"Great king of the genii," cried the monster, "I will never again disobey you!"

At these words the fisherman took courage.

"What is this you are saying, great genius? Tell me your history and how you came to be shut up in that vase."

At this, the genius looked at the fisherman haughtily. "Speak to me more civilly," he said, "before I kill you."

"Alas! why should you kill me?" cried the fisherman. "I have just freed you; have you already forgotten that?"

"No," answered the genius; "but that will not prevent me from killing you; and I am only going to grant you one favour, and that is to choose the manner of your death."
