“And upon thee may the Omniscient One ever shower his blessings. May the Prophet be thy protector,” I cried in response.

But he had cried, “Yahh! Yahh!” to his ass, and the beast, thus urged forward, was jogging rapidly away on the first stage of his long journey northwards.

My pledge to Azala, and her earnest words that recurred to me, alone prompted me to continue my journey. A wanderer in desert and forest, with the soul of the true-born Bedouin, ever restless, ever moving, I had seen much of that half-civilised life led by the people beyond the influence of the Roumis. In London, cooped up amid the so-called civilisation of the English, their streets and shops, their wonderful buildings, and their women with uncovered faces, I cared nought for study, longing always for the free life of the plains that knows not law. Even of Algiers I had tired, and chosen a wandering existence of my own free will, exiling myself even from my Arab clansmen, and becoming a soldier of the great Mahdi, who, with his contemptuous disregard for human life, had spread the terror of his name in letters of blood. Yet through it all the one mystery of my life, the indelible mark upon my breast, had remained unsolved. Nay, its mystic significance had increased, for having looked with love for the first time upon a woman, I had found that she also bore the mystic device.

It was to endeavour to penetrate this mystery, to discover the spot, the reflection of which had appeared often in Kano as a mystic cloud-picture, that I had set out, and I became filled with a determination to strive towards it as long as Allah gave me breath. Forward I would fight my way, and plunge without fear into the trackless, unknown regions of which Mohammed had spoken, and question the people of the various countries eastward, to ascertain if any could direct me to where stood the gloomy Rock of the Great Sin.

Accompanied by the ugly dwarf, whose conversation was always quaint, and who entertained me with tales of the prowess of his people, as numerous and varied as those stored within the brain of a Dervish storyteller, we travelled onward day by day, week by week, up the swiftly-flowing Benue, where manioc, pumpkins, yams, kola nuts, colocasia, rijel, sugar-canes, and the helmia, whose tuberous root resembles the potato in taste and appearance, grew in great abundance through the fertile Foulde country, beneath the high granite crags of Mount Yarita, and at last, leaving the river, a mere stream so small that one could stand with a foot on either bank, we made a long and toilsome ascent, at length finding ourselves upon a great, sandy plateau devoid of herbage. Guiding our course by the sun, we struck one day at dawn due eastward, over great dunes of treacherous shifting sand, into which the feet of our asses sank at every step, rendering progress very slow and extremely difficult.

For a long time we were both silent; it was as much as we could do to advance with our animals halting and turning obstinately at every step. Suddenly I was startled by Tiamo crying aloud in dismay, “Balek! Elgueubeli!” (Take care! the sandstorm).

Then, for the first time, I realised that a strange darkness had fallen, that the morning sun had become utterly obscured by a dense, black cloud, and gigantic sand columns were whirling over the plain at furious speed. Next moment, a howling, tearing wind swept upon us with the force of a tornado. As I twisted my ragged haick quickly about my face, to shield my eyes and mouth, my ass, apprehensive of our danger, veered round with his hindquarters to the tempest. I leaned towards the ass’s neck, and felt him tremble beneath me.

Then, in an instant, I received a terrific shock; it seemed to me that a camel’s pack of sand had fallen all at once upon my head.
