inspector shall demand and be furnished with proof of such child's age by the production of a verified baptismal certificate or a duly attested birth certificate, or, in case such certificates cannot be secured, by the record of age stated in the first school enrollment of such child. Whenever it appears that a permit was obtained by wrong or false statements as to any child's age, the officer who granted such permit shall forthwith revoke the same. After having received, examined and placed on file such papers, the officer shall issue to the child a permit and badge. The principal or chief executive officer of schools, in which children under fourteen years of age are pupils, shall keep a complete list of all children in their school to whom a permit and badge has been issued, as herein provided.
