The general aspect of the Soudan is that of misery; nor is there a single feature of attraction to recompense a European for the drawbacks of pestilential climate and brutal associations. To a stranger it appears a superlative folly that the Egyptian Government should have retained a possession, the occupation of which is wholly unprofitable; the receipts being far below the expenditure, "malgre" the increased taxation. At so great a distance from the seacoast and hemmed in by immense deserts, there is a difficulty of transport that must nullify all commercial transactions on an extended scale. The great and most important article of commerce as an export from the Soudan, is gum arabic: this is produced by several species of mimosa, the finest quality being a product of Kordofan; the other natural productions exported are senna, hides, and ivory. All merchandise both to and from the Soudan must be transported upon camels, no other animals being adapted to the deserts. The cataracts of the Nile between Assouan and Khartoum rendering the navigation next to impossible, the camel is the only medium of transport, and the uncertainty of procuring them without great delay is the trader's greatest difficulty. The entire country is subject to droughts that occasion a total desolation, and the want of pasture entails starvation upon both cattle and camels, rendering it at certain seasons impossible to transport the productions of the country, and thus stagnating all enterprise. Upon existing conditions the Soudan is worthless, having neither natural capabilities nor political importance; but there is, nevertheless, a reason that first prompted its occupation by the Egyptians, and that is in force to the present day. THE SOUDAN SUPPLIES SLAVES. Without the White Nile trade Khartoum would almost cease to exist; and that trade is kidnapping and murder. The character of the Khartoumers needs no further comment. The amount of ivory brought down from the White Nile is a mere bagatelle as an export, the annual value being about 40,000 pounds. The people for the most part engaged in the nefarious traffic of the White Nile are Syrians, Copts, Turks, Circassians, and some few EUROPEANS. So closely connected with the difficulties of my expedition is that accursed slave trade, that the so-called ivory trade of the White Nile requires an explanation.
