A short encyclopedia entry defining spinning as two distinct manufacturing operations: spinning of animal and vegetable fibres into thread, and spinning of soft metals. It describes fibre spinning as forming a continuous uniform thread from aligned fibres by twisting. It contrasts the spindle, distaff and spinning-wheel, which produce a single thread, with cotton spinning machinery that can produce nearly two thousand threads at once. It refers readers to other entries on cotton, linen, silk, and woollen and worsted manufacture.
