 rates of compensation for risk added to this will give the current rates of commercial interest.

Now, it is evident that the greatest differences in what is ordinarily called interest are due to differences in risk; but it is also evident that between different countries and different times there are also considerable variations in the rate of interest proper. In California at one time two per cent. a month would not have been considered extravagant interest on security on which loans could now be effected at seven or eight per cent. per annum, and though some part of the difference may be due to an increased sense of general stability, the greater part is evidently due to some other general cause. In the United States generally the rate of interest has been higher than in England; and in the newer States of the Union higher than in the older States; and the tendency of interest to sink as society progresses is well marked and has long been noticed. What is the law which will bind all these variations together and exhibit their cause?

It is not worth while to dwell more than has hitherto incidentally been done upon the failure of the current political economy to determine the true law of interest. Its speculations upon this subject have not the definiteness and coherency which have enabled the accepted doctrine of wages to withstand the evidence of fact, and do not require the same elaborate review. That they run counter to the facts is evident. That interest does not depend on the productiveness of labor and capital is proved by the general fact that where labor and capital are most productive interest is lowest. That it does not depend reversely upon wages (or the cost of labor), lowering as wages rise, and increasing as wages fall, is proved by the general fact that interest is high when and where wages are high, and low when and where wages are low.

Let us begin at the beginning. The nature and functions of capital have already been sufficiently shown, but
