GENETICS 



laws ; a quickened eugenic sentiment ; sexual segrega- 

 tion of defectives; and finally, drastic measures of 

 asexualization when necessary. Providing for the eu- 

 genic elimination of defectives is as truly a civic duty 

 as administering charity to them after they are born. 



A. CONTROL OF IMMIGRATION 



The enforcement of immigration laws tends to debar 

 from the United States not only many undesirable indi- 

 viduals, but also incidentally to keep out much poten- 

 tially bad germplasm that, if admitted, might play 

 havoc with future generations. 



For example, during the year of 1908, 65 idiots, 

 121 feeble-minded, 184 insane, 3741 paupers, 2900 

 individuals having contagious diseases, 53 tuberculous 

 individuals, 136 criminals, and 124 prostitutes were 

 caught in the sieve at Ellis Island alone and turned 

 back from this country by the immigration officials 

 in spite of the fact that an average of only 8 cents a 

 head was expended upon inspection. 



These 7000 and more individuals probably were the 

 bearers of very little germplasm that we are nationally 

 not better off without. 



Eugenically, the weak point in the present applica- 

 tion of immigration laws is that criteria for exclusion 

 are phenotypic in nature rather than genotypic, and 

 consequently much bad germplasm comes through our 

 gates hidden from the view of inspectors because the 

 bearers are heterozygous, wearing a cloak of desirabil- 

 ity over undesirable traits.
