you can get it and then put it through a strainer. I have a strainer 

 made out of four inch white pine and I will put that right over the 

 middle barrel generally, so as to do it conveniently and thoroughly. 

 It is so thoroughly and intimately mixed by this method that you get 

 the very best compound that you can make. You will find by that 

 method of preparation that you will get a very much better mixture 

 than you will get by pouring one right into the other. It is very 

 simple and yet it pays to take that trouble. 



A Member: Will that combination do for the apple trees? 



DR. FUNK: Well, I will say that I use 5 pounds of lime to 50 

 gallons. 



MR. ESCHBACH: How long will it take San Jose" Scale to kill 

 the apple trees? 



DR. FUNK: That depends upon how thick they are on. It is sur- 

 prising to any one how thick they will cover the tree. You may 

 have a tree entirely free from it this spring, and by this fall you will 

 find it so completely covered that you will find the terminal limbs 

 all beginning to die off and one more season will finish it entirely, 

 right down to the stem. 



MR. J. B. JOHNSTON: Is there any successful machine for spray- 

 ing Bordeaux mixture in dust form? 



DR. FUNK: I have had no experience with the dust form of 

 spraying; in fact I do not think that in commercial orchards it will 

 ever be a successful thing. In the first place, to be beneficial we 

 would have to use it in the morning while the dew is on the tree 01 

 you will find it will have but little benefit; but those that are using 

 it, employ different machines, and they .claim fair results. I under- 

 stand that the Illinois Horticultural Society has condemned it as 

 of no account. For myself I can give no personal experience be- 

 cause I have never tried it. 



Mr. McGowan handed up a twig to Dr. Funk with the inquiry 

 whether it w r as infested with the scale. 



DR. FUNK: (After examining same.) Yes, there are plenty of 

 them there. 



MR. McGOWAN: I have two trees out of five hundred just like 

 that. 



MR. DAVIS: Would it be practical for a man to have a machine 

 and go around spraying so as to make it pay? 



DR. FUNK: Yes, and no. There are sections where they are do- 

 ing it and doing it with fair satisfaction. The only trouble is this: 

 The season of the year is comparatively so short, unless a man com-
