dimensions that the total sum of prices to be realized increases more rapidly than the rapidity of the circulation of money, the hoards decrease perceptibly; but when the combined movement slackens to an unusual extent, or the movement of buying and selling steadies itself, the medium of circulation solidifies into money in large measure, and the treasure reservoirs fill up far above their average level. In countries with an exclusively metallic circulation or where production is at a low stage of development, the hoards are endlessly split up and scattered all over the land, while in countries where the capitalist system is developed they are concentrated in bank reservoirs. Hoards are not to be confounded with coin reservoirs, which form a constituent part of the total supply of money in circulation, while the interaction between hoards and currency implies the decline or rise of its total supply. Gold and silver commodities form, as we have seen, both conduits for the withdrawal of precious metals, as well as sources of their supply. In ordinary times only their former function is of importance to the economy of metallic circulation.102
