"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.
