With that he started to follow the little stream which ran gurgling down into the Green Forest. He had followed that little stream more than once, and now he found it just as he remembered it. The farther it ran, the larger it grew, until at last it became the Laughing Brook, merrily tumbling over rocks and making deep pools in which the trout loved to hide. At last he came to the edge of a little open hollow in the very heart of the Green Forest. He knew what splendid deep holes there were in the Laughing Brook here, and how the big trout loved to lie in them because they were deep and cool. He was thinking of these trout now and wishing that he had brought along his fishing-rod. He pushed his way through a thicket of alders and then--Farmer Brown's boy stopped suddenly and fairly gasped! He had to stop because there right in front of him was a pond! He rubbed his eyes and looked again. Then he stooped down and put his hand in the water to see if it was real. There was no doubt about it. It was real water,--a real pond where there never had been a pond before. It was very still there in the heart of the Green Forest. It was always very still there, but it seemed stiller than usual as he tramped around the edge of this strange pond. He felt as if it were all a dream. He wondered if pretty soon he wouldn't wake up and find it all untrue. But he didn't, and so he kept on tramping until presently he came to a dam,--a splendid dam of logs and sticks and mud. Over the top of it the water was running, and down in the Green Forest below he could hear the Laughing Brook just beginning to laugh once more. Farmer Brown's boy sat down with his elbows on his knees and his chin in his hands. He was almost too much surprised to even think. [Illustration] VIII PETER RABBIT GETS A DUCKING Farmer Brown's boy sat with his chin in his hands staring at the new pond in the Green Forest and at the dam which had made it. That dam puzzled him. Who could have built it? What did they build it for? Why hadn't he heard them chopping? He looked carelessly at the stump of one of the trees, and then a still more puzzled look made deep furrows between his eyes. It looked--yes, it looked very much as if teeth, and not an axe, had cut down that tree. Farmer Brown's boy stared and stared, his mouth gaping wide open. He looked so funny that Peter Rabbit, who was hiding under an old pile of brush close by, nearly laughed right out. But Peter didn't laugh. No, Sir, Peter didn't laugh, for just that very minute something happened. Sniff! Sniff! That was right behind him at the very edge of the old brush-pile, and every hair on Peter stood on end with fright.
