The main elements of their civilization came to the Greeks, and especially to the Greek cities in Asia Minor demonstrably from the Eastward; the Greek West proved itself quick to catch up the thoughts and the modes of the East; accordingly, Isocrates in his plea against the banker, Pasion, describes a formal bill of Exchange bought by Stratocles in Athens, payable in Pontus, and guaranteed principal and interest by Pasion; the practical Romans were pupils of the Greeks in all such matters, and so it came about in course of time, that Cicero wrote as follows in a letter to Atticus,—"Let me know, if the money my son needs at Athens can be sent him by way of exchange, or if it be necessary for it to be taken to him,—permutarine possit an ipsi ferendum sit"; and after that the Jews and the Lombards carried the Letter of Credit all over the world.

It goes without saying, when the most civilized and advanced people of the world were the first to adopt and have been since the quickest to expand the use of Credit, that there must be pretty obvious and very solid advantages from such use and expansion; and we must now note and weigh a few of these advantages.

(1) There are young men in every advanced community in the world who have integrity and industry and skill, but little or no Capital; and when such men are enabled to borrow money, as by the Scotch system of "cash accounts" or otherwise, to start themselves in business or to enlarge a business already in successful operation, the general interests of Production as well as their own personal interests, are greatly subserved by such credit; because in all probability much capital thus passes out of hands which are less into hands which are more able to use it productively. Those who are best able to make capital tell by increase are generally those who are most desirous to obtain it, and frequently those who can offer the best security for its replacement. Nothing, therefore, is to be said against, but everything in favor of, such a loaning of capital as shall bring it under safe conditions from the hands of the idle and the aged, from those indisposed or incompetent to use it productively, into other hands at once competent and honest. Such credits as these are a benefit and only a benefit to all the parties concerned, and to Society at large. The active operators retain something of profit after replacing the capital with current interest upon it; the lenders receive more than if their capital remained idle, or they employed it themselves; and Society is benefited by a more complete development, and rapid circulation, of Services. Despite all the instances of broken faith, it is still an honor to human nature, that men do so gain by good character the confidence of their fellows, that they are and ought to be trusted with capital on their simple word or note; and it is the glory of free political institutions, that under their influence more than elsewhere, young men do rise by the help of so slight a stepping-stone as this, in crowds, to the high places of opulence.

In the important point of view, that thus all of the available capital of a community is brought out into productive activity, too much can scarcely be said of Savings-Banks, which take the surplus earnings of the poor, and not only keep them safely, but pay a fair interest on each deposit, and loan the aggregate at a higher rate on choice securities, thus stimulating frugality in a wide circle of depositors, and at the same time aiding Production by opportune loans to the best class of borrowers. In the year 1881, there were $443,000,000 invested in savings-banks in the State of New York, and $230,000,000 in the small State of Massachusetts.

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.

(2) There is another class of advantages in Credit, which do not depend so much on the transfer of Capital from less to more productive hands, as on the facilities which credit affords in economizing the general operations of Exchange. Here the advantages are derived from the convenience of settling accounts arising out of exchanges, rather than from the character of the exchanges themselves. Look a moment, for example, at foreign Bills of Exchange. They serve to settle up the accounts arising from the Commerce of two or six Continents, with but little transmission of money from any, and with but very little loss of time. Commercial bills drawn in New York on London have been usually payable at sixty days' sight; the New York merchant despatching a ship is able to realize at once the value of her cargo, minus interest for the time his bill has to run; since bankers' bills have so largely taken the place of "commercial" bills, the time is much shortened thereby, and this is one reason why bankers' bills bear a higher price in the market; the merchant or sender is indeed still liable in part to see that his bill is ultimately paid by the drawee; but the commercial integrity of the leading houses and leading banks in all countries is with justice so firmly believed in and acted on, that on the whole but little anxiety springs from this source. It is one of the noble things in international commerce, that men trust each other across the oceans, and lay millions of value on the faith of a single firm.

Inland bills of exchange equally facilitate settlements within the country itself; and cheques, which are of the same essential nature as inland bills, contribute to the same end even more simply and surely, passing readily in payments wherever the parties are known, and through credit and set-off doing the work of money more conveniently and economically than, and within certain limits just as safely as, money itself could do it. The face of a cheque drawn to the amount of his deposit in favor of another depositor in the same bank is transferred in the banker's books from the credit of the drawer to that of the payee by the stroke of a pen, no money at all passes in the premises, while the banker is released from one debt by creating another of equal amount, the drawer is released from one debt by another to be transferred to the payee, and the payee is paid by the drawer by the former's receipt of another debt more acceptable to him.

(3) Besides the two essential functions of all banks, namely, the receiving of deposits and the discounting of bills, most of them perform a variety of other legitimate operations in Credit, which must be classed among the advantages of Credit. They buy and sell debts of all sorts. They make collection of debts for their customers. They sell their own drafts on distant places. Since 1863, our national banks have done an immense business in handling the debt of the United States: they were instrumental in diffusing the national bonds among all classes of the people: they collect for their customers the coupons at maturity: they have been and still are the factors of the government in exchanging, for those who desire it, one species of bond for another; and the entire debt of the United States has been several times changed, mainly through the agency of the banks, from bonds at high rates of interest and for short times of maturity to bonds at lower rates and for longer times.

(4) The fourth, and probably the chief, advantage of Credit is the fact, that a new purchasing-power is created by means of it, a new Valuable, something additional to all existing before in the world of Values. One can buy other things with Credit, as well as with material Commodities and personal Services. Credit, therefore, becomes a Salable under the two peculiar limitations already explained, those of future Time and personal Confidence, just as Commodities become a Salable under the peculiar limitations belonging to them; and, what is more to the present purpose, just as some Commodities (all of them salable) become Capital under the action of the abstinence of their owners, so some Credits (all of them salable) become Capital under the action of the Abstinence of their owners. Some commodities and some credits are expended, that is, sold, for the immediate gratification of their owners, without ever a thought of a future increase to accrue; but also, some commodities and credits are reserved by their owners for use in further production, that is, for future buying and selling; and the motive in all such cases is the same that creates all Capital everywhere, namely, the increase to accrue as the result of such abstinence; and, consequently, we lay down the postulate with all confidence, and enumerate it as one of the main advantages of Credit, that some Credits are Capital, with all the powers in production of that potent agent already exemplified.
