such as to equalize the demand for loans with the supply of them. It will be such, that exactly as much as some people are desirous to borrow at that rate, others shall be willing to lend. If there is more offered than demanded, interest will fall; if more is demanded than offered, it will rise; and in both cases, to the point at which the equation of supply and demand is re-established.

Both the demand and supply of loans fluctuate more incessantly than any other demand or supply whatsoever. The fluctuations in other things depend on a limited number of influencing circumstances; but the desire to borrow, and the willingness to lend, are more or less influenced by every circumstance which affects the state or prospects of industry or commerce, either generally or in any of their branches. The rate of interest, therefore, on good security, which alone we have here to consider (for interest in which considerations of risk bear a part may swell to any amount) is seldom, in the great centres of money transactions, precisely the same for two days together; as is shown by the never-ceasing variations in the quoted prices of the funds and other negotiable securities. Nevertheless, there must be, as in other cases of value, some rate which (in the language of Adam Smith and Ricardo) may be called the natural rate; some rate about which the market rate oscillates, and to which it always tends to return. This rate partly depends on the amount of accumulation going on in the hands of persons who cannot themselves attend to the employment of their savings, and partly on the comparative taste existing in the community for the active pursuits of industry, or for the leisure, ease, and independence of an annuitant.


§ 2.To exclude casual fluctuations, we will suppose commerce to be in a quiescent condition, no employment being unusually prosperous, and none particularly distressed. In these circumstances, the more thriving producers and traders have their capital fully employed, and many are able
