"Nay, nay," said Al-Abukar, shading his eyes with his hand, as he looked out across the desert, "'tis only the sand caught up in a swirl of the wind. Be not impatient, my son," he continued, "thou wilt tire both thyself and the little mare if thou dashest needlessly about, and neither of you will be able to greet thy little friend with the proper spirit." Hamid and Zuleika, the little pony, both tossed their heads at the idea of such a thing; and no wonder! for Hamid belonged to the Beni-Harb, one of the best and bravest of the Bedouin tribes. As for Zuleika, she had come from the Nijd Desert, where the finest Arabian horses are bred, and it was said she was a descendant of the famous horse of Saladin, the great Arab ruler of olden times. The pony's coat was rough and shaggy, and not smooth and glossy as we like to see; but Hamid could soon show you all her good points. The small head, with its thin pointed ears, wide nostrils, and large eyes, and the proud arch of her neck and the network of muscles on her wiry legs all showed that she was an Arabian horse of the bluest blood. Hamid and his father had ridden out into the desert to meet little Rashid, a young friend of theirs who lived in the city of Medina. Rashid had been ill, and it was not easy to get well in the hot, narrow, ill-smelling streets of an Arabian city; so his father was bringing him to stay some months with Hamid, that he might live in a tent and breathe the dry, pure air of the desert, drink plenty of camel's milk, and thus become well and strong. "The People of the Walls," as the Arabs of the desert call the folk who live in the towns, often send their children to live for awhile in the "Black Tents" in the desert, that they may grow up strong and healthy and become hardy and brave like the Bedouins themselves. The Bedouins, the real desert Arabs, are among the bravest and most courageous people in all the world. The "Black Tents," the habitations of the Bedouins, are so called because they are made of a material very sombre and dark in colour. "Could we not ride farther out to meet our friends?" asked Hamid, for both he and Zuleika were becoming more and more restless. "I fear we should miss them, for I know not whether they will come over the ridge or by the road up the valley," said his father. Just at this moment one of the Bedouins called out: "Do I not see the dust from the camels' feet over yonder?" "Ah, it is truly they; haste and we will give them welcome." So saying, Al-Abukar spurred his horse forward, and Hamid and his pony were not far behind. Together they flew like the wind over the sand and rocks. As they came in sight of their friends, they shouted out their names, at the same time throwing their lances into the air and catching them again, and firing off their guns in real circus fashion. You would think that all this would frighten one's friends to death, but this is only the polite Bedouin way of welcoming any one.
