'Oh dear!' said Leo's mother, 'there, I have run out of stamps again. And I don't like getting them from the servants. It is so apt to cause mistakes. It is really very stupid of me. Have you any, Marion?'

Marion was Leo's big sister. She was fifteen.

'I have one or two—yes, three,' Marion answered. 'Will that do, mamma?'

'It must do; oh yes, I think there are only three letters that really matter. I can't send for any so late. The servants are all busy; these letters can be put in the pillar-box just opposite. But I really must not let myself run out of stamps in this way.'

'Some days you have so many more letters than others. It must be difficult to know how many stamps you need,' said Marion, who thought mamma so perfect that she did not even like to hear her calling herself 'stupid' for running short of stamps.

'I wish we had a post-office in the house,' said Cynthia, the next sister. 'I did so want a postcard to send to Fletcher's to order my new piece of music, and when I was out I forgot to get any, though mamma said I might buy a whole packet. It's cheaper—for you get twelve for eightpence, and if you buy one at a time it's a penny each.'

'Or two for three-halfpence,' said Leo. 'That would make ninepence for twelve, not eightpence.'

'That's just like Leo,' said Cynthia; 'he's always counting about money and things like that. You're a regular little merchant, Leo.'
