PHYSIOLOGY OF THE HOXEY-BEE. 



Exi)erieiice lias proved that impregnation may be effected 

 nut only when there are no drones in the colon j^ of the young 

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

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

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

 favors the crossmg of stocks.
