the sulphate of iron, dissolve it, add the
acid, and shake the whole briskly. Lastly, add the indigo-paste, mix well,
and filter again through paper. Keep the ink in well-corked bottles.

COLORING METALS.

Metals may be rapidly colored by covering their surfaces with a thin layer
of sulphuric acid. According to the thickness of the layer and the
durability of its action, there may be obtained tints of gold, copper,
carmine, chestnut-brown, clear and aniline blue and reddish-white. These
tints are all brilliant, and if care be taken to scour the metallic
objects before treating them with the acid, the color will suffer nothing
from the polishing.

FOR CHEAPLY GILDING BRONZES, ETC.

A mixture for cheaply gilding bronzes, gas-fittings, etc.:--Two and
one-half pounds cyanide of potash, five ounces carbonate of potash and two
ounces cyanate of potass, the whole diluted in five pints of water,
containing in solution one-fourth ounce chloride of gold. The mixture must
be used at boiling heat, and, after it has been applied, the gilt surface
must be varnished over.

HOW TO CLEAN A CHAMOIS SKIN.

When a chamois skin gets into a dirty condition, rub plenty of soft soap
into it, and allow it to soak for a couple of hours in a weak solution of
soda and water. Then rub it until it appears quite clean. Now take a weak
solution of warm water, soda and yellow soap, and rinse the leather in
this liquor, afterward wringing it in a rough towel, and drying it as
quickly as possible. Do not use water alone, as that would harden the
leather and make it useless. When dry brush it well and pull it about; the
result will be that the leather will become almost as soft as fine silk,
and will be, to all intents and purposes, far superior to most new
leathers.

HINTS ON DRESSING THE STORE WINDOWS.

In dressing store windows avoid as far as possible placing cards or note
sheets flat; endeavor in some manner to have them erect, leaning against a
box or placed upon a small easel. Neither crowd your window nor place
things in exact rows. Give each article plenty of space in your window;
then you do not need so much to fill up, and on the following week put in
the pieces you might have displayed the previous week had you crowded your
window.
