Another side to the problem of the young woman's relation to love and marriage is brought to our attention by the lamentable fact that many wives lose interest in devoted husbands when the children come. This is probably true in at least half the families; and many matrimonial disharmonies are the result. This is really one of the greatest problems of marriage which cultured women should consider seriously; for even more than in most other sex problems, it is one for the solution of which women are in a position to take the leading part. This problem is especially important in these days when the household inefficiency, personal extravagance, and desire for social position of numerous young women of eighteen to thirty are having an enormous influence in advancing the age of marriage because many of the best types of young men pause and consider seriously the impossibility of adjusting a small salary to the ideas of their women friends as to what is the minimum of a family budget. Add to such facts a growing pessimism of young men regarding inconstant affections of wives with children, and the need of special educational attack is evident. [Sidenote: The duty of parents.] From whatever side we look at the question whether the larger sex-education should somehow try to mold the ideals of young women with regard to love and marriage, we see reasons why parents should encourage their maturing daughters to get some advance understanding of such relation. If parents are themselves unable to help their daughters to this understanding, they can at least exert great influence by their own attitude, and they can approve the reading of books, and perhaps there may be opportunity for hearing lectures by women who understand life. [Sidenote: Books.] With regard to good literature that will help in this line, there are chapters in many of the books mentioned at the end of this lecture, and in more or less indirect form in the general literature suggested in the preceding lectures concerning young men, and in Sec. 12 which deals with the general educational problem of marriage.
