AUTHOR'S NOTE TO THE PUPIL

This book has been prepared to help you in learning about "the house you live in," and to teach you to take care of it, and keep it from being destroyed by two of its greatest enemies,—Alcohol and Nicotine.

As you study its pages, be sure to find out the meaning of every word in them which you do not understand; for, if you let your tongue say what your mind knows nothing about, you are talking parrot-fashion.

And do not forget that you must pay for all the knowledge you obtain, whether you are rich or poor. Nobody else can pay for you. You, your own self, must pay attention with your own mind, through your own eyes and ears, or do without knowledge.

Be wise: gain all the knowledge you can concerning everything worth knowing, and use it for the good of yourself and other people.

"KNOWLEDGE IS POWER."



PART I.

FORMULA FOR INTRODUCTORY LESSONS.

1. My body is built of bones covered with flesh and skin; the blood flows through it, all the time, from my heart. I breathe through my nose and mouth, and take the air into my lungs.

2. The parts of my body are the head, the trunk, the limbs.

3. My head. The crown of my head. The back of my head. The sides of my head. My face. My forehead. My two temples. My two eyes. My nose. My two cheeks. My mouth. My chin. My two ears. My neck. My two shoulders. My two arms. My two hands. My trunk. My back. My two sides. My chest. My two legs. My two knees. My two feet. I am sitting erect.

* * * * *

QUESTIONS FOR THE FORMULA.

1. Tell about your body.

2. Name the parts of the body.

3. Name the parts of the head, trunk, and limbs.

* * * * *

THE NOSE AND THE MOUTH.

Be sure to keep your mouth closed when you are not talking or singing, especially when you are walking, running, or asleep. The two nostrils are outside doors, always open to admit the air, and inside of the upper part of the nose there are two other openings, through which it passes into the throat. Air which goes this way is warmed, cleansed, and moistened, but that which is breathed directly through the mouth is not so well prepared for its work in the lungs.

Do not use your mouth as a box or a pin-cushion; the pin, or whatever yon have put into it, may slip into your throat and cause your death.

5. Tell about your foot.

* * * * *



Some joints, as those of the skull, are immovable; some, as those of the spine, may be moved a little; and others more or less freely, as those of the limbs. In machines, the parts which move upon each other need to be oiled, to keep them from wearing out; but the joints of our bodies oil themselves with a thin fluid, called synovia. This fluid resembles the white of an egg, and comes from a smooth lining inside of the joints. The ends of the bones which form joints are covered by gristle or cartilage, and are fastened together by very strong, silvery white bands, called ligaments. A sprain is caused by overstretching or tearing some of these ligaments.

EXERCISE FOR COUNTING THE BONES OF THE HAND.

FOR PRIMARY CLASSES.

I.

1. Close both hands.

2. Raise the forefinger of the right hand, as the index or pointing finger.

3. Place the index finger upon the lower thumb joint of the left hand.

4. Draw the index finger down to the wrist, over the bone between the thumb knuckle and the wrist, and count "One."

5. Place the index finger on the knuckle of the first finger.

6. Draw the index finger down to the wrist, over the bone leading from the first finger to the wrist, and count "Two."

7. So on, for each of the three other bones of the hand. Repeat until no mistake is made in touching or counting.

II.

1. Raise the thumb, and place the index finger of the right hand on the middle of the upper part of the thumb for bone "Six"; then

2. On the lower part of the thumb for bone "Seven." Repeat from the beginning, until the children can touch and count each bone properly.

III.

1. Keep the thumb erect; raise the first finger of the left hand.

2. Place the index finger on the bone between the tip and the first joint of the first finger for bone "Eight."

3. Between the first and middle joint for bone "Nine."

4. Between the middle and third joint for bone "Ten." Review, from the beginning, until the class can touch and count every bone as directed.

IV.

1. Keep the thumb and forefinger erect; raise the second finger and touch, as in the lesson on the first finger bones, "Eleven," "Twelve," and "Thirteen." Review.

2. Proceed in the same manner for the third and fourth fingers, always beginning with the bone nearest the tip of the finger, and touching that at the lowest part last.

If the exercise has been properly performed, every child will say "Nineteen" as its index finger touches the lowest bone of the little finger, and all the fingers of every left hand will be outspread.

* * * * *

THE BONES

OF THE HEAD: Skull 8 Face, including the lower jaw 14 Tongue 1 Ears 8 —— 31 OF THE TRUNK: Spine 24 Ribs 24 Breastbone 8 Shoulder blades 2 Collar bones 2 —— 60 OF THE UPPER LIMBS: Upper arms 1 x 2 = 2 Fore-arms 2 x 2 = 4 Wrists 8 x 2 = 16 Hands 19 x 2 = 38 —— 60 OF THE LOWER LIMBS: Thighs 1 x 2 = 2 Knee-pans 1 x 2 = 2 Lower legs 2 x 2 = 4 Feet 26 x 2 = 52 —— 60

Total, 211, not including the teeth.[1]

We teach the children to say "about two hundred," because there is not always the same number of bones in the body. In some parts two or three bones unite and form one bone. For example: the breastbone of a child is made up of eight pieces; some of these unite as it becomes older, so that when fully grown it has but three pieces in this bone.

[1] The teeth are not bone, but a kind of soft, bone-like substance, called dentine. Common ivory is dentine.

PART IV.

FORMULAS FOR THE LESSONS ON THE ORGANS OF SENSE.

1. The Eyes.—My eyes are to see with.

My eye is like a ball in a deep, bony socket. The black circle in the centre is the pupil or window of my eye; the colored ring is the iris or curtain; the white part is the eyeball.

