There are four causes which are known to produce boiler explosions, viz.--1st, original weakness; 2d, weakness caused by gradual deterioration; 3d, working the boiler at a pressure greater than it is intended to sustain; and 4th, the sudden production of steam in quantities so great that it cannot escape by the safety-valve or be worked off by the engine, and consequently producing a pressure greater than the boiler can bear.
