The opportunities opened for men to advance their fortunes in other parts of the world drained Italy of many of its most enterprising citizens. The grandsons of the yeomen who had held at bay Pyrrhus and Hannibal sold their farms and went away. The small holdings merged rapidly into large estates bought up by the Roman capitalists. At the final settlement of Italy, some millions of acres had been reserved to the State as public property. The "public land," as the reserved portion was called, had been leased on easy terms to families with political influence, and by lapse of time, by connivance and right of occupation, these families were beginning to regard their tenures as their private property, and to treat them as lords of manors in England have treated the "commons." Thus everywhere the small farmers were disappearing, and the soil of Italy was fast passing into the hands of a few territorial magnates, who, unfortunately (for it tended to aggravate the mischief), were enabled by another cause to turn their vast possessions to advantage. The conquest of the world had turned the flower of the defeated nations into slaves. The prisoners taken either after a battle or when cities surrendered unconditionally were bought up steadily by contractors who followed in the rear of the Roman armies. They were not ignorant like the negroes, but trained, useful, and often educated men, Asiatics, Greeks, Thracians, Gauls, and Spaniards, able at once to turn their hands to some form of skilled labor, either as clerks, mechanics, or farm-servants. The great landowners might have paused in their purchases had the alternative lain before them of letting their lands lie idle or of having freemen to cultivate them. It was otherwise when a resource so convenient and so abundant was opened at their feet. The wealthy Romans bought slaves by thousands. Some they employed in their workshops in the capital. Some they spread over their plantations, covering the country, it might be, with olive gardens and vineyards, swelling further the plethoric figures of their owners' incomes. It was convenient for the few, but less convenient for the Commonwealth. The strength of Rome was in her free citizens. Where a family of slaves was settled down, a village of freemen had disappeared; the material for the legions diminished; the dregs of the free population which remained behind crowded into Rome, without occupation except in politics, and with no property save in their votes, of course to become the clients of the millionaires, and to sell themselves to the highest bidders. With all his wealth there were but two things which the Roman noble could buy, political power and luxury; and in these directions his whole resources were expended. The elections, once pure, became matters of annual bargain between himself and his supporters. The once hardy, abstemious mode of living degenerated into grossness and sensuality.
