pounds of arsenate of lead for fifty gallons for bud moth. 

 It has no effect or control of the apple scab. There is a 

 tendency on the part of growers to hold this spraying off as 

 long as possible, as near to the opening of the blossoms as 

 possible, in order to make one spraying do. In some sea- 

 sons it may be done, but is a dangerous practice. 



MR. W. F. GOULD OF IPSWICH. Will spraying have 

 any effect on honey bees? Is there any danger of their car- 

 rying the poison to their hives? 



DR. WHETZEL. I am afraid there are some bee men 

 in this crowd. [Laughter]. I got stung once and it put me 

 t^ntirely out of business, so that I am a little skeptical on 

 that ciuestion. In the first place there is no object in spray- 

 ing when the apples are in blossom, nothing to be gained, 

 because ordinarily it is a period in the growth and develop- 

 ment when there is clear weather, when the fungus will not 

 be active. If you spray properly it is done before the blos- 

 soms form, so that the bees and the poison would have no 

 relation to each other. In the state of New York, again, it 

 is against the law to spray when the trees are in blossom. 

 Professor Slingerland, however, said that there was no 

 evidence to show that the bees were poisoned, even if th'3 

 trees were sprayed when in blossom. It has been shown 

 however, that spraying in blossom tends to reduce the set 

 of the fruit. There are many good reasons why you 

 shouldn't spray in blossom, even aside from whether the 

 bees are injured or not. There is no reason why you should 

 spray in blossom, so far as I know. 



The other question that this gentleman asked in respect 

 to the curling and yellowing of the leaves, I suspect is 

 caused by lice, but I don't know. I am not a bug man, so 

 I can't give you any very good information. But I have 

 had some experience of my own, and I have concluded that 

 the lice is one of the big issues, I spent a good deal of time 

 chasing lice on a few small trees, so I haven't a suggestion 

 to make, because they got the best of me. [Laughter]. T 

 followed the advice of our staff and I found that the best
