They all turned out as best they could, however, for the savage black slave of the great caliph, and by keeping close behind him Kanana always found an open space where he could walk without fighting for room.

It was almost the first experience of the Bedouin boy in real city life, and the very first time that his bare feet had ever touched the beaten sand of the unpaved streets of his most sacred Mecca.

He turned from the arch, however, without once glancing at the black-curtained Caaba, the Beitullah, or House of God, toward which three times a day he had turned his face in reverent devotion, ever since he had learned to pray.

He followed the black slave onward through the streets, without so much as looking at the walls of the houses that crowded close on either hand.

He had fulfilled his vow. The packet he had sacredly guarded through many a hardship and danger and narrow escape was safely delivered. Now he was free to carry on the work for which he left the perch and the birds in the grain-field of the Beni Sad.

Sometimes he thought of the black slave before him, and wondered if, after all, he was quite free. And the thought troubled him.

It seemed as though long years had passed since the day when his father met him with the news of Raschid Airikat's capture of his brother. He had suffered privations enough for a lifetime since then. More than once his life had hung by a slender thread. He could hardly imagine himself again sitting up on the perch, frightening the birds away, his life had so entirely changed; his determination to keep the vow he made his father had grown stronger every day; only he realized more the magnitude of the task he had undertaken; and he appreciated his father's words: "Thou wisp of straw before a fire! Thou reed before a whirlwind!" Still he gathered hope, because he was beginning to understand himself.

The dangers and hardships of one enterprise he had met and overcome, and under the very shadow of the Caaba, the great caliph of Mecca had called him brave.

Now he was eager for the next. There was no vital need of another interview with the caliph, and Kanana thought that if he could only escape from the black slave, by darting into a crowded alley, he could go at once about his own important business.

For the first time Kanana looked about him. At the moment there was no opportunity, and while he watched for one, the slave turned suddenly into a great gate, crossed a court paved with limestone, lifted a reed curtain, entered one of the most substantial stone structures of Mecca, and indicated to Kanana the apartment in which he was to wait for the caliph. It was too late to escape. With all the patience and dogged submission to destiny so strongly developed in the Bedouin, Kanana sat down upon a rug. There were luxurious ottomans about the room, and divans taken from the palaces of Persian princes, but the Bedouin boy preferred the desert seat. Much as though he were still upon the perch, he laid his staff beside him and buried his face in his hands. The magnificence in this chamber of Omar's official residence only disturbed his thoughts.
