Billy Mink was coming down the bank of the Laughing Brook. Billy Mink was feeling very good indeed. He had had a good breakfast, the sun was warm, little white cloud ships were sailing across the blue sky and their shadows were sailing across the Green Meadows, the birds were singing and the bees were humming. Billy Mink felt like singing too, but Billy Mink's voice was not meant for singing.

By and by Billy Mink came to the Smiling Pool. Here the Laughing Brook stopped and rested on its way to join the Big River. It stopped its noisy laughing and singing and just lay smiling and smiling in the warm sunshine. The little flowers on the bank leaned over and nodded to it. The beech tree, which was very old, sometimes dropped a leaf into it. The cat-tails kept their feet cool in the edge of it.

Billy Mink jumped out on the Big Rock and looked down into the Smiling Pool. Over on a green lily pad he saw old Grandfather Frog.

"Hello, Grandfather Frog," said Billy Mink.

"Hello, Billy Mink," said Grandfather Frog. "What mischief are you up to this fine sunny morning?"

Just then Billy Mink saw a little brown head swimming along one edge of the Smiling Pool.

"Hello, Jerry Muskrat!" shouted Billy Mink.

"Hello your own self, Billy Mink," shouted Jerry Muskrat, "Come in and have a swim; the water's fine!"

"Good," said Billy Mink. "We'll have a swimming party."

So Billy Mink called all the Merry Little Breezes of Old Mother West Wind, who were playing with the flowers on the bank, and sent them to find Little Joe Otter and invite him to come to the swimming party. Pretty soon back came the Little Breezes and with them came Little Joe Otter.

"Hello, Billy Mink," said Little Joe Otter. "Here I am!"

"Hello, Little Joe Otter," said Billy Mink. "Come up here on the Big Rock and see who can dive the deepest into the Smiling Pool."

So Little Joe Otter and Jerry Muskrat climbed up on the Big Rock side of Billy Mink and they all stood side by side in their little brown bathing suits looking down into the Smiling Pool.

"Now when I count three we'll all dive into the Smiling Pool together and see who can dive the deepest. One!" said Billy Mink. "Two!" said Billy Mink. "Three!" said Billy Mink.

And when he said "Three!" in they all went head first. My such a splash as they did make! They upset old Grandfather Frog so that he fell off his lily pad. They frightened Mr. and Mrs. Trout so that they jumped right out of the water. Tiny Tadpole had such a scare that he hid way, way down in the mud with only the tip of his funny little nose sticking out.

"Chug-a-rum," said old Grandfather Frog, climbing out of his lily pad. "If I wasn't so old I would show you how to dive."

"Come on, Grandfather Frog!" cried Billy Mink. "Show us how to dive."

And what do you think? Why, old Grandfather Frog actually got so excited that he climbed up on the Big Rock to show them how to dive. Splash! Went Grandfather Frog into the Smiling Pool. Splash! Went Billy Mink right behind him. Splash! Splash! Went Little Joe Otter and Jerry Muskrat, right at Billy Mink's heels.

"Hurrah!" shouted Mr. Kingfisher, sitting on a branch of the old beech tree. And then just to show them that he could dive, too, splash! He went into the Smiling Pool.

Such a noise as they did make! All the Little Breezes of Old Mother West Wind danced for joy on the bank. Blacky the Crow and Sammy Jay flew over to see what was going on.

"Now let's see who can swim the farthest under water," cried Billy Mink.

So they all stood side by side on one edge of the Smiling Pool.

"Go!" shouted Mr. Kingfisher, and in they all plunged. Little ripples ran across the Smiling Pool and then the water became as smooth and smiling as if nothing had gone into it with a plunge.

Now old Grandfather Frog began to realize that he wasn't as young as he used to be, and he couldn't swim as fast as the others anyway. He began to get short of breath, so he swam up to the top and stuck just the tip of his nose out to get some more air. Sammy Jay's sharp eyes saw him.

"There's Grandfather Frog!" he shouted.

So then Grandfather Frog popped his head out and swam over to his green lily pad to rest.

Way over beyond the Big Rock little bubbles in three long rows kept coming up to the top of the Smiling Pool. They showed just where Billy Mink, Little Joe Otter and Jerry Muskrat were swimming way down out of sight. It was the air from their lungs making the bubbles. Straight across the Smiling Pool went the lines of little bubbles and then way out on the farther side two little heads bobbed out of water close together. They were Billy Mink and Little Joe Otter. A moment later Jerry Muskrat bobbed up beside them.

You see, they had swum clear across the Smiling Pool and of course they could swim no farther.

So Billy Mink's swimming party was a great success.
