The disappearance of half-breeds is an illustration of the damage done by lack of adjustment to the climate. The mulatto, for instance, has characters half way between those of the parent type; his skin is too light for him to live in the tropics, and if he lives in the North his nostrils are too open for the cold air. Indeed, there is no climate on earth suitable for him, and he is damaged wherever he lives. He is "the man without a country".
The evidence as to the mulatto is universally to the effect that he shows less resistance to disease than either parent, and also does not stand surgical operations well. It is generally assumed that the mixture produces a weak tissue, but it is more logical to assume that his tissues are the same as the parental, but that they are being constantly bombarded by adversities from which each parent is protected. At any rate, mulatto families constantly tend to extinction by small birth rate and huge death rate, and in spite of the enormous production of such types in America they do not constitute nearly as high a percentage of our colored population as they should if they were not unfit for the environment.
Our records for 8,000 years show that the negro cannot mix with the whites, and we can safely predict that he never will. The mulatto invariably dies out unless new black blood is infused into the mixed race, and though some families survive a few generations, as a rule there is absolute extinction of such feeble offspring. The Griquas were half-breeds from Dutch Boers and Hottentots, numerous at the Cape at the end of the 18th century, but practically extinct in 1825. Dutch half-breeds in Java and Sumatra are sterile in the third generation. In India the half-breeds - Eurasians - are feeble and perish. Mulattoes from French or Spanish fathers last the longest, but eventually die out. The hideous Huns who overran Europe and married native European women have not left a trace - all their half-breeds gradually dying out. Half-breeds between Chinese and Japanese are not permanent, and those between Japanese and the Ainus of Yezzo are also sterile as a rule.
The Spanish mestizo race in the Philippines, is a hybrid destined to early extinction. It is now the ruling race because it is more intelligent than the native Malay, but it is unfit for the climate. Being feeble, the mestizo cannot work like the native and, therefore, cannot exercise sufficiently to keep healthy. He has not sufficient intelligence to compete with whites and occupies a subordinate place in trade and all the professions. As a rule mestizo families date back not further than a Spanish grandfather - the older families seem to have perished already. It takes little prophesy, then, to foretell their early extinction. If they could have built up a government, it would have perished with them, and the Islands relapse into savagery in the hands of the native Malay, as Egypt relapsed into chaos every time its invading civilizers perished.
Permanent hybrid races may arise from the union of two closely similar races because the mixed types are so slightly out of adjustment to either climate that they can furnish fit variations to survive, hence, such hybrids as are found in many European localities are more or less permanent, but there is no exception to the rule of absolute extinction of hybrids between widely differing races. Volumes might be written about the pitiful frailness and feebleness of these races, and the awful physical degeneration which comes from living their unnatural lives. It is a rich field in which to study the ordinary stigmata of degeneration so frequent in the mestizo and so much rarer in the Malay.
It is said that Aguinaldo and all his cabinet, with few exceptions, were Chinese mestizos, and this illustrates the greater fitness of Chinese than Spaniard for this blending. Both Chinese and Spaniard have black hair and an olive complexion, so that they are very nearly equally fitted for the climate. Moreover, the Chinese and Malays are of the same broad-headed, Asiatic type, and in accordance with law, their half-breeds must be the more vigorous of the two. The Malay is merely an earlier Asiatic wave than the Chinese, though coming from the mainland through Sumatra and Borneo. There is the same blood relation of Malay to Chinese as there is of Berber to Italian.
It is known that the longer a race has been under civilization where its variations can survive, the greater are the varieties of brain, so different from the uniformity of brain in a savage race. Hence, there is in China every type from the coolie, so stupid as to be merely a beast of burden, to some of the brainiest men in the world. Some Chinese immigrants in the Philippines are highly intelligent, and transmit this to their half-breed offspring. The term Chinese mestizo conveys no idea as to the amount of intelligence of the man, for there can be every type, but these facts show why there are so many able men of this mixture. The Chinese are a Northern race and really unfit for this Southern climate, and their half-breeds are sure to die out in time, but it will, of course, be a long time, and they do not show nearly so much of the degeneration found among Spanish mestizos.
There is a current idea that the Chinese can upset natural law and be an exception in the zoological world - independent of climate - or as one man says, they can flourish from Siberia to Singapore, but the very lightness of their skins needed in cold places is a'distinct disadvantage in the tropics where they must hide from the light like white ants. They huddle in dark houses, carefully exclude the glare, hide in midday and are nearly wholly devoted to house employments. Though they do manage truck farms, they leave tropical farming to the natives, just as intruders do all the world over; indeed, the Chinese do not compete with any labor which was necessary in pre-Spanish days. All trades imported since that time, watchmaking, carpentry, cabinet maker, machinist, etc., must have imported workmen, as the Malay is unable to grasp them. Malays have learned to be machinists, blacksmiths, turners, carpenters, painters, but the good ones are very few and they are generally half-breeds. Hence, the cry in the Islands is, and always has been, for imported laborers to do the work of imported trades beyond the abilities of Malays. But to say that this imported labor is to push the native to the wall is utter nonsense as it is unnatural - the native will remain what he always has been - farmer and house builder.
