SPOLETO, a delegation of the Papal States, bounded on the N. by those of Perugia and Camerino, E. by that of Ascoli and the kingdom of Naples, S. by the delegation of Rieti, and W. by that of Viterbo; area, 1130 square miles. The eastern part of the country is occupied by the central chain of the Apennines, including the two loftiest peaks within the Papal dominions; Monte della Sibilla (7300 feet), and Monte Vittore (8130 feet). Various branches of this main ridge extend towards the west, and the delegation is thus, as a whole, mountainous. The greater part of the country is watered by affluents of the Tiber; but a small portion, east of the water-sheds of the Apennines, sends its waters into the Adriatic by the Tronto. On the west, the Maroggia flows northwards and joins the Topino, an affluent of the Tiber; and the Nera, a little to the east of the former river, flows southwards and falls into the Tiber. Between these two rivers rises a ridge called the Mountains of Somma. The valley of the Maroggia is the most fertile part of the whole country; it produces in abundance maize, wheat, pulse, wine, oil, and various fruits. The forests afford much valuable timber. Large numbers of cattle are reared, and much cheese is made. Among the minerals of the country are limestone, marble, gypsum, and potter's clay. Hardly any manufactures or trade are carried on here.
