Part II of a series by Charles E. Pellew on artificial (coal tar) dyestuffs, written for dyers and amateur craftworkers. It explains how to identify a dye by trade name, shade letter and manufacturer, and advises buying from the large German makers' agents instead of retail repackagers. It then lays out a six-class classification of coal tar dyes and begins with Class I, Direct Cotton (salt) dyes, covering their uses, dyeing directions for cotton, mercerized cotton, linen, wool and silk, fastness, a table of selected lightfast colors by manufacturer, and after-treatments.
