This great southern plain of Rumania is monotonous in its features. It slopes gently upwards from the Danube to the Car pathians and is intersected by a succession of rivers which, like the Dambovita, the Oltu and the Teleorman, rise on the southern and south-eastern slopes of the mountains and flow without much deviation into the Danube. Passage from east to west is thus much hindered and interrupted.
largest and longest river of Transylvania. It forms the northern boundary of the Banat province, which is traversed also by some minor streams. This province forms the plain-land end of the gradually sloping plateau of Transylvania so that a traveller going from the Carpathian passes to the Theiss would on the whole be steadily descending. It is structurally part of the main Hungarian plain but historically and ethnically is a unity. It is rich, well watered and fertile, and in its southern corner, where it extends to the Danube, richly endowed with coal and other minerals. Central Transylvania produces gold in small quantities, but is mainly agricultural farmland. Fruit and vines, maize, wheat and rye are largely grown. Crops of hemp, flax and tobacco are also gathered though not in large quantities. Bears, wolves, foxes and boars are found in the abundant forests of the uplands. The goldmines are situated, as in antiquity, in the isolated mass of hills in the region of Kluj, in particular at Verespatak and in the mountains of Hunedoara, near Deva. In 590o the value of gold so obtained was i300,000. The gold is often found in combina tion with tellurium. Saline springs are common and salt is worked at Maros-Ujvar, Des-Akna-Kolozs, Torda and Vizakna. Of the 337,996 tons of salt obtained by the state monopoly in 1925 the bulk comes from these sources.
The Danube is a controlling feature in the life of the country. It first meets the Rumanian frontier at the Iron Gates and thence flows with a swift and deep stream to Kalafat. Here, taking a sharp turn eastwards it flows through open country with cliff banks on the Bulgarian side, and lagoons and marshes on the Rumanian. It gradually gains in width and volume but decreases in speed. It so runs without change, always with low hills on the south bank until Turnu Magurele and Giurgiu are reached. Islands are common throughout the later reaches. After Giurgiu the direction is north-east by east and the river opens out by Silistra into a maze of islands, shoals and sandbanks. At Giurgiu and Silistra are the two most important ferries. From Calarasi onwards the river has great width. It is bridged at Cernavoda by a bridge some 12 km. in length and this is the average width of the river for many miles. Near Braila and Galatz it widens still more and after its final sharp turn to the east at Galatz the Delta proper begins. The principal channel cuts through the centre of the Delta from Tulcea and enters the sea at Sulina. It is kept clear largely by dredging. There is no bridge over the Danube between Novisad in Yugoslavia and the sea except at Cernavoda.
