It is impossible to exaggerate the difficulty of the work thus laid out for himself. It brought him in direct conflict with the subtlety of the worst of all American tribes, and upon what may be called their own ground. His chances of success were hardly one in a hundred.

But, despite the discouraging outlook, the parent was buoyed up by a fact, and by a theory which he had persuaded himself to believe was also a fact. During his two years in Southern Arizona he had become familiar with much of the Apache Range, and especially with that portion he now meant to visit. He was quite confident that he knew where the little company would make their first halt of any duration; and instead, therefore, of attempting to follow their trail, he proposed to make directly for the rendezvous.

There was more than one advantage in adopting this course, chief of which was that it involved far less risk to himself. The fugitives would watch their own trail and be prepared to ambuscade any of their pursuers who tried to follow it, while, by taking another route to the rendezvous, he was sure to escape that peril. This, however, as will be seen, hinged on the question whether or not he had made a mistake in locating Maroz, Ceballos, and such of their companions as they might have gathered round them. That remained to be proved by actual test.

The theory that did much to buoy up Freeman was the rather fanciful one that the Apaches were holding his child as a hostage for certain unlawful deeds not yet committed. They had been offered immunity for the crimes of the morning, and had scoffed at the offer. With the opportunity of striking their enemies hard, they could not surrender before doing so. They must give full vent to their viciousness as preliminary to settling down to become good Indians. When the time came, and they were ready to yield, they would have the advantage of giving the authorities the alternative of accepting their submission, with the restoration of the child unharmed, or of consenting to its death by refusing their terms.

This was the theory, and as I have said, it was a fanciful one, which Freeman did not mention to the lieutenant, through fear that he would shake his head and declare it could have no possible existence in fact. He had managed to make himself believe it, and it nerved his arm to the attempt that otherwise would have been the height of folly.

The solitary pursuer had not penetrated far among the foothills, when, as he anticipated, a point was reached where his pony could be of no further use to him. Accordingly he dismounted, removed the saddle and bridle and turned him loose, to wander at will, until he should come back to claim him.

From the point where he left his animal to where he believed the Apaches were gathered was hardly a mile, but the distance was traversed with such extreme care, that the long, hot afternoon was drawing to a close before he was near his destination. Well aware that the slightest mistake on his part would be fatal, he determined to make none, if patience, caution and circumspection could prevent it.

That stealthy advance among the stunted vegetation, over and around vast rocks, down declivities, gullies and gorges, through hollows and ravines and up abrupt slopes, was enough to try the endurance and nerve of the bravest man. His vision was so circumscribed that he often failed to see a dozen feet in advance, and he never caught sight of a boulder or rock, that he did not ask himself whether one or more of his enemies was not kneeling behind it, with leveled Winchester, awaiting just such an opportunity to bring him down.

He could no longer detect anything of the signal fire that was the means of bringing him thither, and he believed it had been extinguished; but when he was congratulating himself on his success, he was startled to find that, without any thought on his part, he had struck the trail of Maroz and Ceballos. There were the hoofprints of their unshod ponies, distinctly marked, where they had borne their riders up the steep slope, and probably for a goodly distance beyond, before they were discarded.

The path showed so plainly that it would have been easy to follow it; but, instead of doing so, he hastily crossed it and made his own course to the supposed rendezvous more circuitous than before.
