oultry, and pigeons were kept in the farmyard, and fed as
there was need; and, where opportunity offered, a small hare-preserve
and a fish-pond were constructed--the modest commencement of that
nursing and rearing of game and fish which was afterwards prosecuted
to so enormous an extent.

Means of Husbandry
Cattle

The labours of the field were performed by means of oxen which were
employed for ploughing, and of asses, which were used specially for
the carriage of manure and for driving the mill; perhaps a horse also
was kept, apparently for the use of the master. These animals were
not reared on the estate, but were purchased; oxen and horses at least
were generally castrated. Cato assigns to an estate of 100 -jugera-
one, to one of 240 -jugera- three, yoke of oxen; a later writer on
agriculture, Saserna, assigns two yoke to the 200 -jugera-. Three
asses were, according to Cato's estimate, required for the smaller,
and four for the larger, estate.

Slaves

The human labour on the farm was regularly performed by slaves. At
the head of the body of slaves on the estate (-familia rustica-) stood
the steward (-vilicus-, from -villa-), who received and expended,
bought and sold, went to obtain the instructions of the landlord, and
in his absence issued orders and administered punishment. Under him
were placed the stewardess (-vilica-) who took charge of the house,
kitchen and larder, poultry-yard and dovecot: a number of ploughmen
(-bubulci-) and common serfs, an ass-driver, a swineherd, and, where a
flock of sheep was kept, a shepherd. The number, of course, varied
according to the method of husbandry pursued. An arable estate of 200
-jugera- without orchards was estimated to require two ploughmen and
six serfs: a similar estate with two orchards two plough-men and nine
serfs; an estate of 240 -jugera- with olive plantations and sheep,
three ploughmen, five serfs, and three herdsmen. A vineyard naturally
required a larger expenditure of labour: an estate of 100 -jugera-
with vine-plantations was supplied with one ploughman, eleven serfs,
and two herdsmen. The steward of course occupied a freer position
than the other slaves: the treatise of Mago advised that he should be
allowed to marry, to rear children, and to have funds of his own, and
Cato advises that he should be married to the stewardess; he alone had
some prospect, in the event of good behaviour, of obtaining liberty
from his master. In other respec
