THE DEAF AND DUMB.--The condition known as deaf-mutism is due to innate defect in about half of all cases. Deaf children have one or two deaf parents or grandparents. There may be two or three such children in a family. That the deaf should not marry is generally conceded by those who work amongst them. It should be our aim to discourage the intimate association of the adolescent deaf and dumb in institutions. It has been found that such intimate association frequently results in marriage. They should be educated and instructed in the knowledge that they cannot marry. When they understand the eugenic principle upon which this social law is constructed they will be amenable to reason. No process of suasion will be necessary, however, if their intimate association is prevented. THE FEEBLE-MINDED.--This includes the criminal, the imbecile, the insane, and the epileptic. The feeble-minded, technically speaking, belong to the degenerate class. They enter life mentally deficient, not necessarily [38] diseased. They should, therefore, be regarded as fit subjects for educational modification rather than for penal correction or punishment. It is conservatively estimated that there are five million feeble-minded people in the United States to-day and not one-eighth of them are receiving adequate treatment or education. Recent statistics, from various countries, show that the percentage of deficient or feeble-minded children is decidedly on the increase. According to a bulletin issued by the United States Bureau of Education (August, 1912) there are 15,000,000 school children suffering from physical defects which need immediate attention and which are prejudicial to health. It would seem as though the time had passed for anything other than radical measures in the interest of the race.
