“But we haven‘t seen anything yet，” said Digory. “Now we’re here， we simply must have a look round.”
“I‘m sure there’s nothing at all interesting here.”
“There‘s not much point in finding a magic ring that lets you into other worlds if you’re afraid to look at them when you‘ve got there.”
“Who’s talking about being afraid？” said Polly， letting go of Digory‘s hand.
“I only thought you didn’t seem very keen on exploring this place.”
“I‘ll go anywhere you go.”
“We can get away the moment we want to，” said Digory. “Let’s take off our green rings and put them in our right. hand pockets. All we‘ve got to do is to remember that our yellow are in our left.hand pockets. You can keep your hand as near your pocket as you like， but don’t put it in or you‘ll touch your yellow and vanish.”
They did this and went quietly up to one of the big arched doorways which led into the inside of the building.
