It is peculiarly desirable to understand, consequently, just how these rebates came to be granted. It was, apparently, contrary to the interest of the railroad companies to cut their rates for the benefit of any one class of customers; and it was, also, an illegal practice, which had to be carried on by secret and underhand methods. Almost all the state laws under which corporations engaged in transportation had been organized, had defined railways, like highways, as public necessities. Such corporations had usually been granted by the states the power to condemn land,—and the delegation of such a power to a private company meant, of course, that it owed certain responsibilities to the public as a common carrier, among which the responsibility of not allowing special privileges to any one customer was manifestly to be included. When the railroad managers have been asked why they cut their published rates and evaded the laws, they have always contended that they were forced to do so; and whatever may be thought of the plea, it cannot be lightly set aside. As we have seen, the trunk lines leading from Chicago to the coast were the result of the consolidation of local roads. After the consolidations had taken place, these companies began to compete fiercely for through freight, and the rebates were an incident in this competition. The trunk lines in the early years of their existence were in the position of many other American business enterprises. For the time being, they were more than competent to carry all the freight offered at competitive points. Inasmuch as there was not enough to go around, they fought mercilessly for what business there was. When a large individual shipper was prepared to guarantee them a certain amount of freight in return for special rates, they were obliged either to grant the rates or to lose the business. Of course they submitted, and defended their submission as a measure of self-preservation.
