These the merchants pay away to the manufacturers for goods, the manufacturers to the farmers for materials and provisions, the farmers to their landlords for rent; the landlords repay them to the merchants for the conveniencies and luxuries with which they supply them, and the merchants again return them to the banks, in order to balance their cash accounts, or to replace what they my have borrowed of them; and thus almost the whole money business of the country is transacted by means of them.
