As it nears Cincinnati the Ohio narrows and deepens, and the banks rise more abruptly. Henry kept close to the southern shore, his body often touching the soft earth. Fortunately the bushes grew thickly, even on the steep cliff, to the water's edge. When he had gone three or four hundred yards he pulled in among them and lay still awhile. He heard the sound of distant shots and he knew that the Indians were still sniping the camp. The curve of the Ohio hid the boats of his friends, and before him the river seemed to be deserted. Yet he was sure that the Indian canoes were on watch. They might be hovering within fifty yards of him. He listened for the noise of paddles, but no such sound came, and pushing his tiny craft from the coil of bushes, he set out once more upon the Ohio. Still hearing and seeing nothing, he went a little faster. Henry was a powerful swimmer, and the raft, small as it was, gave him ample support. Meanwhile, he sought sedulously to avoid any noise, knowing that only an incautious splash made by his paddle would almost certainly be heard by an Indian ear. Presently he saw on the northern bank a light, and then another light farther up the stream. Probably the Indians were signaling to one another, but it did not matter to him, and he swam on towards the mouth of the Licking, now about a half mile away. Another hundred yards and he quickly and silently drew in to the bank again, pushing the raft far back, until it, as well as himself, was hidden wholly. He had heard the distant sounds of paddles coming in his direction, and soon two Indian canoes in file came in sight. Each canoe contained two warriors. Henry inferred from the way in which they scrutinized the river and the bank, that they were sentinels. Well for him that the bushes grew thick and high. The penetrating Indian eyes passed unsuspecting over his hiding place, and went on, dropping slowly down the river to a point where they could watch the white boats. A hundred yards in that darkness was sufficient to put them out of sight, and Henry again pushed boldly into the stream. The young blockade runner now had a theory that the sentinel boats of the Indians would keep close in to the shore. That would be their natural procedure, and to avoid them he swam boldly far out into the river. Near the middle of the current he paddled once more up stream. Only his head showed above the surface and the raft was so low that no one was likely to notice it. The wisdom of his movement soon showed as he made out three more canoes near the Kentucky shore, obviously on watch. Toward the north, at a point not more than seventy or eighty yards away he saw another canoe containing three warriors and apparently stationary. Others might be further ahead, but the darkness was too great for him to tell. Clearly, there was no passage except in the middle of the stream, the very point that he had chosen.