My upper and lower eyelids cover and protect my eyes.

My eyebrows are for beauty, and keep the perspiration from rolling into my eyes.

My eyes are washed by teardrops every time I wink my eyelids.

2. The Ears.—My ears are to hear with:

the rim of my ear, the flap of my ear, the drum of my ear.

The drum of my ear is protected by a fence of short, stiff hairs, and by a bitter wax about the roots of these hairs.

3. The Nose.—My nose is to smell and breathe with; it is in the middle of my face:

my two nostrils, the bridge of my nose, the cartilage, the tip of my nose.

My nostrils lead to a passage back of my mouth through which I breathe.

The cartilage separates my nose into two parts.

4. The Mouth.—My mouth is to speak, eat, and breathe through:

my upper lip, my lower lip.

In my mouth are:

my tongue, my lower teeth, my upper teeth, my lower teeth, and my upper and lower jaws, covered with flesh called gum.

5. The Teeth.—My teeth are used in eating and talking.

My teeth are made of a soft kind of bone, covered with enamel.

I have three kinds of teeth: cutting teeth, tearing teeth, grinding teeth.

A young child has twenty teeth, ten in each jaw.

A grown person has thirty-two teeth, sixteen in each jaw.

6. To preserve my teeth:

I must keep them clean. I must not scratch the enamel. I must not eat or drink anything very hot or very cold. I must not use them for scissors or nut-crackers. I must not burn them with tobacco or cigars.

7. About Eating.—When I eat I move my lower jaw only.

My tongue brings the food between my teeth, the cutters cut it, the tearers tear it, the grinders grind it, the saliva moistens it, and my tongue helps me to swallow it.

* * * * *

PART V.

FORMULA FOR DESCRIPTION OF THE BONES.

1. My skull is formed of several bones united, like two saws with their toothed edges hooked into each other.

2. My spine extends from the base of the skull behind, down the middle of my back.

It is composed of twenty-four short bones, piled one upon the other, with cartilage between them.

These bones are fastened together, forming an upright and flexible column, which makes me erect and graceful.

3. My ribs are curved, strong, and light; there are twenty-four of them, twelve on each side; they are fastened at the back to my spine, in front to my breastbone, forming a hollow place for my heart, lungs, and stomach.

4. My shoulder blades are flat, thin, and like a triangle in shape; they are for my arms to rest upon.

5. My collar bones are fastened to my shoulder blades and my breastbone; they keep my arms from sliding too far forward.

6. The bones of old people are hard and brittle; those of children soft and flexible; so I must sit and stand erect, that mine may not be bent out of shape. I must not wear tight clothing, or do anything that will crowd them out of their places.

7. My bones are made from my food, after it has been changed into blood; so I must be careful to eat good, wholesome food, that they may be strong and healthy.

8. I must not breathe impure air, because impure air makes bad blood, and bad blood makes poor bones.

9. The body of every person is changing all the time, because the skin, flesh, and bones are always wearing out, and the blood is always repairing and building them again.

* * * * *

* * * * *

A little girl was looking at some pictures of ladies in fashionable dresses. While admiring the beautiful styles and bright colors of the garments, she pointed to the waist of one, and exclaimed, "That means trouble." The waist was too small for a grown person, and could only have been made so by tight-lacing. The child had been taught that dresses, corsets, coats, vests, bands, or anything fastened tightly around the waist, press upon the ribs and crowd them out of place, preventing the heart, lungs, and other inside organs from working as they should, causing headache, dyspepsia, shortness of breath, and often ending in some incurable disease, so she knew that tight clothing means trouble to the wearer.

FORMULA FOR THE LESSON ON THE MUSCLES.

1. Muscles are the red, elastic bands and bundles of thread like substance, called flesh, which cover the bones and make the eyeballs, the eyelids, the tongue, the heart, the lungs, and various other parts of the body.

2. There are about four hundred and fifty muscles in my body.

3. The work of the muscles is to support and move my bones, and different parts of the body.

4. The muscles may be named the muscles of my head, the muscles of my trunk, the muscles of my limbs.

5. The muscles of my head cover and move the parts of my head and face. The muscles of my trunk cover and move the parts of my neck and trunk. The muscles of my limbs cover and mote the parts of my arms and legs.

6. Those muscles are the weakest which I use least; those muscles are the strongest which I exercise most in work or play.

7. If I would be strong and healthy, my muscles must be used, my muscles must be rested, my muscles must be supplied with good blood.

I must exercise in work and play to make them strong; I must sleep, or change my kind of work or play, to give them rest, when they are tired; I must breathe pure air, take wholesome food and drink, and live in the sunlight, to supply them with good blood; I must not weaken them by using alcohol or tobacco.

CLASSES AND WORK OF THE MUSCLES.

The muscles are divided into two great classes: those which we may move as we choose, called voluntary muscles, and those over which we have no power, called involuntary muscles.

Some muscles support and move the various parts of the body, others have different work to do. The heart, the great involuntary muscle, acts like an engine to drive the blood throughout the body; the lungs draw in and throw out the air in breathing; the stomach helps to churn and change food into blood; the tongue is used in speaking and eating.

* * * * *

QUESTIONS ON THE SKIN.

Of what use is the skin?—"It covers the muscles of the body."

What can you tell about it?—"It is flexible, elastic, porous, and absorbent."

Why do you say it is flexible?—"Because it is easily bent."

Why do you say it is porous?—"Because it is full of little holes, or pores."

Why do you say it is elastic?—"Because it will spring back after it is stretched, squeezed, twisted, or bent."

