Journal of the Association of Engineering Societies
A periodical of engineering papers issued in 1881 by the Association of Engineering Societies in New York for its professional membership, with the Smithsonian Libraries holding this copy. Its pictures are measured technical drawings: a cross-section of a boiler-like vessel with dimensioned valves, a furnace or chamber section with arched brickwork, a plan of a railway crossing with track layouts and station labels, and an elevation of stacked tanks or cylinders with brick arches. A designer could take from them the precise line weights, hatching patterns and dimension call-outs typical of nineteenth-century engineering drawing.
