THE DANUBE (Ger., Donau), one of the most important rivers of Europe, and next to the Volga the largest, originates in two small streams rising in the Schwarzwald, or Black Forest, in Baden, Germany, and uniting at Donaueschingen, two thousand two hundred and sixty-four feet above sea level. The Germans occupy the entire upper basin, and portions of the middle and lower; the Slavs parts of both banks of the middle course; the Magyars the central portion of the valley; and the Roumanians the lower regions.

GENERAL COURSE OF THE
GERMAN DANUBE

The river flows first southeast and then northeast to Ulm, one thousand, five hundred and nineteen feet above sea level. At Regensburg it reaches its most northerly point, and from thence its course is generally southeast. Between Regensburg and Vienna the banks of the river are frequently remarkable for their romantic beauty. At Tuttlingen it contracts and the hills crowd close to the banks, while ruins of castles crown almost every possible summit. The scenery is wild and beautiful until the river passes Sigmaringen.

THE AUSTRIAN DANUBE, FAMED
IN HISTORY AND SONG

From Passau the Danube flows through Austria for a distance of two hundred and thirty-three miles. Closed in by mountains it flows past Linz in an unbroken stream; below, it expands and divides into many arms until it reaches the famous whirlpool near Grein, where its waters unite and flow on in one channel for forty miles through mountains and narrow passes. Between Linz and Vienna it is renowned not only for its picturesque beauty, but for the numerous historic buildings and ruins which crown its banks. The splendid Benedictine monastery of Melk, the ruins of Durrenstein, and the prison of Richard the Lion-hearted are among the most interesting.

Vienna, to defend the city against risk of inundation, the course of the Danube skirting it was, in 1868-81, diverted into an artificial channel. Similar works have been undertaken near Budapesth, in Hungary.

FROM VIENNA TO
THE IRON GATE

After passing Vienna and Marchfeld, the river cuts through a defile formed by the lower spurs of the Alps and Carpathians and enters Hungary at the ruined castle of Theben, a little above Pressburg, the old Magyar capital. Here, again, it gives off a number of branches, forming a labyrinth of islands known as Schütten, but on emerging it flows uninterruptedly southward through wide plains interspersed with pools, marshes, and sandy wastes. The principal affluents here are the Save, the Drave, and the Theiss.

Sixty miles before entering Roumania the river passes through a succession of rapids or cataracts which it has made in cutting a passage for itself through the cross chain of hills which connect the Carpathian Mountains with the Alps. The last of these cataracts, at Old Orsova, is called the Iron Gate. Between 1878 and 1898, the Hungarian government carried through, at a cost of seven million five hundred thousand dollars, extensive engineering works at the gorges of the Iron Gates for deepening the channel and cutting a canal.
