They had not gone far before they came to a place where the ground became rough and there were rocks all about and little hills up and little hills down. At the bottom of one small valley Mr Tumnus turned suddenly aside as if he were going to walk straight into an unusually large rock, but at the last moment Lucy found he was leading her into the entrance of a cave. As soon as they were inside she found herself blinking in the light of a wood fire. Then Mr Tumnus stooped and took a flaming piece of wood out of the fire with a neat little pair of tongs, and lit a lamp. “Now we shan’t be long,” he said, and immediately put a kettle on.
