now in use on our plantations, about l4O gallons
of molasses are obtained 70 every 5000 lbs. of
sugar; but by tins improved process the quantity
Of molasses is reduced to about 80 gallons to the
same product Of sugar. If this prove on further
trial t. be so, it forms a very strong
dation in favor Of the general adoption Of this
new process OF boiling.
Ii is generally supposed that lime is absolutely
necessary in the manufacture Of sugar, to cause
i; to gr4nulate, and it is universally used in the
old method. Mr.. Coaks informs us that in the
manufacture Of sugar by this improved pan,
lime Is not necessary, and that sugar Is made
without it. And when lime is put in, only the
most triding quantities have been used. more
from custom and from 4 suppoSition that il IS
ueeded to perfect the grain, than that it is really
required.
We have before US a sample of sugar made by
this process. taken from the cooler far and a
hay hours after the cane was standing in the
field. 1t is a fine grain. Of a clear white color,
comparing favorably with the No. l of cur best
plantations.
Our readers viii obtain from the data given,
sufficient insight into the working of this new
process TO show that it is a decided Improvement.
when operated on a small scale. The pan refer

lbs. per hour or 1000 lbs. per day. This is too
small for our plantations, and the question
now Is, can larger pans be used with equal sue,
cess? Messrs. c. and d. inform us that a fE-
teen feet pan, which they have superintended in
the manufacture Of sorghum syrup, worked even
better than this. The only limit in the size Of
these pans that Will be found practicable, will
probably be the surface to which Il uniform heat
can be carried, which VIII probably be not over
24 feet in length. Mr.. James Louzada Of Wal
kapu, is having two large pans constructed, 8 by
p feet in size, TO be superintcnded by Messrs.
Geo. II. IngJIs and H.. Davis. These. it is
thought, viii turn out each about two tons Of
sugar every ten hours, as each has four times
the surface and capacity of the one on Mir.
Woods plantation. But the working Of large
pans, and the quantity Of sugar they Will pro-
duce are matters of experiment, which, like
many other of the minuti;e Of sugar manullc-
ture, can be decided only after various trials.
The chief recommendation Of these improved
evaporators, 50 far as we can judge at present,
are
Ist.-The reduced cost, enabling persons to
engage III the manufacture of sugar with Il com

2d.-The decreased amount of molasses pro-
duced and greater yield of sugar caused by the
rapid evaporation, saving to the planter a larger
percentage of his labor, and enhancing the value
Of his estate.
3d.-Great economy in fuel, labor and time,
in our islands are important items.

actured without lime or even with a less guam
-ity than now, it must increase the value of the
sugar.
1t is easy to forosOO that, If THO Improvement
; what our best and most reliable planters now
suppose it to be, its Introduction may produce
revolution in the manufacture Of sugar, which
will be worth millions to the islands. Hereto
it has required large capital to start plan
ations-irom twenty to fifty thousand dollars
,eing the usual outlay, though some of our older
limitations have absorbed each over one atq-
MovSaAd dollars. Now if the manufacture
+ sugar can be 50 simplifed, as it promises to be
y this system, any one with ordinary business
ac., who chooses to undertake its manufacture,
an acquire the knowledge OF a sugar boiler
nd conduct his own operations with a compare
lively small outlay Of capital. There are hun
reds Of localities, even on Oahu, where from
en- to one hundred acres Of good cane land are
ound in one spot, that can be brought under
and Will be found TO be pro-
uctive land for cane. And if a capital Of a
wv thousand dollars, with the improvements
ow in process, can supply the means of turning
he juice into SUGAR of marketable quality, it
ill not be many years before we shall have a
of mills where one now is found and
here there are twenty now in the group, we
nall have two hundred.
On this subject Of sugar plantations we have
facts to present, showing that our islands
re peculiarly adapted for sugar manufacture on
largely-increased scale, but shall defer them to
mother number.
We may remark, however, that the gentle
ZEN who have at their own risk introduced the
wv evaporator which we have described, deserve
lie thanks of our planters and of the public,
al WE trust that their services viii be sought
