There was nothing but mountain peaks as far as the eye could reach. The sides of the mountains were covered with timber, and that timber made a never-to-be-forgotten impression on Bill. It spread over the undulating ground like a rich, velvety, green rug. Clearings were few and far between. The streams and rivers wound their way through the valleys, making the rolling green covering even more beautiful. It was hard to believe that the trees over which he was flying were two or three hundred feet high.
