A few steps farther, and Blue stopped short in the trail to look and listen. Billy Louise could see the nervous twitchings of his muscles under the skin of neck and shoulders, and she smiled to herself. Nothing could ever come upon her unaware when she rode alone, so long as she rode Blue. A hunting dog was not more keenly alive to his surroundings.
"Go on, Blue," she commanded after a minute. "If it's a bear or anything like that, you can make a run for it; if it's a wolf, I'll shoot it. You needn't stand here all night, anyway."
Blue went on, out from behind the willow growth that hid the open. He returned to his calm, picking a smooth trail through the scattered rocks and tiny washouts. It was the girl's turn to stare and speculate. She did not know this horseman who sat negligently in the saddle and looked up at the cedar-grown bluff beyond, while his horse stood knee-deep in the little stream. She did not know him; and there were not so many travelers in the land that strangers were a matter of indifference.
Blue welcomed the horse with a democratic nicker and went forward briskly. And the rider turned his head, eyed the girl sharply as she came up, and nodded a cursory greeting. His horse lifted its head to look, decided that it wanted another swallow or two, and lowered its muzzle again to the water.
Billy Louise could not form any opinion of the man's age or personality, for he was encased in a wolfskin coat which covered him completely from hatbrim to ankles. She got an impression of a thin, dark face, and a sharp glance from eyes that seemed dark also. There was a thin, high nose, and beyond that Billy Louise did not look. If she had, the mouth must certainly have reassured her somewhat.
Blue stepped nonchalantly down into the stream beside the strange horse and went across without stopping to drink. The strange horse moved on also, as if that were the natural thing to do--which it was, since chance sent them traveling the same trail. Billy Louise set her teeth together with the queer little vicious click that had always been her habit when she felt thwarted and constrained to yield to circumstances, and straightened herself in the saddle.
"Looks like a storm," the fur-coated one observed, with a perfectly transparent attempt to lighten the awkwardness.
Billy Louise tilted her chin upward and gazed at the gray sweep of clouds moving sullenly toward the mountains at her back. She glanced at the man and caught him looking intently at her face.
