PHYSICAL EDUCATION
If we compare different kinds of animals, or different races of men, or the same animals or men when differently fed, we find still more distinct proof that _the degree of energy essentially depends on the nutritiveness of the food_. In a cow, subsisting on so innutritive a food as grass, we see that the immense quantity required necessitates an enormous digestive system; that the limbs, small in comparison with the body, are burdened by its weight; that in carrying about this heavy body and digesting this excessive quantity of food, much force is expended; and that, having but little remaining, the creature is sluggish. Compare with the cow a horse--an animal of nearly allied structure, but habituated to a more concentrated diet. Here the body, and more especially its abdominal region, bears a smaller ratio to the limbs; the powers are not taxed by the support of such massive viscera, nor the digestion of so bulky a food; and, as a consequence, there is greater locomotive energy and considerable vivacity. If, again, we contrast the stolid inactivity of the graminivorous sheep with the liveliness of the dog, subsisting on flesh or farinaceous matters, or a mixture of the two, we see a difference similar in kind, but still greater in degree. And after walking through the Zoological Gardens, and noting the restlessness with which the carnivorous animals pace up and down their cages, it needs but to remember that none of the herbivorous animals habitually display this superfluous energy, to see how clear is the relation between concentration of food and degree of activity.
That these differences are not directly consequent on differences of constitution, as some may argue; but are directly consequent on differences in the food which the creatures are constituted to subsist on; is proved by the fact, that they are observable between different divisions of the same species. The varieties of the horse furnish an illustration. Compare the big-bellied, inactive, spiritless cart-horse with a racer or hunter, small in the flanks and full of energy; and then call to mind how much less nutritive is the diet of the one than that of the other. Or take the case of mankind. Australians, Bushmen, and others of the lowest savages who live on roots and berries, varied by larvae of insects and the like meagre fare, are comparatively puny in stature, have large abdomens, soft and undeveloped muscles, and are quite unable to cope with Europeans, either in a struggle or in prolonged exertion. Count up the wild races who are well grown, strong and active, as the Kaffirs, North-American Indians, and Patagonians, and you find them large consumers of flesh. The ill-fed Hindoo goes down before the Englishman fed on more nutritive food; to whom he is as inferior in mental as in physical energy. And generally, we think, the history of the world shows that the well-fed races have been the energetic and dominant races.
Still stronger, however, becomes the argument, when we find that the same individual animal is capable of more or less exertion according as its food is more or less nutritious. This has been demonstrated in the case of the horse. Though flesh may be gained by a grazing horse, strength is lost; as putting him to hard work proves. "The consequence of turning horses out to grass is relaxation of the muscular system." "Grass is a very good preparation for a bullock for Smithfield market, but a very bad one for a hunter." It was well known of old that, after passing the summer in the fields, hunters required some months of stable-feeding before becoming able to follow the hounds; and that they did not get into good condition till the beginning of the next spring. And the modern practice is that insisted on by Mr. Apperley--"Never to give a hunter what is called 'a summer's run at grass,' and, except under particular and very favourable circumstances, never to turn him out at all." That is to say, never give him poor food: great energy and endurance are to be obtained only by the continued use of nutritive food. So true is this that, as proved by Mr. Apperley, prolonged high-feeding enables a middling horse to equal, in his performances, a first-rate horse fed in the ordinary way. To which various evidences add the familiar fact that, when a horse is required to do double duty, it is the practice to give him beans--a food containing a larger proportion of nitrogenous, or flesh-making material, than his habitual oats.
Once more, in the case of individual men the truth has been illustrated with equal, or still greater, clearness. We do not refer to men in training for feats of strength, whose regimen, however, thoroughly conforms to the doctrine. We refer to the experience of railway-contractors and their labourers. It has been for years a well-established fact that an English navvy, eating largely of flesh, is far more efficient than a Continental navvy living on farinaceous food: so much more efficient, that English contractors for Continental railways found it pay to take their labourers with them. That difference of diet and not difference of race caused this superiority, has been of late distinctly shown. For it has turned out, that when the Continental navvies live in the same style as their English competitors, they presently rise, more or less nearly, to a par with them in efficiency. And to this fact let us here add the converse one, to which we can give personal testimony based upon six months' experience of vegetarianism, that abstinence from meat entails diminished energy of both body and mind.
Do not these various evidences endorse our argument respecting the feeding of children? Do they not imply that, even supposing the same stature and bulk to be attained on an innutritive as on a nutritive diet, the quality of tissue is greatly inferior? Do they not establish the position that, where energy as well as growth has to be maintained, it can only be done by high feeding? Do they not confirm the _à priori_ conclusion that, though a child of whom little is expected in the way of bodily or mental activity, may thrive tolerably well on farinaceous substances, a child who is daily required, not only to form the due amount of new tissue, but to supply the waste consequent on great muscular action, and the further waste consequent on hard exercise of brain, must live on substances containing a larger ratio of nutritive matter? And is it not an obvious corollary, that denial of this better food will be at the expense either of growth, or of bodily activity, or of mental activity; as constitution and circumstances determine? We believe no logical intellect will question it. To think otherwise is to entertain in a disguised form the old fallacy of the perpetual-motion schemers--that it is possible to get power out of nothing.
