The Area Involved. 
In Bulletin 131 I stated that the principal orchard growing sec¬ 
tions of this state were probably involved. It is now certain that the 
extent is wider than the boundaries of this state. There is no dispo¬ 
sition on my part to seek consolation in the fact that I believe

The Number of Trees Affected.

this difficulty. There are probably a few but not many. I know of an

vey a definite idea of how very prevalent the trouble is in some or-

apple orchard. Both of these orchards, though many miles apart and 
on very different land, are within this state. I have not visited the 
apple growing sections of the southwestern portion of the state and 
so do not know the condition of affairs there but in the rest of the 
state no section is entirely free from this trouble. It is found in Lar- 
mer County as well as in Otero, Fremont, Delta and Mesa counties 
and this represents a distance of nearly 350 miles from east to west 
and 200 miles from north to south. I am convinced that the number 
of trees already seriously affected by this trouble are not numbered 
by hundreds, but rather by tens of thousands. 
. n ^ ls . may not be an ^appropriate place to state again, as I stated 
in Bulletin 131, that publication on this matter was not the result of 
any sudden impulse, nor of any d'esire to obtain a certain notoriety by 
creating suspicion and alarm in the minds of any class of orchardists 
much less to protest against the general practice of spraying, but the 
publication was made simply because I was fully convinced of the 
sufficiency of the. proofs that great injury had already resulted from 
tne practice, particularly from the irrationally ultra manner in which 
■ ^ P rac ^i ce bas keen carried on, and that it was perfectly proper and 
n ght that the truth should be made known. The facts were presented 
conservatively. My colleagues agreed that it was wise to publish the 
results as simple facts. This is what I did and this is the only purpose 
that I have in view in the present bulletin.
