In each week, the invested variable capital of 100 p. st. produces a surplus-value of 100 p. st., hence in 50 weeks the total invested capital produces a surplus-value of 50 times 100, or 5000 p. st. The quantity of the surplus-value produced per year is the same as in the previous case, 5000 p. st., but the annual rate of surplus-value is entirely different. It is equal to the surplus-value produced in one year, divided by the advanced variable capital, that is to say it is as 5000 s to 5000 v, or 100%, while in the case of capital In the case of both capitals A and B, we have invested a variable capital of 100 p. st. per week. The rate of surplus-value per week, or the intensity of self-expansion, is likewise the same, 100%, so is the magnitude of the variable capital the same, 100 p. st. The same quantity of laborpower is exploited, the volume and intensity of exploitation are equal in both cases, the working days are the same and subdivided in the same way in necessary labor and surpluslabor. The quantity of variable capital employed in the course of the year is 5000 p. st. in either case, sets the same amount of labor in motion, and extracts the same amount of surplus-value from the labor power set in motion by these two equal capitals, namely 5000 p. st. Nevertheless, there is a difference of 900% in the annual rate of surplus-value of the two capitals A and B.
This phenomenon makes indeed the impression as though the rate of surplus-value were not only dependent on the quantity and intensity of exploitation of the labor-power set in motion by the variable capital, but also on inexplicable influences arising from the process of circulation. It has actually been so interpreted, and has completely routed the Eicardian school since the beginning of the twenties of the 19th century, at least in its more complicated and disguised form, that of the annual rate of profit, if not in the simple and natural form indicated above.
The strangeness of this phenomenon disappears at once, The Turn-Over of the Variable Capital. 341 when we piace capital A and B in exactly the same conditions, not peemingly, but actually. These equal circumstances are present only when the variable capital B is expended in the payment of labor-power in its entire volume and in the same period of time as capital A.
In that case, the 5000 p. st. of capital B are invested for 5 weeks. 1000 p. st. per week makes an investment of 50,000 p. st. per year. The surp^s-value is then likewise 50,000 p. st., according to our assumption. The turned-over capital of 50,000 p. st., divided by the advanced capital of 5000 p. st., makes the number of turn-overs 10. The rate of surplusvalue, 5000 to 5000, or 100%, multiplied by the number of turn-overs, 10, makes the annual rate of surplus-value as 50,000 to 5000, or 10 to 1, or 1000%. Now the annual rates of surplus-value for A and B are alike, namely 1000%, but the quantities of surplus-value are 50,000 p. st. in the case of B, and 5000 p. st. in the case of A. The quantities of the produced surplus-values now are proportioned to one another as the advanced capital-values of B and A, to-wit: as 50,000 to 5000, or 10 to 1. But at the same time, capital B has set in motion ten times as much labor-power as capital A has in the same time.
It is only the capital actually invested in the working process which produces any surplus-value and for which all laws relating to surplus-value are in force including for instance the law according to which the quantity of surplus-value is determined by the relative magnitude of the variable capital if the rate of surplus-value is given.
The labor-process itself is determined by the time. If the length of the working period is given (as it is here, where we assume all circumstances relating to A and B to be equal, in order to elucidate the difference in the annual rate of surplus-value), the working week consists of a certain number of working days. Or, we may consider any working period, for instance this working period of 5 weeks, as one single working day of 300 hours, if the working day has 10 hours and the working week 6 days. We must further multiply this number with the number of laborers who are employed every day simultaneously in the same labor- 342 Capital.
process. If there were 10 laborers, there would be 60 times 10, or 600 working hours in one week, and a working period of 5 weeks would have 600 times 5, or 3000 working hours. Variable capitals of equal magnitude are, therefore, employed, the rate of surplus-value and the working days being the same if equal quantities of labor-power are set in motion in the same time (a labor-power of the same price multiplied with the same number).
