The "crooked" gambling "trust" in Chicago spread over the civilized world, had its clutches on nearly every United States battleship, army post and military prison; caused wholesale desertions, and in general corrupted the entire defensive institution of the nation. TRY TO CORRUPT SCHOOLBOYS. Besides the corruption of the army, these companies are said to have aimed a blow at the foundation of the nation by offering, through a mail order plan, for six cents, loaded dice to schoolboys, provided they sent the names of likely gamblers among their playmates. This plan had not reached its full growth when nipped. But the disruption of the army and navy had been under way for several years and had reached such gigantic proportions that the military service was in danger of complete disorganization. Thousands of men were mulcted of their pay monthly. Desertions followed these wholesale robberies. The war department could not find the specific trouble. Post commanders and battleship commanders were instructed to investigate. The army investigation, confirmed after the raid and arrests, showed that the whole army had been honeycombed with corruption by these companies. Express books and registered mail return cards showed that most of the goods were sold to soldiers and sailors. DETECTIVE WOOLDRIDGE SECURES EVIDENCE IN NOVEL WAY. In August, 1890, complaints had been made at the Stanton Avenue Police Station for several weeks concerning the establishment of a disorderly house at 306 Thirty-first street, but try as they would uniformed officers were helpless so far as securing evidence enough to convict was concerned. Wooldridge at that time a uniformed man, was put in plain clothes and detailed on the case. One of the great stumbling blocks in the way of the police had been the high basement under the house, which made it impossible for any one to look in the windows of the flat without the aid of the ladder. As the presence of a ladder would arouse suspicion, the problem of viewing the inside of the flat was a difficult one. One thing the other men on the case had overlooked. This was the presence of a beam jutting out from the top of the building to which a rope, pulley, and barrel were attached, used as a means of lowering garbage and ashes from the second floor to the alley. Wooldridge saw the possibilities of the rope and barrel trick. Attaching to the rope a vinegar barrel with holes bored in it at convenient intervals, he awaited an opportune time, curled up in the barrel, and had himself drawn up to the level of the windows by two officers. The lowering and raising of the barrel being a customary thing in the building, excited no suspicion in the minds of those in the flat, and Wooldridge, with his sleuth's eye at one of the holes, saw what served to drive the place out of existence and secure the conviction of its keeper.
