will give a summary of the conclusions which the detailment of facts seems to justify: 1. The lines of intermarriage of the Juke blood show a minimum of crime. 2. In the main, crime begins in the progeny where the Juke blood has married into X—— (non-Juke blood). 3. The illegitimate branches have chiefly married into X——. 4. The illegitimate branches produced a preponderance of crime. 5. The intermarried branches show a preponderance of pauperism. 6. The intermarried branches show a preponderance of females. 7. The illegitimate branches produced a preponderance of males. 8. The apparent anomaly presents itself that the illegitimate criminal branches show collateral branches which are honest and industrious. We here find a most curious and interesting history and an epitome of conclusions which challenges serious consideration. That the family of the “Jukes” was more vicious than their neighbors whose surroundings were similar cannot be disputed, and the question arises, What was there peculiar and exceptional in their case that made the fact to be such? The habits of life of the immediate descendants of Max were bad in the extreme, but partly forced upon them by environments. These people dwelt in mud-built cabins, with but one apartment, which served all the purpose of a tenement. Here they slept and ate, and of course privacy was rendered entirely impossible. Decency and modesty were out of the question, and the anomaly of whole families utterly bereft of all regard for domestic morals began to exhibit itself. We will now lay down a fundamental principle, by the light of which we hope to be able to solve the knotty question of this intense perversity of a series of blood-related generations, and Mr. Dugdale himself will furnish the proofs.
