the spring fever in his bones and had
gone up and down the Laughing Brook, poking into all kinds of places
just for the fun of seeing new things. Little Joe Otter had been more
full of fun than ever, if that were possible. Mr. and Mrs. Redwing had
come back to the bulrushes from their winter home way down in the warm
Southland. Everybody was happy, just as happy as could be.

One sunny morning Jerry Muskrat sat on the Big Rock in the middle of the
Smiling Pool, just thinking of how happy everybody was and laughing at
Little Joe Otter, who was cutting up all sorts of capers in the water.
Suddenly Jerry's sharp eyes saw something that made him wrinkle his
forehead in a puzzled frown and look and look at the opposite bank.
Finally he called to Little Joe Otter.

"Hi, Little Joe! Come over here!" shouted Jerry.

"What for?" asked Little Joe, turning a somersault in the water.

"I want you to see if there is anything wrong with my eyes," replied
Jerry.

Little Joe Otter stopped swimming and stared up at Jerry Muskrat. "They

Little Joe Otter looked again and his eyes opened wide. "You are right,
Jerry Muskrat!" he cried. "There's nothing the matter with your eyes.
The water is as low as it ever gets, even in the very middle of summer.
What can it mean?"

"I don't know," replied Jerry Muskrat. "It is queer! It certainly is
very queer! Let's go ask Grandfather Frog. You know he is very old and
very wise, so perhaps he can tell us what it means."

Splash! Jerry Muskrat and Little Joe Otter dived into the Smiling Pool
and started a race to see who could reach Grandfather Frog first. He
was sitting among the bulrushes on the edge of the Smiling Pool, for the
lily-pads were not yet big enough for him to sit on comfortably.

"Oh, Grandfather Frog, what's the matter with the Smiling Pool?" they
shouted, as they came up quite out of breath.

"Chugarum! There's nothing the matter with the Smiling Pool; it'
