In securing this elimination Of the
Juice and preventing re-acidulatiou
lies one OF the great fundamental
means Of success in the manufacture OF
sugar from any variety Of cane, being
difficult Of attainment, (more particu-
larly in the African cane.) owing to
the disposition in the canes not to ma:
ture at the same time.
Having secured the cane at ito best
stage, the next question is the best
mode or manufacturing. An iron
mill. with at least three rollers, should
be used, ss the wooden mills (Which
answered we'll for our primitive ex-
periments) lose one half Of their juice
The cane should be stripped, topped.
and, for very nice experiments, should
be cut in the middle, the butts press
cd and evaporated by themselves for
sugar, and the tops for strip In my
in 1851 | used the whole
stalk with complete success.
OF the most vital importance is the
mode of DELEGATION and evaporation
To boil the juice in the ordinary ket-
ties or pans is 70 waste both your time
and your crop, as has bsen fully de
monstrated by the thousands OF exper-
iments heretofore made.
Dedication aud evaporation must
be combined in one action; that is,
during evaporation there must be 81
defecation- The albuminous
matter will not coagulate except up-l
on the application OF an active heat,
and as this matter and other impuri-l
ties rising in the scum cannot rest up
on boiling surface without being
again plunged BY the Currents intol
the Juice, and finally, 90 incorporated
withe strip as TO prevent granulation,
Il is clear that the evaporator must
afiord mcans Of retiring this scum
from the boiling surface as rapidly as|
Il arises. Hence there must be cool
surface within the pan outside theI
line OF ebullition, where it may rest.
This cooling surface is indispensable,
and no one has succeeded in makingI
sorgho sugsr who did not use it. II
therefore made . pan with the sides
over the surface several
inches.
In my first experiments used lime
ID DELEGATION, but finding that . sim
Die active heat was the best deiecator,
abandoned It To secure the best
effect in defeating by heat, and also
the most rapid evaporation possible,
which is another great requisite to
success, the juice should be boiled in
bodies. In doing % found
great danger Of burning, and, there
fore, introduced running stream Of
Juice into my pan; but Is the scum

would pass down the whole length OF
L, and mingle with the strip as il
out into my coolers, | con
structed lodges starting ont from each
side alternately, and reaching nearly
across the pan, thus giving me q zig
sap current from one end to the other.
These lodges held the scum ct the
cool sides until removed BY . skim
mer. They also accomplished another
important and very unexpected result,
which | will endeavor to explain:
Different degrees Of heat canse dit.

surface. At the front end Of M pan

being hotter, another kind, and 80 on,
until about half way down my pan
