Nearly all the captains, for instance, of our great trans-atlantic liners, whose duties in storm or fog keep them on the bridge on continuous duty for forty-eight, sixty, and even seventy-two hours at a stretch, with thousands of lives depending upon their courage and their judgment, are total abstainers. And while twenty-five years ago they used to think that they could not go through these long sieges of storm duty without plenty of wine or whiskey, they now find that they are far better off without any alcoholic drink.
Another powerful force in the same direction is our insurance companies, practically all of whom now will refuse to insure any man known habitually to use alcohol to excess, because where lists have been kept of their policy-holders showing which were users of alcohol and which total abstainers, their records show that the death rate among the users of alcohol is some twenty per cent greater than among the total abstainers. A similar result has also been reached in the companies that insure against sickness, whose drinking members average nearly twice as many weeks of sickness during the year as the abstaining ones. So both of these two great groups of business corporations are becoming powerful agencies for the promotion of temperance.
Within fifty years from now the habitual use of alcohol will probably have become quite rare. It is already becoming "good form" among the best people not to drink; and the fashion will spread, as the bad effects of alcohol become more generally understood.
TOBACCOSmoking, a Senseless Habit. Smoking is the curious act of drawing smoke into the mouth and puffing it out again. Why this custom should have become so widespread is even a greater puzzle than is the drinking of alcohol. In civilized countries at least, it is a custom of much more recent growth than "drinking," as it was introduced into Europe from America by the early explorers, notably those sent out by Sir Walter Raleigh. As tobacco-smoke is neither a solid nor a liquid, but only a gas, no one could even pretend that it is of any value, either as food or drink. All that can be said of smoking, even by the most inveterate smoker, is that it is a habit, of no possible use or value to body or mind, and of great possibilities of harm.
Another singular thing about smoking is that its effects vary so greatly according to the individual who practices it, that scarcely any two smokers can agree as to the exact reason why they smoke, except that in some vague way smoking gives them pleasure. The only thing that they do agree upon is that they miss it greatly, and crave it keenly whenever they stop it. The only thing that stands out clearly about smoking is that while it does no good, and does not even give one definite and uniform kind of pleasure, it does form a powerful and over-mastering habit, which is exceedingly difficult to break, and develops a craving which can be satisfied only by continuing, or returning, to it.
It is Very Difficult to Break the Habit of Smoking. As a matter of practical experience, not one smoker in fifty who tries to swear off ever succeeds in doing so permanently. Why then should any one form a habit, which is of no benefit whatever, which is expensive, unpleasant to others, and which may become exceedingly injurious, simply for the sake of saddling one's self with a craving which will probably never be got rid of all the rest of one's life? The strongest and most positive thing that a smoker can say about his pipe, or cigar, or cigarette, is that he could not get along without it; and he will usually add that he wishes he had never begun to use it. You are better off in every way by letting tobacco strictly alone, and never teaching yourself to like it.
Tobacco is Not a Natural Taste. As might be expected, in the case of such an utterly useless drug, we have no natural liking or instinct for it; and the taste for it has to be acquired just as in the case of alcohol, only as a rule with greater difficulty and with more painful experiences of headache, nausea, and other discomforts.
The Board of Health of the City of New York requires that all children between the ages of fourteen and sixteen shall have certificates of good health before they can be employed in business. Any employer who hires a child without such a certificate is liable to a heavy fine. This law is to protect the health of both the worker and the public.
Nicotine, a Powerful Poison. Tobacco contains and depends largely for its effects upon considerable amounts of a substance called nicotine. This is a powerful poison, even in very small doses, with only feeble narcotic, or pain-deadening, powers; but fortunately, the larger part of it is destroyed in the process of burning. Enough, however, is carried over in the smoke, or absorbed through the butt of the cigar or cigarette, or the mouth-piece of the pipe, to injure the nervous system, especially in youth. As will be seen in the chapter upon the "Care of the Heart," it especially attacks the nerves supplying the heart, and is thus most harmful to growing boys.
The boy who smokes cigarettes finds it increasingly difficult to obtain a position in a bank or other large commercial house.
