Scientific American, Vol. 24, No. 11 (1871)
A weekly American magazine of science and invention, published in New York in 1871 for engineers, mechanics and general readers interested in new machines. Its pages carry technical engravings of steam traction engines, road rollers, a rail-clamping tool and mechanical details, with the reader's eye guided by labelled diagrams and captions. The side-elevation and front-view engravings of the steam engine show clean hatching, crisp outlines and clear part labels, useful for designers wanting an authentic nineteenth-century mechanical drawing style.
