     One day a poor man was cutting a big piece of wood near a river. Suddenly his old axe fell into the

water. He felt very sad because he lost his only axe. Then all at once a beautiful fairy came out and asked

the man what the matter was.

     ''I  have lost my axe," he said. "It fell into the water when I was cutting the wood." The fairy showed

him a gold axe and asked, "Is this yours?" "No," said the man. The fairy then showed him a silver axe and

asked again, "Is this yours?" "No," again answered the man.  Then she showed him the old axe. "Yes, that
