With another powerful effort it was lifted the fraction of an inch, and, though it immediately settled back in place, the prisoner knew that the time of his deliverance had come. He could not raise the great slab bodily, but with wedges he could hold the gain of each upward lift. His first aids of this kind were the copper knives that he had brought with him. Then, by a dim light that came through the crevice thus opened, he used his pick to break off fragments of rock, which were slipped under the slab.
It was thus raised and supported an inch at a time, until at length an opening nearly two feet in width was presented. The moment this was effected Peveril drew himself through it, and, with a great sigh of thankfulness for his marvellous escape, lay for some minutes recovering breath after his tremendous exertions and studying his new surroundings.
Although the small amount of light greeting his eyes as he lifted the rock had shown him that he was not to emerge into the open air, he could not help a feeling of disappointment at finding himself still underground. To be sure, he was in a spacious chamber or cavern, he could not yet tell which, illumined by a faintly diffused light that gave promise of some connection with the outer world; but he feared this might prove to be another unscalable shaft, in which case he would be no better off than before—in fact, he might find himself worse off, for he was desperately thirsty and could see no sign of water.
"It would be pretty hard lines if I should be compelled to return to my old well for a drink," he said to himself.
As soon as he had recovered breath, Peveril rose to his feet and began to walk slowly towards that part of the cavern where the light seemed brightest. As he went he looked eagerly on all sides for some trace of the singer whose voice had inspired him with a new hope at the moment of his blackest despair, but no person was to be seen or heard.
At the same time he found abundant proof that human beings had recently visited that place, and would doubtless soon do so again. This was in the shape of boxes, bales, and casks piled against the walls on both sides of the passage. For a moment Peveril was greatly puzzled by these; then, as he recalled Joe Pintaud's conversation regarding smugglers, he concluded that he had stumbled across a depot of goods belonging to those free-traders of the great lake.
"In which case," he said to himself, "I shall surely be out of here within a few minutes; for an entrance for smugglers must mean an exit for prisoners."
This was a sound theory, but, like a great many other theories, one that proved faulty upon practical application, as our young friend discovered a few minutes later.
Directly beyond the packages of goods he came upon a small derrick, set firmly into the solid rock at both top and bottom. It had a substantial block-and-fall attachment, and was swung inward. At this point also a heavy tarpaulin, reaching from floor to ceiling, was hung completely across the cavern.
Cautiously raising one corner of this, Peveril was blinded by such a flood of light that for a moment he was completely dazzled. As his vision was gradually restored he found himself on the brink of a precipice and gazing out over a boundless expanse of water—in fact, over the great lake itself. A narrow ledge projected a little beyond the curtain that he had lifted, and as he hesitatingly stepped out upon it he also instinctively grasped a small cedar that grew from it to steady himself while he looked down.
