Pianters' Experiment Station.


P1anterf Experiment Station.
The so-called manufacture Of raw
cane sugar consists, in the simplest
terms, OF the recovery. liz the form OF
small crystals, OF the sugar which Is
A solution In the cane iuice. This
recovery involves, III general trims,
the extraction o. the Juice from the
cane by pressing, the elimination Of
those constituents of the juice that
can be preeipitated by heat and
chemicals, the evaporation Of as much
OF the water "a is necessary to ALLOW
the maximum quality Of sucrose TO
cfystallize out, and the separation of
the sncrose crystals from the mother
liQuoF.
In this process of recovery it is the
constant endeayor OF the Hawaiian
Plantations TO make use of the very
best machinery and methods that are
known, For the purpose Of fncreas-
Ing the efficiency and economy OF
manufacture there Is constantly being
tried opt on our plantations new pro-
cesseF and rev forms OF machinery
Invented here and in other cane sugar
countries. It is in this way that Ha-
wall has earned the reputation Of
being In the lead over all other cane
sugar countries in the manufacture Of
sugar as well as the growing of cane.
A few quotations from authorities on
this subject will bear me out in this
statement Fl. G.. Prinsen Geerligs,
the well-known authority OF Holland
and Java. in HIS book. The Worlds
Cane Sugar Industry" says: the
Manufacture of sugar from sugar cane
n the Hawaiian Islands is carried on
n the very best possible way.
Their factories are Installed with the
best machinery 20 be had"
Professor Geo. T. Surface of Yale
University, in his treatise on the
worlds sugsr industry. The Story
81 Sugar" says. Hawaii leads the
canesgrowing world in the mechanical
facilities OF her mills.
Mr.. Noel DEER, the English cane
sugar expert. formerly technologist at
this station. in his report 10 the secre-
tary Of agriculture OF Cuba on the
sugar industry OF that island, uses the
cxpression In the highly efficient
and highly organized industry in Ha-
naii.e IN comparing the industry in
that country and in this.
u order to show how Hawaii com

tories, and how rapidly new machinery
and methods are adopted after they
have been demonstrated TO be Inn

review the different divisions Of the
manufacture
Il was demonstrated ON these Is
lands that the highest results in the
extraction Of the Juice from the cane
cannot be obtained with less than four

the longer trains of mills spread after
their increased efficiency had been
