Their road had, after its first sharp ascent from the river, followed the verge of those stupendous cliffs which rise sheer and bare on the eastern side of the mighty torrent that has channelled them. The young men had paused many times to gaze on the leaping surges and awful billows that raged in fury two hundred feet beneath them, or to listen, awe-struck, to the ceaseless thunder of falling waters, with which earth and air quivered. Now, within three miles of the cataract, they paused again on the brink of a lateral rent in the sheer wall of rock, so deep and black as to have won for itself the name of Devil's Hole. The road winding around the brink of this abyss was skirted on its further side by a steep and densely wooded slope. It was indeed a deadly place for an ambuscade, as several bodies of British troops subsequently discovered to their sorrow, and the young soldiers shuddered as they reflected upon its possibilities.

Suddenly, as they stood motionless and silent, Christie was amazed to have his companion spring from his side as though he had been shot, dart across the road, and disappear in the bushes beyond. There was a momentary sound of crackling sticks and swishing branches, and then all was still. Unable to account for this mysterious proceeding, and not knowing what action to take, Ensign Christie stood motionless, where he was left, for some minutes. Then Donald reappeared, walking down the road as calmly as though nothing extraordinary had happened, though breathing heavily from his recent exertions.

"The rascal was too quick for me," he said, as he rejoined his companion.

"What rascal? What do you mean?" asked the bewildered ensign.

"I don't know; wish I did. All I know is that it was an Indian, and that he was watching us. I noticed his tracks some distance back, and also noticed that just before we reached this point they turned abruptly into the underbrush. As we stood looking down that hole, I heard a twig snap, and knew he was close at hand. I thought I might surprise him, but, as I said, he was too quick for me, and I only caught a flying glimpse of him as he disappeared."

"Well, it seems curious," meditated Christie, "but I neither noticed any footprints nor heard a sound, save the thunder of yonder waters."

"It doesn't strike me so," replied Donald; "for if I had not been born and brought up in the woods, I should not be apt to notice such things either. As it is, I should feel very much ashamed not to have noticed them. Now, I think we had best wait here for the rest of the party. It is possible there may be mischief afoot. I wouldn't say anything to needlessly alarm the paymaster, though."

"All right," agreed Christie; "but what could be the chap's object in spying our movements?"

"It is hard to say; but I am satisfied that there is a general Indian war much nearer at hand than Major Wilkins is willing to admit, and in that case we must be prepared at any moment for all sorts of unexpected happenings. I only wish I was by my sister's side in one of Cuyler's boats, and could give the lieutenant warning of what to expect."

"So do I," assented Christie so heartily that the other looked at him quizzically, and he hastened to add, "I mean so do I wish you were there, though I trust you may be mistaken in your prophecy. In case there is any trouble, though, I hope I may reach my post before it breaks out."
