Ah, but you did think of it, laughed the Hat. You wondered, you did, when you were told there was a thousand-year-old library, whether your most entertaining route to fame might be to burn the library and see what everyone says! You are not the first to wonder, nor are you the first with the courage to try such a stunt, and I doubt you shall be the first to succeed. The Hat seemed to be teasing him, as if he were a child who'd suggested it was a good idea to put the fire out with butterbeer, to save water. But you should be glad; you would regret, I think, the lost knowledge.
