While hoarding, in its abstract form as a means of enrichment, declines with the development of the capitalist system of production, that species of hoarding which is directly called for by the process of production, increases; or, to put it differently, a part of the treasure which is generally formed in the sphere of circulation of commodities, is absorbed as a reserve fund of means of payment. The more developed the capitalist system of production, the more these reserve funds are limited to the necessary minimum. Locke, in his work "On the Lowering of Interest"[1] furnishes interesting data with reference to the size of these reserve funds in his time. They show what a considerable part of the total money in circulation the reservoirs for means of payment absorbed in England just at the time when banking began to develop.
The law as to quantity of money in circulation, as it has been formulated in the analysis of the simple circulation of money, receives an essential modification when the circulation of the means of payment is taken into account. The rapidity of the circulation of money whether as circulating: medium or as means of
