This is in the interest of communities and the individual shipper. There must be elasticity for other reasons, in the interest of communities as of the railroads; in meeting changes in commercial conditions that necessitates reductions in rates for shorter or longer periods, as an illustration, to enable our grain and other products of the farm to reach foreign markets, which would be impossible in one period unless rates were lowered, whereas in other periods higher rates could be charged without injurious results. Understanding the conditions that surround this complex subject, it is manifest that if a single shipper, or even the Interstate Commerce Commission, is to have the power to prevent at any time that elasticity which involves an advance in rates, the natural result will be that reductions will not be made by the carrier, and the elasticity will be lost. The fear would be ever presented to the mind of the traffic official that the rate once reduced could not--at least, until after exhaustive and long-drawn-out hearings before the commission--be advanced. The necessary fluctuation in rates to meet the changing conditions of commerce, when examined in the light of the reports of the Interstate Commerce Commission, is startling to one not familiar with the rapid change of commercial conditions in this country. There were 225,982 tariff publications filed with the commission in one year, all containing changes of rates, either reductions or increases, and rules governing transportation. These publications--many of them--contained a great number of different tariffs. The Pennsylvania lines, east of Pittsburg, issued 2,200 tariffs and 3,600 supplements. About 33-1/3 per cent of these covered advances, and 66-2/3 per cent were reductions. As the law exists today, there was no special inducement to the shipper to file protests against the advances. Suppose, however, that this amendment had been a part of the act to regulate commerce, how many protests would have been filed, and what length of time would it have taken the commission to have disposed of them? What uncertainty would have resulted to the commercial interests while waiting for the adjudication of these questions? OPPORTUNITY FOR FRAUD AND DISCRIMINATION UNDER THE AMENDMENT. 7. One of the most serious objections urged to the passage of this amendment is the opportunity which such a law would present for the perpetration of frauds under it, and in the case of even honest protest to the advance of rates, where rates rest on a differential basis, in producing thousands of instances of unfair discrimination.
