Mr. Clapp says enthusiastically that we cannot imagine Rosalind or Portia or Cordelia or Juliet with neuralgia or headache. And I believe that Shakespeare's women have now taken the place of the more lackadaisical and sentimental heroines of the past in the minds of many girls.

Now that girls wish to be well, it is worth while to consider two questions. First, why is health so important? Unless the answer to this question is clear, how can any one be ready to sacrifice health to any higher duty? Girls do sacrifice it frequently even when they know what they are doing, but it is generally for a caprice, because they want to dance later or skate longer, or study unreasonably; or sometimes they cannot resist the temptation of food which is not convenient for them, or they are willing to indulge their nerves too much, or it is too much trouble not to take cold.

I wish every girl who knows that she does not live up to her light in this respect would say to herself once a day for a month, "I ought to be vigorously well if I want to do my part in the world, or to be in thoroughly good spirits." I wish she would think of the meaning of what she says, and then see if she does not do some things she is loth to do and avoid some pleasing temptations. I believe a month's application of this formula would give her a new insight into the value of health. I speak not only of health, but of vigorous health. We want to do our part in the world, and that part ought to be our utmost. Agassiz could work fifteen hours a day. Most of us could never do anything so magnificent as that, and the attempt to do it would probably end in our being unfitted to do any work at all. But suppose Agassiz had said, "Twelve hours is too much for most men to work, so I can afford to be careless of my surplus health as long as I have strength to work twelve hours." The world would not only have lost much in the matter of his discoveries, but the spirit of all his work would have been different. I do not mean that it was necessarily the best thing for Agassiz even to work fifteen hours a day on fishes. He might have given part of his time to music, or friends, or novels, because he saw that, on the whole, such recreation met the higher needs of life. But I mean that he was a man to whom a full life was possible for fifteen hours a day, and that he would have been wrong to be satisfied with less.

And now, second, how shall girls be thoroughly well? The laws of health are few and simple. They are so well understood by the parents of this generation that it may seem a waste of time to allude to them here. Yet I am writing for girls whose ideas are often vague.

One word in regard to the study of Physiology. It is a fine study. If a girl thoroughly understands how her body ought to work in health, how one organ acts with another, then, in case of any local disturbance, she will probably be capable of seeing how, if the general tone of the system is raised, the particular difficulty will disappear, and she will no longer follow blindly rules she has learned by rote. Yet people learn more by practice than by theory, and it is probable that the fascinating study of Physiology is of more use intellectually than physically to most school-girls. If they are allowed to dwell much on diseases of the body instead of on its normal action, the study may be a positive injury to them by leading to morbid conditions.

And now again, What are the essentials of health? Several things may be regarded as equally necessary, so that I cannot lay down rules in exactly the order of importance, yet it is purposely that I begin with

Breathe fresh air.

Food is important, but we can live hours without taking food, while we must have air every moment. Moreover, the oxygen of the air actually nourishes the body as food does, by forming a part of the blood.How shall we get fresh air? First, by spending all the time possible out of doors, both in summer and winter, in storm and sunshine. Every one acknowledges the advantage of exercise in the open air for its own sake; but in New England we have not yet learned how far it is possible to live in the open air. I was once at a country-house in Switzerland which illustrates this ideal. The breakfast-table was spread on a terrace shaded by plane-trees, outside the dining-room door. The table was then cleared and books and work brought out. The family devotions were conducted there. The students studied and wrote, the ladies sewed and knit, and the maids prepared the vegetables for dinner which was also eaten there. For six months in the year this was the ordinary course of life. It would not, to be sure, be possible in all climates, but oftener than we think.

Yet two thirds of our life must be passed in the house, and usually in closed rooms on account of the cold. Now two persons cannot sit an hour in one room before the air becomes vitiated. Most forms of ventilation prove inadequate. M. was a vigorous young lady who made it a rule to leave a window slightly open all the time she was at work, being careful not to sit in the draught. But where this is not convenient, it is a good plan to open a window wide every hour or two for a minute. I knew a girl who tried that plan, but gave it up because it seemed so ridiculous to jump up from her studies every little while for the purpose. Yet nothing is worse than to sit still at one occupation for several hours, and even the slight change of position would do one almost as much good as the fresh air.

It is indispensable to have the window open through the night in every sleeping-room. But here caution is needed, because when the body is quiet a draught is a serious injury. Strips of wood across the open part of the window will generally be sufficient protection. Some of you shiver at the idea of breathing out of door air in the winter. You are so cold! Do you know that the moment you begin to breathe it you begin to grow warm from the increased action of the blood? But

Do not take cold.

The results of colds are more serious than one likes to say. Consumption, pneumonia, catarrh, deafness are some of their names. And the whole tone of the system is lowered by them. But the over-careful people are precisely those who suffer most from colds, because here, as in so many other directions, the nerves have sway.

