Sunday evening came. Our citizens worshiping in the churches, or in peaceful repose in their own residences, little knew of the imminent peril to which they were exposed, or of the gathering of their fellow citizens in the Invincible Club Hall to arrange the details which, if successful, would bring ruin, desolation and death to thousands of our unsuspecting people. Up the entrance to the hall, cautiously crept the members of the order, peering behind them, and advancing one by one, or in groups of two or three, till they reached the hall. The door was guarded by a sentinel, so that intrusion was out of the question. At nine o'clock, the assemblage was called to order by Obadiah Jackson, Jr., Esq., the Grand Seignior. Patrick Dooley, Secretary, was in his place on the right of the Grand Seignior. The meeting was large, and a more desperate looking collection of men have rarely assembled in a convention in our city. Such desecration of the evening of the Sabbath has never before been witnessed here.

The strangers who were the subject of discussion, were from the counties in the Southern part of the State, and all bore the same general appearance of vagabonds, cut-throats, felons, bounty-jumpers and deserters. They had all seemed to appear simultaneously in our city, unheralded even to the "Sons," and their advent was as much a subject of remark, as would have been a shower of toads and tadpoles. They did not take up their quarters at respectable hotels and private houses, but sneaked away stealthily to the lowest dens of vice, and resorts of criminals unwhipped of justice. They came to help perform infamous work, and had a part of the price of their guilt upon their persons, or had already invested it for the poorest quality of intoxicating liquors. They had been collected together from the various country towns in the Southern part of the State, where they had been in training under the
