But I do not choose to have any man alive tell me of it.’ ‘Oh no, no, no, ’ cried Jack. ‘I should never dream of doing such a thing.

Tace is the Latin for a candle. I quite understand - am amazed I did not smoke it before: what a deep old file you are. But I twig it now.’ ‘Do you, my dear? Bless you.’
