When two people, who are continually drawing and re-drawing upon one another, discount their bills always with the same banker, he must immediately discover what they are about, and see clearly that they are trading, not with any capital of their own, but with the capital which he advances to them. But this discovery is not altogether so easy when they discount their bills sometimes with one banker, and sometimes with another, and when the same two persons do not constantly draw and re-draw upon one another, but occasionally run the round of a great circle of projectors, who find it for their interest to assist one another in this method of raising money, and to render it, upon that account, as difficult as possible to distinguish between a real and a fictitious bill of exchange; between a bill drawn by a real creditor upon a real debtor, and a bill for which there was properly no real creditor but the bank which discounted it; nor any real debtor but the projector who made use of the money. When a banker had even made this discovery, he might sometimes make it too late, and might find that he had already discounted the bills of those projectors to so great an extent, that, by refusing to discount any more, he would necessarily make them all bankrupts, and thus, by ruining them, might perhaps ruin himself. For his own interest and safety, therefore, he might find it necessary, in this very perilous situation, to go on for some time, endeavouring, however, to withdraw gradually, and upon that account making every day greater and greater difficulties about discounting, in order to force those projectors by degrees to have recourse, either to other bankers, or to other methods of raising money; so as that he himself might, as soon as possible, get out of the circle. The difficulties, accordingly, which the bank of England, which the principal bankers in London, and which even the more prudent Scotch banks began, after a certain time, and when all of them had already gone too