Why do you say it is absorbent?—"Because it will soak up liquids."

How many skins have you?—"Two; an outside skin, and an inner skin."

Which is the true skin?—"The inner skin."

Of what is the inner skin composed?—"Of blood-vessels and nerves."

How do you know that the outer skin has no blood-vessels?—"Because if I put a pin through the outer skin the blood does not flow out, as it would if I had cut a blood-vessel."

How do you know the outer skin has no nerves?—"Because if I put a pin through my outer skin it does not make me suffer pain, as it would if I had touched a nerve."

What gives color to the skin?—"A jelly-like substance between the inner and the outer skin."

What have you learned about the true skin?—"That it is of the same color in people of every nation."

What difference is there in the thickness of the outer skin? [See Formula.]

What passes through the pores of the skin? [See Formula.]

What is this waste called when it comes from the surface of the skin?—"Perspiration."

When does the perspiration flow through the pores of the skin?—"All the time, if the skin is healthy."

Why do we not always see the perspiration which passes through the pores?—"Because it does not always form drops on the surface of the skin; it generally passes off in very fine particles."

What becomes of the fine or minute portions of perspiration which pass from the body?—"Some of these portions are absorbed by the clothing; some pass into and mix with the air around us."

What effect does the perspiration produce on the air and the clothing?—"It soon makes the air unfit to be breathed, and the clothing unfit to be worn."

What is necessary if you would have a healthy skin? [See Formula.]

Why must you wear clean clothing?—"That there may be nothing impure in the clothing for the pores of the skin to absorb."

Why should you breathe pure air?—"Because air purifies the blood, and pure blood is necessary to make a healthy skin."

How does drinking alcoholic liquors hurt the skin?—"It makes the blood impure, and impure blood makes unhealthy skin."

In what other way does drinking these liquors hurt the skin?—"It gives the skin too much work to do."

How does it give it too much work to do?—"It makes more waste substance to pass from it through the pores, in the form of perspiration."

In what other way does drinking alcoholic liquors hurt the skin?—"It makes it a bad color."

How does it make the skin a bad color?—"It stretches the little blood-vessels of the skin, and makes them too full of blood." See Appendix.

PART VIII.

FORMULA FOR THE LESSON ON THE HEART AND THE CIRCULATION OF THE BLOOD.

1. My heart is shaped like a cone, and placed in my chest near my breastbone, with its apex pointing downward to my left side. It beats about seventy times a minute, sending out about two ounces of blood at every beat.

2. The blood when pure is of a bright red color; it is a liquid made from food and drink.

3. It passes from my heart to all parts of my body, through pipes called arteries; these arteries spread out through the body like branches from a tree.

4. As the blood flows from the heart, through the arteries, it gives nourishment to every part of the body, and carries away the impurities it meets, which makes it black and thick; when it comes through the veins, back to the heart, it is not fit to be used, so it goes to the lungs to be purified by the fresh air; then it returns to the heart to be sent again throughout the body; this happens once in from three to eight minutes, and is called the circulation of the blood.

7. If I would be healthy, my blood must be pure and circulate freely all the time.

8. It will not circulate freely, if I wear tight clothing, if I do not exercise in work or play, if I do not keep my body warm.

9. It will be impure, if I breathe bad air, if I eat unwholesome food, if I drink alcoholic liquors, if I snuff, smoke, or chew tobacco.

* * * * *

QUESTIONS FOR THE FORMULA.

1. Tell about the heart and where it is placed.

HOW TO TREAT A WOUND.

If it is only a flesh-wound or slight cut, wash it with cold water and bandage it with a clean, white rag. The edges of a deep cut should be drawn together and held in place by narrow strips of adhesive plaster, fastened across the wound from side to side.

If the cut is very deep, and the blood flows very freely, send for a doctor. While you wait for him, knot a handkerchief, or suspender, or towel, in the middle, and twist it very tightly over the cut artery, above the wound. If a vein has been severed, twist the knotted handkerchief below the wound. If the blood continues to flow, tie a bandage both above and below the hurt part.

* * * * *

QUESTIONS ON THE HEART AND THE CIRCULATION OF THE BLOOD.

Of what shape is your heart?—"My heart is shaped like a cone."

Where is it placed?—"In the chest, pointing toward my left side."

What bone is it near?—"It is near my breastbone."

Of what use is the heart?—"It contains the blood and sends it to the different parts of the body."

How much blood is sent from the heart at each beat?—"About two ounces."

What is the blood?—"A liquid made from food and drink."

Of what color is the blood?—"Bright red, when pure; dark red, when impure."

How does the heart send the blood through the body?—"Through pipes called arteries."

What do the arteries resemble in the way they are arranged?—"The branches of a tree."

What makes the blood impure?—"As the blood flows, it gives nourishment to every part of the body; this makes it poor. It also takes up the old worn-out particles; this makes it impure."

Where do the arteries carry the impure blood?—"To the veins."

Where do the veins carry the impure blood?—"To the heart."

Where does the heart carry the impure blood?—"To the lungs."

What happens to the impure blood in the lungs?—"It is made pure."

What makes it pure?—"Pure air."

Where do the lungs send the blood after it is made pure?—"Back to the heart."

Where does the heart send the pure blood?—"Throughout the body."

What is the journey of the blood to and from the heart to the different parts of the body called?—"The circulation of the blood."

What is the circulation of the blood?—"The circulation of the blood is its journey from the heart to the different parts of the body, and from the different parts of the body back to the heart."

How often does this circulation take place?—"Once in from three to eight minutes, according as the heart beats fast or slowly."

