But in the evening, when she stood by the tower window as usual, and listened to the nightingale, she had no longer any doubts as to what she should do. To be able to sing like the nightingale was more important than anything else, she felt. And besides, if she were going to be turned into a bird, the pearls would not be of much use to her in any case. She was pretty sure that nightingales never wore pearl necklaces.

The next day she slipped one of the pearls off her chain, and then she ran out of the castle and through the wood and down the hill, till she came to the dark cave.

The Wise man smiled when he saw her.

"Here is——" she began, and then she could say no more, because of the lump in her throat.

The Wise Man looked rather sorry for her, but he took the pearl without speaking. Then he gave her the feather he had promised her, and she went away again. As she climbed the hill and ran back through the wood to the castle, she tried to feel glad that she had the feather instead of the pearl.

For a long, long time the same thing happened every day. Every day Agatha slipped a pearl off her chain, and then ran out of the castle and through the wood and down the hill, till she came to the dark cave; and every day she brought home a little feather instead of her pearl.

The long loop of the chain grew shorter and shorter. The time came when it was not a long loop at all, but fitted closely round Agatha's neck as the other loops did. By-and-by the time came when the chain would only pass twice round her throat; then the time came when it would only go round her throat once; then it grew too short to reach round her throat at all, and she was obliged to turn it into a bracelet. Then it became too short for her wrist, and she made it into a ring. And all the time her store of feathers was growing larger and larger, till it seemed to her that there were enough to make at least ten nightingales; but this was because she did not know how many feathers a nightingale likes to have. When there were only two pearls left, the Wise Man said to her—

"When you bring me the last pearl you must bring me the feathers too; and after that you will be able to sing with a beautiful voice and to fly wherever you like."

So when Agatha left the gloomy old castle for the last time she was not able to run through the wood, because she was carrying a big bag of feathers as well as the pearl.

She was feeling very much excited when she gave the bag of feathers to the Wise Man.
