Both Servia and Rumania are largely and progressively agricultural and pastoral countries, and much of the flat country through which the river winds, is pasture and forest. The villages that are passed on either bank do not call for special mention, until, at Kossiak, is reached an important centre of the salt industry, and, at Radujevac, the last town in Servia--for shortly beyond it the river Timok, which flows in from the south, forms the frontier line between Servia and Bulgaria. Radujevac, the last of the Servian river-ports, is a small town and the station for Negotin, a town lying some few miles to the south, which latter is the centre of a large vineyard district that gives its name to a wine that is said to be particularly good; indeed the Negotin wine “is exported abroad in large quantities via Radujevac, and after being artificially treated, is often re-imported into Servia, in the guise of an expensive dessert wine.” Beyond Radujevac, before the frontier river, the Timok, is reached, are many remains of old Roman fortifications, reminiscent of the timid and fruitless precautions of Justinian which, said Gibbon, “expose to a philosophic eye the debility of the empire. From Belgrade to the Euxine, from the conflux of the Save to the mouth of the Danube, a chain of above four score fortified places was extended along the banks of the great river.” The broadening stream, broken up by many islands, turns south as it nears Widdin on the right, and Calafat on the left bank, places both of them associated with Russo-Turkish warfare. Widdin is an important town, and when occupied by the Turks, was strongly fortified. It stands on low, marshy ground, but in improving scenery, for behind in the distance are seen the rounded summits of a range of the Balkan mountains. The mosques and minarets, which it retains from the time when it was Turkish and the centre of an important pashalik, give it a picturesque appearance from the river.
