We must go back with our story four days. Sixty leagues from Uargla an immense caravan was encamped. Not a tree or a green leaf could be seen for miles around, and yet it was here that Monte-Cristo cast his tent. Hardly had he arrived at Bona than he regained the vigor of his youthful days, and two hours after his landing Monte-Cristo was already on his way to the desert with a well-organized caravan. One hundred energetic men accompanied him, and his train consisted of two hundred horses and eight hundred camels. He and Spero were at the head of the party; Bertuccio, Jacopo and Coucou followed behind. Before he had left the ship, the count had called his son aside, and putting a map before him, he pointed with his finger to Uargla and said:

"This is the place we must go to—in Uargla we shall find what we are looking for."

Monte-Cristo knew that in the centre of the desert the queen of the oases, Uargla, lay, and that it was the principal refuge of sedition. He had known that Abd-el-Kader's imprisonment was but the commencement of a long and bloody war. The name given him by the Zouave, Mohammed ben Abdallah, he knew to be that of a treacherous villain. How did it happen, then, that Monte-Cristo had not recognized in the Arab who enjoyed his hospitality Mohammed ben Abdallah? The count had been rewarded for his generosity by having his cabin broken open, the contents of his safe scattered about, and being told to beware of the Khouans.

What the Fenians are to Ireland, the Thugs to India, the Khouans are to Arabia. They formed a brotherhood whose object was the murder and annihilation of all Europeans and Christians. Monte-Cristo knew the savage nature of these enemies. He was now within four days' journey of Uargla, and began to hope that perhaps he would find what he was seeking. When night came, Monte-Cristo withdrew with Spero to his tent. The count wrote to Haydee. A courier went north every day, but Monte-Cristo had not yet been able to send Mercedes any consolation. Spero, tired out by the fatigues of the day, had fallen asleep, and the father often gazed with pleasure at the finely chiselled face. How many dreams and hopes rested on this son! Yes, when he gazed at Spero, he had to confess that he had dealt too harshly with Morcerf. If he had been a father at that time, he would have hesitated before he had carried out his plan of vengeance. Ah! he must hurry and bring back to Mercedes her son, so that the punishment should not fall on Spero's head.

Suddenly Spero uttered a cry in his sleep, and looked wildly about him.

"No, no; let me go! Papa, help—they are carrying me away—help me!"

Monte-Cristo, frightened, bent over the sleeping boy.

"What is the matter, Spero?" he asked, tenderly; "have you been dreaming?"

"Oh, how glad I am it was only a dream! I will tell it to you."
