and discussion Of the report Of the ex-
pertinent station committee but a
supplementary report on that sub
nitted by the committee on forestry
was contributed this morning by DR..
H. l.. Lyon.
In this supplementary report DR.,
Lyon pointed ont that the Hawaiian
sugar industry which depends a great
deal on water. will suffer unless the
present watersheds arc rot reforest-
ed.
The native forests are doomed.
said Dr.. Lyon. and in no great time
their efficiency will be practically
negligible"
He suggested action now along re
torestra;io1 lines and pointed out that
thr ;cas0n the native forest is dying
is because in the first place it is com
posed o: troos which are used to new
made soil e1d that secondly the trees
Eow composing the watersheds are
rot p-ot ected as they we're before
the period of susar cane cultivation
when forests ran from watershed to
tho Sos.
OR forcIt is O: the very ancient
order It Is Believed that these is
lands wee once part OF the Asiatic
continent and ;hat shortly after this
land was formed the trees and plants
which seek new-fOrmed land spread
here to what was then part Of the
Asiatic continent"
When this land became divided
from the mainland the flora and fauna
which grow on old soil could not
come and hence only trees that seek
new made lands have been here. Now
these trees are dying because the soil
has changed and it means that we
must reforest our watersheds with
society Of trees, vines and plants 51at
will hold water and that will find this
old soil good to thrive in"
DR.. Lyon suggested that tree nur.
series be established, one on a noun
tain and the other in lowlands. where
experiments could be conducted to
discover which trees would prove
best for the reforestation of the plan
tation watersheds.
In the discussion which followed
the reading Of the experiment station
report it was brought out that the leaf
hopper pest has not been solved yet
but the members Of the association
were undoubtedly pleased when the
report informed them that the scotia
wasp had proved an effective parasite
on anomala. Mr.. o. H. Swezey of the
station said that colonies of the
scotia wasp were being sent out to all
plantations by the station wherever
the anomala made its appearance.
On the subject of the leafhopper
which has worked such ravages in
certain plantations Mr.. Agee admitted
that the solution of the problem had
not been reached chiefly because the
staff of the station had not had the
time to study it, but that in the near
fuure the leafhopper would be given
considerable more attention than in
the past.
The cane borer situation was we'll
in hand, the report read, except in the
Kona district where attempts made
to kill the pest have failed. H. P. Agee,
director of the station, admitted in this
connection that there was a possibility
that the parasite was being killed by
some larger pest.
F. NJ. Anderson of Hawaii reported
that the cane borer was his most
serious enemy, and R. S. Norris also
spoke along the same line. Prof. r.
Veitch of Fiji who happened to be
present was called upon to give his
experiences with the cane borer in
Fill.
On the subject of eyespot disease
DR.. Lyon addressed the meeting and
brought forth samples of cane to show
that some varieties were more sds-
ceptible to the disease than others.
The yellowstripe disease on striped
tip cane was next discussed and it was
generally agreed that the experiment
station had been right in recommend
ing the gradual substitution of other
varieties.
A short discussion on infectious top
rot, leaf sheath rot and nematodes
ended the morning session.
