Puck of Pook's Hill (Project Gutenberg): "Dan handed over his big one-bladed outdoor knife, and Puck began to carve out a piece of turf from the centre of the Ring.
'What's that for - Magic?' said Una, as he pressed up the square of chocolate loam that cut like so much cheese.
'One of my little magics,' he answered, and cut another. 'You see, I can't let you into the Hills because the People of the Hills have gone; but if you care to take seisin from me, I may be able to show you something out of the common here on Human Earth. You certainly deserve it.'
'What's taking seisin?' said Dan, cautiously.
'It's an old custom the people had when they bought and sold land. They used to cut out a clod and hand it over to the buyer, and you weren't lawfully seised of your land - it didn't really belong to you - till the other fellow had actually given you a piece of it -'like this.' He held out the turves. "
