Vainly I tried to recall it. The pressure upon my temples appeared to have crushed and dulled my senses so that any effort to recollect the past was unavailing. My brain seemed electrified by the sudden shock when I had placed the Crescent upon my brow, and now all the past was but a blank, all the present chaotic and incomprehensible. Yet the scene was so familiar, that my inability to recollect where I had before witnessed it was tantalising, and caused me to wonder whether my mind had become unbalanced and the exteriorised image had not been induced by insanity. I dreaded to think it might be so. Yet I now experienced no pain, only a strange, uncontrollable desire to draw nearer. The mountain seemed to act as a magnet, transfixing me, drawing me closer and closer, with a force mystic, but utterly irresistible.

Within me was a violent craving, a sudden longing to search for some unknown person or object concealed there, the truth of which I must at all hazards discover.

Words fell upon my ear; but they were unintelligible. Uzanne was no doubt asking me a question in his eagerness to know what had caused my alarming change of manner, but I heeded not. Swiftly I approached the single mountain rising in its solitary beauty in that vast, lonely land, until suddenly its highest point attracted me, and at last, with an ejaculation of joy, I remembered.

The summit was shaped in the form of a camel’s hump, crowned by three palms that looked at that altitude no bigger than the little finger-joint. The centre tree raised its feathery head higher than those of its companions. Yes, it was the same! The scene that my keen vision now gazed upon was a reproduction, exact in every particular, of the picture that had been revealed by the crystal mirror that Mohammed ben Ishak had allowed me to gaze upon!

In the mirror I had been painfully impressed by the figure of a dying man in the immediate foreground, but the presence of death no longer marred the scene. Pushing forward still nearer, over rough, broken ground, without experiencing any physical fatigue, I distinguished straight before me a dark spot in the side of a great wall of grey rock, just at a point where it rose from the plain to form part of the mountain. Presently I could see that it was the low arched entrance to what appeared to be a cave, and as a sudden desire seized me to investigate it, I pressed forward, overwhelmed by a vivid conviction that within that cavern lay an elucidation of the Great Mystery. Eagerly I approached, until I had come within a leopard’s leap of the gloomy opening, then suddenly some inexplicable power arrested my progress. Struggling to proceed, I fought desperately with the unseen influence that held me back, determined that even though I risked my life, I must enter that rocky portal and search for the knowledge by which I might rescue Zoraida. Her words of piteous appeal urged me forward, but though I exerted all my strength and will, yet I did not advance a single inch further towards my weird and gloomy goal.

Some strange intuition told me that this cavern was the spot I sought, yet, though again and again I strove to shake off the shackles that had so suddenly been cast about me, all effort was in vain, for an instant later my heart sank in despair as the scene gradually dissolved and receded from my gaze, until the mountain grew so distant as to appear the mere misty outline that I had at first witnessed, and I was rudely aroused from a state of dreamy wonderment by hearing Octave exclaim in alarm—

Sapristi! old fellow, I’m beginning to think you’ve taken leave of your senses!”

“No,” I answered, endeavouring to calm myself. “I—I have witnessed an extraordinary scene.”

“Has anything remarkable been revealed?” he anxiously inquired.

“Yes. I have had a strangely vivid day-dream, by which I have been shown the spot whereat to search for the promised explication.”
