The talk about the science of mating the horses he will understand readily and thoroughly, and he will not fail to see the point when you switch to man and apply the same principles. Then when you show how mismating is responsible for poor children quality and how disease accounts for feeble-minded and degenerate offspring, he will be fairly well posted, and he will be ready to imbibe more details, and you will have done much of your duty. His curiosity will be quickened and his interest is awakened. It depends upon the father. If your boy is honest and clean, open and decent, he will not fall without a fight, and while he is fighting he is maturing. If your picture of the consequences of the venereal diseases has been effective and vivid, he will grow up with a healthy horror of them. If your conduct as a father has been wise and exemplary, and if your home has the right kind of environment, and the right kind of mother in it, you have done all a father can do to help the boy over the rough spots. The proper kind of encouragement and the right kind of vigilance, and books which will satisfy the boy's craving for more knowledge along this line is all that is needed to help the boy to "win out." FAKE MEDICAL TREATMENT FOR VENEREAL DISEASES.--Parents should in every possible way discourage the use of patent medicines and fake medical methods of curing these diseases. Untold harm has been done to boys and to women by these nostrums. In every instance the motive underlying the methods of people selling these things is to frighten the patients into the belief that their condition is more serious than it is in order to justify a long and expensive course of treatment. Their work is carelessly performed, and frequently they are directly responsible for the development of complication and dangerous sequelae. The promises of speedy cures are false, and, not infrequently, methods of black-mailing have been known to follow an expensive and unsuccessful course of treatment. There is no class of disease in which the help and honesty of the legitimate medical profession is needed more than in the treatment of the venereal diseases. Parents should see to it that the family physician is prescribing any strange medicine that may appear in the boy's room, and not some unknown individual who may be an impostor and a blackmailer. SOWING WILD OATS.--Writers of fiction and others of a more serious trend of thought have recognized the sowing of wild oats as an institution which, if it does not merit the full approval of society's moral code, is, at least, tolerated. No serious consequences befall the offender. On the contrary, the libertine is the type of hero who receives the commendatory quips of erotic dames and the questionable interest of hysterical maidens.
