A ripple in mid-stream caught his attention. While in the starlight he gazed upon it, it seemed to come nearer. Then another ripple, and another, that spread themselves out wider and wider, and in the middle of the disturbed area there appeared a tiny speck, as though a swimmer were breasting the stream. But even as he watched it, it disappeared and was lost in the darkness.
Five minutes--ten minutes passed, but the speck, whatever it was, did not reappear. What could it be? It would be foolish to alarm the camp prematurely, so he would just creep down to the water's edge and make sure. He threw off his blanket and crawled along through the reeds and willows. He had nearly reached the water when a rustling amongst the reeds caused his heart to cease beating for an instant. What could it be?
Two glaring eyeballs, that glowed like fire, were fixed upon his, not six feet away. Jack instinctively felt for his pistol, when, horror of horrors, he had left it beside the embers of the fire. He drew his hunting-knife from its sheath, keeping his eyes fixed the while upon those glaring eye-balls; when the wild creature, evidently a wolf, attracted to the river by thirst, suddenly uttered a snarl, turned tail and made off.
"Thank God!" he gasped. "Better a wolf than an Indian." For though naturally a brave lad this sudden apparition had given him a shock that made the perspiration stand out like beads on his forehead, but he quickly recovered himself and crept down to the edge of the stream.
He could just make out the dark, indistinct outline of the forest on the opposite bank, but no ripples or dark objects were visible. Then he looked down-stream, but nothing could he see.
"I must have been deceived. What a good thing I didn't alarm the camp! How they would have laughed at me," he muttered.
Just then, however, he cast his eyes upstream. As he did so, he started again. A long, dark shadow, like a log or a canoe, half-way across, seemed to be drifting towards the northern shore on which they were camped. It was not more than two hundred yards away. It seemed to crawl along, then close behind it he saw a similar object, and still another.
What were the scouts doing? Had they been betrayed? What could they be, but canoes--Indians? Then the enemy must be crossing over, and he raised his voice for one mighty shout of--
"Iroquois."
But even as he uttered that startling cry the fierce howl of the coyote, repeated twice, the signal to alarm the camp, came from the woods, and the crack of a rifle awoke a hundred echoes and roused the men to a sense of their danger.
