Some of the anarchists indicted for conspiracy turned State's evidence. Gottfried Waller, a Swiss by nationality, a cabinet-maker by trade, formerly a socialist, and a member of the Lehr and Wehr Verein, testified that the latter organization comprised various armed groups of anarchists; that the letter "Y" in the _Arbeiter Zeitung_ meant for the armed section to meet at Greif's hall; that he acted as chairman of the meeting of seventy or eighty persons, Engel, Fischer and Breitenfeld, the commander of the Lehr and Wehr, being present. The witness testified that Engel unfolded a plan whereby if a collision between the strikers and the police should occur, the word "Ruhe" would appear in the _Arbeiter_ as a signal for the Lehr and Wehr and the Northwest group of anarchists to assemble in Wicker Park with arms. They should then storm the North avenue police station, and proceed thence to other stations, using dynamite and shooting down all who opposed them, and should cut the telegraph wires to prevent communication with the outside world. Engel said the best way to begin would be to throw a dynamite bomb into the police station, and that when the populace saw that the police were overpowered, tumult would spread through the city, and the anarchists would be joined by the working men. This plan, Engel said, had been adopted by the Northwest group. It was decided to appoint a committee to keep watch of affairs in the city and to call a meeting for the next night in the Haymarket. Fischer was directed to get the handbills calling the meeting printed. Those present at the preliminary meeting represented various groups throughout the city. Fischer announced that the word "Ruhe" would mean that a revolution had been started. Engel put the motion, and the plan was adopted. The committee on action was composed of members from each group; the witness knew only one--Kraemer. The members of the armed groups were known by numbers, and witness number was 19. Spies was questioned in January, 1885, at Grand Rapids, Mich., relative to these secret organizations, when he said that force must bring about the necessary reform which the ballot-box had failed to inaugurate and was incompetent to perform. Shook, of Grand Rapids, also testified that Spies had said that the secret drilled organizations of Chicago for the revolution of society numbered over 3,000, and that none except members of those organizations knew of the _modus operandi_ by which they intended to wage their warfare.
