DR. FELT, I have 'not tested that out carefully, but it 

 has been tested by the Agricultural Experiment Station at 

 Geneva, and so far as .they have got at it at present, it works 

 very nearly as well as the lime-sulfur wash. There is a 

 variation of less than 1 per cent, in the case of San Jose 

 scale. This is necessarily based on only a few season's work. 

 I don't want to say too much about soluble sulfur. It is a 

 material which can hardly have been tested out thoroughly, 

 and I am a little curious to know what the results will be 

 when the application is followed shortly by heavy rains. 



MR. MANN OF ESSEX COUNTY. I notice you recom- 

 mend the combination of lime-sulfur and arsenate of lead in 

 spraying for codling moth. I think that is a very dangerous 

 doctrine. It may be safe in New York, where you haven't 

 the browntail and gypsy moth, but not in eastern Massachu- 

 setts. Here'in Massachusetts 3 pounds of arsenate of lead to 

 50 gallons of water just gives the browntail and gypsy moth 

 enough to get fat on, and don't do any good at all, and I 

 don't think that less than 5 pounds of arsenate of lead to 50 

 gallons of water is any use. That gives them enough so 

 that they stop business right away. 



As for the combined lime-sulfur and arsenate of lead, I 

 haven't used that combination, but I have repeatedly been 

 in orchards the first of the summer, where you could see the 

 foliage burned in some places quite badly, and I would ask 

 the man if he didn't use the lime-sulfur with the arsenate of 

 lead, and he would say, "Well, yes, we did use it on this part 

 of the orchard, but on most of it, we didn't," and in most 

 every place where I would see the foliage burned and the 

 fruit hard, it would be where they had used that mixture. 

 It may have been a climatic condition or perhaps it wasn't 

 put on right, perhaps they didn't use the right amount, but 

 at the same time, there was the damage and we ought to 

 know how to protect ourselves against it. In some places 

 where they used the highest priced poison of the lot, which 

 I suppose really is arsenate of lead and lime or Bordeaux 

 mixture, I noticed they had used it on their Mcintosh and 

 Gravensteins, and when they were ripe they didn't have a 

 fancy apple in the lot; — all blasted on one side where they 

 got that spray. We ought to know how to do these things 

 right.
