The second result will be favorable or unfavorable, depending on the characters which go into the cross; and it is not possible to predict the result in human matings, because the various racial characters are so ill known. It is, therefore, not worth while here to discuss at length genetic theory. In general it may be said that some valuable characters are likely to disappear, as the result of such crosses, and less desirable ones to take their place. The great bulk of the population resulting from such racial crosses is likely to be more or less mongrel in nature. Finally, some individuals will appear who combine the good characters of the two races, without the bad ones.
The net result will therefore probably be some distinct gain, but a greater loss. There is danger that complex and valuable traits of a race will be broken down in the process of hybridization, and that it will take a long time to bring them together again. The old view that racial crosses lead fatally to race degeneration is no longer tenable, but the view recently advanced, that crosses are advantageous, seems equally hasty. W. E. Castle has cited the Pitcairn Islanders and the Boer-Hottentot mulattoes of South Africa as evidence that wide crosses are productive of no evil results. These cases may be admitted to show that such a hybrid race may be physically healthy, but in respect of mental traits they hardly do more than suggest the conclusion we advanced in our chapter on the Color Line,—that such miscegenation is an advantage to the inferior race and a disadvantage to the superior one.
On the whole, we believe wide racial crosses should be looked upon with suspicion by eugenists.
The colonizers of North America mostly belonged to the Nordic race.[143] The earlier immigrants to the United States,—roughly, those who came here before the Civil War,—belonged mostly to the same stock, and therefore mixed with the early settlers without difficulty. The advantages of this immigration were offset by no impairment of racial homogeneity.
But the more recent immigration belongs mostly to other races, principally the Mediterranean and Alpine. Even if these immigrants were superior on the average to the older population, it is clear that their assimilation would not be an unmixed blessing, for the evil of crossbreeding would partly offset the advantage of the addition of valuable new traits. If, on the other hand, the average of the new immigration is inferior in quality, or in so far as it is inferior in quality, it is evident that it must represent biologically an almost unmixed evil; it not only brings in new undesirable traits, but injures the desirable ones already here.
E. A. Ross has attempted to predict some of the changes that will take place in the population of the United States, as a result of the immigration of the last half-century.[144] "It is reasonable," he thinks, "to expect an early falling off in the frequency of good looks in the American people." A diminution of stature, a depreciation of morality, an increase in gross fecundity, and a considerable lowering of the level of average natural ability are among other results that he considers probable. Not only are the races represented in the later immigration in many cases inferior in average ability to the earlier immigrant races, but America does not get the best, or even a representative selection,[145] from the races which are now contributing to her population. "Europe retains most of her brains, but sends multitudes of the common and sub-common. There is little sign of an intellectual element among the Magyars, Russians, South Slavs, Italians, Greeks or Portuguese" who are now arriving. "This does not hold, however, for currents created by race discrimination or oppression. The Armenian, Syrian, Finnish and Russo-Hebrew streams seem representative, and the first wave of Hebrews out of Russia in the eighties was superior."
While the earlier immigration brought a liberal amount of intelligence and ability, the later immigration (roughly, that of the last half century) seems to have brought distinctly less. It is at present principally an immigration of unskilled labor, of vigorous, ignorant peasants. Some of this is "promoted" by agents of transportation companies and others who stand to gain by stirring up the population of a country village in Russia or Hungary, excite the illiterate peasants by stories of great wealth and freedom to be gained in the New World, provide the immigrant with a ticket to New York and start him for Ellis Island. Naturally, such immigration is predominantly male. On the whole, females make up one-third of the recent inflow, but among some races—Greeks, Italians and Roumanians, for example—only one-fifth.
In amount of inherent ability these immigrants are not only less highly endowed than is desirable, but they furnish, despite weeding out, altogether too large a proportion of the "three D's"—defectives, delinquents and dependents. In the single year 1914 more than 33,000 would-be immigrants were turned back, about half of them because likely to become public charges. The immigration law of 1907, amended in 1910, 1913 and 1917, excludes the following classes of aliens from admission into the United States:
Idiots, imbeciles, feeble-minded persons, epileptics, insane persons, persons who have been insane within 5 years previously; persons who have had two or more attacks of insanity at any time previously or who are affected by constitutional psychopathic inferiority or chronic alcoholism; paupers, vagrants, persons likely to become public charges; professional beggars, persons afflicted with tuberculosis or with a loathsome or contagious disease; persons who have been convicted of a crime involving moral turpitude; polygamists, anarchists, contract laborers, prostitutes, persons not comprehended within any one of the foregoing excluded classes who are found to be and are certified by the examining surgeon as being mentally or physically defective, such mental or physical defect being of such a nature as to affect the ability of the alien to earn a living.
