A merchant's handbook on silk production, published by the Macclesfield silk merchants H. T. Gaddum & Company. It covers the silkworm life cycle, mulberry cultivation, cocoon handling, raw silk reeling (native, European, steam filature, Minorikawa and automatic reeling) and modern developments in sericulture. A country-by-country survey runs from China and India through the Near East, Europe, Africa and the Americas to Japan. Later chapters cover waste silk and by-products, estimated raw silk production figures for 1938 and 1977, and facts on quality grading and testing. Illustrations include a reeling engraving, a reeling diagram, maps and a yield graph, and there is an index.
