Above were miles upon miles of the earth's crust. As I thought of it, I could fancy the whole weight resting on my shoulders. I was crushed, annihilated! and exhausted myself in vain attempts to turn in my granite bed. Hours upon hours passed away. A profound and terrible silence reigned around us--a silence of the tomb. Nothing could make itself heard through these gigantic walls of granite. The very thought was stupendous. Presently, despite my apathy, despite the kind of deadly calm into which I was cast, something aroused me. It was a slight but peculiar noise. While I was watching intently, I observed that the tunnel was becoming dark. Then gazing through the dim light that remained, I thought I saw the Icelander taking his departure, lamp in hand. Why had he acted thus? Did Hans the guide mean to abandon us? My uncle lay fast asleep--or dead. I tried to cry out, and arouse him. My voice, feebly issuing from my parched and fevered lips, found no echo in that fearful place. My throat was dry, my tongue stuck to the roof of my mouth. The obscurity had by this time become intense, and at last even the faint sound of the guide's footsteps was lost in the blank distance. My soul seemed filled with anguish, and death appeared welcome, only let it come quickly. "Hans is leaving us," I cried. "Hans--Hans, if you are a man, come back." These words were spoken to myself. They could not be heard aloud. Nevertheless, after the first few moments of terror were over, I was ashamed of my suspicions against a man who hitherto had behaved so admirably. Nothing in his conduct or character justified suspicion. Moreover, a moment's reflection reassured me. His departure could not be a flight. Instead of ascending the gallery, he was going deeper down into the gulf. Had he had any bad design, his way would have been upwards. This reasoning calmed me a little and I began to hope! The good, and peaceful, and imperturbable Hans would certainly not have arisen from his sleep without some serious and grave motive. Was he bent on a voyage of discovery? During the deep, still silence of the night had he at last heard that sweet murmur about which we were all so anxious? CHAPTER 20 WATER, WHERE IS IT? A BITTER DISAPPOINTMENT During a long, long, weary hour, there crossed my wildly delirious brain all sorts of reasons as to what could have aroused our quiet and faithful guide. The most absurd and ridiculous ideas passed through my head, each more impossible than the other. I believe I was either half or wholly mad. Suddenly, however, there arose, as it were from the depths of the earth, a voice of comfort. It was the sound of footsteps! Hans was returning. Presently the uncertain light began to shine upon the walls of the passage, and then it came in view far down the sloping tunnel. At length Hans himself appeared.
