Gawaine took a cigarette. The Headmaster offered him a match, but he produced one of his own and began to puff away with a dexterity which quite amazed the principal. "Here you have learned the theories of life," continued the Headmaster, resuming the thread of his discourse, "but after all, life is not a matter of theories. Life is a matter of facts. It calls on the young and the old alike to face these facts, even though they are hard and sometimes unpleasant. Your problem, for example, is to slay dragons." "They say that those dragons down in the south wood are five hundred feet long," ventured Gawaine, timorously. "Stuff and nonsense!" said the Headmaster. "The curate saw one last week from the top of Arthur's Hill. The dragon was sunning himself down in the valley. The curate didn't have an opportunity to look at him very long because he felt it was his duty to hurry back to make a report to me. He said the monster, or shall I say, the big lizard?--wasn't an inch over two hundred feet. But the size has nothing at all to do with it. You'll find the big ones even easier than the little ones. They're far slower on their feet and less aggressive, I'm told. Besides, before you go I'm going to equip you in such fashion that you need have no fear of all the dragons in the world." "I'd like an enchanted cap," said Gawaine. "What's that?" answered the Headmaster, testily. "A cap to make me disappear," explained Gawaine. The Headmaster laughed indulgently. "You mustn't believe all those old wives' stories," he said. "There isn't any such thing. A cap to make you disappear, indeed! What would you do with it? You haven't even appeared yet. Why, my boy, you could walk from here to London, and nobody would so much as look at you. You're nobody. You couldn't be more invisible than that." Gawaine seemed dangerously close to a relapse into his old habit of whimpering. The Headmaster reassured him: "Don't worry; I'll give you something much better than an enchanted cap. I'm going to give you a magic word. All you have to do is to repeat this magic charm once and no dragon can possibly harm a hair of your head. You can cut off his head at your leisure." He took a heavy book from the shelf behind his desk and began to run through it. "Sometimes," he said, "the charm is a whole phrase or even a sentence. I might, for instance, give you 'To make the'--No, that might not do. I think a single word would be best for dragons." "A short word," suggested Gawaine. "It can't be too short or it wouldn't be potent. There isn't so much hurry as all that. Here's a splendid magic word: 'Rumplesnitz.' Do you think you can learn that?" Gawaine tried and in an hour or so he seemed to have the word well in hand. Again and again he interrupted the lesson to inquire, "And if I say 'Rumplesnitz' the dragon can't possibly hurt me?" And always the Headmaster replied, "If you only say 'Rumplesnitz,' you are perfectly safe."
