As the situation grew more and more dangerous, the President directed the head of the Federal Labor Bureau to make an investigation of the whole matter. From this investigation it appeared that the most feasible solution of the problem was to prevail upon both sides to agree to a commission of arbitration and promise to accept its findings. To this proposal the miners agreed; the mine owners insolently declined it. Nevertheless, Roosevelt persisted, and ultimately the operators yielded on condition that the commission, which was to be named by the President, should contain no representative of labor. They insisted that it should be composed of (1) an officer of the engineer corps of the army or navy, (2) a man with experience in mining, (3) a "man of prominence, eminent as a sociologist," (4) a Federal Judge of the Eastern District of Pennsylvania, and (5) a mining engineer. In the course of a long and grueling conference it looked as though a deadlock could be the only outcome, since the mine owners would have no representative of labor on any terms. But it suddenly dawned on Roosevelt that the owners were objecting not to the thing but to the name. He discovered that they would not object to the appointment of any man, labor man or not, so long as he was not appointed as a labor man or as a representative of labor. "I shall never forget," he says in his "Autobiography", "the mixture of relief and amusement I felt when I thoroughly grasped the fact that while they would heroically submit to anarchy rather than have Tweedledum, yet if I would call it Tweedledee they would accept with rapture." All that he needed to do was to "commit a technical and nominal absurdity with a solemn face." When he realized that this was the case, Roosevelt announced that he was glad to accept the terms laid down, and proceeded to appoint to the third position on the Commission the labor man whom he had wanted from the first to appoint, Mr. E. E. Clark, the head of the Brotherhood of Railway Conductors. He called him, however, an "eminent sociologist," adding in his announcement of the appointment this explanation: "For the purposes of such a Commission, the term sociologist means a man who has thought and studied deeply on social questions and has practically applied his knowledge." The Commission as finally constituted was an admirable one. Its report, which removed every menace to peace in the coal industry, was an outstanding event in the history of the relations of labor and capital in the United States.
