"Ever see a chicken?" asked the Unwiseman.
"Yes," said Whistlebinkie.
"Well, a chicken's only an advanced egg," said the Unwiseman.
"That's true," said Mollie.
"And chickens haven't got anything but hind legs, have they?" demanded the old gentleman.
"Thass-a-fact," whistled Whistlebinkie.
"And Columbus proved it by making the egg stand up?" asked Mollie.
"That's what history tells us," said the Unwiseman. "All the Harvard and Yale professors of the day said the earth was flat, but Columbus knew better, so he just took an egg and proved it. That's one of the things I've put in a poem. Want to hear it?"
"Indeed I do," said Mollie. "It must be interesting."
