The miller was at first struck dumb, but when he heard her speak so kindly, he took heart, and told her how he had formerly lived in wealth and happiness, but that now he was so poor that he did not know what to do. “Be easy,” answered the nix, “I will make thee richer and happier than thou hast ever been before, only thou must promise to give me the young thing which has just been born in thy house.”

“What else can that be,” thought the miller, “but a young puppy or kitten?” and he promised her what she desired. The nix descended into the water again, and he hurried back to his mill, consoled and in good spirits. He had not yet reached it, when the maidservant came out of the house, and cried to him to rejoice, for his wife had given birth to a little boy. The miller stood as if struck by lightning; he saw very well that the cunning nix had been aware of it, and had cheated him.

Hanging his head, he went up to his wife’s bedside and when she said, “Why dost thou not rejoice over the fine boy?” he told her what had befallen him, and what kind of a promise he had given to the nix.
