The Wager Landing

The device: the wager and the clock. Phileas Fogg says the whole world can be crossed in eighty days - and bets twenty thousand pounds that he can do it. A promise with a clock in it drives every page after. "I will bet twenty thousand pounds against any one who wishes, that I will make the tour of the world in eighty days or less. Do you accept?" A wager is a let's-pretend with rules: what must happen, by when, or else. Read the bet again. What exactly did Fogg promise - and what did he never promise?
