§ III. CAUSES OF INDUSTRIAL COMBINATIONS [Sidenote: Trusts in the legal and the popular sense] 1. _Trusts are large combinations of capital with some degree of monopoly power._ The original, legal meaning of the term trust does not include the idea of monopoly. The old legal idea of a trust is the confidence imposed in a trustee. The method that was adopted by the early combinations was the trust method, that is, they made use of this legal device: the stock of the separate companies was put into the hands of a board of trustees to whom was thus given the right to control. As it has been found possible to accomplish the same end without the use of this legal method, the popular meaning of the word trust, as applied to a monopoly, no longer agrees with the legal meaning. The word trust is popularly used of any large industry, though usually there is connected with it the idea of some evil power to raise prices to the consumers. A large number of the corporations called trusts have, however, little monopoly power, and some have none at all. They are simply large establishments. [Sidenote: Economies of combination] 2. _A strong reason for combination of competing plants is found in the legitimate economies of large production._ The economies that are possible within a single factory may be still greater in a number of combined or federated industries. The cost of management, amount of stock carried, advertising, cost of selling the product, may all be smaller per unit of product. A large aggregation can control credit better and escape loss from bad debts. By regulating and equalizing the output in the different localities, it can run more nearly full time. Being acquainted with the entire situation, it can reduce the friction. A strong combination has advantages in shipment. It can have a clearing-house for orders and ship from the nearest source of supply. The least efficient factories can be first closed when demand falls off. Factories can be specialized to produce that for which each is best fitted. The magnitude of the industry and its presence in different localities strengthens its influence with the railroads. Its political as well as its economic power is increased. [Sidenote: Integration of industry] A recent phase of corporate growth is the "integration of industry," that is, the grouping under one control of a whole series of industries. One company may carry the iron ore through all the processes from the mine to the finished product. A railroad line across the continent owns its own steamers for shipping goods to Asia or Europe. Large wholesale houses own or control the output of entire factories. The possibilities in this direction have only begun to be realized. [Sidenote: Combination prevents competition]
