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. 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." 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. 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. 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. 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.