Now, most colds are taken in one of four ways: By sitting in a draught, by becoming thoroughly chilled, by wetting the feet, and by breathing raw air. But none of these things are necessarily injurious to a young girl in ordinary health—provided she at once does what she can to counteract their effects. Move out of the draught, warm the body as thoroughly as it was chilled, dry the feet before sitting down, and cover the mouth with a veil so that the air is slightly warmed before breathing. Then one need never stay in for the weather, even if one already has a cold.

Of course there are very delicate girls who need special care, but I am speaking to the average girl. Do not forget that a cold is a terrible thing, but also remember that it can be avoided by a little care at the right time, and by entire forgetfulness at other times.

Take plenty of exercise.

The more you can exercise in the open air the better. And if you take exercise you will find it possible to be out of doors on very cold days. If you are not strong on your feet, perhaps you are strong in the muscles for rowing. If you cannot row, perhaps you can ride. If you cannot ride, perhaps you can drive. If you cannot drive, perhaps you can exercise in the gymnasium. If you cannot do any of these things, do what you can. Walk from your door to the street and back again. Do the same thing over in fifteen minutes, and unless you are a miserable bon fide invalid your muscles will soon become more useful. Doing errands, and going about to people who need you, will give you valuable exercise for which you take no thought.But some of you are too busy to exercise many hours a day in the open air, and so you ought to be. The next best thing for you is housework. Perhaps you do not like that because you see it under the wrong angle of vision. Whether you like it or not, it is within reach of most of you, and would do you good.

But suppose your books and your sewing are necessary and keep you busy all day. Then you are to remember to change your position often. At the end of every hour, when you open the window, take a few deep breaths, stretch your arms and legs and fingers, and you will be better able to go on with your task.

Eat such food as you can thoroughly digest.

There are persons who are always troubled as to what they shall eat, and who, with all their care, are always ailing. I do not want you to think about your food so much that you can digest nothing, but I believe that a very little observation will teach you what is good for you individually. If you have a dizzy head, or rising of food, or a bad breath, or uneasiness of the bowels, you may be pretty sure that you have eaten something that disagrees with you, and by a little watchfulness you may discover what it is and avoid it.

Food that you can digest very well when you are fresh may be much too heavy for you when you are tired. And if you are thinking intently while you eat, the blood is drawn from the stomach where it should be to the brain where it should not be. Few people can digest vegetables not thoroughly cooked, or fruit not thoroughly ripe. I think the study of Physiology is of more practical hygienic value in teaching the absolute necessity of using food that can be readily assimilated by the body, and in showing how different foods should be combined to that end, than in any other way. A little fish or meat, especially beef, considerable bread, especially of the coarser grains, some vegetables, and fruit according to individual organizations, make up the necessary daily fare. A tired stomach should begin with soup. As for the thousand appetizing viands set before us, each must decide for herself what to eat. As long as you have none of the symptoms of indigestion, it is probably safe to gratify the appetite and take delight in food without further care; but if these symptoms appear, think first whether you were too tired, or had too busy a brain to digest anything; next, whether anything you ate was unripe or underdone, and finally, whether there was anything in the bill of fare which had ever troubled you before. Then correct your future practice accordingly, and think no more about it. Depend upon it, you will soon be well, and, further, you will find, with mortification perhaps, that some of the headaches you thought came from overtaxing the brain, or from sensibility to the woes of the world, were really due to improper food. As compensation for your mortification you will be a more useful woman for your whole life.

Work regularly with both body and mind.

Those who must work for self-support are probably, on the whole, in better health than those who are free from necessity. A girl who stands all day behind a counter runs some risks in health, but her chances are still as good as those of the fine lady who broods over imaginary ailments till they become real. To those who must work I have but little to say, for they have a narrow margin of choice. There are several suggestions to be made, however. If your work is physical, use a little of your leisure every day in some mental occupation. The best thing is to do some real studying. If you can only spend fifteen minutes every day on history or literature or botany or French, you will find yourself the better for it bodily, because it will give you an outlook beyond the daily horizon, and take your thoughts from your own weariness. If you have no leisure, or if your work is so exhausting that even fifteen minutes of study seems burdensome, then keep some interesting novel of good tone at hand, and read a little in that every day to change the current of your thoughts. If you find, however, that you usually have more than an hour for your novel, you may suspect that fifteen minutes of study would not hurt you.

Do you know that you are never resting when you are thinking that you are tired? When you are tired rest at once, if you can, by sitting or lying down, or taking recreation, as experience has shown you to be best. But then think no more about it. Perhaps you may be overworking. If you truly believe this and see any possibility of saving yourself, do so, even if you have to give up something which seems particularly important. If you must overwork,—and there are such cases, though they are not so common as we think,—accept the condition as a part of the discipline of life, rest whenever you can, and say and think as little about it as you can. This advice is to save you from one form of the nervous diseases which are the peculiar misfortune of our time.

