Take 100 lbs. of white sugar, and mix with it 3 gallons of water, in a copper or iron boiler of 50 gallons capacity. It is necessary to have the boiler this size, as in manufac- turing 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 boiling until it gets as black as tar when dropped on a cold stone. Then add slowly 6{ gallons of boiling water at firsts only a little at a time^ and increas- ing the quantity gradually — constantly stirring as the whole is dissolved. Pass it through a flannel. Take 3 ounces of sulphuric acid (smoking) and put it m a one-gallon glass jar ; add, in very small portions, 1 ounce of the finest powdered indigo, being very careful to stir the ingredients constantly during the process 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 con- tinue stirring it as long as a froth rises from the mixture. After having done this, let it stand for 24 hours, then de- cant, filter, mix 1^ pint of alcohol with it, and bottle for use. 89. Color, Blue.

By mixing the tincture of saffron and the tincture of in- digo together in different proportions, you can obtain any shade of green you desire. For a light-green, increase the saffron ; for a dark-green increase the indigo. 6*
