It is as hard to explain how this sunlit land was different from the old Narnia as it would be to tell you how the fruits of that country taste. Perhaps you will get some idea of it if you think like this. You may have been in a room in which there was a window that looked out on a lovely bay of the sea or a green valley that wound away among mountains. And in the wall of that room opposite to the window there may have been a lookingglass. And as you turned away from the window you suddenly caught sight of that sea or that valley, all over again, in the looking glass. And the sea in the mirror, or the valley in the mirror, were in one sense just the same as the real ones: yet at the same time they were somehow different - deeper, more wonderful, more like places in a story: in a story you have never heard but very much want to know. The difference between the old Narnia and the new Narnia was like that. The new one was a deeper country: every rock and flower and blade of grass looked as if it meant more. I can't describe it any better than that: if ever you get there you will know what I mean.

It was the Unicorn who summed up what everyone was feeling. He stamped his right fore-hoof on the ground and neighed, and then cried:

"I have come home at last! This is my real country! I belong here. This is the land I have been looking for all my life, though I never knew it till now. The reason why we loved the old Narnia is that it sometimes looked a little like this. Bree-hee-hee! Come further up, come further in!"

He shook his mane and sprang forward into a great gallop - a Unicorn's gallop, which, in our world, would have carried him out of sight in a few moments. But now a most strange thing happened. Everyone else began to run, and they found, to their astonishment, that they could keep up with him: not only the Dogs and the humans but even fat little Puzzle and short-legged Poggin the Dwarf. The air flew in their faces as if they were driving fast in a car without a windscreen. The country flew past as if they were seeing it from the windows of an express train. Faster and faster they raced, but no one got hot or tired or out of breath.

CHAPTER SIXTEEN

FAREWELL TO SHADOWLANDS

IF one could run without getting tired, I don't think one would often want to do anything else. But there might be special reasons for stopping, and it was a special reason which made Eustace presently shout:

"I say! Steady! Look what we're coming to!"

And well he might. For now they saw before them Caldron Pool and beyond the Pool the high unclimbable cliffs and, pouring down the cliffs, thousands of tons of water every second, flashing like diamonds in some places and dark, glassy green in others, the Great Waterfall; and already the thunder of it was in their ears.

"Don't stop! Further up and further in," called Farsight, tilting his flight a little upwards.

"It's all very well for him," said Eustace, but Jewel also cried out:

"Don't stop. Further up and further in! Take it in your stride."

His voice could only just be heard above the roar of the water but next moment everyone saw that he had plunged into the Pool. And helter-skelter behind him, with splash after splash, all the others did the same. The water was not biting cold as all of them (and especially Puzzle) expected, but of a delicious foamy coolness. They all found they were swimming straight for the Waterfall itself.

"This is absolutely crazy," said Eustace to Edmund.

"I know. And yet - " said Edmund.

"Isn't it wonderful?" said Lucy. "Have you noticed one can't feel afraid, even if one wants to? Try it."

"By Jove, neither one can," said Eustace after he had tried.

Jewel reached the foot of the Waterfall first, but Tirian was only just behind him. Jill was last, so she could see the whole thing better than the others. She saw something white moving steadily up the face of the Waterfall. That white thing was the Unicorn. You couldn't tell whether he was swimming or climbing, but he moved on, higher and higher. The point of his horn divided the water just above his head, and it cascaded out in two rainbow-coloured streams all round his shoulders. Just behind him came King Tirian. He moved his legs and arms as if he were swimming but he moved straight upwards: as if one could swim up the wall of a house.

What looked funniest was the Dogs. During the gallop they had not been at all out of breath, but now, as they swarmed and wriggled upwards, there was plenty of spluttering and sneezing among them; that was because they would keep on barking, and every time they barked they got their mouths and noses full of water. But before Jill had time to notice all these things fully, she was going up the Waterfall herself. It was the sort of thing that would have been quite impossible in our world. Even if you hadn't been drowned, you would have been smashed to pieces by the terrible weight of water against the countless jags of rock. But in that world you could do it. You went on, up and up, with all kinds of reflected lights flashing at you from the water and all manner of coloured stones flashing through it, till it seemed as if you were climbing up light itself - and always higher and higher till the sense of height would have terrified you if you could be terrified, but later it was only gloriously exciting. And then at last one came to the lovely, smooth green curve in which the water poured over the top and found that one was out on the level river above the Waterfall. The current was racing away behind you, but you were such a wonderful swimmer that you could make headway against it. Soon they were all on the bank, dripping buthappy.

A long valley opened ahead and great snow-mountains, now much nearer, stood up against the sky.

"Further up and further in," cried Jewel and instantly they were off again.

They were out of Narnia now and up into the Western Wild which neither Tirian nor Peter nor even the Eagle had ever seen before. But the Lord Digory and the Lady Polly had. "Do you remember? Do you remember?" they said - and said it in steady voices too, without panting, though the whole party was now running faster than an arrow flies.

"What, Lord?" said Tirian. "Is it then true, as stories tell, that you two journeyed here on the very day the world was made?"

"Yes," said Digory, "and it seems to me as if it were only yesterday."

"And on a flying horse?" asked Tirian. "Is that part true?"

"Certainly," said Digory. But the Dogs barked, "Faster, faster!"

So they ran faster and faster till it was more like flying than running, and even the Eagle overhead was going no faster than they. And they went through winding valley after winding valley and up the steep sides of hills and, faster than ever, down the other side, following the river and sometimes crossing it and skimming across mountainlakes as if they were living speed-boats, till at last at the far end of one long lake which looked as blue as a turquoise, they saw a smooth green hill. Its sides were as steep as the sides of a pyramid and round the very top of it ran a green wall: but above the wall rose the branches of trees whose leaves looked like silver and their fruit like gold.

"Further up and further in!" roared the Unicorn, and no one held back. They charged straight at the foot of the hill and then found themselves running up it almost as water from a broken wave runs up a rock out at the point of some bay. Though the slope was nearly as steep as the roof of a house and the grass was smooth as a bowling green, no one slipped. Only when they had reached the very top did they slow up; that was because they found themselves facing great golden gates. And for a moment none of them was bold enough to try if the gates would open. They all felt just as they had felt about the fruit "Dare we? Is it right? Can it be meant for us?"

But while they were standing thus a great horn, wonderfully loud and sweet, blew from somewhere inside that walled garden and the gates swung open.

Tirian stood holding his breath and wondering who would come out. And what came was the last thing he had expected: a little, sleek, bright-eyed Talking Mouse with a red feather stuck in a circlet on its head and its left paw resting on a long sword. It bowed, a most beautiful bow, and said in its shrill voice:

"Welcome, in the Lion's name. Come further up and further in."

Then Tirian saw King Peter and King Edmund and Queen Lucy rush forward to kneel down and greet the Mouse and they all cried out "Reepicheep!" And Tirian breathed fast with the sheer wonder of it, for now he knew that he was looking at one of the great heroes of Narnia, Reepicheep the Mouse who had fought at the great Battle of Beruna and afterwards sailed to the World's end with King Caspian the Seafarer. But before he had had much time to think of this he felt two strong arms thrown about him and felt a bearded kiss on his cheeks and heard a well remembered voice saying:
