"Thus it is; a day's march in advance. But Mohammed Ali, so everybody says, is a daring and untiring soldier. Who knows but he may march at night, too, and unite with Youssouf?"

"You are right, Arnhyn," replied Bardissi, "and it is this that I wish to prevent. I wish, if possible, to avoid encountering Mohammed Ali. It is of this that I desire to speak with you. Come, let us withdraw a little farther from the tents and discuss this matter."

All is silent. The Mamelukes and kachefs lie sleeping beside their horses. No one hears what passes between the Mameluke bey, Osman Bardissi, and the Bedouin sheik, Arnhyn.

They speak in whispers; no one sees Arnhyn display his white teeth in his delight, nor sees the glad smile that suddenly lights up his countenance.

"A splendid scheme, master. By Allah! I would do it though you had not promised so rich a reward. I give you my word it shall be done as you direct. We will make Sarechsme Mohammed Ali harmless."

"You will start out at once?" said Bardissi.

"Immediately, master, for I must soon return," replied Arnhyn. "By sunrise you will come up with Youssouf, and I must be there with my ravens to gather the spoils. I will now fly to my tent; there near the Pyramids I shall meet my daughter Butheita, and she will arrange the rest.

You will find me at your tent by morning. If I am not there, Osman Bey Bardissi, you will know that the Bedouin sheik, Arnhyn, is no longer among the living, and that the sarechsme, Mohammed Ali, has been too shrewd for him."
