"What do you want?" he asked with a dreadful hiss and his breath was like steam and his long red tongue like a thin flame.

"O wise Serpent," said the mermaid, "do not frighten little Mary Louise. She is traveling through our country and means no harm."

"Then she may come into my kingdom," replied the great Serpent, and he glided swiftly away.

"Do not fear him," said the little mermaid. "I cannot go with you, but you will be perfectly safe," and she closed the door and swam away, leaving little Mary Louise all alone.

It was a strange country in which Mary Louise found herself as she followed the great Serpent who was now some distance ahead. Great trees and moss-covered rocks were on every side, and only by keeping to the narrow path was it possible to find a way through them.

By and by the Serpent stopped at a gate in a high stone wall, which swung open slowly as he tapped upon it.

"Now, let me tell you something," he said, leading Mary Louise to a seat beneath a beautiful tree in a large garden close by a stately castle.

While she rested on the marble bench the great Serpent coiled himself in a ring, his head raised about two feet above the ground. He had wonderful black eyes and as he looked at her she almost fancied there were tears in them.

"Once upon a time, not so very long ago," he began, "a young prince lived in this castle. But one day a wicked magician disguised as a poor beggar came to the kitchen door and asked for bread. Now it happened to be baking day, and the Royal Baker had just placed a thousand loaves of dough in the oven. He was tired and hot and said to the beggar in a cross voice: 'You must wait until evening.' This made the beggar man dreadfully angry, and the next minute he waved a crooked stick above his head and cried, 'Let the master of this castle and his household become snakes!' Instantly, a great change came over all who lived in the castle. The prince turned into a serpent and all the retainers became snakes."

As he finished speaking, the poor Snake gave a low cry and hid his head in the grass.
