These doubts persisted, and so did the tantalizing little puzzles. They weaned Billy Louise's thoughts from her own ranch worries and nagged at her with the persistence of a swarm of buffalo gnats. "Well, if he doesn't use poison, for goodness' sake, what does he use?" she asked indignantly aloud, after a period of deep thought. "I don't see why he wants to be so terribly secretive. He might be human enough to tell a person what he means. I'm sure I'd tell him, all right. I don't believe it's wolves at all. I don't see how--and still--I don't believe Ward would really lie to me." She was in this particularly dissatisfied mood when she rode out of the canyon at its upper end, where the hills folded softly down into grassy valleys where her cattle loved best to graze. Since the grass had started in the spring, she had kept her little herd up here among the lower hills; and by riding along the higher ridges every day or so and turning back a wandering animal now and then, she had held them in a comparatively small area, where they would be easily gathered in the fall. A few head of Seabeck's stock had wandered in amongst hers, and some of Marthy's. And there was a big, roan steer that bore the brand of Johnson, over on Snake River. Billy Louise knew them all, as a housewife knows her flock of chickens, and if she missed seeing certain leaders in the scattered groups, she rode until she found them. Two old cows and one big, red steer that seemed always to have a following wore bells that tinkled pleasant little sounds in the alder thickets along the creek, as she passed by. She rode up the long ridge which gave her a wide view of the surrounding hills and stopped Blue, while she stared moodily at the familiar, shadow-splotched expanse of high-piled ridges, with deep green valleys and deeper-hued canyons between. She loved them, every one; but to-day they failed to steep her senses in that deep content with life which only the great outdoors can give to one who has learned how satisfying is the draught and how soothing. Far over to the eastward a black dot moved up a green slope and slid out of sight beyond. That might be Ward, taking a short-cut across the hill to his claim beyond the pine-dotted ridge that looked purple in the distance. Billy Louise sighed with a vague disquiet and turned to look away to the north, where the jumble of high hills grew more rugged, with the valleys narrower and deeper. Here came two other dots, larger and more clearly defined as horsemen. From mere objects that stood higher than any animal and moved with a purposeful directness, they presently became men who rode with the easy swing of habit which has become a second nature. They must have seen her sitting still upon her horse in the midst of that high, sunny plateau, for they turned and rode up the slope toward her.
