joicing, only to repeat the same insane folly. But it is not good for one's credit to overdraw too frequently her bank account; and there may come a time when suspension means bankruptcy, and when all the kindness and skill of all our friends can be no longer of any avail. Is it not our own fault, and shall we not so educate our girls that they shall not fall into it, since they compre hend its unreason? We are undoubtedly creatures of habit; but we oftener apply the word to our mental and moral than to our physical nature, and wrongly. When regular and constant demands are made upon any organ of the body, the body, as it were, falls into the habit of laying in enough force in that particular department for that particular purpose, as the scientific steward at Vassar lays in for each day so many pounds of beef or mutton, because he can rely with certainty on its consumption. If in any case the demand is, for any reason, slackened, there is a surplus of energy which must find a vent, or render its possessor very uncomfortable. Need mothers be reminded of how very troublesome the little girl becomes in a short school vacation, or during the first days of a long one? Or need teachers be told that it is only a loss of time in the end, to assign at the commencement of the September-term lessons of the same length as those which were learned with no difficulty in June? There is a decided inertia in the bodily functions, and time is required for a sudden change. Inconvenience in such a case will be sure to arise, unless the surplus force be instantly directed into other and unobjectionable channels. If the reverse takes place, and the demand be suddenly increased, the result is weakness, debility, and finally disease; though precisely the same amount of work might have been done, not only with safety but with positive advantage, provided the increase of the demand. had been gradual. Is there any country in the world equal to America in the irregularity and spasmodic nature of the demands which society makes upon its women? Are there any girls in the world so ready to rush headlong into all kinds of exercise, mental or physical, which may be recommended to them, as our American girls? It is a pity that, to balance our greater amount of fiery energy in the matter of education, we have not a sounder philosophy. Once more, physical life is only a balance of forces, as spiritual life is a series of choices, and the question is not simply how much intellectual or brain work we are doing. This question cannot justly be considered apart from the other inquiry, of how much appropriate material we are supplying for the use of the brain. We cannot judge whether the amount of force expended be healthful or unhealthful till we know how much force has been and can be generated. There is undoubtedly a limit to this last factor in our problem, but if we do not exceed this limit in our expenditure, it seems unquestionable, that the more brain work we do, the better will it be for the entire system, and the stronger will be our health, this being only our power actively to resist the destructive forces of nature. The nervous system, at the head of which stands the brain, is undoubtedly the regent of the monarchy of the body, whose sovereign is the thinking spirit; and all the organs in a well-regulated body should be worked in the interest of the organ of thought, as servants for a wise and watchful master. It seems sometimes as if we were in danger of forgetting that though "the eye cannot say unto the hand, I have no need of thee, nor again, the head to the feet, I have no need of you," there will come a time when the thinking spirit, grown to full stature, shall say to all of them, "I have no need any longer of any of you." The consideration of the subject of Ventilation properly comes under this division, for pure air is as much food for the body, as meat or bread. This whole matter, however, seems to be practically not well understood, if we may judge from the results so far, and no extended. discussion of the means will be in place here. It is sufficient simply to indicate its immense importance. But that bad air is likely to be a more active cause of disease in America than elsewhere seems true, for in no other country are furnaces and closed fire-places in so general use. Moreover, the women and girls who spend most of their lives in the house, will be expected to show the evil effects more than the men and boys, who do not. The practical suggestions on this point are apparent to every one. One more thing which the body, to be healthy, demands for food is Sun-light, that invaluable medicine for all forms of nervous disease, which Americans, more than any other people, curtain carefully out for fear of fading carpets and furniture. But what are French moquettes, brocade, or satin, compared with rosy cheeks, clear complexions, and steady nerves? If we would only draw up the shades, open the shutters, and loop the heavy curtains out of the way, or, better still, take them down altogether, might we not look for a marked improvement in systems affected by nervous diseases? This want of sun-light may be expected also, of course, most to affect those who remain within doors, and who, even in walk ing, shade themselves with veils and sun-shades from the life-giving rays of the sun. Sleep. To many of the organs of the body there have been allotted seasons of comparative quiet and repose, even during the day. If the rules for food be observed, the stomach, for instance, has, as stomach, its vacations from labor, by means of which it is enabled to prepare for, and perform, its regularly recurring work with vigor. Even with organs where this is not the case, the action is slackened very materially at times, as in the case of the heart and lungs during sleep. They must continue to work, though more slowly, and the part of the nervous system which carries on their involuntary and mechanical action, has also then a partial relief. But the only rest for the thinking brain is to be found in normal sleep. From the instant when, in the morning, we become conscious of the external world, to the instant late at night, or, it may be, early in the morning, when we pass through the gates of sleep, out from companionship, into an utter solitude, it never rests from its work. Whether, by volition, we summon all our intellectual power to the closest attention, and turn, as it were, the whole energy of our being into one thought-channel, till the organs of sense become simply outside appendages which disturb the internal self with no imported knowledge, or whether, lying idly, as we say, on the sofa, we let our thoughts wander as they will, thought still goes on. Coming and going more rapidly than the shortest pendulum can swing, interweaving more subtly than the threads of the most complicated lace under the fingers of the skillful worker ; " trains of thought" pass and repass through our minds, following, as we mechanically express it, the Laws of Association. Only in losing consciousness, do we cease to destroy the brain cells; it is only in sleep that the brain can rest. But it must be remembered that the matter which is thus destroyed, is, as Maudsley* so finely shows, the very finest result of the creative life-process, the most precious essence. It is like the oil of roses, to produce one drop of which, unnumbered roses must be crushed. The force required to produce a nerve cell is said to be immeasur ably greater than that demanded for a cell of muscle, of bone, or of cartilage. In the nerve cells, lies not only the directive force of the whole complicated machinery, but the material with which the creative intelligence must work. Let us also remember that our waking hours far outnumber those spent in sleep, and we shall begin to realize the immense importance of sleep, even to the fully developed organism. But when we add to the mere labor of repairing the daily waste, the task of construction, which has to be performed during the years of growth, we shall only deepen the impression. I believe that every school-girl under eighteen years of age, and many over that age, should have at least nine hours of uninterrupted sleep in pure air, and the younger ones need even more. Much, at least doubtful, advice, has been given on the subject of early rising. That the system which has, perhaps, taken no food since six in the evening, should be ready for any amount of labor in the morning before breakfast, does not seem a rational conclusion, and I believe that many nervous diseases must be charged to the * Body and Mind, 2d Ed., p. 300. |
