In the foregoing 1 have tried 70
show that il may be possible to induce
blight without infection, by improper
treatment and neglect As ProI WICK,

regarding the blight In that State- IL
is unprecedented that neither paying
crops nor living trees can be counted

is successfully kept under control Dy

some form Of natural immunity which
can be discovered or developed by plant
breeding"
In a series OF alLGltS on LIuAAS sun
ed to this section. published IN your
paper about three years ago, took up
this question Of breeding To limited
extent expected at that time TO de-
vote considerable time to this partic-
uIar work. viz: developing a pear that
would be immune TO this disease for
this section. but from lack OF appre-
citation and little encouragement did
not follow up the start made at that
time. It seemed to be the belief Of the
people engaged in planting pear or
chards that no harm would ever come
to the trees planted here and no i'm
Droyement was desired
Inspection Is Necessary.
Also. while acting as state inspector.
I received the i'll viii OF many people
because 1 inspected their incoming
shipments and charged them for my
time. and right here ] want TO say
think our inspection laws could be
greatly improved by the employment
of a competent inspector for this terri
tory upon a salary and not fee basis
He should devote all his time TO this
work. Every tree in this section
should be inspected and If affected,
either treated, or If badly infected, de-
Destroy Infected Trees.
Now, as to treatment OF trees found
to have the blight 1 would be in favor
OF destroying every tree found TO be
so affected as il is in the sap which
is circulated through the tree, and even
If not apparent. is still there
At this time only comparative rev
are so affected If the method of Gull
ing out the apparently affected parts
is adopted, there will most certainly be
enough affected parts left to distrib-
ute the disease
There must be local organization at
once. There is no time TO wait for
outside help, and while I do not expect
TO remain in this section much longer.
I will be glad TO cooperate and lend
any assistance I can in this matter
while I am here.
Let me impress upon the pear grow
eT again the importance Of action right
now. Every day increases the danger
and lessons the chances OF overcoming
this worst Of all pear diseases
