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 burrower in return shall, during the continuance of the loan, annually assign to the lender a small 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
