THE publishers of this book asked me to write a series of works which should deal with " real adventures," in parts of the world either wild and uncontrolled by any civilized government, or at any rate regions full of dangers, of wonderful discoveries; in which the daring and heroism of white men (and sometimes of white women) stood out clearly against backgrounds of unfamiliar landscapes, peopled with strange nations, savage tribes, dangerous beasts, or wonderful birds. These books would again and again illustrate the first coming of the white race into regions inhabited by people of a different type, with brown, black, or yellow skins; how the European was received, and how he treated these races of the soil which gradually came under his rule owing to his superior knowledge, weapons, wealth, or powers of persuasion. The books were to tell the plain truth, even if here and there they showed the white man to have behaved badly, or if they revealed the fact that the American Indian, the Negro, the Malay, the black Australian was sometimes cruel and treacherous.
