labor is hired for this purpose at a
fixed daily wage. It is generally the
work of boys, girls, or young women,

may be able to alleviate their need.
But if, before or even after that
weeding, the multitude of remaining
herbs overcomes the field, the only
remedy, until all other roots die, is
repeated plowing and the restoration
of the sowing, and by these two
methods the farmer, according to
Columella, Combs it and exterminates
the herb increasing in the furrows.
