Control of air flow is keystone of any ventilating structure, and this feature is obtainable only by installation of mechanically operated fans, together with other ventilating devices such as doors, overcasts, regulators, etc; every mine should be equipped with a fan; metal mines have as great need of efficient circulation of air as have coal mines; general conclusions of author on metal mine ventilation, based upon years of observation.
