Johnny slowly turned his head and looked at Peter as if he thought Peter had suddenly gone crazy. “What are you talking about, Peter Rabbit? I'm not a Squirrel; I'm a Woodchuck,” he replied.

“Just the same, you are a Squirrel,” retorted Peter. “The Woodchucks belong to the Squirrel family. Old Mother Nature says so, and if she says so, it is so. You'd better join our school, Johnny Chuck, and learn a little about your own relatives.”

Johnny Chuck blinked his eyes and for a minute or two couldn't find a word to say. He knew that if Peter were telling the truth as to what Old Mother Nature had said, it must be true that he was member of the Squirrel family. But it was hard to believe. “What is this school?” he finally asked.

Peter hastened to tell him. He told Johnny all about what he and Jumper the Hare had learned about their family, and all the surprising things Old Mother Nature had told them about the Squirrel family, and he ended by again urging Johnny Chuck to join the school and promised to call for Johnny the next morning.

But Johnny Chuck is lazy and does not like to go far from his own doorstep, so when Peter called the next morning Johnny refused to go, despite all Peter could say. Peter didn't waste much time arguing for he was afraid he would be late and miss something. When he reached the Green Forest he found his cousin, Jumper the Hare, and Chatterer the Red Squirrel, and Happy Jack the Gray Squirrel, already there. As soon as Peter arrived Old Mother Nature began the morning lesson.

“Happy Jack,” said she, “you may tell us all you know about your cousin, Chatterer.”

“To begin with, he is the smallest of the Tree Squirrels,” said Happy Jack. “He isn't so very much bigger than Striped Chipmunk, and that means that he is less than half as big as myself. His coat is red and his waistcoat white; his tail is about two-thirds as long as his body and flat but not very broad. Personally, I don't think it is much of a tail.”

At once Chatterer's quick temper flared up and he began to scold. But Old Mother Nature silenced him and told Happy Jack to go on. “He spends more of his time in the trees than I do,” continued Happy Jack, “and is especially fond of pine trees and other cone-bearing trees. He likes the deeper parts of the Green Forest better than I do, though he seems to feel just as much at home on the edge of the Green Forest, especially if it is near a farm where he can steal corn.”

Chatterer started to scold again but was silenced once more by Old Mother Nature. “I have to admit that Chatterer is thrifty,” continued Happy Jack, quite as if he hadn't been interrupted. “He is very fond of the seeds of cone-bearing trees. He cuts the cones from the trees just before they are ripe. Then they ripen and open on the ground, where he can get at the seeds easily. He often has a number of store-houses and stores up cone seeds, acorns, nuts, and corn when he can get it. He builds a nest of leaves and strips of bark, sometimes in a hollow tree and sometimes high up in the branches of an evergreen tree. He is a good jumper and jumps from tree to tree. He is a busybody and always poking his nose in where he has no business. He steals my stores whenever he can find them.”

“You do the same thing to me when you have the chance, which isn't often,” sputtered Chatterer.
