It was late in the afternoon when the four of them got off the cable car at Monroe and Dearborn streets and walked leisurely toward their hotel. At one of the street corners they saw a policeman come out of the patrol box and walk rapidly down thestreet. In a moment more he was joined by three other policemen from another street. Uncle turned to watch them, when suddenly they began to run, then faster, almost as in a race. "Sure they're going to arrest somebody," said John, and he started after them at break-neck speed with visions of a murder probably being done just around the corner. Uncle became excited also and started after them followed by Aunt and Fanny, not knowing what else to do. Uncle and John reached the corner breathless and looked each way to see where the robbery or murder was being done, but what was their disgust to see the three policemen climbing into a cable car and calmly taking a seat. It was an outrageous sell on all of them, but it could not be helped, and there was no law by which they could sue the policemen for a false alarm. They had the right to run to catch a car if they wanted to. The family went on more deliberately now for they had no breath to spare and there was but little to be said. Uncle felt that Chicago was very much of a mockery anyhow. But he had seen enough to make him desire to see more. The tremendous puffing and blowing of a tug was heard somewhere in the river and they concluded to go over to the bridge and see what it was. There was a mystery anyway about how those big boats got past the bridges.
