'You call that nearly flat calm?'

'Course I do. There was nothing but a little bit of a lop.'

'A lop, d'you call it? And what the deuce are these craft like in a gale?'

'A bit lively, and most damnably wet,' said Wooten.

'Well, thank God I'm not a destroyer sailor!' exclaimed the civilian with a sigh of heartfelt relief. 'I think you fellows ought to get treble pay in bad weather.'

'So do I,' the naval officer agreed. 'But none of us get our deserts, thank Heaven!'
