palms, rose abruptly from the barren, sun-scorched plain, and, at their foot, stood the dazzlingly-white city of Omdurman, the impregnable and mysterious headquarters of Mahdiism, while beyond, like a silver ribbon winding through the marshes, the Nile glided, half veiled by its thin white cloud of morning vapours. Within the walled and strongly-guarded city was a scene, strange and fantastic. The air, heavy with war rumours, was rent by the deafening strokes of enormous brazen tam-tams, mingling with the loud shouts of dark-faced Jalins, half-naked negro fanatics of the Kunjara and the Dinka, armed cap à pie, ready for battle at a moment’s notice. The excitement, which had increased daily for many months, had risen to fever heat. Throughout the short, hot night, the great nahas—those huge brass war drums of the Khalifa Abdullah, Ruler of the Soudan—had been beaten by relays of perspiring negro slaves, glittering with beads and trinkets, the indescribable monotonous rhythm causing the wildly-excited populace to cry, “Nakelkum!” and “Naklulkum!” as, in the fresh, cool hour, when the Wolf’s Tail—the first brushes of grey light which appear as forerunners of dawn—showed in the heavens, they seized guns, spears and shields, and rushing from their houses across the great square of Abu Anga they congregated in the wide, open space near the Tree of Hadra, where the Raya Zerga, or dreaded black standard of the Khalifa, hung ominous and motionless in the morning air.

The servants of the Merciful are those who walk meekly on the earth, and when the ignorant speak to them, answer, “Peace”; and who pass the night adoring Allah, and standing up to pray unto him, and who say, “O Allah, avert from us the torment of hell, for the torment thereof is perpetual; verily, the same is a miserable abode”; and who, when they bestow, are neither profuse nor niggardly, but observe a just medium between these, and who invoke not another god together with the One Allah, neither slay the soul which Allah hath forbidden to be slain, unless for a just cause. The Dervishes were going forth to battle. On one side of the spacious review ground frowned the castellated walls of the imposing
