Theiss (Tice; Hun. Tisza), the chief river of Hungary, rises by two streams, the Black Theiss and the White Theiss, in the Carpathians, and winds 750 miles NW., SW., and S., joining the Danube after running parallel to it for 300 miles. The Theiss has several large and navigable affluents, as the Maros and Bodrog.
