Laws enacted for the purpose of regulating the hours of work, and the sanitary condition, and preserving the health and morals, of the employes, and promoting the education of young persons employed at such labor. The statute of 1802 (42 Geo. III. c. 73) was the first to be passed, and was followed by those of 1833, and others allowing at brief intervals up to 1883. For a detailed account of the English acts, see In- ternational Cyclopedia, h. t. In this country statutes have been passed from time to time in most if not all the states, having in view the same reformatory purpose or kindred ones, as the English Factory Act of 1883 and the others of like character which followed it. The right of the states to pass such acts is sustained under the police power and the principles by which the validity of any such legislation is to be tested is thus stated by the most recent writer on the subject of labor law: "Such statutes are doubtless constitutional in any case where the reason of the regulation is based upon consideration of the public health, safety, and comfort, or the health and morals of the operatives, and is apparent on the face of the statute, but it will not do, under the guise of police regulation, to pass statutes of which the real purpose is different, even though they be in the interest of any particu- lar trade, or otherwise desirable. Such regulations or reformations can only be attained by combination among the workmen themselves to see that they are complied with." Stimson, Lab. L. of U. S. $ 45. The most important subjects covered by this leg- islation are summarized by the same author: "The preservation of the health of employes in factories by the removal of excessive dust, or for securing pure air, or requiring fans or other special devices to remove noxious dust or vapors peculiar to the trade; statutes requiring guards to be placed about dangerous machinery, belting, elevators, wells, air- shafts, etc.; statutes providing for fire-escapes, ade- quate staircases with rails, rubber treads, etc.; doors opening outwardly, etc.; statutes providing against injury to the operatives by the machinery used, such as laws prohibiting the machinery to be cleaned while in motion, or from being cleaned by any woman or minor; laws requiring mechanical belt-shifters, etc., or connection by bells, tubes, etc., between any room where machinery is used and the engine-room; laws aimed at overcrowding in facto- ries, and at the general comfort of the operatives; and many special laws in railways, mines, and other special occupations, such as the laws requiring warning guards to be placed before bridges upon railroads, requiring the frogs and switches or other appliances of the track to be in good condition and properly protected by timber or otherwise, provid- ing automatic couplings to both freight and pas senger trains, and, in building trades, providing for rallings upon scaffolds and for suitable scaffolds generally. Id. There are in many of the states restric- tions upon the employment of women and children by limiting the number of hours of labor permitted and providing for over- sight of their treatment. For details of such legislation in various states, see id. § 13. It is held constitutional as to minors without doubt, resting on the theory that the state is parens patriæ, and as such en- titled to the control of those who are un- able to contract for themselves. The effort is made to rest it on the same ground as to women; 120 Mass. 383 (in which state there is an unusual and extensive constitutional power of legislation "for the good and welfare," of the people); but elsewhere the constitutionality of such acts has been lately denied on the ground that it was class legislation; 155 Ill. 98. It is now earnestly contended that under the modern view of women under the law, as equally capable with men of contracting, and often of voting and holding office, any effort to restrict the freedom of women to contract cannot be sustained; Stimson, Lab. L. § 13. But while we may admit the full force of the argument against this class of legisla- tion based upon the changed legal relations of women, it may nevertheless be doubted whether it does not to some extent, at least. miss the real underlying principle of such legislation. It is intended for the protec- tion of women and the amelioration of their condition, and is more or less a recognition of the different physical constitution of woman and her peculiar and important re lation to the community. Such considera- tions rest upon conditions which are not changed by any increase of her property rights or political privileges, and, so far as they may have been the basis of these re- strictive regulations, they exist and operate with undiminished force. They are appar- ently overlooked by courts and text writers, including the author quoted, but must un- doubtedly be reckoned with in any attempt to deal properly either with the validity or the policy of the
