there is now practically no scale in the orchard, although 

 some three years ago every single tree was more or less in- 

 fested. There is practically no scale in the orchard now, 

 so apparently I haven't added enough lime to destroy the 

 insecticide effect and the fungicide value is certainly there 

 as to leaf curl, etc. 



Dr. Gilson. I am not an agent for any company, but I 

 will say that what I have comes from Vermont. But there 

 was grit. I don't think there was a quart or two in the 

 whole batch but what there was a lot of grit. 



Mr. Frost. In eastern Massachusetts you can get Ver- 

 mont Marble Lime which contains very little grit. There 

 are several very nice brands for that purpose. 



Mr. Castner. What time do you use lime-sulfur in the 

 spring ? 



Pres. Any time before the buds swell, from the first 

 of March to the ]st of May. 



Mr. Race. I understand, Mr. Henry, that you make 

 lime-sulfur and use it right away, putting in 15 pounds of 

 sulfur and 20 pomids of lime to 50 gallons of water. When 

 you make the concentrated you put in 60 of lime and 120 ot 

 sulfur. Is that right? 



j\Ir. Henry. Those proportions are practically right, 

 only for the concentrated that formula varies from 40 

 pounds of lime and 80 pounds of sulfur up to 60 and 130. 

 There are a good many different formulas right along in 

 there, and that has to be controlled by experiments. We 

 only use a high grade calcium lime, and very little magnesia. 



Mr. Race. Will that show when you spray the trees, 

 or is it like the commercial? 



Mr. Henry. No. It will show a little better than the 

 commercial, because it has a sediment. In the commercial 

 the sediment has been taken out, and the commercial doesn't 

 show up very well, and that is very serious. Of course, if 

 you have only a few trees and you are going to do it your- 

 self and know just what to do, then it is all right, but where 

 you have a big orchard the wind will change, blow heavily 

 down the rows and the spray will blow away in the or- 

 chard and the help have got to spray against the wind, we 

 know they won't know where they have sprayed and where 

 they have not. 



A Member. I should like to ask what kind of a noz-
