570 five years he can sell it for as much more than the cloth, as amounts to five years' profit, accumulated at compound interest. The wine and the cloth were made by the same original outlay. Here then is a case in which the natural values, relatively to one another, of two commodities, do not conform to their cost of production alone, but to their cost of production plus something else. Unless, indeed, for the sake of generality in the expression, we include the profit which the wine-merchant foregoes during the five years, in the cost of production of the wine: looking upon it as a kind of additional outlay, over and above his other advances, for which outlay he must be indemnified at last.

All commodities made by machinery are assimilated, at least approximately, to the wine in the preceding example. In comparison with things made wholly by immediate labour, profits enter more largely into their cost of production. Suppose two commodities, A and B, each requiring a year for its production, by means of a capital which we will on this occasion denote by money, and suppose to be 1000l. A is made wholly by immediate labour, the whole 1000l. being expended directly in wages. B is made by means of labour which costs 500l. and a machine which cost 500l., and the machine is worn out by one year's use. The two commodities will be exactly of the same value; which, if computed in money, and if profits are 20 per cent per annum, will be 1200l. But of this 1200l., in the case of A, only 200l., or one-sixth, is profit: while in the case of B there is not only the 200l., but as much of 500l. (the price of the machine) as consisted of the profits of the machine-maker; which, if we suppose the machine also to have taken a year for its production, is again one-sixth. So that in the case of A only one-sixth of the entire return is profit, whilst in B the element of profit comprises not only a sixth of the whole, but an additional sixth of a large part.

The greater the proportion of the whole capital which consists of machinery, or buildings, or material, or anything
