at that time is yet thin and the insect beneath it small and easily 

 atfected. 1 advise spraying with full winter strength just as 

 soon as possible after the leaves are off or even while a few 

 }et remain. Spraying is more easily done in fall than in 

 earl\- spring as a rule and the weather is apt to be more favor- 

 al)le. If you use "Scalecide" even a drench will do no harm 

 on any kind of tree. If you use lime and sulphur a few sappy 

 shoots of peach may be killed; but not enough to harm a tree 

 materially. 



In conclusion. I submit that the entomologist's work in the 

 matter of the pernicious scale is pretty well completed : what 

 remains is the mechanical problem of application, which is not 

 strictly in his line, but for which he has indicated the soluti(^n. 



At the conclusion of Prof. Smith's valuable address, which 

 was the most comprehensive and helpful presentation of the 

 scale question ever given before the Society, numerous ques- 

 tions were asked and answered. 



Discussion. 



Mr. Armstrong: What varieties of apples attacked with 

 scale are the most difficult to free from it? 



Prof. Smith : The Ben Davis is about as difficult a tree 

 as we have to deal with. 



A Member: How about the Baldwin? 



Prof. Smith : I don't know much about the Bald- 

 win: I don't think we grow that variety very much in New 

 Jersey. 



a' Membe:r: How much lime and sulphur do you use in 

 50 gallons of water ? 



Prof. Smith : Three gallons of water for one pound of 

 sulphur : the formula we use is 50, 50 and 50, of lime, sulphur 

 and salt, the three. 



A Member: Does the time of cooking have anything to 

 do with the efficiency of the mixture? 



Prof. Smith : It should be boiled until the lime and sul- 

 ])hur are combined; if you have as much lime as sulphur half 

 an hour of actual boiling is sufficient ; as a matter of care, I tell 

 people to boil it for 45 minutes. You can't boil the wash too
