They did not propose to commit any violence, but having begun their investigations they were determined to go through with them. The Mayor and the Governor seemed to have an unaccountable repugnance to the use of force, and let the mob depart for Columbia College without any resistance. The professors and students were amazed at this sudden inundation of the crowd, who swarmed without opposition through every part of the building. Finding nothing to confirm their suspicions, they left without doing any material injury. Still unsatisfied, however, they repaired to the houses of the neighboring physicians, and the leaders, acting as a delegation of the crowd, went through them with the same result. It was a singularly well-behaved mob, and they received the report of the self-constituted committees with apparently perfect satisfaction, and when they had made the round of the houses, gradually broke up into knots and dispersed. But the lawless spirit of a mob seldom arrests and controls itself. Having once felt its strength and power, it is never satisfied till it measures them against those of the legal authorities, and yields only when it must. Hence, as a rule, the quicker "it feels the strong hand of power" the better for all parties. Promising legal satisfaction, to law-breakers is a very unsatisfactory proceeding. Obedience first and discussion afterwards is the proper order to be observed. The Mayor had hardly time to congratulate himself on having overcome so easily a serious difficulty, before he found that he had not as yet touched it. In the afternoon, the crowd again began to assemble, and this time around the jail, with the avowed purpose of taking vengeance on the students and physicians locked up there for safe-keeping. Having asserted and exercised, against all law, the right of domiciliary visits, it was but a short and easy step to assert the right to punish also contrary to law. As they gathered in front of the jail, it was seen that a different spirit from that which they had hitherto exhibited ruled them. The tiger was unchained, and loud shouts and yells were heard. "Bring out your doctors! bring out your doctors!" arose on every side. They threatened to tear down the building unless they were given up. The inmates became thoroughly alarmed, and barricaded the doors and windows, and armed themselves the best way they could for self-defence. Attempts were made to parley with the crowd, but they would listen to nothing, and answered every appeal with loud shouts for the doctors. What they _intended_ to do with them by way of punishment was not so clear, though what their fate would have been, if once at their mercy, there was little doubt. The city authorities now became alarmed, murder was imminent, and having no police force sufficient to cope with such a formidable mob, they decided that the city was in a state of insurrection, and called out the military. About three o'clock, the
