PRINCESS HIDDEN UNDERGROUND 319
And immediately the king changed all the maidens into ducks, and he drove them before the young man, and said: ' Now show me which is my daughter.'
Then the princess, according to their understanding, began to clean her wings with her bill, and the lad said : ' She who cleans her wings is the princess.'
Now the king could do nothing more but give her to the young man to wife, and they lived together in great joy and happiness.
