The question, at what ages we shall advise our young couple to have children, is a separate one, depending upon many circumstances. First, of course, they should not have any until they are able financially to maintain them. As to the age at which it is physically advisable, that is a question to be settled by physicians and physiologists. I myself had the idea that the proper age would be when the woman had attained her full stature; but my friend Dr. William J. Robinson sends me some statistics from the Johns Hopkins Hospital _Bulletin_, which startle me. This publication for January, 1922, gives the results in five hundred childbirths, in which the mother's age was from twelve to sixteen years inclusive. It appears that pregnancy and labor at these ages are no more dangerous than in older women; but on the other hand, the duration of the labor is actually shorter, and the size of the children is not inferior. These facts are so contrary to the general impression that I content myself with calling attention to them, and leave the commenting to be done by feminists and others who oppose themselves to the idea of early marriage. CHAPTER XLI THE MARRIAGE CLUB (Discusses how parents and elders may help the young to avoid unhappy marriages.) I will make the assumption that you would like to have a trial of my cure for prostitution. You would like to do something right here and now, without waiting for the social revolution. Very well: I propose that you shall find a few other parents of boys and girls who are in revolt against our system of hidden vice, and that you will meet and form a modern marriage club. Only you won't call it that, of course; you will tactfully describe it as a literary society, or a social circle, or an Epworth League. The parents who run it will know what it is for, just as they do today; the only difference being that it will exist to promote love matches instead of money matches. It happens that I am myself a tactless sort of a person, not skillful at avoiding saying what I mean. So, in this chapter, I shall content myself with setting forth exactly what this marriage club will do, and leaving it to more clever people to supply the necessary camouflage.
