insects and watch them grow and pass through their various moults 

 and transformations. 



In the fall the different cabbage worms will prove instructive 

 material for study, as they pass rapidly through their various trans- 

 formations. Many of the specimens collected at this time will have 

 been parasitized, and the emergence of the parasites from their host 

 will afford a valuable lesson on the work of beneficial insects. 



Many cocoons are likely to be brought in during the 

 fall and winter. A good disposition of these is to have 

 each pupil fasten his collection on a card and arrange the 

 cards as a frieze over the blackboards around the room. 

 When a moth is seen emerging, the card may be taken 

 down and the whole process watched.
