set in action and maintained, that it would need a war with some great sea-power to convince us that London or Glasgow might, under certain untoward circumstances, be starved; and as our attention has never been drawn to the details of food-supply, we do not readily see why there should have been any such difficulty at Rome as to call for the intervention of the State.  Perhaps the best way to realise the problem is to reflect that every adult inhabitant needed about four and a half pecks of corn per month, or some three pounds a day; so that if the population of Rome be taken at half a million in Cicero’s time, a million and a half pounds would be demanded as the daily consumption of the people.[55] I have already said that in the last three centuries B.C. there was a universal tendency to leave the country for the towns; and we now know that many other cities besides Rome not only felt the same difficulty, but actually used the same remedy—­State importation of cheap corn.[56] Even comparatively small cities like Dyrrhachium and Apollonia in Epirus, as Caesar tells us while narrating his own difficulty in feeding his army there, used for the most part imported corn.[57] And we must remember that while some of the greatest cities on the Mediterranean, such as Alexandria and Antioch, were within easy reach of vast corn-fields, this was not the case with Rome.  Either she must organise her corn-supply on a secure basis, or get rid of her swarms of poor inhabitants; the latter alternative might have been possible if she had been willing to let them starve, but probably in no other way.  To attempt to put them out upon the land again was hopeless; they knew nothing of agriculture, and were unused to manual labour, which they despised.

Thus ever since Rome had been a city of any size it had been the duty of the plebeian aediles to see that it was adequately supplied with corn, and in times of dearth or other difficulty these magistrates had to take special measures to procure it.  With a population steadily rising since the war with Hannibal, and after the acquisition of two corn-growing provinces, to which Africa was added in 146 B.C., it was natural that they should turn their attention more closely to the resources of these; and now the provincial governors had to see that the necessary amount of corn was furnished from these provinces at a fixed price, and that a low one.[58] In 123 B.C.  Gaius Gracchus took the matter in hand, and made it a part of his whole far-reaching political scheme.  The plebs urbana had become a very awkward element in the calculations of a statesman, and to have it in a state of starvation, or even fearing such a state, was dangerous in the extreme, as every Roman statesman had to learn in the course of the two following centuries.  The aediles, we may guess, were quite unequal to the work demanded of them; and at times victorious provincial governors would bring home great quantities of corn and give it away gratis for their private purposes,
