crawls around, just where the lime-sulfur will not. That 

 is the beauty of oil. Am I not right, Mr. Frost? 



Mr. Frost. The soluble oils do that, they have that 

 property which all crude petroleum has, of spreading or 

 creeping on the wood. 



Pres. This question will bear further discussion. 



Secy. Brown. In regard to adding lime to the commer- 

 cial lime-sulfur, in my own peach orchard when I get 

 through spraying the trees look as though a snow storm had 

 struck them. I cook my OAvn concentrate or use the com- 

 mercial adding about four pounds of a very fine hydrated 

 lime, as a milk of lime which practically makes a whitewash^ 

 and the trees, after the first rain look as though they had 

 been snowed on. 



Dr. Gilson. I have tried lime. I don't know that it is 

 the latest improvement, but I saw no difference in the color 

 on the trees; I couldn't discern any. I don't know how 

 much I used, but I mixed up quite a lot. What I want is 

 something to add so that you can see distinctly where they 

 have been. 



Secy. Brown. Mine look like a snow storm and you can 

 see them half a mile away. 

 Dr. Gilson. Who^e lime? 



Secy. Brown. At first I used ordinary stone lime, such 

 as I used in making my lime-sulfur concentrate but I found 

 considerable sediment and grit and it was much easier to 

 use the hydrated form Limoid. I bought a few bags spec- 

 ially for. that purpose. I added about four pounds, already 

 mixed up in a buttertub to each barrel when the spray bar- 

 rel is nearly filled. A good agitator does the rest. 



Mr. Morse. I got hold of a bulletin somewhere that 

 said you upset the whole chemical combination of the com- 

 mercial lime-sulfur. I think it was the Arkansas Experi- 

 ment Station Bulletin. They said it upset the whole thing 

 by putting in more lime. 



Dr. Gilson. That is one reason I asked, whether you 

 could add more lime that would cover it and not injure the 

 combination. 



Mr. Castner. I don't believe there is enough added to 

 make any chemical change. 



Secy. Brown. I know that as far as I am concerned
