It may now be asked, If capital is not required for the payment of wages or the support of labor during production, what, then, are its functions?

The previous examination has made the answer clear. Capital, as we have seen, consists of wealth used for the procurement of more wealth, as distinguished from wealth used for the direct satisfaction of desire; or, as I think it may be defined, of wealth in the course of exchange.

Capital, therefore, increases the power of labor to produce wealth: (1) By enabling labor to apply itself in more effective ways, as by digging up clams with a spade instead of the hand, or moving a vessel by shoveling coal into a furnace, instead of tugging at an oar. (2) By enabling labor to avail itself of the reproductive forces of nature, as to obtain corn by sowing it, or animals by breeding them. (3) By permitting the division of labor, and thus, on the one hand, increasing the efficiency of the human factor of wealth, by the utilization of special capabilities, the acquisition of skill, and the reduction of waste; and, on the other, calling in the powers of the natural factor at their highest, by taking advantage of the diversities of soil, climate and situation, so as to obtain each particular species of wealth Where nature is most favorable to its production.
