Khartoum is a wretchedly unhealthy town, containing about thirty thousand inhabitants, exclusive of troops. In spite of its unhealthiness and low situation, on a level with the river at the junction of the Blue and White Niles, it is the general emporium for the trade of the Soudan, from which the productions of the country are transported to Lower Egypt, i.e. ivory, hides, senna, gum arabic, and beeswax. During my experience of Khartoum it was the hotbed of the slave-trade. It will be remarked that the exports from the Soudan are all natural productions. There is nothing to exhibit the industry or capacity of the natives. The ivory is the produce of violence and robbery; the hides are the simple sun-dried skins of oxen; the senna grows wild upon the desert; the gum arabic exudes spontaneously from the bushes of the jungle; and the bees-wax is the produce of the only industrious creatures in that detestable country.
