drance This original contrvance was got.

The 5000 trolleys In use are made of cast
iron with a steel hook and with the rope
sings are returned to the point for bundling
the cane by pack mules and wagons. The
purpose Of not unloading direct to the cars
is to allow the removal of the trolley and
sings from the load, otherwise a part of the
mechanical attachment might get among
the cane and thus enter the rollers of the
mill and cause damage The wire rope used
is onehalf inch thick and known as the
Patent Wire Locked" and presents sur.
face as smooth as a steel bar. The wood
braces that carry the wire are 6x6 timbers
set apart distance varying from 700 to 800
feet. At each brace the trolley and sling
loaded with cane passes over small sheave
set on journal which relieves the sudden
jar Of the load in passing over, and at the
same time forces the load ahead to the next
brace, and so on to the point of dumping
The braces that carry the wire rope are sim
ply made, portable. and are held together
by their own ground weight and simple
iron devise at each end OF the crossbrace,
which can be raised or lowered to any desir-
ed height by loosening a nut
The bundles Of cane, which weigh from
$50 to 175 pounds each, pass given point
at the rate of five bundles per minute
Eighteen men are required In its operation
for distance of two and three-fourths
miles, from loading to landing from the plat.
forms to the cars.
The OokaIa Mill.
The mill for handling the ookala product
is nine.roller mill operated by steam pow.
Grand having a capacity for turning out six.
ty tons of raw sugar In twenty.four hours
II is supplied with the latest modern appli.
ances, such as six CHARTERS, one 5, 8 and
lotion vacuum pans, triple effect four filter
presses and eight 30.inch centrifugals, max.
ing from 1900 to 1900 revolutions per min.
ute. The triple effect and vacuum pans are
operated by separate pumps of the Blake
pattern, while the centrifugals are driven
by separate Putnam engine
In order to economic I'm fuel all the ex-
haust steam from the triple effects and the
vacuum pans, is run into a hot well and
pumped into the boilers, thus giving the
boilers the benefit OF water that is heated
to from go to 20 degrees.
The nine-roler mill is operated by a $50
horsepower Hamilton. Corliss engine with
from 65 to 80 pounds of steam, the hydraulic
pressure upon the first mill being $50 tons,
upon the second 300 tons, and 800 tons pres.
sure Is applied to the last three.roller mill
Instead OF repressing the residual matter
resulting from the sugar boiling, which con.
tains more or less sucrose, is subjected to
dilution, thus reducing the density of the
Juice to per cent, after which II is put
through the mud presses and the extraction
is returned to the mill for maceration pur-
poses.
The mill extraction, averaged about Gals
per cent. The cane is delivered direct to
the mill by the endless carrier. the trash
being delivered to the fre-room automa,
tically and fed direct into the furnace. Two
grades OF sugar are made, designated as
Nos and 2. From the mill the sugar is
conveyed direct to the warehouse, at the
landing which has capacity of 5000 bags.
Transmission Of the sugar from landing to
steamer is performed by the aid OF a IA
inch steel patent Wire Locked" cable con.
