That was what the others chiefly noticed， but Edmund noticed something else. A little lower down 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 the 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 a 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.”
The top of the dam was wide enough to walk on， though not （for humans） a very nice place to walk because it was covered with ice， and though the frozen pool was level with it on one side， there was a nasty drop to the lower river on the other. Along this route Mr Beaver led them in single file right out to the middle where they could look a long way up the river and a long way down it. And when they had reached the middle they were at the door of the house.
