One reason Peter is so fond of Mr. and Mrs. Quack is because they always have a story for him. Sometimes it is a story of adventure, a tale of terrible danger and narrow escapes. Sometimes it is about their home in the far Northland, and again it is about the wonderful Southland where they spend the winter. But the story that Peter likes best is the one about where and how the Quack family got their funny, webbed feet. Mr. Quack doesn't think those feet funny at all, but Peter does. He never grows tired of watching Mr. and Mrs. Quack use them, because, you know, they are used so differently from other feet. And always he goes back to the dear Old Briar-patch with renewed admiration for the wisdom of Old Mother Nature.

Peter noticed those feet the first time he met Mr. and Mrs. Quack. He couldn't help but notice them. It happened that Mr. and Mrs. Quack were out on the bank of the Smiling Pool as Peter came hurrying over in his usual way, lipperty-lipperty-lip. They heard him coming and not knowing at first who it was they at once started for the water. Peter never will forget the funny way in which they waddled. He never had seen anybody quite so awkward. But when they reached the water he forgot to laugh. He simply stared open-mouthed in astonishment. You see there they were as graceful as they had been awkward on land. Afterward, when Peter had become acquainted with them and they were the best of friends, he ventured to speak of their queer feet.

"Do you know," said he, "you have the most interesting feet of anybody I know of. They are so broad that the first time I saw them I couldn't believe my own eyes. I didn't suppose anybody had such broad feet. I suppose there is some special reason why they are so broad and why your legs are so short. Do you know how Mother Nature happened to give you feet so different from the feet of other birds, Mr. Quack?"

Mr. Quack chuckled. "I tell you what it is, Peter," said he, "if you'll tell me why it is you have such long hind legs and such a funny short tail, I'll tell you why it is that Mrs. Quack and I have such broad feet, though I must confess that I don't see anything odd about them."

Peter agreed at once. He told Mr. and Mrs. Quack all about what happened to his grandfather a thousand times removed, the very first Rabbit, way back when the world was young, and how ever since then all Rabbits have had long hind legs and short tails. When he had finished Mr. Quack thoughtfully scratched his handsome green head, looked at his reflection in the Smiling Pool to make sure that he was looking his very best, looked behind to see that the feathers in the tip of his tail had the proper curl, and then gazed off over the Green Meadows with a far-away look in his eyes as if he were looking way back to the time he was to tell about. At last, just as Peter Rabbit was beginning to lose patience Mr. Quack began.

"It must be, Peter," said he, "that my great-great-ever-so-great-grandfather lived just about the same time as your great-great-ever-so-great-grandfather, way back in the days when the world was young. Perhaps they knew each other. Perhaps they were acquainted just as you and I are now. Anyway, according to what has been handed down in the family, Grandfather Quack was very much such a looking fellow as I am now, except in the matter of his bill and feet. His bill was not broad like mine but more like the bills of other birds, and his feet were like the feet of Mr. Grouse and Bob White. They were made for scratching, and there was nothing between the toes. You see, Old Mother Nature was experimenting. She made everybody a little different from everybody else and then started them forth in the Great World to shift for themselves and to find out what they really needed that they hadn't got.

"Old Mr. Quack, my great-great-ever-so-great-grandfather, soon discovered one thing, and that was that his legs were too short for him to get around very fast. When he walked, everybody laughed at him. When he tried to run, they laughed harder than ever. He didn't mind this so very much, though he did a little. Nobody likes to be laughed at, especially when it is because of something they cannot help. But what he did mind was the fact that his neighbors could run about so much faster than he that they got all the best of the food, and quite often he went hungry.

"One day he happened to be sitting on the bank of the Smiling Pool, thinking the matter over and wondering what he had best do, when Mr. Fox stole up behind him and startled him so that he lost his balance and tumbled down the bank into the water. This frightened him more than ever, and he flapped about and squawked and squawked and flapped until Mr. Fox nearly split his sides laughing at him. And when he was quite out of breath, Mr. Quack discovered that he was making all this fuss for nothing. He didn't sink, but floated on the water, and what was more the water didn't get under his feathers at all. When he tried to walk, of course he couldn't, and he had a funny feeling because his feet didn't touch anything and felt so very useless. But he kept moving them back and forth, and pretty soon he discovered that he moved ahead. Of course he moved very slowly, because his feet were not made for use in the water, but he moved, and that was enough. He knew then that he could get back to land. Then he tried his wings and he found that he could rise into the air from the water quite as easily as from the land. Right then and there all fear of the water left him. In fact, he liked it.

"Little by little, Grandfather Quack began to understand that he had made a great discovery. He had discovered the safest place in all the Great World for him. Out on the water he was safe from Mr. Fox and Mr. Wolf and all the other four-footed hunters. So he took to spending most of his time on the water or near it. When he wanted a nap, he would hide among the rushes that grew in the water. 'If only I didn't have to leave the water for food!' sighed Grandfather Quack. 'If only I could find food here, I would never leave the water.'

"At the time he was squatting at the very edge of the Smiling Pool. Presently he noticed a funny water bug crawling on the bottom where the water was only an inch or two deep. 'I wonder if that fellow is good to eat,' thought he, and almost without thinking he plunged his head under water and caught the bug. It was good. Grandfather Quack at once started to look for more, and while doing this he discovered that there were a great many seeds from the rushes scattered about in the mud at the bottom of the Smiling Pool, and that these also were good to eat. Then quite by accident he got hold of a tender root in the mud and found that this was especially good.
