=Some things hasten puberty.=--There are some things that will hasten puberty. Several thousand miles South, puberty comes on a boy a few months sooner than it does here. Several thousand miles North, puberty comes later than here. Thus we see that a warm climate tends to hasten the arrival of puberty, and a cold climate will tend to retard it. This is the main reason why puberty, in the colored race, comes a few months sooner than it does in the white race. For centuries the negro lived in the hot climates of Africa. In this country he has lived largely in the South. Vulgar language, impure thoughts and the cigarette habit will tend to hasten puberty. These bad habits arouse passion and lead to the formation of semen before the body is prepared to absorb it. This leads to the habit of wasting this energy from the body. It will be noticed by you that the cigarette smoking and vulgar boys grow up to have a pale or a dark complexion and many are stunted and ugly. Using cigarettes before you are fifteen will do you more harm than to use them after that age. =The nature and value of the creative life.=--The wisest doctors tell us that one drop of semen is worth twenty drops of blood; one ounce is worth twenty ounces of the purest blood. If a discharge of this energy were taken from the body of a healthy, strong man, twenty-five years old, and placed in a small glass test-tube and allowed to settle for ten hours, it would divide itself into two unequal parts. The upper and smaller portion would be thin, clear and slightly oily. It would look just like joint water. The lower and larger portion would be thick and milkish in color, with many little (16) sperm cells. These cells can be seen only under the microscope. They are in the shape of a tadpole, except they are longer in proportion. They are very active at first, but when the fluid becomes chilled they soon die. They are formed from the blood and contain life. =The condition of an unwell man.=--If a discharge is removed from a man that is in poor health, a man who drinks liquor, uses much tobacco, or wastes this energy from his body, it will be found that the amount, as a rule, is much smaller, the parts reversed, sperm cells fewer in number, smaller in size, slower in movements, than in the discharge taken from a healthy man. This illustration shows how bad habits injure the blood and rob a man of his energy.
