1911 Encyclopædia Britannica/Sologne
SOLOGNE (Secalaunia from Lat. secale, rye), a region of north-central France extending over portions of the department of Loiret, Loir-et-Cher and Cher. Its area is about 1800 sq. m., and its boundaries are, on the N. the river Loire, on the S. the Cher, on the E. the districts of Sancerre and Berry. The Sologne is watered by the Cosson and the Beuvron, tributaries of the Loire, and the Sauldre, an affluent of the Cher, all three having a west-south-westerly direction. The pools and marshes which are characteristic of the region are due to the impermeability of its soil, which is a mixture of sand and clay. The consequent unhealthiness of the climate has been greatly mitigated since the middle of the 19th century, when Napoleon III. led the way in the reclamation of swamps, the planting of pines and other trees and other improvements. Arable farming and stock-raising are fairly flourishing in the Sologne, but there is little manufacturing activity, the cloth manufacture of Romorantin being the chief industry. Game is abundant, and the region owes much of its revived prosperity to the creation. of large sporting estates.
