PROPOLIS. 



CHAPTEE XII. 



PROPOLIS 



Is a kind of cement used in Hves to fill up all holes and 

 cracks, and prevent unnecessary ventilation. It is a siil)- 

 stance not absolutely necessary to the wellheing of a 

 hive, but doubtless the bees derive benefit from using it, 

 otherwise they woiild not collect it. It is a sort of resin 

 or gum. A few ounces' weight, at most, is all that is found 

 in the largest hive. It is generally considered that the 

 bee-glue or propolis is collected from the buds of poplar 

 and other trees, and also from the resin of old pine-wood 

 exposed to the rays of the sun. -Doubtless, trees wounded 

 may yield some. It is a very much harder substance 

 than either wax or bee-bread.
