The total number of leaves examined is 802, of which 406 were 
from trees treated with the sulphur wash and 396 from untreated 
trees. The number of fruits examined is 48, of which 25 were 
taken from sprayed and 23 from unsprayed trees. The worm- 
injured leaves from the sprayed trees averaged 13.9 per ct. and 
from the unsprayed trees 71.7 per ct. The worm-injured fruit 
from the sprayed trees averaged 9 per ct. and from unsprayed 
trees 50 per ct. Thus of the number examined there was 57.8 
per ct. less worm-eaten leaves and 41 per ct. less worm-eaten 
apples from the sprayed lot than from the unsprayed. Judging 
from the appearance of the foliage at the time of the examinations 
it is believed that these figures closely represent the conditions 
of the leaves of the sprayed and unsprayed trees. 
In the Carlton Station No. 2, orchard which belongs to Mr. 
Albert Wood, 74 apple trees, consisting of the varieties Twenty- 
Ounce and Roxbury Russet, were used for the experiment. These 
trees were old and of a very large size. During the past ten 
years they have been thoroughly sprayed for insects and fungous 
pests. Because of this careful treatment, the case-bearer and bud- 
moth were not numerous enough to be injurious. For this reason 
no results were obtained upon the value of the sulphur wash for 
these pests. There were no evidences of the work of the codling 
moth upon any of the trees. Because of this no count was made
