Zoraida’s strained voice broke the silence.

“Blessed be he to whom the lifetime of the ruby is as the lifetime of the rose. O thou of exalted dignity, behold me, the least and least worthy of all them that praise the One worthy of praise. May I never endure prosperity as a gift from the accursed, for I seek the Secret of the Crescent, and ask of the One of unbounded favour and infinite bounty that which thou alone canst reveal.”

Again the marabout faced the altar, again he made passes over the fierce fire. The censer, still kept swinging by some unseen power, emitted a column of thick smoke, the odour of which, at first sulphurous, then sensuous and overpowering, caused me to feel intolerably drowsy. Then suddenly, with a noise as loud as the firing of a pistol, a great rent appeared in the stone front of the altar, as the slab of jasper broke in twain and a portion fell to the ground.

“Lo! it is at last revealed!” cried Zoraida, turning to me excitedly. “Life remaineth unto us! The poison will take no further effect, since we shall possess the Great Secret.”

Bowing to earth, the marabout approached close to the altar, and, dropping upon one knee, placed his hand in the aperture that had been so suddenly created. From the hole he drew forth a semicircular box of time-stained leather, about twelve inches across, and, opening it carefully, took therefrom a piece of rusted iron, shaped in the form of a crescent, about two inches wide in the centre and tapering to horns at each end. Its form was almost like a sickle, covered with strange hieroglyphics deeply graven, and it was about a quarter of an inch in thickness in every part, with a notch in the centre, as if another portion that had once been welded to it had been broken away.

Zoraida, still kneeling, eagerly watched the ghastly figure, who, bowing once again, held the strange object over the flame until it became heated.

“Beseech of the Power, O Sidi Mammar ben-Mokhala, if the secret may be wholly revealed unto the Roumi,” she said in a loud, clear voice.

Again the corpse that had been awakened from its sardonyx casket bowed and raised its hands aloft in obedience to her request, as we all three watched the censer. The thin column went slowly up, but the puff of thick smoke—that seemed to be regarded as a sign of the affirmative—was not emitted. Yet again the marabout bowed in silent intercession, but, though we waited for some minutes, no reply was vouchsafed.

“Thou art not a True Believer, O Cecil,” Zoraida said, in bitter disappointment. “The Great Secret, although revealed unto me, is withheld from thy knowledge. Alas that it should be so! Truly I bear the yoke of misfortune and taste the venom of grief.”

“Of what use is the Crescent?” I said, regarding with curiosity the rusted relic in the bony hand of the aged marabout.
