TWENTY-FIRST ANNUAL MEETING.

erything is enveloped in the mist which is forced into the foH- 

 age of the tree. 



Now in regard to using lead arsenate in connection with 

 other things. In the experiments carried on by Dr. Clinton 

 and myself in the last two seasons, we found the smallest per- 

 centage of wormy fruit where we used the lead arsenate alone. 

 In combining it with lime-sulphur and other things we did not 

 control the codling moth quite as well. Our smallest percent- 

 age was with the use of lead arsenate ; our next smallest, lead 

 arsenate and sulphur mixed together, and then comes lime 

 and sulphur, and then Bordeaux. Any one of these, however, 

 will control the codling moth, so that you could get a large 

 percentage of perfect fruit. In the last year's work our check- 

 trees showed an average of something like 12^4% of the fruit 

 attacked, while our spraying with lead arsenate alone kept it 

 down to 2%. With the Bordeaux it was only slightly over 

 3%. 



I think I will not take your time further. 



The noon hour having arrived, the other speakers in the 

 discussion of "Orchard Foes" were not heard and a recess was 

 taken at 12.45 until the afternoon session. The morning ses- 

 sion then closed was an exceptionally interesting and profit- 

 able one.
