Old Grandfather Frog sat on his big green lily pad in the Smiling Pool dreaming of the days when the world was young and the frogs ruled the world. His hands were folded across his white and yellow waistcoat. Round, red, smiling Mr. Sun sent down his warmest rays on the back of Grandfather Frog's green coat.  
Very early that morning Old Mother West Wind, hurrying down from the Purple Hills on her way to help the white-sailed ships across the great ocean, had stopped long enough to blow three or four fat, foolish, green flies over to the big lily pad, and they were now safely inside the white and yellow waistcoat. A thousand little tadpoles, the great, great-grandchildren of Grandfather Frog, were playing in the Smiling Pool, and every once in a while wriggling up to the big lily pad to look with awe at Grandfather Frog and wonder if they would ever be as handsome and big and wise as he.
 
And still old Grandfather Frog sat dreaming and dreaming of the days when all the frogs had tails and ruled the world.
 
Presently Billy Mink came hopping and skipping down the Laughing Brook. Sometimes he swam a little way and sometimes he ran a little way along the bank, and sometimes he jumped from stone to stone. Billy Mink was feeling very good—very good indeed. He had caught a fine fat trout for breakfast. He had hidden two more away for dinner in a snug little hole no one knew of but himself. Now he had nothing to do but get into mischief. You can always depend upon Billy Mink to get into mischief. He just can't help it.
 
So Billy Mink came hopping and skipping down the Laughing Brook to the Smiling Pool. Then he stopped, as still as the rock he was standing on, and peeped through the bulrushes. Billy Mink is very cautious, very cautious indeed. He always looks well before he shows himself, that nothing may surprise him.
 
So Billy Mink looked all over the Smiling Pool and the grassy banks. He saw the sunbeams dancing on the water. He saw the tadpoles having such a good time in the Smiling Pool. He saw the Merry Little Breezes kissing the buttercups and daisies on the bank, and he saw old Grandfather Frog with his hands folded across his white, and yellow waistcoat sitting on the green lily pad, dreaming of the days when the world was young.
 
Then Billy Mink took a long breath, a very long breath, and dived into the Smiling Pool. Now, Billy Mink can swim very fast, very fast indeed. For a little way he can swim even faster than Mr. Trout. And he can stay under water a long time.
 
Straight across the Smiling Pool, with not even the tip of his nose out of water, swam Billy Mink. The thousand little tadpoles saw him coming and fled in all directions to bury themselves in the mud at the bottom of the Smiling Pool, for when he thinks no one is looking Billy Mink sometimes gobbles up a fat tadpole for breakfast.
 
Straight across the Smiling Pool swam Billy Mink toward the big green lily pad where Grandfather Frog sat dreaming of the days when the world was young. When he was right under the big green lily pad he suddenly kicked up hard with his hind feet. Up went the big green lily pad, and, of course, up went Grandfather Frog—up and over flat on his back, with a great splash into the Smiling Pool!
 
Now, Grandfather Frog's mouth is very big. Indeed, no one else has so big a mouth, unless it be his cousin, old Mr. Toad. And when Grandfather Frog went over flat on his back, splash in the Smiling Pool, his mouth was wide open.
 
You see he was so surprised he forgot to close it. So, of course, Grandfather Frog swallowed a great deal of water, and he choked and spluttered and swam around in foolish little circles trying to find himself. Finally he climbed out on hi............
