Paddy slipped into the water, where for a second or two he floated with just his head above the surface. Then he quickly raised his broad, heavy tail and brought it down on the water with a slap that sounded like the crack of a terrible gun. It was so loud and unexpected that every one save Old Mother Nature and Prickly Porky jumped with fright. Peter Rabbit happened to be right on the edge of the dam and, because he jumped before he had time to think, he jumped right into the water with a splash. Now Peter doesn't like the water, as you know, and he scrambled out just as fast as ever he could. How the others did laugh at him. “What did he do that for?” demanded Peter indignantly. “To show you one use he has for that handy tail,” replied Old Mother Nature. “That is the way he gives warning to his friends whenever he discovers danger. Did you notice how he used his tail to aid him in swimming? He turns it almost on edge and uses it as a rudder. Those big, webbed hind feet are the paddles which drive him through the water. He can stay under water a long time--as much as five minutes. See, he has just come up now.” Sure enough, Paddy's head had just appeared clear across the pond almost to the opposite shore, and he was now swimming on the surface. Old Mother Nature at once led the way around the pond to a small grove of poplar trees which stood a little way back from the water. Paddy was already there. “Now,” said Old Mother Nature “show us what kind of a lumberman you are.” Paddy picked out a small tree, sat up much as Happy Jack Squirrel does, but with his big flat tail on the ground to brace him, seized the trunk of the tree in both hands, and went to work with his great orange-colored cutting teeth. He bit out a big chip. Then another and another. Gradually he worked around the tree. After a while the tree began to sway and crack. Paddy bit out two or three more chips, then suddenly slapped the ground with his tail as a warning and scampered back to a safe distance. He was taking no chances of being caught under that falling tree. The tree fell, and at once Paddy returned to work. The smaller branches he cut off with a single bite at the base of each. The larger ones required a number of bites. Then he set to work to cut the trunk up in short logs. At this point Old Mother Nature interrupted. “Now show us,” said she, “what you do with the logs.” Paddy at once got behind a log, and by pushing, rolled it ahead of him until at last it fell with a splash in the water of a ditch or canal which led from near that grove of trees to the pond. Paddy followed into the water and began to push it ahead of him towards the pond. “That will do,” spoke up Old Mother Nature. “Come out and show us how you take the branches.”
