it is warm and very pliable. Then we take it out and put 

 on with a one-man pump, and put it on at just as high a pres- 

 sure as we can, just as hard as a man can pump. 



President Rogers: Do you use a tank or barrel? 



Mr. Repp: We use a tank that holds two barrels, 

 mounted on two wheels, and draw that through with one 

 horse. The pump sets on the tank. It is an ordinary barrel 

 pump. 



Mr. Drew: I would like to ask Mr. Repp to tell us 

 something about summer spraying, and the amount of pres- 

 sure that he puts on in the summer spray work; and a little 

 more in detail as to how he goes at it in the summer time. 



Mr. Repp : We use a pressure nozzle of about two to 

 three hundred pounds. We use two lines of hose. It takes two 

 men to run them. One man drives and one runs the engine. 

 Then we have three nozzles on each hose. Each of them is 

 a very fine mist nozzle. We do not use any of the coarse 

 nozzles at all. 



Mr. Drew: How many times do you spray? 



Mr. Repp: We commence with the Red Astrachan ap- 

 ples. Those are early apples and we take them first. Some- 

 times we do not spray as much for the other varieties. Alto- 

 gether we sometimes spray four times. 



Mr. Drew : Do you find it makes any difference what 

 material you use? 



Mr. Repp: Not in the matter of ripening, no sir. 



Mr. Platt: Mr. Repp, do you have any trouble with 

 the pear psylla on your pears? 



Mr. Repp : We have had them for several years, but 

 when this pear psylla began to bother us we scraped the bark 

 the next month, and then sprayed the trees with the crude 

 oil, and it knocked out the pear psylla completely. If we did 

 not use the crude oil and scrape off the rough bark, we would 

 be pretty sure to have the pest another year. We scrape off 

 the bark of the pear tree, and the rough bark on the apple. 

 The pear psylla would hide under that bark. You must scrape
