beyond measure the importance of matters that
combine with the saccharine 10 form the juice of
the cane. we. in retaliation, have, later, too
much neglected the role some OF these substances
play during the process Of manufacture. The
ruling scientific idea now in regard 10 cane juice,
which considers it sugar-water nearly pure, does
not appear to us exactly true, and, IN effect,
ought not 70 be hereafter accepted without restric-
ton. Juice, in It's natural state and under spe-
cial circumstances, which L shall soon make
known. presents certain conditions which it is
necessary to thoroughly appreciate if you would
understand the different results which are often
obtained under the influence of the same pro-
cesses Of manufacture. That composition so sim
pie attributed 70 Juice Is then not only in oppOsi-
ton to the daily practice at the mills, it is still
at issue (cOntrQire) with prolonged and attentive
studies of the cane at different stages Of Its de-
vel0pment. From that arise difficulties and tram
mels in It's manufacture which people have benev-
olently attributed to the inexperience of the
planter and to his pretended desire not 10 wander
from the beaten path traced out before him.
Chance, that providence of ali new industries,
has since the commencement of the sugar busi-
ness in the colonies, revealed the principal in
dicatiOns that have answered in evaporating the
juice, in order to furnish a sufficient quantity
and good quality of sugar. So, whatever may
be the apparatus employed, we shall never digress
from the old method, which will remain a necess-
ity So long as the present legislation will not
permit us 10 use animal-black 10 make refined
sugar al the first operation (premier Jet)
In the present state OF our market and all
other opposing eventualitics which weigh so
heavily upon the production of the colony. so
complete a reform is not realizable. The colon

turers, the planters have not to calculate upon

grades (nuanoes) sought in the colonial markets,
grades which are far from answering 10 the sac

such a situation we must then wait 10 verify the
great difference in the results furnished by e-
aiming the second sirops coming from the mill,
according to the grades, more or less In request,
which they make for, as / shall show further
along, the first qualities obtained by our present
process can be realized only at a sacrifice of sugar
much greater than is generally supposed. This
loss Will be still more manifest as the juice en-
ployed will be found in one of the conditions TO
which l shall allude at the end of this work.
L by examining the degree of press
ure which can be obtained by the means now
employed at Mauritius, that is to say to deter
mine the results obtained at the mill, the differ
ent species of cane and the influence produced
upon the particular (intime) composition of the
juice on account of foreign substances derived,
more or less, from the means employed 10 pro-
duce this pressure. (All of which means, in
plain English, that the juice is more or less effect
ed by the degree Of pressure used in grinding
and varies the final result.)
Afterwards, l shall expose the principal physi-
cal characters which distinguish the juice freshly
expressed, and shall indicate the particularities,
furnished by microscopic examinations, that APP
pear to me worthy to arrest hereafter the atten-
ton Of the planters. Secondly. l shall examine
the chemical qualities of the juice and dwell par
ticularly upon certain substances of which the
nature and mode of action have not up to the
present time been sufficiently determined, and,
finally, in the third part shall endeavor to point
out precisely the alterations undergone by this
liquid during evaporation through the processes :
now put in use in this colony.
To be continued.
