The following suggestions may
prove of use:

humps of lime, etc., in the mixture
will clog pump or nozzles. Therefore,
thoroughly clean all vessels to begin
with. Strain all water and copper So

be quickly dissolved in water by heat
ing in a brass kettle TO the boiling
point or by pouring boiling water
over il. The most convenient way
that we have found. however, is 10
dissolve il la cold water by putting it
in coarse sack and suspending this
in the top Of tub or barrel Of water
As fast as the heavy solution forms. it
settles 10 the bottom and fresh water
rises. By using a gallon of water for
each pound Of blue yitriol, it will dis
solve in few hours in this way.

find il most convenient todissolye con
siderable blue vitriol AT a time in the
above manner, and TO keep ii on hand
in covered barrel. We put in a
pound Of yitriol for each gallon Of wa
ter. and a we wish il from time to
time, we simply stir il up and dip out
as many gallons Of the solution as we
wish to Use pounds Of blue yitrol.
4. Other C0areaieat Heih0dS. To
avoid the trouble Of weighing, the
blue vitriol may be measured out Give
pounds equals two quarts, and the
lime added by test. This test consists
OF the pouring Of few drops Of solu-
tion Of ferro-cyanide Of potassium n
ounce in four oances Of water into
the mixture. II there is not enough
lime in the mixture, this solution will
at once turn brick-red; but if enough
lime has been added, there will be
no change Of color.
