The Phoenix and the Carpet 

It began with the day when it was almost the Fifth of November, and a doubt arose in some breast-Robert’s, I fancy-as to the quality of the fireworks laid in for the Guy Fawkes celebration.
‚They were jolly cheap, ‚ said whoever it was, and I think it was Robert, ‚and suppose they didn’t go off on the night? Those Prosser kids would have something to snigger about then.‘
‚The ones I got are all right, ‚ Jane said; ‚I know they are, because the man at the shop said they were worth thribble the money-‚
‚I’m sure thribble isn’t grammar, ‚ Anthea said.
‚Of course it isn’t, ‚ said Cyril; ‚one word can’t be grammar all by itself, so you needn’t be so jolly clever.‘
