New YorK AGRICULTURAL EXPERIMENT STATION. 399 
On May 24 the blossoms were well open and the trees in row 
4 were then sprayed very thoroughly so as to hit as many of 
the open blossoms as possible. Immediately after the blossoms 
had fallen, May 31, the trees in Row 2 and 3 were sprayed on the 
west side only and on June 6 they were sprayed on the east side 
only. The weather conditions did not appear to favor the 
development of the scab fungus and no spraying was done after 
this. The treatment given to these Hubbardston trees for the 
season may be thus stated. 
Rows 2 and 3—sprayed just before blooming and just after 
blooming. ey 
Row 4—sprayed just after coming into full bloom. 
Liffect of the spray upon the open blossoms.—Soon after the fruit 
set a comparison of those trees which had been sprayed in bloom 
with those not so sprayed showed very clearly that many blos- 
soms had been killed by the spray. Although the bloom was so 
abundant that the loss of these blossoms could not be expected 
to make much difference in the yield of fruit yet at the close of 
the season the record of the yield actually showed less fruit on 
the average where the trees were sprayed in bloom than where 
they were not. 
With the assistance of Mr. Bradley the following estimate of 
the amount of bloom on each tree was made May 24,

An idea of the climatic conditions during the spraying season 
in Niagara County at Lake Road as compared with those in 
Ontario County at Geneva may be obtained from the following 
table. The observations for Niagara County were made free of 
| charge by Mr. H. A. Van Wagoner, to whom our thanks are due 
for this favor. The table shows the average of three daily read- 
ings of maximum and minimum thermometer, relative humidity,
