Think of a girl thus burdened working through a problem in mathematics, or arranging, in her mind, an analysis of it, which will be called for in five minutes; or, of her thinking over, so as to give clearly, with its heads and deductions, an abstract of a chapter in some branch of science! She will say, perhaps, that "one gets used to it and thinks nothing about it," and she thinks, no doubt, that what she says is quite true. But go to her room in the evening after the world is shut out, and you will, in all probability, find her with her wrapper on and her "braids" and "switches" off, and she will tell you, without thinking, what is nearer the truth--that you must excuse her, but she has a "hard lesson to get, and she can study so much better in this way, when she feels perfectly comfortable." A straw will tell which way the wind blows, and straws of hair-pins, during months of pain and feebleness, may, in after life, tell which way the wind has blown. Just in face of some of these hindrances, in the way of the higher education of our girls, I place some reports from schools and colleges which I have received. The following is from a teacher of high reputation, Superintendent of Public Schools in one of our large cities, a gentleman who has studied the science of teaching as few have done, and added to the usual attainments of a college graduate, studies which would have given him a right to practise as a physician. He has now been engaged in his profession, without a term's remission, for thirty years: "It is not hard study that breaks down the health of our girls, but the circumstances under which they study, the demands of society and its thousand social follies, with all their excitements. It is the foolish ambition of parents to have their daughters accomplished before they are out of their teens, often allowing them to carry on five or six branches at a time instead of two or three. These, and some other like causes, as I think, do more towards breaking down the health of girls at school, than much study. The ability on the part of the girls to master the several branches, is fully equal to that of the boys, and when an amount of study is reached that is injurious to girls, we have gone as far as is profitable for boys. Boys also break down in study, from some of the evils of society. As to co-education of the sexes, my experience, observation, and reading, all convince me that it is the best way. If there are incidental evils in such a course, they are only incidental, and I can find those of equal, or, I think, of greater magnitude in separate schools."
