They struck directly for the top of the knob, as the ranger had told them to do. The slope of the ground alone guided them. So dense was the stand of timber that the huge trunks shut off the view in all directions. It was almost as though they were encircled by palisades. And so thick was the shade that rarely did a sunbeam reach the earth. They were in the forest primeval, a land of perpetual gloom. There was no underbrush and they could travel rapidly. In a very short time they came to the top of the knob. The summit had been entirely cleared of timber. On the very highest point one lone tree remained. A long pole had been planted near its trunk, with its top fastened to a branch of the tree. Crossbars between the tree and the pole made a sort of rude ladder of the affair. And well up the tree a rough staging had been constructed of small limbs. The boys saw at once that this was a rude sort of watch-tower, and they suspected that the ranger had been in the tree when he discovered the smoke from their fire. They climbed up the tree and surveyed the scene before them in silence. Indeed, it was too sublime for words. On every side stretched the forest. Mile upon mile, league after league, east, west, north, south, far as the eye could reach, spread the leafy roof of the forest, seemingly illimitable, boundless, vast as the ocean, a sea of trees. And like a sea the forest rose and fell in huge billows. On either hand great mountains reared their huge bulk heavenward. Beyond them other ranges heaved their rugged crests aloft. And still other ranges lay beyond these. Over all was a cover of living green, the canopy of the forest. Sublime, majestic, awesome, almost overpowering was the spectacle. And neither lad could find words to express the emotion that arose within him. So they stood and looked in silent wonder. Finally Charley spoke. "It's worth all we've been through, Lew, just to see this," he said. "I shall be well paid for the trip, even if we never get a fish." Presently Lew looked up at the sun. Then he examined the mountains a little to the left of the sun. "There's where we go," he said, pointing over the nearest ridge to a gap in the mountain beyond it. "The trout-stream will be in the third valley. We've got to travel due east. And it will be some hike, too--over a mountain and through a high gap. Let's pick out our landmarks and get under way. It will take us a good many hours to make it, but we ought to be there in time to have trout for supper." For a few moments the boys examined the way in silence. "See that bunch of rocks on the summit?" asked Lew. "They look like chimney-rocks from here. Anyway, they stick up higher than any other part of the mountain. And there's three tall pines right beside them. That's a good landmark. It's exactly in a straight line for the gap. We can find that mark if we can find anything. But you can't see very clearly through this timber. Was there ever anything like it?"
