TWENTIETH ANNUAL MEETING. 79 



after picking-, in some cases they stood up two or tliree times 

 better. lUit these were only small experiments and were 

 not extensive. Someone said, 1 believe Dr. Clinton re])()rted, 

 they had used lime-sulphur 1-75, 1-100. That would be 

 pretty severe, to put 1-100 011 peaches. It would l:urn the 

 leaves off some varieties ; other varieties would stand it fairly 

 well, so where we have used commercial concentrate we have 

 used it about 1-200. Mr. Wallace has precipitated it and put 

 it on 1-30, and no harm, but that is not very practical be- 

 cause of the difficulty of keeping the stuff in suspension with 

 so much agitation. So the question of the strength in the 

 use of concentrates on peaches is one we are not ready to 

 make any conclusions on ; we haven't carried out extensive 

 enough experiments. All the experiments that we have car- 

 ried out were very favorable to concentrate. He used both 

 the commercial and the home-boiled, wdiich are the same 

 thing. 



One point in connection w4th that is that where arsenate 

 of lead Avas added to lime-sulphur and applied with a gas 

 sprayer, he got tremendous defoliation. He also got later 

 in the season defoliation where he used arsenate of lead in 

 lime-sulphur with the ordinary sprayer. He put on another 

 spray and worked it out and showed that the injury w^as not 

 due to the lime-sulphtir, but to the arsenic set free from the 

 arsenate of lead — arsenical burning. 



\'ice-President Drew : I \vill again call for volun- 

 teers to tell us the spraving troubles thev have had and the 

 success. 



Mr. P.rowx: I just wanted to say a word about the 

 results 1 have noticeil with lime-sulphur. I have not used it 

 personally at all, Imt one of my neighbors has got about 50 

 acres of orchard 10 years old, and he has got more burn than 

 others, and I looked over his orchard this fall, and the Ben 

 Davis in particular. 1 think that was worse than any other 

 variety. There was the worst case of burn I have ever seen. 

 The commercial lime-sulphur, we figured out, knocked a
