MY GROWING GARDEN 



Most of all, he needs to be sure to cover every 

 least twig of the trees and shrubs with the thinnest 

 coating of the spray. At least twice each tree 

 needs to be hit with the finest possible mist, high 

 and low, right and left, and from all sides. To see 

 to it that the nozzle of the spray tool is clean and 

 clear, and to filter every drop that goes into the 

 tank through a sieve good enough for the gasolene 

 that is to run your automobile, will make for good 

 work in the shortest time with the least waste. 



As to what spray machine to use, I don't know ! 

 I have some seventy-five-cent hand syringes, an 

 acceptable shoulder-tank affair, and a barrel-pump 

 machine mounted on wheels. Any one of them 

 works when it works, and is abominable when it 

 doesn't. The thing to be accomplished, as I have 

 said, is to get every twig thinly but completely 

 covered with the spray fluid. Drops hanging down 

 are no indication of anything but much fluid; the 

 upper surface of the limb from which the drop 

 hangs may be entirely free from needed spray- 

 coating. It is desirable to get the highest pressure 

 of air possible against the liquid to be sprayed, 

 so that a wide-spreading fine mist issues from the 

 nozzle. Pervasiveness, and not quantity, is what 

 counts and kills. 



Persistence, care, observation — all these I have
