RALPH: So husbandry was the management of the house, and because early modern economies were almost totally agricultural, it often meant cultivating the land and raising livestock. That sense continues today in the phrase, "animal husbandry".

SARAH: In Shakespeare's time, the word often had a connotation of managing the household finances, being thrifty; and that's the sense in which it is used here.
