Read the excerpt from Through the Looking Glass, by Lewis Carroll. "But oh!” thought Alice, suddenly jumping up, "if I don't make haste I shall have to go back through the Looking-glass, before I've seen what the rest of the house is like! Let's have a look at the garden first!” She was out of the room in a moment, and ran down stairs—or, at least, it wasn't exactly running, but a new invention of hers for getting down stairs quickly and easily, as Alice said to herself. She just kept the tips of her fingers on the hand-rail, and floated gently down without even touching the stairs with her feet; then she floated on through the hall, and would have gone straight out at the door in the same way, if she hadn't caught hold of the door-post. She was getting a little giddy with so much floating in the air, and was rather glad to find herself walking again in the natural way.
