Although it is mentioned in the 16th century, and coal was discovered there at the time of Peter the Great, it was not until r795 that an Englishman, Gascoyne or Gaskoin, established its first iron-works for supplying the Black Sea fleet and the southern fortresses with guns and shot . This proved ,a failure, owing to the great distance from the sea; but during the Crimean War the iron-works of Lugan again produced shot, shell and gun-carriages . Since 1864 agricultural implements, steam-engines, and machinery for beetroot sugar-works, distilleries, &c., have been the chief manufactures . There is an active trade in cattle, tallow, wools, skins, linseed, wine, corn and manufactured wares .
