The history of the Sherman Act has absolutely justified the wisdom and integrity of the Supreme Court. Scores of times the lower courts have decided against the government; and the most important decisions have been those in which the Supreme Court has reversed the inferior tribunals. The record of federal prosecutions under this law affords an interesting insight into the attitude of the several administrations toward trust regulation. President Harrison, under whose administration the law was passed, accomplished little. His attorney-general brought seven actions--four bills in equity and three criminal indictments. Under the equity proceedings, he obtained three injunctions; the criminal proceedings all ended in failure. One of the cases instituted by President Harrison, however,--that against the Trans-Missouri Freight Association,--was afterward taken to the Supreme Court by President Cleveland's attorney-general, and resulted in securing one of the most important decisions in the history of the law. President Cleveland showed considerably more activity than his predecessor. Though only eight proceedings stand to his credit, several of them were of the greatest importance. He used the Sherman Law in fighting the Debs cases growing out of the Pullman strike; and in the well-known Addyston Pipe & Steel Company case he dissolved a combination, formed by several manufacturers of gas and sewer pipe, to monopolize the trade of most large American municipalities. President McKinley apparently had little interest in the Sherman Law; throughout his four and a half years only three cases were prosecuted, none of which were of much consequence. With the administration of President Roosevelt, however, the situation changed. Against the seven cases instituted by Harrison, the eight by Cleveland, the three by McKinley, stand thirty-seven started by Roosevelt. That is, he has instituted twice as many cases as all his predecessors combined, and many of the Roosevelt prosecutions have proved successful. Nineteen of these thirty-seven cases have already been decided; the government has won seventeen and lost only two.
