Fragments and life in Müller, _Frag. Hist. Graec._, vol. iii.; see also Sevin, _Mém. de l'Acad. des Inscriptions_, vol. iv.; Hullemann, _De vita et scriptis Jubae_ (1846). For the denarii of Juba II. found in 1908 at El Ksar on the coast of Morocco see Dieudonné in _Revue Numism_. (1908), pp. 350 seq. They are interesting mainly as throwing light on the chronology of the reign. JUBA, or JUB, a river of East Africa, exceeding 1000 m. in length, rising on the S.E. border of the Abyssinian highlands and flowing S. across the Galla and Somali countries to the sea. It is formed by the junction of three streams, all having their source in the mountain range N.E. of Lake Rudolf which is the water-parting between the Nile basin and the rivers flowing to the Indian Ocean. Of the three headstreams, the Web, the Ganale and the Daua, the Ganale (or Ganana) is the central river and the true upper course of the Juba. It has two chief branches, the Black and the Great Ganale. The last-named, the most remote source of the river, rises in 7° 30´ N., 38° E. at an altitude of about 7500 ft., the crest of the mountains reaching another 2500 ft. In its upper course it flows over a rocky bed with a swift current and many rapids. The banks are clothed with dense jungle and the hills beyond with thorn-bush. Lower down the river has formed a narrow valley, 1500 to 2000 ft. below the general level of the country. Leaving the higher mountains in about 5° 15´ N., 40° E., the Ganale enters a large slightly undulating grass plain which extends south of the valley of the Daua and occupies all the country eastward to the junction of the two rivers. In this plain the Ganale makes a semicircular sweep northward before resuming its general S.-E. course. East of 42° E. in 4° 12´ N. it is joined by the Web on the left or eastern bank, and about 10 m. lower down the Daua enters on the right bank.
