In this first category of the advantages of Credit, come also the ordinary bank discounts, made for short periods only, holding the debtor to the strictest rules of payment, only professing and only enabled to help customers over the transient hard places in their business, and _not_ to furnish the funds on which the business is mainly conducted. Loans drawn from the banks on interest should never be put into the form of fixed capital, and should only be a _part_ of the quick or circulating capital, since only the passing necessities of a business having an independent basis and movement of its own, can safely be met by bank discounts. The cash credits of Scotland are quite different both in what they are and in what they imply from the short and sharp discounts of the banks of our own country. So far as the capital stock of banks is made up, as it usually is, of a large number of comparatively small subscriptions, there is the great advantage just spoken of, of calling a multitude of otherwise idle sums into activity in production; and so far as no undue privileges, unjust to other corporations and individuals, are accorded to banks by law, there is no branch of industry more legitimate and beneficial than banking. It is no essential part of the functions of a bank, that it manufacture and issue paper money; that feature is always rather a source of weakness than a ground of strength; the money the bank circulates should always be the national money; and if that too, unfortunately, should be credit-money, the element of credit in the _money_ should be sharply discriminated in the public mind from that other and quite different element of credit by which the bank _loans_ it to its customers.
