6 feet away. I liave never been able to spray two rows of 

 trees at the same time. We get on the windward sid'e if we 

 want to do good work. I am afraid some of ns are over- 

 anxions about high pressure, and we break our hose and 

 over-tax our engine and tanks unnecessarily. That has been 

 mv experience. 



\'ice-President Drew: I think the vast majority of 

 us will agree with Mr. Frost and Mr. Lupton about that. 



]\Ir. Ives: 1 never have thought I could wait for the 

 wind to shift. 1 finish off my tree whether it blows from 

 one direction or the other. I believe I can spray a' tree all 

 aroimd and do it all up in one job, and I can spray up against 

 the wind with high pressure. 



\'ice-President Drew: I think it would be a good 

 thing to get from some of this audience some of their expe- 

 rielices in summer spraying, and I would like to ask some of 

 the gentlemen that have experimented this year with Bor- 

 deaux and with Hme and sulphur, if they would be willing 

 to give us some of their own individual experiences now ? I 

 think it is a most interesting subject and a mosf vital one, 

 and I would like to have someone volunteer without calling 

 on them. 



!Mr. Beardsley : Alay I ask Prof. Whetzel in the ex- 

 periment that he made wdth peaches, what mixture he sul> 

 stituted for the Scott mixture spoken of. 



Prof. Whetzel: Why, I am not very well posted on 

 the work wliich Mr. ^^'allace did with that lime-sulphur mix- 

 ture on peaches ; I have not the details clear in my mind, bi,it 

 I can give them to you in a general way. In 1909 he tested 

 out commercial lime-sulphur, the concentrate, the Niagara, 

 and he tried dilutions up to 1-200, testing out with the slide 

 method which I have described, and he found that 1-200 would 

 prevent germination of the spores, and trees sprayed three 

 times, finishing up just before picking, the rot was reduced 

 from one-half to two-thirds on the peaches sold. And where 

 he sprayed peaches just before picking, and dipped them just
