Journal of the Association of Engineering Societies
This is a periodical of engineering society proceedings issued by the Association of Engineering Societies of the United States, published in New York in 1881 for practising engineers and members. Its pictures are technical drawings: a plan of experimental contact beds with an open septic tank, a cross-hatched elevation of a structure with braced trusses, a stepped masonry cross-section labelled with filling and courses, and a circular sewage tank plan with arched roof and screen chamber details. A designer might take from them the precise line-drawn diagram style, lettered callouts, and hatched textures.
