almost impossible to do as cheap a job with a spray gun as it 

 is with a spray tower and two rods? 



Professor Whetzell. No, it is possible to do as good a job 

 with the spray gun, in my opinion, but it ordinarily isn't done 

 that way, for the reasons I pointed out. If you have a man on 

 the ground and another one on the tower, on a 10 or 15 foot 

 tower, with a good angle nozzle on the end, you apply so much 

 spray per second, and you cover all parts of the tree, and you 

 do not drench any part of it. If a man is out on the tower 

 with a spray gun, and another man on the ground with a spray 

 gun, and the trees were not so large but what you could shoot 

 this mist into the middle of the tree, you can do just as good 

 a job, and applying so much more mixture per second you have 

 to be on the job constantly. That is what happens. The hired 

 man turns on the gun, and the more stuff he can get out of it, 

 the better it looks to him, and he drenches the trees in spots. 

 I saw an orchard in Nova Scotia sprayed with a spray gun 

 where the fellow shot the tree; he took all the leaves and 

 apples off. 



Chairman Jenks. If you were doing the job yourself, and 

 of course wanted to save time and expense, would you be 

 inclined to use the gun or the rod? 



Professor Whetzell. I never had any extensive experience 

 with the gun on my own account, but my own opinion is that 

 I would stick to the pole and get a big angle nozzle on the end 

 of it. I think I would save enough material and do enough 

 better job to warrant me using the pole and nozzle than I 

 would with a spray gun. I have seen some men spraying with 

 a spray gun, especially if the trees were small, and they were 

 up on the wagon, do a pretty good job with it, but I have 

 seen many more men, who opened it wide to get to the top 

 of the tree, do a poor job on the top and drench the trees 

 below. So that in the hands of the ordinary man, the average 

 man, I believe that better work will be done with a pole and 

 nozzle than with a spray gun. That is not saying you can't 

 do good work with a gun. 



Chairman Jenks. It is particularly applicable to high trees? 



Professor Whetzell. Particularly so, yes, sir, and particu- 

 larly applicable to the man who isn't very much interested in
