Peter sat bolt upright with his eyes very wide open. In them was a funny look of surprise as he stared up at Jenny Wren. “What are you talking about, Jenny Wren?” he demanded. “Don't you know that none of the Rabbit family swim unless it is to cross the Laughing Brook when there is no other way of getting to the other side, or when actually driven into the water by an enemy from whom there is no other escape? I can swim a little if I have to, but you don't catch me in the water when I can stay on land. What is more, you won't find any other members of my family doing such a thing.” “Tut, tut, tut, tut, Peter!” exclaimed Jenny Wren in her sharp, scolding voice. “Tut, tut, tut, tut! For a fellow who has been so curious about the ways of his feathered neighbors, you know very little about your own family. If I were in your place I would learn about my own relatives before I became curious about my neighbors. How many relatives have you, Peter?” “One,” replied Peter promptly, “my big cousin, Jumper the Hare.” Jenny Wren threw back her head and laughed and laughed and laughed. It was a most irritating and provoking laugh. Finally Peter began to lose patience. “What are you laughing at?” he demanded crossly. “You know very well that Jumper the Hare is the only cousin I have.” Jenny Wren laughed harder that ever. “Peter!” she gasped. “Peter, you will be the death of me. Why, down in the Sunny South, where I spent the winter, you have a cousin who is more closely related to you than Jumper the Hare. And what is more, he is almost as fond of the water as Jerry Muskrat. He was called the Marsh Rabbit or Marsh Hare, and many a time I have watched him swimming about by the hour.” “I don't believe it!” declared Peter angrily. “I don't believe a word of it. You are simply trying to fool me, Jenny Wren. There never was a Rabbit and there never will be a Rabbit who would go swimming for the fun of it. I belong to the Cottontail branch of the Hare family, and it is a fine family if I do say so. My cousin Jumper is a true Hare, and the only difference between us is that he is bigger, has longer legs and ears, changes the color of his coat in winter, and seldom, if ever, goes into holes in the ground. The idea of trying to tell me I don't know about my own relatives.” Jenny Wren suddenly became sober. “Peter,” said she very earnestly, “take my advice and go to school to Old Mother Nature for awhile. What I have told you is true, every word of it. You have a cousin down in the Sunny South who spends half his time in the water. What is more, I suspect that you and Jumper have other relatives of whom you've never heard. Such ignorance would be laughable if it were not to be pitied. This is what comes of never having traveled. Go to school to Old Mother Nature for a while, Peter. It will pay you.” With this, Jenny Wren flew away to hunt for Mr. Wren that they might decide where to make their home for the summer.
