These are not economical except where small operations 

 are to be carried on.

A man with five or six fruit trees can use the bucket 

 pump to better advantage than any other outfit that can be 

 secured. I don't believe it is necessary always to put in 

 large outfits. I have sprayed trees fifty and sixty feet tall 

 with the bucket pump. I find I can do this cheaper and just 

 as effectively as I can with a large pump.

Next comes the barrel pump. Up to orchards of over 

 five hundred trees I think this the best to be used. I have 

 tried all kinds of pumps and find with this I can use tw4" 

 lines of hose in one orchard, and I much prefer to use the 

 barrel pump. I believe we have struck the wrong end in 

 hunting for our pressure. Western entomologists all come 

 out for high pressure. I don't think it is efficient. I believe 

 it is more efficient to thoroughly cover our trees with the 

 spraying material. I also recommend the submerged barrel 

 pump with the air barrel under water. Nearly the entire 

 pump is in the barrel. The submerged pump works better 

 because we have the pressure under water. 



Automatic pumps, which are attached to the running 

 g-ear of apparatus, are not adapted for spraying of high land. 

 They are all right on level fields for crops, etc. 



In June, 1907, we bought a large outfit for spraying 

 pump — six horse power gasolene engine weighing 

 1,800 pounds. Pump weighed about 900 pounds. Imagine 

 the work of carrying around 2,700 pounds in engine and 

 pump. We used about 400 gallons of spraying material every 

 twenty minutes. Four hundred gallons weighs 3,200 pounds. 

 This meant a tremendous load. 



Last June the engine we had weighed 360 pounds. This 

 brings the engine down to a practical working basis. Our 

 pump today weighs 1,000 pounds. These are not satisfactory 

 pumps. They are cast-iron and are very heavy. Our next 

 move will be to get some one to build a pump that Avill be 

 light. 



The large grower will use a small gasolene engine one-^ 

 lialf and three or four horse power, and when spraying put 

 it somewhere where it will not freeze. It is almost impossi- 

 ble for the average man to draw off all the water. If any 

 remains it will freeze and ruin his pump. Buy a pump and
