occasion for the money himself, lends the identical pieces to X, with which X immediately purchases of C another thousand pounds' worth of goods. C in the same manner, and for the same reason, lends them to Y, who again purchases goods with them of D. In this manner the same pieces, either of coin or of paper, may, in the course of a few days, serve as the instrument of three different loans, and of three different purchases, each of which is, in value, equal to the whole amount of those pieces. What the three moneyed men, A, B, and C, assign to the three borrowers, W, X, Y, is the power of making those purchases. In this power consist both the value and the use of the loans. The stock lent by the three moneyed men, is equal to the value of the goods which can be purchased with it, and is three times greater than that of the money with which the purchases are made. Those loans, however, may be all perfectly well secured, the goods purchased by the different debtors being so employed, as in due time to bring back, with a profit, an equal value either of coin or of paper. And as the same pieces of money can thus serve as the instrument of different loans to three, or for the same reason, to thirty times their value, so they may likewise successively serve as the instrument of repayment.
A capital lent at interest may, in this manner, be considered as an assignment from the lender to the borrower of a certain considerable portion of the annual produce; upon condition that the borrower in return shall, during the continuance of the loan, annually assign to the lender a smaller portion, called the interest; and at the end of it, a portion equally considerable with that which had originally been assigned to him, called the repayment.
