His life as a shepherd had, after all, not been wasted. "Faster," said Kanana, touching the camel's neck with his shepherd's staff, and without even the usual grunt of objection, the animal obeyed. The sand began to fly from his great feet as they rested upon it for an instant, then left it far behind; the Bedouin boy sat with eyes fixed on the path before him, and his head bent so that he could catch the faintest sounds coming from behind. The mantle that had covered his face fell loosely over his shoulder. The dromedary lost a little ground for a moment, but gathering himself together, easily made it up. The driver was too sure of the final result to urge him unduly at the start. Soon enough the white camel would rebel of his own accord, and till then it was quite sufficient to keep pace with him. The sound of horses' hoofs became sharper and more distinct, and Omar's messenger knew that the five shadows were being pressed to greater speed, and were drawing nearer. "Faster!" said Kanana, and the white camel broke into a run, swinging in rapid motions from side to side, as two feet upon one side, then two on the other were thrown far in front of him and, in an instant, left as far behind. Still the dromedary made light work of keeping close upon his track, evidently realizing what was expected of him; but the driver saw with dismay how quickly the camel responded to the word of his rider, how easily the man sat upon the swaying back--how carefully he selected the best path for the animal, and how skillfully he guided him so that he could make the best speed with the least exertion. Many a night Kanana had run unsaddled camels about the pastures of the Beni Sads, guarding the sleeping sheep and goats, little dreaming for what he was being educated. The sound of horses' hoofs grew fainter. They were losing ground, but now and then the listening ear caught the sharp cry of an Arab horseman urging his animal to greater speed. "They are in earnest," muttered the Bedouin boy, "but they will not win the race." "Faster!" said Kanana; the camel's head dropped till his neck lost its graceful curve, and the great white ship of the desert seemed almost flying over the billowy sand. For a moment the dromedary dropped behind. The driver had to use the prod and force him to the very best that was in him, before he was able to regain the lost ground. The sound of hoofs could no longer be heard, and Kanana was obliged to listen with the utmost care to catch the faintest echo of a distant voice. "They are doing their best and are beaten, but we can do still better," he said to himself with a deep sigh of relief, as he watched the desert shrubs fly past them in fleeting shadows, scudding over the silver-gray sand.
