4. June 23d, a part of the trees of lot 3 were again sprayed with 

 one pound of London purple to 200 gallons, and adjacent trees, 

 which had not been treated, were sprayed with one pound to 256 

 gallons. All the trees were very badly injured, and nearly all the 

 leaves w h i c h

 foliage. Some 

 of the shoots had

 application. The

received no previous treatment were injured as much as the others. 

 5. A number of young and very vigorous trees in a third 

 orchard were sprayed June 23d, a part of them receiving London 

 purple, one pound to 256 gallons, and the remainder one pound 

 of Paris green to 200 gallons. Several varieties were represented 

 in these trees. In three days the trees receiving London purple 

 began to show signs of serious injury. Crawfords suffered much 

 more than Old Mixons, but this may have been due to some 1111- 

 evenness in spraying, although care was exercised to treat all 

 trees alike. In four and five days the leaves began to fall. In 

 seven days the leaves were falling badly, and at this time some 

 injury began to be apparent on the trees treated with Pari.s green.
