ROUGHSTUFF—HOW MADE, APPLIED, AND RUBBED.
Webster defines "rough" as "having inequalities, small ridges, or points on the surface," and "stuff" as "refuse or worthless matter." But, combining the two words into one—roughstuff—the painter construes the term to mean something different from the construction put upon it by the eminent lexicographer when he cleaved it evenly in twain.
Without the coarse mineral pigments known as "fillers," white lead, and the liquid mediums used to properly unite and weld them together and denominated roughstuff when ready for use, the painter, in his effort to make satisfactorily level and smooth surfaces, would be in almost as sorry a plight as the mariner bereft of his compass. For, mark you, gentle confrères! roughstuff is essential to carriage body surface elegancies and mirror-like effects.
