A textile mill reference by E. A. Posselt that teaches the calculations used in yarn, warp, filling and cloth manufacture. It covers yarn counts in the cotton, woolen (run and cut), worsted and silk systems, ply and mixed yarns, reed, warp and filling calculations, and the cost of materials for sample fabrics such as cassimere, worsted suiting, beaver overcoating and ingrain carpet. Later sections cover choosing the proper cloth texture for different weaves (twills, satins, ribs, backed cloths, double cloth), analysis of fibres and fabrics with microscope illustrations, cotton spinning tables, speed, belting and power, and a primer on arithmetic for textile work. Advertisements for textile machinery makers appear at the front and back.
