New York AcricuLturaAL EXPERIMENT STATION. — 310 
pounds, sulphur 15 pounds and salt 15 pounds to 50 gallons of 
water. On April 14, 1905, eleven trees were sprayed with the self- 
boiled wash. A few trees were left unsprayed to serve as checks. 
Results on blister-mites: —In the spring of 1905 the trees were 
examined frequently by Mr. Sirrine to determine the effects of the. 
treatment upon the trees and the mites. On March 27, he reported 
that a number of the fruit spurs on the trees sprayed with the 
self-boiled wash were dead, while the remaining trees, including 
the checks, sustained no apparent injuries. At this time the mites 
were abundant under the bud scales of the untreated trees while the 
sprayed trees showed little or no infestation. The mites were still 
present under the buds on April 20, but by the 24th they were 
migrating from their hibernating quarters to the unfolding leaves. 
Eggs were also detected under the bud scales. By April 30, some 
of the mites had burrowed their way into the unopened leaves, 
causing the usual reddish spots. There were no traces of mite 
injury upon the fall-treated trees but on the spring-sprayed trees 
there were a few affected leaves. The checks appeared in marked 
contrast with the treated trees as many of their leaves were much 
discolored and sometimes distorted by the work of the mite. May 
4, eggs and mites were abundant on the unfolded leaves. Many 
galls were examined for larve and eggs without results, June 3. All 
the trees were badly infested with Gymnosporangium sp. which 
made it difficult to distinguish the blisters of the mites. The dis- 
ease at this time seemed to be the more destructive. The condition 
of the trees with respect to infestation by the mite showed no appar- 
ent variation from former observations. 
ORCHARD II: PEARS. 
This orchard is located about three miles from Riverhead, Suffolk 
County. It consists of 130 Keiffer pear trees which have been 
planted two years. These have been given careful cultivation but 
have not been sprayed until the present experiment was conducted. 
Conditions: — On April 8, 1904, twenty of the trees were sprayed 
with the self-boiled lime-sulphur-caustic soda wash, the remainder 
being reserved as checks. One application of the wash was made, 
which, on account of the small size of the trees, was very thorough.
