SOCIAL AND WORLD ASPECTS 231 



numbers about 246,500, the Japanese predominating 

 in numbers. From a decade of observation of this 

 microcosmic mehing-pot, the conclusion is reached 

 that such racial intermingling is usually undesirable 

 in its results. Most of the Caucasian*-Hawaiians 

 seem to blend the least desirable traits of both 

 parents, and intermarriages of North European and 

 American stocks with dark-skinned races are con- 

 sidered biologically wasteful. 



Similarly Lundborg (1920), from a study of Swedish 

 conditions, concludes that the crossing of races 

 degenerates the constitution and increases degrada- 

 tion. He finds such crossing much more common in 

 the poorer and lower classes, while the middle classes 

 are more homogeneous. In the lower classes are 

 more frequently found individuals with other race 

 characters — e.g., darker hair and eyes. Mjoen (1922) 

 has examined the results of crosses in Norway between 

 the Nordics and the Mongoloid Laplanders . He found 

 the first generation to be taller and heavier than the 

 tall Nordic parent (owing to heterosis), but that this 

 increase in size is lost in later generations. Also, 

 frequently in crosses between Lapps and Norwegians, 

 especially when Alpine blood was also present, a 

 mentally unstable type is produced, the lack of 

 balance being shown by stealing, lying, and drinking. 

 A similar unbalanced type frequently arises from 

 crosses between American Indians and French or 

 English. The writer concludes that as regards these 

 matings, the pure races have the advantage in every 

 way. For example, the incidence of tuberculosis is 

 the lowest (i-i to 1-5) where the Nordic race is 

 comparatively pure, and highest (3-6 to 4) in the 

 region where there is the largest race mixture. 



As regards world eugenics, then, it would appear

 Americans belonging to the " white " race.
