About January, 1887, one of my privates informed me that there was a place on Clybourn Avenue where the Anarchists were accustomed to hold private meetings. He said that he could not get in as yet, and I told him to pick up some one whom he could work handily. He must first form the man’s acquaintance, and then hang around the saloons in the neighborhood and read the _Arbeiter-Zeitung_. I gave him one of John Most’s books and made him wear a red necktie. I advised him also to get about half drunk, sing the Marseillaise and curse the police. By so doing, I told him, it would not be long before he would find a partner. Several times subsequently the detective visited the Anarchist resorts, accompanied by a little boy who belonged to one of his friends, and in less than two weeks he had wormed himself into the confidence of the gang who frequented Clybourn Avenue. If any one asked him his name he would say: “I don’t give my name to people I don’t know. I am against law and order, and that is sufficient. I don’t believe in having good men hung to satisfy the rich. They will not hang if I can help any.” For the first couple of weeks, the newly formed friends of this detective would not take him to any of their meetings. I advised him not to make inquiries. As soon as they thought him all right, they would speak themselves. Within three weeks some one took him to a meeting and vouched for him as being true to their cause. At the first meeting he attended he saw that he was as intelligent as any one of them, and so he delivered a short speech. That captured them, and they pronounced him a good man. They asked him to call again at their next meeting, and he promised that he would be on hand. He then reported to me. I told him to find a weak spot around the building, where I could put some one to protect him in case of discovery and danger. A few days after he reported again that there was a vacant basement under the house, and that it was very low. There was only a common door with an ordinary lock. I then promised him that I would put a strong man in there at every meeting, and in case he should be attacked by the gang, he should shout, “Police.” Then, the moment the door was broken in, he was to cry out, “Brother!” so that the man coming to his assistance would know him at once. I also told him that at the next meeting he should ascertain the size of the room and notice whatever furniture might be there and where it was standing. This he did. He made a small diagram.
