PROPOLIS. 
Propolis is a sticky substance like resin. 
It is gathered from certain trees, and is made 
use of by the bees for closing up all the small 
crevices in the interior of their hive, and for 
fixing the hive to the floor-board, so as effec- 
tually to bar the entrance against any enemy 
from without.
