  A bright idea came into Alice's head.  `Is that the reason so
many tea-things are put out here?' she asked.

  `Yes, that's it,' said the Hatter with a sigh:  `it's always
tea-time, and we've no time to wash the things between whiles.'

  `Then you keep moving round, I suppose?' said Alice.

  `Exactly so,' said the Hatter:  `as the things get used up.'
