Sericulture is an important industry.
Sericulture is taught in a number of special schools and in a great number of village schools.
The district produces wheat, maize, barley and tobacco; sericulture and viticulture are both practised on a limited scale.
Sericulture, formerly a flourishing industry, has declined owing to a disease of the silk-worms, but efforts have been made to revive it.
It has a cathedral, being an archiepiscopal see of the Orthodox Greek Church, a school of gardening and sericulture, a public library, and a few distilleries, tanneries and oil works.
