The last aim of protection of health--the exclusion of such injurious methods of working as may be replaced by non-injurious methods in all industrial work, and for male workers as well as for women and children--must be attained by progressive extension of that administrative protection to which the _von Berlepsch_ Bill opens the way for quasi-factory labour (Sec. 154). It would be difficult to carry out in any other way the Auer Motion, for the "prohibition of all injurious methods of working, wherever non-injurious methods are possible." The general principle of prohibition might be laid down by law, and the enforcement of such prohibition, by order of a Supreme Central Bureau of Labour Protection, might be left to the control of popular representative bodies and to public opinion. Special legal prohibition, with regard to certain defined industries and methods of work injurious to health, would not be superfluous in addition to general prohibition; such special prohibition is already in force to a greater or less degree. The success of the prohibition in question depends on the good organisation of Labour Protection in matters of technique and health; on the efficiency of local government organs, as well as of the Imperial Central Bureau, and on the impulse given by the more important representative organs of the labouring classes. All these organs need perfecting. Special prohibition needs the assistance of police trade-regulations in regard to instruments and materials dangerous to health. The work that has already been done in the way of protection of morality by prohibition is not to be under-valued, although much still remains to be done. No sufficient steps have as yet been taken to meet that very hateful and insidious evil so deeply harmful to the preservation of national morality, viz. the public sale and advertisement of preventives in sexual intercourse, such as unfortunately so frequently appear in the advertising columns of newspapers, and in shop windows. This is not merely a question of protecting the morality of those engaged in the production and sale of such articles, but also of protecting the morality of the whole nation, maintaining its virile strength, and to some degree also preserving it from the dangers to the growth of population, incidental to an advanced civilisation. The powers at present vested in the police and magistrates to deal with offences against morals would probably be sufficient to stamp out this moral canker that is eating its way even into Labour Protection, without the scandal of legislation. But it is not by ignoring it that this can be accomplished.
