 id="id00281" style="margin-top: 4em">CHAPTER VI.</h2>
<h5 id="id00282">EXCITING DISCUSSIONS ABOUT AN UNPARALLELED ENTERPRISE</h5>
<p id="id00283" style="margin-top: 2em">At these words a cold shiver ran through me. Yet I controlled myself;
I even resolved to put a good face upon it. Scientific arguments
alone could have any weight with Professor Liedenbrock. Now there
were good ones against the practicability of such a journey.
Penetrate to the centre of the earth! What nonsense! But I kept my
dialectic battery in reserve for a suitable opportunity, and I
interested myself in the prospect of my dinner, which was not yet
forthcoming.</p>
<p id="id00284">It is no use to tell of the rage and imprecations of my uncle before
the empty table. Explanations were given, Martha was set at liberty,
ran off to the market, and did her part so well that in an hour
afterwards my hunger was appeased, and I was able to return to the
contemplation of the gravity of the situation.</p>
<p id="id00285">During all dinner time my uncle was almost merry; he indulged in some
of those learned jokes which never do anybody any harm. Dessert over,
he beckoned me into his study.</p>
<p id="id00286">I obeyed; he sat at one end of his table, I at the other.</p>
<p id="id00287">"Axel," said he very mildly; "you are a very ingenious young man, you
have done me a splendid service, at a moment when, wearied out with
the struggle, I was going to abandon the contest. Where should I have
lost myself? None can tell. Never, my lad, shall I forget it; and you
shall have your share in the glory to which your discovery will lead."</p>
<p id="id00288">"Oh, come!" thought I, "he is in a good way. Now is the time for
discussing that same glory."</p>
<p id="id00289">"Before all things," my uncle resumed, "I enjoin you to preserve the
most inviolable secrecy: you understand? There are not a few in the
scientific world who envy my success, and many would be ready to
undertake this enterprise, to whom our return should be the first
news of it."</p>
<p id="id00290">"Do you really think there are many people bold enough?" said I.</p>
<p id="id00291">"Certainly; who would hesitate to acquire such renown? If that
document were divulged, a whole army of geologists would be ready to
rush into the footsteps of Arne Saknussemm."</p>
<p id="id00292">"I don't feel so very sure of that, uncle," I replied; "for we have
no proof of the authenticity of this document."</p>
<p id="id00293">"What! not of the book, inside which we have discovered it?"</p>
<p id="id00294">"Granted. I admit that Saknussemm may have written these lines. But
does it follow that he has really accomplished such a journey? And
may it not be that this old parchment is intended to mislead?"</p>
<p id="id00295">I almost regretted having uttered this last word, which dropped from
me in an unguarded moment. The Professor bent his shaggy brows, and I
feared I had seriously compromised my own safety. Happily no great
harm came of it. A smile flitted across the lip of my severe
companion, and he answered:</p>
<p id="id00296">"That is what we shall see."</p>
<p id="id00297">"Ah!" said I, rather put out. "But do let me exhaust all the possible
objections against this document."</p>
<p id="id00298">"Speak, my boy, don't be afraid. You are quite at liberty to express
your opinions. You are no longer my nephew only, but my colleague.
Pray go on."</p>
<p id="id00299">"Well, in the first place, I wish to ask what are this Jokul, this<br/>
Sneffels, and this Scartaris, names which I have never heard before?"<br/></p>
<p id="id00300">"Nothing easier. I received not long ago a map from my friend,
Augustus Petermann, at Liepzig. Nothing could be more apropos. Take
down the third atlas in the second shelf in the large bookcase,
series Z, plate 4."</p>
<p id="id00301">I rose, and with the help of such precise instructions could not fail
to find the required atlas. My uncle opened it and said:</p>
<p id="id00302">"Here is one of the best maps of Iceland, that of Handersen, and I
believe this will solve the worst of our difficulties."</p>
<p id="id00303">I bent over the map.</p>
<p id="id00304">"You see this volcanic island," said the Professor; "observe that all
the volcanoes are called jokuls, a word which means glacier in
Icelandic, and under the high latitude of Iceland nearly all the
active volcanoes discharge through beds of ice. Hence this term of
jokul is applied to all the eruptive mountains in Iceland."</p>
<p id="id00305">"Very good," said I; "but what of Sneffels?"</p>
<p id="id00306">I was hoping that this question would be unanswerable; but I was
mistaken. My uncle replied:</p>
<p id="id00307">"Follow my finger along the west coast of Iceland. Do you see
Rejkiavik, the capital? You do. Well; ascend the innumerable fiords
that indent those sea-beaten shores, and stop at the sixty-fifth
degree of latitude. What do you see there?"</p>
<p id="id00308">"I see a peninsula looking like a thigh bone with the knee bone at
the end of it."</p>
<p id="id00309">"A very fair comparison, my lad. Now do you see anything upon that
knee bone?"</p>
<p id="id00310">"Yes; a mountain rising out of the sea."</p>
<p id="id00311">"Right. That is Snæfell."</p>
<p id="id00312">"That Snæfell?"</p>
<p id="id00313">"It is. It is a mountain five thousand feet high, one of the most
remarkable in the world, if its crater leads down to the centre of
the earth."</p>
<p id="id00314">"But that is impossible," I said shrugging my shoulders, and
disgusted at such a ridiculous supposition.</p>
<p id="id00315">"Impossible?" said the Professor severely; "and why, pray?"</p>
<p id="id00316">"Because this crater is evidently filled with lava and burning rocks,
and therefore—"</p>
<p id="id00317">"But suppose it is an extinct volcano?"</p>
<p id="id00318">"Extinct?"</p>
<p id="id00319">"Yes; the number of active volcanoes on the surface of the globe is
at the present time only about three hundred. But there is a very
much larger number of extinct ones. Now, Snæfell is one of these.
