cases to make not two, but three or even four applications 

 within a few days of each other, each with the wind in a dif- 

 ferent direction. This has been done in a few instances and 

 is perhaps advisable in very badly infested orchards or in any 

 place where there is reason for obtaining the very best results. 

 Here, as in many other places, one part insecticide to three 

 parts of application should be the rule. This formula is very 

 rarely given and too often overlooked by those who would ob- 

 tain good results in controlling this and other pests. 



Following Dr. Felt's excellent paper a number of ques- 

 tions were asked and answered. 



Mr. Wells : I would like to ask, Mr. President, this ques- 

 tion : If, with the steam pipes at sixty-five pounds pressure, 

 it is necessary to run them clear down to the bottom of the 

 barrels, and what are the different ways, if there are any, of 

 using it in the barrel? 



Dr. Felt : I think you should run your pipes down to the 

 bottom, of course, not quite to the bottom, and you should 

 also gauge the pressure just sufficient to make the water boil, 

 without having it boil up and carry the water and the mixture 

 out. Simply run the pipes well down, so that the steam will 

 do its work sufficiently, and without wasting the mixture. 

 Usually we have to shut the steam off a little, or it will be apt 

 to boil over, especially if the pressure is pretty good. 



President Gulley: It gives me great pleasure to an- 

 nounce the next speaker, who will speak to you on "Some 

 new spray mixtures for controlling the scale." It gives me 

 great pleasure to introduce Prof. C. P. Close, of the Delaware 

 Experiment Station, because he and I were boys together, 

 and later we have done a little work together, so that I know 

 something about him. I am glad to present to this audience 

 Prof. Close. 



Prof. Close: Mr. President, and members of the Con- 

 necticut Pomological Society, ladies and gentlemen : I am 

 very glad indeed to have the opportunity of presenting to you 

 this morning the results of the work which I have been doing 

 during the past season with some new spraying mixtures. I 

 have presented this subject at one other meeting of this kind.
