"Father says," said Wag, who was sitting on a book, as usual--"Oh, what fun it is to be able to fly again!" And he darted straight and level and butted head first into the back of--Sprat, was it?--who was standing near the edge of the table. Sprat was merely propelled into the air a foot or two off, and remained standing, but, of course, turned round and told Wag what he thought of him. Wag returned contentedly to his book. "Father says," he resumed, "he hopes you'll come and see us now. He says you did all right, and he's very glad the stuff got spilt, because they'll take moons and moons to get as much of it together again. He says they meant to squirt some of it on you when they got near enough, and while you were trying to get it off they'd have got hold of----" He pointed to the box of jars; there was a shyness about mentioning it. "Your father's very kind," I said, "and I hope you'll thank him from me; but I don't quite see how I'm to get into your house." "Fancy you not knowing that!" said Wag. "I'll tell him you'll come." And he was out of the window. As usual, I had recourse to Slim. "Why, you did put some on your chest, didn't you?" was Slim's question. "Yes, but nothing came of it." "Well, I believe you can go pretty well anywhere with that, if you think you can." "Can I fly, then?" "No, I should say not; I mean, if you couldn't fly before, you can't now." "How do you fly? I don't see any wings." "No, we never have wings, and I'm rather glad we don't; the things that have them are always going wrong somehow. We just work it in the proper way with our backs, and there you are; like this." He made a slight movement of his shoulders, and was standing in the air an inch off the table. "You never tried that, I suppose?" he went on. "No," I said, "only in dreams," which evidently meant nothing to him. "Well now," I said, "do you tell me that if I went to Wag's house now, I could get inside it? Look at the size I am!" "It doesn't look as if you could," he agreed, "but my father said just the same as Wag's father about it." Here Wag shot on to my shoulder. "Are you coming?" "Yes, if I knew how." "Well, come and try, anyhow." "Very well, as you please; anything to oblige." I picked up a hat and went downstairs. All the rest followed, if you can call it following, when there was at least as much flying up steps and in and out of banisters as going down. When we were out on the path, Wag said with more seriousness than usual: "Now you do mean to come into our house, don't you?" "Certainly I do, if you wish me to." "Then that's all right. This way. There's Father."
