"We are at the bottom of the steps," said the echoing voice in front of Oliver, and the next instant he felt the startling jar of missing a step. Although the blackness was impenetrable, it seemed to Oliver that they had now reached a large room, for their footsteps echoed with a hollow sound, as though from high walls and a vaulted roof. His guide laid a hand upon his arm, and at the signal he stopped. Presently he heard Gaspard fumbling and rustling, and the next moment a shower of sparks were struck with flint and steel. As the tinder blazed under his breathing, Oliver saw that Gaspard leaned over a small brazen vase that sat upon the ground. He lighted a match and dropped it into the vase, and instantly a vivid greenish light blazed up, dancing now higher, now lower, and lighting up all the surrounding space. Then Oliver saw that he was indeed in a high, vaulted, cellar-like apartment, without window or other entrance than that through which they had come. In the centre of this vaulted space, and not far from where they stood, was a trap-door of iron, to which was attached an iron ring; a wide, heavy iron bar, fastened to the floor at one end by a hinge and at the other by a staple and padlock, crossed the iron plate, and locked it to the floor. Again Gaspard drew out the two keys, and fitting the second into the padlock, gave it a turn. The padlock gaped. He loosed it from the staple, and swung back the iron bar, creaking and grating upon its rusty hinge; then, clutching the ring in the lid of the trap, he bent his back and heaved. The iron plate swung slowly and heavily up, and as Oliver looked down, he saw a glimmering flight of stone steps that led into the yawning blackness beneath. [Illustration: "HE LIGHTED A MATCH AND DROPPED IT INTO THE VASE."] Gaspard reached down into the square hole, and after fumbling around for a moment, drew forth an ancient rusty lantern with the end of a half-burnt candle still in it, which he proceeded to light. Then he who was the master spoke again. "Oliver, my child," said he, smoothly, "down below there are three rooms; in the farthermost room of the three is a small stone pillar, and on it are two bottles of water. Bring them up here to me, and I will make you so rich that you shall never want for anything more in this world." "Am I--am I to go down there alone?" said Oliver, hoarsely. "Yes," said the other, "alone; but we, Gaspard and I, will wait here for you." "And what then?" "Then I will make you rich." Oliver looked into the face of the other. In its cold depth he saw something that chilled his heart to the very centre. He turned, and, leaning forward, gazed stupidly down into the gaping hole at his feet; then he drew back. "My God!" he said, "I--cannot go--down there alone." "But you must go," said the other. "I--I cannot go alone," said Oliver again.
