LIVING MATERIAL FOR FALL USE. 
Grasshoppers and Crickets. Collect these insects 
and place them in tumblers, or similar glass vessels, 
covered with netting. Put earth 
in the bottom of each tumbler and 
keep it moist. Feed the insects 
with lettuce, or similar vegetable 
food. Watch the movements of 
male crickets while chirping. 
Female crickets may often be seen 
depositing eggs. The females 
may be recognized by the long, 
slender, egg-depositing organs at 
the end of the abdomen. Use 
these specimens with the directions 
in Chapter IV. Grasshoppers and 
crickets may be fed on bread. 
Wasps and Butterflies. Place 
wasps in tumblers in a similar 
manner, and feed them on sugar Fic. 2.—The House- 
and water. Try, also, butterflies cricket. 
and moths in the same way, using larger glass vessels. 
If eggs are deposited, examine them carefully and 
watch their growth.
