Grandfather Frog looked immensely pleased. It always pleases him to be considered wise. "Chug-a-rum!" said he gruffly. "You have a very smooth tongue, Jimmy Skunk. But what is this matter on which you cannot agree?"

"How many animals can fly?" returned Jimmy, by way of answer.

"One," replied Grandfather Frog. "I thought everybody knew that. Flitter the Bat is the only animal who can fly."

"You forget Timmy, the Flying Squirrel!" cried Peter excitedly. "That makes two."

Grandfather Frog shook his head. "Peter, Peter, whatever is the matter with those eyes of yours?" he exclaimed. "They certainly are big enough. I wonder if you ever will learn to use them. Half-seeing is sometimes worse than not seeing at all. Timmy cannot fly any more than I can."

"What did I tell you?" cried Jimmy Skunk triumphantly.

"But I've seen him fly lots of times!" persisted Peter. "I guess that any one who has envied him as often as I have ought to know."

"Hump!" grunted Grandfather Frog. "I guess that's the trouble. There was so much envy that it got into your eyes, and you couldn't see straight. Envy is a bad thing."

Jimmy Skunk chuckled.

"Did you ever see him away from trees?" continued Grandfather Frog.
