First monthly part (May 1900) of Charles G. Petzold's textile-school text book on the construction of weaves, intended for designers, overseers, loom fixers and webdrawers. It opens with a preface, an illustrated abstract of contents, and an introduction on the three branches of the textile industry. It then covers plain weave, warp and filling rep, mixed or seedy rep, and twills and diagonals, including a method of laying out twills on a line plan and many numbered drawdowns from 3 to 16 harnesses. Portrait and pictorial plates (L. J. Knowles, Columbus Sighting America) and advertisements for loom makers and harness makers are included.
