Next comes all involved in the _cleansing_, _neatness_, and _order_ of houses filled with sofas, ottomans, curtains, pictures, musical instruments, and all the varied collection of beautiful and frail ornaments or curiosities so common. Every girl should be taught to know the right and the wrong way of protecting or cleansing every article, from the rich picture-frames and frescoes to the humblest crockery and stew-pan. And this would include much scientific knowledge as well as practical training. Next comes the selection of _healthful food_, the proper care of it, and the most economical and suitable modes of cooking. Here are demanded the first principles of physiology, animal chemistry, and domestic hygiene, with the practical applications. Thus instructed, the housekeeper will know the good or bad condition of meats, milk, bread, butter, and all groceries. And a class could be taken to a market or grocery for illustration, as easily as to a museum or the field for illustrations of mineralogy or botany. All this should be done before a young girl has the heavy responsibilities of housekeeper, wife, mother, and nurse. The art of cookery, in all its departments, has received more attention than any other domestic duty in former days; but at the present time no systematic mode is devised for training a young girl to superintend and instruct servants in this complicated duty, on which the health and comfort of a family so much depend. Next, in providing _family clothing_ and in the care of household stuffs, she will know how to do and to teach in the best manner plain sewing, hemming, darning, mending, and the use of a sewing-machine, thus cultivating ingenuity, dexterity, and common sense in judging the best way of doing things and deciding what is worth doing and what is not. She will exercise good taste and good judgment in dress for herself and family, in the selection of materials, in the adaptation of colors and fashion to age, shape, and employments, and in the avoidance of unhealthful and absurd fashions; and she will have such knowledge of domestic chemistry as is needed in the cleansing, dyeing, and preservation of household clothing and stuffs. Next comes all involved in the _care of health_. This again involves the first principles of animal and domestic chemistry, hydrostatics, pneumatics, caloric, light, electricity, and especially hygiene and therapeutics. A housekeeper instructed in these will have pure water, pure air, much sunlight, beds and clothes well cleansed, every arrangement for cleanliness and comfort, and all that tends to prevent disease or retard its first approaches. And her knowledge and skill she will transmit to the children and servants under her care, while the dumb animals of her establishment will share in the blessings secured by her scientific knowledge and trained skill.
