When these materials are being used in the demonstration, they should 

 be handled in such a way that they are plainly visible to the audience. 

 Diagrams or charts will help to illustrate the feeding habits and 

 different kinds of mouth structures of insects, and other minute 

 processes and structures. 



To have their demonstration fundamentally sound and complete, 

 club members should make an exhaustive study of all the subject- 

 matter material available relating to their demonstration. In addi- 

 tion to using the material in this manual, club members may consult 

 such well-informed persons as the county agricultural agent, club 

 agent, or extension specialist, and obtain bulletins from them on the 

 particular subject being demonstrated.
