PREFACE: The phrase "secret service" is intended to cover those comprehensive acts and aspects of policy which for reasons political or commercial, legitimate or otherwise, were enacted purposely below the service and out of the public ken. Of such are the questionable methods of recruiting native labour, the abnormal State-aided precautions for the protection of the Gold and Diamond industries, and the secret native policy - each pregnant factors in South African government that have no counterpart in other countries. ...Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
