But nothing of this kind could occur in an elementary day-school, where boys and girls, the rich and poor, should meet together. And to prevent any of the distinctions of vanity, they should be dressed alike, and all obliged to submit to the same discipline, or leave the school. The school-room ought to be surrounded by a large piece of ground, in which the children might be usefully exercised, for at this age they should not be confined to any sedentary employment for more than an hour at a time. But these relaxations might all be rendered a part of elementary education, for many things improve and amuse the senses, when introduced as a kind of show, to the principles of which dryly laid down, children would turn a deaf ear. For instance, botany, mechanics, and astronomy. Reading, writing, arithmetic, natural history, and some simple experiments in natural philosophy, might fill up the day; but these pursuits should never encroach on gymnastic plays in the open air. The elements of religion, history, the history of man, and politics, might also be taught by conversations, in the socratic form. After the age of nine, girls and boys, intended for domestic employments, or mechanical trades, ought to be removed to other schools, and receive instruction, in some measure appropriated to the destination of each individual, the two sexes being still together in the morning; but in the afternoon, the girls should attend a school, where plain work, mantua-making, millinery, etc. would be their employment. The young people of superior abilities, or fortune, might now be taught, in another school, the dead and living languages, the elements of science, and continue the study of history and politics, on a more extensive scale, which would not exclude polite literature. Girls and boys still together? I hear some readers ask: yes. And I should not fear any other consequence, than that some early attachment might take place; which, whilst it had the best effect on the moral character of the young people, might not perfectly agree with the views of the parents, for it will be a long time, I fear, before the world is so enlightened, that parents, only anxious to render their children virtuous, will let them choose companions for life themselves. Besides, this would be a sure way to promote early marriages, and from early marriages the most salutary physical and moral effects naturally flow. What a different character does a married citizen assume from the selfish coxcomb, who lives but for himself, and who is often afraid to marry lest he should not be able to live in a certain style. Great emergencies excepted, which would rarely occur in a society of which equality was the basis, a man could only be prepared to discharge the duties of public life, by the habitual practice of those inferior ones which form the man.
