We must not omit to mention that while Livingstone was making his terrible disclosures respecting the havoc wrought by the slave-trader in east central Africa, Sir Samuel Baker was striving to effect in north central Africa what has been so successfully accomplished in the Congo State. During his expedition for the discovery of the Albert Nyanza, his explorations led him through one of the principal man-hunting regions, wherein murder and spoliation were the constant occupations of powerful bands from Egypt and Nubia. These revelations were followed by diplomatic pressure upon the Khedive Ismail, and through the personal influence of an august personage he was finally induced to delegate to Sir Samuel the task of arresting the destructive careers of the slavers in the region of the upper Nile. In his book _Ismailïa_ we have the record of his operations by himself. The firman issued to him was to the effect that he “was to subdue to the Khedive’s authority the countries to the south of Gondokoro, to suppress the slave trade, to introduce a system of regular commerce, to open to navigation the great lakes of the equator, and to establish a chain of military stations and commercial depots throughout central Africa.” This mission began in 1869, and continued until 1874. On Baker’s retirement from the command of the equatorial Soudan the work was intrusted to Colonel C. G. Gordon--commonly known as Chinese Gordon. Where Baker had broken ground, Gordon was to build; what his predecessor had commenced, Gordon was to perfect and to complete. If energy, determination, and self-sacrifice received their due, then had Gordon surely won for the Soudan that peace and security which it was his dear object to obtain for it. But slaving was an old institution in this part of the world. Every habit and custom of the people had some connection with it. They had always been divided from prehistoric time into enslavers and enslaved. How could two Englishmen, accompanied by only a handful of officers, removed 2000 miles from their base of supplies, change the nature of a race within a few years? Though much wrong had been avenged, many thousands of slaves released, many a slaver’s camp scattered, and many striking examples made to terrify the evil-doers, the region was wide and long; and though within reach of the Nile waters there was a faint promise of improvement, elsewhere, at Kordofan, Darfoor, and Sennaar, the trade flourished. After three years of wonderful work, Gordon resigned. A short time afterwards, however, he resumed his task, with the powers of a dictator, over a region covering 1,100,000 square miles. But the personal courage, energy, and devotion of one man opposed to a race can effect but little. His peculiar qualities shone forth conspicuously. He underwent the same trials as formerly. He signalized his detestation of the slavers by severe punishments, by summary dismissals of implicated
