As the notes discounted have usually but a short time to run,--say three months on an average,--the bank notes issued for circulation will _all_ come back, _on an average_, once in three months, and be redeemed by the bankers, by being accepted in payment of the notes discounted.
Then the bank notes will be re-issued, by discounting new notes, and will go into circulation again; to be again brought back, at the end of another three months, and redeemed, by being accepted in payment of the new notes discounted.
In this way the bank notes will be continually re-issued, and redeemed, in the greatest amounts that can be kept in circulation long enough to earn such an amount of interest as will make it an object for the bankers to issue them.
Each of these notes, issued for circulation, if known to be solvent, will always have the same value in the market, as the same nominal amount of coin. And this value is a just one, because the notes are in the nature of a lien, or mortgage, upon so much property of the bankers as is necessary to pay the notes, and as can be taken by law, and sold, and the proceeds applied to their payment.
There is no danger that any more of these notes will be issued than will be wanted for buying and selling property at its true and natural market value, relatively to coin; for as the notes are all made legally payable in coin on demand, if they should ever fall below the value of coin in the market, the holders of them will at once return them to the banks, and demand coin for them; _and thus take them out of circulation_.
The bankers, therefore, have no motive for issuing more of them than will remain long enough in circulation, to earn so much interest as will make it an object to issue them; the only motive for issuing them being to draw interest on them while they are in circulation.
The bankers readily find how many are wanted for circulation, by the time those issued remain in circulation, before coming back for redemption. If they come back immediately, or very quickly, after being issued, the bankers know that they have over-issued, and that they must therefore pay in coin--to their inconvenience and perhaps loss--notes that would otherwise have remained in circulation long enough to earn so much interest as would have paid for issuing them; and would then have come back to them in payment of notes discounted, instead of coming back on a demand for redemption in coin.
