Towards evening a mob assembled over in Ninth Avenue, and went to work with some system and forethought. Instead of wandering round, firing and plundering as the whim seized them, they began to throw up barricades, behind which they could rally when the military and police came to attack them. Indeed, the same thing had been done on the east side of the city; while railroads had been torn up, and stages stopped, to keep them from carrying policemen, rapidly from one quarter to another. During the day, Colonel Frothingham had stood in Third Avenue, and stopped and emptied every car as it approached, and filled it with soldiers, to be carried to the upper part of the city. Acton, too, had sent round to collect all the stages still running in Broadway and the Bowery, and in a short time they came rumbling into Mulberry Street, forming a long line in front of head-quarters. A telegram from Second Avenue demanded immediate help, and the police were bundled into them and hurried off. One driver refused to stir, saying, roughly, he was not hired to carry policemen. Acton had no time to argue the case, and quickly turning to a policeman, he said: "Put that man in cell Number 92." In a twinkling he was jerked from his seat and hurried away. Turning to another policeman, he said: "Mount that box and drive." The next moment the stage, with a long string of others, loaded inside and out with the bluecoats, was whirling through the streets. He had done the same with the Sixth Avenue cars. The son-in-law of George Law remonstrated, saying that it would provoke the mob to tear down the railroad buildings. There was no time to stand on ceremony; the cars were seized, and the company, to save their property, paid a large sum to the ringleaders of the rioters. In fact, a great many factories and buildings were bought off in the same way; so that the leaders drove quite a thriving business.
