'It's the warm weather. They need something bracing. I'll give them a dose of iron mixture to-morrow,' said mamma. 'I've taken enough now to make a cooking-stove,' groaned Kitty, who hated being dosed. 'If you'd let me go swimming every night I'd be all right,' added Harry. 'Not another word on that point. I will _not_ let you do it, for you will get drowned as sure as you try,' said mamma, who was so timid she had panics the minute her boy was out of sight. 'Aunt Betsey let her boys go, and they never came to grief,' began Harry. 'Aunt Betsey's ideas and mine differ. Children are not brought up now as they were in her day,' answered mamma with a superior air. 'I just wish they were. Jolly good times _her_ boys had.' 'Yes, and girls too, playing anything they liked, and not rigged up and plagued with company,' cried Kitty, with sudden interest. 'What do you mean by that?' asked papa good-naturedly; for somehow his youth returned to him for a minute, and seemed very pleasant. The children could not explain very well, but Harry said slowly,-- 'If you were to be in our places for a day you'd see what we mean.' 'Wouldn't it be worth your while to try the experiment?' said Aunt Betsey, with a smile. Papa and mamma laughed at the idea, but looked sober when aunty added,-- 'Why not put yourselves in their places for a day and see how you like it? I think you would understand the case better than any one could describe it, and perhaps do both yourselves and the children a lasting service.' 'Upon my word, that's a droll idea! What do you say to it, mamma?' and papa looked much amused. 'I am willing to try it if you are, just for the fun of the thing, but I don't think it will do any good;' and mamma shook her head as if Aunt Betsey's plan was a wild one. The children sat quiet, speechless with surprise at this singular proposal, but as its full richness dawned upon them, they skipped in their chairs and clapped their hands delightedly. 'How do you propose to carry out this new educational frolic?' asked papa, beginning to feel some curiosity as to the part he was to play. 'Merely let the children do as they like for one day and have full power over you. Let them plan your duties and pleasures, order your food, fix your hours, and punish or reward you as they think proper. You must promise entire obedience, and keep the agreement till night.' 'Good! good! Oh, won't it be fun!' cried Harry and Kitty, applauding enthusiastically; while papa and mamma looked rather sober as the plan was developed before them. 'To-morrow is a holiday for us all, and we might celebrate it by this funny experiment. It will amuse us and do no harm, at any rate,' added aunty, quite in love with her new scheme.
