PHYSIOLOGY OF THE HONEY-BEE. 



Experience has proved that impregnation may be effected 

 not only when there are no drones in the colony of the young 

 queen, but even when there are none in her immediate neigh- 

 borhood. Intercourse takes place very high in the air (per- 

 haps that less risk may be incurred from birds), and this 

 favors the crossing of stocks.
