Journal of the Association of Engineering Societies
A periodical of engineering papers issued in 1881 by the Association of Engineering Societies in New York, written for working engineers and society members. Its pictures are plain technical line drawings: a dam cross-section with pressure lines, a pipe-and-bolt fitting, a graph of earth pressure on pipes, and a contour plan of a site. A designer could take their clean hatching, dimension lines and contour rhythms as a model for precise technical diagrams.
