out of the fuel used, but saves enough fuel
to dry of all the low-grade sugar between
seasons.
The mill has a capacity for turning out
from twenty-five to thirty tons of sugar per
day of twelve hours, and is operated exclu-
sively upon sugar cane produced upon the
lands Of the Kukaiau Plantation Company.
All the cane is delivered to the mill by the
plantation company by he horner system
OF aerial transmission, while all labor in and
about the mill is under the control of tho
management of the mill which Is In the
hands of Z. Madden, with George Osborn"
as chief engineer.
The output of the mill for the season Of

The method of shipping the product of
the mill to market Is quite interesting. A
short distance from the nal double incline
tramway has been constructed 200 feet In
length at the bottom of which ia a large
landing platform built on the solid rock
upon which a large crane has been erected.
From the top OF this incline the cars are
loaded with fifty bags Of sugar at time aud
controlled In descent by an endless wire
cable winding upon a drum which Is oper.

boats are then sent from the side of tue

sacks, weighing 100 pounds each, and swung
around over the boats manned by natives
who understand their work. The amount
of sugar that can be handled In q day in
this manner Is something remarkable.
T.. Madden is the manager of the Kukaiad
mill with which he had been identified for
fourteen years as sugar boiler. Two
years ago he became the mill manager.
