New York AGRICULTURAL EXPERIMENT STATION. 330 
had a heavy foliage. On July 21, 4 trees were dead, one severely 
injured, and the remaining trees were slowly dying. Later in the 
summer all the trees receiving the treatment were dead. 
Hydrated lime mixture, 35 per ct. oil—Applications of this 
were made to four trees. On May 10, tree 1 was dead and the 
foliage on trees 2 and 3 was sparse. Tree 4 had a good crop of 
leaves and blossoms, but matured about one-third of a crop of 
fruit. 
Hydrated lime mixture, 40-per ct. oil—Four Burbank plums 
were sprayed and at the first examination on May 10 showed con- 
siderable reduction in blossoms and leaves on the inside spurs, 
although the outer branches were well covered. These trees had 
about one-fifth of a crop of fruit. 
In comparison with the above it is interesting to note the results 
on trees of the same variety in adjacent rows, which while they 
had been sprayed with the sulphur wash served as checks. These 
trees blossomed heavily and produced full yields. 
Orchard V: Peaches.—A block of fifteen young thrifty peaches 
in a well cultivated orchard and another comprising 58 trees in a 
neglected condition were sprayed with the 10 per ct., 20 per ct. 
and 40 per ct. mixtures on Dec. 5. Scales were abundant on the 
neglected trees at the date of applying the washes. 
Results: Limoid miature, 10 per ct., 20 per ct., 40 per ct. otl.— 
In the spring the younger growth on all the trees receiving the 
applications showed somewhat more extensive injuries from win- 
ter-killing than the checks. On Oct. 23 of the following autumn 
Mr. Sirrine reported that the trees which received applications of 
the 10 per ct. and 20 per ct. oil were in no better condition with 
respect to the number of living scales than the checks, but that 
the bark was somewhat smoother owing to the removal of the 
old scales by the weathering off of the whitewash. The trees 
receiving the highest percentage of oil, while they showed some 
improvement over the checks, were well covered with young 
scales. 
Effect on peach leaf curl.—In the spring following the treat- 
ment, the sprayed trees apparently had as much leaf curl as the 
checks. A count of the leaves on the sprayed trees showed an 
average of 76 per ct. of curled leaves, which was about the 
amount of the infestation of the checks, ;
