Mamma had an interesting book to read after the children had gone to bed, and their father had left her to write his letters. She read on for some time, and then she began to feel chilly, and looking up she saw that the fire was getting low. 'I'll go down to the study,' she thought. 'There's sure to be a good fire there.' As she went down-stairs it struck her that she would take a look into the schoolroom, and just notice if the 'post-office' drawers were shut, and all looking as usual. 'I might even,' she said to herself, 'count the stamps and compare my counting with Leo's to-morrow.' But it was dark in the schoolroom. The fire, however, was not quite out; she turned to look for a match or a spill to light one of the candles. Her back was turned to the door, but as she stood there she heard it creak a little as some one pushed it open and came into the room. And this some one, much to her surprise, marched straight up to the stamp drawer, not to the money one, as if well acquainted with the arrangements, and by the light which came in from the hall stood quietly helping himself to some stamps. And who do you think it was? Why no one in the world but Leo's father himself! Mamma all but burst out laughing, but she managed to stay quite still for a moment. Then she called out: 'What _are_ you doing in that drawer?' It was papa's turn to jump then! But he soon got over his start. 'What are you doing there all by yourself in the dark?' he said. 'And what should I be doing but taking a stamp or two, of course,' he went on, coolly. 'I've always forgotten to say what a good idea it is to have stamps and wrappers and things so handy here. I never knew you kept them here till a few nights ago, when I came in here to see if there was any coal, as my fire was nearly out, and the drawer was open.' 'Ah,' thought Mamma, 'Leo did say he had asked Cynthia to shut it the night he had a headache, and no doubt she forgot.' 'And,' papa went on, 'I was so glad to see where the stamps were, as I sometimes run short. Since then I've helped myself to whatever I wanted, two or three times.' [Illustration: The Culprit] 'So _you_ are the culprit,' Leo's mother exclaimed, laughing. And then she told the whole story. * * * * *
