CHAPTER FIFTEEN THE WONDERS OF THE LAST SEA

VERY soon after they had left Ramandu’s country they began to feel that they had already sailed beyond the world．All was different．For one thing they all found that they were needing less sleep．One did not want to go to bed nor to eat much，nor even to talk except in low voices．Another thing was the light． There was too much of it．The sun when it came up each morning looked twice，if not three times，its usual size．And every morning(which gave Lucy the strangest feeling of all)the huge white birds，singing their song with human voices in a language no one knew，streamed overhead and vanished astern on their way to their breakfast at Aslan’s Table．A little later they came flying back and vanished into the east．

“How beautifully clear the water is ！”said Lucy to herself，as she leaned over the port side early in the afternoon of the second day．

And it was．The first thing that she noticed was a little black object，about the size of a shoe，travelling along at the same speed as the ship．For a moment she thought it was something floating on the surface．But then there came floating past a bit of stale bread which the cook had just thrown out of the galley．And the bit of bread looked as if it were going to collide with the black thing， but it didn’t．It passed above it，and Lucy now saw that the black thing could not be on the surface．Then the black thing suddenly got very much bigger and flicked back to normal size a moment later．

Now Lucy knew she had seen something just like that happen somewhere else—if only she could remember where．She held her hand to her head and screwed up her face and put out her tongue in the effort to remember．At last she did．Of course ！ It was like what you saw from a train on a bright sunny day．You saw the black shadow of your own coach running along the fields at the same pace as the train．Then you went into a cutting；and immediately the same shadow flicked close up to you and got big， racing along the grass of the cutting-bank．Then you came out of the cutting and—flick ！ —once more the black shadow had gone back to its normal size and was running along the fields．

“It’s our shadow ！—the shadow of the Dawn Treader，”said Lucy．“Our shadow running along on the bottom of the sea．That time when it got bigger it went over a hill．But in that case the water must be clearer than I thought ！ Good gracious，I must he seeing the bottom of the sea；fathoms and fathoms down．”

As soon as she had said this she realized that the great silvery expanse which she had been seeing(without noticing)for some time was really the sand on the sea-bed and that ail sorts of darker or brighter patches were not lights and shadows on the surface but real things on the bottom．At present，for instance，they were passing over a mass of soft purply green with a broad，winding strip of pale grey in the middle of it．But now that she knew it was on the bottom she saw it much better．She could see that bits of the dark stuff were much higher than other bits and were waving gently ．“Just like trees in a wind，”said Lucy．“And I do believe that’s what they are．It’s a submarine forest．”

They passed on above it and presently the pale streak was joined by another pale streak．“If I was down there，”thought Lucy，“that streak would be just like a road through the wood．And that place where it joins the other Would be a crossroads．Oh， I do wish I was．Hallo ！the forest is coming to an end．And I do believe the streak really was a road ！ I can still see it going on across the open sand．It’s a different colour．And it’s marked out with something at the edges—dotted lines．Perhaps they are stones． And now it’s getting wider．”

But it was not really getting wider，it was getting nearer．She realized this because of the way in which the shadow of the ship came rushing up towards her．And the road—she felt sure it was a road now—began to go in zigzags．Obviously it was climbing up a steep hill．And when she held her head sideways and looked back，what she saw was very like what you see when you look down a winding road from the top of a hill．She could even see the shafts of sunlight falling through the deep water onto the wooded valley—and，in the extreme distance，everything melting away into a dim greenness．But some places—the sunny ones，she thought—were ultramarine blue．

She could not，however，spend much time looking back； what was coming into view in the forward direction was too exciting．The road had apparently now reached the top of the hill and ran straight forward．Little specks were moving to and fro on it．And now something most wonderful，fortunately in full sunlight—or as full as it can be when it falls through fathoms of water—flashed into sight．It was knobbly and jagged and of a pearly，or perhaps an ivory，colour．She was so nearly straight above it that at first she could hardly make out what it was． But everything became plain when she noticed its shadow．The sunlight was falling across Lucy’s shoulders，so the shadow of the thing lay stretched out on the sand behind it．And by its shape she saw clearly that it was a shadow of towers and pinnacles，minarets and domes．
