The sight of the helpless creatures stayed for a moment, even the insensate mob; but the orphans were no sooner out, than the work of demolition commenced. First the main building was gutted, and then set on fire. While it was burning, the large wing adjoining—used as a dormitory—was stripped, inside and out. Several hundred iron bedsteads were carried off—such an exodus of this article was probably never witnessed before. They radiated in every direction for half a mile. Carpets were dragged away at length; desks, stools, chairs, tables, books of all kinds—everything moveable—was carried off. Even the caps and bonnets of the poor children were stolen. While the rioters stripped the building of its furniture, their wives and children, and hundreds who were too cowardly to assist the work of demolition, carried it off. The wing, while burning, swarmed with rioters, who seemed endowed with a demoniacal energy to rend in pieces, rob and destroy. Shutters and doors were torn off and tumbled into the streets. These were seized and torn to pieces almost before they touched the ground, and, with everything else, carried off with surprising celerity. Several persons were injured, and one killed, by the falling of shutters and furniture from the windows. What was very marked as the destruction proceeded, was the absence of excitement. Things were done as coolly by the rioters, as if they were saving instead of destroying property. In the early part of the day the building occupied by the Provost-Marshal, corner of Twenty-eighth street and Broadway, was attacked by a mob, fired, and together with the adjoining buildings, laid in ashes. Mr. John Decker, Chief-engineer of the Fire Department, now made an effort to stay the devouring flames, by addressing himself to the insane mob, and counselling them, as a matter of common sense, to allow the engines to work, and so save the property of those who were entirely innocent of bringing on the draft. At first there seemed a disposition to listen to him, and the engines were got ready, but before they could be set to work, the largest portion of the mob, which had gone tearing down Broadway, learning the firemen’s intentions, came rushing back—howling, cursing, swearing, and vowing vengeance. In less than a minute they cleared the streets, drove the firemen from their engines, stoned the police from the sidewalks, and again took possession of the engines, hose-carriages, etc., which, however, they did not damage. Half an hour later, Chief Decker got his engines at work, and succeeded in eventually saving a part of the building on the corner of Forty-seventh street, the whole of the rest of the block having been destroyed.