What kind of blood is necessary to health?—"Pure blood."

How should the blood circulate?—"Freely, all the time."

What do you mean by freely?—"Without anything to hinder."

What is necessary for the free circulation of the blood?—"I must wear clean clothing; I must exercise in work or play; I must keep my body warm."

How does tight clothing hinder the free circulation of the blood?—"By pressing upon the arteries and veins; and when about the waist, causing the ribs and other parts of the body to press upon the heart."

How does exercise help the free circulation of the blood?—"Exercise makes the heart beat faster, which causes the blood to more faster through the arteries and veins."

Why does keeping the body warm help the circulation of the blood?—"Because the blood moves faster when it is warmest; cold chills the blood, and makes it move slowly."

What harm do alcoholic liquors do to the heart?—"They make it tired, and sometimes wear it out."

In what way do they make it tired?—"They make it beat too fast."

Why does it beat too fast?—"Because it is hurrying to drive the alcohol out of the body."

In what other way do alcoholic liquors hurt the heart?—"They produce disease in it."

Tell one way by which the heart becomes diseased through alcoholic liquors?—"Alcohol softens the fibres of the muscles of the heart, and fills them with fat."

What harm does this do to the heart?—"It makes it too weak to do its work, which is to pump the blood through the body."

What sometimes happens when the heart is thus weakened?—"It stops beating, which causes sudden death."

What harm does alcohol do to the blood?—"It uses up the water of the blood; it destroys the goodness of the red part; it makes the blood thin, impure, and unfit to do its work." See Appendices on Alcohol and Tobacco.

PART IX.

FORMULA FOR THE LESSON ON THE LUNGS AND RESPIRATION.

1. My lungs are the bellows or breathing machines of my body.

2. They are composed of a soft, fleshy substance, full of small air-cells and tubes. They are porous and spongy when healthy, but in some diseases become an almost solid mass, through which the air cannot pass.

3. I breathe by drawing the air through my windpipe, along the tubes into the cells of my lungs, swelling them out, and causing my chest to expand; then the chest contracts, and the impure vapor in my lungs is pressed out through the same tubes, windpipe, nose, and mouth, into the atmosphere.

4. I cannot live without breathing, because if the air does not go down into my lungs, the dark blood in them is not changed into pure red blood, and goes back through my body dark blood, which cannot keep me alive.

5. If I would have healthy lungs, I must breathe pure air, I must live in the sunlight, I must keep my body clean, I must wear loose clothing, I must wear clean clothing, I must sit and stand erect, I must keep all parts of my body warm, I must not change my winter clothing too early in the spring, I must avoid draughts of cool air, I must not rush into the cold when I am in a perspiration, I must not poison my lungs with alcohol or tobacco.

4. Why can you not live without breathing?

5. What is necessary if you would have healthy lungs?

* * * * *

THE AIR AND THE LUNGS.

The air which enters through the nose and mouth passes into a tube of muscles and ring-like pieces of cartilage. The upper part of this tube is the voice-box or larynx, covered by a spoon-shaped lid which closes when we swallow; the lower part is the trachea, and the two parts are the windpipe. The trachea divides into two branches, the bronchial tubes, one for each lung. These tubes divide again and again like the branches of a tree, and end in exceedingly small sacs or bags. The air in these sacs, or air-cells, gives oxygen to the blood in the tiny blood-vessels of the lungs and takes from them the poison, carbonic-acid gas, water, and impurities, which it carries back through the windpipe into the outside air.

* * * * *

QUESTIONS ON THE LUNGS AND RESPIRATION.

Of what are the lungs composed?—"Of a soft, fleshy substance, full of small air-cells and tubes."

Of what use are the lungs?—"They are the breathing machines of the body."

How do the lungs appear when healthy?—"Porous and spongy."

How does the air get into the lungs?—"The air flows through the nose and mouth, into the windpipe and along the air-tubes, into the air-cells of the lungs."

What does the air do in the lungs?—"It swells the lungs and causes the chest to expand."

What do you mean by expand?—"To increase in size."

How is the air expelled from the lungs?—"The chest contracts and sends the impure air through the tubes and windpipe, the nose and mouth, into the atmosphere."

What do you mean by contracts?—"Becomes smaller."

What do you mean by atmosphere?—"The air."

Of what use is the air when it is in the lungs?—"It makes the blood pure."

Why can you not live without breathing?—"Because, if I do not breathe, pure air cannot get into the lungs to make the bad blood pure, and I cannot live if the dark, impure blood is sent back again through my body."

Why must you live in the sunlight?—"Because the sunlight helps to purify the blood and strengthen the body."

Why must you wear loose clothing?—"Because tight clothing stops the circulation of the blood."

Why must you avoid tight-lacing?—"Because tight-lacing crowds the ribs against the lungs, so that the lungs cannot move freely."

Why should you wear clean clothing?—"That nothing impure may pass into the body through the pores of the skin."

Why should you keep the body clean?—"That the pores of the skin may not be closed, but remain open to let the perspiration pass through."

What has the cleanliness of the body to do with the health of the lungs?—"If the body is not kept clean, the perspiratory pores become clogged."

What happens when the perspiratory pores are clogged?—"The impure particles which should pass through them stay in the body, and cause disease in the lungs or other parts."

Why should you sit and stand erect?—"Because, if I am in the habit of stooping, my lungs will be crowded, and will not have enough room to move freely."

Why should you keep all parts of the body warm?—"Because chilling any part of the body causes the blood to chill in that part, and thus hinders its circulation."

Why should you not change your winter clothing too early in the spring of the year?—"I may take cold if not warmly clothed during the cool days of early spring."

