As we retraced our steps he poured upon me nauseating adulations, declaring me to be the most valiant sheikh in the Great Desert, and using the most extravagant simile of which the Arabic tongue is capable, a fact which in itself filled me with increasing suspicion. Suddenly, however, as we reached the chamber where flowed the cooling spring, the truth was made plain. As he opened the door two officers of the French, in linen garments and white helmets, who had apparently been lying in wait, pounced upon me, uttering loud cries of triumph.

The old white-bearded recluse—may Allah burn his vitals—had betrayed me. He had held me, and sent word to the Franks to come and capture their prize—Ahamadou, the chieftain of the Azjar. But in an instant I, upon whose head a price was set, drew my blade and defended myself, slashing vigorously right and left, succeeding at last in escaping down the dark winding passage through which we had just passed. Forward I dashed through room after room, upsetting some of the tables in my mad rush, while behind me were the white-faced officers with drawn swords, determined to take me alive or dead. Well I knew how desperate they were, and in that instant believed myself lost. Yet, determined to sell my life dearly, it flashed across my mind that rather than suffer the ignominy of being taken in chains to Algiers, the infidel city, and there tried by the tribunal as others had been, I would cast myself into the fathomless pit.

I sprang towards the small, low door, but at first could not open it. In a few moments the crafty Ibn Batouba, with the Franks, gained the spot; but I had already unlocked the door and flung it open. Then, just as they put out their hands to seize me, I swung aside, lifted my knife, and struck my evil-faced betrayer full to the heart.

With a piercing shriek he fell forward over the door lintel, and his lifeless body rolled into the awful chasm, while at the same instant I gave a bound, and with a cry of defiance, leaped down into the darkness after him.

I felt myself rushing through air, the wind whistling in my ears as deep down I went like a stone in the impenetrable gloom. Those moments seemed hours, until of a sudden a blow on the back knocked me half-insensible, and I found myself a second later wallowing in a bed of thick, soft dust. Instantly it occurred to me that because this carpet of dust deadened the sound of things pitched into the chasm, the belief had naturally arisen that it was unfathomable. I rose, but sank up to the knees in the soft sand, which, stirred by my fall, half-choked me. Far above, looking distant like a star, I saw the light of a torch. My infidel pursuers were peering into the fearsome place in chagrin that I had evaded them. The air, however, was hot and foul, and I knew that to save my life I must be moving; therefore, with both hands outstretched, I groped about, amazed to discover the great extent of this natural cleft in the earth, formed undoubtedly by some earthquake in a remote age.

Once I stumbled, and bending, felt at my feet the still warm body of my betrayer—may Eblis rend him. I drew my jambiyah from his breast, and replaced it in its sheath. Then, tearing from his body the silken gauze which formed his girdle, I fashioned a torch, igniting it after some difficulty with my steel. Around me was only an appalling darkness, and I feared to test the extent of the place by shouting, lest my pursuers above should hear. So forward I toiled in a straight line, floundering at every step in the dust of ages, until the cleft narrowed and became tunnel-like with a hard floor. I stooped to feel it, and was astounded to discover that the rock had been worn smooth and hollow by the tramp of many feet.

Besides, the air had become distinctly fresher, and this fact renewed courage within me. At first I felt myself doomed to die like a fox in a trap; but with hope reawakened there might, after all, I thought, be some outlet.

Of a sudden, however, there arose before me a colossal female figure seated on a kind of stool, with features so hideous and repulsive that I drew back with an involuntary cry. It was a score times as high as myself, and as I hold my torch above my head to examine it, I saw it was of some white, semi-transparent stone of a kind I had never before beheld. The robes were coloured scarlet and bright blue, and the face and hands were tinted to resemble life. One hand was outstretched. On the brow was a chaplet of wonderful pearls, and on the colossal fingers, each as thick as my own wrist, were massive golden rings which sparkled with gems. But the sinister grinning countenance was indeed that of a high-priestess of Eblis.

In amazement I held my breath and gazed about me. Around the sides of the cavern were ranged many other smaller female figures, seated like the central one, and the face of each bore a hideous, repulsive grin, as if in mockery of my misfortunes. Before the great central colossus was a small triangular stone altar, upon which was some object. I crossed, and glancing at it found to my dismay that it was a beautiful and very ancient illuminated manuscript of our holy Korân. But through it had been thrust a poignard, now red with rust, and it had been torn, slashed, and otherwise defiled.

The truth then dawned upon me that this noisome place into which I had plunged was actually the abode of the ancient and accursed sect who worshipped Eblis as their god.
