The sympathetic nervous system, or sympathetic nerves, link the body together in harmonious action. It guards one part of the system from acting detrimentally against another. It is the principal influence in controlling the circulation, nutrition, digestion, and assimilation. All involuntary organs are governed by this system of nerves, so that when the brain is asleep the work that is vitally essential to our existence will go on correctly.

Hygiene is a body of facts or principles that are essential to the preservation of our bodies, health and happiness. I shall abridge my sentences in speaking of this subject. In the first place a man should be regular in his habits: that is, have regular hours for sleep, regular hours for meals, three meals per day when laboring, six hours apart, and should never retire to rest until two hours after supper. Should not drink anything while eating, so that the saliva, Nature's fluid may mingle properly with the food, that it may be digested readily and properly. Persons should chew their food so fine before swallowing that they can feel no lumps in it with the tongue, in order that the gastric juice may readily penetrate and digest it.

The room or place a person sleeps in should be well ventilated, so that the air is pure and refreshing, which gives life and activity to the entire body; and he should bathe twice per week, in order that the skin may be kept pure and clean, that it may not reabsorb the poisons that are thrown out form the pores. The water should only be a few degrees above the temperature of the body. The body should be well rubbed after bathing with a rough towel till the skin is glowing. This calls the blood to the surface and promotes a healthy circulation, and makes a person feel better every way. The clothing should be changed once every week, because they become saturated with the fumes and odors of the body, which, if reabsorbed, are poisonous to the general system. Cleanliness is next to godliness, and beyond question or doubt, is the key note of man's health. Every one, when eating, should stop before they realize the sensation that they have got enough. Franklin says: "If you would have an appetite stop with one." And it is true. Knick knacks, if eaten at all, should be eaten before substantial food, because when they are left till the last, you have already eaten all the necessary food that you need, and then come dainties that tickle the appetite and cause you to eat more than is demanded by nature, and the result is indigestion or dyspepsia. Everybody needs exercise in order that they may have proper development of the bodies they own. No one should work in a room where it is dark, for darkness is a sedative, and light is a stimulant, to the animal organization as well as the vegetable. Take a man and let him work in a dark cellar, and the result is he soon becomes pale and poor in flesh. Take a plant and set it in the shade, and it becomes a pale green, slim, tall, and spindling; hence, my readers, you see the importance of good light. In concluding my remarks on hygiene, I will say that it is strictly important, in order that we may have good health, we should have good light, good air, good food, good water, sufficient clothing, strict cleanliness, and discretion and temperance in all things. All persons observing these rules will seldom be obliged to call the physician to administer unto him in a case of sickness, unless of a contagious character.
