whips, and they wouldn't have large buds, but they would 

 have the regular one-year buds clear down to the bottom of 

 the tree. 



MR. HITTINGER: Wouldn't the eggs be dormant m the 

 buds? 



THE PRESIDENT: Yes, but you ought to be able to 

 see them. 



MR. G. N. SMITH : I had an experience in the spring of 

 1912 with the tent caterpillar and the aphis. Mr. Rees said 

 L might kill 80%, and I told him it killed them all, and I 

 thought that was 100%, and he agreed it was. Two years 

 ago the tent caterpillars were very thick, and the only ones 

 T had were on one side of a cherry tree that didn't get 

 sprayed. I came to the conclusion that the spray might kill 

 the tent caterpillar eggs at any season of the year, but now 

 J think we had better wait until they begin to hatch and the 

 eggs open. It seems to me that a spraying of lime-sulfur at 

 1 to 9 will kill every aphis it touches. If it don't touch it, 

 what is the use of adding Black-leaf-40? 



THE PRESIDENT: There is no question in my mind 

 about it killing the aphis itself, but I spoke of no effect on 

 the aphis eggs. 



MR. STOCKWELL: The speaker says we have got to be 

 very careful and not overdo spraying in the spring when we 

 use arsenate of lead, and we want to be very thorough, be 

 sure to touch every spot, but be sure not to do it too thor- 

 oughly. I would like somebody to draw the line there. 



THE PRESIDENT : I think it is impossible to draw that 

 line. 



MR. FARLEY : It is impossible to draw a mark between 

 too much and too little spraying, l)ut I know in some cases 

 we have sprayed too thoroughly and put on too much ma- 

 terial, with the result that we had serious burning. We 

 have drenched the trees so that there were puddles of spray- 

 ing material underneath. When you get to that point 1 

 think you have too much material on the trees as well as 

 under them, I don 't agree with some people as to the spray-
