treated it should be thoroughly aired, taking care that 
no fire is near when the fumigating box is opened. The 
treatment may need to be repeated at times during the 
year. 
A School Display.—While collecting various kinds 
of seeds, nothing will add more to the attractiveness of 
the school room than a well arranged display. These 
seeds will also be of value in later studies of seed germi¬ 
nation and in preparing exhibits. It is easy to hang ten- 
ear bunches of seed corn upon the walls where they may 
be away from rats and mice. After drying, all the small 
grains may be displayed in glass jars or glass-covered 
boxes. These should be plainly labeled and arranged in 
a manner similar to that in Figure 10. The heads of 
grains, grasses and weeds may be tied in neat bundles for 
arrangement along the walls. Cardboard and a small 
supply of glue or library paste may be used in making 
a very attractive display of individual seeds. Figures 
11 and 12 were made in this way. 
Even a board with small holes, covered with glass, pro¬ 
vides a substantial mount which will protect the seeds 
from vermin.
