"I shall be watching and I shall know whether you have the lady or not," went on the girl, sharply. "If you do not bring the lady with you there will be no money and no provisions waiting for you. But if you bring the lady you can untie the horse and take him with you. You will need the horse to carry the things. When you get to Walpi you can set him free. He is branded and he will likely come back. We shall find him. See, I will put the gold pieces in this tin can."

She picked up a sardine-tin that lay at her feet, slipped the gold pieces in an envelope from her pocket, stuffed it in the tin, bent down the cover, and held it up.

"This can will be packed on the top of the other provisions, and you can open it and take the money out when you untie the horse. Then hurry on as fast as you can and get as far along the trail as possible to-night before you camp. Do you understand?"

The Indian nodded once more, and Rosa felt that she had a confederate worthy of her need.

She stayed a few minutes more, going carefully over her directions, telling the Indian to be sure his squaw was kind to the lady, and that on no account he should let the lady get uneasy or have cause to complain of her treatment, or trouble would surely come to him. At last she felt sure she had made him understand, and she hurried away to slip into her pretty white dress and rose-colored ribbons and ride to school. Before she left her room she glanced out of the window at the Indians, and saw them sitting motionless, like a group of bronze. Once the Indian stirred and, putting his hand in his bosom, drew forth the white letter she had given him, gazed at it a moment, and hid it in his breast again. She nodded her satisfaction as she turned from the window. The next thing was to get to school and play her own part in the Commencement exercises.

The morning was bright, and the school-house was already filled to overflowing when Rosa arrived. Her coming, as always, made a little stir among admiring groups, for even those who feared her admired her from afar. She fluttered into the school-house and up the aisle with the air of a princess who knew she had been waited for and was condescending to come at all.

Rosa was in everything—the drills, the march, the choruses, and the crowning oration. She went through it all with the perfection of a bright mind and an adaptable nature. One would never have dreamed, to look at her pretty dimpling face and her sparkling eyes, what diabolical things were moving in her mind, nor how those eyes, lynx-soft with lurking sweetness and treachery, were watching all the time furtively for the appearance of the old Indian.

At last she saw him, standing in a group just outside the window near the platform, his tall form and stern countenance marking him among the crowd of familiar faces. She was receiving her diploma from the hand of Margaret when she caught his eye, and her hand trembled just a quiver as she took the dainty roll tied with blue and white ribbons. That he recognized her she was sure; that he knew she did not wish him to make known his connection with her she felt equally convinced he understood. His eye had that comprehending look of withdrawal. She did not look up directly at him again. Her eyes were daintily downward. Nevertheless, she missed not a turn of his head, not a glance from that stern eye, and she knew the moment when he stood at the front door of the school-house with the letter in his hand, stolid and indifferent, yet a great force to be reckoned with.

Some one looked at the letter, pointed to Margaret, called her, and she came. Rosa was not far away all the time, talking with Jed; her eyes downcast, her cheeks dimpling, missing nothing that could be heard or seen.

Margaret read the letter. Rosa watched her, knew every curve of every letter and syllable as she read, held her breath, and watched Margaret's expression. Did she suspect? No. A look of intense relief and pleasure had come into her eyes. She was glad to have found a way to go. She turned to Mrs. Tanner.
