Hardly a word was spoken on board all that day, till about dinner-time (no one wanted any dinner, the water was enough for them) Drinian said:
“I can't understand this. There is not a breath of wind. The sail hangs dead. The sea is as flat as a pond. And yet we drive on as fast as if there were a gale behind us.”
“I've been thinking that, too,” said Caspian. “We must be caught in some strong current.”
“H'm,” said Edmund. “That's not so nice if the world really has an edge and we're getting near it.”
“You mean,” said Caspian, “that we might be just – well, poured over it?”
“Yes, yes,” cried Reepicheep, clapping his paws together. “That's how I've always imagined it – the world like a great round table and the waters of all the oceans endlessly pouring over the edge. The ship will tip up – stand on her head – for one moment we shall see over the edge – and then, down, down, the rush, the speed – ”
“And what do you think will be waiting for us at the bottom, eh?” said Drinian.
“Aslan's country, perhaps,” said the Mouse, its eyes shining. “Or perhaps there isn't any bottom. Perhaps it goes down for ever and ever. But whatever it is, won't it be worth anything just to have looked for one moment beyond the edge of the world.”
“But look here,” said Eustace, “this is all rot. The world's round – I mean, round like a ball, not like a table.”
“Our world is,” said Edmund. “But is this?”
“Do you mean to say,” asked Caspian, “that you three come from a round world (round like a ball) and you've never told me! It's really too bad for you. Because we have fairy-tales in which there are round worlds and I always loved them. I never believed there were any real ones. But I've always wished there were and I've always longed to live in one. Oh, I'd give anything – I wonder why you can get into our world and we never get into yours? If only I had the chance! It must be exciting to live on a thing like a ball. Have you ever been to the parts where people walk about upside-down?”
Edmund shook his head. “And it isn't like that,” he added. “There's nothing particularly exciting about a round world when you're there.”