Before leaving the question of food, a few words must be said on another requisite--_variety_. In this respect the dietary of the young is very faulty. If not, like our soldiers, condemned to "twenty years of boiled beef," our children have mostly to bear a monotony which, though less extreme and less lasting, is quite as clearly at variance with the laws of health. At dinner, it is true, they usually have food that is more or less mixed, and that is changed day by day. But week after week, month after month, year after year, comes the same breakfast of bread-and-milk, or, it may be, oatmeal-porridge. And with like persistence the day is closed, perhaps with a second edition of the bread-and-milk, perhaps with tea and bread-and-butter. This practice is opposed to the dictates of physiology. The satiety produced by an often-repeated dish, and the gratification caused by one long a stranger to the palate, are _not_ meaningless, as people carelessly assume; but they are the incentives to a wholesome diversity of diet. It is a fact, established by numerous experiments, that there is scarcely any one food, however good, which supplies in due proportions or right forms all the elements required for carrying on the vital processes in a normal manner: whence it follows that frequent change of food is desirable to balance the supplies of all the elements. It is a further fact, known to physiologists, that the enjoyment given by a much-liked food is a nervous stimulus, which, by increasing the action of the heart and so propelling the blood with increased vigour, aids in the subsequent digestion. And these truths are in harmony with the maxims of modern cattle-feeding, which dictate a rotation of diet.
Not only, however, is periodic change of food very desirable; but, for the same reasons, it is very desirable that a mixture of food should be taken at each meal. The better balance of ingredients, and the greater nervous stimulation, are advantages which hold here as before. If facts are asked for, we may name as one, the comparative ease with which the stomach disposes of a French dinner, enormous in quantity but extremely varied in materials. Few will contend that an equal weight of one kind of food, however well cooked, could be digested with as much facility. If any desire further facts, they may find them in every modern book on the management of animals. Animals thrive best when each meal is made up of several things. The experiments of Goss and Stark "afford the most decisive proof of the advantage, or rather the necessity, of a mixture of substances, in order to produce the compound which is the best adapted for the action of the stomach."[3] Should any object, as probably many will, that a rotating dietary for children, and one which also requires a mixture of food at each meal, would entail too much trouble; we reply, that no trouble is thought too great which conduces to the mental development of children, and that for their future welfare, good bodily development is of still higher importance. Moreover, it seems alike sad and strange that a trouble which is cheerfully taken in the fattening of pigs, should be thought too great in the rearing of children.
One more paragraph, with the view of warning those who may propose to adopt the regimen indicated. The change must not be made suddenly; for continued low-feeding so enfeebles the system, as to disable it from at once dealing with a high diet. Deficient nutrition is itself a cause of dyspepsia. This is true even of animals. "When calves are fed with skimmed milk, or whey, or other poor food, they are liable to indigestion."[4] Hence, therefore, where the energies are low, the transition to a generous diet must be gradual: each increment of strength gained, justifying a fresh addition of nutriment. Further, it should be borne in mind that the concentration of nutriment may be carried too far. A bulk sufficient to fill the stomach is one requisite of a proper meal; and this requisite negatives a diet deficient in those matters which give adequate mass. Though the size of the digestive organs is less in the well-fed civilised races than in the ill-fed savage ones, and though their size may eventually diminish still further, yet, for the time being, the bulk of the ingesta must be determined by the existing capacity. But, paying due regard to these two qualifications, our conclusions are--that the food of children should be highly nutritive; that it should be varied at each meal and at successive meals; and that it should be abundant.
Among the sensations serving for our guidance are those of heat and cold; and a clothing for children which does not carefully consult these sensations, is to be condemned. The common notion about "hardening" is a grievous delusion. Not a few children are "hardened" out of the world; and those who survive, permanently suffer either in growth or constitution. "Their delicate appearance furnishes ample indication of the mischief thus produced, and their frequent attacks of illness might prove a warning even to unreflecting parents," says Dr. Combe. The reasoning on which this hardening-theory rests is extremely superficial. Wealthy parents, seeing little peasant boys and girls playing about in the open air only half-clothed, and joining with this fact the general healthiness of labouring people, draw the unwarrantable conclusion that the healthiness is the result of the exposure, and resolve to keep their own offspring scantily covered! It is forgotten that these urchins who gambol upon village-greens are in many respects favourably circumstanced--that their lives are spent in almost perpetual play; that they are all day breathing fresh air; and that their systems are not disturbed by over-taxed brains. For aught that appears to the contrary, their good health may be maintained, not in consequence of, but in spite of, their deficient clothing. This alternative conclusion we believe to be the true one; and that an inevitable detriment results from the loss of animal heat to which they are subject.
