"What you name?" he asked.

"Nina—Nina Carroll." Then with a shy little smile, "The boys call me 'Princess.'"

"Umph!" again grunted the Indian, and mounting his pony rode swiftly away.

As the pioneers traveled on through the heat and dust of that day the hearts of Joshua Peniman and his wife were deeply troubled. It was not alone that their worst fears of the perils of the plains had been realized in the attack of the night before, but the menace and mystery of the theft of the dispatch-box left a deep sense of fear and depression upon them.

"I cannot but fear for the child," Joshua Peniman said, after long study. "We know nothing about her, who she is, what her life may represent, or what enemies her family may have had. The thought is forcing itself upon me that we should not keep her with us, that we must leave her at the first Mission we come to, as her mother requested. They may be able to get her back to her own people."

"But who are her people? How can we ever tell that now? Every bit of information, every letter, address, paper, everything relating to her or her relatives, was in that box."

"But surely the girl herself knows——"

"Very little. I have talked with her. It appears that she and her parents have been traveling abroad a great deal of the time since she was born. She knows that they lived in New York, also for a time in St. Louis, but she does not remember the address in either place. Her mother's parents are dead, I believe, and I judge from things she has told me that there must have been some trouble with her father's family, and that the young couple lived rather an independent existence." Then after a long pause, "Somehow I cannot bear to leave the child at a Mission. Think of leaving our Ruth——"

"I know, Hannah, but her safety——"

"Yes, I realize that. We have the right, perhaps, to jeopardize the lives of our own family in this trip across the plains, but have we the right to expose the life and safety of this child, that has been left in our care?"
