1900. With over 50 illustrations by C. R. Knight and J. M. Gleeson. Du Chaillu, American explorer writes in the Introduction: The world of the Great Central African Forest is a remarkable one. Its denizens range from the huge elephant to the smallest ant, and in its dark recesses and almost impenetrable jungle I have studied the life of these creatures. From close observation and persistent study I have arrived at the conclusion that animals, birds, reptiles, ants, spiders, etc., possess great power of apprehension and prevision; that creatures of the same species have understanding with one another, either by voice, sign or by other ways unknown to man; otherwise they could not act with such harmony and deliberation. A wonderful firsthand account of the habits of the animals of Africa.
