THE GARDEN PRIMER 



tion of galls, and lice always belong to the haustellate 

 class; but whichever the class, they must be suffocated 

 usually when they are subterranean or internal feeders. 



Spraying, or what the experts call the wet method 

 of applying insecticides, is not a difficult undertaking 

 but it demands suitable apparatus. It is the one way 

 of making applications thorough. The dry method — 

 application of poison in powder form — is useful in the 

 case of low growing plants sometimes, but is advisable 

 only when they are not to be used for food in the near 

 future. A third method of destruction is the use of 

 poisoned bait; this is used for cutworms and similar 

 insects that advance along the ground, like the grass- 

 hopper or locust. 



The size of a place and the consequent amount of 

 work to be done will of course determine the kind of 

 apparatus to be provided. There are many kinds of 

 small hand sprayers, as good a one as any being a small 

 brass or tin affair called an atomizer spray syringe. 

 This has a tank holding a quart of fluid ; for use around 

 a small garden it is very satisfactory because it may be 

 turned in any position without spilling its contents. 

 Thus leaves may be reached from underneath as readily 

 as from above. 



A bucket pump is of course better where there are 

 many shrubs or bushes; the ideal, suitable for every- 

 thing, is a spray outfit on wheels that may be moved to 

 any part of the grounds easily. And then there is a 

 knapsack spray which may be carried on the shoulders 

 of the operator; this is very much liked by some.
