Shortly beyond Silistria the Danube leaves Bulgarian territory, after which Rumania is on both sides of the stream, for the land on the right, the Dobrudja, extending from the Danube to the Black Sea, was awarded to Rumania by the Treaty of Berlin. Both sides, too, become flat alike. The river is still greatly diversified by islands covered with bushes and reeds--“more resembling a sea studded with innumerable islets than a river”--while the avi-fauna is particularly rich, immense flocks of wild swans, wild geese, pelicans, herons, and other waterfowl being often seen. Miss Skene described how, in journeying up the river, the steamer in which she travelled was compelled to moor hereabouts at night, in a wilderness by no means devoid of beauty. “We lay under a wooded bank with many little fairy islands around us, all covered with green bushes, whose very wildness and want of cultivation were their principal charm ... pelicans and storks stalking about on the lonely islands, uttering at times a wild cry, which more than anything I know brings most forcibly to the mind the images of solitude and desolation.” Through scenery thus indicated, the river continues for many miles of the northerly course which it takes beyond Silistria. About forty miles below that place a lengthy railway bridge--the only one below Belgrade--crosses the Danube, connecting Bukarest with the Black Sea port of Costantza (Kustendji), near to which place was Tomi, where Ovid spent his long years of exile. Before the bridge comes in sight an interesting relic of the Roman occupation is to be noted in the Wall of Trajan--a double rampart of earth, which runs from near the village of Rasova to Kustendji. The railway bridge, which crosses the main stream of the Danube and the Borcea arm, is over two and a half miles in length, and one of the most remarkable examples of this kind of engineering; it has sixty-eight spans, the longest of which--one of those over the main stream--is a cantilever over six hundred feet in length. When it is realized that the foundations of the piers are laid in water the mean depth of which is nearly a hundred feet at ordinary water level, and that the bridge is made at a height of more than one hundred and twenty feet at low water, to enable sailing ships to pass through unhindered, the boast that its completion is one of the greatest engineering feats of modern times will scarcely be regarded as an exaggeration. The bridge was completed and opened for traffic in 1895, having cost a sum of close upon a million and a half sterling.
