DYEING
224. Dyes. One of the most important and lucrative industrial
processes of the world to-day is that of staining and dyeing. Whether
we consider the innumerable shades of leather used in shoes and
harnesses and upholstery; the multitude of colors in the paper which
covers our walls and reflects light ranging from the somber to the
gay, and from the delicate to the gorgeous; the artificial scenery
which adorns the stage and by its imitation of trees and flowers and
sky translates us to the Forest of Arden; or whether we consider the
uncounted varieties of color in dress materials, in carpets, and in
hangings, we are dealing with substances which owe their beauty to
dyes and dyestuffs.
