Among the rivers which empty into the Black sea is the Danube, which originates in two small streams that have their sources in the eastern declivity of the Black forest, in the grand-duchy of Baden, at an elevation of three thousand feet above the level of the sea, and uniting at Donaueschingen. Its general course is from west to east, falling into the Black sea by three principal outlets, called respectively the Kilia, Sulineh, and the Edrillis mouths, as represented in the subjoined engraving.
