"Blessings on you as broad as your back, Harthover," says she--she didn't call him Sir John, but only Harthover, for that is the fashion in the North country--"and welcome into Vendale; but you're no hunting the fox this time of the year?" "I am hunting, and strange game too," said he. "Blessings on your heart, and what makes you look so sad the morn?" "I'm looking for a lost child, a chimney-sweep, that is run away." "Oh, Harthover, Harthover," says she, "ye were always a just man and a merciful; and ye'll no harm the poor lad if I give you tidings of him?" "Not I, not I, dame. I'm afraid we hunted him out of the house all on a miserable mistake, and the hound has brought him to the top of Lewthwaite Crag, and--" Whereat the old dame broke out crying, without letting him finish his story. "So he told me the truth after all, poor little dear! Ah, first thoughts are best, and a body's heart'll guide them right, if they will but hearken to it." And then she told Sir John all. "Bring the dog here, and lay him on," said Sir John, without another word, and he set his teeth very hard. And the dog opened at once; and went away at the back of the cottage, over the road, and over the meadow, and through a bit of alder copse; and there, upon an alder stump, they saw Tom's clothes lying. And then they knew as much about it all as there was any need to know. And Tom? Ah, now comes the most wonderful part of this wonderful story. Tom, when he woke, for of course he woke--children always wake after they have slept exactly as long as is good for them--found himself swimming about in the stream, being about four inches, or--that I may be accurate-- 3.87902 inches long, and having round the parotid region of his fauces a set of external gills (I hope you understand all the big words) just like those of a sucking eft, which he mistook for a lace frill, till he pulled at them, found he hurt himself, and made up his mind that they were part of himself, and best left alone. In fact, the fairies had turned him into a water baby. A water baby? You never heard of a water baby? Perhaps not. That is the very reason why this story was written. There are a great many things in the world which you never heard of; and a great many more which nobody ever heard of; and a great many things, too, which nobody will ever hear of. No water babies, indeed? Why, wise men of old said that everything on earth had its double in the water; and you may see that that is, if not quite true, still quite as true as most other theories which you are likely to hear for many a day. There are land babies--then why not water babies? ARE THERE NOT WATER RATS, WATER FLIES, WATER CRICKETS, WATER CRABS, WATER TORTOISES, WATER SCORPIONS, WATER TIGERS AND SO ON WITHOUT END? Am I in earnest? Oh dear no! Don't you know that this is a fairy tale, and all fun and pretense; and that you are not to believe one word of it, even if it is true?
