‘No, I don’t remember any gall,’ replied Sam with some asperity; ‘and wot’s more, if that clutch ain’t ready pretty damn soon, you’ll be spoke to.’

‘The ‘Chief’ waved a reply, and with a snip of switches the motors started again. Then the engine clutches came home and the Diesels began to heave with a fizz bump, fizz bump, fizz, fizz, fizz, as the needles of the ammeters came back from discharging, past zero and on to charging.
