The dye materials imported from foreign countries are principally cochineal, fustic, gum arabic, gum senegal, gum animi, gum copal, gum tragacanth, indigo, lac dye, shellac, logwood, madder, smalts, valonia, yellow berries, and zaffre. The tools shown in the engravings explain themselves, and, as has been already said, principally consist of the various coppers and vats, the syphons or tubes by which liquor will flow from one vessel to another, and the puncheons, for stirring and thoroughly immersing the articles in the dye stuff.
