From the countries situated on the Bosporos and the Black Sea, Greece imported numerous valuable commodities, among which the principal were corn,[1964] salt-meat,[1965] and fish,[1966]—as thunnies, corduli, turbots, the kolias, a kind of mackerel, Tethæan oysters from Chalcedon, amiæ,[1967] mullets,[1968] sturgeons, oxyrunchi,[1969] coracini, skates, herrings,[1970] crabs,[1971] and the edible mussel.[1972] The way in which some of these fish were caught in the Euxine is perhaps worth describing:[1973] the natives pitching, in winter, their tents on the ice,[1974] cut therein large open spaces, towards which the fish thronging to enjoy the light, were taken in great numbers. ----- Footnote 1964: Demosth. adv.
