On this night that I have been telling you about, the Good People inside the rath were eating and drinking and dancing and making merry generally, as they do, you know, the most of the time. Perhaps you would like to have me tell you how the inside of the rath looked too. I will do the best I can. In the first place, the walls were all of silver and the floor was all of gold. Perhaps you don't know--no, I suppose you don't know--still you may happen to have heard of this before: the fairies know just where to find pretty much all the gold and silver and precious stones that there are in the world, if they happen to want them. They don't want much of them, of course--only just enough to make the walls and the roofs and the floors of their houses of, and to put all over their clothes and to make all their furniture and dishes of, and all their carriages and their boats, and a few other things--but they know where to find plenty of gold and silver, if they want it.
Now I think that I had better give you a little science. I believe that a book which children are to read, always ought to teach something, so I mean to teach you as much as I can. You must know, then, that gold is one of the heaviest things in the world. Now you know that the earth is always whirling round and round, so that the things that it is made of naturally get shaken up more or less. Besides that, it was once a good deal softer than it is now, so that the things that it is made of could move about more than they can now. And so the most of the gold, being, as I said, one of the heaviest things, got sifted down toward the bottom--that is, toward the centre of the earth. Only a little of it was left near the top, compared with what went to the bottom. It would not be at all surprising if the middle of the earth were a solid lump of gold, a thousand miles thick. But we poor men cannot dig down very deep into the earth. We can only scratch a little dirt off the top, and if we happen to grub up a few pounds of gold we think that we are rich, and the rest of the world thinks so too.
But the fairies laugh at us. They know how to go as deep into the earth as they choose, and so any fairy who chooses can give away gold all his life, and still have more of it in his dust-bin all the time than all the kings in the world have in their treasuries. And the other fairies don't call him rich.
