the mixture was ready for use. It is not improbable that this 
method will require modification, but as far as tested it promises 
to prove satisfactory. 
It is yet too early to make a definite statement as to the 
practical value of this or similar methods of making the wash. 
The mixture thus produced, however, has the general appear- 
ance of the wash made in the usual way, but although field tests 
are under way we have not yet satisfactorily demonstrated the 
_ safety or efficiency of the wash when made in this manner. The 
subject is presented at this time, therefore, as merely suggest- 
ing the possible value of this method. Should the method prove 
efficient after further trial, more definite statements will be 
made in a later publication. 
TV. SPRAYING EXPERIMENTS WITH OTHER WASHES. 
A number of compounds which have been recommended as 
remedies have been tested during the past season, both on Long 
Island and in Ontario County as follows: 
TESTS ON LONG ISLAND. 
These experiments were made in the orchard in which the 
other Long Island experiments were conducted. The trees were 
sprayed April 27 in the same manner as in the lime-sulphur 
experiments. The same check trees were also used. Three com- 
pounds were tested as follows: 
RESIN WASH. 
California formula.— Four peach trees, Early Crawford, Late 
Crawford and Elberta, and two Japan plum trees were selected 
for this test. Two of the peach trees were badly encrusted with 
the scale. The remainder were mildly infested. The wash was 
made after the following formula:
