"I suppose Hank will tell me I did wrong," he mused, "but my conscience does not; it would be a woeful memory to carry with me that on my first night in Wyoming I took the life of a human being. Perhaps it will be as well that Hank should not know it; I will think it over."

Now, while Jack Dudley had conducted himself in some respects like a veteran, yet he had shown a dangerous short-sightedness in another direction. It will be noted that he had busied himself wholly with the single intruder, and at the moment of losing sight of him the young man was a comparatively long distance from the camp-fire. Had it been that there were two or more hostiles stealing into camp, they could not have asked a better opportunity, for it was left wholly unguarded. A single warrior would have had no trouble in creeping undiscovered to a point from which he could have sent a bullet through the unconscious forms of Hank Hazletine and Fred Greenwood. This probability never occurred to Jack until he started on his return to the fire, from whose immediate vicinity he should never have allowed himself to have been tempted.

Even then his strange remissness would not have impressed itself upon him but for a startling discovery. The fire was beginning to smoulder once more, but enough of its glare penetrated the wood for him to note the black, column-like trunks of the trees between it and him. With his gaze upon the central point, he saw a figure moving in the path of light and coming toward him. It looked as if stamped in ink against the yellow background, and, like the former intruder, was advancing without noise.

An awful fear thrilled Jack Dudley as he abruptly halted and partly raised his Winchester.

"While I have been busy with one Indian, another has entered the camp and slain Fred and Hank! He is now after me! There will be no hesitation this time in my shooting!"

Before he could secure anything like an aim, the other stepped behind one of the trunks on his right. Jack waited for him to reappear, ready to fire, but unwilling to do so until the truth was established.

While waiting thus, a low, faint, tremulous whistle reached his ears. It was the most welcome of all sounds, and raised him from the depths of woe to blissful happiness, for it was the familiar signal of Fred Greenwood that had been employed many times in their hunting excursions nearer home.

Instead of an enemy, it was his chum and dearest friend who was approaching him. Jack instantly answered the guarded hail, and the next minute the two came together.

"How is it you are awake?" was the first question of Jack.

"Because it is time for me to awake; it was agreed that I should go on duty at a little after twelve, and it must be near one o'clock."
