The aggregate product of society has grown from 9,000 to 9,800, the surplus value of Department I from 1,000 to 1,100, and of Department II from 750 to 800. The object of the capitalist expansion of production, the increased production of surplus value, has been gained. At the same time, the material composition of the aggregate social product again shows a surplus of 600 as regards the means of production (6,600) over and above those which are actually needed (4,400 + 1,600), and also a deficit in consumer goods as against the sum total made up by the wages previously paid (_1,100v + 800v_) and the surplus value that has been created (_1,100s + 800s_). And thus we again have the material possibility as well as the necessity to use part of the surplus value, not for consumption by the capitalist class, but for a new expansion of production. The second enlargement of production, and increased production of surplus value, thus follows from the first as a matter of course and with mathematical precision. The accumulation of capital, once it has started, automatically leads farther and farther beyond itself. The circle has become a spiral which winds itself higher and higher as if compelled by a natural law in the guise of mathematical terms. Assuming that in the following years there is always capitalisation of half the surplus value, while the composition of the capital and the rate of exploitation remain unchanged, the reproduction of capital will result in the following progression: _2nd year:_ I. _4,840c + 1,210v + 1,210s = 7,260_ II. _1,760c + 880v + 880s = 3,520_ ------ Total: 10,780 _3rd year:_ I. _5,324c + 1,331v + 1,331s = 7,986_ II. _1,936c + 968v + 968s = 3,872_ ------ Total: 11,858 _4th year:_ I. _5,856c + 1,464v + 1,464s = 8,784_ II. _2,129c + 1,065v + 1,065s = 4,259_ ------ Total: 13,043 _5th year:_ I. _6,442c + 1,610v + 1,610s = 9,662_ II. _2,342c + 1,172v + 1,172s = 4,686_ ------ Total: 14,348
