u 'he use OF bi-sulPhite is adopted, the new

S the action OF rasps will be necessary until a
g profound study of the effects wrought on the

gone INTO. 1t has seemed 10 me that the
saccharIne liquids obtained by maceration OF
l,vlgation could be operated on more easily,
than the natural juices proceeding directly
from rasPings and dressings do not ven
ture to assert that the present presses will
De preserved in cases where the rasps may
be; everything about them is calculated for
rapid operations. Now the pulps once rem
dered inalterable, slow presses, operating on
large masses, ecOnomyzing manual labor, do
ing away with bags and hurdles, may offer
I certain advantages and obtain a decided
preference. The defecation operated by
means of the bi-sulphite, being the same in
process as by lime, the clarfers (chan-
dIeres devoted to it, and whose arrange
ment is so well regulated, will always be in
dispensible. The filters of Taylor, or some
analogous ones will come into play in the
new system, as well as in the old, except in
cases where it is preferred to operate by de-
position, which is practicable.
The apparatus of evaporation over an open
hre may answer at the commencement Of
the concentration Of the juice but at the
close recourse must be bad either to rapid
evaporation in pans heated by steam, or to a
slow crystallization effected in hot rooms
| (etures). l am quite sure that this opera
ton may be carried on in utensils of plate
iron, ,of timed copper, oi timed iron, and very
probably IN vessels of wood and of cemented
bricks. The use Of animal black NAV be
dispensed with, reduced or persevered in,
Just as one proposes to make raw or refined
sugars. As for the molasses and their salts.
there will always be way TO use them, ex-
cept such portion as may be needed to |
sprinkle on the pulps to season them, and
make them food for cattle Indeed, agricul-
ture in France makes great use of sea salt
1t might with much more reason make use of
the basic salts of Potash, and when il hap
pens that in a country where nothing is lost,
like the Departments of the North, ,hev have
such salts in the molasses; when to cause
the latter to be eaten, is all that is wanted
10 have these salts serve to fatten cattle, pass |
into manure. and return into the earth, that |
department will avoid large expectation of
products of which it robs its own soil. Who
will venture to affirm that it will not be la
mented some day! The sugar-producfng
countries can export as much of that as they |
please, the air and water suffice TO give them
elements, but the salts of molasses once ex-
ported are not so easily recovered To ex-
haust the pulps Of all the crystallizable sugar
they will yield, to restore them by way o!
seasoning part Ofthe molasscs and its salts.
such would be in my estimation, the most
logical method OF proceeding, having re-
gard to the general economy of the soil of
the country. |;
But In order to make these remote provis-
ions acceptable to private interest, it is
necessary that they find in them some pres
ent advantage. 1t is requisite then III this
particular case, that there be greater profit
in extracting all the sugar from the pulps
than in selling the molasses. Operations on L
a large scale can alone show if this advan-
tage exist as believe it does The preced- i
ing indications must make it easy for every |,
person interested in the various manufac- Ii
turing operations to which they relate, the S
exact appreciation of the bearing ofthe facts G

given a crystalliZed mass Of a straw color d
which has also been analyzed by the process tt
