however by ascertaining the amount OF
moisture remaining in the trash after crush
ing, weighing a quantity of trash lust rom
the rolls. drying il thoroughly, and weigh
ing again. Rhe loss i'm weight viii be the
amount of moisture to be ascertained.
Tested in this way, the trash from the II.
c. Co.'S Mill was found TO contain % per
cent. of moisture, or in other words, from
100 lbs of cane, II lbs of juice were obtained,
and of the residue, IL los were moisture,
and Is lbs dry trash. Although the largest
mills crush nearly if not quite rs efficiently
as this, If seems that with the five roller
arrangement, a much larger amount of
cane can be put through i'm IA given time
than with the triple rolls Of the same size.
Immediately in front of the three last sets Of
five roller mills are three triple effect houses
where the Juice is evaporated ut low tenn
perature, from there il goes through pipes
and is pumped into the two new vacuum
pans which are in the top story of buildings
Immediately in front of the triple effect
houses. One of these pans il twelve feet in
diameter and will hold over thirty tons of
sugar at a strike, il Is used entirely for
No. l sugar. The next one a ten foot pan
is used for No. , and 8 sugars. After being
boiled in vacuum the sugar drops down
from the pan into "a large iron trough that
feeds the centrifugals, of which there are
eight to each vacuum pan or in ali "a.
From the centrifugals the sugar drops
through the bottom TO the sugar room
where il is packed into bags and put on to
the hut railroad ears right at the door

drives the three sets of rollers, the triple
effects, vacuum pans and centrifugals, etc,
etc, is generated by fourteen immense
double boilers in one large boiler house and
the steam connections with all parts OF the
works are laid underground in cemented
trenches covered over with corrugated iron.
Besides the above there are in the first
works erected and not connected with the
last works put up, the boiler house contain
ing five large double boilers, one large triple
effect, one ten foot vacuum pan, eight CEN
trifugals, and one five roller mill, besides
the Engines for driving the mill etc.
There are on this estate over 20 miles of
tranrway, about II miles of this is a perma-
nent double track laid through the main
roads, the balance is portable, and is put
down i'm the different fields TO connect with
the main tracks as fast as required, the
gauge is two feet, two Locomotives are used,
and they haul the one thirty and the other
twenty cars, each carrying about 5000 lbs.
of cane. Mule power is used To draw the
cars from the field on TO the main track,
where they are made up into trains and
hauled to the mills by locomotive. The
large reservoir near Puuncne, is full of
water, the area is many acres, and has an
average depth of twenty feet, all the water
from the main ditch is run into this lake
at night and drawn Off for irrigation every
day. The large reservoir beyond Haiku
will soon be completed, il is intended for the
storage of water that the ditch is unable TO
carry in winter, and il will hold an inn
mense body of water, and enable n much
larger area to be put into cultivation than
is now planted.
No stoppage or hitch has occurred with
machinery or anything else since the works
were put up. Every thing has been on the
most liberal, yet in the end, most economi-
cal scale; the results so far are that the
sugar from this estate has cost landed In
warehouse at Kahului, exactly two cents
per pound. This includes labor of all kinds
expended on preparing the land for the
seed, wedding, stripping, cutting, hauling,
hOilinn f1al nnNVar and pVpry inpinanfal
in connection with running expenses on
this estate, except interest on actual cost of
construction of ditch and erection of works.
BY the end of this year the cost will be
further reduced to about one aud JiUe-
eighths Of a cent per pound.
Mr.. Spreckels can very well do without
the treaty, when he can raise yearly say
5000 or more tons ofsugar ut this low cost;
for it gives him the control of the San
Francisco Market. No other refinery could
compete with him on the coastA when ne
could lay down his own raws there at
Neast two cents per pound less than his
competitors could from Manila or elsewhere.
The present yield of sugar per acre at
S~preckelville Is very satisfactory. "A field
of 800 acres taken off last month averaged
over four aud One-fourth tons, and another
section yielded full five tons, and this from
land formerly lying utterly waste, and a
desert.
They are now cutting a section that Is
yielding six tons TO the acre the juice
stands exceptionally high, averaging from
eleven and one-fourth to twelve and one
half, Baume OF this years crop, there is
now off about 1000 tons-the expected yield
for 1882 is somewhat over -, 900 tons.
In addition to trash consumed as fuel il
takes one-third of n ton of coal to every
ten of sugar made.
Captain Hobron's railroad is kept as
busy as it can run, sometimes night and
day, carrying sugar from Spreckelsville and
taking back supplies in addition to running
to Paia, a little beyond spreckelsville
for sugars of East Maui, Grove Ranch,
and Alexander & Baldwin's plantations.
The harbor accommodation are rather
too small now at Kahului for the extensive
shipping business now done there-A first
class wharf out to deep water is much need
ed.-So also is an artesian well for the resi-
dents of that growing young city. The
present drinking water for Kahului having
to be brought on the cars from Wailuku.
