A FLINT-AND-STEEL OUTFIT, AND A MINER'S STEEL MILL 



The upper picture shows a flint-and-steel outfit, the implements for lighting a fire before 

 the days of matches. The lower picture shows a miner's steel mill, which was used for giving 

 light in mines before the day of the safety-lamp. It consists of a steel disk which is rotated 

 rapidly against a piece of flint, producing a stream of sparks. It was thought that such sparks 

 would not ignite fire-damp a belief which is now known to be erroneous.
