Meanwhile out in the country we can perceive the farm, with its hedges of quick-set, its stone walls, or its bank and ditch. The rather primitive plough--though not always so primitive as it was a generation or so ago in Italy--is being drawn by oxen, while, for the rest, there are in use nearly all the implements which were employed before the quite modern invention of machinery. It may be remarked at this point that the rotation of crops was well understood and regularly practised. Then there are the pasturelands, on the plains in the winter, but in summer on the hills, to which the herdsmen drive their cattle along certain drove-roads till they reach the unfenced domains belonging to the state. There they form a camp of huts or wigwams under a "head man," and surround their charges with strong fierce dogs, whose business it is to protect them, not only from thieves, but also from the wolves which were then common on the Apennines--where, indeed, bears also were to be met. There was no want of occupation in the country in the time of haymaking, of the vintage, or of olive-picking. Even the city unemployed could gather a bunch of grapes or pick an olive, just as they can with us, or just as the London hop-picker can take a holiday and earn a little money in Kent. In the vineyards, where the vines commonly trailed upon low elms and other trees, various vegetables grew between the rows, as they still do about Vesuvius; on the hills were olive-groves, which cost almost nothing to keep in order, and which supplied the "butter" and the lamp-oil of the Mediterranean world.
