=Cost of Caring for Our Mentally Disordered.--=Doctor Charles L. Dana, member of the National Committee for Mental Hygiene, estimated in 1904 that the actual cost of caring for feeble-minded and insane in the United States amounted to sixty million dollars, to which should be added the corresponding loss in industrial activity on the part of the afflicted,--at least twenty million dollars more, and he figures that the amount was increasing at the rate of four per cent. per annum. Many investigators concur in the opinion that our insane and feeble-minded alone cost us far above one hundred million dollars. Adding to this economic burden the cost of our delinquents and criminals the total expense becomes stupendous. And when we consider still further the even greater burden of suffering of the unfortunates themselves and the sorrows of those to whom they are dear, a burden not measurable in money, the feeling that something must be done to relieve the situation becomes overpowering. =Importance of Rigid Segregation of Feeble-Minded.--=As regards the really feeble-minded little can be done beyond making them as happy as possible and developing the limited gifts they have been given by nature. Their teaching must be in the main concrete and simple. At the age of puberty it is imperative to see that the sexes are separated and kept under sufficient permanent supervision to prevent all possibility of procreation. There is neither economic nor common sense in even allowing the remotest chance of such occurrences as the following: "This is the case of a feeble-minded and epileptic woman who had six children by various persons while an inmate of a county poor house. One child at the age of eighteen died in the almshouse, two died in infancy, one was epileptic (the son of a man with a criminal record) and two who are now living in the almshouse are feeble-minded, one being the son of a negro." Again, we find a superintendent of an English almshouse reporting that one hundred and two out of one hundred and five children born there in five years were feeble-minded. As conditions are to-day every institution for the feeble-minded has a long waiting list and the same is true of most asylums for the insane. Instead of providing the prolonged care necessary for such patients, institutions are forced to discharge many prematurely in order to make room for more urgent cases.
