Such contracts reduced to a comparatively low level the necessary uncertainties of business.

It enabled the managers of these corporations to count upon a certain market for their product or a certain cost for part of their raw material; and it must be remembered that the chief object of this whole work of industrial organization was to diminish the hazards of unregulated competition and to subject large business operations to effective control.

A conspicuous instance of the effect of such interests and motives may be seen in the lease of the ore lands belonging to the Great Northern Railroad to the United States Steel Corporation.

The railroad company owned the largest body of good ore in the country outside of the control of the Steel Corporation, and if these lands had been leased to many small companies, the ability of the independent steel manufacturers to compete with the big steel company would have been very much increased.

But the Great Northern Railroad Company found it simpler and more secure to do business with one large than a number of small companies; and in this way the Steel Corporation has obtained almost a monopoly of the raw material most necessary to the production of finished steel.
