TIVENTY.FIRST ANNUAL MEETING. 91 



ered. That is a mistake. The secret of the whole thino- is 

 to see how little you can put on and not how much. 



Mr. Ives: Will it kill all the scale? 



]\Ir. Repp: Yes sir, but you better let it take half the 

 scale off than kill the tree. You see, the way we spray we 

 carry it along with' the wind. The wand blows rig^ht ahead 

 of you, and the oil is so thin and the spray is so fine that the 

 wind blows it ahead of you. It is light. I have seen it blown 

 as much as two hundred and fifty or three hundred feet. We 

 do not have to stand there long, because the tree is greased 

 over almost before we get there to it. The breeze will carry 

 a lot of it into trees ahead of you. I have seen some men 

 put twice as much oil as they ought to into a tree. 



jMr. Rogers: Mr. Chairman, I would like to ask Mr. 

 Repp how much pressure he has on the pump when he puts 

 on this oil. 



Mr. Repp : We have a good strong pump man, and he 

 keeps on all he can get. 



AIr. Rogers : How much is that, — ten pounds or a hun- 

 dred pounds? 



Mr. Repp : I should say it would be a hundred and fifty. 

 You want to shove it right up so that you can hardly move 

 the handle, keep the pressure on, and then as you go along 

 to the next tree you just spray it a couple of times; just let 

 that thin cloud of greasy oil float into the tree. 



yiR. Kelsey : Do you have a pressure gauge on your 

 pump ? 



Mr. Repp : No. If I did the men would look at the 

 gauge all the time instead of pumping. 



Dr. Stewart of Penn : I do not want to say anything 

 to detract from the speaker's credit for what he has just said, 

 but I do not think I ought to sit here without saying just a 

 word on this question. I would like to have this audience 

 know that there is but one Repp, and a great deal of his suc- 

 cess with crude oil lies in the way he uses it down in N.ew 

 Jersey. A ,lot of people would not have as much success as 

 he has had. He also makes one statement that mav leave
