'Well, I'm no scholard. But I did hear Mr. Noah say once in a lecture--_he's_ a speaker, if you like--I heard him say it was like when you take a person's photo. The person is so many inches thick through and so many feet high and he's round and he's solid. But in the photo he's _flat_. Because everything's flat in photos. But all the same it's him right enough. You get him into the photo. Then all you've got to do is to get 'im out again into where everything's thick and tall and round and solid. And it's quite easy, I believe, once you know the trick.' 'Stop,' said Philip suddenly. 'I think my head's going to burst.' 'Ah!' said the carpenter kindly. 'I felt like that at first. Lie down and try to sleep it off a bit. Eddication does go to your head something crool. I've often noticed it.' And indeed Philip was quite glad to lie down among the long grass and be covered up with the carpenter's coat. He fell asleep at once. An hour later he woke again, looked at the wrinkled-apple face of Mr. Perrin and began to remember. 'I'm glad _you're_ here anyhow,' he said to the carpenter; 'it was horribly lonely. You don't know.' 'That's why I was sent to meet you,' said Mr. Perrin simply. 'But how did you know?' 'Mr. Noah sent for me early this morning. Bless you, he knows all about everything. Says he, "You go and meet 'im and tell 'im all you can. If he wants to be a Deliverer, let 'im," says Mr. Noah.' 'But how do you begin being a Deliverer?' Philip asked, sitting up and feeling suddenly very grand and manly, and very glad that Lucy was not there to interfere. 'There's lots of different ways,' said Mr. Perrin. 'Your particular way's simple. You just got to kill the dragon.' 'A _live_ dragon?' 'Live!' said Mr. Perrin. 'Why he's all over the place and as green as grass he is. Lively as a kitten. He's got a broken spear sticking out of his side, so some one must have had a try at baggin' him, some time or another.' 'Don't you think,' said Philip, a little overcome by this vivid picture, 'that perhaps I'd better look for Lucy first, and be a Deliverer afterwards?' 'If you're _afraid_,' said Mr. Perrin. 'I'm not,' said Philip doubtfully. 'You see,' said the carpenter, 'what you've got to consider is: are you going to be the hero of this 'ere adventure or ain't you? You can't 'ave it both ways. An' if you are, you may's well make up your mind, cause killing a dragon ain't the end of it, not by no means.' 'Do you mean there are more dragons?'
