An examination of the treated trees May. 6 showed that the 
signs so visible on the previous inspection had: nearly disap- 
peared. The only indication. of the presence of the insecticide 
was a somewhat bluish. color, except in the case of one or two 
trees, where the lime, salt and sulfur solution appeared to have 
lodged in.masses and gave the trunk a somewhat speckled 
condition. Tree 4 produced a large number of flowers [pl..4], and 
95 had a very fair bloom. 
An examination of a few trees June 20 showed that there 
were many living young on the underside of the limbs of tree 
14. There were some living scales to be found in some positions 
on tree 18, and living females were abundant on. the: underside of 
the limbs of tree 12. 
A detailed examination of the trees was made July 5 with 
the following results. There were few.or no young on trees 4, 
5,.6,-8, 31, 50,55, 56,57, .58,. 76,96, 97, 98,99). thereywere' few. 
young on trees 10, 13, 32, 38,.49, 51,.59, 92; young were rather 
few on trees 29, 30, 52, 77 and 100; they were rather abundant 
on trees 7, 11, 14, 53, 78, 95; and they were very abundant on 
tree 12. 
Examination of these trees Nov. 6 by my assistant, Mr Walker, 
led him to rate them as follows. He found live females and 
young on trees 4 and 5 and dead young on number 6; numbers 
7-14 inclusive were in very bad condition; the same was true of 
29-33 and of 49-53, 55-59, 76-78 and 95-98. The status of tree 54 
was doubtful, and 93 and 94 had been removed. No living scale 
was found on tree 92. 
This is quite different, from the other end of the orchard, 
and it was so marked that it was comparatively easy to 
distinguish between those treated with the lime, salt and 
sulfur and those with crude petroleum, simply by the number 
of scale, insects on them. It should be pointed out however 
that this test was an unusually severe one; and, while these facts 
tend to throw considerable doubt on the value of this material, 
they do not condemn it. It is possible that the lime, salt and 
sulfur mixture will prove to be one of our most valuable methods 
of controlling this scale insect, since Mr L. L. Morrell, of Kinder- 
hook, who used the material under the writer’s directions, 
obtained most satisfactory results, and reports from others have
