economists. IL is certainly true of these
islands whose great source of wealth and /
prosperity, as well as the creator possibili- |
ties of tho future, are to be looked for in !
the cultivation Of the sugar cane, exclusive
of all other industries. 1t is incumbent
then upon the planter to devote bis energies
to such ends, not permitting his faculties
to lie inert, but on the contrary, being ever
wakefnl and vigilant and by remedying
defects or investigating new processes
he will be enabled to proftably compete
with other sugar.growing countries aud

have before his minds eye, the watchword
Eternal vigilance is the price of sugar"
1t is n fact and one TO be deprecated,
that with the more than ordinary intclli-
gence displayed by one planter in his
knowledge Of the growth and cultivation
of canes, there are comparatively few
familiar with the process of manufacture,
or who have devoted much leisure to
study of it's details and minutim, ignorant
Of facts with which they should be con.
yersant, ut times even being at the mercy
of incompetent men whose main desire is
to conduct things their own way, regard
less of the planters interest. Fortunately
their evil ways soon find them out, and
these instances are every day diminishing.
Even now, question is agtating the
minds of planters and mill owners, certainly
mn important one, which, whether adopted
err rejected, illustrates the necessity of ever
being active and determining by constant
systematic experiments, whether he is OBJ
tanning maximum results Mt q minimu out
lay: The subject referred to being, namely,
whether the method hitherto in vogue of
boiling sugars into grades of !, 2, 3, etc,
yielded the planter maximum percentage
of sugar to the gallon at better prices, or
again, tho making of one grade sugars by
constant absorption of moasses into the
vacuum pan from previous strikes to
mingle with pure Juice. Parties who have
tried this latter method, claim to have OBJ
tanned higher prices and best results to
gallon; in the last instance dollars, in the
former loss.
1t would be advisable perhaps for the
plante. who has not already done so, to in
vestigate by practical and conclusive ex-
pertinent the value or uselessness of this
recommended method, in manner easily
adjusted to his satisfaction, since by max
ing his sugars ms per old method. viz, | 2,
3, etc, for say two weeks, tabuating his
number of CHARTERS and yield in pounds to
gallons, and then by the other plan an
equal number of CHARTERS, density as on
the foregoing occasion and all other condi-
tons the same, investigating yield ms be-
fore, and then forwarding to market in one
shipment, basis can be determined upon,
making it obligatory upon the mill manu-
featuring refinery sugars to give either old
or new the preference.
The writer's experience substantial
by communication with parties largely in.
tercsted in sugars condemns the practice
of constant absorption of molasses into
juices to form one grade sugars and be-
loves the methods ut present followed of

We are told that high lining is neces-
sary in the manufacture of one grade
sugars, the representative of one of our
large firms stating that the returns were
largest from one plantation which had been
in the habit of using five pounds. No
other data was given. Therefore if the
planter add five pounds, though the juice
may require more or even less, add five
pounds and you will get higher prices for
your sugar and lots of 1t.
Now this addition and use of lime in the
manufacture of sugar is of great importance
SO that we will enlarge more upon it. We
know that upon the collection of normal
quantity of juice say 500 imperial gallons
in the CHARTERS, q sufficient amount of lime
is added, either in the form Of milk or
bydrate, though best at q density of
about 200 Beaume, both boiling into in.

to which is its efficacy in throwing to the

This addition of lime if not carefully
done detororates the juice, since too large

difficult to clean the juices, not to forge,