Let us now return to our original illustrations. In both cases, A and B, equal variable capitals, of 100 p. st. per week, are invested every week during the year. The invested variable capitals actually serving in the labor-process are, therefore, equal, but the advanced variable capitals are very unequal. For A, 500 p. st. are advanced for every 5 weeks, and 100 p. st. of this are consumed every week. In the case of B, 5000 p. st. must be advanced for first period of 5 weeks, but only 100 p. st. per week, or 500 in 5 weeks, or one-tenth of the advanced capital is employed. In the second period of 5 weeks, 4500 p. st. must be advanced, but only 500 of this is employed, etc. The variable capital advanced for a certain period of time is converted into employed, actually serving and active, variable capital only to the extent that it actually steps into the period of time taken up by the labor-process, to the extent that it actually takes part in it-In the intermediate time in which a certain portion of this capital is advanced, with a view to being employed at a later time, this portion is practically non-existing for the labor-process and has, therefore, no influence on the formation of either value or surplus-value. Take, for instance, capital A, of 500 p. st. It is advanced for 5 weeks, but only 100 p. st. enter successively week after week into the labor process. In the first week, one-fifth of this capital is employed; four-fifths are advanced without being employed, although they must be available, and therefore advanced, for the labor-processes of the following 4 weeks.
The circumstances which differentiate the relations of the advanced to the employed capital, influence the production of surplus-value — the rate of surplus-value being given — only to the extent that they differentiate the quantity of The Turn-Over cf the Variable Capital. 343 variable capital which can be actually employed in a certain period of time, for instance in one week, 5 weeks, etc. The advanced variable capital serves as variable capital only for the time that it is actually employed, not for the time in which it is held available without being employed. But all the circumstances which differentiate the relations between the advanced and the employed variable capital, are comprised in the difference of the periods of turn-over (determined by the difference in the working period, the circulation period or both). The law of the production of surplus-value decrees that equal quantities of employed variable capital produce equal quantities of surplus-value, if the rate of surplus-value is the same. If, then, equal quan< tities of variable capitals are employed by the capitals A and B in equal periods of time with an equal rate of surplusvalue, they must produce equal quantities of surplus-value in equal periods of time, no matter what may be the proportion of this variable capital, employed during definite periods of time to the variable capital advanced for the same time and no matter, therefore, what may be the proportion of the quantities of surplus-value produced, not to the employed, but to the total advanced variable capital in general. The difference of this proportion, so far from contradicting the laws of the production of surplus-value demonstrated by us, rather corroborates them and is one of their inevitable consequences.
Let us consider the first productive section of 5 weeks of capital B. At the end of the fifth week, 500 p. st. have been employed and consumed. The value of the product is 100 p. st., hence the rate as 500 s to 500 v or 1100%, the same as in the case of capital A. The fact that, in the case of capital A, the surplus-value is realized together with the advanced capital, while in the case of B it is not, does not concern us here, where it is merely a question of the production of surplus-value and of its proportion to the variable capital advanced during its production. But if we calculate the proportion of surplus-value in B, not as compared to that portion of the advanced capital of 5000 p. st. which has been employed and consumed in its produc- 344 Capital.
tion, but to this total advanced capital itself, we find that it is as 500 s to 5000 v, or as 1 to 10, or 10%. In other words, it is 10% for capital B and 100% for capital A, ten times more. If any one were to say that this difference in the rate of surplus-value for equal capitals, setting in motion equal quantities of labor which is equally divided into paid and unpaid labor, is contrary to the laws of the production of surplus-value, then the answer would be simple and prompted by the mere inspection of the actual conditions: In the case of A, the actual rate of surplus-value is expressed, that is to say, the proportion of a surplus-value of 500 p. st., to a variable capital of 500 p. st., which produced it in 5 weeks. In the case of B, on the other hand, we are dealing with a calculation which has nothing to do either with the production of surplus-value, or with the determination of its corresponding rate of surplus-value. For the 500 p. st. of surplus-value produced by a variable capital of 500 p.
st. are not calculated with reference to the 500 p. rt. of variable capital advanced in their production, but with reference to a capital of 5000 p. st., nine-tenths of which, -or 4500 p. st., have nothing whatever to do with the production of this surplus-value of 500 p. st., but are rather intended for gradual service in the following 45 weeks, so that they do not exist at all so far as the production of the first 5 weeks is concerned, which is alone significant in this instance. Under these circumstances, the difference in the rate of surplusvalue of A and B is no problem at all.
Let us now compare the annual rates of surplus-value for capitals A and B. For B it is as 5000 s to 5000 v, or 100%; for A it is as 5000 s to 500 v, or 1000%. But the proportion of the rates of surplus-value toward one another is the same as before. There we had Rate of Surplus- Value of Capital B 10% Rate of Surplus- Value of Capital A 100% Now we have Annual Rate of Surplus- Value of Capital B 100% Annual Rate of Surplus- Value of Capital A 1000% The Turn-Over of the Variable Capital. 345 But 10% is to 100% as 100% is to 1000%, so that the ratio is the same.
