Scientific American, Vol. 80, No. 11 (1899)
Scientific American, volume 80, number 11, is a weekly American periodical of 1899 that reported on inventions, engineering and industry for a general technical readership. Its pictures are wood-engraved and halftone views of machinery, with a locomotive, a boiler water-heater with cutaway detail, an iron-smelting mill interior and a hand-operated paper punch. A designer could take from them the clear, labelled line drawing style used to explain mechanical parts.
