Nevertheless, in the course of time it became apparent that either the law had not lodged sufficient authority in the commission or the commission did not make use of the authority which the law had given them. In spite of the commission, the railroad companies maintained pools and charged extortionate and discriminating rates, in direct violation of the law. It is true the commissioners righted many a wrong. In investigating the complaints of shippers against railroad companies they often rendered valuable services to those who had neither the means nor the inclination to prosecute their rights in the courts of law; but as they held that they could only pass upon individual charges, and did not have the power to revise the companies' tariffs, the companies were virtually in a position to become guilty of more extortions in one day than the commission could investigate in a year. Moreover, the railroad company might be ordered by the commission to return an overcharge to a certain shipper, but this did not prevent it from continuing the excessive charge. If the overcharged shipper again wanted relief it was his privilege to again apply to the commission, and to continue this tedious process until either his or the commissioners' patience became exhausted. The people soon found that the new system of control was almost as inadequate as that which it had displaced. Some attributed the weakness of the commission to its personnel, others to the law. There is no doubt that the commission might have accomplished more than it did.
