That these Unions contribute greatly to nourish the bitter hatred of the workers against the property-holding class need hardly be said.  From them proceed, therefore, with or without the connivance of the leading members, in times of unusual excitement, individual actions which can be explained only by hatred wrought to the pitch of despair, by a wild passion overwhelming all restraints.  Of this sort are the attacks with vitriol mentioned in the foregoing pages, and a series of others, of which I shall cite several.  In 1831, during a violent labour movement, young Ashton, a manufacturer in Hyde, near Manchester, was shot one evening when crossing a field, and no trace of the assassin discovered.  There is no doubt that this was a deed of vengeance of the working-men.  Incendiarisms and attempted explosions are very common.  On Friday, September 29th, 1843, an attempt was made to blow up the saw-works of Padgin, in Howard Street, Sheffield.  A closed iron tube filled with powder was the means employed, and the damage was considerable.  On the following day, a similar attempt was made in Ibbetson’s knife and file works at Shales Moor, near Sheffield.  Mr. Ibbetson had made himself obnoxious by an active participation in bourgeois movements, by low wages, the exclusive employment of knobsticks, and the exploitation of the Poor Law for his own benefit.  He had reported, during the crisis of 1842, such operatives as refused to accept reduced wages, as persons who could find work but would not take it, and were, therefore, not deserving of relief, so compelling the acceptance of a reduction.  Considerable damage was inflicted by the explosion, and all the working-men who came to view it regretted only “that the whole concern was not blown into the air.”  On Friday, October 6th, 1844, an attempt to set fire to the factory of Ainsworth and Crompton, at Bolton, did no damage; it was the third or fourth attempt in the same factory within a very short time.  In the meeting of the Town Council of Sheffield, on Wednesday, January 10th, 1844, the Commissioner of Police exhibited a cast-iron machine, made for the express purpose of producing an explosion, and found filled with four pounds of powder, and a fuse which had been lighted but had not taken effect, in the works of Mr. Kitchen, Earl Street, Sheffield.  On Sunday, January 20th, 1844, an explosion caused by a package of powder took place in the sawmill of Bently & White, at Bury, in Lancashire, and produced considerable damage.  On Thursday, February 1st, 1844, the Soho Wheel Works, in Sheffield, were set on fire and burnt up.
