The night watchman, who had charge of the engine and smallgenerator it operated for lighting purposes when the balance ofthe plant was idle, was said to have been making his clock-punch-ing tour of the mill, when he heard a considerable noise as of anexplosion, followed by failing of the electric lights; so it is notpossible to determine which of several possible causes was pri- 240 THE LOCOMOTIVE [October,.

However, the engine governorwas of the throttling type, which was fully described in a paperon Prevention of Fly Wheel Explosions, which appeared in TheLocomotive of July, 1915. There are two kinds ofthrottling governors, onetermed the automatic, andthe second the non-auto-matic. The former will, andthe latter will not, preventthe cylinder from obtainingsteam, should the governorbelt break or fall from thethe governor pulley. Thegovernor of the engine inquestion was of the non-automatic type, and it ispossible the accident wasdue to the governor beltleaving the pulley, whichwould give the cylinder full steam pressure, and under the light load condition, would causeover-speeding, which would require but a few seconds to bring thewheel up to a disrupting speed. ? The engine was so completely wrecked that it would seem theremust have been other contributing causes, and as one of the studbolts holding the co
