ted with proper care, _i.e._, keeping the
baths more alkaline and lowering the temperature. The goods are dyed
with the addition for the two coloured effects previously mentioned,
then they are well rinsed, and afterwards the silk is dyed with the
suitable acid dye-stuffs, with addition of sulphuric acid at a
temperature of about 150 deg. F. Care should be taken not to use too much
acid, and to keep the temperature of the bath sufficiently low, as
otherwise the acid may cause some of the dye-stuff to go off the cotton
and tint the silk. It is best to work at a temperature of about 150 deg. F.,
with addition of about 3 oz. concentrated sulphuric acid per 10 gallons
dye-liquor.

For shading the silk all acid dye-stuffs can be used which have been
mentioned in the foregoing tables.

If in shot effects the cotton is to be dyed bright and full shades, this
is best achieved by dyeing with direct colours first, and then topping
with basic colours as follows:--

Bottom the cotton first with the suitable direct colours, then dye the
silk and then treat the pieces for about two hours in a cold tannin bath
(about 8 oz. tannin per 10 gallons of water), then rinse once and pass
through a tartar emetic bath (about 3 oz. per 10 gallons), rinse
thoroughly and dye the cotton to shade with basic colours in a cold bath
to which some acetic acid has been added.

Should the silk become a little dull after this process, this may be
remedied by a slight soaping. After dyeing rinse well and raise with
acetic acid.

=Shot Effects with Black Cotton Warp.=--Effects much in favour are
designs composed of black cotton and light or coloured silk. The most
suitable black dye for this purpose is Diamine black B H, diazotised and
developed.

Dye in as concentrated a bath as possible at about 160 deg. F. with about 6
lb. Diamine black B H, 1 lb. Diamine sky blue, pat., per 100 lb. of dry
goods, 1/2 lb. Diamine orange D C, pat., with an addition of 6-1/2 oz.
soap, 4 to 5 dr. soda per 10 gallons liquor, 16 oz. Glauber's salt.
After dyeing rinse well in a bath containing 6 dr. soda and 3 oz. soap
per 10 gallons water, diazotised in a fresh bath with 4 lb. nitrite of
soda and 12 lb. hydrochloric acid (per 100 lb. of dry goods), rinse
thoroughly and develop with 3 to 16 oz. phenylene diamine (93 per
cent.), with addition of 1 to 2 lb. soda. These two operations should
follow each other as quickly as possible, also care has to be taken that
the diazot
