Summary

| override_editor Encyclopædia Britannica, Ninth Edition…

The grain crop suffices only for a few months' local consumption; but olive oil of good quality is produced to the extent of 30,000 to 50,000 barrels per annum; the vineyards (in the west especially) yield 100,000 barrels of red wine (bought mainly by Rouen, Cette, Trieste, and Venice) ; the currant, introduced about 1859, has gradually come to be the principal source of wealth (the crop averaging 2,500,000 ℔) ; and small quantities of cotton, flax, tobacco, valonia, &c., are also grown. The salt trade, formerly of importance, has suffered from Greek customs regulations.
