The operations of corner makers are confined principally to goods which are dealt in upon commercial exchanges. One evident reason for this is that the vast purchases and sales, which are necessary in the formation of a corner are impossible without the facilities afforded by an exchange. It must be said, too, that the plain truth is that our principal commercial exchanges, while they do serve certain useful purposes, are yet practically devoted chiefly to speculation. This, simmered down to its essence, means that the business of the speculators is to bet on the future prices of the articles dealt in,—a game in which the largest players are able to influence prices to accord with their bets, and hence have their "lamb" opponents at an obvious disadvantage. The evil of this sort of commercial gambling is recognized by practical men of every class; but its cure is yet to be effected.

A sort of business allied both to trade and transportation is the business of storage or warehousing, and this has recently shown some interesting cases of monopoly.

The owners of warehouses along the Brooklyn waterfront combined their business in January, 1888, and doubled their rates for storage. In the testimony of one of the members of this trust, before the New York Legislative Committee, he said: "We want to destroy competition all we can. It is a bad thing." The owners of grain elevators at Buffalo, N. Y., have long combined to exact higher prices for the transfer of grain than would have prevailed were free competition the rule. At the session of 1887 the New York Legislature took the bull by the horns and enacted a law fixing a maximum rate for elevator charges; a statute which was based on the popular demand for its enactment, but is hard to accord with the principles of a free government.

There are a number of lines of business auxiliary to trade in which competition is more or less restricted by the fact that the amount of capital controlled and the prestige of the established firms renders it a difficult and risky matter to start a new and competing firm. The insurer of property or life, if he be wise, will demand financial stability as a first requisite for the company in which he takes a policy. The companies engaged in the business of fire insurance have long been trying to agree on some uniform standard of rates and the avoidance of all competition with each other. These combinations, however, are apt to be broken, as soon as formed, by the weaker companies, whose financial condition operates to prevent them from getting their share of the business under uniform rates. Even when this rate-cutting is stopped, there is still competition to be met from the various small mutual companies, who are necessarily outside the combination.

Banks are a necessity to the carrying on of modern commerce, and they have great power over the financial affairs of the business men of the community which they serve. As a general rule, however, they are largely owned by the merchants and others who patronize them, and the instances of this power being abused are, therefore, not common. It is to be remembered, in discussing this, as in other monopolies, that the power of a monopoly depends entirely upon its degree. A bank, trust company, or real-estate guaranty company which has a great capital, an established reputation for safety and conservatism, sole control of many special facilities, and conveniences for obtaining and dispatching business, has a real monopoly, whose degree varies with the tendency people have to patronize it instead of some weaker competitor, if one exists. There is no evil effect from the monopoly upon the community, unless it takes advantage of its power to charge a sum greater than their real worth for the services it renders, or uses it to discriminate to the injury of special persons or places.

In closing our discussion of the monopolies in trade, there is an important point to be noted. In the lines of industry considered in the preceding chapter, the monopoly was easy of maintenance because it held full control of the source of production, or of some necessary channel through which commerce must pass. No gift of nature assists to maintain a monopoly in trade. It must be wholly artificial, and it relies for its strength simply on the adherence of its members to their agreement to maintain prices. Its degree of power can never be great, compared with monopolies which control the original sources of production; for if it is attempted to put up prices inordinately, competition will start up outside of the combination, or the consumer will be led to deal directly with the producer.

Because of this weakness, the temptation is great for these monopolies to strengthen themselves in ways quite indefensible on any score. The alliance of trade monopolies with trusts, in order to strengthen themselves, we have already considered. But the trust which makes such an alliance must plead guilty to the charge of discrimination as well as monopoly. It is bad enough to raise the prices of the necessaries of life, and force the whole community to pay the tax; but it is worse to add to this the crime of discrimination against certain persons in the community, at the instance of a minor monopoly.

But the trade monopoly does not confine its sins to tempting the stronger monopoly to practise discriminations. It practises discrimination itself in some very ugly forms. A combination among manufacturers of railway car-springs, which wished to ruin an independent competitor, not only agreed with the American Steel Association that the independent company should be charged $10 per ton more for steel than the members of the combine, but raised a fund to be used as follows: When the independent company made a bid on a contract for springs, one of the members of the trust was authorized to underbid at a price which would incur a loss, which was to be paid for out of the fund. In this way the competing company was to be driven out of business. It is often argued that combinations to advance prices can never exist long, because of the premium which the advanced price puts upon the entrance to the field of new competitors; but the weapons which this trust used to ruin an old and strong competitor are even more effectual against a new-comer; and the knowledge that they are to meet such a warfare is apt to deter new competitors from entering the field.

The boycott was once deemed rather a degrading weapon of warfare; but now the term has grown to be a familiar one in trade circles. Even the great railway companies do not scruple to use the boycott in fighting their battles. One might imagine that both the thing and the name filled a long felt want.
