"Yes," the young woman answered, as she frowned, and her voice became stern, "I have a duty to accomplish. I have taken an oath, and my sister well knows that is sacred. I must go."

"But where are you going, my poor child? Whence arises this sudden thought of leaving me? What do you intend? Where are you about to proceed?"

"My sister must not ask me. Her questions would only grieve me, for I cannot answer her."

"Then you have secrets from me, Sunbeam. You will not give me your confidence? Fool! Do you fancy I do not know what you intend doing?"

"My sister knows my plan!" The Indian interrupted her with flashing eye, while a convulsive tremor passed over her limbs.

"Yes, I do," the other answered with a smile. "Unicorn is a renowned warrior, and my sister is doubtless anxious to rejoin him?"

The Indian shook her head in denial.

"No," she said, "Sunbeam is following her vengeance."

"Oh, yes, poor child," Doña Clara said, as she pressed the young squaw to her heart, "I know from what a fearful catastrophe Don Valentine saved you."

"Koutonepi is a great warrior. Sunbeam loves him; but Stanapat is a dog, son of an Apache devil."
