When she turned to look full in his face, he decided that she had almost beautiful eyes.
She had arisen while he was watching her, and seemed to be looking off with sudden apprehension.

He followed her gaze, and saw several dark figures moving against the sky.
"It's a herd of antelope," she said with relief; "but it's time we hit the trail." She turned, and put her things together with incredible swiftness, giving him very little opportunity to help, and mounted her pony without more words.
For an hour he followed her at high speed as she rode full tilt over rough and smooth, casting furtive, anxious glances behind her now and then, which only half included him.

She seemed to know that he was there and was following; that was all.
The young man felt rather amused and flattered.

He reflected that most women he knew would have ridden by his side, and tried to make him talk.
But this girl of the wilderness rode straight ahead as if her life depended upon it.

She seemed to have nothing to say to him, and to be anxious neither to impart her own history nor to know his.
Well, that suited his mood.
