VI.—CONDITIONS OF HEALTHY BRAIN-ACTIVITY
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 [p 28] 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 [p 29] 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 schoolmistress 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 [p 30] 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!
Oxygen has its Limitations.—We know all about it; what we forget, perhaps, is, that even oxygen has its limitation: nothing can act but where it is, and, waste attends work, hold true for this vital gas as for other matters. Fire and lamp and breathing beings are all consumers of the oxygen which sustains them. What follows? Why, that this element, which is present in the ratio of twenty-three parts to the hundred in pure air, is subject to an enormous drain [p 31] within the four walls of a house, where the air is more or less stationary. I am not speaking just now of the vitiation of the air—only of the drain upon its life-sustaining element. Think, again, of the heavy drain upon the oxygen which must support the multitudinous fires and many breathing beings congregated in a large town! ‘What follows?’ is a strictly vital question. Man can enjoy the full measure of vigorous joyous existence possible to him only when his blood is fully aërated; and this takes place when the air he inhales contains its full complement of oxygen. Is it too much to say that vitality is reduced, other things being equal, in proportion as persons are house-dwellers rather than open-air dwellers? The impoverished air sustains life at a low and feeble level; wherefore, in the great towns, stature dwindles, the chest contracts, men hardly live to see their children’s children. True, we must needs have houses for shelter from the weather by day and for rest at night; but in proportion as we cease to make our houses ‘comfortable,’ as we regard them merely as necessary shelters when we cannot be out of doors, shall we enjoy to the full the vigorous vitality possible to us.

You will find an appendix with questions in the back of Home Education. These questions were for the students or persons preparing to become “Qualified Members” of the Parents’ National Educational Union. We put these questions on paper for you to use, if you’d like, as you ponder Mason’s writings. A new one will be available every Monday.
