This was as effective as if he had called out in a loud voice that the Iroquois were upon them. Jo paused on the instant, and like the rest glanced at the Indian to learn what it meant. Up to that moment all, with the exception of him who managed the pole, were seated on the gunwale, but the Mohawk, at the instant of uttering the exclamation, rose to his feet, and was seen to be looking toward the land which was their destination. Since this placed his back toward his friends, they could only gaze in the same direction in quest of the cause of his alarm.
At first they saw nothing, but in a few seconds the explanation came in the shape of a light, which resembled a torch carried in the hands of some one who was walking along the edge of the water. As this light showed itself near the spot at which they were aiming, it was high time they halted. The whole party, gazing in the direction of the strange illumination, made an interesting tableau while drifting down the river. The torch—if such it was—continued visible but a few seconds, when it vanished as if plunged into the water.
Here was another unexpected interference with their plans, and the old feeling of doubt came to the heart of Rosa Minturn, when she recalled the extraordinary delay that had attended their attempts to get to Fort Wilkesbarre, and now when her hopes were high, and they were actually in sight of the shore, this mysterious light had come to warn them off.
Lena-Wingo did not stand idle long when they were confronted by such danger, but turning about, stepped hastily back to where Jo was awaiting the word of command, and took the pole from him.
"Must go back—Iroquois heard us coming—watch for us."
More than one heart sank as these words were uttered, for all felt that it was a bad omen thus to turn back, when they were so near the land they were seeking. There was another fact which was equally apparent, and which caused them no very pleasant reflection. They had very likely betrayed themselves by their own indiscretion, in talking in tones that reached the ears of those who were watching for them. No one was to blame, therefore, but themselves for the unfortunate situation in which they were placed.
Jo yielded the pole without a murmur, and the Mohawk applied it with a power and skill that made the retrogression much faster than was the progress in the other direction. When the deepest portion of the channel was reached, Lena-Wingo used the implement with a great deal more cleverness than Ned Clinton had displayed, and it was crossed in considerably less time than before. Then, as the more shallow water came, and the craft was quite manageable, the Mohawk stopped work, and holding the pole motionless and motioning his friends not to speak or move, he listened, they also using their eyes and ears to the best of their ability.