Why should you avoid draughts of cool air?—"Because the cool air blows upon some parts of the body and closes the pores of the skin, checking the perspiration, and hindering the circulation of the blood."

Why should you not rush suddenly from a warm to a cool place?—"Because when warm the pores of the skin are open; if I rush suddenly into the cool air, these pores are closed too quickly."

Why does stopping the perspiration hurt the lungs more or less?—"The impurities it ought to carry away remain in the body, make the blood impure, and produce disease in some part; very often that part is the lungs."

What harm does alcohol do in the lungs?—"It fills the lungs with impure blood."

What harm does it do to the air-cells?—"It hardens the walls of the air-cells of the lungs."

What harm is done by the hardening of these air-cells?—"1. The lungs cannot take in enough of the gas called oxygen to purify the blood perfectly. 2. The gases or vapors in the lungs cannot pass freely through the hardened air-cells."

What happens from this?—"The lungs become diseased."

From what disease do some hard drinkers suffer?—"Alcoholic consumption, for which there is no cure." See Appendices on Alcohol and Tobacco.

PART X.

FORMULA FOR THE DIGESTIVE ORGANS AND DIGESTION.

1. When my food is chewed, it is rolled by my tongue into the oesophagus, or food-pipe, which is back of my windpipe, and leads from my mouth down along the side of my spine, to the left and upper end of my stomach.

2. My stomach is an oblong, soft, and fleshy bag, extending from my left to my right side, below my lungs and heart.

3. It is composed of three coats or membranes, and resembles tripe.

4. The outer coat is smooth, thick, and tough. It supports and strengthens the stomach.

5. The middle coat is fibrous. Its fibres have the power of contracting, sometimes pressing upon the food, and sometimes pushing it along toward the opening which leads out of the stomach.

6. The inner coat is soft, thick, spongy, and wrinkled. It prepares a slimy substance and a fluid. The slimy substance prevents the stomach from being irritated by the food. The fluid dissolves the food.

7. Food passes through several changes after it enters the mouth.

8. It is changed into pulp in the mouth, by the action of the teeth and the saliva. This is called mastication. It is changed in the stomach, by the action of the stomach and the gastric juice, into another kind of pulp called chyme. The chyme is changed by the bile and another kind of juice, called pancreatic juice; these separate the nourishing from the waste substance. The nourishing, milk-like substance is called chyle. The waste substance passes from the body. The chyle is poured into a vein behind the collar bone, and passes through the heart to the lungs, where it is changed into blood.

9. If I would have a healthy stomach, I must be careful what kind of food I eat, I must be careful how much I eat, I must be careful how I eat, I must be careful when I eat.

10. I must eat wholesome food, good bread, ripe fruits, rather than rich pies or jellies.

11. I must eat enough food, but not too much.

12. I must eat slowly, I must masticate my food thoroughly, I must masticate and swallow ray food without drinking

13. I must take my food regularly but not too often, I must rest before and after eating, if possible, I must not eat just before bedtime.

14. I must breathe pure air, I must sit, stand, and walk erect, I must not drink alcoholic liquors, I must not snuff, smoke, or chew tobacco.

* * * * *

"EAT TO LIVE, NOT LIVE TO EAT."

There is pleasure in eating, because God has given us the sense of taste, that we may enjoy our food. But not everything which pleases this sense is good for the body, so we should learn what things are wholesome and choose them for our food and drink, refusing everything which is unwholesome. Those who obey these rules "eat to live" and never become drunkards or gluttons.

What do you mean by fibrous?—"Composed of threads."

What do you mean by fibres?—"Threads."

Of what are the fibres of the stomach composed?—"Of flesh."

Of what use are the fibres of the stomach?—"They press upon the food, and push it toward the opening which leads out of the stomach."

Describe the inner coat of the stomach.—"The inner coat is soft, thick, spongy, and wrinkled."

Of what use is the inner coat of the stomach?—"It prepares a slimy substance and a fluid."

Of what use is the slimy substance?—"It prevents the stomach from being irritated by the food."

Why should you breathe pure air?—"Because pure air helps to make pure blood, which the stomach needs to make it strong and healthy."

Why should you sit, stand, and walk erect?—"That the stomach may not be crowded out of its place, or pressed upon by other parts of the body."

In what way does tobacco hurt the stomach?—"It poisons the saliva and prevents it from preparing the food to enter the stomach."

What harm does tobacco do inside the stomach?—"It weakens the stomach and makes it unfit to change the food into chyme."

How will wise children treat tobacco?—"Let it alone. They will not chew, snuff, or smoke the vile weed."

Is alcohol food or poison?—"It is poison."

How do we know it is not food?—"Because it cannot be changed into blood."

How has this been proved?—"Alcohol has been found in the brain, and other parts of drunkards, with the same smell and the same power to burn easily which it had when it was taken into the mouth."

How do you know it is a poison?—"Because it does harm to every part of the body, beginning in the stomach."

What harm does alcohol do in the stomach?—"It hinders the stomach from doing its work; it burns the coats of the stomach; it destroys the gastric juice; it hardens the food, so that it cannot be dissolved by the gastric juice."

What does the stomach do with alcohol?—"Drives it out as soon as possible."

Where does the stomach send it?—"Into the liver."

Where does the liver send it?—"To the heart; and the heart sends it to the lungs."

What do the lungs do with the alcohol?—"They drive it out as soon as they can."

Where do the lungs send some of it?—"Through the nose and mouth, into the air."

What harm does the alcohol do in the breath?—"It poisons the air; it tells that some kind of alcoholic liquor has been taken into the stomach."

