the rain or the
heat from injuring it from without, it should be smeared with clay and
bound with bark. It is customary to take off the scion of a vine three
days before it is to be grafted so that the superfluity of moisture
may drain out before the scion is inserted, or, if the graft is
already in place, an incision is made in the stock a little below the
graft from which the adventitious moisture may drain off: but this
is not done with figs and pomegranates, for in all trees of a
comparatively dry nature the graft is made immediately. Indeed, some
trees, like the fig, are best grafted when the scion is in bud.

Of the four kinds of propagation which I have discussed, that of
graftage is preferred in respect of those trees which, like the fig,
are slow in developing: for the natural seeds of the fig are those
grains seen in the fruit we eat and are so small as scarcely to be
capable of sprouting the slenderest shoots. For all seeds which are
small and hard are slow in germinating, while those which are soft are
more spontaneous, just as girls grow faster than boys. Thus by reason
of their feminine tenderness the fig, the pomegranate and the vine are
quicker to mature than the palm, the cypress and the olive, which are
rather dry than humid by nature. Wherefore we some times propagate
figs in nurseries from cuttings rather than attempt to raise them from
seed: unless there is no other way to secure them, as happens when one
wishes to send or receive seed across the sea. For this purpose the
ripe figs which we eat are strung together and when they have dried
out are packed and shipped wheresoever we wish, and thereafter being
planted in a nursery they germinate. In this way the Chian, the
Chalcidian, the Lydian, the African and other foreign varieties of
figs were imported into Italy.

For the same reason olives are usually propagated in nurseries from
truncheons such as I have described, rather than from its seed, which
is hard like a nut and slow to germinate.

_Of seeding alfalfa_

XLII. You should take care not to plant alfalfa[93] in soil which is
either too dry or half wet,[94] but in good order. The authorities say
that if the soil is in proper condition a _modius_ (peck) and a half
of alfalfa seed will suffice to sow a _jugerum_ of land. This seed is
sowed broad-cast on the land like grass and grain.

_Of seeding clover and cabbage_

XLIII. Snail clover (_cytisus_) and cabbage is sowed in beds well
