"Quite a while," replied Grandfather Frog. "Quite a while. Perhaps you would like to hear about it."

"Oh, if you please, Grandfather Frog," cried Peter. "If you please. I should love dearly to hear about it. Perhaps then I can learn to swim."

Grandfather Frog snapped up a foolish green fly that happened his way, and Peter heard something that sounded very much like a chuckle. He looked at Grandfather Frog suspiciously. Was that chuckle because of the foolish green fly, or was Grandfather Frog laughing at him? Peter wasn't sure.

"It all happened a long time ago when the world was young, as a great many other things happened," began Grandfather Frog. "Old Mr. Mink, the ever-so-great-grandfather of Billy Mink, couldn't do all the things that Billy can now. For instance, he couldn't swim. But he could do a great many things, and he was very smart. It has always run in the Mink family to be smart. He dressed very much as Billy does now, except that he didn't have the waterproof coat that Billy has. And he was a great traveler, just as Billy is. Everybody smaller than he and some who were bigger were a little bit afraid of old Mr. Mink, for he was quite as sly and cunning as Mr. Fox, and it was suspected that he knew a great deal more than he ever admitted about eggs that were stolen and nests that were broken up, and other strange things that happened in the Green Forest and along the Laughing Brook. But he never was caught doing anything wrong and always seemed to be minding his own business, so, all things considered, he got along very well with his neighbors.

"Now Mr. Mink was small and spry, and his wits were as nimble as his feet. He saw all that was going on about him, and he was wise enough to keep his tongue still, so that it never got him into trouble as gossipy tongues do some people I know."

Peter Rabbit fidgeted uneasily. It seemed to him that Grandfather Frog had looked at him very hard when he said this. But Grandfather Frog just cleared his throat and went on with his story.

"Yes, Sir, old Mr. Mink kept his eyes wide open and his ears wide open and the wits in his little brown head always working. He noticed that those who were fussy about what they ate and insisted on having a special kind of food often went hungry or had to hunt long and hard to find what they liked, so he made up his mind to learn to eat many kinds of food. This is how it happens that he learned to like fish. His big cousin, Mr. Otter, often caught a bigger fish than he could eat all himself and would leave some of it on the bank. Mr. Mink would find it and help himself.

"But having to depend on Mr. Otter to get the fish for him didn't suit Mr. Mink at all. In the first place, he didn't have as much as he wanted. And then again he didn't have it when he wanted it. 'If I could learn to catch fish for myself, I would be much better off,' thought Mr. Mink. After this he spent a great deal of time on the banks of the Smiling Pool watching Mr. Otter swim to see just how he did it. 'If he can swim, I can swim,' said Mr. Mink to himself, and went off up the Laughing Brook to a quiet little pool where the water was not deep.

"At first he didn't like it at all. The water got in his ears and up his nose and choked him. And then it was so dreadfully wet! But he would grit his teeth and keep at it. After a while he got so that he could paddle around a little. Gradually he lost his fear of the water. Then he found that because he naturally moved so quickly he could sometimes catch foolish minnows who swam in where the water was very shallow. This was great sport, and he quite often had fish for dinner now.

"But he wasn't satisfied. No, Sir, he wasn't satisfied. Whatever Mr. Mink did, he wanted to do well. He could run well and climb well, and there was no better hunter in all the Green Forest. He was bound that he would swim well. So he kept trying and trying. He learned to fill his lungs with air and hold his breath for a long time, while he swam as fast as ever he could with his head under water as he had seen his cousin, Mr. Otter, swim. The more he did this, the longer he could hold his breath. After a while he found that because he was slim and trim and moved so fast, he could out-swim Mr. Muskrat, and this made him feel very good indeed, for Mr. Muskrat spent nearly all his time in the water and was accounted a very good swimmer. There was only one thing that bothered Mr. Mink. The water was so dreadfully wet! Every time he came out of it, he had to run his hardest to dry off and keep from getting cold. This was very tiresome and he did wish that there was an easier way of drying off.