From what you have learned about alcohol, what do you think is the only safe rule to obey concerning cider, beer, wine, and all alcoholic liquors?—"I must not drink them, if I wish to have a strong and healthy stomach."

PART XI.

FORMULA FOR THE LESSON ON THE NERVOUS SYSTEM.

1. My brain is a soft gray-and-white mass resembling marrow.

2. It is placed in a bony box called the skull; it is covered and held together by three coats or membranes.

3. The outer membrane is thick and firm; it strengthens and supports the brain.

4. The middle membrane is thick, and somewhat like a spider's web in appearance.

5. The inner membrane is a network of blood-vessels.

6. From the brain, white or reddish gray pulpy cords, called nerves, pass to all parts of the body. These nerves are of two kinds: nerves of feeling, and nerves of motion.

7. If I prick my finger, a nerve of feeling carries the message to my brain; if I wish to move my finger, a nerve of motion causes my finger to obey my will.

8. Twelve pairs of nerves pass from the base of the brain: the first pair, called the nerves of smell, to my nose; the fourth pair, called the nerves of sight, to my eyes; the fifth pair, called the nerves of taste, to my mouth, tongue, and teeth. One pair pass to my face; another to my ears. The ninth, tenth, eleventh, and twelfth pairs to my tongue and parts of my throat and neck.[3]

9. The spinal cord is a bundle of nerves extending from the base of my brain, down through the whole length of my spine, or backbone. It is the largest nerve in my body.

10. From the spine, thirty-one pairs of nerves, called spinal nerves, pass to different parts of my body; some to the lungs, some to the heart, some to the stomach, some to the bones, and some to the muscles and skin.

11. If a nerve be destroyed it cannot carry messages to and from the brain. Before filling a tooth, the dentist sometimes destroys its nerve.

12. If a nerve be pressed upon too long it cannot perform its duty. If I press upon the nerve passing to my foot, I stop it from communicating with the brain; the foot loses its feeling, or, as I say, "is asleep."

13. If I drink alcoholic liquors, or snuff, smoke, or chew tobacco, my brain and nerves cannot do their work well; because alcohol and nicotine are very poisonous to the brain and nerves.

14. The brain must be supplied with good blood;

The brain must be used;

The brain must be rested;

I must drink wholesome drink, eat wholesome food, take enough exercise, and breathe pure air, that my brain may be supplied with pure blood;

I must study and think, that my brain may grow and be strong for work;

I must rest my brain when it is tired, either by changing my employment, or by going to sleep;

I must not poison my brain with alcohol or tobacco.

[3] NOTE.—A fuller description of the Nerves of the Brain: Twelve pairs of nerves pass from the base of the brain; the first pair, called the nerves of smell, to my nose; the second pair, called the nerves of sight, to my eyes; the third, fourth, and sixth pairs to the muscles of my eyes; the fifth pair to my forehead, eyes, nose, ears, tongue, teeth, and different parts of my face; the seventh pair to different parts of my face; the eighth pair, called the nerves of hearing, to the inner part of my ear; the ninth pair to my mouth, tongue, and throat; the twelfth pair to my tongue; the eleventh pair to my neck; the tenth pair to my neck, throat, lungs, stomach, and different parts of my body.

THE BRAIN AND ITS WORK.

The brain is egg-shaped, and of two parts, the large brain (cerebrum), and the little brain (cerebellum). These are composed of a white and gray substance, which in the large brain is so folded and wrinkled that it looks like the meat of an English walnut; in the little brain it is so arranged that it resembles a tree, and is called arbor vitae, tree of life. The mind does its thinking through the large brain, and controls its muscles through the little brain.

A drunken man can not walk straight because alcohol has hurt the little brain; he can not think straight because it has poisoned the large brain.

ALCOHOL.

THE STORY ABOUT ALCOHOL.

Several hundred years ago many people were trying to discover something that would keep them young and strong, and prevent them from dying. It is said by some that a man named Paracelsus, in making experiments, discovered alcohol. He called it "the water of life," and boasted that he would never be weak and never die; so he went on drinking alcoholic liquors until at last he died in a drunken fit.

What is this alcohol which has done and is doing so much mischief in the world? I will show you some. What does it look like?—"Water." Yes; and if you were to smell it you would say it has a somewhat pleasant odor; if you were to taste it, that it has a hot, biting taste, i.e., is pungent. If you put a lighted match to it you would notice that it burns easily, and with a flame, and may therefore be said to be combustible and inflammable.

What does it come from? Is it one of the drinks God has given us? Some of the class think it is; we will try to learn whether this answer is correct or not. If we study about it very carefully we shall discover that it is not a natural drink, that it is not found except where it has been made from decayed or rotten fruits, grains, or vegetables.

If you take some apples, and squeeze the juice out of them, you will find it sweet and pleasant; let that juice stand for several days and what will happen to it?—"It will get bad." Yes; or, as grown people say, it will work or ferment; that is, the sugary part of the juice will be separated into a kind of gas and a liquid. The gas is called carbonic acid gas; the liquid is alcohol. Both the gas and the liquid are poisonous.

Alcohol may also be obtained from other fruits, as grapes, and from some grains and vegetables. But all these must first become rotten before alcohol will come out of them. This is one reason why we think that God, who gives us good, wholesome food, did not intend alcohol to be a drink for man, else He would have put it into the delicious ripe fruit, and not made it impossible to get until they decay.

Now let us put upon the blackboard something which will help us remember what we have learned about

ALCOHOL. DISCOVERED BY DESCRIPTION. MADE FROM Paracelsus. Water-like; with a Fruits, Grains, or pleasant odor; a Vegetables. CALLED hot, biting taste; "The water of life." and will burn with a flame.

