318 Report OF THE DEPARTMENT OF ENTOMOLOGY OF THE 
DETAILS OF CO-OPERATIVE EXPERIMENT IN 1906. 
In 1906 the entire orchard was sprayed in the spring, while the 
trees were dormant, with the boiled lime-sulphur wash. The items 
of expense and the entire cost of treatment are as follows:

RESULTS ON TREES AND SCALE BY SPRAYING IN 1906. 
At the time of blossoming there were no evidences of injury by 
the applications of the sulphur wash, and the general appearance 
of the trees was better than at any time since the summer of 1903, 
which was largely due to the great improvement in the condition 
of the Greenings. The trees were carefully examined through the 
summer for the first appearance of the spotting of the fruit, which 
was detected on a few apples on a number of trees on July 27. On 
August 11, the orchard was in better condition with respect to scale, 
at this season, than it had been for several years, and as there was 
very little evidence of the spotting of the apples, a clean crop of 
fruit was expected. But during the latter part of August, and 
through September especially, which was remarkably dry and warm, 
the scale was unusually prolific, and there was more or less spot- 
ting of the apples; but they were not, in this respect, unmarketable.
