"It may be objected that such things cannot be taught by books. Why not? Why may not the structure of the human body, and the laws of health deduced therefrom, be as well taught as the laws of natural philosophy? Why are not the application of these laws to the management of infants and young children as important to a woman as the application of the rules of arithmetic to the extraction of the cube root? Why may not the properties of the atmosphere be explained, in reference to the proper ventilation of rooms, or exercise in the open air, as properly as to the burning of steel or sodium? Why is not the human skeleton as curious and interesting as the air-pump; and the action of the brain, as the action of a steam-engine? Why may not the healthiness of different kinds of food and drink, the proper modes of cooking, and the rules in reference to the modes and times of taking them, be discussed as properly as rules of grammar, or facts in history? Are not the principles that should regulate clothing, the rules of cleanliness, the advantages of early rising and domestic exercise, as readily communicated as the principles of mineralogy, or rules of syntax? Are not the rules of Jesus Christ, applied to refine _domestic manners_ and preserve a _good temper_, as important as the abstract principles of ethics, as taught by Paley, Wayland, or Jouffroy? May not the advantages of neatness, system, and order, be as well illustrated in showing how they contribute to the happiness of a family, as by showing how they add beauty to a copy-book, or a portfolio of drawings? Would not a teacher be as well employed in teaching the rules of economy, in regard to time and expenses, or in regard to dispensing charity, as in teaching double, or single entry in bookkeeping? Are not the principles that should guide in constructing a house, and in warming and ventilating it properly, as important to young girls as the principles of the Athenian Commonwealth, or the rules of Roman tactics? Is it not as important that children should be taught the dangers to the mental faculties, when over-excited on the one hand, or left unoccupied on the other, as to teach them the conflicting theories of political economy, or the speculations of metaphysicians? For ourselves, we have always found children, especially girls, peculiarly ready to listen to what they saw would prepare them for future duties. The truth, that education should be _a preparation for actual, real life_, has the greatest force with children. The constantly-recurring inquiry, 'What will be _the use_ of this study?' is always satisfied by showing, that it will prepare for any duty, relation, or office which, in the natural course of things, will be likely to come. "We think this book extremely well suited to be used as a text-book in schools for young ladies, and many chapters are well adapted for a reading book for children of both sexes."
