Scientific American, Vol. 92, No. 11 (March 1905)
An issue of the weekly Scientific American, published by Munn & Co. in New York in March 1905 for engineers, inventors, and general technical readers. Coarse-screen halftone photographs show tunnel headings with water bursting through rock, timber staging bolted to cliffs, and a man hanging from a multi-wing glider beside a launching trestle, plus line diagrams of patented machinery useful for grainy industrial texture and early aviation silhouettes.
