Having in some measure explained the nature of the trade with Timbuctoo, we may now proceed to discuss the extent of its territory, and although this does not appear to have been ascertained, yet it may be said to extend northward to the confines of Sahara, or the Desert; a tract of country about ninety miles in breadth; the western boundary is one hundred and thirty miles west of the city, and the eastern extends to the Bahar Soudan, or the Sea of Soudan, which is a lake formed by the Nile El Abeede, whose opposite shore is not discernible; this is the description given of it by the Soudanees, who have visited it; on its opposite or eastern shore begins the territory of white people hereafter mentioned, denominated by the Arabs (N’sarrath) Christians, or followers of Jesus of Nazareth: south of the river is another territory of immense extent, the boundary of which extends to Lamlem, or Melli, which latter is reported to be inhabited by one of the lost, or missing tribes of Israel. The city of Timbuctoo is situated on a plain, surrounded by sandy eminences, about twelve miles north of the Nile El Abeede,[214] or Nile of the Blacks, and three (erhellat) days journey from the confines of Sahara: the city is about twelve miles in circumference, but without walls. A ditch or excavation, about four cubits in depth, and the same in breadth, but without water, circumscribes the city. The town of Kabra, situated on the banks of the river, is its commercial depot, or port. By means of a water carriage east and west of Kabra, great facility is given to the trade of Timbuctoo, from whence the various articles of European, as well as Barbary manufactures brought by the akkabaahs from the north of Africa, are distributed to the different empires and states of Soudan, and the south. This great mart is resorted to by all nations, whither they bring the various products of their respective countries, to barter for the European and Barbary manufactures.
