Then he rode boldly forth on the trail.  He calculated that old Creech would take Lucy to some wild retreat in the canyons and there wait for Joel and the horses.  Creech had almost certainly gone on and would be unaware of a pursuer so closely on his trail.  Slone took the direction of the trail, and he saw a low, dark notch in the rocky wall in the distance.  After that he paid no more attention to choosing good ground for Wildfire than he did to the trail.  The stallion was more tractable than Slone had ever found him.  He loved the open.  He smelled the sage and the wild.  He settled down into his long, easy, swinging lope which seemed to eat up the miles.  Slone was obsessed with thoughts centering round Lucy, and time and distance were scarcely significant.

The sun had dipped full red in a golden west when Slone reached the wall of rocks and the cleft where Creech’s tracks and Lucy’s, too, marked the camp.  Slone did not even dismount.  Riding on into the cleft, he wound at length into a canyon and out of that into a larger one, where he found that Lucy had remembered to leave a trail, and down this to a break in a high wall, and through it to another winding, canyon.  The sun set, but Slone kept on as long as he could see the trail, and after that, until an intersecting canyon made it wise for him to halt.

There were rich grass and sweet water for his horse.  He himself was not hungry, but he ate; he was not sleepy, but he slept.  And daylight found him urging Wildfire in pursuit.  On the rocky places Slone found the cedar berries Lucy had dropped.  He welcomed sight of them, but he did not need them.  This man Creech could never hide a trail from him, Slone thought grimly, and it suited him to follow that trail at a rapid trot.  If he lost the tracks for a distance he went right on, and he knew where to look for them ahead.  There was a vast difference between the cunning of Creech and the cunning of a wild horse.  And there was an equal difference between the going and staying powers of Creech’s mustangs and Wildfire.  Yes, Slone divined that Lucy’s salvation would be Wildfire, her horse.  The trail grew rougher, steeper, harder, but the stallion kept his eagerness and his pace.  On many an open length of canyon or height of wild upland Slone gazed ahead hoping to see Creech’s mustangs.  He hoped for that even when he knew he was still too far behind.  And then, suddenly, in the open, sandy flat of an intersecting canyon he came abruptly on a fresh trail of three horses, one of them shod.

The surprise stunned him.  For a moment he gazed stupidly at these strange tracks.  Who had made them?  Had Creech met allies?  Was that likely when the man had no friends?  Pondering the thing, Slone went slowly on, realizing that a new and disturbing feature confronted him.  Then when these new tracks met the trail that Creech had left Slone found that these strangers were as interested in Creech’s tracks as he was.  Slone found their boot-marks in the sand—­the hand-prints where some one had knelt to scrutinize Creech’s trail.
