Our author then proceeds to his rules, many of which are sufficiently obvious. Thus, he advises, that when one is about to purchase a farm, he should examine if the climate, soil, and exposure be good: he should see that it can be easily supplied with plenty of water,—that it lies in the neighbourhood of a town,—and near a navigable river, or the sea. The directions for ascertaining the quality of the land are not quite so clear or self-evident. He recommends the choice of a farm where there are few implements of labour, as this shews the soil to be easily cultivated; and where there are, on the other hand, a number of casks and vessels, which testify an abundant produce. With regard to the best way of laying out a farm when it is purchased, supposing it to be one of a hundred acres, the most profitable thing is a vineyard; next, a garden, that can be watered; then a willow grove; 4th, an olive plantation; 5th, meadow-ground; 6th, corn fields; and, lastly, forest trees and brushwood. Varro cites this passage, but he gives the preference to meadows: These required little expense; and, by his time, the culture of vines had so much increased in Italy, and such a quantity of foreign wine was imported, that vineyards had become less valuable than in the days of the Censor. Columella, however, agrees with Cato: He successively compares the profits accruing from meadows, pasture, trees, and corn, with those of vineyards; and, on an estimate, prefers the last. When a farm has been purchased, the new proprietor should perambulate the fields the day he arrives, or, if he cannot do so, on the day after, for the purpose of seeing what has been done, and what remains to be accomplished. Rules are given for the most assiduous employment without doors, and the most rigid economy within. When a servant is sick he will require less food. All the old oxen and the cattle of delicate frame, the old wagons, and old implements of husbandry, are to be sold off. The sordid parsimony of the Censor leads him to direct, that a provident _paterfamilias_ should sell such of his slaves as are aged and infirm; a recommendation which has drawn down on him the well-merited indignation of Plutarch(17). These are some of the duties of the master; and there follows a curious detail of the qualifications and duties of the _villicus_, or overseer, who, in particular, is prohibited from the exercise of religious rites, and consultation of augurs.
