After a journey of two long dreary days—days that were to the boy slaves periods of agonizing torture, from fatigue, hunger, thirst, and exposure to a burning sun—the kafila arrived at another watering-place.

As they drew near the place, our adventurers perceived that it was the same where they had first fallen into the hands of Golah.

"May God help us!" exclaimed Harry Blount, as they approached the place. "We have been here before. We shall find no water, I fear. We did not leave more than two bucketfuls in the hole; and as there has been no rain since, that must be dried up, long ago."

An expression of hopeless despair came over the countenances of his companions. They had seen, but a few days before, nearly all the water drawn out of the pool, and given to the camels.

Their fears were soon removed, and followed by the real gratification of a desire they had long been indulging—the desire to quench their thirst. There was plenty of water in the pool—a heavy deluge of rain having fallen over the little valley since they had left it.

The small supply of food possessed by the travellers would not admit of their making any delay at this watering-place; and the next morning the journey was resumed.

The Arabs appeared to bear no animosity towards the young man who had assisted Golah in killing their companions; and now that the black sheik was dead, they had no fear that the former would try to escape. The negro was one of those human beings who cannot own themselves, and who never feel at home unless with some one to control them. He quietly took his place along with the other slaves,—apparently resigned to his fate,—a fate that doomed him to perpetual slavery, though a condition but little lower than that he had occupied with his brother-in-law.

Eight days were now passed in journeying in a direction that led a little to the east of north.

To the white slaves they were days of indescribable agony, from those two terrible evils that assail all travellers through the SaÄra,—hunger and thirst. Within the distance passed during these eight days they found but one watering-place, where the supply was not only small in quantity but bad in quality.

It was a well, nearly dried up, containing a little water, offensive to sight and smell, and only rendered endurable to taste by the irresistible power of thirst.

The surface of the pool was covered nearly an inch thick with dead insects, which had to be removed to reach the discolored element beneath. They were not only compelled to use, but were even thankful to obtain, this impure beverage.

The route followed during these eight days was not along the seashore; and they were therefore deprived of the opportunity of satisfying their hunger with shell-fish. The Arabs were in haste to reach some place where they could procure food for their animals, and at the pace at which they rode forward, it required the utmost exertion on the part of their slaves to keep up with them.

The old man-o'-war's-man, unused to land travelling, could never have held out, had not the Arabs allowed him, part of the time, to ride on a camel. The feat he had performed, in ridding them of that enemy who had troubled them so much—and who, had he not been thwarted in his attack upon the camp, would probably have killed them all—had inspired his masters with some slight gratitude. The sailor, therefore, was permitted to ride, when they saw that otherwise they would have to leave him behind to die upon the desert.

During the last two days of the eight, our adventurers noticed something in the appearance of the country, over which they were moving, that inspired them with hope. The face of the landscape became more uneven; while here and there stunted bushes and weeds were seen, as if struggling between life and death.

The kafila had arrived on the northern border of the great SaÄra; and a few days more would bring them to green fields, shady groves, and streams of sparkling water.

Something resembling the latter was soon after discovered. At the close of the eighth day they reached the bed of what appeared to be a river recently dried up. Although there was no current they found some pools of stagnant water: and beside one of these the douar was established.

On a hill to the north were growing some green shrubs to which the camels were driven; and upon these they immediately commenced browsing. Not only the leaves, but the twigs and branches were rapidly twisted off by the long prehensile lips of the animals, and as greedily devoured.

It was twilight as the camp had been fairly pitched; and just then two men were seen coming towards them leading a camel. They were making for the pools of water, for the purpose of filling some goat skins which were carried on their camel. They appeared both surprised and annoyed to find the pools in possession of strangers.

Seeing they could not escape observation, the men came boldly forward, and commenced filling their goat-skins. While thus engaged they told the Arab sheik that they belonged to a caravan near at hand that was journeying southward; and that they should continue their journey early the next morning.

After the departure of the two men the Arabs held a consultation.

"They have told us a lie," remarked the old sheik, "they are not on a journey, or they would have halted here by the water. By the beard of our Prophet they have spoken falsely!"

With this opinion his followers agreed; and it was suggested that the two men they had seen were of some party encamped by the seashore, and undoubtedly amusing themselves with a wreck, or gathering wealth in some other unusual way.

Here was an opportunity not to be lost; and the Arabs determined to have a share in whatever good fortune Providence might have thrown in the way of those already upon the ground. If it should prove to be a wreck there might be serious difficulty with those already in possession; it was resolved, therefore, to wait for the morning, when they could form a better opinion of their chances of success, should a conflict be necessary to secure it.
