a river of Spain, which rises in a chasm called Corral de Veleta, on the N.W. slope of the Sierra Nevada, in Andalucia, province of Granada. It flows N.W. through the town of Granata, then W.S.W. till it reaches Loja, where it turns W.N.W., passes the town of Ejea, and joins the left bank of the Guadalquivir, at Palma del Rio, 32 miles below Cordova, after a course of nearly 160 miles. It is nowhere navigable; but it furnishes much valuable water-power, and is extensively used in irrigation.
