deep a shade.
Very light shades can also be done on the padding machine. The
dye-stuffs of Group (2), which have been previously enumerated, do not
stain the wool at all or only very slightly and are therefore the most
suitable. Less bright effects can be produced by simply dyeing the
goods in one bath. The wool is first dyed at the boil with the wool
dye-stuff in a neutral bath, the steam is then shut off and the cotton
dyed by adding the cotton dye-stuff to the bath and dyeing without
again heating. By passing the goods through cold water to which some
sulphuric or acetic acid is added the brightness of most effects is
greatly increased.
_Gold and Green_.--First bath, 1 lb. Cyanole extra, 7-1/4 oz. Acid
Green, 1-1/2 oz. Orange G G, and 10 lb. bisulphate of soda; work at

We may here note that in all the above recipes the second bath (for
dyeing the cotton) should be used cold or at a lukewarm heat, and as
strong as possible. It is not completely exhausted of colour, only
about one-half going on the fibre. If kept as a standing bath this
feature should be borne in mind and less dye-stuff used in the dyeing
of the second and following lots of