Since historic times there has been but one eruption of this
mountain, that of 1219; from that time it has quieted down more and
more, and now it is no longer reckoned among active volcanoes."</p>
<p id="id00320">To such positive statements I could make no reply. I therefore took
refuge in other dark passages of the document.</p>
<p id="id00321">"What is the meaning of this word Scartaris, and what have the
kalends of July to do with it?"</p>
<p id="id00322">My uncle took a few minutes to consider. For one short moment I felt
a ray of hope, speedily to be extinguished. For he soon answered thus:</p>
<p id="id00323">"What is darkness to you is light to me. This proves the ingenious
care with which Saknussemm guarded and defined his discovery.
Sneffels, or Snæfell, has several craters. It was therefore necessary
to point out which of these leads to the centre of the globe. What
did the Icelandic sage do? He observed that at the approach of the
kalends of July, that is to say in the last days of June, one of the
peaks, called Scartaris, flung its shadow down the mouth of that
particular crater, and he committed that fact to his document. Could
there possibly have been a more exact guide? As soon as we have
arrived at the summit of Snæfell we shall have no hesitation as to
the proper road to take."</p>
<p id="id00324">Decidedly, my uncle had answered every one of my objections. I saw
that his position on the old parchment was impregnable. I therefore
ceased to press him upon that part of the subject, and as above all
things he must be convinced, I passed on to scientific objections,
which in my opinion were far more serious.</p>
<p id="id00325">"Well, then," I said, "I am forced to admit that Saknussemm's
sentence is clear, and leaves no room for doubt. I will even allow
that the document bears every mark and evidence of authenticity. That
learned philosopher did get to the bottom of Sneffels, he has seen
the shadow of Scartaris touch the edge of the crater before the
kalends of July; he may even have heard the legendary stories told in
his day about that crater reaching to the centre of the world; but as
for reaching it himself, as for performing the journey, and
returning, if he ever went, I say no—he never, never did that."</p>
<p id="id00326">"Now for your reason?" said my uncle ironically.</p>
<p id="id00327">"All the theories of science demonstrate such a feat to be
impracticable."</p>
<p id="id00328">"The theories say that, do they?" replied the Professor in the tone
of a meek disciple. "Oh! unpleasant theories! How the theories will
hinder us, won't they?"</p>
<p id="id00329">I saw that he was only laughing at me; but I went on all the same.</p>
<p id="id00330">"Yes; it is perfectly well known that the internal temperature rises
one degree for every 70 feet in depth; now, admitting this proportion
to be constant, and the radius of the earth being fifteen hundred
leagues, there must be a temperature of 360,032 degrees at the centre
of the earth. Therefore, all the substances that compose the body of
this earth must exist there in a state of incandescent gas; for the
metals that most resist the action of heat, gold, and platinum, and
the hardest rocks, can never be either solid or liquid under such a
temperature. I have therefore good reason for asking if it is
possible to penetrate through such a medium."</p>
<p id="id00331">"So, Axel, it is the heat that troubles you?"</p>
<p id="id00332">"Of course it is. Were we to reach a depth of thirty miles we should
have arrived at the limit of the terrestrial crust, for there the
temperature will be more than 2372 degrees."</p>
<p id="id00333">"Are you afraid of being put into a state of fusion?"</p>
<p id="id00334">"I will leave you to decide that question," I answered rather
sullenly. "This is my decision," replied Professor Liedenbrock,
putting on one of his grandest airs. "Neither you nor anybody else
knows with any certainty what is going on in the interior of this
globe, since not the twelve thousandth part of its radius is known;
science is eminently perfectible; and every new theory is soon routed
by a newer. Was it not always believed until Fourier that the
temperature of the interplanetary spaces decreased perpetually? and
is it not known at the present time that the greatest cold of the
ethereal regions is never lower than 40 degrees below zero Fahr.? Why
should it not be the same with the internal heat? Why should it not,
at a certain depth, attain an impassable limit, instead of rising to
such a point as to fuse the most infusible metals?"</p>
<p id="id00335">As my uncle was now taking his stand upon hypotheses, of course,
there was nothing to be said.</p>
<p id="id00336">"Well, I will tell you that true savants, amongst them Poisson, have
demonstrated that if a heat of 360,000 degrees [1] existed in the
