At once a hand reached for it and a voice said: “For thirty long years you kept my treasure from me, and from a poor farmer-lad you have grown to be a wealthy man. Now you have enough, and I would like to have my fire-ball back again!”
Then the man knew what had happened, but the fox was gone.
Note: The thought underlying the story is the belief that the fox prepares the elixir of life out of his own breath, which he allows to rise to the moon. If a thief can rob him of the elixir he gains supernatural powers.
