The Process of Circulation of Capital (Capital Vol. II). Karl Marx

of the value of his own supply to the market.

      It still remains to anticipate the analysis of the problem of turn-over. Let the total capital of the capitalist be 5,000 pounds sterling, of which 4,000 pounds is fixed and 1,000 pounds circulating capital; these 1,000 pounds sterling are composed of 800 c plus 200 v, as assumed before. His circulating capital must be turned over five times per year in order that his fixed capital may be turned over once. His commodity-product is then equal in value to 6,000 pounds sterling, it is valued at 1,000 pounds sterling more than his advanced capital, so that the same proportion of surplus-value is obtained as before:

      5,000 C÷1,000 s=100(c+v)÷20 s.

      This turn-over does not change anything in the proportion of the total demand of the capitalist to his total supply. The former remains one-fifth smaller than the latter.

      Take it that his fixed capital must be reproduced in 10 years. Hence he sinks every year one tenth, or 400 pounds sterling, so that he has only a value of 3,600 pounds of fixed capital left plus 400 pounds in money. Inasmuch as repairs are necessary which do not exceed the average, they represent nothing but capital invested later. We may look at the matter from the standpoint that he has allowed for the expenses for repairs when calculating the value of his investment, so far as this enters into the annual commodity-product, so that they are included in that one tenth of sinking fund. If the repairs cost less than the average he is so much money in pocket, and in the reverse case he loses it. At any rate, although his demand, after his total capital has been turned over once a year, still remains at 5,000 pounds sterling which was the value of the original capital advanced, it increases so far as the circulating part of this capital is concerned, while it decreases so far as the fixed part is concerned.

      We now come to the question of reproduction. Take it that the capitalist consumes the entire surplus-value composed of money m and reconverts only the original capital-value C into productive capital. Then the demand of the capitalist is equal to his supply; but this does not refer to the movements of his capital. As a capitalist, his demand is only for four-fifths of value of his supply. He consumes one-fifth as a non-capitalist; he consumes it, not in the performance of his function as capitalist, but for his private requirements or pleasure.

      His calculation, expressed in percentages, stands as follows:

Demand as capitalist...	100, supply	120.
Demand as man of the world	20, supply	0.
Total demand...	120, supply	120.

      This assumption amounts to a non-existence of capitalist production, and thus the non-existence of the industrial capitalist himself. For capitalism is destroyed in its very foundation, if we assume that its compelling motive is enjoyment instead of the accumulation of wealth.

      But such an assumption is also technically impossible. The capitalist must not only form a reserve-capital as a protection against fluctuations of value and as a fund enabling him to wait for favorable conditions of the market for sale and purchase; he must also accumulate capital, in order to extend his production and embody the progress of technique in his productive organization.

      In order to accumulate capital, he must first withdraw a a part of the surplus-value from circulation which he obtained from that circulation in the form of money, and must hoard it until it has increased sufficiently for the extension of his old business or the opening of a side-line. So long as the formation of the hoard continues, it does not increase the demand of the capitalist. The money is then inactive. It does not withdraw from the commodity-market any equivalent in commodities for the money-equivalent which it withdrew for commodities supplied to it.

      Credit is not considered here. And credit includes the depositing, on the part of the capitalist, of accumulating money in a bank on payment of interest as shown by a running account.

      5. The Time of Circulation*2

       Table of Contents

      We have seen that the movement of capital through the sphere of production and the two phases of circulation takes place in a succession of time. The duration of its sojourn in the sphere of production is its time of production, that of its stay in the sphere of circulation its time of circulation.

      The time of production naturally includes the period of the labor-process, but is not comprised in it. We must first remember that a part of the constant capital exists in the form of instruments of production, such as machinery, buildings, etc., which serve for the repeated labor-processes until they are worn out. Periodical interruptions of the labor-process by night, etc., interrupt the function of these instruments of production, but not their location on the place of production. They belong to this place when they are not in function as well as when they are. On the other hand, the capitalist must have a definite supply of raw material and auxiliary substances in readiness, in order that the process of production may take place for a longer or shorter time on a previously determined scale, without being dependent on the accidents of a daily supply from the market. This supply of raw material, etc., is consumed productively by degrees. There is, therefore, a difference between its time of production8 and its time of function. The time of production of the means of production in general comprises, therefore, first the time during which they serve as means of production by taking part in the productive process; second, the stops during which a certain process of production, and thus the function of the means of production embodied in it, is interrupted; third, the time during which the means of production are held in readiness as requirements for the process of production, during which they represent productive capital, without having entered into the process of production.

      The difference so far discussed is always the difference between the time which the productive capital passes in the sphere of production and that in the process of production. But the process of production itself may require interruptions of the labor-process, and thus of the labor time, and during such pauses the object of labor is exposed to the influence of physical processes without the intervention of human labor. The process of production, and thus the function of the means of production, continue in this case, although the labor-process, and thus the function of the means of production as instruments of labor, have been interrupted. This applies, for instance, to the grain, after it has been sowed, the wine fermenting in the cellar, the labor-material of many manufacturers, such as tanneries, where the material is given over to chemical processes. The time of production is then greater than the labor-time. The difference between the two consists in an excess of the time of production over the labor-time. This excess always arises by the latent existence of productive capital in the sphere of production, without performing its function in the process of production itself, or by the performance of its function in the productive process without taking part in the labor-process.

      That part of the latent productive capital, which is held in readiness as a requirement for the productive process, such as cotton, coal, etc., in a spinnery, produces neither products nor value. It is fallow capital, although its fallow condition is a requirement for the uninterrupted flow of the process of production. The buildings, apparatus, etc., necessary for the storage of the productive supply (latent capital) are requirements of the productive process and therefore component parts of the advanced productive capital. They perform their function as conservators of the elements of production in a preliminary stage. Inasmuch as labor-processes are required in this stage, they add to the cost of the raw material, etc., but they are productive labor and produce surplus-value, because a part of this labor, like all wage-labor, is not paid. The normal interruptions of the entire process of production, the pauses in which the productive capital does not perform any functions, create neither value nor surplus-value. Hence the tendency to keep the work going at night (Volume I, chapter X, 4).—The intervals in the labor-time, which the object of labor must endure in the process of production itself, create neither value nor surplus-value. But they advance the product, form a
