The biggest desert in the world is in Africa, and is called the Sahara. It is almost as large as the Atlantic Ocean, but instead of water it is all sands and rocks. Like the ocean, it is visited with storms; dreadful gales, when the wind scoops up thousands of tons of sand and drives them forward, burying and crushing all they meet. And it has islands, too—small green patches, where springs bubble through the ground, and ferns and acacias and palm-trees grow. When a traveler sees one of these fertile spots afar off, he feels as a tempest-tossed sailor does at sight of land. It is delightful to quit the hot, baking sun, sit in shadow under the trees, and rest the eyes, long wearied with dazzling sands, on the sweet green and the clear spring. Oases, these islands are called. Long distances divide them. It is often a race for life to get across from one to the other. Sometimes people do not get across! In 1805, a caravan of 2,000 persons died miserably of heat and thirst in the great desert, and the sand covered them up. Do you wonder at my saying that the desert eats men?

Now, you will be puzzled to guess what sort of ship it is which swims this dry ocean. It is the camel—an animal made by God to endure these dreadful regions, in which no other beast of burden can live and travel. I dare say many of you have seen camels in menageries. They are ugly animals, but very strong, swift and untiring. With a load of 800 pounds on his back, a camel will travel for days at the rate of eight miles an hour, which is as fast as an ordinary ship can sail. More wonderful still, he will do this without stopping for food or water. Nature has provided him with an extra stomach, in which he keeps a store of drink, and with a hump on his back, made of jelly-like fat, which, in time of need, is absorbed into the system and appropriated as food. Is it not strange to think of a creature with a cistern and a meat-safe inside him? A horse would be useless in the desert, where no oats or grass can be had; but the brave, patient camel goes steadily on without complaint till the oasis is reached: then he champs his thorn bushes, fills himself from the spring, allows the heavy pack to be fastened on his back again, and is ready for further travel.

Now you know what sort of a ship it is that I am going to tell you about. It was a camel, named Solimin. He was of a rare and valuable breed, known as "herie," or coursers, because they are so much swifter than ordinary camels. Solimin's master, Ahmed, was a poor man. He never could have afforded to buy a full-grown camel of this rare breed; and Solimin had become his through a piece of good fortune. When a little foal, Solimin was found in a lonely place in the desert, standing over the dead body of his mother, who had fallen and perished by the way. Led to the brown tent which was Ahmed's home, the orphan baby grew up as a child of the family, lay among the little ones at night, and was their pet and plaything all the day. The boys taught him to kneel, to rise, to carry burdens, to turn this way and that at a signal. The girls hung a necklace of blessed shells around his neck, saved for him the best of the food, sang him songs (which he was supposed to enjoy), and daily kissed and stroked his gentle nose and eyes. As he grew big and strong, the pride of his owners grew with him. Not another family of the tribe possessed a herie. Once and again, Ahmed was offered a large price for him, but he rejected it with disdain.

"Would I sell my son—the son of my heart?" he said. "Neither will I part with Solimin. By the Prophet, I swear it."

Of all the dwellers in the brown tent Solimin loved best Ahmed himself, and his eldest son, Mustapha. With them he was docile as a lamb; but if strangers drew near, or persons he did not like, he became restive and fierce, screamed, laid back his ears, and kicked with his strong hind legs. A kick from a camel is no joke, I can tell you. All the desert guides knew Solimin, and, for his sake, Ahmed was often hired to accompany caravans. Nay, once, at Cairo, Solimin was chosen to carry the sacred person of the Khedive on a day's excursion up the Nile bank, which event served the tribe as a boast for months afterward.

It was the year after this journey to Cairo that Ahmed met with a terrible adventure. He and Mustapha, making their way home after a long journey, had lain down to sleep away the noontide hours, according to the custom of desert travelers. Their camels were tethered beside them, all seemed secure and peaceful, when, sudden as the lowering of a cloud, a party of Arabs, belonging to a wild tribe at enmity with all men, pounced upon them. Ahmed and his son defended themselves manfully, but what could two men, surprised in sleep, do against a dozen? In five minutes all was over. The assailants vanished in a cloud of dust, and Ahmed, who had been struck down in the rush, recovered his senses, to find camels, baggage, belt, money, everything gone, and Mustapha wounded and motionless on the earth beside him.

Ahmed thought him dead. They were alone in the desert, a hundred miles from home, without food or water, and with a groan of despair he sat down beside his son's body, bowed his head, and waited until death should come to him also. An Arab believes in fate, and gives up once for all when misfortune occurs.

But Mustapha stirred, and Ahmed at once sprang up. There was nothing he could do for the poor boy, except to chafe and rub his hands; but this was something, for presently Mustapha revived enough to speak.

"Are they gone?" he asked.

"Yes, the accursed ones, they are gone, with all our goods and with Solimin! The Prophet's curse light upon them!" And passing from despair to fury, Ahmed threw sand upon his head, and flung himself on the ground in helpless rage. Mustapha joined in with groans and lamentations.
