The names of these organs are pure.—Unfortunately, almost all boys have received their first information about sex from the vicious. Such teachers are ignorant for they do not know the true names of these organs or their true purposes. They are vicious because their teaching is largely false and they fill the minds of boys with impure thoughts and ideas. Let twenty boys write down on paper all the names of their sexual organs that they have ever learned and not less than thirty names would be found among them. Now go to the dictionary and look for these names. One out of every five cannot be found, for the reason that it is not a part of our language. The other words do not, even remotely, refer in meaning to the sexual organs. This is a sample of the ignorance of such men and boys who are always ready to tell a boy something that he is not to tell his parents. Such teaching is a very great evil. It has poisoned the minds and hearts of thousands of boys and started them on the road to ruin. It is very important that you fix the thought in your mind that these organs are as pure as any other organ in the body and that their names are just as pure as any other word in the language. There are many reasons why we should not expose these organs or talk about them, except when it is right or necessary for us to do so. We should learn all we can about our lungs, hearts, brains and other organs of the body. When we can see these organs or pictures of them, they help to make many things plain to us that would be difficult for us to understand. For this reason we have placed the cut of a boy’s body in this book, showing the urinary and sexual organs.

The urinary organs.—The urinary system consists of the following organs: Two (1) kidneys, only one can be shown in the cut. The kidneys are located just above the small of the back and in front of the spinal column, or backbone. The kidneys take up water, waste matter and impurities from the blood. In this way the kidneys help to keep the blood pure. This liquid mixture is called urine. The use of tobacco and strong drink injures the kidneys, and prevents them from doing all the work that they need to do in order to keep the blood pure and the body healthy and strong. As fast as the kidneys form the urine it is carried by two ducts, called the (2) ureters, one leading from each kidney, and emptied into the (3) bladder. Here it is stored until we wish to discharge it from our bodies. The urine is discharged from the body by a duct that leads through the external sexual organ, and this duct is called the (4) urethra. This process of discharging the urine is called urinating. This is a perfectly natural act. There is no more sin in urinating than in shedding a tear. Because of unfortunate training, many boys think of this act as sinful. The words and expressions they have learned for this act have been associated for years with low thoughts. It is for this reason that you should cease to use those false words and expressions and learn to say, “I desire to urinate,” or “I have urinated.”

The sexual organs.—Some of the sexual organs are on the outside of the body and some are on the inside of the body. Those on the outside of the body are perfectly familiar to all boys. The external organ through which the (4) urethra passes is called the (5) penis. This organ is not shown in the cut, its position being shown by the figure (5). At the end of this organ is a sheath of loose skin, called the prepuce or foreskin. In some boys the prepuce is quite long and tight. When the boys of the Jewish race are eight days old they are circumcised. This act consists in cutting off that portion of the prepuce that extends beyond the head of the penis. The act is performed with a sharp knife and causes but little pain. Ninety millions of Mohammedans practice circumcision. This



should be performed on many boys in this country when they are only a few days old. There are a number of reasons for this. Underneath the folds of the prepuce are hundreds of little glands that secrete a substance that should be removed daily with water, or a wet rag. When the prepuce will not glide back over the head of the penis, it cannot be kept clean. In such cases the secretion becomes white and hard and causes irritation. Boys in this condition will often scratch this organ. In many cases, these boys do not get along well in school, they are nervous, have fits and spasms, and this scratching often leads to a bad habit.

When the prepuce of a boy will not glide back, becomes red, sore and swollen, he should ask his father to have a doctor treat him. The doctor will know how to enlarge the opening, break up the adhesion and glide it back.

Underneath the penis is a sack, called the (6) scrotum, in which are suspended two glands, called the (7) testicles. The (7) indicates where these glands would be if placed in the cut. Leading off from the (8) descending artery are two small arteries, called the (9) spermatic arteries. They carry pure blood to the testicles. Leading back from the testicles are two small veins that separate from the spermatic arteries and are called the (10) spermatic veins.
