THE CENTRAL MILLS SYSTEM.

apparently working without 5 hitch

e5fv 4 good one both for the planter
ana she manufacturer, II Is certainly

made on these islands. By this ar
raneemeut they not only get two

from IS 70 - per cent. more sugar

besides getting higher polarization
The distribution Of the time also has
some advantages Each planter grinds

from so 70 $40 tons OF sugar in this
length Oi time. They also usually
save enough seed from this grind 10

leaves their men free, 50 that they can
DO the planting and hoeing in the
proper season This method has
worked 80 satisfactory that we find

crop Of about 1000 tons. The others
are well along with their work and

FLUNING THE CANE.
Il has been clearly demonstrated
here that, where fuming the cane IS
practicable. distance does not materi-
ally increase theeOst Of transportation.
The longest distance, so far, is from
OnOmeS about five miles,, and the
cane WIS fiumeG from this place for
50 cents per clarifier. Ii would be diff
ficult 10 reduce this amount, no matter
how near the cane might be.
The arrangement maGe here Is very
simple. The planter cuts the cane
and Laws il near the fiume, and the
mill companv fumes IL for 30 cents
per tou Of sugar. Now il usually
takes about seven tons Of cane TO make
s ton Of sugar, 50 that il would cost
the planter bat cents ton to have
his cane transported 20 the mill. The
cost for putting up the fume was
$1,000. and il i one OF the best in the
district.
TIE MILL
This mill was remodeled about three
years ago st cost OF about $4,000,
and put in what was considered first
class order. The three-roller mill at
this place is especially adapted for
doing good work; the engine is of the
best design and Is gesred up very high,
about forty revolutions OF engine 10
one Of mill; the engine runs at very
high speed, and develops an immense
power. The train Of gears is double or
compound The rollers are 30x60,
ceared with steel piniOns. The re-
turning bar Is six inches in diameter
znd possesses great strength and rigid
lty.
The twO-roll mill i the usual size
found here, SgX60, and Is driven by
Corliss engine. geared foTty-fiye reyo-
lutious TO one OF mill. The gearing Is
single with large spur wheel built or
made in segments. This Is considered
the best wheel for this purpose Both
Of these mills are especially made for
doing the best possible grinding, and
the work done by them cannot be
surpassed
The boiling house has been entirely
rebuilt and Is now considered 10 be
one u the best on the island. It con-
tsiIS all OF the latest Improvements
except the vacuum cleaner. There
are TWO vacuum panS-one five tons,
the other four tons. There are four
CHARTERS, four cleaning pans and four
centrifugal machines; one double
effect u the usual size zone seven, and
one six foo pan, and II works 10 per

There are two pairs of compound boilers

The main object in view when the al
reratiOns were made, was to so arrange
everything about the mill, as to do the
best possible work with the least ex-
peuse a well IS to increase the capa-
city In this they have been success

months work viii fully demonstrate,
A GOOD MONTHS WORK.
The number Of CHARTERS ground in
the month Of April was 1851, and
made 5s5l tons Of sugar. Half the
time II was dry grinding, the other
half with maceratiOn. The average
number CT CHARTERS per week for dry
grinding was SOL. The average num-
Ter for msceratiOn was 35S per week.
The greatest number Of CHARTERS made
III one dav was ~. and the least num-
Der AZ the average was Il CHARTERS
for every working day IN the month.
The largest amount Of sugar made IL
one dGv was so tons; the largest
amount for one week, l5S tons. The
amount % sugar per clarifier cannot
be ascertaiued. as the low grades are
not all dry Vet, but in some Of the
previous months st5 lbs per claTifieT
VS. got with dry grinding. To do this
amount u work il was necessary to

rEn u p. m; and the boiling house
% start ar I a. m, and work TO $50 D.
n This may be considered, under
present circumstance, n working the
mill up 20 its fullest capacity, but by
making a few alterations It Is consid-
cred possible 10 exceed this amount Of
wcrk.
The work Is not only done with dis
patch, but according to the most APP
proved and best practice. The num-
