(cf. p. 222), and why capital flows readily in that direction.
It is chiefly in the latter form [promissory notes] that it has become, in commercial countries, an express occupation to issue such substitutes for money. Dealers in money wish to lend, not their capital merely, but their credit, and not only such portion of their credit as consists of funds actually deposited with them, but their power of obtaining credit from the public generally, so far as they think they can safely employ it. This is done in a very convenient manner by lending their own promissory notes payable to bearer on demand—the borrower being willing to accept these as so much money, because the credit of the lender makes other people willingly receive them on the same footing, in purchases or other payments. These notes, therefore, perform all the functions of currency, and render an equivalent amount of money, which was previously in circulation, unnecessary. As, however, being payable on demand, they may be at any time returned on the issuer, and money demanded for them, he must, on pain of bankruptcy, keep by him as much money as will enable him to meet any claims of that sort which can be expected to occur within the time necessary for providing himself with more; and prudence also requires that he should not attempt to issue notes beyond the amount which experience shows can remain in circulation without being presented for payment.
The convenience of this mode of (as it were) coining credit having once been discovered, governments have availed themselves of the same expedient, and have issued their own promissory notes in payment of their expenses; a resource the more useful, because it is the only mode in which they are able to borrow money without paying interest.
§ 6. Deposits and Checks.
A fourth mode of making credit answer the purposes of money, by which, when carried far enough, money [pg 333] may be very completely superseded, consists in making payments by checks. The
