New YorK AGRICULTURAL EXPERIMENT STATION. 219 
Owing to the failure of the fruit to set the quantity upon the 
trees was very small and did not exceed on August 12 from two to 
forty per ct. of a crop according to the variety on either the 
checks or treated rows. The new growth and the amount of 
foliage of the sprayed trees was equal to that of the checks. 
The only apparent difference in the treated and untreated trees 
was that upon the lower branches of some of the former the 
number of the leaves was somewhat smaller. 
The results upon the Burbanks were about the same as with 
the above varieties. The conditions of thirty-six trees treated 
with the self-boiled lime-sulphur-caustic soda wash compared with 
that of uninfested checks appeared as follows: Trees not infested 
with scale had 85 per ct. of a crop of blossoms, and a full amount 
of foliage; moderately infested trees had about 70 per ct. of a 
crop of blossoms and a full crop of leaves; while the badly in- 
fested trees had from 0 to 35 per ct. of a crop of blossoms and 
about 65 per ct. of a crop of leaves. Trees of this variety that 
were much improved by the winter showed later a remarkable 
improvement in their conditions on account of the destruction 
of the scale. 
Morello cherries lost about five per ct. of the blossoms and a 
small number of leaf buds upon the lower branches. Apples 
and pears were affected in about the same degree. Crab apples 
bore a full crop of fruit and foliage. 
Effects on scale with boiled lime-sulphur-salt wash.—On August 
12, an examination was made of the fall treated trees to note 
their conditions in comparison with those of the checks and 
other trees which had received similar treatment in the spring 
only. There was no apparent difference in the results upon the 
scale by the fall and spring applications. Several pear and plum 
fruits exhibited slight markings by the scale, and at the base of 
the new growth of some of the trees there were small colonies 
of living scales. The incrustation which was composed of the 
old scales was lifeless and much weather-worn. 
With self-boiled lime-sulphur salt wash.—The results upon the 
scale by this formula were essentially the same as with the pre- 
ceding wash. While proving satisfactory in the present experi- 
ment this wash showed considerable variation in its effects upon 
this insect when used for spring treatment, indicating that the
