Mamma smiled.

'Yes, that would be very nice, certainly,' she said. 'But it wouldn't be much good to you, Leo, if you gave your trouble and lent your money for nothing? You should make some profit, even if it were only a halfpenny on a dozen stamps.'

'Or a penny on twelve postcards,' said Leo consideringly. 'I might buy a whole packet and sell them in ones or twos. That would be very nice. But even without that, I would so like to have a post-office, mamma. It would really be a help to you.'

So it was settled. Mamma gave Leo five shillings out of his 'packet,' which was a private savings-bank she kept for him, and Leo, as happy as a king, set off to the chemist's shop round the corner, which was the nearest post-office in the neighbourhood, and laid out the whole five shillings in penny stamps, halfpenny stamps, a packet of postcards, another of newspaper wrappers, a few twopence-halfpenny stamps, and two or three foreign postcards, just in case mamma were writing to France, or Germany, as she sometimes did. The chemist did look rather astonished at such extensive purchases, but he was very civil and obliging; and as he was a nice man, Leo felt glad he had gone to him instead of to the big post-office a quarter of a mile off.

'For he must gain something on as much as five shillings,' thought Leo.

Then he came home and began to make his arrangements. He had to consult his sisters about them, but they were very kind and very much interested, and were quite pleased that the post-office should be in the schoolroom, which of course was as much their room as Leo's.

There was a little old-fashioned cupboard or bookcase in the schoolroom, in which, above the enclosed part which had glass doors, were two little drawers not used for anything in particular. On these drawers Leo had set his heart. 'They would be just the thing,' he thought. And luckily Marion and Cynthia thought the same. So the drawers were cleared of such contents as they had, and Leo set to work.
