When these same men were at their homes they did not dare to openly say a word in favor of Anarchy, because they were few in numbers; but should there be enough to make a formidable showing, they will throw off their mask and assume a defiant, menacing attitude. These arrivals, just as soon as they became known, were kept under espionage, and every movement they made was looked after, lest they might commit some desperate deed. Of course there were a great many whom the police did not discover, and it is a wonder that, during the excitement incident to the arrest of so many Anarchists and the searches made of Anarchistic houses, some diabolical act was not perpetrated. Possibly they discovered that the omnipresent police were so thoroughly on the inside of their conspiracy that detection was inevitable. It is certain that they knew that I had become thoroughly posted as to the inside workings of Anarchy, and the sound fear which I was able to inspire by a bold and aggressive policy no doubt acted as a restraint upon any violent outburst of passion and revenge. It was constant vigilance alone that averted trouble, and no Anarchist of a specially vicious disposition was permitted to feel that his movements were overlooked or unwatched. For this purpose I had Anarchists among Anarchists to inform on Anarchists, and all the meetings were thus kept under strict surveillance. Even private houses were watched. On one occasion I desired to secure certain information. One of the private detectives was accordingly detailed to watch the rear of a certain building from an alley. He was there for two days without being observed by any one, but on the third day he was noticed by a police officer. The officer asked him what he was doing in that locality, and the private responded: “I am waiting for a friend of mine who is working in this barn, and I expect him around soon.” [Illustration: THALIA HALL. From a Photograph.] The officer placed no reliance on the statement, and so he hustled him out of the alley. The detective walked on a short distance, and, as soon as the officer was out of sight, retraced his steps and returned to the place, this time finding a different point for his observations. He had scarcely thought himself secure from further interruptions, when the back gate of the next yard opened, and in walked the same officer. Both were alike surprised. But this time there were no questions asked and no explanations demanded. The officer promptly seized the detective by the collar and marched him to the Chicago Avenue Station. The detective kept his identity to himself, and of course found himself speedily assigned to a cell over night. On the next morning, as I sauntered through the lock-up, I discovered my friend in durance vile, and, promptly looking up the record, found that he had been booked for disorderly conduct.
