Kneeling behind their rocky barrier the two men silently peered into the darkness down the hill. The great ledge of rock under which they were hiding concealed from their view the burning fires of the Indians down in the roadway to the east. But the reflection of the fire could be plainly seen on the rocks and trees on the north side of the Pass. Here and there stray beams of light shot through the firs and cedars and stunted oaks that lay below them among the bowlders; and somewhere down among these little trees, watchful Jim declared that he had seen something white moving cautiously and stealthily to and fro. Pike closely questioned him, whispering his inquiries so as not to catch the ears of Kate or the children, but Jim stoutly declared that he could not be mistaken. He had marked it twice, moving from place to place, before he had quit his post and called to the corporal to come and verify for himself what he was sure he had seen. For a few moments Pike thought that it might be the Apache sentinel who had, possibly, left his position on the little hill across the road, and was seeking on his own account some clue to the whereabouts of the fugitives from the camp. Pike had seen one or two Indians running up the road to where the sentinel was stationed in order to give him some of the plunder which they had taken from the wagon, and it was now so dark that he could no longer see objects out on the plain, and, as he could hear approaching horsemen just as well on this side of the road as on that, it was quite possible that this Indian was the cause of Jim's warning.
Several minutes passed without either of them seeing anything. Then suddenly Jim's hand was placed on the corporal's arm, and in a low, tremulous voice he whispered: "Look! Look!"
Following with his eyes the direction indicated by Jim's hand, Pike could just see, probably two hundred or two hundred and fifty yards away down the hillside, something dirty white in color, very slowly and very stealthily creeping from one bowlder to another. The tops and crests of the trees and bowlders, as has been said, were tinged by the light of the fires still burning down in the roadway. The Indian yells were gradually ceasing as, one after another, seemingly overcome by the liquor that they had been drinking, they subsided into silence. A number of them, however, still kept up their monotonous dance, varied every now and then by a yell of triumph; but the uproar and racket was not to be compared with what had been going on during the torture to which Manuelito had been subjected before they had mercifully, though most horribly, put an end to his sufferings.
Nothing but the embers of the wagon and the unconsumed iron work, of course, now remained in the road. Pike judged too that the ambulance had been burned, and that nothing remained of that. But all thought as to what was going on among the Indians in the Pass was now of little account as compared with the immediate presence of this object below him. Could it be one of the Apaches? Could it be the sentinel from the other side? Its stealthy movements and the noiseless way in which it seemed to flit from rock to rock gave color to his supposition, and yet it appeared unnatural to Pike that any one of the Indians should separate himself from his comrades and go on a still hunt in the dead of the night for traces of their hated foes.
"I cannot see it now," whispered Jim. "Where is he gone?"
"Behind that big rock that you see touched by the firelight down yonder. Our trail is just about half way. Look! There it is again! Nearer, too, by fifty yards. I wish he'd get on top of one of those bowlders where the light would strike him. Then we might make him out. By Jove! He's coming up the hill. Whatever you do, don't fire. I'll tend to him."
With straining eyes they watched the strange, stealthy approach of the mysterious object. Every now and then it would totally disappear from sight and then, a moment or two afterwards, could again be dimly seen, crouching along beside some big rock or emerging behind the thick branches of some stunted tree. Nearer it came until Pike was sure it must have reached the "trail" they had made in their journeys up and down the hill.
"I never saw an Apache that could move about in the dark as quickly as that fellow. Jim, by Jimminy, I'll bet it's no Indian at all!"
"What is it, then?" muttered Jim, whose teeth would chatter a little. He had all a darkey's dread of "spooks" and was more afraid of a possible ghost than an actual Tonto.
"That's a lynx or a wild-cat, man! They have a dingy white coat to their backs, in places at least, and you've only stirred up some mighty small game. See here, Jim, you're getting nervous. I'll have to call Ned out here with his little Ballard to take your place if you are going to—There! What did I tell you?"
