"I think that they allowed them to get into too much of a gallop and now cannot check them," answered Stas.

But observing that the little girl's face was becoming pale, he shouted at the Bedouins, running ahead, to slacken their pace. His calls, however, had only this result: that again resounded the cries of "Yalla," and the animals increased their speed.

The boy thought at first that the Bedouins did not hear him, but when on his repeated orders there was no response and when Gebhr, who was riding behind him, did not cease lashing the camel on which he sat with Nell, he thought it was not the camels that were so spirited but that the men for some reason unknown to him were in a great hurry.

It occurred to him that they might have taken the wrong road and that, desiring to make up for lost time, they now were speeding from fear that the older gentlemen might scold them because of a late arrival. But after a while he understood that such could not be the case, as Mr. Rawlinson would have been more angered for unnecessarily fatiguing Nell. Then what did it mean? And why did they not obey his commands? In the heart of the boy anger and fear for Nell began to rise.

"Stop!" he shouted with his whole strength, addressing Gebhr.

"Ouskout! (be silent)!" the Sudânese yelled in reply; and they sped on.

In Egypt night falls about six o'clock, so the twilight soon became extinct and after a certain time the great moon, ruddy from the reflection of the twilight, rolled on and illuminated the desert with a gentle light.

In the silence could be heard only the heavy breathing of the camels, the rapid hoof-beats on the sand, and at times the swish of whips. Nell was so tired that Stas had to hold her on the saddle. Every little while she asked how soon they would reach then destination, and evidently was buoyed up only by the hope of an early meeting with her father. But in vain both children gazed around. One hour passed, then another; neither tents nor camp-fires could be seen.

Then the hair rose on Stas' head, for he realized that they were kidnapped.
