The notorious fecundity of feeble-minded women is emphasized in studies and investigations of the problem, coming from all countries. "The feeble-minded woman is twice as prolific as the normal one." Sir James Crichton-Browne speaks of the great numbers of feeble-minded girls, wholly unfit to become mothers, who return to the work-house year after year to bear children, "many of whom happily die, but some of whom survive to recruit our idiot establishments and to repeat their mothers' performances." Tredgold points out that the number of children born to the feeble-minded is abnormally high. Feeble-minded women "constitute a permanent menace to the race and one which becomes serious at a time when the decline of the birth-rate is... unmistakable." Dr. Tredgold points out that "the average number of children born in a family is four," whereas in these degenerate families, we find an average of 7.3 to each. Out of this total only a little more than ONE-THIRD--456 out of a total of 1,269 children--can be considered profitable members of the community, and that, be it remembered, at the parents' valuation. Another significant point is the number of mentally defective children who survive. "Out of the total number of 526 mentally affected persons in the 150 families, there are 245 in the present generation--an unusually large survival."(2) Speaking for Bradford, England, Dr. Helen U. Campbell touches another significant and interesting point usually neglected by the advocates of mothers' pensions, milk-stations, and maternity-education programs. "We are also confronted with the problem of the actually mentally deficient, of the more or less feeble-minded, and the deranged, epileptic... or otherwise mentally abnormal mother," writes this authority. "The `bad mothering' of these cases is quite unimprovable at an infant welfare center, and a very definite if not relatively very large percentage of our infants are suffering severely as a result of dependence upon such `mothering."'(3) Thus we are brought face to face with another problem of infant mortality. Are we to check the infant mortality rate among the feeble-minded and aid the unfortunate offspring to grow up, a menace to the civilized community even when not actually certifiable as mentally defective or not obviously imbecile?
