only a small portion of the credit-power, and it will depend only on convenience whether the portion [pg 340] which they use will be taken in one form or in another. One single exertion of the credit-power in the form of (1) book-credit, is only the foundation of a single purchase; but, if (2) a bill is drawn, that same portion of credit may serve for as many purchases as the number of times the bill changes hands; while (3) every bank-note issued renders the credit of the banker a purchasing power to that amount in the hands of all the successive holders, without impairing any power they may possess of effecting purchases on their own credit. Credit, in short, has exactly the same purchasing power with money; and as money tells upon prices not simply in proportion to its amount, but to its amount multiplied by the number of times it changes hands, so also does credit; and credit transferable from hand to hand is in that proportion more potent than credit which only performs one purchase.
There is a form of credit transactions (4) by checks on bankers, and transfers in a banker's books, which is exactly parallel in every respect to bank-notes, giving equal facilities to an extension of credit, and capable of acting on prices quite as powerfully. A bank, instead of lending its notes to a merchant or dealer, might open an account with him, and credit the account with the sum it had agreed to advance, on an understanding that he should not draw out that sum in any other mode than by drawing checks against it in favor of those to whom he had occasion to make payments. These checks might possibly even pass from hand to hand like bank-notes; more commonly, however, the receiver would pay them into the hands of his own banker, and when he wanted the money would draw a fresh check against it; and hence an objector may urge that as
