_Improvement in the Forms of Capital._--The greatest of all the advantages that come from this division and subdivision of wealth-creating processes comes in the way of applying machinery. A machine is a hopeless specialist and can, as a rule, put only a single minute touch on the material submitted to it; and the introduction of machines differentiates capital in a way that is parallel to the minute subdivision of labor. If the machine is to work at all economically, it must put its touch quickly on one after another of a series of articles, as they are submitted to it in uninterrupted succession. If only one kind of machine were employed in the making of shoes--if, for instance, the sewing of the uppers to the soles were done on sewing machines, even though all the rest were done by hand--it would be natural and almost necessary to have one class of workers to prepare the uppers, another to prepare the soles, and a third to sew them together by aid of the machine. When the several stages of the process are thus given over to different classes of workers, the situation is ripe for the application of more machines, and inventors readily devise apparatus that will perform one or another minute part of the manufacturing process. In the end most branches of manufacture take such shapes that the raw material is intrusted to a series of machines and passes from one to another by a nearly continuous movement, till it emerges from the hands of these automata as complete as any manipulation can make it and ready for the merchants who will convey it to their customers. _Economy of Capital._--There is an economy of capital involved in the fact that instruments can be used thus continuously. A worker does not have to have several sets of tools, many of which would be idle the greater part of the time, as would be the case if the man performed several unlike operations; but the greatest economy comes from the energy, rapidity, and accuracy with which the new instruments act. The tools are far more efficient than they could be if human muscles furnished the power and eyes and nerves supplied the deftness and accuracy that the making of the goods requires. Automata which men set working excel hand tools with men wielding them by a greater ratio than can be calculated. CHAPTER V PRODUCTION A SYNTHESIS; DISTRIBUTION AN ANALYSIS
