Respectfully submitted, 



J. H. FUNK, 

 J. H. LEDY, 

 Committee. 



The CHAIRMAN: Is there any action to be taken on this report? 



On motion, the report was adopted as read. 



The CHAIRMAN: Before taking up the regular program, there 

 is some time to answer questions on the papers of Mr. Schwarz, 

 Prof. Watts and Prof. Menges. If any of the members desire to ask 

 any questions in reference to any of these talks, if they will hand 

 them up now, they will be answered. 



DR. FUNK: Mr. Chairman, there have been a few questions handed 

 in that were not handed in last evening, and there was no oppor- 

 tunity afforded during the day to answer them. 



QUESTION: Is there any danger of the San Jose" Scale attacking 

 the forest trees?" 



DR. FUNK: Well, I think beyond doubt there are certain varieties 

 that will be attacked by the San Jose" Scale. They seem to have a 

 preference for certain varieties of trees, but then in case of their 

 not having the opportunity of feeding upon those, there is special 

 danger it seems to me that they may attack others. 



QUESTION: "Why not make up a stock solution of the lime, salt 

 and sulphur wash. You surely want it to last for several days or 

 weeks on the trees?" 



DR. FUNK: The reason we cannot do that is this: For instance, 

 you make up to-day a lot of the solution and you want to use it to- 

 morrow. The acid principle of the hydro-sulphate is thrown down 

 in the form of a sulphur-like crystal and it is not efficient unless it 

 is again reboiled, and it will take at least two hours before you can 

 again reboil as required and get them into an acid form, so it is 

 always advisable not to prepare more of it than you can use at 

 once. 



QUESTION: "Has Dr. Funk or any one in the audience any ex- 

 perience in spraying potatoes to prevent early and late blight? If 

 so, what has been the result?" 



DR. FUNK: I have had a good many years' experience in spray- 

 ing for the blight, and with very satisfactory results. In fact, I have
