The percentage of the total population contained in Melbourne and its suburbs rose from 26 in 1861 to 43 in 1891, mainly as the result of the high protective tariff which aimed at making Victoria the principal manufacturing centre of Australia. Upon the consequent establishment of a large number of factories, the Government were soon compelled to intervene in the interests of the workers, and passed in 1873 the first Act dealing with the supervision of factories and workrooms. It defined a factory as any place in which not less than ten persons were employed in manufacturing goods for sale, and provided that such places should be subject, as to building, sanitation, &c., to regulations made by the central Board of Health, and that no female should be employed therein without the permission of the Chief Secretary for more than eight hours in any one day. The measure failed in its purpose through the indifference of the Municipalities, which were charged with its entire administration. They appear to have been negligent in exercising the powers entrusted to them, and to have allowed themselves to be served by officers who were unacquainted with their duties. In the following years several measures were passed which { 133} were consolidated by the Factories and Shops Act of 1890. Some new points of great importance had been introduced, which applied, however, only to cities, towns, and boroughs, unless they were extended to any shire at the request of its Council: the definition of a factory was amended so as to include all places in which four white men or two Chinamen were employed in manufacturing goods for sale; such places had to be registered, subject to the approval of the premises by the Local Council, and the employers were bound to keep a record showing the names of the persons employed in the factory, the sort of work done by them, and the names and addresses of outside workers; the employment of children under thirteen years of age was prohibited; machinery had to be fenced in in order to prevent accidents, and persons in charge of steam-engines and boilers, with a few exceptions, had to obtain certificates of competency. As regards the enforcement of these and other provisions, inspectors were authorised to enter a factory at any reasonable time, to make any pertinent inquiry and examination, to demand the production of any certificate or documents kept in pursuance of the Act, and, generally, to exercise such other powers as might be necessary for carrying it into effect. Proceedings for offences against the Act were to be taken before two or more justices, who, upon a conviction, would be guided by a prescribed scale of fines and penalties. Finally, retail shops were { 134} dealt with by a provision which limited the hours during which they might be kept open; but certain categories of shops were explicitly excluded, and Municipal Councils were given the power of altering the hours upon a petition of a majority of the shopkeepers.
