The art of wealth-getting which consists in household management, on the one hand, has a limit; the unlimited acquisition of wealth is not its business.

Wherefore, in all wise states, if there is want of pure water, and the supply is not all equally good, the drinking water ought to be separated from that which is used for other purposes.
