Having, at length, brought them to points and places, which afforded them the command of the avenues to the rock, the next object of their guide was to ascertain where the outlaw was at that moment secreted.  It was highly important to know where to enter—­where to look—­and not waste time in fruitless search of places in which a single man might have a dozen blind seekers at his mercy.  The cunning of the idiot conceived this necessity himself.

His policy made each of the party hide himself out of sight, though in a position whence each might see.

All arranged as he desired, the urchin armed himself with a rock, not quite as large as his own head, but making a most respectable approach to it.  This, with the aid of coat and kerchief he secured upon his back, between his shoulders; and thus laden, he yet, with the agility of the opossum, her young ones in her pouch, climbed up a tree which stood a little above that inner chamber which Guy Rivers had appropriated for himself, and where, on more occasions than one, our idiot had peeped in upon him.  Perched in his tree securely, and shrouded from sight among its boughs, the urchin disengaged the rock from his shoulders, took it in both his hands, and carefully selecting its route, he pitched it, with all his might, out from the tree, and in such a direction, that, after it had fairly struck the earth, it continued a rolling course down the declivity of the rocks, making a heavy clatter all the way it went.

The ruse answered its purpose.  The keen senses of the outlaw caught the sound.  His vigilance, now doubly keen, awakened to its watch.  We have seen, in previous pages, the effect that the rolling stone had upon the musing and vexed spirit of Guy Rivers, after the departure of Dillon.  He came forth, as we have seen, to look about for the cause of alarm; and, as if satisfied that the disturbance was purely accidental, had retired once more to the recesses of his den.

Here, throwing himself upon his couch, he seemed disposed to sleep.  Sleep, indeed!  He himself denied that he ever slept.  His followers were all agreed that when he did sleep, it was only with half his faculties shut up.  One eye, they contended, was always open!

Chub Williams, and one of the hunters had seen the figure of the outlaw as he emerged from the cavern.  The former instantly identified him.  The other was too remote to distinguish anything but a slight human outline, which he could only determine to be such, as he beheld its movements.  He was too far to assault, the light was too imperfect to suffer him to shoot with any reasonable certainty of success, and the half of the reward sought by his pursuers, depended upon the outlaw being taken alive!

But, there was no disappointment among the hunters.  Allowing the outlaw sufficient time to return to his retreats, Chub Williams slipped down his tree—­the rest of the party slowly emerged from their several places of watch, and drew together for consultation.
