way, get a quarter-inch drill, tap it out and put a gauge on. 

 Any plumber can put a guage on. It is easy to put a guage on 

 a pump and I should certainly never use a pump without a 

 pressure gauge on it, because oftentimes if you have three 

 or four going you can easily pick out the men that are doing 

 the hard pumping. It is the pressure that helps in the spray- 

 ing. So I say have a gauge on the pump and have plenty of 

 good hose. In spraying peach tree rows eighteen feet apart 

 we use at least twenty-five feet of hose, and we have found 

 the wire-wound to be very satisfactory, especially on stony 

 land. It prevents the hose from kinking. Where the hose 

 is wound with wire it is impossible for the hose to kink, and 

 it is kinking that breaks it. When wound with wire you 

 can't turn it short; it has to make a loop and it can't kink 

 and bend and be broken in that way. We like the wire- 

 wound hose. It only adds about 1 1-2 or 2 per cent, to the 

 expense of the hose and it lasts a good deal longer, especial- 

 ly on stony ground. 



We use angle nozzles entirely. TKey save a great deal 

 of walking especially on young trees. Where a person can 

 turn the extension rod from one side to the other and so 

 on, on small trees and large ones it saves a lot of walking. 

 If you have straight nozzles and want to use the "Y, " here 

 (indicating) is what is called an angle Y, a very handy 

 thing; but putting an angle nozzle on a straight Y, some- 

 times you have them working at each other and your sprays 

 hit together at the center; but with the angle Y and solid 

 nozzles, the nozzles have to be in the proper position and 

 your sprays will never intefere. I think that the disc noz- 

 zles are coming into use a good deal. They are all right if 

 you change them often enough. It is just a hole in some 

 east metal and it has got to be changed. When you 

 use lime-sulfui- sometimes you have to change the disc 

 every day. They only cost a couple of cents apiece and it 

 doesn't pay to fool with the old ones. If you use oil you 

 don't have to change so often, because the hole is small 

 enough so that you get the oil pressure. In your shutoffs 

 see that there is a good opening. Oftentimes I have seen- 

 a shutoff on the market and when you looked through it 

 it was all filled up from the casting and that left a very 

 small hole through. While you may have good pressure 

 in your pump you will have very small pressure in your 

 nozzle. See that they are clean all the way through. If 

 there is any obstruction from the casting, take a file and
