It is a wonder that we live at all. We violate every law of our being, yet we expect to live to a ripe old age. What would you think of a man who, having an elegant watch delicately adjusted to heat and cold, should leave it on the sidewalk with cases open on a dusty or a rainy day, and yet expect it to keep good time? What would you think of a householder who should leave the doors and windows of his mansion open to thieves and tramps, to winds and dust and rain?

What are our bodies but timepieces made by an Infinite Hand, wound up to run a century, and so delicately adjusted to heat and cold that the temperature will not vary half a degree between the heat of summer and the cold of winter whether we live in the regions of eternal frost or under the burning sun of the tropics? A particle of dust or the slightest friction will throw this wonderful timepiece out of order, yet we often leave it exposed to all the corroding elements. We do not always keep open the twenty-five miles of ventilating pores in the skin by frequent bathing. We seldom lubricate the delicate wheels of the body with the oil of gladness. We expose it to dust and cinders, cold and draughts, and poisonous gases.

How careful we are to filter our water, air our beds, ventilate our sleeping-rooms, and analyze our milk! We shrink from contact with filth and disease. But we put paper colored with arsenic on our walls, and daily breathe its poisonous exhalations. We frequent theaters crowded with human beings, many of whom are uncleanly and diseased. We sit for hours and breathe in upon fourteen hundred square feet of lung tissue the heated, foul, and heavy air; carbonic acid gas from hundreds of gas burners, each consuming as much oxygen as six people; air filled with shreds of tissue expelled from diseased lungs; poisonous effluvia exhaled from the bodies of people who rarely bathe, from clothing seldom washed, fetid breaths, and skin disease in different stages of development. For hours we sit in this bath of poison, and wonder at our headache and lassitude next morning.

We pour a glass of ice water into a stomach busy in the delicate operation of digestion, ignorant or careless of the fact that it takes half an hour to recover from the shock and get the temperature back to ninety-eight degrees, so that the stomach can go on secreting gastric juice. Then down goes another glass of water with similar results.

We pour down alcohol which thickens the velvety lining of the stomach, and hardens the soft tissues, the thin sheaths of nerves, and the gray matter of the brain. We crowd meats, vegetables, pastry, confectionery, nuts, raisins, wines, fruits, etc., into one of the most delicately constructed organs of the body, and expect it to take care of its miscellaneous and incongruous load without a murmur.

After all these abuses we do not give the blood a chance to go to the stomach and help it out of its misery, but summon it to the brain and muscles, notwithstanding the fact that it is so important to have an extra supply to aid digestion that Nature has made the blood vessels of the alimentary canal large enough to contain several times the amount in the entire body.

Who ever saw a horse leave his oats and hay, when hungry, to wash them down with water? The dumb beasts can teach us some valuable lessons in eating and drinking. Nature mixes our gastric juice or pepsin and acids in just the right proportion to digest our food, and keep it at exactly the right temperature. If we dilute it, or lower its temperature by ice water, we diminish its solvent or digestive power, and dyspepsia is the natural result.

English factory children have received the commiseration of the world because they were scourged to work fourteen hours out of the twenty-four. But there is many a theoretical republican who is a harsher taskmaster to his stomach than this; who allows it no more resting time than he does his watch; who gives it no Sunday, no holiday, no vacation in any sense, and who seeks to make his heart beat faster for the sake of the exhilaration he can thus produce.

Although the heart weighs a little over half a pound, yet it pumps eighteen pounds of blood from itself, forcing it into every nook and corner of the entire body, back to itself in less than two minutes. This little organ, the most perfect engine in the world, does a daily work equal to lifting one hundred and twenty-four tons one foot high, and exerts one-third as much muscle power as does a stout man at hard labor. If the heart should expend its entire force lifting its own weight, it would raise itself nearly twenty thousand feet an hour, ten times as high as a pedestrian can lift himself in ascending a mountain. What folly, then, to goad this willing, hard-working slave to greater exertions by stimulants!

We must pay the penalty of our vocations. Beware of work that kills the workman. Those who prize long life should avoid all occupations which compel them to breathe impure air or deleterious gases, and especially those in which they are obliged to inhale dust and filings from steel and brass and iron, the dust in coal mines, and dust from threshing machines. Stone-cutters, miners, and steel grinders are short lived, the sharp particles of dust irritating and inflaming the tender lining of the lung cells. The knife and fork grinders in Manchester, England, rarely live beyond thirty-two years. Those who work in grain elevators and those who are compelled to breathe chemical poisons are short lived.
