The Methods of Decay are as various as theforms and locations of the parts subject to Colburn* has said As a malady, corrosion corres-ponds in its comparative frequency and fatality, to thatgreat destroyer of human life, consumption/ and it hasas innumerable phases and periods of action. The twomost common methods of decay are the general, andhere and there localized, corrosion, that goes on in allboilers, and, in fact, on all iron exposed to air and car-bonic acid presence of moisture; and the concentratedand localized oxidation that is often seen along the lineof a seam, at the edge of the lap, where the continualchanging of form of the boiler is as constantly producingan alternate flexing and reflex motion of the sheet whichthrows off the oxide as fast as formed along that line,and exposes fresh, clean metal to the corroding influence.
