the capital of the Egyptian province of Beled-es-Sudan, is situate on the W. bank of the Bahr-el-Azrek, or Blue River, about 1½ mile from its junction with the Bahr-el-Abiai, or White River. At the beginning of the present century only a few huts occupied the site of the present town; but when, in 1822, this territory became an Egyptian province, Khartoom was fixed upon as the seat of government. Being favourably situate near the junction of two large rivers, and near the great caravan route from Darfur and Kordofan, it carries on a very extensive trade. The White River brings into it, from the most distant parts of the country, ivory, ostrich-feathers, gum, &c.; while gold, coffee, senna, and tamarinds, are brought by the Blue River. These articles, as well as slaves, are thence conveyed to Cairo, the Red Sea, and Mediterranean. Pop. estimated at about 20,000.
