of explaining to the representatives
the working facilities of the new ma
chinery recently imported and set up
under the direction of Mr.. J. +.
O'Neil, superintendent of the Fulton
Iron Works, of st. Louis, Mo.
The party, consisting of E. d. Ten
ney, n. NJ. Whitney, Sr., editor Of the
Planters Monthly; Dan Logan, editor
of the Daily Bulletin; Ed. Towse, edi-
tor of the Star, and w. n. Coney,
representative of the ADVERTISER,
were met at the Eva depot by w. J.
Lowrie, manager of the plantation.
A few points of interest were point
ed out concerning the exterior of the
mill, after which the party were con-
Quoted inside by Mr.. O'Neil, who ex-
planned the machinery in use.
The engine which runs the mill was
made by the Hoover, Owens & Rent
schler Co., of Hamilton, Ohio, which
is In connection with the Fulton Iron
Works, of st. Louis, Mo. 1t was from
this latter company that the Eva
plantation purchased the entire ma
chinery.
: MT. H. P. Baldwin, of Maui, while
visiting in Louisiana, was much i'm
pressed with the working of one of the
Hamilton Corliss mills in that State.
On his return he recommended the
machinery and the Eva Plantation
Company took up the matter and
afterwards purchased the largest en-
gine and mill on the islands and like
wise the first of the kind ever put up
In the country.
The engine is a Hamilton Corliss
automatic, % by 40. The driving
wheel is twenty feet in diameter and
weighs fifteen tons.
The mill is 81 by IS, and is driven
by five large compound gear steel
wheels and contains nine steel alloy
rolls.
From this can be obtained 80 per
cent. extraction, with guarantee OF
81 per cent. by the Fulton Company.
The pressure in tons on the first set
of rolls is 275; on the second, 285, and
on third, 295. This is regulated on the
top rolls by the Fisher patent hydrau-
lie. By this mode the thickness of the
feed has not to be taken into account.
If the feed is thick the top roll is
raised, and il thin it is lowered again,
insuring perfect safety guard.
A Is per cent. maceration is used on
the second set of rolls, insuring the
more complete extraction of the cane
juice.
In the nine-roller mill the work is
distributed much more evenly than in
the old six-roller one, consequently
there is less wear and tear.
A slot chain in the intermediate
carrier takes the cane with perfect
ease, doing away with the old-fash-
ioned feeders.
The old mill had a capacity of from
eleven to fourteen feet per minute
with a thick feed, while the new one
runs twenty feet with thin feed, with
perfect safety.
The new mill has q capacity of 567
tons of cane per day, while under the
old system about half that amount
could be handled. It is expected that
capacity of 700 tons will be reached
soon.
One of the most interesting facts
about the mill is that coal is no longer
necessary to be used. The trash is
dried and dropped into the furnaces
by means of two Young and six Rls-
don feeders. No firemen are required,
and the services of one or two men are
all that is needed to place the fuel
where the feeders can catch it. In
this connection the railroad company
will lose the hauling of 5000 tons OF
coal V ear from Honolulu to the plan
tation.
After a careful inspection of the
machinery, the chemist, DR.. Pohl-
mann, explained the process from the
time the cane enters the mill until 1t
is turned out as >ugar.
The juice is first pumped into one
of two large tanks in which the Gus
tomary lime is placed. From there it
flows into larger tub, and - carried
into the supeIheater, where 1T Is
warmed slightly in preparation for the
next step-the separator, where the
heat ranges from 240 to $50 deg.
Here the steam is driven back into
the superheater for use of the next
installment, while the juice is passed
back through the inner coils of the
receiving tanks. 1t is then run into
settling pans, from which place the
mud is passed into mud presses and
the juice into the evaporator. The
