"You are just in time," said the witch. "After the sun comes up tomorrow, a whole year would have to go by before I could be of any help to you. J shall compound you a draught, and before sunrise you must swim to the shore with it, seat yourself on dry land, and drink the draught down. Then your tail will divide and shrink until it becomes what the people on earth call a pair of shapely legs. But it will hurt; it will feel as if a sharp sword slashed through you. Everyone who sees you will say that you are the most graceful human being they have ever laid eyes on, for you will keep your gliding movement and no dancer will be able to tread as lightly as you. But every step you take will feel as if you were treading upon knife blades so sharp that blood must flow. I am willing to help you, but are you willing to suffer all this?"
"Yes," the little mermaid said in a trembling voice, as she thought of the Prince and of gaining a human soul.
"Remember!" said the witch. "Once you have taken a human form, you can never be a mermaid again. You can never come back through the waters to your sisters, or to your father's palace. And if you do not win the love of the Prince so completely that for your sake he forgets his father and mother, cleaves to you with his every thought and his whole heart, and lets the priest join your hands in marriage, then you will win no immortal soul. If he marries someone else, your heart will break on the very next morning, and you will become foam of the sea."
"I shall take that risk," said the little mermaid, but she turned as pale as death.
"Also, you will have to pay me," said the witch, "and it is no trifling price that I'm asking. You have the sweetest voice of anyone down here at the bottom of the sea, and while I don't doubt that you would like to captivate the Prince with it, you must give this voice to me. I will take the very best thing that you have, in return for my sovereign draught. I must pour my own blood in it to make the drink as sharp as a two-edged sword."
"But if you take my voice," said the little mermaid, "what will be left to me?"
"Your lovely form," the witch told her, "your gliding movements, and your eloquent eyes. With these you can easily enchant a human heart. Well, have you lost your courage? Stick out your little tongue and I shall cut it off. I'll have my price, and you shall have the potent draught."
"Go ahead," said the little mermaid.
The witch hung her caldron over the flames, to brew the draught. "Cleanliness is a good thing," she said, as she tied her snakes in a knot and scoured out the pot with them. Then she pricked herself in the chest and let her black blood splash into the caldron. Steam swirled up from it, in such ghastly shapes that anyone would have been terrified by them. The witch constantly threw new ingredients into the caldron, and it started to boil with a sound like that
