To each chapter Of the earlier text-books were appended questions designed to help students to master for themselves the facts Of that Chapter. It was decided (as in the case Of The Future of Africa) that this should no longer be done because such questions are not infre quently used as assignments, and the Helps to Leaders issued by the various Societies have not been properly utilised. At the same time it is hoped that the brief analysis by which each chapter Of this book is prefaced may serve the same purpose Of aiding students to realise more quickly what are the chief points to which thought Should be directed. It only remains to add that for all faults of form the Editor is alone responsible.
