Section 3. That no minor under the age of sixteen years shall be employed, permitted or suffered to work, inside any coal-mine, and no minor under the age of sixteen years shall be employed in or about or for any establishment or industry named in section one of this act, unless the employer of said minor procures and keeps on file, and accessible to the mine inspector, the employment certificate as hereinafter provided, issued to said minor, and keeps two complete lists of all minors under the age of sixteen years employed in or for his or her establishment; one of said lists to be kept on file in the office of the employer, and one to be conspicuously posted in each of the several departments in or for which minors are employed. Said employment certificate, when issued, shall be the property of the minor named therein, who shall be entitled to a surrender of said certificate to him or her by the employer whenever said minor shall leave the service of any employer holding said certificate. In case a minor, who is employed or permitted to work in or about or for any establishment or industry named in section one of this act, as being sixteen years of age or over, appears to the Chief of the Department of Mines or any mine inspector to be under the age of sixteen years, said Chief of the Department of Mines or mine inspector shall make written demand that the employer of said minor shall procure and keep on file in the office of such establishment, subject to inspection, the same evidence that said minor is in fact sixteen years of age or over as is required as evidence of age for the issuance of the employment certificates hereinafter provided for; and the employer furnishing such evidence shall not be required to furnish any further evidence of the age of said minor. In case the evidence of age, for which demand is so made, be not filed as hereinbefore required, within thirty days after said demand, the employer shall cease to employ the minor named in said demand or to permit said minor to work: Provided, however, That said employer, by thus ceasing to employ or permit said minor to work, shall not be relieved from any of the penalties provided in this act for the employment of a minor under the age of sixteen years without the filing for such minor of the employment certificate hereinbefore required.
