We must complete our survey of the resistances against which the Open Conspiracy has to work by a few words about the negro world and the regions of forest and jungle in which barbaric and even savage human life still escapes the infection of civilisation. It seems inevitable that the development of modern means of communication and the conquest of tropical diseases should end in giving access everywhere to modern administration and to economic methods, and everywhere the incorporation of the former wilderness in the modern economic process means the destruction of the material basis, the free hunting, the free access to the soil, of such barbaric and savage communities as still precariously survive. The dusky peoples, who were formerly the lords of these still imperfectly assimilated areas, are becoming exploited workers, slaves, serfs, hut-tax payers or labourers to a caste of white immigrants. The spirit of the plantation broods over all these lands. The negro in America differs only from his subjugated brother in South Africa or Kenya Colony in the fact that he also, like his white master, is an immigrant. The situation in Africa and America adjusts itself therefore towards parallel conditions, the chief variation being in the relative proportions of the two races and the details of the methods by which black labour is made to serve white ends. In these black and white communities which are establishing themselves in all those parts of the earth where once the black was native, or in which a sub-tropical climate is favourable to his existence at a low level of social development, there is--and there is bound to be for many years to come--much racial tension. The steady advance of birth control may mitigate the biological factors of this tension later on, and a general amelioration of manners and conduct may efface that disposition to persecute dissimilar types, which man shares with many other gregarious animals. But meanwhile this tension increases and a vast multitude of lives is strained to tragic issues.
