HUMAN SELECTION.--Under the head of human selection Galton and Wallace have made some interesting and valuable suggestions for improving the health and quality of man. Mr. Galton proposed a system of marks for family health, intellect and morals, and those members of families having the highest number were to be encouraged to marry early by state endowments sufficient to enable them to make a good start in life, early marriages being favorable to large families. It was a bold suggestion, savoring too strongly of socialism or state control of marriage to suit many of us. Professor Wallace's plan is that women shall, so far as possible, be made independent, so that they will not feel the necessity of marrying for a home. Her time might be occupied either in public duties or self-culture, or any occupation she might prefer. She should be educated to believe it degrading to marry for a home, without love and adaptation, and equally wrong to marry her inferior. This would compel men to be more manly, to leave off their bad habits and many vices, in order to obtain wives; and the idle, selfish, sickly and deformed would not easily get them. One difficulty in the way of carrying out this plan is the greater number of women in society as it exists today, owing to the larger mortality among boys. But by a better hygiene which is likely to result from the evolution of the race, this greater mortality of the masculine sex is certain in the future to be prevented, and there will then be an excess of men instead of women. This will be a real advantage, for a scarcity of women would give her a greater influence in selection, and the result would be, the worst men would not be able to get wives. Being in a minority, women would be held in higher esteem, be more sought for, and have a real choice in marriage by being able to reject unsatisfactory suitors, which is certainly not the case now to any considerable extent. Mr. Wallace's plan would not require such early marriages as that of Mr. Galton's, and this would be a positive benefit to the physical vigor of the children, for we know that the progeny of too early marriages are more delicate, and reproduction before bodily maturity lowers the standard of health in parents as well as of their offspring. Marriage being delayed, and the culture of the mind being more attended to than is possible when it is early, would reduce the number of children in any family, and this would enable parents to bestow more care upon them. It would also prevent, to a limited extent, over-multiplication of the race, which is a real evil, for if every couple left three or four children the whole world would soon be full, and over-population would result in much disease.
