are feeble. Mating out of the race, when mates within he 

 race are available, is prima facie evidence that the individial 

 so mating is a social outcast. It is not surprising that he 

 progeny of such individuals are sometimes feeble. If he 

 parents were diseased, licentious, or feeble-minded, i^ is 

 natural that the children should be of like character. 



Of course not all racial crossing implies such conditiois. 

 Frequently Europeans, when pioneers in a new country iud 

 without mates of their own race, have married native wonen. 

 Such men have not always been social outcasts; frequertly 

 they have been men of great energy, ability, and courige 

 both physical and moral, and free from disease. When in 

 such cases, the mothers belonged to a race with capacity for 

 civilization, the results have been good. Examples ma^ be 

 found among the Indian citizens of our southwest states. 

 But human racial crossing in general is a risky experiment, 

 because it interferes with social inheritance, which after all 

 is the chief asset of civilization. Physically and also intel- 

 lectually, according to Professor Osborn, we are no whit 

 superior to the men of twenty-five thousand years ago. All 

 the advantage which we have over them lies in the accumu- 

 lated experience of the human race since then. 



All this we as individuals learn from our mothers and 

 fathers, or in the schools, the churches, the markets, or the 

 courts of justice. Wide racial crosses unsettle the founda- 

 tions of these agencies of enlightenment. At times it is 

 necessary that some of these agencies be distur'bed in order 

 that we may lay their foundations deeper and broader, but 

 racial crossing leads rather toward the discarding of all 

 foundations of civilization than to improvin.g them. 



Such crosses, therefore, as of Europear^s with Asiatics or 

 Africans can not be recommended as age^acies for the improve- 

 ment of the human race. Physically T^uropeans on one hand 

 and Asiatics or Africans on the oth-^^r, are suflSciently diversi- 

 fied among themselves to allow 'the maximum benefit from 

 intercrossing, without resort^'^ng to crosses with a distinct 

 branch of the human fam^ily. Socially the effects of such
