In competition with the CONT

More than two-thirds of the three
column page of the magazine is taken
up with technical analysis of the
cost of refining in the raw sugar fac
tory, of which only the found results
can be quoted here. Expenses for the
boiling and the centrifuging of the
additional quantities of massecuite to
be treated in the factory on account of
the refining make total of $25 a day
on a grinding OF 1000 tons of cane.
The 1000 tons of cane are given a
yield of 112 IL tons. or 1000 pounds
of white granulated sugar per day, on
which the total of refining expenses
is $3.50, or about 20 cents per 100
pounds of granulated. -..... .

takes the Try conservative estimate
of 80 cents, and gives figures to show

the value of about 12 gallons of mo-

instead of so cents, the profit per ton

Notwithstanding that the Hawaiian
planters are conducting exhaustive
experiments with the locally Invented
Battelle process for producing refill
ed sugar in the factories. this account
of processes in vogue and under ad-
.visement elsewhere cannot fail to
possess much interest for people here
in the present situation of the sugar
industry, depressed as it is with low
prices and the menace of the abrOga-
ton of protection to sugar. The ar
tfcle has the following conclusion re-
specting beth methods suggested for
deliverance from the thraldom of the
refiner: II.
The complete refining is the only
method by which both the perfect
quality OF the granulated and the
maximum WELD can be secured.
