When they were about to set out, the water-cat said to them, “You do well to run away. You would not be happy here. But do not think my mistress will allow you to escape if she can help it. When she comes home and finds you gone, she will at once set out in pursuit of you. She can go very much faster than you, and she will certainly catch you unless you take with you her comb, her brush, and her mirror. These are magic things. Each time you find she is about to catch you, throw one or other of these things over your shoulder. By this means, and by this means only, can you hope to escape.”
The children thanked the little cat, and did as it advised them. They took the water-sprite’s brush and comb and mirror, and carried them off with them, and ran as fast as they could along the road that led to the upper world.
Soon after they had left, the water-sprite came home. When she found them gone she only stopped long enough to scold the cat, and then she put on her shoes of swiftness and started after them.
Presently the children looked behind them and saw her coming. She came so fast on her shoes of swiftness, that it seemed as though they could not possibly escape her.
However, the children remembered what the water-cat had told them. They threw the comb behind them, and at once it spread and grew into a wall of spikes, tremendously stiff and high. It took the water-sprite a long time to climb over this wall, and the children were well on their way before they heard her behind them again.
Then the little girl threw the brush over her shoulder. At once the brush became a great thick forest, through which the water-sprite could hardly find her way.
But she got through it at last, and then it did not take her long to be at their heels again.
“And now we have only one more thing left,” said the brother, and he threw the mirror behind him.
At once the mirror became a hill of glass so steep and smooth that no one could possibly climb it. The sprite tried to run up it, but no sooner had she gone a step or so than she slipped back again. At last, with a shriek of rage, she turned and fled back to her castle, and that was the last of her.
But the children went on their way, and the road led them straight to the upper world and the door of their home. After that they were always careful to keep away from the edge of the water-sprite’s well.
