CONTROL OF IMMIGRATION 83 



or mix them in any form deemed desirable, and to see that individuals, or 

 better still families, that may constitute these racial groups, are within 

 what we could call their biological rights in demanding that the individual 

 characteristics possessed, or that form eugenic characters, are not mixed 

 with those resulting from cacogenic factors, nor should they disfigure 

 themselves when resulting in divergent or discordant mixtures in their 

 descendants. 



We should also tend to facilitate the movement throughout the whole 

 world, of those individuals whom biologically, in no way harm the natives 

 where they may desire to reside. 



All in all, migratory restriction, and non-restriction of certain types of 

 men all over the earth, should be based on the different biological consti- 

 tutions of each individual and each race, to the final biological betterment 

 of humanity, and its proper grouping, which constitutes the only sure basis 

 of happiness, the principal ways of obtaining which are the biological 

 selection of the individual as the fathers of each generation to come, and the 

 eugenic considerations of the mixing of the races. 



At this moment the most feasible measures for enabling the nations to 

 secure control over immigration, in my opinion, are the following: 



1. The studying and listing of the biological characters of the native 

 population; and of the migratory one. Its classification of desirables and 

 undesirables (eugenics and cacogenics and also of those who can be consid- 

 ered as convergent, divergent, concordant or discordant). 



2. A study of racial groups constituting the native population and the 

 relative proportion of each group. The same study applied to the immi- 

 grant population. 



3. A study of the relation existing between each racial group and the 

 condition of environment existing in the receiving nation. A sanitary 

 study of the immigrating population. 



4. Determination of the type, or types, of desirable and undesirable 

 immigrants from the viewpoints of race and individuality and also in rela- 

 tion to sanitary conditions. 



5. Determination of the total immigration permissible, and the assign- 

 ment of convenient quotas for each group. 



6. Biological selection of the immigrant in the country of origin. 



7. Sanitary selection of immigrants on arrival. 



8. Deportation of immigrants or their descendants of the first generation 

 when it is proven that they possess inadmissible characteristics. In case 

 of mixed descendants, verification of possible inheritance of said character- 

 istics from immigrant gamete, and if not found, to proceed to final admis- 

 sion of the individual.
