74 INSECT PESTS OF FARM GARDEN AND ORCHARD 



Connections and Cut-offs. Rose connections are important. 

 Nothing is more aggravating than to have the hose pull loose 

 from its connections while operations are in progress. To prevent

this, use only connections with long shanks which may be fastened 

 with two hose-clamps over each shank. Fig. 52 shows this type 

 of connection and an adaptation of it used for mending breaks in 

 hose or in splicing permanently two lengths of hose. A cut-off 

 at each rod is necessary and this should be of 

 a leak-proof type. A three-way cut-off at the 

 pump is also necessary where there are two lines 

 of hose operating With these there is complete 

 control of the spray and one line can stop for 

 repairs while the other continues to work. 



Towers. Many operators like to use a tower 

 for spraying large trees and many of the power 

 sprayers are equipped with towers. Their 

 value is questionable, however, and many 

 laborers refuse to work in them. It is quite 

 al- probable that just as good work can be done, 

 lows the hose lead in most cases, by using longer rods and reach-

tion as he is when on the tower. The spray-gun does away with 

 the need for the tower where it is used as it will reach the top of 

 the tallest tree. 



Strainers. To obviate the delay caused by nozzles clogging 

 with dirt and sediment, strain all mixtures through a fine copper 

 strainer when filling the spray tank. Have the tank tight and 

 see that it is clean before filling.
