toon cane; total 3,525.5 acres; 24O.5 acres
short ration cane (estimated); total
Crop 19O7-3,766 acres.
The planting for the Crop of 1907 was
finished in very good time, being com
pleted on September Both and, although
the cane has suffered from attacks of
leaf-hopper, the general appearance of
the young cane is far better than cane
of similar age q year go.
Mill.-The excellent work done during
the LIST season proved the Mill to rank
with the best on the Islands and to be
up to date in every respect, 50 that no
expensive Improvements have been
necessary. The Mill machinery was
taken apart entirely and overhauled
between seasons. Three extra sand Al
ters were installed, in addition to the
eight filters already in use. This addi-
ton, together with a water-driven ele-
vatOr erected for the handling of the
sand, has proven a great improvement,
and will pay for itself in a short time.
The process of "sweetening off, the
press cakes, with which experiments
were made during last season, has, not
withstanding our limited filter press
capacity, been improved so that the
losses in press cakes have been reduced
from an average of 6l55 per cent to 1.SO
per cent sucrose, which on our present
crop would mean saving of more
than 100 tons of sugar.
A screw conVeyor for automatic
handling of the mud from the presses
to the cars outside of the mill has been
built from old material, and works
well, making a saving of men per
day.
Steam Pumps.-The great decrease in
the rainfall for the past year over that
of the previous one necessitated work.
ing the pumps to their full capacity for
fully ten months of the year. and the
cost of pumping has therefore been
considerably more than curing the pre-
vious year, although the cost per mil
lion gallons has been less.
The total cost of operating the Vari-
GUS pumping stations and the amount
of water delivered as follows: 1884,
O1S.16 and 1884, OO6, 424 gallons.
The average height to which the wa
ter was pumped was 391 feet and the
average cost of pumping to this ele-
walton per million gallons was $14 80 or
$3.50 cents per million gallons one foot
high. These figures include $1O,797.48,
the proportionate part of "Sundry ex-
penses" charged to steam pumps.
New Pump-The advantages of rails
ing large crops, made so apparent by
the considerable reduction in the cost
of production of the last crop, has in
duced us to take in 400 acres of new
land in Waip,o of which 1875 have been
planted for Crop of 1907, while the bal
ance viii be planted this year in addi-
ton to the area already under cultiVa-
ton. In order to provide water for this
new land, without endangering the
supply needed for the present area, a
new pump (No. 6B) was built at Wal
ava in the old Worthington Pump pit
This new pumps a 141a"x6O" Duplex
double-acting Lorenz Worthington
Pump, with a %" and 44"x6O" cross
compound engine, surface condenser
and direct connected air pump. Capa-
icty 6,5OO,OOO gallons per "a hours
against a head of 1916 feet The cost of
this pump, complete, with building and
4,450 feet of pipe line and a 300 H. p.
Sterling Boiler will be about $4S, 900, of
which 1872, 962.65 is embodied in the f.
nancial statement for last year in ad-
ditiOns to pumps. In connection with
this pump in order to be able to bring
the water on to the new land, it was
necessary to build an inverted Syphon,
1900 feet long, "a" diameter across one
of the gulches, about a mile of new
bitches, and a serervoir of million gal
Ions capacity, the total cost of which
was $7,OO6.75. This has already been
paid for and appears in last years
statement
Water Development.--Owing to the
great expense of pumping, and with
the example set by other large planta-
tions, it was decided to engage Mr.. ]. !
S. Molony, c, e., to make a survey of
the mountain gulches lying back of
the plantation, and to have him make
suggestions as to how our supply of
mountain water might be increased. !
Mr.. Molony remained with us from Oc-
tober 1904 to August, 1905, during
which time he went over the whole |
ground, and submitted a proposition /
which, however, entailed such a seri-
Gus expenditure, and was so great an
undertaking, that Mr.. M. M. O'Shaugh- !
nessey, c. E.. was called in to review
Mr., MOlonys plans. While Mr. |
O'Shaughnessey reported favorably on
the scheme, he made some suggestions |
which entail further survey and inves- |
tigation, so that the matter is still in |
In order to increase the water supply |
