Ordinary fire extinguishers such as chemicals and water applied to a magnesium fire only make it burn more intensely. A black powder developed by a commercial chemical firm will do the trick, however, and this picture shows one of the technicians demonstrating how to use it at the Michigan Fire college at the University. Demonstrations are held each afternoon during the school this week.

Training firemen are receiving at the Michigan Fire college being conducted by the University extension service this week includes testing ladders so firemen will know when they're safe when needed. Sandbags are placed on a suspended ladder as pictured above, and the amount of sag is measured. A few months later, the process is repeated, and if the sag is considerably higher, the ladder is considered unsafe.
