Mr. Crowley, the Superintendent of the Telegraph Bureau, was made acquainted early, Monday, by mere accident with this plan of the rioters. Coming to town in the Third Avenue cars from Yorkville, where he resided, he suddenly found the car arrested by a mob, and getting out with the other passengers, discovered men chopping furiously away at the telegraph poles; and without stopping to think, rushed up to them and ordered them to desist. One of the ruffians, looking up, cried out, "he is one of the d--d operators." Instantly yells arose, "Smash him," "Kill him," when those nearest seized him. By great adroitness he disarmed their suspicions sufficiently to prevent further violence, though they held him prisoner for an hour. At last, seeing an opportunity when more important objects attracted their attention, he quietly worked his way out and escaped. CHAPTER XIII.

In the meantime, the mob that stood watching the spreading conflagration in Third Avenue increased rapidly, fed by tributaries from the tenement-houses, slums, and workshops in that vicinity. But they were soon startled from their state of comparative quietness, by the cry of "the soldiers are coming." The Invalid Corps, a small body sent from the Park, was approaching. As it came up, the soldiers fired, either blank cartridges, or over the heads of the crowd, doubtless thinking a single discharge would disperse it. The folly of such a course was instantly shown, for the mob, roused into sudden fury, dashed on the small body of soldiers before they could reload, and snatching away their muskets, pounded them over the head, and chased them like sheep for ten blocks. One soldier was left for dead on the pavement, beaten to a jelly. Another, breaking from the crowd, attempted to climb some rocks near Forty-second Street, when his pursuers grabbed him and dragged him to the top, where they tore off his uniform, and beat him till he was senseless, and then threw him down to the bottom and left him.
