' The little fellow shook with laughter. 'Indeed, it isn't
wrong. You've done something that Kings and Knights and Scholars in
old days would have given their crowns and spurs and books to find out.
If Merlin himself had helped you, you couldn't have managed better!
You've broken the Hills--you've broken the Hills! It hasn't happened in
a thousand years.'

'We--we didn't mean to,' said Una.

'Of course you didn't! That's just why you did it. Unluckily the Hills
are empty now, and all the People of the Hills are gone. I'm the only
one left. I'm Puck, the oldest Old Thing in England, very much at your
service if--if you care to have anything to do with me. If you don't,
of course you've only to say so, and I'll go.'

He looked at the children, and the children looked at him for quite

He brushed the crumbs carefully from his doublet and shook hands.

'We always said, Dan and I,' Una stammered, 'that if it ever happened
we'd know ex-actly what to do; but--but now it seems all different
somehow.'

'She means meeting a fairy,'said Dan. 'I never believed in 'em--not
after I was six, anyhow.'

'I did,' said Una. 'At least, I sort of half believed till we learned
"Farewell, Rewards". Do you know "Farewell, Rewards and Fairies"?'

'Do you mean this?' said Puck. He threw his big head back and began at
the second line:

'Good housewives now may say,
For now foul sluts in dairies

Than maids were wont to do,
Yet who of late for cleanliness
