Another consequence of some moment arose out of this victory. The Athenians planted a body of four thousand of their citizens as klêruchs (lot-holders) or settlers upon the lands of the wealthy Chalkidian oligarchy called the Hippobotæ,—proprietors probably in the fertile plain of Lêlantum, between Chalkis and Eretria. This is a system which we shall find hereafter extensively followed out by the Athenians in the days of their power; partly with the view of providing for their poorer citizens,—partly to serve as garrison among a population either hostile or of doubtful fidelity. These Attic klêruchs (I can find no other name by which to speak of them) did not lose their birthright as Athenian citizens: they were not colonists in the Grecian sense, and they are known by a totally different name,—but they corresponded very nearly to the colonies formally planted out on the conquered lands by Rome. The increase of the poorer population was always more or less painfully felt in every Grecian city. For though the aggregate population never seems to have increased very fast, yet the multiplication of children in poor families caused the subdivision of the smaller lots of land, until at last they became insufficient for a maintenance; and the persons thus impoverished found it difficult to obtain subsistence in other ways, more especially as the labor for the richer classes was so much performed by imported slaves. Doubtless some families possessed of landed property became extinct; but this did not at all benefit the smaller and poorer proprietors; for the lands thus rendered vacant passed, not to them, but by inheritance, or bequest, or intermarriage, to other proprietors, for the most part in easy circumstances,—since one opulent family usually intermarried with another. I shall enter more fully at a future opportunity into this question,—the great and serious problem of population, as it affected the Greek communities generally, and as it was dealt with in theory by the powerful minds of Plato and Aristotle. At present it is sufficient to notice that the numerous klêruchies sent out by Athens, of which this to Eubœa was the first, arose in a great measure out of the multiplication of the poorer population, which her extended power was employed in providing for. Her subsequent proceedings with a view to the same object will not be always found so justifiable as this now before us, which grew naturally, according to the ideas of the time, out of her success against the Chalkidians.
