A Lion and a Bear found the carcase of a Fawn, and had a long fight for it. The contest was so hard and even, that, at last, both of them, half-blinded and half-dead, lay panting on the ground, without strength to touch the prize that was stretched between them. A Fox coming by at the time, and seeing their helpless condition, stepped in between the combatants and carried off the booty. "Poor creatures that we are," cried they, "who have been exhausting all our strength and injuring one another, merely to give a rogue a dinner!"
