Rest after Meals.—The child has just had his dinner, the meal of the day which most severely taxes his digestive organs; for as much as two or three hours after, much labour is going on in these organs, and the blood that can be spared from elsewhere is present to assist. Now, send the child out for a long walk immediately after dinner—the blood goes to the labouring extremities, and the food is left half digested; give the child a regular course of such dinners and walks, and he will grow up a dyspeptic. Set him to his books after a heavy meal, and the case is as bad; the blood which should have been assisting in the digestion of the meal goes to the labouring brain.
It follows that the hours for lessons should be carefully chosen, after periods of mental rest—sleep or play, for instance—and when there is no excessive activity in any other part of the system. Thus, the morning, after breakfast (the digestion of which lighter meal is not a severe tax), is much the best time for lessons and every sort of mental work; if the whole afternoon cannot be spared for out-of-door recreation, that is the time for mechanical tasks such as needlework, drawing, practising; the children’s wits are bright enough in the evening, but the drawback to evening work is, that the brain, once excited, is inclined to carry on its labours beyond bed-time, and dreams, wakefulness, and uneasy sleep attend the poor child who has been at work until the last minute. If the elder children must work in the evening, they should have at least one or two pleasant social hours before they go to bed; but, indeed, we owe it to the children to abolish evening ‘preparation.’
Change of Occupation.—“There is,” says Huxley, “no satisfactory proof at present, that the manifestation of any particular kind of mental faculty is especially allotted to, or connected with, the activity of any particular region of the cerebral hemispheres,” a dictum against the phrenologists, but coming to us on too high authority to be disputed. It is not possible to localise the ‘faculties’—to say you are cautious with this fraction of your brain, and music-loving with another; but this much is certain, and is very important to the educator: the brain, or some portion of the brain, becomes exhausted when any given function has been exercised too long. The child has been doing sums for some time, and is getting unaccountably stupid: take away his slate and let him read history, and you find his wits fresh again. Imagination, which has had no part in the sums, is called into play by the history lesson, and the child brings a lively unexhausted power to his new work. School time-tables are usually drawn up with a view to give the brain of the child variety of work; but the secret of the weariness children often show in the home schoolroom is, that no such judicious change of lessons is contrived.
Nourishment.—Again, the brain cannot do its work well unless it be abundantly and suitably nourished; somebody has made a calculation of how many ounces of brain went to the production of such a work—say Paradise Lost—how many to such another, and so on. Without going into mental arithmetic of this nature, we may say with safety that every sort of intellectual activity wastes the tissues of the brain; a network of vessels supplies an enormous quantity of blood to the organ, to make up for this waste of material; and the vigour and health of the brain depend upon the quality and quantity of this blood-supply.
Certain Causes affect the Quality of the Blood.—Now, the quality of the blood is affected by three or four causes. In the first place, the blood is elaborated from the food; the more nutritious and easy of digestion the food, the more vital will be the properties of the blood. The food must be varied, too, a mixed diet, because various ingredients are required to make up for the various waste in the tissues. The children are shocking spendthrifts; their endless goings and comings, their restlessness, their energy, the very wagging of their tongues, all mean expenditure of substance: the loss is not appreciable, but they lose something by every sudden sally, out of doors or within. No doubt the gain of power which results from exercise is more than compensation for the loss of substance; but, all the same, this loss must be promptly made good. And not only is the body of the child more active, proportionably, than that of the man: the child’s brain as compared with the man’s is in a perpetual flutter of endeavour. It is calculated that though the brain of a man weighs no more than a fortieth part of his body, yet a fifth or a sixth of his whole complement of blood goes to nourish this delicate and intensely active organ; but, in the child’s case, a considerably larger proportion of the blood that is in him is spent on the sustenance of his brain. And all the time, with these excessive demands upon him, the child has to grow! not merely to make up for waste, but to produce new substance in brain and body.
Concerning Meals.—What is the obvious conclusion? That the child must be well fed. Half the people of low vitality we come across are the victims of low-feeding during their childhood; and that more often because their parents were not alive to their duty in this respect, than because they were not in a position to afford their children the diet necessary to their full physical and mental development. Regular meals at, usually, unbroken intervals—dinner, never more than five hours after breakfast; luncheon, unnecessary; animal food, once certainly, in some lighter form, twice a day—are the suggestions of common sense followed out in most well-regulated households. But it is not the food which is eaten, but the food which is digested, that nourishes body and brain. And here so many considerations press, that we can only glance at two or three of the most obvious. Everybody knows that children should not eat pastry, or pork, or fried meats, or cheese, or rich, highly-flavoured food of any description; that pepper, mustard, and vinegar, sauces and spices, should be forbidden, with new bread, rich cakes, and jams, like plum or gooseberry, in which the leathery coat of the fruit is preserved; that milk, or milk and water, and that not too warm, or cocoa, is the best drink for children, and that they should be trained not to drink until they have finished eating; that fresh fruit at breakfast is invaluable; that, as serving the same end, oatmeal porridge and treacle, and the fat of toasted bacon, are valuable breakfast foods; and that a glass of water, also, taken the last thing at night and the first thing in the morning, is useful in promoting those regular habits on which much of the comfort of life depends.
