C)4 THEFARMERS HI for export. Agriculture, improved by specialization and by certain, though late and modest, attempts of intensification, and thus enabled to survive periods of reduced trade and export, was on the whole saved by trade. The main producers for export were, of course, the larger estates, but it must have been useful and even essential for the small farmer, that, poor as he was, he could always make some money from part of his pro- duce. In consequence Attic agriculture did not perish during the Hellenistic Age; it even experienced a kind of revival during the second century B.C.1 Although Athens lost her pre-eminence as a centre of trade and industry, she lived on, though enfeebled, for two reasons: because of the Peiraeus where corn was always imported, even when later the harbour was no longer a centre of international commerce, and because of Attic agriculture which even attained a new degree of prosperity. 1 W. S. Ferguson, Hellenistic Athens^ 207, 231!*, emphasizes the new and considerable importance of the rural part of Attica, the 'Mesogaia', in the second century B.C.
