This was as the red scout wanted matters arranged; and when he grasped the paddle it was with a greater confidence than he had felt at any time during the night. But he had entered upon one of the most perilous attempts conceivable, and he was sure the trick would be detected within the succeeding five minutes. In fact, it was discovered in less than that time; for he had no more than fairly dipped the oar in the water than he heard a low, vibrating whoop from the spot where the Mohawk was stationed. That sound, as Lena-Wingo well knew, meant danger, and was intended as a signal for his companions to hasten to the spot--a signal that was sure to be promptly obeyed when more than a half dozen were on the alert and waiting for just such a call. It was so distinct that the whites accepted it as evidence that their flight was discovered, and pursuit was sure to follow. Rosa was much frightened, for she felt they had gone so far that they could not return, and it was a question whether they would reach the other side of the river in safety, or be captured on the stream itself, with the probabilities in favor of the latter. Everything depended upon the skill and sagacity of the Mohawk, who showed himself equal to the occasion. At the same instant that the sound mentioned reached his ear, he dipped his paddle deep into the water, and sent the canoe, with one powerful sweep, several rods down the bank, keeping so close to the land that the leaves of the overhanging limbs brushed the heads of the occupants, and compelled them to duck their heads. This done, he allowed the boat to rest, while he listened to learn what his enemies were doing. The sounds that fell upon his ear told him the flight of the boat had been detected, and there could be no doubt that the whole force of Iroquois would be engaged in the hunt in the next few minutes. Without speaking, he dipped the paddle again, and the canoe was driven as far as before down the stream; but, in this instance, he did not permit it to rest, continuing the process until he had gone fully a hundred yards from his starting point. This done, he considered he had reached the point where he could make a change in the direction, and he headed boldly out into the river, aiming for the other shore, which had been their destination so long, and which he was determined to make this time. The skill with which he controlled and swayed the ashen blade was wonderful. The night was still, without a breath of air stirring the tree-tops, but the instant the boat left the cover of the bank, the faces of the whites were swept as if by a gale. At that rate, the other shore would be made in a very short time, and the action of the Mohawk indicated that such was his purpose, guided, perhaps, by the hope that it might be done before the alarm could reach those grouped on that side.
