Care of Spraying Machinery. 



It is always advisable to rinse out thoroughly the spraying 

 outfit and all utensils after use. Many of the spraying mix- 

 tures have a corrosive effect on metal parts, and scales of 

 metal "rust" often cause serious trouble by clogging the noz- 

 zles. As oil is very injurious to rubber it is advisable to 

 pump clear water through the hose after spraying with oil. 



Barrels and wooden tanks while not in use should be kept 

 partly filled with water to prevent drying out and leaking. 



Before spraying time arrives it is well to examine care- 

 fully the spraying outfit, to be certain that everything is in 

 readiness.
