That the rule Of my conduct in Africa has not been understood by all, I know to my bitter cost; but with my conscience at ease, and the simple record Of my daily actions, which I now publish, to speak for me, this misunderstanding on the part of a few presents itself to me only as one more harsh experience Of life. And those who read my book will know that I have indeed had a sharp apprehension and keen intelligence Of many such experiences. With reference to the illustrations, I should mention that I carried a photographic apparatus with me across the Continent, and so long as my dry plates held out I never lost an Opportunity Of Obtaining a good view, and when my plates were used up I found the re?ection Of the scenes on the ground glass Of my camera an invaluable aid to my unpractised pencil.
