[Footnote 4: Dr. Karl Pearson, of London, the well-known authority on eugenics, has investigated rather carefully the health of children in large and small families, and has demonstrated that children are healthiest when there are five to eight children in the family. On the average, first and second children are not as healthy as those who come later in the family, and those who are in the best condition physically and mentally for life come after the fourth. The early children in the family are more liable to epilepsy and certain serious nervous diseases, and are often of unstable nervous equilibrium, while the later children are more gifted and are likely to live longer.] The sacrifices of social pleasures and of passing ease and comfort in order to bear and raise four or more children in the family are, as a rule of nature, amply rewarded in the health and strength of both the children and the mother. In my book on "Health through Will Power", in the chapter on Feminine Ills and the Will, I have pointed out that in spite of the tradition which assumes that a woman's health is hurt if she has more than {78} two or three children, the women of the older time, when families were larger, were healthier on the average than they are now, in spite of all the progress that medicine and surgery have since made in relieving serious ills. Above all, it was typically the mother of numerous children who lived long and in good health to be a blessing to those around her, and not the old maids or the childless wives, for longevity is not a special trait of these latter classes of women. The modern dread of deterioration of vitality as the result of frequent child-bearing is quite without foundation in the realities of human experience. Some rather carefully made statistics demonstrate that the old tradition in the matter is not merely an impression but a veritable truth as to human nature's reaction to a great natural call. While the mothers of large families born in the slums, with all the handicaps of poverty as well as hard work against them, die on the average much younger than the generality of women in the population, careful study of the admirable vital statistics of New South Wales shows that the mothers who lived longest were those who under reasonably good conditions bore from five to seven children. Here in America, a study of more favored families shows that the healthiest children come from the large families, and it is in the small families particularly that the delicate, neurotic and generally weakly children are found. Alexander Graham Bell, in his investigation of the Hyde family here in America, discovered that the greatest longevity occurred in the families of ten or more children. So far from mothers being exhausted by the number of children that were born, and thus endowing their children with less vitality than if they had fewer children, it was to the numerous offspring that the highest
