Finding that none of the keys he first held would open the lock the lad had drawn out another handful; but these were no better than the others. One after another he tried all that he had, but not any would unlock the door. Having tried the last of all, the boy threw it down and sank upon the floor in despair.

"It is no good," he cried. "It is just as I feared. And yet I've been collecting those keys for the last seven months."

"Can't you unlock it?"

"No."

"Then what are you going to do?"

"I don't know. I didn't mind the desert or the dragon, but this was what I was afraid of all along."

"Mistress," said the gander, "Where is the key that the lady Fatima gave you? If what she said was true, it should unlock the door."

"Oh yes!" cried Ellen. "I forgot it."

With eager fingers she took the key from her pocket and pressed it into the lad's hand. "Try this," she said.
