A treatise on architecture and building construction
A multi-volume correspondence-course textbook on architecture and building construction, issued by the International Correspondence Schools in Scranton in 1899 for tradesmen and draftsmen studying by mail. Line engravings show joinery, masonry bonds, and wall sections in axonometric and cutaway view, with keyed letters, hatched cuts, and material textures — usable as diagram vocabulary, pattern fills, and technical line detail.
