They came and stood together at the edge， looking down into the smooth water. It was full of the reflection of the green， leafy branches； they made it look very deep.
“We haven’t any bathing things，” said Polly.
“We shan‘t need them， silly，” said Digory. “We’re going in with our clothes on. Don‘t you remember it didn’t wet us on the way up？”
“Can you swim？”
“A bit. Can you？” “Well.not much.”
“I don‘t think we shall need to swim，” said Digory. “We want to go down， don’t we？”
Neither of them much liked the idea of jumping into that pool， but neither said so to the other. They took hands and said “One.Two.Three.Go” and jumped. There was a great splash and of course they closed their eyes. But when they opened them again they found they were still standing， hand in hand， in the green wood， and hardly up to their ankles in water. The pool was apparently only a couple of inches deep. They splashed back on to the dry ground.
“What on earth‘s gone wrong？” said Polly in a frightened voice； but not quite so frightened as you might expect， because it is hard to feel really frightened in that wood. The place is too peaceful.
