50 HEREDITY AND SOCIAL FITNESS 



and was prominent in other school activities. Followed his work at 

 the normal school with the Chautauqua course in physical training. 

 Last year had charge of a boys' cliib in the Middle West, and in the 

 coming year will have charge of athletics in a Y. M. C. A. Has mar- 

 ried V-240, formerly a teacher in the normal school. They have a 

 little girl (VI-167) 4 weeks old. 



V-243, born 1893. A very pretty, modest girl, passing for 16 rather 

 than 20. Is taking the normal course, in which she finds the languages 

 and drawing preferable to mathematics. She is helpful at home and 

 decidedly musical. 



V-241, 242, twins. Miscarriage through the father's abuse. 



Summary of Line D. 



In surveying this line, one is struck by the diversity exhibitecf by its 

 various branches, — a diversity which is comparable to that of Line A, 

 although here the trend is in the main downward. Four of the five 

 diverse children of the founder married into widely differing strains. 

 In the second generation, marriage of the superior member (III-43) into 

 a strain showing similar traits results in the presence of these traits 

 in the following generation. This good effect is, however, again dis- 

 sipated by marriage of the two following generations into stock which 

 is deficient in these traits. Marriage of the inferior III-40 into strong 

 stock obliterated the characteristic defects for at least the succeeding 

 generation. The later history of these descendants has not been fol- 

 lowed. The marriage of III-38 with her double cousin is interesting. 

 Each belonged to a fraternity showing a splitting-up into high, medium, 

 and low grades of the traits in question. Their five children tend to 

 fall into three classes, much as do the fraternities to which their 

 parents belonged. The most degenerate branch arises where, in the 

 second generation, a member lacking calculating ability and showing 

 low aggressiveness and perseverance marries a sex-ofTender also lack- 

 ing in the traits just mentioned. Here the original defect in number 

 and proportion persists in a large proportion of the offspring, com- 

 bined, in some instances, with chastity and industry, in others with 

 shiftlessness and lack of sex control. None of the combinations of 

 these defective germ-plasms are such as to insure the presence of 

 socially effective traits, and we have, as a result, vagrancy, shiftless- 

 ness, sex immorality, and petty criminality. In this branch high 

 infant mortality and low fecundity have resulted in rather small 

 numbers in the latest generation, but those who are reproducing are 

 doing so in numbers which constitute a distinct menace and threaten 

 more serious problems to the community and the state in the near 

 future. This is true also of the branch engendered by IV-113 and 114.
