"We felt that if we were once heard, and if hard work could do it, that our mates would save us yet; and we encouraged one another as well as we could. But presently the oil in our lamps gave out, and we were left in darkness; and then our hope grew faint indeed. We had knocked for four-and-twenty hours unintermittingly without any reply. We did not cease, however, to discuss the possibilities of escape. We knew that all was being done for us above-ground that could be done; that the surveys of the mine were well executed; and that it was known exactly where we were, if we were alive at all. There were more than a hundred men employed in the lower workings, and it was a certainty that not one of them could have escaped death; the attention, therefore, of the engineers would be concentrated upon those parts of the mine that might possibly be left above water." "On the second night of our imprisonment we heard a distinct reply to our signal; the old man who was of our company began to weep for joy, though he was doomed, as it turned out, poor soul! never to see the light. 'We shall be saved,' he said; 'do not fear.' We knocked again, and again the reply was heard--they had found us out, and would never relax their efforts to save us. 'God bless them!' said we all. We laid our ears close to the rock, and presently heard the strokes of the pick, but not very distinctly. When the other said he was afraid the rock was thick, the old man cried out: 'No, it was not that; it was because we were dull of hearing.' The fact was, that the seam was not only thick, but very hard. It was strange, indeed, though sounds are easily transmitted through rocks of considerable thickness, how our feeble taps had been heard at all. Day after day, and each day a black night, went on; every hour was to be the last of our captivity, according to the old man; as for me, I was almost worn out, and heavy with sleep, but he was in constant motion, knocking and listening. Then suddenly we heard a splash in the water beneath us--he had lost his balance, slid down the inclined plane, and been drowned. He never stirred a limb nor uttered a cry. His fate discouraged and alarmed us two survivors exceedingly. If help was coming, we now felt it would never come in time. We dug into the shale with the handles of our lamps and with our fingers, to make our position more secure. We did not venture to speak of our late companion's fate to one another. Horror overwhelmed us, so enfeebled had we become through famine and fatigue. We had devoured our leather belts, and even crumbled the rotten wood of the timber-props in water, and eaten that; but we were now consumed by thirst, which we dared no longer quench. We were afraid to venture down as before for the water in which the old man had sunk to death; and it was that which had kept us alive." "Don't forget about how you made a bucket of your boots, Sol," suggested Trevethick, gravely.
