the owners themselves employ their own capitals. Even in the monied interest, however, the money is, as it were, but the deed of assignment, which conveys from one hand to another those capitals which the owners do not care to employ themselves. Those capitals may be greater in almost any proportion, than the amount of the money which serves as the instrument of their conveyance; the same pieces of money successively serving for many different loans, as well as for many different purchases. A, for example, lends to W a thousand pounds, with which W immediately purchases of B a thousand pounds worth of goods. B having no 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 monied 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 monied 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. Though money, either coin or paper, serves generally as the deed of assignment both to the smaller, and to the more considerable portion, it is itself altogether different from what is assigned by it.

In proportion as that share of the annual produce which, as soon as it comes either from the ground, or from the hands of the productive labourers, is destined for replacing a capital, increases in any country, what is called the monied interest naturally increases with it. The increase of those particular capitals from which the owners wish to derive a revenue, without being at the trouble of employing them themselves, naturally accompanies the general increase of capitals; or, in other words, as stock increases, the quantity of stock to be lent at interest grows gradually greater and greater.

As the quantity of stock to be lent at interest increases, the interest, or the price which must be paid for the use of that stock, necessarily diminishes, not only from those general causes which make the market price of things commonly diminish as their quantity increases, but from other causes which are peculiar to this particular case. As capitals increase in any country, the profits which can be made by employing them necessarily diminish. It becomes gradually more and more difficult to find within the country a profitable method of employing any new capital. There arises in consequence a competition between different capitals, the owner of one endeavouring to get possession of that employment which is occupied by another. But upon most occasions he can hope to justle that other out of this employment, by no other means but by dealing upon more reasonable terms. He must not only sell what he deals in somewhat cheaper, but in order to get it to sell, he must sometimes too buy it dearer. The demand for productive labour, by the increase of the funds which are destined for maintaining it, grows every day greater and greater. Labourers easily find employment, but the owners of capitals find it difficult to get labourers to employ. Their competition raises the wages of labour, and sinks the profits of stock. But when the profits which can be made by the use of a capital are in this manner diminished, as it were, at both ends, the price which can be paid for the use of it, that is, the rate of interest, must necessarily be diminished with them.

Mr. Locke, Mr. Law, and Mr. Montesquieu, as well as many other writers,732 seem to have imagined that the increase of the quantity of gold and silver, in consequence of the discovery of the Spanish West Indies, was the real cause of the lowering of the rate of interest through the greater part of Europe. Those metals, they say, having become of less value themselves, the use of any particular portion of them necessarily became of less value too, and consequently the price which could be paid for it. This notion, which at first sight seems so plausible, has been so fully exposed by Mr. Hume,733 that it is, perhaps, unnecessary to say anything more about it. The following very short and plain argument, however, may serve to explain more distinctly the fallacy which seems to have misled those gentlemen.

Before the discovery of the Spanish West Indies, ten percent seems to have been the common rate of interest through the greater part of
