Developed Weakness, usually a consequenceof progressing decay by corrosion, is the most commonof all causes of the explosion of steam-boilers. Aboiler, designed and constructed of the best possible pro-portions and of the best of materials, having at thestart a real factor of safety of six, may be assumed tobe as safe against this kind of accident as possible ; but,with the beginning of its life, decay also begins, and theoriginal margin of safety is continually lessened by anever ceasing decay. The result is an early reductionof this margin to that represented by the differencebetween the working-pressure and that fixed as a max-imum by the inspectors tests. Should this differencebe sufficient to insure against accident, resulting fromfurther depreciation, in the interval between inspectorsor other tests, e
