Howa-thâ!” she cried. “I will prove further that there is no life;” and, raising the knife in her hand, she plunged it into the breast of the corpse.

“Art thou satisfied that he is really dead?” asked Zoraida grimly.

“Yes,” I answered, shuddering, for my whole surroundings in that subterranean Chamber of the Serpents were so uncanny, that I began to long for light and fresh air. Was she performing all these strange rites merely for the purpose of impressing and mystifying me; or was she an enthusiastic devotee of some secret sect of Al-Islâm? To poison one’s self before invoking the aid of the occult seemed an extraordinary proceeding, and the whole of the rites were so curious, that, fascinated as I was by the mysticism of the East, I regarded them with the most intense interest.

“At the Shrine of Darkness death loseth its sting,” she said. “To communicate with Eblis, the Terrible, it is necessary that one who is already a dweller in the Garden of Delights shall return to life and assist us. Here, in this charnel-house, the abode of death and of the serpents, strange knowledge may be imparted; but ere we proceed further, the sacrifice must be made.”

Snatching up a viper that lay coiled upon one of the divans, she grasped it dexterously near the head, and, walking to the altar, held it for a few moments above the burning brazier, repeating some weird word’s, then, as the reptile squirmed under the pain, she dropped it upon the burning coals.

Flinging herself upon her knees, with her hands outstretched above her head, she again invoked the aid of the mysterious Power. Pushing back her hair, that had fallen over her shoulders, she again rose, and, coming towards me, exclaimed—

“Watch, and I will reveal unto thee the terrible power of Eblis that hath been imparted unto me. Cathâ!”

She looked more haggard than before. The strain upon her nerves was evidently awful. Taking my hand, she led me back to the sarcophagus, repeating some words in such a low tone as to be inaudible. Suddenly she dashed forward, and with her right hand made mysterious passes over the face of the corpse.

“Sidi Mammar ben-Mokhala, chosen of the Merciful. Peace! Again I call upon thee, holy man of the Faith, tenant of the tomb of dignity and light of the eyes of the discerning, to assist this Roumi to the sight of the Crescent of Wonders, for none save myself knoweth aught of the way thither. Blessing upon thee, and great peace on those who went before thee!”
