“No, she would surely tell some one if we did,” said another. “Little human child, would you like us to teach you how to dance as we dance?” “Yes, yes,” cried Lucilla; and now they were sweeping down near the ground, and the fairies slid off the sail with Lucilla in their arms, and let her slide gently to earth. “Teach me to dance, I beg. I will never tell anybody.” “Ah, but that is what all mortals say,” whispered one who had not spoken yet, “no mortal can keep a secret. Never yet was one known who could be silent.” “Try me,” cried Lucilla again, “I will never tell. Indeed I will not,” and she looked entreatingly from one to another of the elves. “But if you did,” said they, “if you broke your promise to us when once you had made it, we should punish you severely.” “But I promise faithfully,” repeated Lucilla, “I will never tell any one.” “Well then, you may try,” they said. “Only remember, if you break your word to us, and tell any mortal who it was that taught you how to dance, you will never dance again, for your feet will become heavy as lead, and not only that, but some great misfortune will overtake whatever you love best in this world. But if you keep faith with us, then the windfairies will never forget you, but will come to your help in your direst hour of need.” “Teach me, teach me,” cried Lucilla; “indeed I will never, never tell, and I long to dance as you do.” “Come then,” they said, and some came behind her, and some went in front of her, and some took her arms and some her feet, and all at once Lucilla felt as if she were made of feather-down. She swayed up and down as lightly as they, and it seemed to her quite easy. Never had she been so happy, and she would gladly have danced for hours, but suddenly, just as the sun was beginning to show a red light in the sky, she heard her father’s horse galloping over the downs, and in an instant the windfairies had vanished. When the miller came up to her, he was angry with her for being out on the grass instead of warm in bed, but Lucilla dared not tell him what had kept her, or say that she had been playing with windfairies.
