To dye wool GREEN.

The shades of this colour are very numerous, as yellow green, pale green, bright green, grass green, laurel green, olive green, sea green, parrot green, cabbage green, duck's-wing green, &c.

The goods must first have a blue ground from the woad vat, light or full according to the pattern, they are afterwards to be prepared with alum and tartar, weak or strong according to the lightness or fulness of the pattern, and are afterwards dyed in weld liquor. Many of the shades of green are more readily done by dyeing the wool first yellow with old fustic, with a preparation of alum and tartar, and using the chemic blue vat made with sulphuric acid and indigo.
