A 1906 International Correspondence Schools textbook (Reference Library vol. 89) that bundles five instruction papers for textile mill students: Yarns, Cloth Rooms, Mill Engineering, Reeling and Baling, and Winding. The Yarns part, which opens the volume, classifies cotton, linen, hemp, jute, ramie, woolen, worsted, hair, silk, mineral and novelty yarns by material, preparation, count, put-up form, and use. The remaining parts cover cloth-room machinery and inspection, mill construction and power plants, cotton-mill planning with production tables, yarn reeling and baling, and winding machines. Each section ends with examination questions and illustrated line drawings of machinery and yarn forms.
