“Enough!” cried Azala, horrified at what seemed a revolting augury of her own end. “See! the brute hath struck off her head!” And shuddering, she gazed around the apartment with a look of abject terror, her haggard features in that moment becoming paler and more drawn.

“Heed it not as ill-potent,” I said, smoothing her hair tenderly, and endeavouring to remove from her mind the horrifying thought that she might fall under the doka of the Grand Eunuch. “The mystic Prism of Destiny showeth much that is grim, distorted and fantastic. The eventuality is only resolved so that we may arm ourselves against the Destroyer.”

But, apprehensive of her fate, she shook her head sorrowfully, saying in low, harsh tones, “When on the previous occasion I gazed into the prism a similar scene was conjured up before me, only the woman was then at his knees imploring mercy, while he, with doka uplifted, laughed her to scorn. Now, see the end! Her head hath fallen!”

Again I turned to ascertain what next might be shown in the revolving crystal, the mystery of which was ever-increasing, but it had ceased to move. Eagerly I bent, gazing into its green, transparent depths in order to discover whether the strange scenes were mere optical illusions. Only for a second was I permitted to gaze, but in that brief moment suspicion seized me that I had been imposed upon. Whether Azala actually believed that forecasts of the future could be witnessed in the crystal, or whether she was only striving to impress me by regaling me with an exhibition of the mystical, in which all women of her race delight, I know not; but I was sceptical and became convinced that the pictures had been conjured up by mechanical contrivance, and that the illusions—probably the stock-in-trade of some court necromancer—were performed by ingenious but hidden paintings or tableaux.

By this discovery I was much perturbed, for it was remarkable that, on witnessing the scenes, Azala’s surprise and agitation were natural and unfeigned, and this act led me to the conclusion that, believing in spells and amulets, she was also ready to place faith in any extraordinary marvel that she might gaze upon.

It was common knowledge, I remembered, that the women of Sokoto were extremely superstitious, believing as implicitly in the sayings of their astrologers as we, of the North, believe in the efficacy of representations of the hand of Fathma of Algiers nailed over our doors to avert the Evil Eye. Was this chamber the sanctum of some seer whose duty it was to forecast the good or evil fortune of the doves of the harem?

I turned, and was about to address to her some question directed towards fathoming the secrets of this cunningly-contrived instrument of psychomancy, when suddenly she drew aside the curtain from a lattice near, uttering an exclamation of mingled surprise and dismay.

Rushing towards her, I looked out, and the sight riveted my gaze in abject amazement.

The dawn had already spread with delicate tints of pink and rose, but in the northern sky a strange, inverted picture was presented with such clearness and vividness of outline that every detail is still as fresh in my mind as it was at the moment I witnessed it.

The picture was produced not by the chicanery of any necromancer, but by Nature herself. It was that strange, puzzling illusion—the mirage. So weird and wonderful was it that, even though I had seen many similar pictures in the heavens during my journeys over the plains, I gave an involuntary exclamation of amazement.
