The quantity of stock, therefore, or, as it is commonly expressed, of money, which can be lent at interest in any country, is not regulated by the value of the money, whether paper or coin, which serves as the instrument of the different loans made in that country, but by the value of that part of the annual produce, which, as soon as it comes either from the ground, or from the hands of the productive labourers, is destined, not only for replacing a capital, but such a capital as the owner does not care to be at the trouble of employing himself.
