There are many mice in a house. The man of the house gets a cat. The cat kills many of the mice. The oldest mouse says, "All the mice must come to my room and we will think what we can do about this cat."

All the mice come. Many mice speak, but none knows what to do. At last a young mouse stands up and says, "We must put a bell on that cat. Then the cat will not catch any more mice." Then the old mouse asks, "Who will put the bell on the cat?" No mouse answers. At last he says, "It is easy to say things, but it is hard to do them."
