The issue was duly highlighted in a 1907 case in Chicago in which Standard Oil of Indiana was accused of taking illegal rebates from the Chicago and Alton Railroad. The shipments in question had passed between Whiting, Indiana, and East Saint Louis, Illinois, after such rebates were outlawed by the Elkins Act. (Rockefeller, we recall, always insisted that Standard Oil took no rebates after they were banned in 1887.)
