GUADALQUIVIR (Arab. the great river; ane. Bae(is), the most impor tant river of Spain, for the mass of waters which it conveys to the ocean, and for the extent of its natural navigation; has its origin in the Sierra Cazorla, near the eastern border of the, province of Jean; flows in a general s.w. direction through the provinces of Jean, Cordova, Sevilla; and forming the boundary for about ten miles between the provinces of Huelva and Cadiz, falls into the Atlantic at San Tamar de Earrameda, after a course of about 300 miles. The principal towns upon its banks are Montoro, Cordova, and Sevilla, to the last of which, about 80 m. above its mouth, the river is navigable. Below Sevilla it twice divides itself into two branches, forming two islands—the Isla Menor and the Isla Mayor. Its chief affluents are the Gadajos and the Jenil on the left, and the Guadalimar and the Guadiato on the right. The lower course of the Guadal
quivir is sluggish and dreary in the highest degree; the stream itself is turbid and muddy, and eats its way through an alluvial level given up to herds of cattle and to aquatic fowls. There are no villages in this district, which, though favorable to animal and vegetable life, is fatal to man, from the ague and fever caused by the numerous swamps. There is no great trade on the Guadalquivir; foreign vessels are generally moored at the Isla Menor, and their cargoes sent up to Sevilla by means of barges.
a river of North America, rises in the southern section of the state of Texas, and flows in a south-eastern direction, emptying its waters into Espiritu Santo Bay, after a course estimated at about 250 miles. The geography of this stream and its capabilities are not yet well-known.
