Quote by C.S. Lewis

“They found a wide gateway open and passed through it into a paved courtyard. And it was here that they had their first indication that there was something odd about this island. In the middle of the courtyard stood a pump, and beneath the pump a bucket. There was nothing odd about that. But the pump handle was moving up and down, though there seemed to be no one moving it. “There’s some magic at work here,” said Caspian. “Machinery!” said Eustace. “I do believe we’ve come to a civilized country at last.” At that moment Lucy, hot and breathless, rushed into the courtyard behind them. In a low voice she tried to make them understand what she had overheard. And when they had partly understood it even the bravest of them did not look very happy. “Invisible enemies,” muttered Caspian. “And cutting us off from the boat. This is an ugly furrow to plow.” “You’ve no idea what of creatures they are, Lu?” asked Edmund. “How can I, Ed, when I couldn’t see them?” “Did they sound like humans from their footsteps?” “I didn’t hear any noise of feet--only voices and this frightful thudding and thumping--like a mallet.” “I wonder,” said Reepicheep, “do they become visible when you drive a sword into them?” “It looks as if we shall find out,” said Caspian. “But let’s get out of this gateway. There’s one of these gentry at that pump listening to all we say.” They came out and went back on to the path where the trees might possibly make them less conspicuous. “Not that it’s any good ,” said Eustace, “trying to hide from people you can’t see. They may be all round us.”
