fall-treated with spring-treated trees it is believed that the treat- 
ment of the latter was slightly more effective. Upon the upper 
parts of the tallest apple trees which were difficult to reach by 
the sprays quite a number of the fruits were spotted with the 
scale, but on the lower portions where spraying had been thor- 
ough the bark and fruit were uniformly clean. : 
GENERAL SUMMARY AND DISCUSSION OF RESULTS. 
The results obtained in the different orchards by the fall appli- 
cations of the sulphur washes show considerable variation in the 
effects of the treatments upon leaf and fruit buds. In Orchard 
I the spraying was accompanied by a reduction in the amount of 
the bloom and foliage. There was an average loss of 71.8 per ct. 
of the blossoms and 67.8 per ct. of the leaves upon the peaches, 
and 83.5 per ct. of the blossoms and 57.8 per ct. of the leaves 
upon the plums sprayed with these washes. The least destruc- 
tiveness was shown by the lime-sulphur wash which caused a 
loss of 82.7 per ct. of the blossoms and 27.1 per ct. of the leaves 
upon the peaches; and 61.5 per ct. of the blossoms and 33.1 per 
-et. of the leaves upon the plums. With the dropping of the 
blossoms there was a marked improvement in the conditions of 
the sprayed trees, which, with the exception of the smaller 
yield of fruit, ultimately equalled the checks in appearance. 
In Orchard II plum blossoms were reduced by 10 to 50 per ct. 
with slight injuries to foliage. The Morello cherries lost 5 per 
ct. of their blossoms. Apples and pears were similarly affected, 
and crabs sustained no apparent injuries. Trees much infested 
with scale were either killed or severely injured by the winter. 
In Orchard III the sprayed trees with the exception of those 
sustaining injuries by the scale and the winter were unaffected 
by the treatments. The sprayed apples showed later in the sea- 
son increased vigor and healthfulness as a result of the control 
of the scale. 
Owing to the variation in the results by the sprays upon fruit 
trees which is partly attributable to the severe winter the experi- 
ment has given conflicting data. For this reason a further study 
of the question under varied conditions is necessary before 
the exact effects of fall spraying upon crop yields in average 
years can be determined. The work accomplished shows that
