The inhabitants are principally devoted to agriculture, and most of the arable land is cultivated. The mountains are terraced; and the old pine woods have in many places given way to the olive, the vine and the almond tree, to fields of wheat and flax, or to orchards of figs and oranges. For the last-mentioned fruits the valley of Sóller is one of the most important districts, the produce being largely transmitted to France. The yield of oil is very considerable, and Inca is the centre of the oil district. The wines are light but excellent, especially the Muscadel and Montona. During the summer there is often great scarcity of water; but, according to a system handed down by the Moors, the rains of autumn and winter are collected in enormous reservoirs, which contain sufficient water to last through the dry season; and on the payment of a certain rate, each landholder has his fields flooded at certain intervals. Mules are used in the agriculture and traffic of the island. The cattle are small, but the sheep are large and well fleeced. Pigs are reared for export to Barcelona, and there is abundance of poultry and small game. Brandy is made and exported in large quantities. Excellent woollen and linen cloths are woven; the silkworm is reared and its produce manufactured; and canvas, rope and cord are largely made, from both native and foreign materials. The roads are excellent, the four principal being those from Alcudia, Manacor, Sóller and Andraitx to the capital. Forty-eight miles of railway were open at the beginning of the 20th century. The main line runs from Palma to Manacor and Alcudia. The telegraphic system is fairly complete, and there is regular steam communication with Barcelona and Alicante. The principal towns include--besides Palma (63,937), Felanitx (11,294) and Manacor (12,408), which are described in separate articles--Andraitx (6516), Inca (7579), Llummayor (8859), Pollensa (8308), Santañy (6692) and Sóller (8026).
