In front of them and the ground to fall steeply downhill. A minute later they came out under the open sky (the sun was still shining) and found themselves looking down on a fine sight. They were standing on the edge of a steep, narrow valley at the bottom of which ran – at least it would have been running if it hadn’t been frozen – a fairly large river. Just below them a dam had been built across this river, and when they saw it everyone suddenly remembered that of course beavers are always making dams and felt quite sure that Mr Beaver had made this one. They also noticed that he now had a sort of modest expression on his face – the sort of look people have when you are visiting a garden they’ve made or reading a story they’ve written. So it was only common politeness when Susan said, “What a lovely dam!” And MR Beaver didn’t say, “Hush” this time but, “Merely a trifle! Merely a trifle! And it isn’t really finished!” Above the dam there was what ought to have been a deep pool but was now, of course, a level floor of down, was more ice, but instead of being smooth this was all frozen into the foamy and wavy shapes in which the water had been rushing along at the very moment when the frost came. And where the water had been trickling over and spurting through the dam there was now a glittering wall of icicles, as if the side of the dam had been covered all over with flowers and wreaths and festoons of the purest sugar. And out in the middle, and partly on top of the fam was a funny little house shaped rather like an enormous beehive, and from a hole in the roof smoke was going up, so that when you saw it (especially if you were hungry) you at once thought of cooking and became hungrier than you were before. That was what the others chiefly noticed, but the river there was another small river which came down another small valley to join it. And looking up that valley, Edmund could see two small hills, and he was almost sure they were two hills which the White Witch had pointed out to him when he parted from her at the lamp-post that other day. And then between them, he thought, must be her palace, only a mile off or less. And he thought about Turkish Delight and about being King (“And I wonder how Peter will like that?” he asked himself) and horrible ideas came into his head. “Here we are,” said Mr Beaver, “and it looks as if Mrs Beaver is expecting us. I’ll lead the way. But be careful and don’t slip.”
