Or Euxine, an inland sea, lying between Europe and Asia, twice the size of Britain, being 700 m. in greatest length and 400 m. in greatest breadth; communicates in the N. with the Sea of Azov, and in the SW., through the Bosphorus, the Sea of Marmora, and the Dardanelles, with the Mediterranean. It washes the shores of Turkey, Rumelia, Bulgaria, Russia, and Asia Minor; receives the waters of the Danube, Dneister, Bug, and Don, from Europe, and the Kizil-Irmak and Sakaria from Asia—three times as much as is received by the Mediterranean. It has but one island, Adassi, off the mouths of the Danube; no reefs or shoals; hence in summer navigation is very safe. In winter it is harassed by severe storms. Among the chief ports are Odessa, Kherson, Batoum, Trebizond, and Sinope; the first two are ice-bound in January and February. For three centuries the Turks excluded all other nations from its waters; but the Russians (1774), Austrians (1784), French and English (1802) secured trading rights. Russia and Turkey keep fleets in it, but other warships are excluded. Its waters are fresher than those of the ocean, and it has no noticeable tides.
