"Mr. Tumnus! Whatever is the matter?" for the Faun's brown eyes had filled with tears and then the tears began trickling down his cheeks, and soon they were running off the end of his nose; and at last he covered his face with his hands and began to howl. (2.28)

The children were walking on hour after hour into what seemed a delicious dream. Long ago they had left the coats behind them. And by now they had even stopped saying to one another, "Look! There's a kingfisher!" or "I say, bluebells!" or "What was that lovely smell?" or "Just listen to that thrush!" They walked on in silence drinking it all in, passing through patches of warm sunlight into cool, green thickets and out again into wide mossy glades where tall elms raised the leafy roof far overhead, and then into dense masses of flowering currant and among hawthorn bushes where the sweet smell was almost overpowering. (12.1)

"It's an owl," said Peter. "This is going to be a wonderful place for birds. I shall go to bed now. I say, let's go and explore to-morrow. You might find anything in a place like this. Did you see those mountains as we came along? And the woods? There might be eagles. There might be stags. There'll be hawks."
"Badgers!" said Lucy.
"Snakes!" said Edmund.
"Foxes!" said Susan. (1.12-15)
