And so soon as a demand for coin to pay a foreign balance begins, it is then both the duty and interest of all good citizens to be as assistant as possible to banks, by contenting themselves with paper for their own occasions, and by throwing into the bank all the coin which casually falls into their hands. As to duty, I shall offer no argument to enforce it. But I say it becomes a national concern to assist the bank; because the loss incurred by the bank in procuring coin, falls ultimately on every individual, by raising exchange; consequently, prices, by raising the interest of money to be borrowed; and last of all, by constituting a perpetual interest to be paid to foreigners, out of the revenue of the solid property of the country. Upon such occasions, a good citizen ought to blush at pulling out a purse, when his own interest, and that of his country, should make him satisfied with a pocket book. ------------------------------------------------------------------------ CHAP. XIII. _Continuation of the same Subject; and of the Principles upon which Banks ought to borrow Abroad, and give credit at Home._ In every question relative to this subject, we must return to principles. This is the only sure method of avoiding error. The intelligent reader, therefore, must excuse short repetitions, and consider them as a sacrifice he is making to those of slower capacities, to whom they are useful. The principle of banking upon mortgage, is to lend and give credit to those who have property, and a desire to melt it down. This is calculated for the benefit of trade, and for an encouragement to industry. If such banks, therefore, borrow, it must be done consistently with the principles upon which their banking is founded. If the borrowing should tend to destroy those advantages which their lending had procured, then the operation is contrary to principles, and abusive. So much for recapitulation. While trade flourishes and brings in a balance, banks never have occasion to borrow; it is then they lend and give credit. This, I believe, we may take for granted. When the country where the bank is established begins to owe a balance to other nations, the bank, as we have seen in the last chapter, is obliged to pay it in coin or in bills. We have there shewn, that in such cases it is inconsistent with their principles and interest, to withhold lending and giving credit, so far as is necessary for keeping up the fund of circulation to that standard which alienation and ready money demands require. To refuse credit, and at the same time to borrow _at home_, must then, at first sight, appear to be doubly inconsistent. But in order to set this point in the clearest light I am capable, I shall reason upon a supposition analogous to the situation of the Scotch banks, and by that means avoid abstraction as much as I can.
