ARDECHE  , an inland

department of south-eastern France, formed in 1790 from the Vivarais, a district of Languedoc . Pop . (1906) 347,140 . Area, 2145 sq. m . It is bounded N.W. by the department of Loire, E. by the Rhone which divides it from Isere and DrOme, S. by Gard and W. by Lozere and Haute-Loire . The surface of Ardeche is almost entirely covered by the Cevennes mountains, the main chain, continued in the Boutieres mountains, forming its western boundary . Its centre is traversed from south-east to north-west by the Coiron range which extends from the Rhone to the Mont Mezenc (5755 ft.), the highest point in the department, and the oldest of its many volcanoes . These mountains separate the southern half of the department, which comprises the basin of the Ardeche, from the northern half which is watered by numerous smaller tributaries of the Rhone, the chief of which are the Erieux and the Doux . A few rivers belong to the Atlantic side of the watershed, the chief being the Loire, which rises on the western borders of the department, and the Allier, which for a short distance separates it from Lozere . Nearly all the rivers of the department are of torrential swiftness and subject to sudden floods . The scenery through which they flow is often of great beauty and grandeur . Natural curiosities are the Pont d'Arc, over the Ardeche, and the Chaussee des Geants, near Vals .

The

climate in the valley of the Rhone is, in general, warm, and sometimes very hot; but westward, as the elevation increases, the cold becomes more intense and the winters longer . Some districts, especially in summer, are liable to sudden alterations in the temperature . Rye, wheat and potatoes are the chief crops cultivated . Good red and white wines are grown in the hilly region bordering the Rhone valley, the white wine of St Peray being highly esteemed . The principal fruits are the chestnut, which is largely exported, the olive and the walnut . In the rearing of silk-worms, Ardeche ranks second to Gard among French departments, and great numbers of mulberry trees are grown for the purposes of this industry . The many goats and sheep of Ardeche make it one of the chief sources of supply of skins for glove-making . Mines of coal, iron, lead and zinc are worked, and the quarries furnish hydraulic lime (Le Teil) and other products . Besides flour-mills, distilleries and saw-mills, there are important silk-mills and leather-works and paper-factories . Annonay is the principal industrial town . The department exports wine, cattle, lime, mineral waters, silk, paper, &c . Hot springs are numerous, and some of them, as those of Vals, St Laurent-les-Bains, Celles and Neyrac, are largely resorted to .
