The Arabs mounted and were soon dashing across the desert, headed by the Sultan, who had hastily stanched the blood flowing from his arm and bound up the wound.

Half an hour later, Monte-Cristo and his men reached the oasis. The Count and Captain Joliette rode to the wells and at once saw where the grass had been beaten down by the Khouans and their horses.

"They have been here and recently, too," said Captain Joliette.

"Thank God!" said Monte-Cristo, fervently. "We are on their track! But what is that?" he added. "Is it blood?"

Coucon and Fanfar, who had been attentively examining the stain, simultaneously answered:

"It is blood."

"My God!" cried Monte-Cristo, with a convulsive start, "then they have slain my son!"

"Not so, Count," said Captain Joliette. "Had they slain Esperance they would have left his body here. But see," resumed he, pointing to the spot where Esperance had made the attack on Maldar; "here are evidences of a struggle; they have fought among themselves and one of them has been wounded."

"Heaven grant it may be so!" said Monte-Cristo.
