When she awoke the moon was shining, and although she was in the forest alone she was not afraid, for she did not think any one would harm a princess, so she rolled over on her soft bed, thinking she would go to sleep again, when something cold touched her cheek.

Princess Dido opened her eyes very wide then and sat up, and on a bush beside her she saw a very small gold key hanging by a thread which swung back and forth and half touched her face.

“I wonder what this cunning little key can fit,” said the Princess. “I do wish I knew! I am sure I should find something nice. I believe I will look about. I am not a bit sleepy, and the moon is as bright as day.”

Princess Dido hunted everywhere among the bushes and rocks, and nothing could she find, when, just as she had decided to go to sleep again, she saw something shining on a tree, and there was a tiny keyhole that the key just fitted.

She put the key in the lock and the tree opened like a door, and Princess Dido stepped inside and closed the door after her.

She walked along a road which seemed to be just behind the tree, but when she looked about she was not in the forest at all, but in a beautiful country filled with flowers and tall trees, and in the distance she saw a beautiful castle.

When Princess Dido came to the castle she saw fountains and more beautiful flowers growing around, and there were birds of all kinds singing in the trees.

“I suppose I must go to the door of the castle and let them know who I am,” thought the Princess. “A princess ought to do that, I know, but I would much rather stay in this beautiful garden and hear the birds sing and look at the flowers.”

When the Princess knocked at the door no one answered, and after waiting a short time the Princess opened the door and stepped inside. All was still and she sat down and waited.

“I expect everybody is at breakfast,” thought the Princess. “I wish I had something to eat. I didn’t have any supper, and I have not had my breakfast, either.
