STEAM BOILER EXPLOSIONS. killing the attendant and destroying the boiler-houseand other property. These boilers were horizontal, internally-fired, drop-flue boilers, seven feet diameter and twenty-one feetlong, the shells, single riveted, originally five-sixteenthsof an inch thick. The two exploded boilers were made twenty-oneyears before the explosion, and worked, as their makersintended, at about thirty pounds per square inch, untilabout twenty months before the explosion, at whichtime additional power was required, and the pressurewas increased to, and limited at, fifty Fig. 38.—Position of the Three Boilers after the Explosion. A third boiler did not explode, but was thrown aboutfifty feet out of its bed. A few minutes before noon, while the engine wasrunning at the usual speed, the steam-gauge indicatingforty-seven pounds pressure, and the water-gauges show-ing the usual amount of water, the middle one exploded; THE RESULTS OE EXPLOSIONS. 137 the shell burst open and was nearly all stripped off. Theremainder of the boiler was thrown high in the air. While this boiler was in the air, No. 1, the left-handboiler, having been forcibly struck by parts of No. 2,also gave way, so that its main portion was projectedhorizontally to the front, arriving at the front wall ofthe building in time to fall under No. 2, as shown inFig. 38. The most probable method of rupture is indi-cated in Fig. 38, as the line A B separates a ring ofplates which was found folded together beneath the pileof debris. If the initial break had been at some pointon the bottom, this b
