INSECT PESTS.
/ The lc1f-hopper and the black aphis,
which affected the crops of late years
/ to "a great extent, are stfl in evidence,
although perhaps not so numerous as
"a year ago. The fact. however. that
the hymenopterous egg-parasite, rec
Gently introduced from Queensland
through the chronological Division Of
the II. S. p, A. Experiment station
has established itself ON the plantation
is very encouraging, and there is no
doubt that by close attention To the
further propagation and spreading of
this insect the ravages of the leaf

MILL.
The improvements made i'm the mill
between seasons proved fully efficient.
The boiler capacity was enlarged with
two boilers of 1900 square feet heating
Surface each, early i'm last season. and
later before the mill started on the
Z present crop, there were added two
other boilers of 200 square feet heat
| ing surface, and the economisers We're
thrown out. The installation of these
four boilers did not necessitate any en-
b largement of the building, as they were
/ placed on the top of four of the old
boilers. With these extra boilers the
l amount Of steam produced was enough
e to stop the use Of extra fuel besides ba-
gasse, and to supply power to run 5
million gallon pump in Waipahu gulch
} by electrical transmission.
The twelve roller mill was quite a
successful installation, the figures on
the mill report speak for themselves.
The strengthening Of engine founda-
ton and intermediate trash carriers.
as well as the new trash screen and
elevator has insured a reliable work
: ing of the mill machinery.
/. \ quadruple effect of $500 square feet
- heating surface. bought from Keala
r Plantation, was improved upon by
heightening the bodies and inserting
e. proper save-alls. The installation of
e this quadruple effect was completed
+ i'm the latter part of last season and
$ was tested 1t has this season proved
a very valuable addition to our eva
7 porating plant, enlarging this by 80 pei
I cent.
Six 80" centrifugals, also bought from
! Kealia, were supplied by water driven
arrangement and installed i'm the
=. month of April, 1904 The increase OF
centrifugal capacity was very neces-
sary, and while it would admit of still
: further additions, has been of great as
=. sistance i'm bringing up our daily output
to its present figures.
/ The mill is making a splendid show
I ing this season. We are grinding an
l.. average Of 1,4OO tons Of cane per day
and have several days made runs of
3, over 1,5OO tons. with AN extraction of
, 95.2 per cent to 95.6 per cent.
5 The total cost of operating the six
! water delivered by them was $40, 435. 10
:. and 1O,596623.5O5 gallons.
The average elevation was 3S7ia feet,
and the average cost of pumping to
this elevation, per million gallons, was
= $l6.OS or 4.l5 cents per million gallons
j one foot high.
The average pumping days were
1882 and the average quantity Of wa
j ter delivered per day amounted 90
54.44E7G2 gallons for that period to an
elevation Of 1917 feet.
In examining the cost of pumping it
4 is necessary to take into consideration
6 the high elevations to which the water
had to be pumped, and | believe thai
f tie COS of pumping will well bear COM
parisou with TIE same expense on any
n Other pumping plantation in the ISL
