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.
