The music of the sand, as it flew from the camel's feet and fell like hail upon the dry leaves of the desert shrubs, was a delightful melody, and hour after hour they held the rapid pace; over low hills and sandy plains; past the mud village and the well that marks the resting-place for caravans, a night's journey from Mecca, without a sign of halting; and on and on, the dromedary always just so far behind, always doing his best to come nearer. If by urging he was brought a little closer to the camel, the driver heard that low word, "Faster!" and in spite of him the camel gained again. Would he never stop? The sounds from behind had long been lost when, far in advance, appeared the regular caravan from Tayf. They approached it like the wind. Only the mystic salaam of the desert was solemnly exchanged, then, in a moment, the trailing train as it crept westward was left, disappearing in the darkness behind them. When it was out of sight the white camel suddenly changed its course, turning sharply to the north of east and striking directly over the desert, away from the hills and the beaten track to Tayf which he had been following. The driver could not imagine that such a man as sat upon the white camel had lost his way. He silently followed till they passed a well that marked the second night's journey from Mecca toward Persia. The driver and dromedary would very willingly have stopped here; but the camel glided onward before them through the changing shadows of the night, as though it were some phantom, and not a thing of flesh and blood. By dint of urging, the driver brought the dromedary near enough to call: "Master, we are not upon the road to Tayf." "No," said Kanana, but the camel still held his course. Driven to desperation, as the eastern sky was brightening, the driver called again: "Master, you will kill the camel!" "Not in one night," said Kanana; "but if you value your own life, come on!" Faster still and faster the white camel swept toward the glowing east, but the dromedary had done his best. He could not do better. More and more he fell behind, and in spite of every effort of the driver, the pride of the caliph was beaten. Fainter and fainter grew the outline of the white camel against the morning sky, ever swinging, swinging, swinging, over the silver-gray sea, with a motion as regular and firm as though it had started but an hour before. As the red disc of the fiery sun rose out of the desert, however, the driver saw the camel pause, turn half about, till his huge outline stood out in bold relief against the sky, and then lie down.
