Saves cost in a few weeks. Will not burn. Numerous Testimonials, and over Nine Thousand References. Some idea may be gathered of the saving effected by our Composition from the fact that in scores of cases extending over a period of twenty years, where concerns have been worked by four boilers, after being coated with our Composition they have been enabled to work the concern with three boilers, and allow one to be at rest. Will Last Twenty Years. Does not Shrink.
