The Jucar takes its rise not far from the sources of the Tagus, on the south side of the Muela de San Juan, which we have before mentioned as the culminating watershed of the peninsula. It flows first in a south-westerly direction as far as Cuenca, whence it gradually turns south and south-east, and at Jorquera, to the north-east of Albacete, strikes eastwards for the Mediterranean, which it finally enters at Cullera. Like the Segura and Guadalaviar, its waters are drained off for irrigation; but its basin is narrower, and it can boast of no fertility equal to the huertas of Murcia or Valencia. Its course is about 317 miles, the area of its bed 580, and the rainfall some twelve and a half inches; the irrigated land is over 30,000 acres. The Guadalaviar, or Turia, rises on the north side of the Muela de San Juan, and descending rapidly, flows eastward past Albarracin and Teruel; at which latter town it turns abruptly southwards till it enters the province of Valencia, where it again takes a more easterly course, flowing with ever-diminished stream through the rich garden of Valencia, at which city it falls into the Mediterranean, with water which, except in time of flood, scarcely rises above the ankle. The length of its course is about 187 miles, the area of its basin 320 square miles; it irrigates over 25,000 acres near Valencia. Besides these larger rivers, there are on the Mediterranean slope innumerable smaller streams, whose waters, though of little geographical importance, are of the greatest utility to agriculture. In summer scarcely a drop of their waters reaches the sea; all is either employed for irrigation, or dissipated by evaporation; often they are dammed up to form reservoirs or _pantanos_, sometimes employed for rice culture. But small as these streams are, it is to them that this burning coast owes its beauty and fertility, its almost tropical vegetation and its rich products. The fair gardens of Castellon, of Gandia, of Murviedro would be barren and valueless without these waters. Still farther to the north the waters of the Llobregat, and the canal of Urgel in Catalonia, are used for the same purpose.
