“Tubs and tortoiseshells！” exclaimed Trumpkin. “If we’ve got lost coming， what chance have we of finding our way back？ And if we‘re to go back to the Island and begin all over again.even supposing we could.we might as well give the whole thing up. Miraz will have finished with Caspian before we get there at that rate.”
“You think we ought to go on？” said Lucy.
“I’m not sure the High King is lost，” said Trumpkin. “What‘s to hinder this river being the Rush？”
“Because the Rush is not in a gorge，” said Peter， keepinghis temper with some difficulty.
“Your Majesty says is，” replied the Dwarf， “but oughtn’t you to say was？ You knew this country hundreds.it may be a thousand.years ago. Mayn‘t it have changed？ A landslide might have pulled off half the side of that hill， leaving bare rock， and there are your precipices beyond the gorge. Then the Rush might go on deepening its course year after year till you get the little precipices this side. Or there might have been an earthquake， or anything.”
“I never thought of that，” said Peter.
