border-land between genius and insanity. The essential character of all these racial mixtures is a lack of harmony—both physical and mental—in the first few generations. Then, if the strain survives, it is by the slow reversion to one of the parent types—almost inevitably the lower. The temporary advantage of mere numbers enjoyed by the inferior classes in modern democracies can only be made permanent by the destruction of superior types—by massacre, as in Russia, or by taxation, as in England. In the latter country the financial burdens of the war and the selfish interests of labor have imposed such a load of taxation upon the upper and middle classes that marriage and children are becoming increasingly burdensome. The best example of complete elimination of a dominant class is in Santo Domingo. The horrors of the black revolt were followed by the slow death of the culture of the white man. This history should be studied carefully because it gives in prophetic form the sequence of events that we may expect to find in Mexico and in parts of South America where the replacement of the higher type by the resurgent native is taking place. In the countries inhabited by a population more or less racially uniform the phenomenon of the multiplication of the inferior classes fostered and aided by the noble but fatuous philanthropy of the well-to-do everywhere appears. Nature’s laws when unchecked maintain a relatively fixed ratio between the classes, which is greatly impaired in modern society by humanitarian and charitable activities. The resurgence of inferior races and classes throughout not merely Europe but the world, is evident in every despatch from Egypt, Ireland, Poland, Rumania, India and Mexico. It is called nationalism, patriotism, freedom and other high-sounding names, but it is everywhere the phenomenon of the long-suppressed, conquered servile classes rising against the master race. The late Peloponnesian War in the world at large, like the Civil War in America, has shattered the prestige of the white race and it will take several generations and perhaps wars to recover its former control, if it ever does regain it. The danger is from within and not from without. Neither the black, nor the brown, nor the yellow, nor the red will conquer the white in battle. But if the valuable elements in the Nordic race mix with inferior strains or die out through race suicide, then the citadel of civilization will fall for mere lack of defenders.