USES OF ALCOHOL.

We put some sugar into water; the children see that it melts; then some glue or shellac is placed in the same liquid; they see that this is not melted, but that, when alcohol is used instead of water, the glue or shellac is dissolved. From this experiment they learn that alcohol is used in making varnishes.

Some water is poured into one saucer, and alcohol into another; a lighted match is applied to each; the class notices that the alcohol takes fire and burns, while the water does not.

Next, we fill a lamp with alcohol, and put a wick into it; when the wick becomes wet with the fluid it burns steadily and without smoke, as may be seen by holding a clean white saucer over the flame. This shows why jewellers and others, who wish to use a lamp to make things very hot, prefer alcohol to kerosene, which, as the children know, smokes lamp-chimneys, or anything else, so easily.

We show a thermometer; the children are told its use if they are not already familiar with the instrument; we talk about the quicksilver in the tube, about its rising or falling according to the degree of heat or cold; then we inform the class that in some countries where it is very cold quicksilver freezes; for this reason alcohol, which does not freeze, is colored red and put into the thermometer tube to be used in these Arctic regions.

Another use for alcohol is to keep or preserve substances. This we illustrate by placing a piece of meat into some alcohol. We explain that the water in the meat is that which causes it to decay. Alcohol has the power to take up or absorb water; so when meat is put into this liquid the water from the meat is absorbed by it, and the meat does not become bad. Those who wish to preserve insects a long time, and doctors who desire to keep any portion of a human body after death, put these into alcohol, in which they may be kept for a long time.

Lastly, we let the children smell cologne or other perfumery, and tell them this is made from different oils mixed with alcohol.

At the close of this lesson the class is ready to help us make the following BLACKBOARD OUTLINE.

FACTS ABOUT ALCOHOL. GOOD USES OF ALCOHOL. It melts gums. To melt gums. Burns with a flame. To make varnishes. Burns without smoke. To burn in lamps. Will not freeze.

USES OF ALCOHOL—concluded.

You see alcohol is very useful for some purposes; but do people ever drink it? Some of the children think not, and we grant that no one is foolish enough to drink raw alcohol, because it is too strong. It would take only a little to make them drunk, and only a few ounces to kill them instantly.

We ask the pupils if they have ever seen a drunken person, and what made that person drunk? We soon obtain an answer, and place upon the board "Rum, gin, whiskey, brandy," as the names of drinks which will take away the good sense of those who drink them. To these are added "Wine, beer, ale, lager, and cider."

We explain that all these have alcohol in them, as may be known by smelling them, or by smelling the breath of those who have drunk even a little of them; and that because they contain alcohol they are called alcoholic liquors. If a person drinks any one of them he will be poisoned, more or less, according to how much he takes. The children are astonished at the word poisoned, but we explain that the very word, intoxicated, means poisoned. So a drunken man is a poisoned man. If enough alcohol, or alcoholic liquor, is drunk by anyone, he will drop down dead as quickly as if he were shot by a cannon ball.

When told that alcohol is not a food, but a poison, the class readily understands what we mean, and we have no difficulty in having the following statements prepared and memorized:

ABOUT FERMENTATION AND FERMENTED LIQUOR.

ALCOHOL.—Alcohol may be obtained from any substance which contains sugar or starch, or both sugar and starch, as apples, pears, grapes, potatoes, beets, rice, barley, maple, honey, etc.

Alcohol can be obtained only by fermentation. By fermentation we mean the change which takes place when a juice containing sugar decays, or goes to pieces. You know decay always makes things fall to pieces.

You ask, what pieces is sugar made of? Very, very little pieces, called atoms. There are different kinds of sugar. In that made from grapes, called grape sugar, there are six atoms of carbon, twelve of hydrogen, and six of oxygen. What are carbon, hydrogen, and oxygen? Oxygen is the kind of gas which keeps animals alive, and makes things burn. Hydrogen is another kind, which you have smelled perhaps when water has been spilled on a hot stove; the gas burned in street-lamps is hydrogen that has been driven out of coal. Carbon you see in charcoal and soot; the black lead of your lead-pencils is mostly composed of carbon and iron; lamp-black is pure carbon, without form or shape.

We will let these circles of colored paper stand for the atoms of carbon, hydrogen, and oxygen in grape sugar,—the largest, which are red, for the oxygen; the second size, which you notice are black, will represent atoms of carbon; while the little blue ones will make you think of hydrogen.

If you remember that it takes one atom of carbon and two of oxygen to make carbonic acid gas; also, that two atoms of carbon, one of oxygen, and six of hydrogen to form alcohol, you can easily find that two atoms of carbonic acid gas and two atoms of alcohol may be formed from an atom of sugar. So the more sugar a juice contains the more alcohol may be formed from it.

CIDER.—Cider is made by pressing the juice out of apples. This sweet cider ferments, and the sugar part of it changes into carbonic acid gas and alcohol. People who do not understand this go on drinking cider, not knowing that it makes drunkards of those who drink much of a beverage which seems so pleasant and harmless.

WINES.—Wines are made from the juices of fruits which have sugar in them, especially grapes. Sometimes people have what they call home-made wines, which they make from blackberries, currants, elderberries, gooseberries, cherries, or other fruits. They may ask you to take some, saying, "This will do you no harm; we did not put any alcohol into it." They do not know what you have learned, that alcohol is always formed in fermented juices which contain sugar. It does not wait to be put into the home-made wines; it quietly comes in as they are getting made, at home or any other place, and will make people drunk as surely as when it is found in brandy or any other liquor.

