He went three times around it, and each time he said:
"Open, door! open, door!
Let me come in."
When he had gone three times around, a door opened. In he went.
The door shut after him, and he was in the dark.
Soon he began to see a dim light.
It seemed to come from the walls.
He went down a long way, and at last he came to another door.
All at once it flew open, and he found himself in a great hall.
The walls were of gold and silver, and were hung with diamonds.
