"Well," said Grandfather Frog, settling himself in a way that Peter knew meant a story, "of course Drummer over there came by his red cap because it was handed down in the family, but of course there's a reason."

"Of course," said Peter, quite as if he knew all about it.

Grandfather Frog rolled his great, goggly eyes and looked at Peter suspiciously, but Peter looked so innocent and eager that he went on with his story.

"Of course, it all happened way back in the days when the world was young."

"Of course!" said Peter.

This time Grandfather Frog took no notice. "Drummer's grandfather a thousand times removed was just a plain little black and white bird without the least bit of bright color on him. He didn't have any sweeter voice than Drummer has to-day. Altogether he seemed to his neighbors a no-account little fellow, and they didn't have much to do with him. So Mr. Woodpecker lived pretty much alone. In fact, he lived alone so much that when he found a hollow tree he used to pound on it just to make a noise and keep from being lonesome, and that is how he learned to drum. You see, he hadn't any voice for singing, and so he got in the habit of drumming to keep his spirits up.

"Now all the time, right down in his heart, Mr. Woodpecker envied the birds who had handsome coats. He used to wish and wish that he had something bright, if it were no more than a pretty necktie. But he never said anything about it, and no one suspected it but Old Mother Nature, and Mr. Woodpecker didn't know that she knew it. Whenever he got to wishing too much, he would try to forget it by hunting for worms that bored into the trees of the Green Forest and which other birds could not get because they did not have the stout bill and the long tongue Mr. Woodpecker possessed.

"Now it happened that while Old Mother Nature was busy elsewhere, a great number of worms settled in the Green Forest and began to bore into the trees, so that after a while many trees grew sickly and then died. None of the other little people seemed to notice it, or if they did, they said it was none of their business and that Old Mother Nature ought to look out for such things. They shrugged their shoulders and went on playing and having a good time. But Mr. Woodpecker was worried. He loved the Green Forest dearly, and he began to fear that if something wasn't done, there wouldn't be any Green Forest. He said as much to some of his neighbors, but they only laughed at him. The more he thought about it, the more Mr. Woodpecker worried.

"'Something must be done,' said he to himself. 'Yes, Sir, something must be done. If Old Mother Nature doesn't come to attend to things pretty soon, it will be too late.' Then he made up his mind that he would do what he could. From early morning until night he hunted worms and dug them out of the trees. He would start at the bottom of a tree and work up, going all over it until he was sure that there wasn't another worm left. Then he would fly to the next tree. He pounded with his bill until his neck ached. He didn't even take time to drum. His neighbors laughed at him at first, but he kept right on working, working, working every hour of the day.

"At last Old Mother Nature appeared very unexpectedly. She went all through the Green Forest, and her sharp eyes saw all that Mr. Woodpecker had done. She didn't say a word to him, but she called all the little people of the Green Forest before her, and when they were all gathered around, she sent for Mr. Woodpecker. She made him sit up on a dead limb of a tall chestnut-tree where all could see him. Then she told just what he had done, and how he had saved the Green Forest, and how great a debt the other little people owed to him.
