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. CHAPTER XII. FORCED BACKWARD. Ear and eye were strained to catch sound or sight that would tell something of their enemies. All, even the Mohawk, expected to hear the ripple of the paddles of the Iroquois in pursuit, but the stillness of the tomb was not more profound than that in which they were now enfolded. Probably a half mile below them another light was seen shining, and almost directly opposite was a similar one. It looked as if the Iroquois were signaling to one another; and, if it so happened that this scow, with its occupants, was the object of these communications, the latter might well feel anxiety about their situation. Lena-Wingo seemed puzzled to find that there was no evidence of his enemies being immediately behind them, for he was confident that the light which had arrested the forward movement of the boat was not only in the hands of one of the Iroquois, but was intended as a signal to apprise others that the fugitives had been discovered, and the time had come to close in upon them. What, therefore, meant this profound stillness, at a time when the sounds of the most active pursuit ought to have been heard? Could it mean, after all, that the light was an accident, and the redmen had seen nothing of the fugitives stealing in upon them? While the Mohawk was revolving the matter in his mind, Rosa Minturn uttered a suppressed exclamation: "See there!" It so happened, at that moment, that she was the only one of the party gazing in the direction of the shore which they had originally left, and she alone made the discovery that instantly turned all eyes in that direction. Exactly at the spot where they would have been landed by the Mohawk--allowing for the inevitable dropping down stream--was still another light, resembling the first that had startled them.
