In fact the counter-proof can only be regarded as successful, when it shall have produced a methodical calculation based on rural economics, according to which among a population chiefly subsisting on vegetables the produce of a piece of land of an acre and a quarter proves sufficient on an average for the subsistence of a family. It is indeed asserted that instances occur even in historical times of colonies founded with allotments of two -jugera-; but the only instance of the kind (Liv. iv. 47) is that of the colony of Labici in the year 336--an instance, which will certainly not be reckoned (by such scholars as are worth the arguing with) to belong to the class of traditions that are trustworthy in their historical details, and which is beset by other very serious difficulties (see book ii. ch. 5, note). It is no doubt true that in the non-colonial assignation of land to the burgesses collectively (-adsignatio viritana-) sometimes only a few -jugera- were granted (as e. g. Liv. viii. ii, 21). In these cases however it was the intention not to create new farms with the allotments, but rather, as a rule, to add to the existing farms new parcels from the conquered lands (comp. C. I. L. i. p. 88). At any rate, any supposition is better than a hypothesis which requires us to believe as it were in a miraculous multiplication of the food of the Roman household. The Roman farmers were far less modest in their requirements than their historiographers; they themselves conceived that they could not subsist even on allotments of seven -jugera- or a produce of one hundred and forty -modii-. 7.
