Aesop's tales # 29 - The Hare and the Hound
A Hound started a Hare from his lair, but after
a long run, gave up the chase. A goat-herd seeing him stop, mocked him, saying,
"The little one is the best runner of the two." The Hound replied,
"You do not see the difference between us: I was only running for a
dinner, but he for his life."
Moral: Incentive spurs effort.
