. Enter wool at 160 deg. F., give four turns, raise
temperature slowly to a boil, and turn to shade, lift and wash.

_Scarlet_.--Prepare a dye-bath with 2 lb. Azo cochineal, 10 lb.
Glauber's salt, 4 lb. sulphuric acid. Work at the boil until the full
shade is obtained, then lift, wash and dry.

_Terra Cotta Red_.--The dye-bath is made from 2-1/2 lb. Fast Acid
Magenta B, 2-1/2 lb. Fast Yellow F Y, 10 lb. Glauber's salt, 2 lb.
sulphuric acid. Work at the boil to shade.

_Fast Scarlet_.--Prepare a dye-bath with 3 lb. Glauber's salt,
1-1/4 lb. sulphuric acid, 2-1/2 lb. Brilliant Scarlet 4 R. Work at the
boil for one and a half hours.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet 2 R J, 10 lb.
Glauber's salt and 2 lb. sulphuric acid. The goods may be entered at
about 150 deg. F., and the temperature raised at the boil and maintained
at that heat for one hour, then the goods are lifted, rinsed and
dried.

The method given in the above recipes is that usually followed (p. 106)
with the acid colours. When closely woven or thick goods are being
dyed, where it is desired that the colour should penetrate well into
the substance of the goods, the following modification of working may
be adopted:--

The dye-bath is made up with the dye-stuff and Glauber's salt only,
and the goods are worked in this at the boil until they are thoroughly
impregnated with the dye-stuff liquor, then the acid is added in small
quantities at a time, and the dyeing is continued for one hour to fix
the colouring matter on the wool fibre. The goods may then be lifted
out, washed and dried.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet F R, 10 lb. Glauber's
salt and 2 lb. sulphuric acid. In place of scarlet F R, the F 2 R or
F 3 R brands may be used, the latter giving the reddest shades.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet O O, 10 lb. Glauber's
salt and 2 lb. sulphuric acid. Scarlet O dyes a yellower shade of
scarlet, while scarlets O O and O O O dye slightly redder shades.

_Scarlet_.--The dye-bath is made with 3 lb. Brilliant Ponceau 2 R,
10 lb. Glauber's salt and 10 lb. bisulphate of soda. This gives a
brilliant shade of scarlet. Brilliant Ponceau G, used in the same way,
gives a much yellower tone of scarlet, the R gives a slightly yellower
tone, while the 3 and 4 R brands dye redder shades.

_Bluish Red_.--The dye-bath is made with 2 lb. Brilliant Croceine B,
10 lb. Glauber's salt, and 10 lb. bisulphate of soda. Bril
