Scientific American, Vol. 84, No. 9 (March 1901)
An issue of Scientific American, the weekly technical and trade paper published by Munn & Co. in New York in March 1901, written for engineers, manufacturers, inventors and mechanically minded general readers. The plates are wood-engraved and line-block depictions of engines, dynamos, punch presses and shop machinery, often paired with sectional diagrams, plus small advertising cuts of bound volumes and treadle equipment, offering designers crisp black-line machine forms, hatched shading and cross-sections.
