I answer, that if the banks, in such a case, do not follow the plan I have proposed, the consequence will be, that two hundred thousand pounds of their paper will be, the first year, taken out of the domestic circulation of Scotland; will be carried to the bank, and coin demanded for it. If the coin is found in the bank, it is well; it goes away, and leaves the paper circulation of Scotland at 800,000_l_. This void must occasion applications to the bank for credits to supply it. Is it not then the interest of the bank to supply it? We have said in the former chapters that it is. But now let us suppose it objected, that if banks should issue notes at such a time, their cash having been exhausted, they would be obliged to stop altogether, upon a return of those notes issued upon additional credits. To this I repeat again, because of the importance of the subject, that notes issued to support the demand of circulation never can return upon the bank, so as to form a demand for coin; and if they do return, it must be in order to extinguish the securities granted by those who have credit in bank (I except always that regular demand for coin, at all times necessary for circulating the paper for domestic uses) and if those notes return of themselves, without being called in, this phænomenon would be a proof that circulation is diminishing of itself: but supposing such a case to happen, it is plain that such return can produce no call for coin; because when the notes return it is not for coin, but for acquitting an obligation or mortgage, as has been often repeated. Notes are paid in, I say, because circulation has thrown them out. Now if circulation has thrown them out as superfluous, it never can have occasion for coin in their stead; because coin answers the same purpose. But then it is urged that they do not return, because circulation has thrown them out, but because coin is wanted: be it so. Then we must say, that circulation is not diminished, as we at first supposed; but that the return of another year’s balance, makes a new demand for coin necessary.
