Scientific American, Vol. 33, No. 1 (1875)
A weekly American science and engineering periodical from 1875, published in New York for a general readership of inventors, mechanics and manufacturers, with its pages carrying wood-engraved diagrams of machines and furnaces. Its pictures are precise cutaway and sectional engravings of boilers, furnaces and a pump-like engine, drawn with hatched brick, dense metal shading and labelled lettering, which a designer might take as a model for clean technical line work and mechanical framing.