interior of the globe, the fiery gases arising from the fused matter
would acquire an elastic force which the crust of the earth would be
unable to resist, and that it would explode like the plates of a
bursting boiler."</p>
<p id="id00337">"That is Poisson's opinion, my uncle, nothing more."</p>
<p id="id00338">"Granted. But it is likewise the creed adopted by other distinguished
geologists, that the interior of the globe is neither gas nor water,
nor any of the heaviest minerals known, for in none of these cases
would the earth weigh what it does."</p>
<p id="id00339">"Oh, with figures you may prove anything!"</p>
<p id="id00340">"But is it the same with facts! Is it not known that the number of
volcanoes has diminished since the first days of creation? and if
there is central heat may we not thence conclude that it is in
process of diminution?"</p>
<p id="id00341">"My good uncle, if you will enter into the legion of speculation, I
can discuss the matter no longer."</p>
<p id="id00342">"But I have to tell you that the highest names have come to the
support of my views. Do you remember a visit paid to me by the
celebrated chemist, Humphry Davy, in 1825?"</p>
<p id="id00343">"Not at all, for I was not born until nineteen years afterwards."</p>
<p id="id00344">"Well, Humphry Davy did call upon me on his way through Hamburg. We
were long engaged in discussing, amongst other problems, the
hypothesis of the liquid structure of the terrestrial nucleus. We
were agreed that it could not be in a liquid state, for a reason
which science has never been able to confute."</p>
<p id="id00345">[1] The degrees of temperature are given by Jules Verne according to
the centigrade system, for which we will in each case substitute the
Fahrenheit measurement. (Tr.)</p>
<p id="id00346">"What is that reason?" I said, rather astonished.</p>
<p id="id00347">"Because this liquid mass would be subject, like the ocean, to the
lunar attraction, and therefore twice every day there would be
internal tides, which, upheaving the terrestrial crust, would cause
periodical earthquakes!"</p>
<p id="id00348">"Yet it is evident that the surface of the globe has been subject to
the action of fire," I replied, "and it is quite reasonable to
suppose that the external crust cooled down first, whilst the heat
took refuge down to the centre."</p>
<p id="id00349">"Quite a mistake," my uncle answered. "The earth has been heated by
combustion on its surface, that is all. Its surface was composed of a
great number of metals, such as potassium and sodium, which have the
peculiar property of igniting at the mere contact with air and water;
these metals kindled when the atmospheric vapours fell in rain upon
the soil; and by and by, when the waters penetrated into the fissures
of the crust of the earth, they broke out into fresh combustion with
explosions and eruptions. Such was the cause of the numerous
volcanoes at the origin of the earth."</p>
<p id="id00350">"Upon my word, this is a very clever hypothesis," I exclaimed, in
spite rather of myself.</p>
<p id="id00351">"And which Humphry Davy demonstrated to me by a simple experiment. He
formed a small ball of the metals which I have named, and which was a
very fair representation of our globe; whenever he caused a fine dew
of rain to fall upon its surface, it heaved up into little
monticules, it became oxydized and formed miniature mountains; a
crater broke open at one of its summits; the eruption took place, and
communicated to the whole of the ball such a heat that it could not
be held in the hand."</p>
<p id="id00352">In truth, I was beginning to be shaken by the Professor's arguments,
besides which he gave additional weight to them by his usual ardour
and fervent enthusiasm.</p>
<p id="id00353">"You see, Axel," he added, "the condition of the terrestrial nucleus
has given rise to various hypotheses among geologists; there is no
proof at all for this internal heat; my opinion is that there is no
such thing, it cannot be; besides we shall see for ourselves, and,
like Arne Saknussemm, we shall know exactly what to hold as truth
concerning this grand question."</p>
<p id="id00354">"Very well, we shall see," I replied, feeling myself carried off by
his contagious enthusiasm. "Yes, we shall see; that is, if it is
possible to see anything there."</p>
<p id="id00355">"And why not? May we not depend upon electric phenomena to give us
light? May we not even expect light from the atmosphere, the pressure
of which may render it luminous as we approach the centre?"</p>
<p id="id00356">"Yes, yes," said I; "that is possible, too."</p>
<p id="id00357">"It is certain," exclaimed my uncle in a tone of triumph. "But
silence, do you hear me? silence upon the whole subject; and let no
one get before us in this design of discovering the centre of the
earth."</p>
