Stasch smiled again.

“A real gentleman does not bark when greeting you or when saying good-by, unless he be a dog, and Saba is a dog.”

Soon afterward a sad look came in the boy’s eyes; he sighed again and again, and then got up from the stone on which they were sitting and said:

“The worst is that I can not free you.”

Nell stood on tip-toe and put her little arms around his neck. She wanted to console him, wanted to murmur her thanks close to him, with her little face on his cheek; but as she could not find appropriate words, she merely clung more lovingly to his neck and kissed him on his ear. Saba, who was always late—not so much because he could not keep step with the camels as because he chased jackals on the way and barked at the hawks crouching on the rocks—was seen running up and making as much noise as usual. As soon as the children saw him they forgot everything, and notwithstanding their sorry plight, they began caressing him and playing with him as usual, until the Arabs stopped them. Chamis gave the dog food and water, and then they all remounted and departed in great haste, going farther toward the south.

This was the longest ride they had taken at one stretch, eighteen hours with but one short halt. Only riding-camels, who have a considerable supply of water in their stomachs, can stand such a journey. Idris did not spare them, for he feared that the pursuers were surely at his heels. He realized that they must have started long ago, and conjectured that the two engineers were at the head of these expeditions and would waste no time. Danger threatened them from the river-side, for it was quite certain that the sheiks on both banks of the Nile would form scouting parties to go into the interior of the desert, and would hold back all travelers going south. Chamis felt certain that the government and the engineers had offered a great reward for their capture, and that consequently the desert was probably filled with searchers. The only way to avoid these would be to go as far west as possible; but to the west lay the great oasis of Chargeh, where there was a telegraph. Besides, were they to go too far away from the river the water would give out after a few days and they would die of thirst. There was also the question of provisions. It is true that in the two weeks preceding the kidnapping of the children the Bedouins had hidden provisions of maize, zwieback, and dates in secret places known only to themselves, but these secret places were four days’ journey from Medinet. Idris was terror-stricken at the thought that when the food gave out some of them would have to go to the villages on the river-banks to buy provisions, and that, on account of the strict watch and the rewards offered by the village sheiks for the capture of the fugitives, these might easily fall into the hands of the villagers and betray the whole caravan. The situation was indeed difficult, almost desperate, and Idris saw more clearly every day what a wild scheme he had undertaken.

“If we had only passed Assuan,” said he to himself, his heart full of fear and despair. He did not believe Chamis, who declared the Mahdi’s warriors had already advanced as far as Assuan, for Stasch disputed this, and Idris had long noticed that the white boy knew more than all of them. However, he supposed that beyond the first cataract, where the people were more savage and less under the influences of the English people and the Egyptian Government, more secret believers in the prophet were to be found, who if necessary would help them and supply them with provisions and camels. But the Bedouins had calculated that they were still about five days’ journey from Assuan.

The way led through still more desolate country, and at every halt the provisions for man and beast sank lower.

Fortunately, they could drive the camels on, and make them gallop as fast as they pleased, for the heat had not exhausted the animals’ strength. In the daytime, during the noon hours, the sun beat down fiercely upon them, but the air was always fresh and the nights so cool that Stasch, with Idris’ permission, mounted Nell’s camel to look after her health and to protect her from the cold. But his fears were groundless, for Dinah, whose eyes had greatly improved, looked carefully after her little lady.

The boy was surprised that the little one’s health had not suffered, and that she stood the journey as well as he, especially when the halts were becoming less and less frequent. Sorrow and fear, and the tears which she had shed longing for papa, had apparently not done her much harm. She had perhaps become a little thin, and her pale face was tanned by the wind, but as time went on she stood the journey better than in the beginning. Idris had given her the best camel, and had arranged the saddle very comfortably so that she could sleep, but it was the fresh desert air especially, breathed night and day, that gave her the strength to bear the fatigue and discomfort of the journey.