If your work is sedentary take physical exercise in your leisure time,—out of doors, if possible; but remember that housework is the best substitute for that.

The women who are not obliged to work are those who most need this precept. They can drive, and by and by they cannot walk. They can lie on the lounge when they feel indisposed, and they lie there long after they would get up if they had any work to do. They have the best chance for complete physical development, but they have great temptations to neglect their opportunities. Among the sweetest of such women there is an alarming amount of nervous disease, which is, alas! at the foundation a refined selfishness. To speak plainly, as one has said, we are all as lazy as we dare to be, and these women have no check upon laziness. No power of body or mind can be preserved without exercise, and the muscles grow soft, and the moral fibre grows weak. These women are lovely, they speak in gentle voices, and they never use a harsh word, but they rule all about them with a rod of iron. Dr. Weir Mitchell, in his blunt way, says that nervous diseases among women have destroyed the happiness of more families than intemperance.

By and by the invalid cannot rally even if she has the will, but it is hard to decide where responsibility ends. If your mothers or your aunts are nervous invalids, do not judge them. Causes may have been at work which you cannot see. Pity their terrible misfortune, and do all you can to make them happy. But you, who have the added light of another generation, are inexcusable if you fall into such a state.

How can you avoid it? It is easy to say, "Do not talk about your headaches, or your delicate constitution;" but how are you to help thinking about these things? Decide on regular daily work for yourselves. If you are still school-girls and your head feels heavy in the morning, think whether you would be justified in staying at home if you were a teacher. Teachers have headaches too, but they seldom stay at home for one, and they are seldom the worse for going to school.When you leave school undertake some regular work. Take charge of the marketing, or oversee the housekeeping for a year. Ask the officers of the Associated Charities to give you something definite to do, and do it regularly. If you are not fitted for visiting the poor, suppose you make experiments in natural science. See what Lubbock did with ants, bees, and wasps. There are thousands of such experiments to be tried, but few people have the leisure for them. You may not understand your results, but you can make the accurate observations which are absolutely necessary before a great man can find out the laws which govern them.

Some mental work you must do. Of course you wish that. If you are in a city like Boston, I will tell you what you will be tempted to do. You will be tempted to sandwich your parties and calls and concerts with two or three courses of morning lectures given by highly trained specialists. In this way you will get a delightful society knowledge of history and literature and art and science, but you will not really exercise your mind very much. Your knowledge will be available for talk, but not for thought. Go to the lectures by all means,—though perhaps one course at a time will do; but be sure that every day at a fixed hour you study the subject of the lecture by yourself, and make it thoroughly your own.

Am I wandering from the topic of health? I think not, because during the last fifty years we have learned almost all the laws of health, and yet we are not much better than before, for our nerves are still on edge. Now girls, even rich girls, can control their nerves, if they begin soon enough, with will and intelligence. And nothing will help them more than to have their bodies and minds constantly employed in rational ways so that there is no room for nervous fancies.

Take the rest you need.

It is hard to know how much you need. Some people must have more than others. It is easy to be lazy on the one hand, and to be dissipated on the other. Some people are injured by springing out of bed as soon as they wake, and others by letting the time drift by while they doze. Some one gives this good rule, "Decide when you ought to rise to make the best use of your day. Make a point of rising at that time; but go to bed earlier and earlier till you find out how much sleep you need in order to be fresh at that hour in the morning." Such a rule would meet most cases, but not all; for though regularity is as important for health as for a wise life, it cannot be an iron regularity, especially if a girl is at all delicate. I would give more flexible rules, though it is harder to keep flexible rules than iron ones.

I have said before that when you are tired you should rest at once, if you can. Rest completely, but not long. Half an hour on the sofa is generally enough. Rise early, because an extra hour in the morning can be better used than one later in the day, and if duties crowd you get tired in remembering what you cannot do. But if you are not fresh in the morning, go to bed earlier. If that does not meet the case, your weariness probably comes from some other cause than insufficient rest. Perhaps your room is not well ventilated, or you may suffer from indigestion, or you may exercise your brain too much and your body too little. If you sit over books or sewing all day, you will always be tired however many hours you sleep. Most girls from fifteen to twenty need about nine hours sleep. If you wish to rise at six, you ought to be in bed at nine.

A few, a very few, of you must be invalids. You may have inherited a wasting disease, an accident may have crippled you, or something else beyond your control may have brought this misfortune upon you. But most of you have it in your power to be well, and remember you will be doing something morally wrong if you become feeble women.
