These sub-divisions are, perhaps, somewhat arbitrary. The distinctiveness here given to them cannot be absolutely preserved. There is, for instance, a natural tendency for both a and b to merge into c as, through efflux of time, the originating cause and motive of contact is obscured by developments to which contact has given rise.
Thus racial contention for actual possession of the soil, and political action often resulting in so-called treaties of Protectorate thoroughly unintelligible to the African signees, are both landmarks upon the road leading to eventual administrative policy: i.e., to direct government of the black man by the white.
Nevertheless administrative policy in itself has assumed a peculiar character and precision in certain extensive regions of Africa, irrespective of the antecedent events which led up to it. When this has occurred, as in the Congo and French Congo, for instance, issues have been raised which call for special and separate treatment.
The next chapter is concerned with the period of the slave trade.
