ruary LIST there had been completed TO-
200 feet of tunnel. and 400 feet Of open
ditch Work is being carried on night
and day and t is expected that the
ditch and the Wahiawa Dam will be
completed at about the same time
"Wahiawa Dam.-The cost of the
construction of the Wahiawa Dam is
not carried as a permanent improve
ment account, this work being done by
the Wahiawa Water Company, Limited
The most difficult and expensive part
of this work is now finished. The pipe
line and outlet tunnel are completed.
with gate valve and tower. The re-
lief dam, for diverting the water of the
stream and the tunnels for carrying
it off while the dam is being built, are
finished, and the water is now running
through the tunnels. A concrete cut
off wall has been built to depth of
about 40 feet below the bed of the
stream $4,000 cubic yards of rock
have been quarried. Four and a half
miles of railroad track built to the
quarry, crushed rock prepared and
cement, lumber and other materials
bought and paid for The actual build
ing of the dam is now going on, and
if there are no unforeseen difficulties
the dam should be finished by July 1st.
work should settle one of the greatest
difficulties that has, been met i'm the
development of the Waialua planta-
ton viz: the great cost of water for
irrigation when pumped, and the limit
ed area of land available for planting
| b ,low the elevation to which water
can be pumped with profit. When this
dam and the bitches are finished there
will be about II 900 acres Of land that
can be irrigated with mountain water.
THE building of the dam is carried
! on under the direct supervision of L. G.
| Kellogg, manager of the Wahiawa Wa
ter Co.. Ltd, with H. c. Kellogg, of
| California as consulting and construct
ing engineer.
Insect Pests.-The cane borer is still
to be found in some of the fields. The
cane for the crop of 1905, now being
harvested, has not been as seriously
affected as the crops of 1903 and 1904,
| During the year 1904 1,1S2. 492 beetles
were collected by children and des-
! troyed This system has been carried
on for two years and has reduced the
loss from borers.
"The leaf-hopper is present in all of
our fields, but we have the Fairchild
parasite also. These parasites are
collected in fields where they are most
numerous, and have been distributed
all over the plantation. The new pa
rasite just brought from Australia has
been started i'm two places, but so re-
Gently that no effect can yet be seen.
1.-THE rust, or top-rot, one of the most
serious pests, is not in the department
| of the entomologist, but of the plant
pathologist."
