Mr. Ives : How does that solution test that you have 

 just spoken of? 



Mr. Henry : It ous^^ht to test 24-27 degrees, I think. 

 There are a good many bulletins on this which the growers can 

 get. With the 24 to 27 test, we can dilute to about one to 

 six, or something like that. That gives you a spray with some 

 sediment in it. We prefer to make it up, because then we 

 have got it on hand when we want it. 



President Rogers : When you say, dilute it one to six, 

 do you use that strength on the trees with the foliage on? 



Mr. Henry : That is for dormant trees. You can use it 

 on cherries and apples about one to forty for the 32 degree 

 test. That should be about one to 32 or 33 for what a person 

 makes up. That should control the leaf spot on cherries. And 

 that is what is used on apples and pears a good deal. 



President Rogers : Aside from the heating of the lime 

 in boiling, is there any difference between it and self-boiled 

 lime-sulphur? 



Mr. Henry : There is hardly any dift'erence in it, only 

 you just use a different formula. It is the same tools and the 

 same apparatus, only a dift'erent formula. It is practically the 

 same as Dr. Stewart has told us about to-day. 



Mr. Fenn: For summer sprays what proportion do 

 you put on, I mean what is the proportion of the mixture? 



Mr. Henry : One to thirty or forty. It depends on the 

 strength of your material, but you have got to be very careful 

 on peaches with that, or you will take the leaves off with it. 



President Rogers: Would you spray apple trees with 

 that strength? 



]\Ir. Henry : Yes sir. We have used it on apples one to 

 40 with arsenate of lead, and no harm done at all. 



A ]\Iember : You say that freezing does not hurt the 

 material or damage it? 



Mr. Henry : No sir ; it does not hurt it. It won't freeze 

 except at a very low temperature. It will stand zero weather 

 for a week and perhaps not freeze. After it is made it will
