 are many kinds of work to be done. The vegetable- 

 gardener can use outfits running from the power of 

 the vehicle wheels better than the orchardist can. Do 

 not buy a sprinkler or a machine which allows the 

 spray to fall by mere gravity. Have a pump. The 

 liquid must be thrown with force. Use a nozzle with 

 a small aperture, so that the material will be finely 

 broken. A nozzle has carrying power and distribut- 

 ing power. As a rule, the farther it carries, the less 

 finely it distributes the liquid. If possible, have the 

 nozzle near its work : force the liquid through a hose 

 rather than through the air. Have the nozzle on the 

 end of the hose ; and have the end of the hose where 

 the bug is. 



Secure a spraying outfit of large capacity. It is 

 more efficient and more economical of labor. Be sure 

 that the pump is strong, well made, brass-lined, and has 

 much power. Clean it thoroughly inside before putting 

 it away for winter. Get it out a month before it is

Spraying machinery has 

 come to be a necessity. No 

 one kind of pump or nozzle is 

 best. A nozzle which throws 

 a stream the farthest is the 

 least useful when it is desired 

 to apply the stream near at 

 hand. That is, that machine
