Anthea awoke at five. She had made herself wake, and I must tell you how it is done, even if it keeps you waiting for the story to go on. You get into bed at night, and lie down quite flat on your little back with your hands straight down by your sides. Then you say 'I must wake up at five' (or six, or seven, or eight, or nine, or whatever the time is that you want), and as you say it you push your chin down on to your chest and then bang your head back on the pillow. And you do this as many times as there are ones in the time you want to wake up at. (It is quite an easy sum.) Of course everything depends on your really wanting to get up at five (or six, or seven, or eight, or nine); if you don't really want to, it's all of no use. But if you do - well, try it and see. Of course in this, as in doing Latin proses or getting into mischief, practice makes perfect. Anthea was quite perfect. At the very moment when she opened her eyes she heard the black-and-gold clock down in the dining-room strike eleven. So she knew it was three minutes to five. The black-and-gold clock always struck wrong, but it was all right when you knew what it meant. It was like a person talking a foreign language. If you know the language it is just as easy to understand as English. And Anthea knew the clock language. She was very sleepy, but she jumped out of bed and put her face and hands into a basin of cold water. This is a fairy charm that prevents your wanting to get back into bed again. Then she dressed, and folded up her nightgown. She did not tumble it together by the sleeves, but folded it by the seams from the hem, and that will show you the kind of well-brought-up little girl she was. Then she took her shoes in her hand and crept softly down the stairs. She opened the dining-room window and climbed out. It would have been just as easy to go out by the door, but the window was more romantic, and less likely to be noticed by Martha. 'I will always get up at five,' she said to herself. 'It was quite too awfully pretty for anything.' Her heart was beating very fast, for she was carrying out a plan quite her own. She could not be sure that it was a good plan, but she was quite sure that it would not be any better if she were to tell the others about it. And she had a feeling that, right or wrong, she would rather go through with it alone. She put on her shoes under the iron veranda, on the red-and-yellow shining tiles, and then she ran straight to the sand-pit, and found the Psammead's place, and dug it out; it was very cross indeed. 'It's too bad,' it said, fluffing up its fur like pigeons do their feathers at Christmas time. 'The weather's arctic, and it's the middle of the night.' 'I'm so sorry,' said Anthea gently, and she took off her white pinafore and covered the Sand-fairy up with it, all but its head, its bat's ears, and its eyes that were like a snail's eyes.
