foregoing traits is bringing a high degree 

 of success. Another significant series 

 of combinations occurs in line C whereby 

 defects concentrate in a single member 

 of the third generation, who dies without 

 issue, while the combination of medium 

 or high aggressiveness and perseverance 

 with calculating and other mental 

 abilities produces average efficiency of 

 various types in the later generations. 



The recent extension of physical and 

 mental tests in determining types of 



efficiency in the National Army, gives 

 promise of far more accurate ratings in 

 future studies of this kind. By such 

 means this principle of segregation 

 should be found capable of extension in 

 directions at present unthought of. 

 Such extension would provide a means of 

 more accurate prediction as to the out- 

 come of given matings and the trend of 

 development in particular strains. Such 

 extension would prove highly valuable 

 for constructive eugenics. 



The Immigration Of Orientals 



Cambridge, Mass., Mar. 8, 1918. 

 The Editor of the Journal of Heredity. 

 SirT should like to make one comment 

 on the subject of Dr. Sidney L. Guhck's 

 League for Constructive Immigration 

 Legislation, which is referred to on page 

 379 of the December number of the 

 Journal. On paper, the principles of 

 this new league read extremely well, 

 and appeal to many persons who are 

 seriously concerned regarding the proba- 

 ble future volimie of immigration to this 

 country. It should be pointed out, 

 however, that it is an essential part of 

 Dr. Gulick's program to repeal our 

 present Chinese Exclusion Act; to end 

 our present "Gentleman's Agreement" 

 with Japan, and to have only one 

 general immigration law. In other 

 words, the plan is to treat all aliens 

 alike, admitting Chinese and Japanese 

 on the same terms as all other nationali- 

 ties. While the number of Orientals to 



be admitted would necessarily be very 

 small, for a time, under the proposed 

 limitation to a certain percentage, these 

 numbers would soon automatically in- 

 crease. Furthermore, the percentages to 

 be admitted could easily be raised. The 

 Gulick plan also involves the naturaliza- 

 tion of the Oriental. 



It is these portions of the league's 

 program which are strongly opposed 

 by many persons who thoroughly believe 

 in the restriction of immigration; and 

 those who are interested in eugenics, 

 and in the future character of the 

 American race, may well bear these 

 facts in mind. The Gulick plan pro- 

 poses to put the thin edge of a wedge 

 under the door which our national policy 

 has built against Oriental immigration. 

 It is a very thin wedge now, but it is a 

 wedge.
