piled from the pumping systems ana l0VD
acres from mountain supply. The system Vt
cultivation is irrigation and fertilization
using about 800 pounds Of high.grnds Ter.
,...zer and 200 pounds nitrate Of soda to
the acre. For the 1903 crop. which is now
being planted. there will be So per cent plant
and 10 per cent of rattoons. The 1901 crop
was from 1000 acres realizing in the mil
656S tons Of raw sugar. The estimated crop
for 1902 Is 10000 tons of raw sugar from
100 acres, while the 1903 crop is estimated
at about $4,000 tons Of sugar from 2100
acres.
The method Of conveying cane from field
to mill is ny railroads and fumes, static rs
being established where necessary; the
cane Is conveyed by fumes direct into the
cars and thence conveyed to the mill. The
length of the main trackage upon the plan.
tation is about twenty-five miles. which Is
supplied with 300 cane cars, having an av-
erage capacity for holding three tons, which
are transported to the mill with engines OF
sufficient horsepower.
At the mill the cane Is delivered from the
cars to the endless carrier by the aid ot
the Gregg automatic cane car unloader.
which Is supplied with four sets OF sprockct
chains and steel teeth instead OF lne regi-
lation style Of two sets. from the cane
carrier the cane passes to kraJewskt
crusher, from whence II passes through
modern triple Stroller mill (9roller MILL,
capacity 1875 tons in twenty-four hours, or
between sixty and seventy tons Of raw
sugar in day Of twelve hours.
From the mill the bagasse is conveyed
automatically to the furnace room AM
dropped directly to the .tisdon automatic
furnace feeders. The mill Is practically a
new structure and was built by the Honolulu
Iron Works, and is supplied with the most
modern appliances for manufacturing raw
sugar, such as Juice strainers and elevators,
Deming super-heating apparatus, bog filters,
settling tanks, Lille effect, one Honolulu
and two German vacuum pans, twenty-five
Hepworth centrifugals driven by separate
power. six filter presses and much other
machinery. The management Is now erect
ing a sugar elevator conveying the sugar
from the centrifugals to higher hoor, fr0 II
whence It is dropped down to the bags. by
this method all snoveiing OF the sugar into
sacks is dispensed with, and the sugar
given an opportunity to cool on before
being sacked.
Two grades of sugar are manufactured
and known as and B; all other grades ara
returned and worked over again into the
above two grades. Water for general mill
use is obtained from wells sunk upon the
mill site. over which have been erected two
5000, O0O-gallon Worthington pumps. All
water emanating at and not required In the
mill goes into the irrigation system, and is
utilized to irrgate a large area OF cane be-
low the S0-foot level. Maceration OF from
IL to Is per cent Is carried on In the mill
by utilizing the condensation waters from
the triple-effect.
The average yield OF all cane product put
through the mill is approximately seven
tons OF raw sugar to the acre, or forty.nine
tons of raw sugar to the acre, or hfty-six
extraction of sucrose In cane for the season
OF 1901 was 80 per cent, the juice In the
cane standing high more especially In stonT
lands. From the mill the sacked sugar is