But now the problem is reversed. The annual rate of capital B is as 5000 s to 5000 v, or 100%, offering not the slightest deviation, nor even the semblance of a deviation, from the laws of production known to us and the rate of surplus-value corresponding to this production. 5000 v have been advanced and consumed productively during the year, and they have produced 5000 s. The rate of surplus-value is, therefore the same as shown in the above proportion, 5000 s to 5000 v, or 100%. The annual rate agrees with the actual rate of surplus-value. In this case, it is not capital B, but capital A, which presents an anomaly that is to be explained.
In the case of A, we have the rate of surplus-value as 5000 s to 500 v, or 1000%. But while in the case of B, a surplus-value of 500 p. si, the product of 5 weeks, was calculated with reference to an advanced capital of 5000 p. st., nine-tenths of which were not employed in its production, we have now a surplus-value of 5000 s calculated on a variable capital of 500 v, that is to say, on only one-tenth of the variable capital of 5000 p. st. actually employed in the production of 5000 s. For the 5000 s are the product of a variable capital of 5000 v, productively consumed during 50 weeks, not that of a capital of 500 p. st. productively consumed in one working period of 5 weeks. In the former case, the surplus-value produced in 5 weeks had been calculated for a capital advanced for 50 weeks, a capital ten times larger than the one consumed during the 5 weeks. In the present case, the surplus-value produced in 50 weeks is calculated for a capital advanced for only 5 weeks, a capital ten times smaller than the one consumed in 50 weeks.
Capital A, of 500 p. st., is never advanced for more than 5 weeks. At the end of this time it has flown back and may repeat the same process in the course of the year ten times, by ten turn-overs. Two conclusions follow from this: First. The Capital advanced in the case of A is only five times larger than that portion of capital which is con- 346 Capital.
tinually employed in the productive process of one week. Capital B, on the other hand, which is turned over only once in 50 weeks, is fifty times larger than that one of its portions which can be used only in continuous successions of one week. The turn-over, therefore, modifies the relations of the capital advanced during the year for the process of production to the capital employed continuously for a certain period of production, say, for one week. And this is illustrated by the first case, in which the surplus-value of 5 weeks is not calculated for the capital employed during these 5 weeks, but for a capital ten times larger and employed for 50 weeks.
Second. The period of turn-over of 5 weeks of capital A comprises only one-tenth of the year, so that one year contains ten such periods of turn-over, in which capital A of 500 p. st. is successively reinvested. The employed capital is here equal to the capital advanced for 5 weeks, multiplied by the number of periods of turn-over per year. The capital employed during the year is 500 times 10, or 5000 p. st. The capital advanced during the year is 5000 divided by 10, or 500 p. st. Indeed, although the 500 p. st. are always reemployed, the sum advanced for 5 weeks never exceeds these same 500 p. st. On the other hand, in the case of capital B, it is true that only 500 p. st. are employed for 5 weeks and advanced for these 5 weeks. But as the period of turn-over is in this case 50 weeks, the capital employed in one year is equal to the capital advanced for 50 weeks, not to that advanced for every 5 weeks. But the annual quantity of surplus-value depends, given the rate of surplusvalue, on the capital employed during the year, not on the capital advanced for the year. Hence it is not larger for this capital of 5000 p. st., which is turned over once a year, than it is for the capital of 500 p. st., which is turned over ten times per year. And it has this size only because the capital turned over once a year is ten times larger than the capital turned over ten times per year.
The variable capital turned over during one year — and hence that portion of the annual product, or of the annual expenditure, which is equal to that portion — is the variable The Turn-Over of the Variable Capital. 347 capital employed and productively consumed during the year. It follows that, assuming the variable capital A turned over annually and the variable capital B turned over annually to be equal, and to be employed under equal conditions of investment, so that the rate of surplus-value is the same for both of them, the quantity of surplus-value produced annually must likewise be the same for both of them. Hence the annual rate of surplus-value must also be the same for them so far as it is expressed by the formula Quantity of Surplus- Value Produced Annually Variable Capital Turned-Over Annually.
