The attempt by Marx to find room for the production of gold within Department I (means of production) moreover leads to dubious results. The first act of circulation between this new sub-Department (called by Marx I_g_) and Department II (consumer goods) consists as usual in the workers' purchase of consumer goods from Department II with the money obtained as wages from the capitalists. This money is not yet a product of the new period of production. It has been reserved by the capitalists of Department I_g_ out of the money contained in their product of an earlier period. This, indeed, is the normal procedure. But now Marx allows the capitalists of Department II to buy gold from I_g_ with the money they have reserved, gold as a commodity material to the value of 2. This is a leap from the production of money into the industrial production of gold which is no more to do with the problem of the production of money than with the production of boot-polish. Yet out of the 5 I_g v_ that have been reserved, 3 still remain, and as the capitalist, unable to use them as constant capital, does not know what to do with them, Marx arranges for him to add them on to his own reserve of money. Marx further finds the following way out to avoid a deficit in the constant capital of II which must be exchanged completely against the means of production (I_v_ + I_s_): 'Therefore, this money must be entirely transferred from II_c_ to II_s_, no matter whether it exists in necessities of life or articles of luxury, and vice versa, a corresponding value of commodities must be transferred from II_s_ to II_c_. Result: A portion of the surplus-value is accumulated as a hoard of money.'[93] A strange result, in all conscience! We have achieved an increase in money, a surplus of the money substance, by simply confining ourselves to the annual wear and tear of the money fund. This surplus value comes into existence, for some unknown reason, at the expense of the capitalists in the consumer goods department. They practise abstinence, not because they may want to expand their production of surplus value, let us say, but in order to secure a sufficient quantity of consumer goods for the workers engaged in the production of gold.
