Why, they found their boxes empty! The nuts were all gone!
"Some one bad has been here," said Peter.
Polly laughed. "You always say that, Peter. I think it was those squirrels. And I don't care, because they need the nuts to eat this winter."
"I don't care, either," said Peter. "I think we forgot to lock our boxes."
"Perhaps we did," said Polly. "But I guess the squirrels thought the boxes were theirs. When they called for their mail, they found the boxes full. How pleased they must have been! Let's pick up more nuts for them."
So the children again filled the post-office boxes with nuts. Then they went home and left them for the squirrels.

One day Peter saw something that pleased him. It was a branch of red leaves on a maple tree.
