the need of regulating the Nile's overflow in Egypt, and the model and influence of the Roman empire in Mohammedan and Christian Europe. The city enables men to coöperate easily. In it ideas and feelings spread quickly. Life, property, and privileges are there protected by walls, and, if need be, by street barricades. "Two voices are there," wrote Wordsworth in 1807, his vision limited by the peril of England and Switzerland,-- "one is of the sea, One of the mountains; each a mighty Voice: In both from age to age thou didst rejoice, They were thy chosen music, Liberty." The voice of a city mob--that of Rome, Alexandria, Constantinople, Florence, or Paris, for example--was generally raucous and often cruel. But it made tyrants tremble and limited absolutism when the fear of assassination was powerless. Fortunately, it is not with the origins, but with the characteristics, of the Greek city-states that we have to do mainly when we seek to discover the grounds of their hatred of all imperialistic projects. Let us, therefore, try to form a concrete impression of the salient features of the hundreds of little states with which the progressive parts of Greece were honeycombed at the beginning of the classic period, in the sixth century B.C. Each political cell, so to speak, had its nucleus in a walled town and its substance in a small circuit of grain, pasture, and garden land which the inhabitants of the town owned and cultivated. Most of the towns were simply hives of farmers. Whether the farmers were landlords, small proprietors, or peasants; however much they were divided by lines of social cleavage, they were all able to meet on the common ground of a single occupation. And every day from March to November, from the out-cropping of the grass and foliage in the spring, through the season of the grain harvest, the vintage, and the picking of the olives, to the fall planting and seeding, the ebb and flow of agricultural life carried the population of the city to the country in the morning and back to the city again in the evening.
