“But it was a water-baby, and I heard it speak!” cried Ellie. “Ah, it is gone!” And she jumped down off the rock, to try and catch Tom before he slipped into the sea. [Picture: Ellie, the professor and Tom] Too late! and what was worse, as she sprang down, she slipped, and fell some six feet, with her head on a sharp rock, and lay quite still. The professor picked her up, and tried to waken her, and called to her, and cried over her, for he loved her very much: but she would not waken at all. So he took her up in his arms and carried her to her governess, and they all went home; and little Ellie was put to bed, and lay there quite still; only now and then she woke up and called out about the water-baby: but no one knew what she meant, and the professor did not tell, for he was ashamed to tell. And, after a week, one moonlight night, the fairies came flying in at the window and brought her such a pretty pair of wings that she could not help putting them on; and she flew with them out of the window, and over the land, and over the sea, and up through the clouds, and nobody heard or saw anything of her for a very long while. And this is why they say that no one has ever yet seen a water-baby. For my part, I believe that the naturalists get dozens of them when they are out dredging; but they say nothing about them, and throw them overboard again, for fear of spoiling their theories. But, you see the professor was found out, as every one is in due time. A very terrible old fairy found the professor out; she felt his bumps, and cast his nativity, and took the lunars of him carefully inside and out; and so she knew what he would do as well as if she had seen it in a print book, as they say in the dear old west country; and he did it; and so he was found out beforehand, as everybody always is; and the old fairy will find out the naturalists some day, and put them in the _Times_, and then on whose side will the laugh be? So the old fairy took him in hand very severely there and then. But she says she is always most severe with the best people, because there is most chance of curing them, and therefore they are the patients who pay her best; for she has to work on the same salary as the Emperor of China’s physicians (it is a pity that all do not), no cure, no pay.
