Old Mother Nature shook her head. “You are wrong this time, Peter,” said she, and Peter looked as foolish as he felt. “Striped Chipmunk is a Rock Squirrel. Seek Seek the Spermophile who lives on the plains of the West and is often called Gopher Squirrel, is the true Ground Squirrel. Now I can't spend any more time with you little folks this morning, because I've too much to do. To-morrow morning I shall expect Chatterer to tell me all about Happy Jack, and Happy Jack to tell me all about Chatterer. Now scamper along, all of you, and think over what you have learned this morning.” So Peter and Jumper and Chatterer and Happy Jack thanked Old Mother Nature for what she had told them and scampered away. Peter headed straight for the far corner of the Old Orchard where he was sure he would find Johnny Chuck. He couldn't get there fast enough, for he wanted to be the first to tell Johnny Chuck that he was a Squirrel. You see he didn't believe that Johnny knew it. CHAPTER V The Squirrels of the Trees Peter Rabbit found Johnny Chuck sitting on his doorstep, sunning himself. Peter was quite out of breath because he had hurried so. “Do you know that you are a Squirrel, Johnny Chuck?” he panted. 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.”
