Horner states in the same report that in many factories labourers are not warned when machinery is about to be started up. Since there is always something to be done about machinery even when it is not operating, fingers and hands are always occupied with it, and accidents happen continually due to the mere omission of a warning signal (loc. cit., p. 44). The manufacturers had a trades-union at the time to oppose factory legislation, the so-called National Association for the Amendment of the Factory Laws in Manchester, which in March 1855 collected more than £50,000 by assessing 2 shillings per horse-power, to pay for the court proceedings against its members started by factory inspectors, and to conduct the cases in the name of the union. It was a matter of proving that killing was no murder [Allusion to the pamphlet 'Killing no Murder' which appeared in England in 1657. Its author was the leveller Edward Sexby. — Ed.] when it occurred for the sake of profit. A factory inspector for Scotland, Sir John Kincaid, tells about a certain firm in Glasgow which used the iron scrap at its factory to make protective shields for all its machinery, the cost amounting to £9 1s. Joining the manufacturers' union would have cost it an assessment of £11 for its 110 horse-power, which was more than the cost of all its protective appliances. But the National Association had been organised in 1854 for the express purpose of opposing the law which prescribed such protection. The manufacturers had not paid the least heed to it during the whole period from 1844 to 1854. When the factory inspectors, at instructions from Palmerston, then informed the manufacturers that the law would be enforced in earnest, the manufacturers instantly founded their association, many of whose most prominent members were themselves justices of the peace and in this capacity were supposed to enforce the law. When in April 1855 the new Minister of the Interior, Sir George Grey, offered a compromise under which the government would be content with practically nominal safety appliances the Association indignantly rejected even this. In various lawsuits the famous engineer William Fairbairn threw the weight of his reputation behind the principle of economy and in defence of the freedom of capital which had been violated. The head of factory inspection, Leonard Horner, was persecuted and maligned by the manufacturers in every conceivable manner.
