"Now, Harry and Laura, listen both of you--here is a grand opportunity to show everybody that we can be trusted to ourselves, without getting into any scrapes, so that if grandmamma is ever ill again and obliged to go away, she need not feel so sad and anxious as she did to-day. I mean to become nine times more attentive to my lessons than usual this morning, to show how trustworthy we are, and if you are wise, pray march straight up to the nursery yourselves. I have arranged a gown and cap of Mrs. Crabtree's on the large arm-chair, to look as like herself as possible, that you may be reminded how soon she will come back, and you must not behave like the mice when the cat is out. Good-bye! Say the alphabet backwards, and count your fingers for half an hour; but when Mrs. Crabtree appears again, pray do not jump out of the window for joy." Harry and Laura were proceeding directly towards the nursery, as Frank had recommended, when unluckily they observed, in passing the drawing-room door, that it was wide open; so Harry peeped in, and they began idly wandering round the tables and cabinets. Not ten minutes elapsed before they both commenced racing about as if they were mad, perfectly screaming with joy, and laughing so loudly at their own funny tricks that an old gentleman who lived next door very nearly sent in a message to ask what the joke was. Presently Harry and Laura ran up and down stairs till the housemaid was quite fatigued with running after them. They jumped upon the fine damask sofas in the drawing-room, stirred the fire till it was in a blaze, and rushed out on the balcony upsetting one or two geraniums and a myrtle. They spilt Lady Harriet's perfumes over their handkerchiefs,--they looked into all the beautiful books of pictures,--they tumbled many of the pretty Dresden china figures on the floor,--they wound up the little French clock till it was broken,--they made the musical work-box play its tunes, and set the Chinese mandarins a-nodding, till they very nearly nodded their heads off. In short, so much mischief has seldom been done in so short a time, till at last Harry, perfectly worn out with laughing and running, threw himself into a large arm-chair, and Laura, with her ringlets tumbling in frightful confusion over her face, and the beads of her coral necklace rolling on the floor, tossed herself into a sofa beside him. "Oh what fun!" cried Harry, in an ecstasy of delight. "I wish Frank had been here, and crowds of little boys and girls, to play with us all day! It would be a good joke, Laura, to write and ask all our little cousins and companions to drink tea here to-morrow evening! Their mammas could never guess we had not leave from grandmamma to invite everybody, so I daresay we might gather quite a large party! Oh how enchanting!"
