The coming of the darkness did not stop the boy. He swung a little farther out into the stream, where the bushes and hanging boughs would not get in his way, and continued his course with some increase of speed. The great paddle swung swiftly through the water, and the length of stroke was amazing, but the boy's breath did not come faster, and the muscles on his arms and shoulders rippled as if it were the play of a child. Henry was in waters unknown to him. He had nothing more than hearsay upon which to rely, and he used all the wilderness caution that he had acquired through nature and training. He called into use every faculty of his perfect physical being. His trained eyes continually pierced the darkness. At times, he stopped and listened with ears that could hear the footfall of the rabbit, but neither eye nor ear brought report of anything unusual. The river flowed with a soft, sighing sound. Now and then a wild creature stirred in the forest, and once a deer came down to the margin to drink, but this was the ordinary life of the woods, and he passed it by. He went on, hour after hour. The river narrowed. The banks grew higher and rockier, and the water, deep and silvery under the moon, flowed in a somewhat swifter current. Henry gave a little stronger sweep to the paddle, and the speed of the canoe was maintained. He still kept within the shadow of the northern bank. He noticed after a while that fleecy vapor was floating before the moon. The night seemed to be darkening, and a rising wind came out of the southwest. The touch of the air on, his face was damp. It was the token of rain, and he felt that it would not be delayed long. It was no part of his plan to be caught in a storm on the Monongahela. Besides the discomfort, heavy rain and wind might sink his frail canoe, and he looked for a refuge. The river was widening again, and the banks sank down until they were but little above the water. Presently he saw a place that he knew would be suitable, a stretch of thick bushes and weeds growing into the very edge of the water, and extending a hundred yards or more along the shore. He pushed his canoe far into the undergrowth, and then stopped it in shelter so close that, keen as his own eyes were, he could scarcely see the main stream of the river. The water where he came to rest was not more than a foot deep, but he remained in the canoe, half reclining and wrapping closely around himself and his rifle a beautiful blanket woven of the tightest fiber.
