I trust use of United States troops will not be necessary. If it becomes necessary, they will be used promptly and decisively upon the justifying facts being certified to me. In such case, if practicable, let Walker and the marshal and United States judge join in statement as to the exigency. A few hours afterward the following urgent and decisive despatch from the marshal, endorsed by a judge of the United States court and the district attorney and special counsel, was received by the Attorney-General. CHICAGO, ILL., July 3, 1894. Hon. RICHARD OLNEY, _Attorney-General_, Washington, D. C.: When the injunction was granted yesterday, a mob of from two to three thousand held possession of a point in the city near the crossing of the Rock Island by other roads, where they had already ditched a mail-train, and prevented the passing of any trains, whether mail or otherwise. I read the injunction writ to this mob and commanded them to disperse. The reading of the writ met with no response except jeers and hoots. Shortly after, the mob threw a number of baggage-cars across the track, since when no mail-train has been able to move. I am unable to disperse the mob, clear the tracks, or arrest the men who were engaged in the acts named, and believe that no force less than the regular troops of the United States can procure the passage of the mail-trains, or enforce the orders of the courts. I believe people engaged in trades are quitting employment to-day, and in my opinion will be joining the mob to-night and especially to-morrow; and it is my judgment that the troops should be here at the earliest moment. An emergency has arisen for their presence in this city. J. W. ARNOLD, _United States Marshal_. We have read the foregoing, and from that information, and other information that has come to us, believe that an emergency exists for the immediate presence of United States troops. P. S. GROSSCUP, _Judge_. EDWIN WALKER, } THOMAS E. MILCHIST,} _Attys_. In the afternoon of the same day the following order was telegraphed from army headquarters in the city of Washington: WAR DEPARTMENT, HEADQUARTERS OF THE ARMY. WASHINGTON, D. C., July 3, 1894, 4 o’clock P.M. TO MARTIN, _Adjutant-General_, Headquarters Department of Missouri, Chicago, Ill.
