There is almost no limit to the number of insect-control practices that lend 
themselves to team demonstrations. Below are listed a few suggestive topics 
which may be developed according to the sample outline given. The subheads 
under each topic are control methods that should be demonstrated.

In addition to the team demonstrations on insect control, there are many 
other phases of the work with insects that can be presented by individual 
demonstrations. They are simple processes that may become part of a team 
demonstration. The following items may offer a few suggestions: 
Preparing insects to be sent away for identification. 
Making a collection net. 
. Making a jar for killing insects. 
. Pinning insects. 
. Making a spreading board. 
. Spreading butterflies. 
. Mounting butterflies for ornamental use.

EXHIBITS ° 
The primary object of an exhibit is to create interest. It is often 
difficult to tell an entire story with an exhibit. Quite frequently 
when people go where exhibits are shown, they do not take time 
to make a complete study of the whole exhibit. For these reasons, 
exhibits must be simple and so built that they will suggest the story 
without the use of too many legends. 
e Exhibits may be given at the August and September meetings. See calendar of activities 
for third-year work, p. 60.
