In my first chapter I showed that the rising tide of color to-day finds itself confronted by dikes erected by the white race during the centuries of its expansion. The reader will also remember that white expansion has taken two forms: settlement and political control. These two phases differ profoundly in character. Areas of settlement like North America have become integral portions of the white world. On the other hand, regions of political control like India are merely white dependencies, highly valuable perhaps, yet in the last analysis held by title of the sword. Between these clearly contrasted categories lies an intermediate class of territories typified by South Africa, where whites have settled in large numbers without displacing the native populations. Lastly, there exist certain white territories which may be called "enclaves." These enclaves have become thoroughly white by settlement, yet they are so distant from the main body of the white world and so contiguous to colored race-areas that white tenure does not possess that security which settlement and displacement of the aborigines normally confer. Australia typifies this anomalous class of cases. The white defenses against the colored tide can be divided into what may be termed the "outer" and the "inner" dikes. The outer dikes (the regions of white political control) contain no settled white population, so that their abandonment, whatever the political or economic loss, would not directly affect white race-integrity. The question of their retention or abandonment should therefore (save in a few exceptional cases) be judged by political, economic, or strategic considerations. The inner dikes (the areas of white settlement), however, are a very different matter. Peopled as they are wholly or largely by whites, they have become parts of the race-heritage, which should be defended to the last extremity no matter if the costs involved are greater than their mere economic value would warrant. They are the true bulwarks of the race, the patrimony of future generations who have a right to demand of us that they shall be born white in a white man's land. Ill will it fare if ever our race should close its ears to this most elemental call of the blood. Then, indeed, would be manifest the writing on the wall. That issue, however, is reserved for the next chapter. Let us here examine the matter of the outer dikes--the regions of white political control. There, where the white man is not settler but suzerain, his suzerainty should, in the last analysis, depend on the character of the inhabitants.
