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.

This was complicating matters, indeed, and the alarm of the whites became greater than at any time since starting. It looked as if they had not only been detected, but that the Iroquois had quietly perfected their preparations for capturing them. The Mohawk, as was his peculiarity under all circumstances, was as cool as ever, and he looked back and forth as if not particularly desirous of learning who were the torch-bearers.

"Don't stand up," he whispered, fearing that some of his companions would rise to their feet in their excitement.

There was a possibility that the fugitives had not been detected, though the probabilities were against such a hopeful fact. It would have seemed to an uninterested spectator that if the Iroquois were aware that the party whom they were seeking had embarked, they would have kept them under surveillance until they learned where they were likely to land, and then would have made preparations to capture them as they left the boat. Such was the simplest plan, and it would have been more effective than any other. That they had neglected to do so was ground for the hope of the Mohawk that he and his friends were still undiscovered.

It was equally probable that the redmen on the southeastern shore, having learned that their game was coming into their hands, had signaled the fact to their allies across the Susquehanna, so that they might be prepared for the retrograde movement which was actually made. Under the circumstances, there was but one thing remaining for the Mohawk to do, and that was to drift with the current until below the point where the last light had shown itself, and then to make an effort to land. Fortunately, the woods were dense at this place, so that if they could secure a foothold once more, there was a good prospect that this natural protection could be turned to account. And this was what the guide now attempted to do.

Stooping low in the boat, so that his head and shoulders barely appeared above the gunwale, he held the pole ready to use any instant it might be required, and patiently awaited the moment when the flat-bottomed craft should reach the point desired. The excitement was the more intense because none dared move, and all were in a state of expectancy that made the suspense of the most trying nature. It seemed to the whites as they peeped cautiously over the low gunwale of the scow, that the moon threw double the light that it did when they were in the middle of the river and anxious to gain a view of the land they were seeking to reach. Again and again Rosa was sure she saw shadowy figures stealing along in the darkness, watching them with the keenness of so many lynxes, and quite as frequently she was equally sure she detected stealthy movements by the sound of the moccasin-covered feet on the bank.

Before they were a dozen feet below the point where the light was seen, it vanished from sight and the gloom enveloped them on every hand. While this was taken as another ominous sign by the whites, the Mohawk did not accept it as such. If the torches were meant as signals, nothing was more natural than that, having performed their duty, they should be withdrawn. The four parties in the scow maintained their cramped positions until the boat was a hundred yards below where the alarming light was seen. At this time, the Mohawk rose partly to his feet still keeping the greater portion of his body concealed, and the pole was carefully thrust over the side into the water.

No noise accompanied the cautious movement, but the others noticed that the boat felt the impulse at once. Lena-Wingo was using it for its legitimate purpose, and was gradually, but none the less certainly, working in toward the land. It seemed to the others that such a proceeding was dangerous in the highest degree, for the boat, on account of its size, was likely to attract attention. It was impossible that the others should keep their own persons out of sight when the situation was so critical. Ned and Jo closed their hands upon their rifles, ready to use them at an instant's notice, for to them nothing was more probable than that they would be called upon to resist an attack as soon as, if not before, they placed their feet on the shore.

When they were within a rod or so, the Mohawk ceased work with the pole, and devoted himself to listening for a short time. Unlike the others, he did not confine his observations to a single spot, but peered toward every point of the compass, on the watch for some canoe creeping down upon them from the other side of the stream. His keen vision was unable to detect anything upon the surface of the stream itself, but he saw once more the light that had caused them to turn back from landing. It was in very nearly the same spot, too, where it was first seen, and, what was more, it was moving precisely as if intended to convey a hasty message to parties on the opposite side the stream.

Lena-Wingo studied the action closely, for he was capable of reading many of the signs of the Iroquois unknowable to others, and there was a chance for him to gain important information. The torch was not merely vibrating as if carried by a person walking along the margin of the river, but it was swung round in a circle, slowly and impressively, beginning in this fashion, and increasing until it resembled a fiery wheel. Suddenly it disappeared, and all was darkness and stillness again on both sides of the Susquehanna.

"The whites and the Mohawk scout are on the river, and will try to return to the shore which they left."

This was the interpretation of Lena-Wingo, and it was about impossible for him to make any mistake. The retrogression of the fugitives had been detected, and the confederates on the bank toward which they were working their way were notified to be prepared for their coming. Certainly it was high time that the little party in the scow looked to what they were doing.
