Nothing gave the youngest princess such pleasure as to hear about the world of human beings up above them. Her old grandmother had to tell her all she knew about ships and cities, and of people and animals. What seemed nicest of all to her was that up on land the flowers were fragrant, for those at the bottom of the sea had no scent. And she thought it was nice that the woods were green, and that the fish you saw among their branches could sing so loud and sweet that it was delightful to hear them. Her grandmother had to call the little birds "fish," or the princess would not have known what she was talking about, for she had never seen a bird.
