did i tell you before what a kindhearted boy edmund was? he sat down on the brass doorstep and waited till three o'clock. then he knocked and rang, and there was a rattling and puffing inside. the great door flew open, and edmund had only just time to hide behind it when out came an immense yellow dragon, who wriggled off down the brass cave like a long, rattling worm or perhaps more like a monstrous centipede.
