Has got to go inside, sir; 

 But kerosene with soap, to cream — 



It kills them through the hide, sir; 

 One ounce of soap, one quart of oil,

 Then keep well stirred. It is inferred 



These rules will save you millions." 



It is of great importance that we know these 

 insects. It is not necessary that we are able to 

 call them by name, but we should know enough 

 about them and their habits to be able to tell 

 whether they belong to the sucking or the chew- 

 ing class, in order that we may know how to 

 protect against them.
