The Turkish officials pretended to discountenance slavery; at the same time every house in Khartoum was full of slaves, and the Egyptian officers had been in the habit of receiving a portion of their pay in slaves, precisely as the men employed on the White Nile were paid by their employers. The Egyptian authorities looked upon the exploration of the White Nile by a European traveller as an infringement of the slave territory that resulted from espionage, and every obstacle was thrown in my way.
To organize an enterprise so difficult that it had hitherto defeated the whole world, required a careful selection of attendants, and I looked with despair at the prospect before me. The only men procurable for escort were the miserable cut-throats of Khartoum, accustomed to murder and pillage in the White Nile trade, and excited not by the love of adventure, but by the desire for plunder. To start with such men appeared mere insanity.
