Volume 65 of the I.C.S. Reference Library, a 1905 textbook compiled from International Correspondence Schools instruction papers on the woollen trade. It covers wool and other fibres, their properties, and wool sources and sorting. It then follows processing through washing, drying, burring and carbonizing, opening and mixing, oils and oiling, woollen carding and card clothing, and woollen mule spinning. The text is illustrated with many machine diagrams and includes an appendix of chemical terms, but it has no weaving drafts.
