and while he is spraying with this one nozzle, the other is 

 shooting off into the air somewhere. When you are spray- 

 ing trees in foliage you may profitably use two if they are 

 set properly. If you spray with two nozzles, you must 

 Bee that they are set at an angle of about 60 degrees. I 

 know that a lot of you are spraying with nozzles set straight 

 on the end of the pole. You cannot do a good job with 

 them set that way. If you don't believe it, go home and 

 get one and try it. 



MR. GOULD. Would you recommend scraping off 

 the loose bark and spraying the trees? 



DR. WHETZEL. No, I never recommend anything. 

 Don't forget that I have recommended nothing to you to- 

 day, nothing. I wouldn't for the world have you say that 

 Whetz^el recommended this or that, and then have you cuss 

 me out. I wouldn't even suggest that you scrape the trees. 

 I don't scrape trees, because I haven't any to scrape. 

 [Laughter] . But if I had, I think I should not scrape them 

 unless I had a bad infection of the oyster-shell scale, say. 

 From the plant doctor's point of view there is no reason 

 why you should scrape trees. There are some however, 

 why you shouldn't. You are apt to injure the bark and 

 admit canker or something of the kind. It may be that 

 from the bug man 's point of view there is a need for scrap- 

 ing, but that is their problem. I don't know in respect 

 to that part of it. 



MR. REYNOLDS OF HAVERHILL. I would like to 

 ask if we get better colored fruit and fruit that will keep 

 longer, in a sod than we do where our orchards are culti- 

 vated? 



PRESIDENT FROST. Mr. Reynolds, I suggest that 

 that question be brought up this afternoon. Will you be 

 here with us? 



MR. REYNOLDS. I will. 



MR. RICHARDS. I am troubled some with my apples 

 with a dry rot that attacks the calyx. There will be a 

 space of perhaps a quarter of an inch around the calyx.
