The laws as to labor in mines are naturally more severe; although in some they are covered by the ordinary factory laws (Colorado, Florida, Iowa, Kansas, Kentucky, Louisiana, Michigan, Minnesota, North Dakota, Oregon, South Carolina, South Dakota, Tennessee, Vermont, Virginia, Wisconsin). Female labor is absolutely forbidden in mines or works underground in Alabama, Arkansas, Illinois, Indiana, Missouri, New York, North Carolina, Oklahoma, Pennsylvania, Utah, Washington, Wyoming, and West Virginia,—in short, in most of the States except Idaho, Kansas, Iowa, Kentucky, Virginia, Wyoming, where mines exist; and the limit of male labor is usually put at from fourteen. (Alabama, Arkansas, Idaho, Indiana, Missouri, Ohio,[1] South Dakota, Tennessee, Utah, Wyoming) to sixteen (Illinois, Missouri,[2] Montana, New York, Oklahoma, Pennsylvania, Washington); or twelve (North Carolina, South Carolina, West Virginia), even in States which have no such legislation as to factories.
