“I see terribly big mountains, Aslan,” said Digory. “I see this river coming down cliffs in a waterfall. And beyond the cliff there are high green hills with forests. And beyond those there are higher ranges that look almost black. And then, far away, there are big snowy mountains all heaped up together.like pictures of the Alps. And behind those there’s nothing but the sky.”
“You see well,” said the Lion. “Now the land of Narnia ends where the waterfall comes down, and once you have reached the top of the cliffs you will be out of Narnia and into the Western Wild. You must journey through those mountains till you find a green valley with a blue lake in it, walled round by mountains of ice. At the end of the lake there is a steep, green hill. On the top of that hill there is a garden. In the centre of that garden is a tree. Pluck an apple from that tree and bring it back to me.”
“Yes, sir,” said Digory again. He hadn‘t the least idea of how he was to climb the cliff and find his way among all the mountains, but he didn’t like to say that for fear it would sound like making excuses. But he did say, “I hope, Aslan, you‘re not in a hurry. I shan’t be able to get there and back very quickly.”
