The sheik drew back a little. It was a slight but very suggestive motion, speaking volumes to the keen eye of the Bedouin boy. He had been leaning forward before, more than is natural even to one tired out with sitting upon a camel's back. It was as if in his eagerness he was reaching forward to grasp the prize. Now he seemed suddenly to have lost that eagerness. Quickly, Kanana took advantage of the hint. He drew from his bosom the letter of the caliph, sealed with the great seal of Mohammed, which every Mussulman could recognize, and calmly holding it plainly in view, he continued: "The beak of the vulture has whitened, instead of the bones he would have plucked. The tooth of the jackal is broken, and not the flesh he would have torn. Raschid Airikat is neither at Damascus nor Mecca. To-morrow morning he will be at Tayf. He would have you meet him there. Say to him, 'The fool hath eaten his own folly. The veiled messenger of the Prophet, sitting upon the sacred camel, glides with the night wind into the rising sun; for the fire is lighted in Hejaz that at Bashra shall cause the camels' necks to shine.'" A decided change came over the savage face of the Arab sheik. He sat in silence for a moment, then, without a word, drove the prod into his camel. There was a grunt and a gurgling wail, and the tired animal was moving on, followed by all the rest. Kanana and his camel-driver were left alone. When they were well out of hearing the driver prostrated himself before Kanana, touching his forehead to the ground, and asked: "Master, who was that sheik, with all his warriors, and who art thou that they should cower before thy word?" "I am no one to receive your homage. Stand upon your feet!" almost shouted Kanana. "I never saw nor heard of them until to-day." He breathed a deep, quivering sigh, and leaned heavily upon the saddle; for every muscle in his body shook and trembled as the result of what had seemed so calm and defiant. He tried to replace the letter in his bosom, but his hand trembled so that he was obliged to wait. "Thou knewest that he was of the tribe of Raschid Airikat, and that he came from Bashra," said the driver. "I knew nothing," replied Kanana, petulantly, in the intense reaction. "How long have you been a man, well taught in killing other men, not to see what any cowardly shepherd boy could read? Were not their lances made of the same peculiar wood; and their camel saddles, were they not the same, stained with the deep dye of Bashra? Who should come out of the rising sun, with his camel licking the desert sand, if he came not from Bashra? Who should be going toward Mecca at this season, without a burdened camel in his caravan, if he went not to meet his chief for war? Why did Airikat crowd his caravan, day and night, if he expected no one?" "But, master, Airikat is at Mecca, not at Tayf," said the camel-driver.