Or, generally speaking: Whatever may be the relative magnitude of the turned over variable capitals, the rate of the surplus-value produced by them in the course of the year is determined by the rate of surplus-value at which the respective capitals have been employed in average periods (for instance the average of a week or a day).
This is the only result following from the laws of the production of surplus-value and the determination of the rate of surplus- value.
Let us now consider what is expressed by the ratio of the Capital Turned-Over Annually Capital Advanced taking into account, as we have said before, only the variable capital. The division shows the number of turn-overs made by the capital advanced in one year. In the case of capital A, we have: 5000 p. st. of Capital Turned-Over Annually 500 p. st. of Capital Advanced In the case of capital B, we have: 5000 p. st. of Capital Turned Over Annually 5000 p. st. of Capital Advanced 348 Capital.
In both ratios, the numerator expresses the capital advanced multiplied by the number of turn-overs, in the case of A, 500 times 10, in the case of B 5000 times 1. Or, it may be multiplied by the inverted time of turn-over calculated for one year. The time of turn-over for A is 1-10 year; the inverted time of turn-over is 10-1 year, hence we have 500 times 10-1, or 5000. In the case of B, 5000 times 1-1. The denominator expresses the turned over capital multiplied by the inverted number of turn-overs; in the case of A, 5000 times 1-10, in the case of B, 5000 times The respective quantities of labor (the sum of the paid and unpaid labor), which is set in motion by the two variable capitals turned over annually, are equal in this case, because the turned-over capitals themselves are equal and their rate of self-expansion is likewise equal.
The ratio of the variable capital turned over annually to the variable capital advanced indicates (1) the ratio of the capital intended for investment to the variable capital employed during a definite working period. If the number of turn-overs is 10, as in the case of A, and the year is assumed to have 50 working weeks, then the period of turnover is 5 weeks. For these 5 weeks, variable capital must be advanced, and the capital advanced for 5 weeks must be 5 times as large as the variable capital employed during one week. That is to say, only one-fifth of the advanced capital (in this case of 500 p. st.) can be employed in the course of one week. On the other hand, in the case of capital B, where the number of turn-overs is 1-1, the time of turn-over is 1 year of 50 weeks. The ratio of the advanced capital to the capital employed weekly is, therefore, as 50 to 1. If matters were the same for B as they are for A, then B would have to invest 1000 p. st. per week instead of 100. (2). It follows, that B has employed ten times as much capital (5000 p. st.) as A, in order to set in motion the same quantity of variable capital and, the rate of surplus-value being the same, of labor (paid and unpaid), and thus to produce the same quantity of surplus-value during one year. The current rate of surplus-value ex- The Turn-Over of the Variable Capital. 349 presses nothing but the ratio of the variable capital employed during a certain period to the surplus-value produced in the same time; or, the quantity of unpaid labor set in motion by the variable capital employed during this time. It has absolutely nothing to do with that portion of the variable capital which is advanced for a time in which it is not employed. Hence it has nothing to do, in the case of different capitals, with the ratio, determined and differentiated by the period of turn-over, of that portion of capital which is advanced for a definite time and that portion which is employed in the same time.
The essential result of the preceding analysis is that the annual rate of surplus-value coincides only in one single case with the current rate of surplus-value which expresses the intensity of exploitation, namely in the case that the advanced capital is turned over only once a year, so that the capital advanced is equal to the capital turned over in the course of the year, so that the ratio of the quantity of surplus-value produced during the year to the capital employed during the year in this production coincides with and is identical with the ratio of the quantity of surplus-value produced during the year to the capital advanced during the year.
(A) The annual rate of surplus-value is equal to the Quantity of Surplus- Value Produced during the Year Variable Capital Advanced But the quantity of the surplus-value produced during the year is equal to the current rate of surplus-vaiue multiplied by the variable capital employed in its production. The capital employed in the production of the annual quantity of surplus-value is equal to the advanced capital multiplied by the number of its turn-overs, which we shall call n in the present case. Substituting these terms in formula (A) we obtain: (B) The annual rate of surplus-value is equal to the 350 Capital.

For instance, in the case of capital B, we should have Only when n is equal to 1, that is to say when the variable capital advanced is turned over once a year, so that it is equal to the capital employed or turned over, the annual rate of surplus-value is equal to the current rate of surplusvalue.