On account of its injurious effects upon the nerves of the heart, smoking has long been forbidden by trainers and coachers to all athletes who are training for a contest or race. In addition to its poisonous effects upon the nervous system, tobacco also does great harm to boys and young men by providing them with an attractive means of filling up their time and keeping themselves amused without either bodily or mental effort. The boy who smokes habitually will find it much easier to waste his time in day-dreams and gossip, and tends to become a loafer and an idler.
The Advantage that Non-Smokers have over Smokers. When both of these influences are taken together, it is little wonder that the investigations of Dr. Seaver, the medical director of Yale, showed that out of the 187 men in the class of 1881, those not using tobacco during their college course had gained, over the users of tobacco, twenty-two per cent in weight, twenty-nine per cent in height, nineteen per cent in growth of chest, and sixty-six per cent in increase of lung capacity.
In the Amherst graduating class for the same year, the non-users of tobacco had gained twenty-four per cent more in weight, thirty-seven per cent more in height, and forty-two per cent more in growth of chest than had the smokers. In lung capacity, the tobacco users had lost two cubic inches, while the abstainers had gained six cubic inches.
As a wet-blanket upon ambition, a drag upon development, and a handicap upon success in life, the cigarette has few equals and no superiors. The stained fingers and sallow complexion of the youthful cigarette smoker will generally result in his being rejected when applying for a position. The employer knows that the non-smoking boy is much more likely to succeed in his work and win his way to a position of trust and influence than is the "cigarette fiend." Especially in these days of sharp competition, no boy can afford to contract a habit which will so handicap him in making his way as will the cigarette habit.
CHAPTER XI THE HEART-PUMP AND ITS PIPE-LINE SYSTEM THE BLOOD VESSELSWhere the Body Does its Real Eating. When once the food has been dissolved in the food-tube and absorbed by the cells of its walls, the next problem is how it shall be sent all over the body to supply the different parts that are hungry for it; for we must remember that the real eating of the food is done by the billions upon billions of tiny living cells of which the body is made up.
The Pipe Lines of the Body. What do we do when we want to carry water, or oil, or sewage, quickly and surely from one place to another? We put down a pipe line. We are wonderfully proud of our systems of water and gas supply, and of the great pipe lines that carry oil from wells in Ohio and Indiana clear to the Atlantic coast. But the very first man that ever laid a pipe to carry water was simply imitating nature—only about ten or fifteen million years behind her. No sooner has our food passed through the cells in the wall of the food-tube, than it goes straight into a set of tiny tubes—the blood-pipes, or blood vessels—which carry it to the heart; and the heart pumps it all over the body.
Veins and Arteries. These blood-tubes running from the walls of the food-tube to the heart are called veins; and the other tubes through which the heart pumps the blood all over the body are called arteries. If you will spell this last word "air-teries," it may help you to remember why the name was given to these tubes ages ago. When the body was examined after death, they were found to be empty and hence were not unnaturally supposed to carry air throughout the body, and "air-teries" they have remained ever since. While absurd in one way, the name is not so far amiss in another, for an important part of their work is to carry all over the body swarms of tiny baskets, or sponges, of oxygen taken from the air.
Why the Blood is Red. The first and main purpose of the blood-pipes and the heart is to carry the dissolved food from the stomach and intestines to the cells all over the body. But the cells need air as well as food; and, to carry this, there are little basket-cells—the red corpuscles. Take a drop of blood and put it under a microscope, and you will see what they look like. The field will be simply crowded with tiny, rounded lozenges—the red cells of the blood, which give it its well-known color.
BLOOD CORPUSCLES (Greatly magnified)
A, red blood; B, white blood.
The White Corpuscles or Scavengers of the Blood. As the blood-tubes are not only supply-pipes but sewers and drainage canals as well, it is a good thing to have some kind of tiny animals living and moving about in them, which can act as scavengers and eat up some of the waste and scraps; and hence your microscope will show you another kind of little blood corpuscle, known, from the fact that it is not colored, as the white corpuscle. These corpuscles are little cells of
