Each reservoir is like a mill-pond which automatically begins to dry up whenever its contents are employed in actuating a useless mill; and the man who has wasted his water is able to waste no more. But the moment the divisions between the reservoirs are broken down, and the separate capitals contained in them become, as would be the case under socialism, fused together like the waters of a single lake, the director of labor who so misused any portion of this fluid stock that the products of labor, as directed by him, failed to replace the wages, would not thereby be incapacitated from continuing his misdirection’s further; for the wage-capital dissipated by his incompetence could, under these conditions, always be replaced, and its loss more or less concealed, by fresh supplies which had a really different origin. It was only in consequence of conditions resembling these that the London County Council was enabled to continue for so long its service of Thames steamboats, in spite of the fact that the labor thus employed failed to reproduce, by the functions which it performed for the public, more than a fraction of capital which was necessarily consumed in its maintenance.