Let us call the annual rate of surplus-value S\ the current rate of surplus-value s', the advanced variable capital v, the number of turn-overs n. Then s'vn S' is equal to, or s'n.
v In other words, S' is equal to s'n, and it is equal to s' only when n is 1, so that then S' is s' times 1, or s'.
It follows furthermore that the annual rate of surplusvalue is always equal to s'n, that is to say, always equal to the current rate of surplus-value produced in one period of turn-over by the variable capital consumed during that period multiplied by the number of turn-overs of this variable capital during one year, or, what amounts to the same, multiplied with its inverted time of turn-over calculated for one year. (If the variable capital is turned over ten times per year, then its time of turn-over is 1-10 year, its inverted time of turn-over therefore 10-1 year, or 10 years.)
"We have seen that S' is equal to s', when n is 1. S' is greater than s', when n is greater than 1, that is to say, when the advanced capital is turned over more than once a year, or the turned over capital is greater than the capital advanced.
Finally, S' is smaller than s', when n is smaller than 1, that is to say, when the capital turned over during one The Turn-Over of the Variable Capital. 351 year is only a part of the advanced capital, so that the period of turn-over is longer than* one year.
Let us linger a moment over this last case.
We retain all the premises of our former illustration, only the period of turn-over is to be 55 weeks instead of 50 weeks. The labor-process requires a variable capital of 100 p. st. per week, so that 5500 p. st. are needed for the period of turn-over, and every week 100 s is produced, s' is, therefore, smaller than 100%. Indeed, if the annual rate turn-overs, n, is then_ or, because the time of turnover is 1 plus 1-10 year (of 50 weeks), or 11-10 year. S' is equal to equal to 100 times 10-11, or 1000-11, or 90 10-11%. It is, therefore, smaller than 100%. Indeed, if the annual rate of surplus-value were 100%, then 5500 v would have to produce 5500 s, while 11-10 years are required for that. The 5500 v produce only 5000 s during one year, therefore the annual rate of surplus- value is s, or 10-11, or 90 The annual rate of surplus-value, or the comparison between the surplus-value produced during one year and the variable capital advanced (as distinguished from the variable capital turned over during one year), is therefore not merely a subjective matter, but the actual movement of capital causes this juxtaposition. So far as the owner of capital A is concerned, his advanced variable capital of 500 has returned to him at the end of the year, and it has produced 5000 p. st. of surplus-value in addition. It is not the quantity of capital employed by him during the year, but the quantity returning to him periodically, that expresses the magnitude of his advanced capital. It is immaterial for the present question, whether the capital exists at the end of the year partly in the form of a productive supply, or partly in that of money or commodity-capital, and what may be the proportions of these different parts. On the 352 Capital.
other hand, so far as the owner of capital B is concerned, his advanced capital of 5000 p. st. has returned to him. with an additional surplus-value of 5000 p. st. And as foi the owner of capital C (the last mentioned 5500 p. st.), surplus-value to the amount of 5000 p. st. has been produced for him (advanced 5000 p. st., rate of surplus-value 100%), but his advanced capital has not yet returned to him nor has he pocketed his surplus-value.
The formula S' equal to s'n indicates that the rate of surplus-value in force for the employed variable capital, to wit, Quantity of S.-V. produced in one Period of T.-O.
Var. Cap, employed in one Period of T.-O.
must be multiplied with the number of periods of turn-over, or of the periods of reproduction of the advanced variable capital, that number of periods in which it renews its cycle.
We have seen already in volume I, chapter IV (The Transformation of Money into Capital), and furthermore in volume I, chapter XXIII (Simple Reproduction), that the capital value is not all spent, but advanced, as this value, having passed through the various phases of its cycle, returns to its point of departure, enriched by surplus-value. This fact shows that it has been merely advanced. The time consumed from the moment of its departure to the moment of its return is the one for which it was advanced. The entire rotation of capital-value, measured by the time from its advance to its return, constitutes its turn-over, and the duration of this turn-over is a period of turn-over. When this period has elapsed and the cycle is completed, the same capital-value can renew the same rotation, can expand itself some more, create some more surplus-value. If the variable capital is turned over ten times in one year, as in the case of capital A, then the same advance of capital creates in the course of one year, ten times the quantity of surplus-value created in one period of turn-over.
