But after a while Tom began to understand a little. For, as the vapours came up out of the hole, the bogy smelt them with his nostrils, and combed them and sorted them with his combs; and then, when they steamed up through them against his wings, they were changed into showers and streams of metal. From one wing fell gold-dust, and from another silver, and from another copper, and from another tin, and from another lead, and so on, and sank into the soft mud, into veins and cracks, and hardened there. Whereby it comes to pass that the rocks are full of metal. But, all of a sudden, somebody shut off the steam below, and the hole was left empty in an instant: and then down rushed the water into the hole, in such a whirlpool that the bogy spun round and round as fast as a teetotum. But that was all in his day's work, like a fair fall with the hounds; so all he did was to say to Tom-- "Now is your time, youngster, to get down, if you are in earnest, which I don't believe." "You'll soon see," said Tom; and away he went, as bold as Baron Munchausen, and shot down the rushing cataract like a salmon at Ballisodare. And, when he got to the bottom, he swam till he was washed on shore safe upon the Other-end-of-Nowhere; and he found it, to his surprise, as most other people do, much more like This-End-of-Somewhere than he had been in the habit of expecting. And first he went through Waste-paper-land, where all the stupid books lie in heaps, up hill and down dale, like leaves in a winter wood; and there he saw people digging and grubbing among them, to make worse books out of bad ones, and thrashing chaff to save the dust of it; and a very good trade they drove thereby, especially among children. Then he went by the sea of slops, to the mountain of messes, and the territory of tuck, where the ground was very sticky, for it was all made of bad toffee (not Everton toffee, of course), and full of deep cracks and holes choked with wind-fallen fruit, and green gooseberries, and sloes, and crabs, and whinberries, and hips and haws, and all the nasty things which little children will eat, if they can get them. But the fairies hide them out of the way in that country as fast as they can, and very hard work they have, and of very little use it is. For as fast as they hide away the old trash, foolish and wicked people make fresh trash full of lime and poisonous paints, and actually go and steal receipts out of old Madame Science's big book to invent poisons for little children, and sell them at wakes and fairs and tuck-shops. Very well. Let them go on. Dr. Letheby and Dr. Hassall cannot catch them, though they are setting traps for them all day long. But the Fairy with the birch-rod will catch them all in time, and make them begin at one corner of their shops, and eat their way out at the other: by which time they will have got such stomach-aches as will cure them of poisoning little children.
