'The whole world! Oh, Paul, you forgot. Not so well as my grandmother.'

'Why, not so well as my grandmother, perhaps; but, Anne, I can tell you that you must not talk yourself, Anne, but you must listen to me quietly, or else you won't understand what I am going to tell you; for I can assure you that I don't think I quite understood it myself, Anne, the first time my grandmother told it to me, though I stood stock-still listening my best.'

Prepared by this speech to hear something very difficult to be understood, Anne looked very grave, and her brother explained to her that with a guinea she might buy two hundred and fifty-two times as many plums as she could get for a penny.

'Why, Paul, you know the fruit-woman said she would give us a dozen plums for a penny. Now, for this little guinea would she give us two hundred and fifty-two dozen?'

'If she has so many, and if we like to have so many, to be sure she will,' said Paul; 'but I think we should not like to have two hundred and fifty-two dozen of plums; we could not eat such a number.'

'But we could give some of them to my grandmother,' said Anne.

'But still there would be too many for her, and for us, too,' said Paul, 'and when we had eaten the plums there would be an end to all the pleasure. But now I'll tell you what I am thinking of, Anne, that we might buy something for my grandmother that would be very useful to her indeed with the guinea—something that would last a great while.'

"We might buy something very useful with the guinea."

'What, brother? What sort of thing?'
