Then he quickly turned his head to the opposite side, deliberately poking his nose into the passing throng, till, with a grunt of recognition, it touched the garment of one who was hurrying on among the crowd. It was evidently a Bedouin, but the wings of his turban were drawn together in front, so that no one could see his face. He responded to the greeting of the white camel, however, by laying his hand upon the creature's nose as he passed. It was a motion which no one noticed, and a moment later he was out of sight. He was following a boy who had led him directly to the arch, where the boy paused, pointed to the elder of the two men standing there, briefly observing: "It is he." The Bedouin paused for a moment, as if struggling to collect his thoughts, then hurrying forward was the next to prostrate himself before the venerable man. As he rose he handed him a package, simply observing: "A message to the Caliph Omar." The great caliph quickly broke the seal and read; then, turning to the bearer, asked sharply, "And who art thou?" "I am Kanana, son of the sheik of the Beni Sads," replied the Bedouin boy, letting the wings of his turban fall apart that Omar might see his face. "A beardless youth!" exclaimed the caliph. "And dost thou know aught of the import of this letter?" Kanana repeated the dying words of the Arab soldier, which had so often escaped his lips as he urged his weary feet toward Mecca. "'Tis even so," replied the caliph. "And how came living man to trust a boy like you to come alone, through the streets of Mecca, with such an errand?" "I came alone with the letter from the oasis at Mount Hor," replied Kanana, straightening himself up, with very pardonable pride, before the astonished eyes of the great caliph. Then he related, briefly, how the letter came into his keeping, and the dangers and escapes of the three long weeks during which he carried it in his bosom; each rising and setting sun finding it a little nearer to its destination. "Thou art a brave youth," said the caliph, "a worthy son of the Terror of the Desert. Would to Allah that every Arab had thy heart, and Heraclius himself, with all the world behind him, could not move the Faithful from their desert sands. And they shall not be moved! No! By the beard of the Prophet, they shall not be moved. Hear me, my son; I will see more of thee. This is no place for conversation, where the wind bloweth into what ears it listeth. One of my slaves shall conduct you to my house. There I will meet you presently. Go, and Allah go with you." Indicating the slave who should take Kanana in charge, the Caliph Omar turned abruptly away and showed the letter to the man with whom he had been conversing. VI KANANA AND THE CALIPH
