"Run away! How could it with the tub sound, not a hole in it? Besides, there bean't no smell, and I don't care who the man is, but if sperits run out, you can smell 'em anywhere."
"I suppose——" began Dick, but his answer was suddenly cut short. From the direction of the passage through which they had come there fell upon their ears a dull rumbling sound, which reverberated for a few seconds, then died away into silence.
The boys stood for a moment in silent bewilderment; then, with a foreboding of evil, Dick hastened back from the cavern along the gallery. In a minute the astounding cause of the noise was explained. The bridge by which they had crossed the shaft was gone. Only the jagged end of it jutted out from the further brink of the chasm. By the flickering light of the candle Dick thought he saw a figure moving backwards through the gallery on the opposite side. He shouted, his voice coming back to him in a hundred echoes. The figure disappeared, if indeed it were not an hallucination: Dick's state of horrified amazement might well predispose him to see visions. He stood on the brink, bathed in chill and clammy perspiration. He realised to the full the situation of himself and his companion. They were trapped in the gallery. Before them was a shaft perhaps hundreds of feet deep; behind, an impenetrable wall.
"I said I'd never do it again, and I never will," sobbed Sam.
"Hoy! hoy!" shouted Dick.
"Yo-hoy, hoy!" Sam repeated in his rougher tones.
But there was no reply; only the mocking, receding echoes.
Dick leant against the wall in dull stupefaction. He had said nothing to his parents about the expedition; he had expressly charged Sam not to speak of it to Reuben. His very caution had proved his undoing. So common was it for him to be all day away from home with Sam that their absence would scarcely be remarked until night, and then, even if it caused alarm, no one would dream of looking for them at the well, still less in one of the passages below. But if Dick's suspicions and inferences were well founded, at some time during the day or night there would be smugglers in one or other of the galleries, and they would surely come within sound of his voice, and not be so base as to refuse to help him. Then it struck him that perhaps such a cry might merely terrify them; that they might believe it to be the utterance of the disembodied spirits that were said to haunt the place. But no; as his first terrors subsided, and he regained his thinking power, a sudden light dawned upon him. The ghosts were the invention of the smugglers themselves! They had taken advantage of ancient tradition and floating rumour for their own purposes, encouraged the credulity of the many in order that the few might preserve the secret of their hiding-place. And then it flashed upon him that his presence near their jealously-guarded lair had been discovered, and that his return had been deliberately cut off, so that they might carry out undisturbed the important operation of which Trevanion and Doubledick had spoken. In that case his incarceration would be temporary, like Penwarden's. As soon as the run had been accomplished, he, like the old exciseman, would be liberated, and the smugglers would gloat over their triumphant strategy.
"How many candles have you got?" he asked suddenly.
Sam rummaged in his pocket, and produced five stumps varying in length.
