He could only grope his way, step by step, through the blinding darkness; cautiously he advanced, but without fear. He tested the ground in front of him as he advanced, with one hand over his eyes and the other on the hilt of his sword. It must, indeed, be a resolutely wicked spirit that would venture to attack him.

Every now and then a bat sped rapidly past him, close to his ears, with a sound like a mocking titter; at other times he trod upon some cold, moving body. But what cared he for these? The deep silence which encircled him was far more terrible than all the voices of hell; and not even the darkness terrified him, for his powerful voice now pierced that subterranean stillness as with a sword.

"I summon thee, thou spirit, whether thou art good or evil, whom Allah permits to hold discourse with living men—I summon thee to speak with me!"

"I am even now beside thee," a voice suddenly whispered. It was low and hollow, just as if the atmosphere of the cavern were speaking.

The stranger made a clutch after the voice, as if his audacious hand would have seized the spirit; but he found nothing. It was a voice without a shape.

"Speak to me!" cried the old man, in a voice that never quavered. "Dost thou know my fate?"

"I know it," answered the invisible voice; "thou art a poor man who hast lost what thou hadst, and what thou now hast is not thine."

"Thou art a senseless spirit," growled the stranger. "Go back to thy tomb and slumber; I will inquire nothing more of thee. Thou dost not even know my present fate; how canst thou know my future? Go back to thy hole, I say, and sleep in peace."

"I know thee," continued the voice, "and I have spoken the truth. Do not they call thee Ali Tepelenti?"

The stranger was amazed. "That is indeed my name," he answered.
