A feverish flush covered Don Estevan's face; a convulsive tremor flew over his limbs. "Voto a brios!" he muttered, gloomily; "whatever be the condition you lay down, I accept it, if you serve me as you say."

"My brother must not pledge himself lightly," the Indian retorted, with a grin. "He does not know the condition yet; perhaps he will regret having been so hasty."

"I repeat to you," Don Estevan repeated firmly, "that I accept the condition, whatever it be. Let me know it, then, without further delay."

The cautious Indian hesitated, or appeared to hesitate, for two or three minutes, which seemed an age to the Mexican. At length he went on, in a perfidiously gentle voice. "I know where the two Palefaced maidens are whom my brother seeks in vain."

Don Estevan, at these words, bounded as if he had been stung by a serpent. "You know it!" he shouted, as he squeezed his arm violently, and looked fixedly at him.

"I know it," Addick answered, still with perfect calmness.

"It is not possible."

The Indian smiled contemptuously. "It was under my guardianship," he said, "and guided by me, that they reached their present abode."

"And you can lead me to it?"

"I can."
