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mode of making credit answer the purposes of money, by which, when carried far enough, money may be very completely superseded, consists in making payments by checks. The custom of keeping the spare cash reserved for immediate use, or against contingent demands, in the hands of a banker, and making all payments, except small ones, by orders on bankers, is in this country spreading to a continually larger portion of the public. If the person making the payment and the person receiving it keep their money with the same banker, the payment takes place without any intervention of money, by the mere transfer of its amount in the banker’s books from the credit of the payer to that of the receiver. If all persons in [New York] kept their cash at the same banker’s, and made all their payments by means of checks, no money would be required or used for any transactions beginning and terminating in [New York]. This ideal limit is almost attained, in fact, so far as regards transactions between [wholesale] dealers. It is chiefly in the retail transactions between dealers and consumers, and in the payment of wages, that money or bank-notes now pass, and then only when the amounts are small. As for the merchants and larger dealers, they habitually make all payments in the course of their business by checks. They do not, however, all deal with the same banker, and, when A gives a check to B, B usually pays it not into the same but into some other bank. But the convenience of business has given birth to an arrangement which makes all the banking-houses of [a] city, for certain purposes, virtually one establishment. A banker does not send the checks which are paid into his banking-house to the banks on which they are drawn, and demand money for them. There is a building called the Clearing-House, to which every [member of the association] sends, each afternoon, all the checks on other bankers which he has received during the day, and they are there exchanged for the checks on him which have come into the hands of other bankers, the balances only being paid in money; or even these not in money, but in checks.
