IT was not difficult to locate the moral responsibility for the bold and bloody attack on law and authority. The seditious utterances of such men as Spies, Parsons, Fielden, Schwab and other leaders at public gatherings for weeks and months preceding the eight-hour strike, and the defiant declarations of such papers as the _Arbeiter-Zeitung_ and the _Alarm_, clearly pointed to the sources from which came the inspiration for the crowning crime of Anarchy. It was likewise a strongly settled conviction that the thrower of the bomb was not simply a Guiteau-like crank, but that there must have been a deliberate, organized conspiracy, of which he was a duly constituted agent. In the work, therefore, of getting at the inside facts, the points sought were: What was the exact nature of that conspiracy, and who constituted the chief conspirators? The possession of every detail in connection with these two points was absolutely necessary in order to fix the criminal responsibility, and to the solution of this problem the officers bent all their energies. The detectives were well aware that the office of the _Arbeiter-Zeitung_ had been the headquarters for the central, controlling body of the Anarchist organizations in Chicago, and on the morning following the explosion Inspector Bonfield determined to raid the establishment and bring in such of the leaders as might be found there. Several detectives were assigned to this duty, and they soon returned, having under arrest August Spies, his brother Chris, Michael Schwab and Adolph Fischer. These were locked up at the Central Station. Shortly thereafter fifteen or sixteen compositors of the paper were arrested and brought to the same place. They were a meek-looking set, and were visibly moved with fear. Immediately after 12 o’clock, State’s Attorney Grinnell, Assistant State’s Attorney Furthmann, Lieut. Joseph Kipley, Lieut. John D. Shea, Detectives James Bonfield, Slayton, Baer, Palmer, Thehorn and several other officers repaired to the _Arbeiter-Zeitung_ building and made a most thorough search of every room in the premises. A lot of manuscript was found on hooks attached to the printers’ cases, and this was carefully wrapped up and taken away. The files of the _Arbeiter-Zeitung_ and _Alarm_ were also piled into a wagon and carted to the Central Station. [Illustration: ADOLPH FISCHER. From a Photograph taken by the Police.]