For when, the constitution being sound enough to bear it, exposure does produce hardness, it does so at the expense of growth. This truth is displayed alike in animals and in man. Shetland ponies bear greater inclemencies than the horses of the south, but are dwarfed. Highland sheep and cattle, living in a colder climate, are stunted in comparison with English breeds. In both the arctic and antarctic regions the human race falls much below its ordinary height: the Laplander and Esquimaux are very short; and the Terra del Fuegians, who go naked in a wintry land, are described by Darwin as so stunted and hideous, that "one can hardly make one's-self believe they are fellow-creatures." Science explains this dwarfishness produced by great abstraction of heat; showing that, food and other things being equal, it unavoidably results. For, as before pointed out, to make up for that cooling by radiation which the body is ever undergoing, there must be a constant oxidation of certain matters forming part of the food. And in proportion as the thermal loss is great, must the quantity of these matters required for oxidation be great. But the power of the digestive organs is limited. Consequently, when they have to prepare a large quantity of this material needful for maintaining the temperature, they can prepare but a small quantity of the material which goes to build up the frame. Excessive expenditure for fuel entails diminished means for other purposes. Wherefore there necessarily results a body small in size, or inferior in texture, or both.
Hence the great importance of clothing. As Liebig says:--"Our clothing is, in reference to the temperature of the body, merely an equivalent for a certain amount of food." By diminishing the loss of heat, it diminishes the amount of fuel needful for maintaining the heat; and when the stomach has less to do in preparing fuel, it can do more in preparing other materials. This deduction is confirmed by the experience of those who manage animals. Cold can be borne by animals only at an expense of fat, or muscle, or growth, as the case may be. "If fattening cattle are exposed to a low temperature, either their progress must be retarded, or a great additional expenditure of food incurred."[5] Mr. Apperley insists strongly that, to bring hunters into good condition, it is necessary that the stable should be kept warm. And among those who rear racers, it is an established doctrine that exposure is to be avoided.
The scientific truth thus illustrated by ethnology, and recognised by agriculturists and sportsmen, applies with double force to children. In proportion to their smallness and the rapidity of their growth is the injury from cold great. In France, new-born infants often die in winter from being carried to the office of the _maire_ for registration. "M. Quetelet has pointed out, that in Belgium two infants die in January for one that dies in July." And in Russia the infant mortality is something enormous. Even when near maturity, the undeveloped frame is comparatively unable to bear exposure: as witness the quickness with which young soldiers succumb in a trying campaign. The _rationale_ is obvious. We have already adverted to the fact that, in consequence of the varying relation between surface and bulk, a child loses a relatively larger amount of heat than an adult; and here we must point out that the disadvantage under which the child thus labours is very great. Lehmann says:--"If the carbonic acid excreted by children or young animals is calculated for an equal bodily weight, it results that children produce nearly twice as much acid as adults." Now the quantity of carbonic acid given off varies with tolerable accuracy as the quantity of heat produced. And thus we see that in children the system, even when not placed at a disadvantage, is called upon to provide nearly double the proportion of material for generating heat.
See, then, the extreme folly of clothing the young scantily. What father, full-grown though he is, losing heat less rapidly as he does, and having no physiological necessity but to supply the waste of each day--what father, we ask, would think it salutary to go about with bare legs, bare arms, and bare neck? Yet this tax on the system, from which he would shrink, he inflicts on his little ones, who are so much less able to bear it! or, if he does not inflict it, sees it inflicted without protest. Let him remember that every ounce of nutriment needlessly expended for the maintenance of temperature, is so much deducted from the nutriment going to build up the frame; and that even when colds, congestions, or other consequent disorders are escaped, diminished growth or less perfect structure is inevitable. "The rule is, therefore, not to dress in an invariable way in all cases, but to put on clothing in kind and quantity _sufficient in the individual case to protect the body effectually from an abiding sensation of cold, however slight_." This rule, the importance of which Dr. Combe indicates by the italics, is one in which men of science and practitioners agree. We have met with none competent to form a judgment on the matter, who do not strongly condemn the exposure of children's limbs. If there is one point above others in which "pestilent custom" should be ignored, it is this.
