"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."

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.

CHAPTER V.

FAMINE, THEN VICTORY, FOLLOWED BY DISMAY

I had only just time to replace the unfortunate document upon the table.

Professor Liedenbrock seemed to be greatly abstracted.

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.

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.

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.

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.

So I felt reassured as far as regarded this heroic method of solving the difficulty.

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:

"Will not monsieur take any supper to-night?"

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.

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.

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.

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.

Yet I was not an ill-natured fellow. Why was I dumb at such a crisis? Why so insensible to my uncle's interests?

"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.