Talk at Meals.—All this and much of the same kind it is needless to urge; but again let me say, it is digested food that nourishes the system, and people are apt to forget how far mental and moral conditions affect the processes of digestion. The fact is, that the gastric juices which act as solvents to the viands are only secreted freely when the mind is in a cheerful and contented frame. If the child dislike his dinner, he swallows it, but the digestion of that distasteful meal is a laborious, much-impeded process: if the meal be eaten in silence, unrelieved by pleasant chat, the child loses much of the ‘good’ of his dinner. Hence it is not a matter of pampering them at all, but a matter of health, of due nutrition, that the children should enjoy their food, and that their meals should be eaten in gladness; though, by the way, joyful excitement is as mischievous as its opposite in destroying that even, cheerful tenor of mind favourable to the processes of digestion. No pains should be spared to make the hours of meeting round the family table the brightest hours of the day. This is supposing that the children are allowed to sit at the same table with their parents; and, if it is possible to let them do so at every meal excepting a late dinner, the advantage to the little people is incalculable. Here is the parents’ opportunity to train them in manners and in morals, to cement family love, and to accustom the children to habits, such as that of thorough mastication, for instance, as important on the score of health as on that of propriety.
Variety in Meals.—But, given pleasant surroundings and excellent food, and even then the requirements of these exacting little people are not fully met: plain as their food should be, they must have variety. A leg of mutton every Tuesday, the same cold on Wednesday, and hashed on Thursday, may be very good food; but the child who has this diet week after week is inadequately nourished, simply because he is tired of it. The mother should contrive a rotation for her children that will last at least a fortnight without the same dinner recurring twice. Fish, especially if the children dine off it without meat to follow, is excellent as a change, the more so as it is rich in phosphorus—a valuable brain food. The children’s puddings deserve a good deal of consideration, because they do not commonly care for fatty foods, but prefer to derive the warmth of their bodies from the starch and sugar of their puddings. But give them variety; do not let it be ‘everlasting tapioca.’ Even for tea and breakfast the wise mother does not say, ‘I always give my children’ so and so. They should not have anything ‘always’; every meal should have some little surprise. But is this the way, to make them think overmuch of what they shall eat and drink? On the contrary, it is the underfed children who are greedy, and unfit to be trusted with any unusual delicacy.
Air as important as Food.—The quality of the blood depends almost as much on the air we breathe as on the food we eat; in the course of every two or three minutes, all the blood in the body passes through the endless ramifications of the lungs, for no other purpose than that, during the instant of its passage, it should be acted upon by the oxygen contained in the air which is drawn into the lungs in the act of breathing. But what can happen to the blood in the course of an exposure of so short duration? Just this—the whole character, the very colour, of the blood is changed: it enters the lungs spoiled, no longer capable of sustaining life; it leaves them, a pure and vital fluid. Now, observe, the blood is only fully oxygenated when the air contains its full proportion of oxygen, and every breathing and every burning object withdraws some oxygen from the atmosphere. Hence the importance of giving the children daily airings and abundant exercise of limb and lung in unvitiated, unimpoverished air.
The Children Walk every Day.—‘The children walk every day; they are never out less than an hour when the weather is suitable.’ That is better than nothing; so is this:—An East London school-mistress notices the pale looks of one of her best girls. “Have you had any dinner, Nellie?” “Ye-es” (with hesitation). “What have you had?” “Mother gave Jessie and me a halfpenny to buy our dinners, and we bought a haporth of aniseed drops—they go further than bread”—with an appeal in her eyes against possible censure for extravagance. Children do not develop at their best upon aniseed drops for dinner, nor upon an hour’s ‘constitutional’ daily. Possibly science will bring home to us more and more the fact that animal life, pent under cover, is supported under artificial conditions, just as is plant life in a glass house. Here is where most Continental nations have the advantage over us; they keep up the habit of out-of-door life; and as a consequence, the average Frenchman, German, Italian, Bulgarian, is more joyous, more simple, and more hardy than the average Englishman. Climate? Did not Charles II.—and he knew—declare for the climate of England because you could be abroad “more hours in the day and more days in the year” in England than “in any other country”? We lose sight of the fact that we are not like that historical personage who “lived upon nothing but victuals and drink.” “You can’t live upon air!” we say to the invalid who can’t eat. No; we cannot live upon air; but, if we must choose among the three sustainers of life, air will support us the longest. We know all about it; we are deadly weary of the subject; let but the tail of your eye catch ‘oxygenation’ on a page, and the well-trained organ skips that paragraph of its own accord. No need to tell Macaulay’s schoolboy, or anybody else, how the blood of the body is brought to the lungs and there spread about in a huge extent of innumerable ‘pipes’ that it may be exposed momentarily to the oxygen in the air; how the air is made to blow upon the blood, so spread out in readiness, by the bellows-like action of breathing; how the air penetrates the very thin walls of the pipes; and then, behold, a magical (or chemical) transmutation; the worthless sewage of the system becomes on the instant the rich vivifying fluid whose function it is to build up the tissues of muscle and nerve. And the Prospero that wears the cloak? Oxygen, his name; and the marvel that he effects within us some fifteen times in the course of a minute is possibly without parallel in the whole array of marvels which we ‘tot up’ with easy familiarity, setting down ‘life,’ and carrying—a cypher!
