Scientific American, Vol. 24, No. 26 (1871)
A weekly American science and mechanics periodical from 1871, printed in New York for engineers, inventors and tradesmen. Its pages carry precise wood-engraved diagrams of machines and apparatus, including a well-boring rig, a multi-auger drill, a spoked wheel hub, and a feed cutter. The engravings are crisp, labelled, and built from clean outlines and hatched shading, a useful model for technical line drawing.
