A 1906 textbook of arithmetic and formulas for the textile trades, written by the head of textile industries at the Belfast Municipal Technical Institute. It covers yarn counting systems (cotton, worsted, woollen, linen lea, silk, jute), resultant and average counts, twist yarns, blending and yarn costing, reed and heald sett systems, warp and weft quantities, and the weight and cost of woven fabrics. Later chapters treat fabric analysis and reproduction, conditioning and moisture allowances, and the theory of fabric construction (thread diameters, balance of structure, angle of curvature, compression). Worked examples and exercises with answers close each chapter, and a few threading and draft diagrams illustrate the heald calculations.