One must come to a clear conception of the nature of this advance from the standpoint of capitalist society.
Capital A, which is turned over ten times in one year, is The Turn-Over of the Variable Capital. 353 advanced ten times during one year. It is advanced anew for every new period of turn-over. But at the same time, A never advances more than this same capital-value of 500 p. st., and disposes never of more than these 500 p. st. for the productive process considered by us. As soon as these 500 p. st. have completed one cycle, A starts them once more on the same cycle. In short, capital by its very nature preserves its character as capital only by means of continued service in successive processes of production. In the present case, it was never advanced for more than 5 weeks. If the turn-over lasts longer, this capital is inadequate. If the turn-over is contracted, a portion of this capital is released. Not ten capitals of 500 p. st. are advanced, but one capital of 500 p. st. is advanced ten times in successive intervals. The annual rate of surplus-value is, therefore, not calculated on ten advances of a capital of 500 p. st., not on 5000 p. st., but on one advance of a capital of 500 p. st. It is the same in the case of one dollar which circulates ten times and yet represents never more than one single dollar in circulation, although it performs the function of 10 dollars. But in the hand, which holds it after each change of hands, it remains the same value of one dollar as before.
Just so the capital A indicates at each successive return, and likewise at its return at the end of the year that its owner has operated always with the same capital-value of 500 p. st. Hence only 500 p. st. flow back into his hand at each turn-over. His advanced capital is never more than 500 p. st. Hence the advanced capital represents the denominator of the fraction which expresses the annual rate of surplus-value. We had for it the formula s'vn S' equal to, or s'n.
v As the current rate of surplus-value, a', is equal to ', equal to the quantity of surplus-value divided by the variable capital which produced it, we may substitute the value of s' in s'n, that is to say %, in our formula, thus making it S' equal to 8°. But by its tenfold turn-over, and thus the tenfold re- 354 Capital.
newal of its advance, the capital of 500 p. st. performs the function of a ten times larger capital, of a capital of 5000 p. st., just as 500 dollar coins, which circulate ten times per year, perform the same function as 1000 dollar coins which circulate once a year.
II. The Turn-Over of the Individual Variable Capital.
"Whatever the form of the process of production in a society, it must be a continuous process, must continue to go periodically through the same phases...When viewed, therefore, as a connected whole, and as flowing on with incessant renewal, every social process of production is, at the same time, a process of reproduction...As a periodic increment of the capital advanced, or periodic fruit of capital in process, surplus-value acquires the form of a revenue flowing out of capital." (Volume I, chapter XXIII, pages In the case of capital A, we have 10 periods of turn-over of 5 weeks each. In the first period of turn-over, 500 p. st. of variable capital are advanced, that is to say, 100 p. st. are converted into labor-power every week, so that 500 p. st., have been converted into labor power at the end of the first period of turn-over. These 500 p. st., originally a part of the total capital advanced, have then ceased to be capital. They are paid out in wages. The laborers in their turn pay them out in the purchase of means of subsistence, consuming subsistence to the amount of 500 p. st. A quantity of commodities of that value is therefore annihilated (what the laborer may save up in money, etc., is not capital). This quantity of commodities has been consumed unproductively from the standpoint of the laborer, except in so far as it preserves his labor-power, an indispensable instrument of the capitalist. In the second place, these 500 p. st. have been converted, from the standpoint of the capitalist, into labor-power of the same value (or price). Laborpower is consumed by him productively in the labor-process. At the end of 5 weeks, a product valued at 1,000 p. st. has been created. Half of this, or 500 p. st., is the reproduced value of the variable capital paid out for wages. The other The Turn-Over of the Variable Capital. 855 half, or 500 p. st., is newly produced surplus-value. But 5 weeks of labor-power, by the consumption of which a portion of a capital was transformed into variable capital, is likewise expended, consumed, although productively. The labor which was active yesterday is not the one which is active today. Its value, together with that of the surplusvalue created by it, exists now as the value of a thing separate from labor-power, to wit, a product. But by converting the product into money, that portion of it, which is equal to the value of the variable capital advanced, may once more be transformed into labor-power and thus perform again the functions of variable capital. It is immaterial that the same laborers, that is to say, the same bearers of the labor-power may be employed not only with the reproduced, but also with the reconverted capital-value in the form of money. It might be possible that the capitalist might hire different laborers for the second period of turn-over.
