1. ODESSA on the Black Sea, 25 m. NE. of the mouth of the Dniester, is the fourth largest city of Russia, and the chief southern port and emporium of commerce. It exports large shipments of wheat, sugar, and wool; imports cotton, groceries, iron, and coal, and manufactures flour, tobacco, machinery, and leather. It is well fortified, and though many of the poor live in subterraneous caverns, is a fine city, with a university, a cathedral, and a publiclibrary. It was a freeport from 1817 till 1857. The population includes many Greeks and Jews.
