good for everything, even chicken Hce. (Laughter). But 

 lime-sulphur is not good for everything. And I think there 

 will be many other sprays discovered which will be more sat- 

 isfactory in time than lime-sulphur. I am not at all optimis- 

 tic that lime-sulphur will be with us" forever, even as long 

 as Bordeaux has b^en. So it is not surprising at all that 

 Ijme-sulphur will not cure everything. It is good, but there 

 is still that danger of burning from lime-sulphur, which has 

 always been there. 



Mr. Lupton : Then there is another thing ; we had this 

 year in Mrginia a most serious outbreak of cedar rust 

 (orange rust), and we found lime-sulphur was not a satis- 

 factory spray for cedar rust. Have you had any experience 

 with that ? 



Prof. \\'hetzel: We have some cedar rust in the state 

 of New York, but it is so slight as to cause little damage, so 

 I have had no experience in the control of cedar rust, and 

 it seems to me that until we have had several seasons' expe- 

 rience in fighting a disease with a given fimgicide and don't 

 get results that we ought not to be in too great a hurry to say 

 that it will or will not do certain things. 



Mr. Lupton : We had an experience with cedar rust 

 that defoliated hundreds of orchards and russeted the apples 

 themselves so they were not merchantable. We have had 

 attacks of bitter rot which spread over two weeks in the hot, 

 muggy weather, and the apples turned black on the trees al- 

 most over night, and we have not found that lime-sulphur 

 will control those attacks as yet. I didn't know whether 

 you people were suffering from these pests or not. 



Vice-President Drew : I would say I had quite an 

 experience with that this year, particularly on W^ealthy, and 

 I tried both self-boiled lime-sulphur and commercial lime- 

 sulphur, and it did not control it. 



Dr. Clinton : In our experiments we had more rust 

 than any other fungus, and the average of rust on the sprayed 

 trees was just as great as on the unsprayed, and it didn't
