It cannot be too strongly impressed upon persons interested in the housing problem that over-crowding means a violation of childhood in every degree, from the indecencies of mere childish horse-play to complete debauchery. P. 22. There are two types of feeble-minded girls who are almost inevitably destined to prostitution. There is first the large proportion whose sexual inclinations are abnormally strong, or whose power of self-control over natural impulses is abnormally weak. 2—There is the large class who are non-resistant. They have no active impulse to seek out men, but they will yield to any one who approaches them. There are three important factors that drive the feeble-minded into prostitution by excluding them from other occupations. 1—They often lose their characters at a very early age. A marked characteristic of the feeble-minded is the precocity of their sexual impulse. 2—It is easy enough for any feeble-minded girl to get and keep light, unskilled work at girl’s wages, but not so easy for her to pass like the girl of normal intelligence, from girl’s to woman’s work at the age of 17 or 18, for she is rarely worth woman’s wages. Therefore she finds herself bored by monotonous work and low pay just at the time that she is particularly attractive to man, and her sexual impulses are at their strongest. Very naturally the feeble-minded girl with her incapacity to perceive the consequences turns from her unsatisfying employment to the new life of excitement and easy gain that offers itself. 3—If feeble-minded girls do succeed in getting respectable situations they are very likely to lose them because of their lack of intelligence and general inefficiency. And even if they should discharge their duties in a satisfactory manner they have a curious distaste for staying for any time in one place, and tend to drift from situation to situation. P. 127–128. Another characteristic of the feeble-minded is their notorious fertility. The superior fertility of the feeble-minded has been proved beyond dispute by statistical inquiry. _DELINQUENCY AND MENTAL DEFICIENCY. Dr. Olga Bridgman. The Survey, June 13, 1914._ Report of examination of 118 consecutive admissions at the Illinois Training School for Girls at Geneva. Of the 118, 105, or 89%, showed a retardation of three years or more, thus ranking as mentally deficient, 6% were backward, being one or two years retarded, and six, or 5% were graded as normal. According to the Binet tests then, 97% of the children sent to this institution are mentally defective. _COMMERCIALIZED PROSTITUTION IN NEW YORK CITY. George Kneelands. Century Co., New York, 1913.