Lamentable, indeed, is it to see mothers seriously damaging the constitutions of their children out of compliance with an irrational fashion. It is bad enough that they should themselves conform to every folly which our Gallic neighbours please to initiate; but that they should clothe their children in any mountebank dress which _Le petit Courrier des Dames_ indicates, regardless of its insufficiency and unfitness, is monstrous. Discomfort, more or less great, is inflicted; frequent disorders are entailed; growth is checked or stamina undermined; premature death not uncommonly caused; and all because it is thought needful to make frocks of a size and material dictated by French caprice. Not only is it that for the sake of conformity, mothers thus punish and injure their little ones by scantiness of covering; but it is that from an allied motive they impose a style of dress which forbids healthful activity. To please the eye, colours and fabrics are chosen totally unfit to bear that rough usage which unrestrained play involves; and then to prevent damage the unrestrained play is interdicted. "Get up this moment: you will soil your clean frock," is the mandate issued to some urchin creeping about on the floor.
"Come back: you will dirty your stockings," calls out the governess to one of her charges, who has left the footpath to scramble up a bank. Thus is the evil doubled. That they may come up to their mamma's standard of prettiness, and be admired by her visitors, children must have habiliments deficient in quantity and unfit in texture; and that these easily-damaged habiliments may be kept clean and uninjured, the restless activity so natural and needful for the young is restrained. The exercise which becomes doubly requisite when the clothing is insufficient, is cut short, lest it should deface the clothing. Would that the terrible cruelty of this system could be seen by those who maintain it! We do not hesitate to say that, through enfeebled health, defective energies, and consequent non-success in life, thousands are annually doomed to unhappiness by this unscrupulous regard for appearances: even when they are not, by early death, literally sacrificed to the Moloch of maternal vanity. We are reluctant to counsel strong measures, but really the evils are so great as to justify, or even to demand, a peremptory interference on the part of fathers. Our conclusions are, then--that, while the clothing of children should never be in such excess as to create oppressive warmth, it should always be sufficient to prevent any general feeling of cold;[6] that, instead of the flimsy cotton, linen, or mixed fabrics commonly used, it should be made of some good non-conductor, such as coarse woollen cloth; that it should be so strong as to receive little damage from the hard wear and tear which childish sports will give it; and that its colours should be such as will not soon suffer from use and exposure.
But we have been obliged to qualify this admission by inserting the clause "in so far as boys are concerned." Unfortunately the fact is quite otherwise with girls. It chances, somewhat strangely, that we have daily opportunity of drawing a comparison. We have both a boys' school and a girls' school within view; and the contrast between them is remarkable. In the one case, nearly the whole of a large garden is turned into an open, gravelled space, affording ample scope for games, and supplied with poles and horizontal bars for gymnastic exercises. Every day before breakfast, again towards eleven o'clock, again at mid-day, again in the afternoon, and once more after school is over, the neighbourhood is awakened by a chorus of shouts and laughter as the boys rush out to play; and for as long as they remain, both eyes and ears give proof that they are absorbed in that enjoyable activity which makes the pulse bound and ensures the healthful activity of every organ. How unlike is the picture offered by the "Establishment for Young Ladies!" Until the fact was pointed out, we actually did not know that we had a girl's school as close to us as the school for boys. The garden, equally large with the other, affords no sign whatever of any provision for juvenile recreation; but is entirely laid out with prim grass-plots, gravel-walks, shrubs, and flowers, after the usual suburban style. During five months we have not once had our attention drawn to the premises by a shout or a laugh. Occasionally girls may be observed sauntering along the paths with lesson-books in their hands, or else walking arm-in-arm. Once indeed, we saw one chase another round the garden; but, with this exception, nothing like vigorous exertion has been visible.
Why this astounding difference? Is it that the constitution of a girl differs so entirely from that of a boy as not to need these active exercises? Is it that a girl has none of the promptings to vociferous play by which boys are impelled? Or is it that, while in boys these promptings are to be regarded as stimuli to a bodily activity without which there cannot be adequate development, to their sisters, Nature has given them for no purpose whatever--unless it be for the vexation of school-mistresses? Perhaps, however, we mistake the aim of those who train the gentler sex. We have a vague suspicion that to produce a robust _physique_ is thought undesirable; that rude health and abundant vigour are considered somewhat plebeian; that a certain delicacy, a strength not competent to more than a mile or two's walk, an appetite fastidious and easily satisfied, joined with that timidity which commonly accompanies feebleness, are held more lady-like. We do not expect that any would distinctly avow this; but we fancy the governess-mind is haunted by an ideal young lady bearing not a little resemblance to this type. If so, it must be admitted that the established system is admirably calculated to realise this ideal. But to suppose that such is the ideal of the opposite sex is a profound mistake. That men are not commonly drawn towards masculine women, is doubtless true. That such relative weakness as asks the protection of superior strength, is an element of attraction, we quite admit. But the difference thus responded to by the feelings of men, is the natural, pre-established difference, which will assert itself without artificial appliances. And when, by artificial appliances, the degree of this difference is increased, it becomes an element of repulsion rather than of attraction.
