1. Coloring.
Take 100 lbs. of white sugar, and mix with it three
gallons of water, in a copper or iron boiler of fifty Gal
lons capacity. It is necessary to have the boiler this
size, as in manufacturing coloring the liquid is apt
to run over when made in a smaller vessel. Put the
boiler on a smart fire, and stir the sugar constantly, so
as to prevent its burning on the bottom. Keep it boil
ing until it gets as black as tar when dropped on a
cold stone. Then add slowly six and one-quarter gal
lons of boiling water—ai" Jrs/, only a liiile at a time,
and increasing the quantity gradually—constantly stir
ring as the whole is dissolved. Pass it through a flan
nel.

Take 3 ounces of sulphuric acid (smoking) and put
it in a one-gallon glass jar; add, in very small portions,

of mixing them. Let the jar stand in a warm place
for several days, and then add, very slowly,3 quarts of
water; after which add, in small quantities,^ lb. of
chalk powder, and continue stirring it aslong as a froth
rises from the mixture. After having done this, let it
stand for 24 hours, then decant, filter, mix pint of
alcohol with it, and bottle for use.
