"When we come to inquire into the cause of feeble-mindedness, alcoholic heredity, syphilitic heredity, and consanguineous marriages are found to be the chief etiological factors. Bourneville claims that 48 per cent. of the idiots and imbeciles are the offspring of alcoholic parents.... Acute and chronic diseases in the parents, fright, shock, injuries, parental neglect, faulty education, poverty, malnutrition, social dissipation and lack of proper control are all well-known factors in the production of feeble-mindedness. "Segregation of the feeble-minded is advocated by medical authority the world over, and when this is done they can be made under appropriate medico-pedagogic treatment to become largely self-supporting. "As an economical as well as a humane measure, the various States can well afford to make such provision, more especially for the large body of feeble-minded who are now without any medical care whatever. Moreover, where it is possible, laws prohibiting the marriage of such as well as all other defectives should be passed and enforced." WHAT THE CARE OF THE INSANE COSTS.--The total cost of the care of the insane, in this country, has been estimated to be $165,000,000 a year. In estimating the cost of the insane we must take into account the value or worth of each adult to the State. This value has been computed to be $700 a year. If, upon this basis, we count the adult membership of the insane class between the ages of eighteen and forty-five, we find that their worth is roughly about $132,000,000. The cost of maintenance in the various insane institutions is about thirty-three millions of dollars a year. It would be quite possible to justly increase this total by estimating the worth of the help whose whole time is devoted to the care of the insane. If these individuals worked at some other trade or profession, their time would. be of value to the [44] state in general--not to a class who should be non-existent. The cost to the state of the potential criminal is not included in this estimate. From the above figures it may be observed that it costs more to simply maintain the insane each year than it costs to work the Panama Canal; or to pay for the total cost of the Executive, Legislative and Judicial departments of our government. The total cost is more than the entire value of the wheat, corn, tobacco, and dairy and beef products exported each year from this country.
