“Yes， I’ve been wondering about that. But it was a what. do.you.call.it， a peninsula. Jolly nearly an island. Couldn‘t it have been made an island since our time？ Somebody has dug a channel.”
“But half a moment！” said Edmund. “You keep on saying since our time. But it’s only a year ago since we came back from Narnia. And you want to make out that in one year castles have fallen down， and great forests have grown up，and little trees we saw planted ourselves have turned into a big old orchard， and goodness knows what else. It‘s all impossible.”
“There’s one thing，” said Lucy. “If this is Cair Paravel there ought to be a door at this end of the dais. In fact we ought to be sitting with our backs against it at this moment. You know.the door that led down to the treasure chamber.”
“I suppose there isn‘t a door，” said Peter， getting up. The wall behind them was a mass of ivy.
“We can soon find out，” said Edmund， taking up one of the sticks that they had laid ready for putting on the fire. He began beating the ivied wall. Tap.tap went the stick against the stone， and again， tap.tap； and then， all at once， boomboom， with a quite different sound， a hollow， wooden sound.
“Great Scott！” said Edmund.
