'It's like the shadows talking, isn't it?' said Una. She had given up trying to read. Dan lay over the bows, trailing his hands in the current. They heard feet on the gravel-bar that runs half across the pool and saw Sir Richard Dalyngridge standing over them.

'Was yours a dangerous voyage?' he asked, smiling.

'She bumped a lot, sir,' said Dan. 'There's hardly any water this summer.'

'Ah, the brook was deeper and wider when my children played at Danish pirates. Are you pirate-folk?'

'Oh no. We gave up being pirates years ago,' explained Una. 'We're nearly always explorers now. Sailing round the world, you know.'

'Round?' said Sir Richard. He sat him in the comfortable crotch of an old ash-root on the bank. 'How can it be round?'

'Wasn't it in your books?' Dan suggested. He had been doing geography at his last lesson.

'I can neither write nor read,' he replied. 'Canst thou read, child?'

'Yes,' said Dan, 'barring the very long words.'

'Wonderful! Read to me, that I may hear for myself.'
