Marine engineering
Marine Engineering is an 1897 periodical published in New York by the Marine Publishing Company, aimed at shipbuilders and marine engineers and held by the Smithsonian Libraries. Its pictures are precise mechanical line drawings in hatched section, showing a steam safety stop, boiler stay bolts, a stepped flange joint and a hydraulic distributing valve, so a designer could borrow their clean technical diagram style and cross-hatching for industrial or engineering graphics.
