It is singular how, in the most critical moments, certain thoughts will obtrude themselves. While Wharton Edwards was peering over the ravine and wondering whither Blazing Arrow had vanished, a sudden suspicion caused him to raise his rifle and examine its lock.

There was not a grain of powder in the pan and no charge in the barrel. All the time that it had been in the hands of the Shawanoe and himself it was as useless as a stick. It seemed incredible that such should have been the fact, and yet here was the evidence before his own eyes.

What was equally apparent and more astonishing was that Blazing Arrow must have been unsuspicious of the truth. The youth had not reloaded the weapon after firing the last time, and it was, therefore, empty when he flung it across the ravine preparatory to making his leap. It had been picked up by the runner, who failed, in the excitement, to notice the oversight, taking it for granted that it was ready for use. In the rush of the pursuit he had no chance of examining it, and when he recovered his senses the gun was in the hands of its owner.

But had the Shawanoe known the truth, when the lad stood within a few paces defying him, his pretended weakness would have gone in a flash, and, bounding to his feet, he would have leaped upon his conqueror like a panther.

"That's the strangest thing I ever knew," exclaimed Wharton, with a shudder at his inexplicable escape; "I can't understand how he and I missed seeing it."

When it is remembered that the fact of an old-fashioned flintlock being unloaded is perceptible at a glance, the feature of the mistake is the more remarkable.

The discovery threw the youth into something of a panic. He felt as if the venomous old man was about to assail him from among the trees, and, with a quick glance around, made desperate haste to reload the gun. Not until the ball was rammed down the barrel and the powder was in the pan did he breathe freely.

"There!" he exclaimed, drawing a sigh of relief, "when I make that blunder again I deserve to be shot, but the laugh is on Blazing Arrow more than on me."

Now that he had a trusty weapon in his possession, and the Shawanoe had none, the situation of the latter was like that of a wild beast and a marksman. Could the beast leap unawares upon the marksman he could overcome him, but the latter had only to maintain his watchfulness.

Had Blazing Arrow rushed toward the lad after he had found his gun was empty, and before he reloaded it, Wharton's only resource would have been to take again to his heels; for, active and athletic as he was, he could not possibly be a match for the powerful, full-grown warrior, and it would have been foolhardy on his part to take any such risk.

The disappearance of the Shawanoe during the brief absence of Wharton was proof that the wily wretch was shamming. His fall had given him a severe shock, but no bones were broken; and had the youth heeded the request to help him to rise he would have snatched him off his feet in a twinkling and had him at his mercy.

Whither had he gone? The dread that he might be stealing among the trees in the effort to surprise him caused young Edwards to make a hasty withdrawal from the wood to the open plain which had been the scene of the severest race of his life.

When he stood clear of the trees, and beyond reach of any sudden surprise, he breathed freely for the first time.

"Now let him come, if he wants to. I can outrun him anyway, but I don't run any more races," added Wharton, glancing down at his gun.

The Shawanoe, who was doubtless glaring at him from some point of concealment, must have relied upon cunning to outwit his victim.

"I wonder what sort of yarn he will tell his people when he goes back?" mused Wharton. "How will he account for his failure to capture me, and what explanation will he give for the loss of my gun? I suppose he will say he concluded to shoot me, and broke it over my head and flung it away. But if I come out of this trouble they will learn the truth some day."

Not forgetting to be on his guard against his foe, the lad walked slowly across the clearing, taking the back trail. He was considering the best thing to do. But for Larry Murphy, he would have made all haste in the opposite direction. The block-house was almost twenty miles away, and this flurry had delayed the couple so long that there was no time to spare. Wharton's parents would become anxious and set out to meet the boys. If they should become involved with these Indians, direful consequences were likely to follow.

But Wharton could not desert his comrade. He was a mile or two away, near the main party of warriors, and Providence alone could prevent his falling into their hands. Larry would naturally suppose that his friend was not far from him, and it would be just like the fellow to run into the worst sort of peril in the hope of doing him service.

"I must get back to him as soon as I can. If he could only know how fortunate I have been it would be easy for him to steal around the whole party and join me here. Then we could do some fast travelling, and be at the block-house before sunrise to-morrow."

Since, however, such a state of affairs was out of the question, Wharton had only to face matters as they were.

One ground for hope cheered him. The sultry summer afternoon was drawing to a close, and night was at hand. He could manoeuvre in the darkness much better than when the sun was shining. He and the Irish lad had a system of calls and signals by which they communicated when within hearing distance of each other. He could fall back on this when darkness fell.

With his controlling wish there was but one thing for him to do; that was to make his way with the utmost care to the region of the falls, where he had parted from Larry. If his comrade had been wise enough to keep out of the hands of the Shawanoes he was hopeful of opening communication with him. A few more hours must decide the question.

He increased his pace. When he reached the wood on the opposite side of the plain it was twilight. He walked rapidly, as though in a hurry, but after going far enough to be beyond sight he came stealthily back and looked toward the point where he had reloaded his gun. As he did so he caught the outlines of a figure in the dim light steadily approaching, and he knew it was Blazing Arrow, the Shawanoe.
