Margaret rode on the familiar trail, and for the first hour just let herself be glad that school was over and she could rest and have no responsibility. The sun shimmered down brilliantly on the white, hot sand and gray-green of the greasewood and sage-brush. Tall spikes of cactus like lonely spires shot up now and again to vary the scene. It was all familiar ground to Margaret around here, for she had taken many rides with Gardley and Bud, and for the first part of the way every turn and bit of view was fraught with pleasant memories that brought a smile to her eyes as she recalled some quotation of Gardley's or some prank of Bud's. Here was where they first sighted the little cottontail the day she took her initial ride on her own pony. Off there was the mountain where they saw the sun drawing silver water above a frowning storm. Yonder was the group of cedars where they had stopped to eat their lunch once, and this water-hole they were approaching was the one where Gardley had given her a drink from his hat. She was almost glad that Bud was not along, for she was too tired to talk and liked to be alone with her thoughts for this few minutes. Poor Bud! He would be disappointed when he got back to find her gone, but then he had expected she was going in a few days, anyway, and she had promised to take long rides with him when she returned. She had left a little note for him, asking him to read a certain book in her bookcase while she was gone, and be ready to discuss it with her when she got back, and Bud would be fascinated with it, she knew. Bud had been dear and faithful, and she would miss him, but just for this little while she was glad to have the great out-of-doors to herself. She was practically alone. The two sphinx-like figures riding ahead of her made no sign, but stolidly rode on hour after hour, nor turned their heads even to see if she were coming. She knew that Indians were this way; still, as the time went by she began to feel an uneasy sense of being alone in the universe with a couple of bronze statues. Even the papoose had erased itself in sleep, and when it awoke partook so fully of its racial peculiarities as to hold its little peace and make no fuss. Margaret began to feel the baby was hardly human, more like a little brown doll set up in a missionary meeting to teach white children what a papoose was like.
