From the time the Central Association announced itself, independent refiners and the producers as a body watched developments with suspicion. They had little to go on. They had no means of proving what was actually the fact that the Central Association was the Standard Oil Company working secretly to bring its competitors under control or drive them out of business. They had no way of knowing what was actually the fact that the Standard had contracts with the Central, Erie and the Pennsylvania which gave them rebates on the lowest tariff which others paid. That this must be the case, however, they were convinced, and they determined early in 1876 to call on Congress for another investigation. A hearing was practically insured, for Congress since 1872 had given serious attention to the transportation troubles. The Windom Committee of 1874 had made a report, the sweeping recommendations of which gave much encouragement to those who suffered from the practices of the railroads. Among other things this committee recommended that all rates, drawbacks, etc., be published at every point and no changes allowed in them without proper notification. It recommended the Bureau of Commerce which, in 1902, twenty-eight years later, was created. So serious did the Windom Committee consider the situation in 1874, that it made the following radical recommendations: The only means of securing and maintaining reliable and effective competition between railways is through national or state ownership, or control of one or more lines which, being unable to enter into combinations, will serve as a regulation of other lines. One or more double-track freight-railways honestly and thoroughly constructed, owned or controlled by the government, and operated at a low rate of speed, would doubtless be able to carry at a much less cost than can be done under the present system of operating fast and slow trains on the same road; and, being incapable of entering into combinations, would no doubt serve as a very valuable regulator of existing railroads within the range of their influence.
