acidity is the consequence; which acidity
increases with the distance of the tank
from the mill. [ have recently been able
TO obviate this diff Guilty also, by commence
ing my treatment Of the juice as it falls
from The crushing cane, in The mill. This,
too. IS done without interfering with the
work, or the work people. | may add,
that the cano-juice flows out Of the mill
unio%tefruptelIy, AM is passed on into the
tank, wa re gaIvaoic action is repeated, to
complete the initiative in the mill, and
separate the d)tting Impurities, by filter
ing the Juice five times before it leaves
the tank c'ari d. There is no handling
Of the ace all this time, if we except tbs
Summing OF it.
j is thus that fermentation ig checked,
aud may be perfectly prevented, Of mo-

empty OF sacoharine matter; thus, we
stop up all means of pgresS, SO TO speak,
that our loss Of sugar may be positively
insignificant. Even all drainage, as from
centrifugAIs, is returned to the pans on
copperwaI!, - to come on with the
next charge of sugar.
My Jamaica friends challenged me,
with: :" If you deprive US Of the sugar

"~Scummiugs of the pans, as they grow
-" rich in sugar, how are we to realise our
g superior rum, which commands the

reply waS,-As sugar is not ubiquitous.

which pays best.
