"I have learned with equal pain and indignation that the Khedive and his subordinate officers have permitted the resuscitation of the slave-trade in Darfour and the other provinces of central and equatorial Africa, and that fresh parties of slave-hunters are forming at Obeyed in Kordofan, and that every order which I gave concerning the suppression of this abomination has been cancelled... This news is very disheartening, especially when one realises the immense misery which will ensue to the remains of these poor tribes of helpless negroes."