Some of the wines in the stores are made from grape juice, but many more are made by mixing hurtful and poisonous things together to make the liquor strong, and give it what is called a fine color and good taste.

BEER AND ALES.—These are made from grains and hops, which contain no sugar, it is true, but are composed of starch, which may be changed into sugar. When a seed of grain is put into the ground and begins to grow, the starch in it becomes sugar, which feeds the young plant. When a brewer wishes to make beer, he takes some grain, puts it in a dark place, wets it, and leaves it to sprout, or begin to grow. Then he puts it into an oven to dry it, and make it stop growing. This makes what is called malt. The malt is mashed and soaked in warm water to get the sugar out of it; this forms a liquid called sweet wort. The wort is separated from the mashed grain and boiled; yeast is mixed with it to help it to ferment more quickly; it soon becomes changed; a dirty yellow scum filled with bubbles comes to the top, which we know is the poisonous carbonic acid gas; the other poison, alcohol, stays in the liquid and makes the beer taste good to those who like it.

Liquors made from grain are called malt liquors. Lager beer, and all kinds of ales and porters, are malt liquors. They make people dull, sluggish, and stupid who drink much of them. They do much mischief in the body, though it takes a larger quantity of any one of them to make a person drunk than it does of whiskey or brandy.

* * * * *

DISTILLATION.

How does the sugar in grapes and other fruits become alcohol?—"By fermenting." Yes, and liquors made by fermenting are called fermented liquors. What other alcoholic drinks have you heard about beside cider, wines, beer, and ales?—"Gin, whiskey, brandy, rum." These are stronger than the fermented liquors, that is, they contain more alcohol; they are made by what is called distillation.

If you boil water, and let the steam from it fall upon a cold plate, the steam will change back into liquid and become distilled water. Making a liquid boil, catching the vapor or steam and cooling it, is what we mean by distillation.

If two or more liquids are mixed together, the one that boils with the least heat will be drawn off first. The alcohol of beer, cider, and wines is mixed with water; it boils at a lower heat than water, so can be drawn off from it very easily. This does not make more alcohol, it only makes the alcohol stronger by separating it from the water.

When beer or any other alcoholic liquor is to be distilled, it is poured into a large copper boiler, called a still, and boiled. A tube carries the vapor from the boiler into a cask filled with cold water. This tube is coiled like a spiral line or worm through the cask; it is called the worm of the still, and the cask is the worm-tub. As the vapor passes through the tube, it cools and drops out at the end into the worm-tub, changed into a liquid stronger in alcohol than that from which it was drawn or distilled.

In this way gin is made from beer, brandy from wine, and rum from fermented molasses. These are very strong drinks, and only hard drinkers like them. But very few people begin by taking these; they first learn to like alcohol by drinking cider, beer, or wine, and end with gin, whiskey, or rum when they have become drunkards.

HARM DONE BY ALCOHOL IN VARIOUS PARTS OF THE BODY.

Raw alcohol does not do much harm to people because it is too strong for them to drink much of it; but the alcohol hidden in cider, ale, wine, whiskey, and other alcoholic drinks kills not less than sixty thousand persons in this country every year, besides those who die from its use in other parts of the world.

There is great excitement when there is a mad dog around; and, if any one is bitten and dies from the dreadful hydrophobia, people are ready to destroy all the dogs of the neighborhood; but when a drunkard dies from delirium tremens or alcohol craziness, how few take any notice of the cause of his death, or do all they can to wage war against the use of alcoholic liquors.

But why do we say such hard things against these liquors which some people love so well and think so harmless? In what way do they hurt and kill people? Let us see. Where does what we drink go after it has been put into the mouth?—"Into the stomach." If it were the right thing to go into the stomach, into what would it be changed?—"Into something which helps to make good blood."

Learned men, who have examined and carefully studied about these things, tell us that the stomach is hurt by alcohol, because the fiery fluid is not food, but poison which makes the stomach very sore, and gives it hard work to do. The veins of the stomach take it up and send it into the liver. The liver, which is a large organ weighing about four pounds, lies on the right side below the lungs; its work is, to help make the blood pure. It can do nothing with alcohol, so it drives it along to the heart; the heart sends it to the lungs; the lungs throw some of it out through the breath, which smells of the vile stuff that has been poisoning every part it has passed through since it entered the mouth.

Some of the alcohol does not get out of the lungs through the breath, but goes with the blood back to the heart, and from the heart is sent through the arteries to every part of the body. No part of the body wants it.

The Skin drives some of it out, through its little pores, with the perspiration.

The Kidneys, which lie in the back below the waist, on each side of the spine, send off some of the poison.

Yet some of it gets into the brain, and there does very much mischief, of which you will learn more by and by. You know, if the brain is hurt, the mind cannot do its work of thinking properly; thus, alcohol does great harm to the mind through the brain.

The muscles and the bones are hurt by not being supplied with pure blood; the heart gets tired out with overwork, and the lungs become diseased through this same terrible alcohol.

Therefore, if you would be strong and healthy, have nothing to do with alcoholic liquors; for

ALCOHOL POISONS The stomach, The liver, The blood, The heart, The lungs, The brain, The bones, The muscles, The skin, And every part of the body.

IN THE STOMACH.

Children who have learned the Lesson on Digestion, and know about the coats of the stomach, about mastication and chyme-making, are easily made to understand why anything which has alcohol in it is unfit to go into the stomach.

If we touch a drop of alcohol to the eye, it will make it sore; so alcohol in the stomach irritates its coats and makes them sore.
