for their weight. They are more easily grasped if wood handles are 

 fitted around them. Bamboo rods are lighter, and therefore tire the 

 operator less. Those lined with aluminum sometimes cause trouble 



through the twisting off of 

 the connections at the lower 

 end of the rod. Where 

 aluminum is used the metal 

 should be of heavy gauge 

 at this point, and should 

 be one of the harder alloys.

 tension rod, and it should 

 have a handle of sufficient size to give a good grasp for turning 

 on or off. Unless rods are provided with an easily operated cut-off, 

 much spray material will be wasted in working from one part of a tree 

 to another or from tree to tree. 



Hose 



Hose leads are essential for barrel or power outfits. The length of 

 hose naturally varies with the character of work contemplated. If 

 two leads are used from a single pump, and one operator stands on 

 the spray wagon or on an elevated platform, it is convenient to have 

 the hose in two lengths, the longer for the man on the ground and the 

 shorter for the man on the platform. One half or three eighths inch 

 hose may be used. The former transmits the pressure to better 

 advantage; the latter is lighter to handle. 



Hose connections deserve consideration, especially in outfits designed 

 to work under considerable pressure, as in power apparatus. The long 

 connections, which admit of two bands on each side instead of one, 

 should be selected. 



In high-power outfits for shade-tree work, special hose is needed. 

 Connections are obtainable for this work which are provided with 

 bands fastened mechanically to the unions, so that the hose cannot 

 come apart when being dragged over the ground.
