of the earlier cultivation obtain a very considerable increase,
especially of the gross produce--and beyond doubt the farmers of
this period drew a larger produce from their lands than the great
landholders of the later republic and the empire obtained (iii.
Latium); but moderation must be exercised in forming such estimates,
because we have to deal with a question of averages and with a mode
of husbandry conducted neither methodically nor with large capital.
The assumption of a tenfold instead of a fivefold return will be
the utmost limit, and yet it is far from sufficing. In no case
can the enormous deficit, which is left even according to those
estimates between the produce of the -heredium- and the requirements
of the household, be covered by mere superiority of cultivation.
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,
