When England made treaties with other slave-holding nations for the suppression of the slave-trade, she provided that captured slaves should be tried before a mixed Commission in which British officers sat. In this treaty they take their chances for freedom before an Ottoman Court. In this connection we regret to announce that Pacha Gordon has resigned, and his resignation has been accepted; and thus Central Africa loses its noble Christian ruler. He went out in 1874 as Governor General of Soudan, “to establish a regular government, to create facilities for commerce, and to destroy the slave-trade in the province entrusted to him,” and his resignation will bring dismay to all who have the cause of humanity at heart. It was at first reported that Ismail Eyoub Pacha had been appointed to take his place, who, while not Gordon Pacha, was, it is said, as good a man for the post as could be found in Egypt. But the _Anti-Slavery Reporter_ now says, “it is officially announced that the actual successor is one Raouf Bey, of evil memory.” This Raouf Bey is spoken of by Sir Samuel Baker in his “Ismailia” as the bosom friend of Abou Saood, whom he describes “as the _incarnation of the slave-trade_, and the greatest slave-dealer on the White Nile.” Colonel Gordon thinks it certain that the slave-dealers will at once resume their operations, and will be unmolested by the new Governor. He estimates that at least 30,000 slaves have annually, for the past twelve years, been brought down from the Bahr Gazelle and Darfur; and Vice-Consul Wylde believes that not less than 50,000 annually cross the Red Sea, who are taken to Egypt, Turkey, and other Mohammedan countries. And now, it seems, the Anglo-Turkish Convention provides that slaves captured by the English shall be handed over to the _Ottoman_ authorities to be by them declared free, and a noted slave-hunter displaces the Christian suppressor of that hellish traffic in the governorship of the slave-hunting grounds. * * * * * MR. H. M. STANLEY ON THE CONGO. [From the Field, March 12.] As the recent movements of this well known African explorer have not been given in detail, the following translation of a letter written by Father Carrie, head of the Congo Mission, dated Landana, December 3, 1879, and published in _Les Missions Catholiques_ (No. 559), may not be without interest.
