Lecturing to nearly one hundred thousand young men a year and having several thousand a year to interview me, in this way the conclusion from my correspondence is confirmed. When a boy is fourteen he should be given a more complete talk on the nature and effects of the secret sin. If he is found to be guilty he should be induced to break off. If his sexual desire is due to a tight prepuce, this should be treated by the family physician. If due to a tight frenulum, this requires the attention of a doctor. As a rule his sexual excitement grows out of a mind that has been filled with lascivious thoughts from some schoolmate or servant. This can be corrected by satisfying the boy’s morbid curiosity with the truth and a faithful warning of the dangers of this vice. =Fathers should not be suspicious but watchful.=--A wise father will have a frank, positive understanding with every servant in the home and employee on the farm, or in his business, that he is not to encourage vice by vulgar conversation, vicious practice, or by presenting the child with a vile book or showing him a lude picture. Keep an eye on the little visitors--and the big ones too. There are in circulation some most inconceivable immoral books that teach children every phase of sex perversion. I recently secured such a book and it was estimated by the school board that two hundred or more boys from twelve to sixteen had read it. Only a few months ago the president of a female college living in the girls’ dormitory told me of how one of the college girls had introduced his three-year-old boy to the vice. About the same time and in the same State, an editor said to me, “Professor, you don’t realize the temptations to which the small Southern boy is exposed in his relation to the colored help about the home.” A wise father will be on the guard from the time his boy has quit the cradle until he has passed safely through the stormy period of adolescence. CHAPTER XXI FATHER’S FIRST TALK--BOYS MAKE MEN Trees are grown-up sprouts; dogs are grown-up pups; horses are grown-up colts; and men are grown-up boys. A crooked, scarred sprout will produce an ugly, useless tree; a starved, neglected and abused pup will grow up to be a cowardly or vicious dog; a spoiled colt will make a vicious horse; boys who are not trained to work, study and be moral will grow up to be lazy, stupid and bad.
