He had covered half of the distance to the creek when Coaley again called his attention to something behind him. This time Lance glimpsed what looked very much like the crown of a hat moving in a dry wash that he had crossed not more than five minutes before. He pulled up, studied the contour of the ground behind him, looked ahead, saw the mark of a shod hoof between two rocks. The hoof mark pointed toward the crossing. Lance, however, turned down another small depression where the soil lay bare and Coaley left clean imprints, trotted along it until a welter of rocks made bad footing for the horse, climbed out and went on level. Farther up the valley an abrupt curve in Squaw Creek barred his way with scraggly, thin willow growth that had winding cow trails running through it. Into one of these Lance turned, rode deep into the sparse growth, stopped where the trail swung round a huge, detached boulder, dismounted and dropped Coaley's reins to the ground and retraced his steps some distance from the trail, stepping on rocks here and there and keeping off damp spots. He reached the thin edge of the grove, stood behind a stocky bush and waited. In two or three minutes--they seemed ten to Lance--he saw the head and shoulders of a rider just emerging from the gully he himself had so lately followed. Back on Coaley, following the winding trail, Lance pondered the matter. The way he had come was no highway--no trail that any rider would follow on any business save one. But just why should he be followed? He had thought at first that some one was trailing the Devil's Tooth outfit, as he had been doing, but now it seemed plain that he himself was the quarry. He flicked the reins on Coaley's satiny neck, and the horse broke at once into a springy, swift trot, following the purposeless winding of the cow path. When they emerged upon the other side where the creek gurgled over a patch of rocks like cobblestones, Lance stopped and let him take a sip or two of water, then struck off toward the bluff, letting Coaley choose his own pace, taking care that he kept to low ground where he could not be seen. For an hour he rode and came to the junction of Mill Creek and the Squaw. Then, climbing through chokecherry thickets up a draw that led by winding ways to higher ground, Lance stopped and scrutinized the bottomland over which he had passed. Coaley stood alert, watching also that back trail, his ears turned forward, listening. After a moment, he began to take little mincing steps sidewise, pulling impatiently at the reins. As plainly as a horse could tell it, Coaley implored Lance to go on. But Lance waited until, crossing an open space, he saw a rider coming along at a shambling trot on the trail he had himself lately followed. He frowned thoughtfully, turned Coaley toward home and rode swiftly in a long, distance-devouring lope.
