Rh in the rapidity of circulation, the hoards open up and return a part of their contents to the stream of circulation. The solidification of circulating money into hoards and the outpouring of hoards into circulation is a constantly oscillating movement in which the prevalence of the one or the other tendency is determined exclusively by fluctuations in the circulation of commodities. Hoards thus serve as conduits for the supply and withdrawal of money to or from circulation, so that every time only that quantity of money circulates as coin which is required by the immediate needs of circulation. If the volume of the entire circulation suddenly expands and the fluent unity of sale and purchase assumes such 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
