Home-farm power and lighting, a book of helpful instruction on the installation
A 1920 instructional manual on farm electric plants and lighting, issued in Cincinnati by the American Automobile Digest for farmers installing their own generating sets. Illustrations run from hand-drawn dynamo and magnetic-field diagrams with arrows and polarity marks to wiring schematics of switchboards, batteries and lamp circuits, plus halftone cutaways of engines — useful as line-diagram stock and technical arrow-and-label vocabulary.
