its treasonable relations with Hannibal, the suitability of the latter for grazing purposes, which had early made it the largest tract of land in Italy patrolled by the shepherd slave,[190] had swept village and cultivator away, and left through whole day's journeys but vast stretches of pasture between the decaying towns. For barrenness and desolation were often the results of the new and improved system of management. There were tracts of country which could not produce cereals of an abundance and quality capable of competing with the corn imported from the provinces; but even on territories where crops could be reared productively, it was tempting to substitute for the arduous processes of sowing and reaping the cheaper and easier industry of the pasturage of flocks. We do not know the extent to which arable land in fair condition was deliberately turned into pasturage; but we can imagine many cases in which the land recently acquired by capitalists, whether from the State or from smaller holders, was in such a condition, either from an initial lack of cultivation or from neglect or from the ravages of war, that the new proprietor may well have shrunk from the doubtful enterprise of sinking his capital in the soil, for the purpose of testing its productive qualities. In such cases it was tempting to treat the great domain as a sheep-walk or cattle-ranch. The initial expenses of preparation were small, the labour to be employed was reduced to a minimum, the returns in proportion to the expenses were probably far larger than could be gained from corn, even when grown under the most favourable conditions. The great difficulty in the way of cattle-rearing on a large scale in earlier times had been the treatment of the flocks and herds during the winter months. The necessity for providing stalls and fodder for this period must have caused the proprietor to limit the heads of cattle which he cared to possess. But this constraint had vanished at once when a stretch of warm coast-line could be found, on which the flocks could pasture without feeling the rigour of the winter season. Conversely, the cattle-rearer who possessed the advantage of such a line of coast would feel his difficulties beginning when the summer months approached. The plains of the Campagna and Apulia could have been good neither for man nor beast during the torrid season. The full condition which freed a grazier from all embarrassment and rendered him careless of limiting the size of his flocks, was the combined possession of pastures by the sea for winter use, and of glades in the hills for pasturage in summer.[191] Neither the men of the hills nor the men of the plains, as long as they formed independent communities, could become graziers on an extensive scale, and it has been pointed out that even a Greek settlement of the extent of Sybaris had been forced to import its wool from the Black Sea through Miletus.[192] But when Rome had won the Apennines and extended her
