Two Horses were drawing their carts. The Front Horse pulled well, but the Hind Horse kept stopping all the time. The load of the Hind Horse was transferred to the front cart; when all was transferred, the Hind Horse went along with ease, and said to the Front Horse:
"Work hard and sweat! The more you try, the harder they will make you work."
When they arrived at the tavern, their master said:
"Why should I feed two Horses, and haul with one only? I shall do better to give one plenty to eat, and to kill the other: I shall at least have her hide."
So he did.
